Pre-implementation technical design agent. Spawn when you need a structured technical plan before writing code. Reads the codebase, identifies patterns and constraints, evaluates approaches, and produces a concrete plan a Worker can execute directly. Never writes or modifies files.
General-purpose implementation agent. Spawn for any code change: new features, bug fixes, refactors, configuration changes, or script writing. Reads the codebase to understand conventions, implements the change, runs quality gates, and returns a clear summary of what was done. This is the standard Worker for all Elevated-risk implementation tasks.
Cheap per-turn stop-condition check for open-goal loops. Spawned by the conductor ONLY after an Elevated iteration produces a clean Skeptic sign-off, to evaluate the operator-declared goal_condition and return continue-vs-stop only - never for a Low/Trivial iteration (no Skeptic sign-off exists to run after; the conductor evaluates goal_condition directly there instead). Tier 1 (haiku) leaf agent - read-only, no subagent spawning, never runs in place of, before, or concurrently with a Skeptic review. Does NOT review correctness or safety and does NOT raise, waive, or comment on Skeptic findings. Returns BLOCKED only as a structural guard when spawned without a confirmed Skeptic sign-off; the conductor handles this BLOCKED as a fallback to direct evaluation, NOT as the generic Worker-BLOCKED-means-cap_reached-escalation semantics in content/references/subagent-protocol.md - a BLOCKED return here never halts the loop. On any other failure (unavailable, errored, timeout, malformed output) the conductor falls bac

Run the Activation preflight from
METHODOLOGY.mdbefore proceeding. If inactive, no-op and exit.
Context-size preflight (run immediately after Activation, before any other step): Assess the current session's context load against the soft and hard limits defined in
content/references/subagent-protocol.mdSection 13.Hard limit check (Section 13.2) - checked first: If the session has reached the hard limit, Section 13.2 governs absolutely - there is no
yes/proceed override at or above the hard limit. Do the following in this order: (1) print the hard-limit block below verbatim, (2) invoke/ds-wrapautomatically to preserve state viacontext.mdandMEMORY.mdupdates (or instruct the operator to run/ds-wrapif auto-invoke is unavailable in the current harness), (3) exit - refusing further implementation work, Skeptic rounds, and subagent spawns for the remainder of this session. Do not print the soft-limit warning block below or the "Proceed anyway?" prompt.Hard-limit block (print verbatim - this is a plain print, not an
AskUserQuestiontool call, and does not wait for operator confirmation):Context-size hard limit reached: this session has reached the conductor context hard limit (Section 13.2 of the Subagent Protocol). The hard limit is absolute - there is no override, and further implementation work, Skeptic rounds, and subagent spawns are refused for the rest of this session. Why: the hard limit exists to protect output quality. A conductor operating past this point risks missing details from earlier turns, re-introducing bugs already fixed, and producing stale crash-recovery state. A fresh session is required to continue - this is not optional. Next steps: 1. /ds-wrap - save session state and generate a hand-off summary 2. Start a new session (on Claude Code, /clear also works) 3. /ds-implement-ticket <your input> - in the fresh sessionDanger signals below the hard limit (any one triggers the soft-limit warning, per Section 13.1):
- Session turn count at or above the soft limit with substantive tool-call results still in context.
- Any prior subagent result block, of substantive size, is visible and was produced in this same session before
/ds-implement-ticketwas invoked.If a danger signal is detected below the hard limit, print verbatim (this is a plain print-and-wait for the operator's next message, not an
AskUserQuestiontool call):Context-size warning: your current session carries significant prior context (a long turn history and/or one or more prior subagent result blocks still visible). Running /ds-implement-ticket now risks exhausting your token budget before the architect-plan-review phase completes. Recommended safe pattern: 1. /ds-wrap - save session state and generate a hand-off summary 2. Start a new session (on Claude Code, /clear also works) 3. /ds-implement-ticket <your input> - in the fresh session Proceed anyway? (yes / no)On
no: exit immediately. Onyes: continue with a one-line note:Context-size warning acknowledged - proceeding in large session.Thisyesoverride is valid only below the hard limit - it never applies once the hard limit is reached (see Hard limit check above).If no danger signals are present: continue silently (no output).

/ds-implement-ticket <input>
<input> accepts any of:
DINO-639DINO-639, DINO-638 or DINO-639 DINO-638/browse/DINO-639, Linear /issue/ENG-42/.../issues?jql=..., Linear filter URL.agentic/phase0-classifiers.ymlPhase 0 normalizes the input into a canonical ordered list of ticket entries before any other phase runs. Bare-ID, single-issue-URL, and operator-enumerated list invocations bypass the confirmation prompt — backward compatible with the prior single-argument contract.
Open-goal / wallclock-cap parameters (optional, trailing key=value tokens). <input> may be followed by any of goal_mode=open_goal, goal_condition="<string>", max_iterations=<int>, max_wallclock_min=<int>, dry_run=true. Extracted by a trailing-token scan (\w+=(\S+|"[^"]*")) BEFORE Phase 0 classification runs; matched tokens are stripped so ticket-reference classification is unaffected. dry_run is meaningful ONLY when goal_mode=open_goal is also present - on any other invocation shape it is parsed and explicitly ignored (no effect, no error).
The conductor delegates implementation work aggressively to specialist subagents but retains a fixed set of responsibilities that are never delegated. This section enumerates at minimum:
.agentic/*.json[l] writes. Sole-writer rule for loop-state.json, tasks.jsonl, and any other state file under .agentic/.[phase: ...] and [loop: ...] emissions originate from the conductor.BASE_BRANCH resolution and AGENTS.md config parsing. Setup phase work.gh pr create in Phase 9. PR opener stays in the conductor; the synthesis output is consumed inline by the next phase and does not benefit from isolation in a separate spawn.This list is not exhaustive — any operation listed elsewhere as conductor-direct is also irreducible.
These contracts govern every conductor write to .agentic/batch-state.json and .agentic/loop-state.json. Phases that write to either file (Phase 0a, Phase 0a-pre, Phase 6/6b, Phase 7, Phase 12, Phase 12a) MUST apply the contracts below.
Contract A — Per-write session_id gate (applies to BOTH batch-state.json and loop-state.json).
Before every conductor write to either file:
session_id field is a non-empty string AND does not match the current session, AND its last_updated is within the last 10 minutes: ABORT the write. Print the verbatim warning:
WARNING: write to .agentic/<file> aborted - another session (session_id=<X>, last_updated=<Y>) appears to own this file. Identify the live session via .agentic/*.json last_updated. Resolve manually (kill the other session, or remove the file) and retry.
session_id is null/missing/empty (legacy state from a prior version): treat as mismatch — force-takeover-eligible. Operator may resolve via the Phase 0a-pre force-takeover prompt or by manually removing the file. The same WARNING above is printed.session_id, or stale > 10 min): proceed with the write. Set session_id to the current session's id and update updated_at in the new payload.Both readers and writers tolerate absence of session_id for back-compat with state files written by prior versions; absence is treated as mismatch for write-gating but not for read-only resume prompts (those follow the Phase 0a-pre decision table).
Contract B — replan_log[] read-merge-write preservation (applies to batch-state.json).
Every conductor write to batch-state.json MUST:
replan_log[] from disk and merge any new entries authored in-memory by the current conductor turn (append-only; never reorder; never drop entries).This preserves the audit log across overlapping writes and across resume migrations.
Contract C — One batch per project root.
When Phase 0a is initializing a new batch-state.json (invocation where Phase 0 produced ≥ 2 entries, OR Phase 0a-open-goal is performing a Fresh init (goal_mode=open_goal), OR the Phase 0a-pre single-ticket-capped carve-out is performing its create (max_wallclock_min alone, no goal_mode)) and the file already exists with status=active, a different session_id, and last_updated within the last 10 minutes: REFUSE the new batch with the verbatim message:
Another batch session is active for this project root (session_id=<X>, last_updated=<Y>). Wait for it to finish, or kill it and re-invoke.
Concurrent batches per project root are not supported. Operators wanting parallel batches use separate worktrees with separate .agentic/.
N=1 foreign-batch warning. If Phase 0 produced exactly 1 entry (single-ticket) AND .agentic/batch-state.json exists with status=active + different session_id + last_updated within the last 10 minutes: print the verbatim warning:
NOTE: a batch session is active for this project root (session_id=<X>, last_updated=<Y>). Single-ticket invocations are not refused, but loop-state.json writes will collide if the same ticket is touched. Identify the live session via .agentic/loop-state.json last_updated. Continue? (yes/no)
On no: abort. On yes: proceed with the single-ticket flow. This is the only single-entry interaction with batch-state.json.
Contract D — Stop hook mirror.
The Stop hook (hooks/stop-context.js) mirrors its loop-state.json interrupted-mark write to batch-state.json via the helper writeBatchState(cwd, sessionId). The mirror applies an ownership check: if the file's session_id is a non-empty string and does not match the Stop hook's session uuid, the write is aborted silently (the hook does not steal another session's batch state). Best-effort silent-fail throughout. The mirror sets status=interrupted, interrupted_at=now, interrupt_reason="unknown", updated_at=now; all other fields including last_updated_phase, tickets[], and replan_log[] are preserved.

Field semantics:
schema_version: integer; current is 1.session_id: uuid of the conductor session that last wrote the file; null only on legacy files written by a prior version.batch_id: stable identifier for the batch. Format <prefix>-batch-<ISO8601>-<4hex> where <prefix> is the first ticket's TICKET_PREFIX (used when tickets span multiple prefixes; the first ticket wins).status: enum active | paused | interrupted | complete | stalled.mode: enum "batch" | "open_goal" | "single_ticket_capped". Absent = "batch" (100% back-compat). "open_goal" is set by Phase 0a-open-goal's Fresh init; "single_ticket_capped" is set by the Phase 0a-pre single-ticket wallclock carve-out - the ONLY N=1 path that creates batch-state.json.interrupt_reason: enum unknown | null — only unknown is a writable value (other values reserved for future writers; the Stop hook cannot distinguish rate-limit vs crash at hook time).pause_reason: enum stale_pace | operator_pause | wallclock_cap | open_goal_iteration_cap | null - these four values match the four Phase 12a triggers. NOTE: paused_stale_pace / paused_operator_request / cap_reached_wallclock / cap_reached_iterations / goal_met / blocked are open_goal.termination_reason values, NOT pause_reason values - deliberately avoiding a dual-enum collision. Only open_goal_iteration_cap was added to pause_reason; triggers 1-3 keep their existing pause_reason values stale_pace / operator_pause / wallclock_cap.wallclock_started_at: set once at Phase 0a init; preserved across resume. The wallclock cap is per-batch lifetime, not per-session.wallclock_cap_min: integer minutes. Default 90. Overridable via env AGENTIC_BATCH_MAX_WALLCLOCK_MIN.tickets[]: triage-derived executable cursor; contains only lane-assigned tickets (deferred and in-progress-excluded tickets are not included). status per-ticket is pending | in_progress | complete | blocked | skipped_already_merged.replan_log[]: append-only audit log. Each entry: {ts, action, ticket_id, detail}. Actions include drop_merged, investigator_rerun, re_sequence. Preserved by Contract B.open_goal: present (meaningfully populated) only when mode == "open_goal". active: boolean, whether an open-goal loop is currently running. goal_condition: operator-declared condition string, set once at Fresh init, read-only thereafter (divergent re-invocation values are warned and ignored - on-disk governs). iteration: current iteration number; invariant iteration == len(tickets[]) from the first synthetic entry onward (SOLE momentary exception: immediately after Fresh init, iteration=1 but tickets=[] - closed the moment Phase 1 of iteration 1 appends its entry). max_iterations: operator-declared cap, mandatory at Fresh init, no default. risk_declared: this iteration's risk classification (low | elevated | trivial), written at Phase 6 clean exit - the DURABLE audit record (see content/references/trigger-catalog.md §Risk and review discipline (c)). termination_reason: enum null | cap_reached_iterations | cap_reached_wallclock | goal_met | blocked | paused_stale_pace | paused_operator_request - partitions TERMINAL (cap_reached_iterations, cap_reached_wallclock, goal_met, blocked) from RESUMABLE (paused_stale_pace, paused_operator_request, or null with status in {paused, interrupted}). dry_run: boolean, set once at Fresh init, never changes mid-loop; when true, Phases 6b/8-11b are skipped for every iteration (no QA, no ship, no PR) - see Phase 6b and Phase 8 dry-run gates.Before reading AGENTS.md or doing any setup, check for .agentic/loop-state.json:
If the file exists and status == "interrupted":
last_phase / last_phase_action per the table below.If the file exists and status == "active" with last_updated more than 10 minutes ago: treat as implicitly interrupted (the Stop hook may not have fired). Print: "Found an active loop state last written [elapsed] ago — treating as interrupted." Then follow the "interrupted" path above.
If the file exists and status == "complete" or "stalled":
If no file exists: proceed normally.
Wait strategy (applied before resuming when interrupt_reason == "rate_limit"):
elapsed = now() - interrupted_at
if interrupt_reason == "rate_limit":
if elapsed < 60 seconds:
wait_remaining = 60 - elapsed

Resume entry point table:
| last_phase | last_phase_action | Resume action |
|---|---|---|
| skeptic | spawned | Re-spawn Skeptic with current diff (git diff origin/$BASE_BRANCH..HEAD). On iteration 2+, include prior-iteration findings block from findings_log (same as normal iteration 2+ behavior). |
| skeptic | returned | Skeptic output was received but Engineer fix pass was not yet spawned. Re-classify findings from findings_log (entries with status=open) and spawn the Engineer fix pass. |
| engineer | spawned | Check git status --porcelain on the branch. If clean: re-spawn Engineer with same open findings brief. If dirty (uncommitted changes): ask human "The Engineer had uncommitted changes. Discard and re-run, or commit what's there and re-run Skeptic?" |
| engineer | returned | Engineer returned but loop did not advance. Use last_engineer_summary from state file. Re-enter Skeptic spawn step. |
| qa | spawned | Re-spawn QA engineer with the prior brief. |
| qa | returned | QA engineer returned but loop did not advance. Re-spawn Engineer fix pass for QA failures. |
| quality_gate | engineer_spawned | Check git status --porcelain. If clean: re-spawn Phase 7 engineer with quality gate failure output from loop_state.last_engineer_summary. If dirty: ask human (discard and re-run, or commit and re-run $QUALITY_CMD). |
| quality_gate | engineer_returned | Phase 7 engineer committed. On the Elevated path: verify the engineer's reported quality_gate_results. On the Trivial path: re-run $QUALITY_CMD. |
| quality_gate | rerun_pending | On the Elevated path: wait for the fix-engineer return and verify its quality_gate_results - do not invoke $QUALITY_CMD directly. On the Trivial path: re-run $QUALITY_CMD. |
| quality_gate | debugger_spawned | Re-spawn Debugger from scratch with the captured gate failure output (Debugger is read-only and idempotent - same pattern as "Full Skeptic re-run on interruption"). |
| quality_gate | debugger_returned | Debugger output was captured before interruption. Proceed to spawn the next engineer fix pass with the Debugger's Fix brief. No Debugger re-run needed. |
| ci_wait | timeout | Re-enter Phase 10 poll loop once (operator may have manually fixed; if still timing out, re-escalate). |
| ci_loop | fix_engineer_spawned | Re-spawn the fix engineer from the latest commit on the branch (assumes prior spawn was interrupted). Resume from cycle N. |
| ci_loop | fix_engineer_returned | Re-enter Phase 10 poll loop to check CI status. |
| ci_loop | ci_poll_pending | Re-enter Phase 10 poll loop from current iteration. |
| ci_loop | cap_exceeded | Do NOT auto-resume. Surface the prior escalation summary and require human direction. |
After resuming: always run git -C $REPO diff origin/$BASE_BRANCH..HEAD to confirm branch state before re-spawning agents. If the diff is empty and open findings exist, the Engineer's prior work was lost (uncommitted at interruption); flag this to the human before resuming.
Parse failure: if .agentic/loop-state.json exists but cannot be parsed as JSON, print a warning, offer to delete the file and start fresh. Do not silently ignore it.
Concurrent session guard. REPLACED in this version by Contract A's per-write session_id-mismatch abort gate, applied to every conductor write of loop-state.json and batch-state.json. See Phase 0a-pre and the "Batch state contracts" section above for the full contract. Every conductor write to loop-state.json includes a top-level session_id: <current session> field; readers tolerate absence for back-compat with state files written by prior versions.
N=1 foreign-batch warning. Before proceeding to Phase 0a-pre on an invocation where Phase 0 produced exactly 1 entry, apply the N=1 foreign-batch check from "Batch state contracts" above. If .agentic/batch-state.json exists with status=active + different session_id + recent (≤10 min): print the verbatim NOTE, prompt yes/no, and abort on no.
Before any phase, read the project's AGENTS.md and extract the following values:
REPO — absolute path to the repo rootGH_REPO — GitHub repo slug (e.g. org/repo-name)BASE_BRANCH — the branch all work is based from. Resolve in this order: (1) if declared via a BASE_BRANCH: line in AGENTS.md, use that; (2) else develop if it exists locally; (3) else development if it exists locally; (4) else stop and ask the user: no develop/development integration branch found - use main (falling back to master), or set up a develop-based workflow? Offer main as the recommended default; (5) on decline / main preference, resolve main (fall back to master). Do not auto-create a branch. Once resolved, print: BASE_BRANCH resolved to: [value].QUALITY_CMD — the full quality gate command to run from repo rootDEBUGGER_ON_FAILURE — read from .agentic/config.json key debugger_on_failure (boolean, default false). When true and the path is Elevated, a Debugger diagnosis step is interposed between a failed quality gate and the next engineer fix pass in Phase 7 - see Phase 7 for the full flow.AUTO_MERGE_ON_CI_GREEN — read from .agentic/config.json key auto_merge_on_ci_green (boolean, default false). When true, Phase 12 squash-merges the PR after CI passes, the PR is ready, and no reviewer has requested changes. Default false leaves the PR open for human review.PR_WORKFLOW_REVIEWERS — read from AGENTS.md ## PR Workflow section, Reviewers: field (comma-separated GitHub usernames). Default: empty string. Section absence = empty. Used in Phase 10b as fallback reviewer assignment when no CODEOWNERS file is found.Tracker resolution — read tracker config using this fallback chain:
## Tracker section exists in AGENTS.md and contains TRACKER: jira: set TRACKER=jira. Extract TICKET_PREFIX, JIRA_BASE_URL, JIRA_QA_ASSIGNEE_ACCOUNT_ID (optional), JIRA_QA_TRANSITION (optional — no default). Also extract optional state-name overrides: JIRA_STATE_IN_PROGRESS → TRACKER_STATE_IN_PROGRESS (default "In Progress"), JIRA_STATE_IN_REVIEW → TRACKER_STATE_IN_REVIEW (default "In Review"), JIRA_STATE_QA → TRACKER_STATE_QA (default "QA"), JIRA_STATE_BLOCKED → TRACKER_STATE_BLOCKED (default "Blocked"), JIRA_STATE_DONE → TRACKER_STATE_DONE (default "Done"). All five fields are optional; absence = use default.## Tracker section exists with TRACKER: linear (future-proofing): treat as Linear and read Linear fields from ## Tracker instead of ## Linear. Apply the same state-name override fields as the Linear path below.## Linear section exists: set TRACKER=linear. Extract Team → TICKET_PREFIX, Workspace → LINEAR_WORKSPACE, QA assignee ID → LINEAR_QA_ASSIGNEE_ID (optional). Also extract optional state-name overrides: State In Progress: → TRACKER_STATE_IN_PROGRESS (default "In Progress"), State In Review: → TRACKER_STATE_IN_REVIEW (default "In Review"), State QA: → TRACKER_STATE_QA (default "Testing"), State Blocked: → TRACKER_STATE_BLOCKED (default "Blocked"), State Done: → TRACKER_STATE_DONE (default "Done"). All five fields are optional; absence = use default. (Note: Linear TRACKER_STATE_QA defaults to "Testing" while Jira defaults to "QA" — reflects common workspace conventions for each tracker.)TRACKER=none. Set all TRACKER_STATE_* variables to their defaults: TRACKER_STATE_IN_PROGRESS="In Progress", TRACKER_STATE_IN_REVIEW="In Review", TRACKER_STATE_QA="Testing", TRACKER_STATE_BLOCKED="Blocked", TRACKER_STATE_DONE="Done".Dual-shape note: Linear projects canonically store tracker config under ## Linear; Jira projects use ## Tracker. This is intentional — it preserves zero-migration compatibility for every existing Linear project that already has a ## Linear section.
Legacy ## Linear shape guard — if TRACKER=linear was resolved from a ## Linear section AND the section is missing the Workspace: field (required for URL generation), stop immediately and print:
Your tracker config is missing fields /ds-implement-ticket needs. Run /ds-init-project to update it —
discovery will fill in most fields automatically.
Do not continue. Do not attempt to write the migration. All config-mutation logic lives in /ds-init-project.

Reusable subagent invocation pattern. Used by Phase 11 (existing) and 7 new sites below. Gated on TRACKER != none; no-op otherwise.
Invocation contract:
When the conductor reaches a writeback boundary:
TRACKER == none.general-purpose) in background (fire-and-forget; do NOT wait for return before continuing the phase).tracker: linear | jiraticket_id: from current task contexttarget_state: one of the resolved TRACKER_STATE_* variablesforward_only_guard: true for all 7 new sites; preserves existing Phase 11 behavior (which used hardcoded Testing)LINEAR_WORKSPACE, LINEAR_QA_ASSIGNEE_ID for Linear; equivalent for JiraSubagent responsibilities (extended for forward_only_guard):
Pre-read current state: call mcp__linear__get_issue (or Jira mcp__mcp-atlassian__jira_get_issue) to read the ticket's current state including state.type (Linear: backlog, unstarted, started, completed, cancelled; Jira: map via status category).
Forward-only guard: compute rank of current state and target state.
Linear ranking (uses state.type directly):
backlog < unstarted < started < completed; cancelled is terminal (never overwritten by any automatic transition).
Jira ranking (map via status category, available on every Jira status via statusCategory.key):
new (To Do, Open, Backlog) → rank unstartedindeterminate (In Progress, In Review, Testing) → rank starteddone (Done, Closed, Resolved) → rank completedApply the same rank-comparison rule for both trackers: if current rank >= target rank, skip the transition.
Skip semantics:
cancelled: skip transition unconditionally.mcp__linear__save_issue (or Jira equivalent).Soft-fail: any transition error logged to stderr; subagent returns { "status": "failed", "errors": [...] }. Conductor logs and continues; never blocks the phase.
Failure logging: subagent stderr is captured by the conductor's agentic-emit event; one operator-visible line per failure of the form: tracker-writeback: <ticket_id> -> '<target_state>' FAILED: <error>. No block.
For full details of the Phase 11 writeback subagent brief shape, see the Phase 11 block below — the brief is unchanged except for the addition of target_state and forward_only_guard parameters.
Reusable SYNCHRONOUS pattern - the conductor waits for the new ticket ID before routing to /ds-implement-ticket. Called by the ticket-offer gate (cross-ref content/sections/02-delegation.md §Ticket-offer gate).
Invocation contract:
Caller supplies:
TICKET_TITLE - one-line summary of the workTICKET_BODY - markdown description; include Problem + Acceptance Criteria when knownTICKET_TYPE - feature | bug | taskHelper returns:
CREATED_TICKET_ID - e.g. DS-42; empty string on failureCREATED_TICKET_URL - empty string on failureCREATE_STATUS - created | skipped | failedCREATE_ERROR - error message string, or null on success
Collision pre-check (runs BEFORE the create branches):Before calling any tracker create API, scan in-flight tickets in the same tracker project/team for overlapping output surfaces. Overlap surface = same source files, same exported symbols, same DB tables/migrations, or same shared utility/config that the proposed TICKET_BODY scope touches. This is the cross-ticket boundary analysis that prevents two parallel sessions from colliding on the same file - the failure mode where a boundary gets retrofitted AFTER the ticket already exists instead of at creation time.
Scan target: open AND in-progress tickets in the same project/team. For Linear: mcp__linear__list_issues filtered by team and state not in (Done, Cancelled). For Jira: mcp__mcp-atlassian__jira_search with project JQL scoped to statusCategory != Done. For trackers with no query branch: skip silently (fail-safe - the boundary-in-body rule below still applies but relies on the conductor's own scope knowledge rather than a scan).
Decision:
No overlap, OR tracker has no query branch: proceed to the create branches with TICKET_BODY unchanged.
Overlap found: append a ## Scope boundary section to TICKET_BODY BEFORE the create call. The section names the overlapping ticket(s) and the file/symbol/table each side owns. Worked example (AUT-301 vs AUT-300, both touching the operator-list surface):
## Scope boundary
- AUT-300 owns: packages/qa-auth/src/adapters/admin.ts (prod-DB guard), admin/scripts/seed-qa-operator.ts, and any isTestAccount schema migration if that route is chosen.
- This ticket owns: backend/src/operators/index.ts GET /operators WHERE-clause filter only.
- Merge order: this ticket is the symptom-fix; AUT-300 is root-cause. If AUT-300 adds an isTestAccount flag, that migration is AUT-300's to own.
The boundary section is binding, not advisory: it travels with the ticket into the tracker so the other session sees it on its next pull. If the conductor cannot determine a clean boundary (the two tickets genuinely own the same lines with no split), STOP before creating and surface the conflict to the operator for a manual scope-split.
The scan is a single tracker query (one API roundtrip, paginated to the project/team). It is cheap and runs only at create time - it does not run on every phase transition.
Branch on TRACKER:
TRACKER == linear: call mcp__linear__save_issue with NO id field (save_issue creates when no id is supplied - this matches the repo's existing Linear convention; do NOT use a createIssue tool, it does not exist). Pass title=TICKET_TITLE, description=TICKET_BODY, and the Linear team. IMPORTANT team-source note: the ## Linear section's Team: field resolves to TICKET_PREFIX (a prefix string like "DS"), but save_issue needs the Linear team key/id - if only a prefix is available, resolve the actual team via the Linear team-list tool. Do NOT invent a ## Linear Team heading; use the existing ## Linear Team: resolution that the rest of this command uses. On success read issue.identifier -> CREATED_TICKET_ID, issue.url -> CREATED_TICKET_URL, CREATE_STATUS=created. On MCP error: CREATE_STATUS=failed, CREATE_ERROR=<msg>.
TRACKER == jira: call mcp__mcp-atlassian__jira_create_issue (naming-consistent with the existing mcp__mcp-atlassian__jira_* family used elsewhere in this file). Pass project_key=TICKET_PREFIX, summary=TICKET_TITLE, description=TICKET_BODY, issue_type mapped from TICKET_TYPE (feature -> "Story", bug -> "Bug", task -> "Task"; omit to accept project default if uncertain). On success read the returned issue key -> CREATED_TICKET_ID, construct CREATED_TICKET_URL as <JIRA_BASE_URL>/browse/<CREATED_TICKET_ID>, CREATE_STATUS=created. On MCP error: CREATE_STATUS=failed.
TRACKER has no built-in create branch (forward-looking fall-through): CREATE_STATUS=skipped. Emit one operator line: ticket_driven: create not supported for this tracker - proceeding ad-hoc. Do NOT run any shell command from .agentic/phase0-classifiers.yml as a create operation - the classifier contract is read-only; creation is a write operation outside that contract. This branch is the extension point for trackers not yet integrated: adding a new tracker means adding a create branch above; until then it falls through here. Adding a project-local classifier does NOT constitute a create integration.
LOUD failure (NOT silent): on CREATE_STATUS=failed, emit an operator-visible line mirroring the Writeback Helper's failure line format: tracker-create: '<TICKET_TITLE>' FAILED: <CREATE_ERROR>. Do not block the caller; the caller (the gate) decides: offer mode proceeds ad-hoc AFTER emitting the warning; require mode surfaces and waits.
Run this phase BEFORE Phase 0a-pre. Output is the in-memory
normalized_inputstructure consumed by every later phase. No disk side-effects.
Goal: convert any form of <input> into a deterministic ordered list of {ticket_id, source} entries, an optional freeform_task, and an optional additional_operator_context. Confirm only when classification is ambiguous or destructive.
Fast paths (no confirmation, no operator-visible output beyond the resolution itself).
| Condition | Action |
|---|---|
Invocation is a single token matching ^[A-Z][A-Z0-9_]+-\d+$ AND matches TICKET_PREFIX (when TRACKER ≠ none) | entries=[{ticket_id, source: "literal"}], proceed to Phase 0a-pre. Zero new operator output. |
TRACKER == none AND input is freeform text only (no tickets, no URLs, no images) | entries=[], freeform_task=<input>, proceed. No confirmation prompt. (TRACKER=none has zero ambiguity for freeform — Phase 1's prior freeform prompt is now redundant.) |
Otherwise, classify the input. Built-in classifiers run first, in this order; project-local classifiers (see "Extension point" below) run after for inputs that fall through.
| Input shape | Detection | Resolution |
|---|---|---|
| Bare ticket ID | matches ^[A-Z][A-Z0-9_]+-\d+$ | append {ticket_id, source: "literal"} |
| Comma/space-separated list | tokenize on [,\s]+, each token matches bare-ID regex | append each as source: "list" |
| Jira issue URL | ^https?://[^/]+/browse/([A-Z][A-Z0-9_]+-\d+) | extract group 1, append source: "url:jira-issue" |
| Jira JQL/search URL | host matches JIRA_BASE_URL host AND path is /issues (or /jira/.../issues) AND query contains jql= | URL-decode jql, call mcp__mcp-atlassian__jira_search, paginate up to cap, append each as source: "url:jira-jql" with title |
| Linear issue URL | ^https?://linear\.app/[^/]+/issue/([A-Z][A-Z0-9_]+-\d+) | extract group 1, append source: "url:linear-issue" |
| Linear filter URL | linear.app/<workspace>/view/... or filter query string | call mcp__linear__list_issues with decoded filter, paginate to cap, append source: "url:linear-filter" with title |
| Pasted screenshot | Any image attachment present in the operator's user-message payload (image MIME type or attachment marker indicating an image was uploaded with the invocation) | conductor reads the image directly (Tier 2, multimodal). Extract every distinct [A-Z][A-Z0-9_]+-\d+ substring. Append each as source: "screenshot". Do not spawn an OCR subagent. |
| Freeform residue | any non-matching text after all classifiers consumed their inputs | held aside; see Freeform handling below |
Extension point (project-local classifiers).
If .agentic/phase0-classifiers.yml exists at the project root, load it after Setup and before built-in classifiers run. Built-in classifiers run FIRST; project-local classifiers run only against inputs that fell through (residue not matched by any built-in). Schema:
# .agentic/phase0-classifiers.yml
classifiers:
- source_label: "github-issue" # appended as source: "extension:github-issue"
detect: "^https?://github\\.com/[^/]+/[^/]+/issues/(\\d+)" # regex; capture group 1 is the ID
resolver: "gh issue view $1 --json number,title --jq '{ticket_id: \"GH-\\(.number)\", title: .title}'"
# resolver is either a shell command (string) or an mcp_tool spec object:
# resolver:
# mcp_tool: "mcp__some-server__some-tool"
# args: { id: "$1" }
# response_path: "$.data" # optional; default omitted (read top-level)
- source_label: "asana-task"
detect: "^https?://app\\.asana\\.com/0/\\d+/(\\d+)"
resolver:
mcp_tool: "mcp__asana__get_task"
args: { gid: "$1" }
response_path: "$.data"
Resolution rules:
detect is a regex applied to each fall-through input token/URL.resolver is either a shell command (string) or an MCP tool spec (object with mcp_tool, args, optional response_path). The resolver MUST yield (directly or via response_path extraction) at minimum ticket_id (and optionally title).resolution_notes, no entry produced.source: "extension:<source_label>".Shell-command resolver contract (binding).
resolution_notes but is NOT parsed.{ticket_id: string, title?: string} OR a JSON array of such objects. Any other shape (non-JSON, missing ticket_id, wrong types) is a resolver failure.$1 through $9 correspond to regex capture groups from detect. Substituted values MUST be shell-escaped by wrapping the value in single quotes and replacing every embedded single quote ' with the four-character sequence '\''. Example: a capture value O'Brien's repo is substituted as 'O'\''Brien'\''s repo'. The engineer MUST NOT use unquoted $1 substitution under any circumstance — raw URLs and tracker IDs may contain shell metacharacters (;, &, `, $(), |, newlines) that would otherwise inject commands into the conductor shell."resolver timeout: <source_label>" warning to resolution_notes.MCP-tool resolver contract (binding).
args as the input dict. Capture-group substitution $1-$9 applies to string-typed values inside args by literal string replacement. Shell-escaping does NOT apply (these are tool-call arguments, not shell tokens). The conductor MUST type-check each substituted value against the schema the MCP tool advertises — if the tool expects an integer and substitution produces a non-numeric string, treat as resolver failure and log; do NOT silently coerce.response_path: — a JSONPath-like expression (root $, dot-traversal, optional array index e.g. $.data.items[0]) telling the conductor which sub-object of the tool response carries ticket_id and title. If response_path is omitted, the conductor reads ticket_id/title directly from the top-level response object. If response_path is present but does not resolve (key missing, type mismatch), treat as resolver failure.Security model.
.agentic/phase0-classifiers.yml runs with full conductor privileges: shell-command resolvers execute as the operator's shell user, and MCP-tool resolvers can invoke any MCP server the conductor has access to. Trust level is therefore equivalent to executable code committed to the repository — anyone who can land a change to this file can execute arbitrary commands in any session that runs /ds-implement-ticket against the affected branch. Operators MUST review changes to .agentic/phase0-classifiers.yml whenever pulling an untrusted or unfamiliar branch (collaborator PR, fork, dependabot, agent-authored branch) before invoking /ds-implement-ticket on that branch. The file is project-local by convention and is not signed, sandboxed, or sandbox-enforced. This trust posture matches the rest of the .agentic/ umbrella but is called out explicitly here because Phase 0 runs before any other phase and is therefore the first execution surface a malicious classifier file could exploit.
Rationale for .agentic/phase0-classifiers.yml (over the AGENTS.md ## Tracker extension): the project-local YAML keeps the classifier registry decoupled from tracker config (which is single-tracker by design); supports multiple un-enumerated trackers simultaneously (a project may use Jira primary + GitHub Issues secondary); and matches the .agentic/ convention for project-local agentic state. AGENTS.md ## Tracker remains the single-tracker config; new trackers don't replace it.
Pagination cap. Default 50 issues per URL/filter (combined across pagination). On overflow, prompt: "JQL/filter returned >50 issues; capped at 50. Narrow the query or proceed with the first 50? (narrow / proceed)". On narrow: abort Phase 0. On proceed: keep first 50, log to resolution_notes.
Sanity ceiling. Hard refuse if len(entries) > 200 after all classifiers and pagination. Print: "Phase 0 resolved >200 tickets; refusing as a sanity ceiling. Narrow your input." Exit. This is the ONLY hard refusal in Phase 0.
Deduplication. Dedupe entries[] by ticket_id preserving first-seen order. Record dropped duplicates in resolution_notes.
Freeform handling (mixed-input residue).
| Condition | Action |
|---|---|
entries non-empty AND freeform residue present | Default: route residue to additional_operator_context (attach to every entry's downstream brief). Print residue + entries summary, prompt: "Mixed input detected. Residue: '<first 200 chars>'. Entries: <list>. Attach residue as additional context to all entries, drop, or abort? (attach-to-all / drop / abort) [default: attach-to-all]". On attach-to-all: set additional_operator_context=<residue>. On drop: set additional_operator_context=null, log to resolution_notes. On abort: exit. |
entries empty AND residue AND TRACKER=none | Fast path above already caught this case. |
entries empty AND residue AND TRACKER ≠ none | Confirm: "No tracker IDs detected and TRACKER=<tracker>. Treat input as freeform task (no tracker fetch), or abort? (freeform / abort)". On freeform: set freeform_task=<residue>, entries=[]. On abort: exit. |
entries empty AND no residue | Print: "Phase 0 produced no entries and no freeform task. Re-invoke with a ticket reference or description." Exit. |
Failure handling per classifier.
| Failure | Action |
|---|---|
| Unparseable URL | Treat as freeform residue. Log to resolution_notes. |
| JQL/filter returns 0 results | Print "JQL/filter returned 0 issues." Continue with other inputs. |
| JQL/filter auth failure | Print verbatim error. Abort Phase 0 (no silent freeform fallback — masks credential issues). |
| Screenshot has no detectable IDs | Print "Screenshot contained no <PREFIX>-NNN matches." Continue. |
| Screenshot ID prefix ≠ TICKET_PREFIX | Append anyway with resolution_notes warning. Phase 1 fetch is authoritative. |
| Mixed input where some IDs don't exist in tracker | Phase 0 validates shape, not existence. Phase 1's per-ticket fetch is authoritative. |
| Project-local classifier resolver failure | Treat as Unparseable URL. Log to resolution_notes. |
Confirmation policy. Confirmation runs ONLY in the cases below. All other resolutions proceed silently with a one-line [phase: input-normalization | entries=<N> | freeform=<bool> | extra_context=<bool>] breadcrumb.
| Trigger | Confirmation |
|---|---|
| JQL/filter URL → any N entries | Soft warn + auto-proceed — print resolved IDs + titles in a one-per-line list, do NOT prompt; emit resolution_notes entry. The operator wrote the JQL deliberately; Phase 0a batch triage already presents a per-ticket summary downstream; "as autonomously as possible" is the stated goal. (Aligned with the operator-enumerated >5 row below.) |
| Screenshot → any N entries | Yes — OCR is approximate, print extracted IDs, (proceed / abort) |
| Mixed input with freeform residue | Yes — (attach-to-all / drop / abort), default attach-to-all |
| Cap hit (>50 from JQL/filter) | Yes — (narrow / proceed) |
| No IDs + TRACKER ≠ none + freeform residue | Yes — (freeform / abort) |
| Operator-enumerated sources (literal IDs, comma/space lists, single issue URLs, mixed bare-IDs+issue-URLs) producing >5 entries | Soft warn + auto-proceed — print loud warning enumerating all resolved IDs in a one-per-line list, do NOT prompt; emit resolution_notes entry. (Threshold of 5 is chosen because a single visual scan can verify ≤5 IDs; >5 deserves an explicit list so the operator catches typos, but the operator already enumerated each one — confirming would violate "as autonomously as possible".) |
| All other operator-enumerated cases (≤5 IDs, single URL, fully unambiguous) | No confirmation. Proceed silently. |
| Sanity ceiling (>200) | Refused (no prompt; hard exit). |
Tier: Tier 2 (conductor-direct, including screenshot read and resolver execution).
Collision-awareness backstop (consume-time). When Phase 0 resolves ticket entries, the conductor reads each ticket body for a ## Scope boundary section (written by the Create Helper collision pre-check). If present, carry it into the architect brief and engineer execution contract. If absent AND the tracker supports queries, run the same in-flight overlap scan the Create Helper runs before the architect spawns; on overlap, surface the boundary to the operator and append it to the architect brief. Best-effort, never blocks Phase 0 - this catches human-filed tickets that skipped the create-time pre-check.
Trigger: invocation carries goal_mode=open_goal. Mutually exclusive with Phase 0a-pre/Phase 0a - skip both when this fires; fall through unmodified when it does not.
Read .agentic/batch-state.json if present.
Absent, or mode != "open_goal": → Fresh init.
mode == "open_goal": classify via termination_reason first (authoritative when non-null, regardless of status); fall back to status sub-partition only when termination_reason == null.
A. termination_reason non-null (6 of 7 buckets; resolved without consulting status):
cap_reached_iterations | cap_reached_wallclock → TERMINAL; print:
A prior open-goal loop already terminated (reason: <termination_reason>, iteration <N>/<max_iterations>). Starting fresh clears this state. To continue this goal instead, re-invoke with max_iterations and/or max_wallclock_min set HIGHER than the current values (max_iterations=<X>, max_wallclock_min=<Y>). Confirm: fresh-start (delete + reinit) or raise-caps (continue from iteration <N+1>)? (fresh / raise-caps)
fresh and raise-caps.blocked → TERMINAL, fresh ONLY (raise-caps can't unblock a stuck Skeptic loop); prompt adds: "To resume the specific blocked iteration's stuck work instead, use the ordinary per-ticket Resume check against that iteration's own branch - this phase does not do that."goal_met → TERMINAL, fresh ONLY (nothing to raise).paused_stale_pace | paused_operator_request → RESUMABLE.B. termination_reason == null (7th bucket; sub-partitioned on status, exhaustively):
status in {paused, interrupted} → RESUMABLE.status == "active" → apply Contract A's existing per-write session_id-mismatch determination to this READ (same 4-way logic Contract A uses to gate every batch-state.json WRITE, applied here as read-time classification):
session_id non-empty and matches current session → RESUMABLE (same-session continuation; covers crash-mid-advance re-invoked same session).session_id non-empty, differs, AND last_updated older than 10 min → RESUMABLE, treated as implicitly interrupted (mirrors Phase 0a-pre "status=active AND last_updated>10min → implicit interrupt"). Covers crash-mid-advance surviving into a later session.session_id non-empty, differs, AND last_updated within last 10 min → REFUSE, verbatim Contract C message: "Another batch session is active for this project root (session_id=<X>, last_updated=<Y>). Wait for it to finish, or kill it and re-invoke." Exit. (live-foreign-session; closes the null+active Contract-C bypass.)session_id null/absent (legacy) → force-takeover prompt verbatim (Phase 0a-pre): "WARNING: another session (session_id=<X>, last_updated=<Y>) may still be active. Force takeover? (yes/no). Identify the live session via .agentic/loop-state.json last_updated." yes → RESUMABLE; no → exit/wait.status == "complete" → TERMINAL, fresh ONLY (safe default; unexpected/legacy combo).status == "stalled" → TERMINAL, fresh ONLY (same rationale).status → TERMINAL, fresh ONLY (safe default).Completeness statement: every (termination_reason, status) pair lands in exactly one of {Fresh init, RESUMABLE, raise-caps-or-fresh (terminal-cap bucket), refuse}. Bucket A resolves 6 of 7 termination_reason values without consulting status. Bucket B exhaustively covers the 7th value (null) across all 5 named status enum values + explicit catch-all; status==active within bucket B is itself exhaustively partitioned by Contract A's 4-way session_id/staleness logic. No pair unclassified.
batch-state.json → Fresh init. (force-takeover "no" exits/waits, does NOT go fresh.)max_iterations/max_wallclock_min strictly greater than on-disk: "raise-caps requires re-invoking with max_iterations and/or max_wallclock_min set higher than the existing values (current: max_iterations=<X>, max_wallclock_min=<Y>). Re-invoke with a higher value, or choose fresh." On success: Contract A write (update, NO Contract C - update not create) setting raised cap(s), termination_reason:null, status:"active" → Advance to next iteration (idempotency-checked).status:"active"; do NOT reset iteration → Advance to next iteration (idempotency-checked).goal_condition divergence (unchanged): read from disk on any resume, never re-parsed; differing invocation value prints one-line "on-disk value governs" warning (mirrors Phase 0a-pre GENUINE-divergence pattern), continues.Read the last entry in tickets[] (if any):
tickets[] empty OR last entry status == "complete": no next-iteration entry yet → apply the IDENTICAL Contract A+B write Phase 12a "On no trigger, GOAL_MET false" performs (increment open_goal.iteration, append pending entry) - reused by reference.status is "pending" or "in_progress": a next-iteration entry was ALREADY appended (most likely by Phase 12a's advance-write interrupted before Phase 1 - the crash-mid-advance scenario). Do NOT increment iteration or append again - use the existing entry as-is. Prevents double-advance (silent skip/dupe of an iteration).Either way, fall through to Phase 1 for the iteration corresponding to the last tickets[] entry.
Validation (refuse before Phase 1 on failure):
goal_condition missing → refuse: "goal_mode=open_goal requires goal_condition to be declared. Re-invoke with goal_condition set." Exit.max_iterations or max_wallclock_min missing/non-positive → refuse verbatim (trigger-catalog.md Hard-stop rule 5): "goal_mode=open_goal requires max_iterations and max_wallclock_min to be declared - no unbounded default is permitted. Re-invoke with both fields set." Exit.dry_run, if present, must be literal true/false; absent defaults to false. No refusal on absence.Contract C check (before any write): apply the broadened Contract C check above (Fresh init is one of the three triggering create-paths) - refuse verbatim if batch-state.json is active/foreign-session/recent. Exit on refusal.
On successful validation (Contract A fresh write):
.agentic/batch-state.json: mode:"open_goal", batch_id:"open-goal-<ISO8601>-<4hex>", wallclock_cap_min:<max_wallclock_min>, wallclock_started_at:now, tickets:[], open_goal:{active:true, goal_condition:<string>, iteration:1, max_iterations:<int>, risk_declared:null, termination_reason:null, dry_run:<bool>}.loop-state.json NOT touched here - initialized normally at Phase 6 loop init exactly as any ordinary iteration (no open-goal fields).[phase: open-goal-init | goal_condition="<condition>" | max_iterations=<N> | max_wallclock_min=<M> | dry_run=<bool>].Off-by-one note (Minor): at init, iteration=1 but tickets=[] (len 0) - SOLE momentary exception to iteration==len(tickets[]), closed the moment Phase 1 of iteration 1 appends the first synthetic entry. From Phase 1 of iteration 1 onward, the invariant holds continuously.
Per-iteration ticket lifecycle. Each iteration's synthetic tickets[] entry (ticket_id:"<goal-slug>-iter-N", cluster_id:"open-goal") follows the SAME transition-write pattern ordinary batch tickets use: pending → in_progress at Phase 1 start, in_progress → complete at Phase 12, or → blocked via "Batch-mode escalation routing" (Phase 6). Every transition applies Contract A + Contract B.
Interaction with top-level "Resume check (before setup)". That check reads loop-state.json before Phase 0, independent of this phase. A mid-iteration interrupted resume jumps to that iteration's resume entry point; Phase 0a-open-goal is never re-entered that session. Step 0 fires only on a normal Phase 0 pass reaching goal_mode=open_goal.
Run this phase BEFORE the per-ticket Resume check below. This is the composition anchor: batch-level resume picks the ticket cursor first; the per-ticket Resume check then runs unmodified scoped to that ticket's branch and
loop-state.json.
Trigger: Phase 0 normalization produced ≥ 2 entries (same trigger as Phase 0a). Skip otherwise.
Single-ticket wallclock carve-out. Single-entry invocations bypass this phase entirely - no .agentic/batch-state.json is read or created - EXCEPT when max_wallclock_min is declared on a single-entry invocation with no goal_mode. In that case: apply the Contract C refusal check (broadened per the Contract C definition above) ONLY - do NOT also run the separate N=1 foreign-batch warning first; both checks share the identical trigger (active + different session + ≤10min), so the softer warning first would be dead code (Contract C refusal always overrides any yes/proceed). This differs from the ordinary N=1 path, which never creates batch-state and never needs Contract C. On success (Contract A fresh write): create .agentic/batch-state.json{mode:"single_ticket_capped", tickets:[{ticket_id:<the one entry>, status:"pending", cluster_id:null, depends_on:[]}], wallclock_cap_min:<max_wallclock_min>, wallclock_started_at:now}. This is the ONLY N=1 path that creates batch-state.json.
Read .agentic/batch-state.json if present. Apply the decision table below.
batch-state.json state | Action |
|---|---|
| absent | Skip Phase 0a-pre. Fall through to the existing per-ticket Resume check, then Setup, then Phase 0a (which initializes batch-state.json). |
status=complete | Print: "Prior batch complete; clearing." Delete the file. Fall through to the existing per-ticket Resume check. |
status=stalled | Print stalled summary (tickets + reasons). Prompt: resume / fresh / abandon. On abandon: delete file and exit. On fresh: delete file and fall through. On resume: apply re-plan migration (below) and pick next pending ticket. |
status=paused | Print: "Batch paused at operator request: [last_summary]." Prompt: resume / fresh. On fresh: delete file and fall through. On resume: apply re-plan migration and pick next pending ticket. |
status=interrupted | Print: "Batch interrupted (reason: [interrupt_reason]). N completed, M pending/blocked." Prompt: resume / fresh. On fresh: delete file and fall through. On resume: apply re-plan migration and pick next pending ticket. |
status=active AND last_updated > 10 min ago | Treat as implicit interrupt. Same prompt as interrupted row. |
status=active AND last_updated ≤ 10 min AND session_id matches current | Silent re-entry resume (rare; e.g. /ds-implement-ticket re-invoked within the same session). Pick next pending ticket from tickets[]. |
status=active AND last_updated ≤ 10 min AND (session_id differs OR session_id is null/absent) | If Phase 0 produced ≥ 2 entries: refuse with the verbatim Contract C message. If Phase 0 produced exactly 1 entry: see "N=1 foreign-batch warning" below; this row does not apply (Phase 0a-pre runs only when Phase 0 produced ≥ 2 entries). For N≥2 force-takeover prompts: print "WARNING: another session (session_id=<X>, last_updated=<Y>) may still be active. Force takeover? (yes/no). Identify the live session via .agentic/loop-state.json last_updated." and require explicit operator confirmation. |
| Parse failure | Print warning. Prompt: delete-and-fresh / abort. On abort: exit. On delete-and-fresh: delete file and fall through. |
Inconsistent pair (batch-state.json says active, loop-state.json says interrupted) | Trust the non-active file. If both are stale-active (>10 min), treat as implicit interrupt for both. |
Move ordering hazard (resume case). On resume, batch-state.json.tickets[] is the authoritative ticket cursor and supersedes any Phase 0 output produced in the resuming session. If the operator re-supplied input, compare Phase 0 entries[] against on-disk tickets[]:
batch-state.json.tickets[] as the cursor.WARNING: resumed batch tickets[] = [<list>] contain ticket IDs not present in this invocation's Phase 0 entries[] = [<list>].
The on-disk batch state takes precedence on resume. Continue resuming the prior batch, or abandon resume and use the new input?
(continue-resume / abandon-resume-and-use-new-input)
On continue-resume: discard Phase 0 output, use batch-state.json.tickets[]. On abandon-resume-and-use-new-input: delete batch-state.json and re-run Phase 0a from the new entries.
Resume composition rule (binding). If Phase 0a-pre confirms resume of an active batch, it sets the in-memory ticket cursor to the next pending ticket from tickets[] BEFORE falling through to the existing per-ticket Resume check. The per-ticket Resume check then runs UNMODIFIED but scoped to the picked ticket's branch and loop-state.json. The two state mechanisms compose: batch resume picks the ticket; per-ticket resume picks the phase within that ticket. They have non-overlapping scopes.
Re-plan migration on resume. When the operator confirms resume of any non-active batch state (stalled, paused, interrupted, or stale-active treated as interrupted):
git fetch origin.tickets[] with status pending or blocked: re-fetch the tracker record. If the ticket has been merged elsewhere (per tracker status, or per gh pr list --state merged --head <branch> returning a non-empty result), append a replan_log entry {ts, action: "drop_merged", ticket_id, detail} and set the ticket's status to skipped_already_merged.replan_count >= 2: count replan_log entries with action: "investigator_rerun"; if the count is >= 2, spawn a real background investigator (including the functional-duplicate brief); otherwise run Level 1 only (conductor-direct). Append the replan_log entry {ts, action: "investigator_rerun", ticket_id: null, detail: "replan #N"} BEFORE spawning the investigator when it fires. Map the resulting lanes back to the surviving tickets' cluster_id and depends_on fields (array order); deferred or in-progress-excluded tickets discovered during re-plan are surfaced to the operator and excluded from tickets[].session_id gate) and Contract B (replan_log[] read-merge-write preservation). See "Batch state contracts" below.status back to active. Preserve wallclock_started_at from the prior batch (the wallclock cap is per-batch lifetime, not per-session - a batch resumed in a later session continues counting against the original wallclock_started_at).Emit breadcrumb: [phase: batch-resume | tickets_remaining=K].
Trigger: Phase 0 normalization produced ≥ 2 entries.
Skip: Phase 0 produced exactly 1 entry. Mixed-form inputs that Phase 0 normalized down to a single entry count as single-entry and skip Phase 0a.
Flow:
Run the /ds-ticket-triage planning algorithm (Phases 1-3) conductor-orchestrated. Phase 0a feeds its OWN already-normalized entries[] directly into triage Phase 1 - triage Phase 0 is NOT re-run (entries are already normalized).
Phase 1 (metadata fetch, conductor-direct, soft-fail): for each entry, fetch priority, status, story_points, labels, components, assignee, and issuelinks from the tracker (same per-ticket fetch as /ds-ticket-triage Phase 1). Soft-fail per ticket (mark fetch_failed: true and proceed). Detect terminal: true (Done/Cancelled) and in_progress: true (active workflow state) per the /ds-ticket-triage Phase 1 rules.
Phase 2a (DAG + cycle handling, conductor-direct): build the dependency graph from blocks/is-blocked-by links, detect cycles (break at lowest-confidence link, defer both with cycle_warning: true). External deps noted but not used for lane assignment.
Phase 2b conflict-surface analysis: Level 1 is always conductor-direct (shared component/label overlap check). Level 2 applies when len(entries) <= 20: spawn ONE real background investigator with the full /ds-ticket-triage Phase 2b brief, including the functional-duplicate detection task (bar: "a reasonable engineer would implement them with exactly the same change"). When len(entries) > 20: set HEURISTIC_ONLY=true and proceed WITHOUT prompting - rationale: the batch was already committed via Phase 0, and prompting mid-initialization wastes operator context.
Phase 3 (Rules 1-4, conductor-direct): distribute surviving tickets across lanes using the /ds-ticket-triage Phase 3 consume-and-remainder pipeline. Lane cap is fixed at 3 on this path (--lanes override is not available for the /ds-implement-ticket integration path).
The result is an in-memory triage_result containing:
{lanes[], deferred[], in_progress_excluded[], functional_duplicates[], conflict_warnings[], heuristic_only}.
Surface triage findings to the operator BEFORE building tickets[]. Present a structured summary covering:
Functional duplicate warnings (when functional_duplicates[] is non-empty): for each pair, print the ticket IDs and the one-sentence reason. Prompt the operator PER PAIR (after all lane assignments are known, since Phase 3 has already run):
Functional duplicate detected: <A> + <B> - <summary>
Both tickets appear to describe the same functional work.
Action: (defer-first / defer-second / keep-both)
On defer-first: add ticket A to deferred[], remove it from its lane. On defer-second: add ticket B to deferred[], remove it from its lane. On keep-both: no change. Do NOT recompute the lane distribution after a defer choice - surgically remove the deferred ticket from its lane only.
Deferred tickets (from Phase 3 Rule 1 + any operator-deferred duplicates): list each with its reason.
In-progress tickets (from Phase 1): list each. These are excluded from tickets[] and kickoff.
HEURISTIC_ONLY notice (when HEURISTIC_ONLY=true): "Conflict analysis: Level 1 only (component/label overlap; >20 tickets, investigator pass skipped). Functional-duplicate detection was also skipped."
After surfacing, map ONLY the lane-assigned tickets to tickets[] (deferred and in-progress-excluded tickets are NOT written to tickets[]).
Map in ARRAY ORDER: lane 1 first, lane 2 next, lane 3 last. Within each lane, chains are topo-sorted (blockers first); parallel tickets within the same lane are sorted priority-descending then ticket_id-ascending. Each entry:
status: "pending"cluster_id: "lane-N" (where N is the lane number)depends_on: ["<prev-ticket-id>"] (chain) or [] (parallel lane head or independent)No merge_order field. Array position is the execution cursor.
Emit breadcrumb: [phase: batch-triage | triage_algorithm=ticket-triage-phases-1-3 | N tickets | lanes=K | lane_cap=3 | deferred=P | excluded_in_progress=Q | heuristic_only=<bool>].
Initialize .agentic/batch-state.json (persistent batch cursor). First apply the Contract C concurrent-batch refusal: if the file already exists with status=active, a different session_id, and last_updated within the last 10 minutes, REFUSE with the verbatim Contract C message and exit. Otherwise, write the initial skeleton:
schema_version: 1session_id: <current>batch_id: "<first ticket's TICKET_PREFIX>-batch-<ISO8601>-<4hex>"status: "active"tickets[]: triage-derived executable cursor; contains only lane-assigned tickets (deferred and in-progress-excluded tickets are not included); in array order as described in step 2 abovewallclock_started_at: now, wallclock_cap_min: <env AGENTIC_BATCH_MAX_WALLCLOCK_MIN or 90>replan_log: []created_at: now, updated_at: nowAtomic tmp+rename. Apply Contract A on the write (this is a fresh write so no prior session_id; the gate effectively passes).
Conductor iterates through tickets[] in array order (tickets[] contains only lane-assigned executable tickets; deferred and in-progress-excluded tickets were surfaced in step 2 and are not present), running existing per-ticket phases (1 → 12) for each ticket. Per-ticket transition writes to batch-state.json (each via Contract A + Contract B):
status: "pending" → "in_progress", set started_at, update updated_at.status: "in_progress" → "complete", set ended_at, last_summary, pr_number, branch.status → "blocked" with detail in last_summary.status → "skipped_already_merged" with replan_log append.Persistent batch state lives in .agentic/batch-state.json. See Phase 0a-pre for the resume protocol.
Before any architect spawn, check for an existing Brief, snapshot qa.md for Elevated tickets, and handle the on-resume Brief migration for tickets predating the qa_criteria requirement.
Slug derivation: convert the ticket title to kebab-case and strip any ticket-ID prefix
(e.g. AE-123 Add user login becomes add-user-login).
Check (either condition satisfies):
docs/planning/<slug>.md, OR.agentic/brief-session.json exists with status: complete AND brief_path matching
the ticket slug.If found:
brief_path = docs/planning/<slug>.md in the architect execution contract (Phase 3).brief_source: operator to the Skeptic-on-Brief gate; use the operator-confirmed
Skeptic variant (completeness-only review per content/commands/ds-brief.md Section 6)..agentic/brief-session.json confirms brief_source: operator, set operator_brief_injectionable: true to signal Phase 3 that the Brief's committed constraints should be injected into the architect spawn brief (see Phase 3 "Pre-authored Brief injection").If not found: proceed normally. The promotion gate in Phase 3b determines whether a Brief is required based on the unit count from the orchestration-planner.
After risk has been classified, if the current ticket is Elevated, snapshot any existing .agentic/qa.md to a per-ticket snapshot file. Trivial invocations skip this step entirely (preserves bit-for-bit-identical guarantee for Trivial single-ticket invocations - no .agentic/qa.md.snapshot-* file is produced).
Snapshot rules:
.agentic/qa.md does not exist: skip silently (nothing to snapshot)..agentic/qa.md exists and .agentic/qa.md.snapshot-<ticket_id> does NOT already exist: copy .agentic/qa.md to .agentic/qa.md.snapshot-<ticket_id> via atomic write (write to .agentic/qa.md.snapshot-<ticket_id>.tmp, then rename)..agentic/qa.md.snapshot-<ticket_id> already exists (e.g., on resume of a paused or interrupted ticket): preserve the existing snapshot. Do not overwrite. The original snapshot represents the qa.md state at the start of this ticket's first run.The snapshot is consumed at Phase 11b by wrap-ticket to compute the diff between the snapshot and the working-tree .agentic/qa.md, surfacing qa.md additions made during this ticket. Phase 12 cleanup removes the snapshot file. The snapshot path is gitignored under the existing .agentic/ umbrella; no .gitignore change is needed.
When Phase 0a-pre or the per-ticket Resume check detects an in-flight ticket whose Brief lacks the qa_criteria field (because the ticket was started before the qa_criteria requirement was rolled out), apply this migration before spawning any worker:
Probe architect plan. If the architect plan (referenced from the Brief or stored alongside it) contains a qa_criteria block, the conductor authors a retroactive Brief amendment appending the architect's qa_criteria block verbatim into the Brief. Proceed normally.
If neither has qa_criteria (legitimate transition ticket), surface the operator prompt verbatim:
WARNING: this ticket's Brief and architect plan predate the qa_criteria requirement. Options:
(a) provide a qa_criteria block now (paste YAML)
(b) one-time bypass for this transition ticket (skip QA for this ticket only)
Choose (a/b).
On (a): the operator pastes the YAML; conductor injects it into the Brief and proceeds.
On (b): conductor records a one-time bypass marker for THIS ticket only (in-context, scoped to this resume) and proceeds with QA skipped. The bypass does NOT extend to future tickets.
New invocations (no in-flight state) hard-fail per architect plan. Fresh /ds-implement-ticket invocations on Elevated tickets without a qa_criteria block in the Brief or architect plan emit a Critical Skeptic finding on the architect plan; the conductor does not proceed past Phase 3 until the architect plan supplies the block. The on-resume bypass option is exclusively for tickets that started before this requirement existed.
(Setup has already resolved TRACKER. Execute exactly one of the sub-sections below.)
Iteration: Phase 1 runs once per entry in normalized_input.entries. The current [TICKET_ID] refers to entry.ticket_id. When normalized_input.entries is empty AND normalized_input.freeform_task is set, only the TRACKER is none sub-section executes, with freeform_task as the description. When entries is non-empty, the TRACKER is none sub-section is skipped regardless of TRACKER value.
When normalized_input.additional_operator_context is non-null, append it verbatim to every entry's downstream architect (Phase 3) and engineer (Phase 5) brief, prefixed with "Additional operator context (applied to all entries):". This routes mixed-input residue into the per-entry brief without dropping operator intent.
