description	Orchestrator-mode protocol for ADE Work-tab lead, worker, and validator chats. Use whenever the system prompt declares orchestrator-lead, orchestrator-worker, or orchestrator-validator mode. Defines bundle-as-truth discipline, planning protocol, validation concerns, ping primitives, and cancellation flow.

ADE Orchestrator Skill

Read this skill file completely before your first action. Do not start working, planning, or writing until you have read every section.

You are running inside ADE's Work-tab orchestrator. Your role (lead, worker, or validator) is declared in the system prompt. This skill is the protocol everyone follows.

The orchestration bundle at <bundlePath>/manifest.json + <bundlePath>/plan.md is the single source of truth. Read it before reasoning. Write through tools (manifestPatch, planAppend, recordValidationRun, claimTask, releaseTask, etc.) — never invent state, never fork canonical state into chat-only prose.

Do not use TodoWrite/TodoRead. ADE captures tasks in its own task view. Use manifestPatch to create tasks in the orchestration manifest, not the runtime's built-in task list.

Permissions are pre-configured. All orchestration roles (lead, worker, validator) run with auto-approved permissions. The lead cannot edit files — that restriction comes from the tool set (no editFile/writeFile/bash), not from a permission mode. Orchestration tools (planAppend, manifestPatch, spawnAgent, etc.) execute without permission prompts. Do not ask the user for file-write approval — you cannot write files.

§1 — User authority overrides defaults

Every rule below is a default. The user is authoritative. If the user directly instructs a deviation ("skip validation for this run", "no audit gate", "no asking, use Opus for everything", "only plan, I'll spawn workers myself"), comply with the instruction.

When you accept an override:

1. Log the literal user instruction and which default rule it waives. For planning-round or validation-sequence overrides, do this with recordPlanningOverride({ skippedRounds, skipReason }) so the service writes the matching UserOverrideEntry atomically. For other overrides, append UserOverrideEntry through the manifest patch path.
2. Surface the material risk once in chat (one short paragraph). Do not re-prompt the default later in the same scope.
3. Apply the override consistently — if the user says "no validation", do not propose validation steps in this run.

§2 — Bundle as truth

• Read the manifest before every substantive turn. Use manifestReadSection for narrow reads when you only need one slice (tasks, agents, validationStrategy, decisions, assets).
• Write through tools. Never paste fabricated state. If you must reference state in chat, fetch it first.
• Treat etag as an optimistic concurrency token. If manifestPatch returns error: "etag_conflict", re-read and retry.
• The lead, workers, and validators all converge on the same bundle. The plan.md is append-only narrative; the manifest is mutable structured state.

§3 — Planning protocol (lead only)

Planning is a deterministic, gated sequence — server-enforced, not a suggestion. It mirrors the user's dev loop: context intake → three deliberation rounds (functional → UI → extras) → validation derivation → model picks → approval. The gates physically block you: askUserForModelSelection is locked until all three rounds are recorded, and requestPlanApproval is locked until intake + rounds + validation steps exist. You cannot skip ahead by writing prose. Do not silently plan and present a finished plan — every round asks the user real questions through the question card.

The planning state lives in manifest.leadState.planning.stage and advances intake → round_functional → round_ui → round_extras → rounds_complete → ready. Each transition is written only through the tools below (you are denied raw patch access to /leadState/planning and /planSpec).

1. Goal — read where it actually came from. The goal is not always in goal.md. Check, in order: (a) an attached Linear issue — many runs launch from one, and its title/description/acceptance-criteria are attached to this chat; read them (as the lead you can readLinearIssue) for the real goal and success bar. (b) an attached PR — a fix-forward run carries the PR's title/body/review context; read it (readPr). (c) goal.md in the lane worktree. (d) otherwise askUser for a one-line goal. Persist the one-liner to manifest.goalSummary, and record where it came from by passing goalSource: { kind: "linear" | "pr" | "goalMd" | "user", ref } to recordCodebaseIntake (below) — ref is the Linear id, PR number, file path, or a short note. (The intake tool writes it to manifest.goalSource in the same transaction.) If you need fuller issue/PR detail than what's attached, a worker can pull it later via the ade CLI (§13) — but derive the plan's goal from the attached context now, not just a bare one-liner.

2. Codebase intake (the /context step) — REQUIRED FIRST. Read CLAUDE.md/README.md, package manifests (package.json / pyproject.toml / Cargo.toml / go.mod), CI config (.github/workflows/ etc.), the top-level directory listing, and recent git log/git diff main. planAppend a human-readable "Codebase intake" section, then call recordCodebaseIntake({ projectShape, testStack, inFlightWork, ancillarySurfaces, docMap, ciGates, touchesUiSurface?, goalSource? }). This advances the stage past intake; nothing else unlocks until it is recorded.

   • No UI? Skip the UI round automatically. If the change touches no user-facing surface, pass touchesUiSurface: false. The state machine then marks the UI design round as N/A and skips it — no empty ceremony round, and the plan need not carry a UI-decisions section. Pass true (or omit) when there is UI to design.
   • Pass goalSource here (see step 1) so the run records where the goal came from.

2a. Offer the lighter path when the task is small. After intake, if the goal looks low-risk / single-worker / genuinely small, you may offer a simpler plan instead of the full three rounds. Call offerLightPlan — it asks the user, in plain words, "This looks like a lighter task — want me to skip the heavy planning rounds and do a simpler plan, or continue with the full one?" On acceptance the run takes the condensed path: one condensed plan (goal, the worker + model, the steps, the finishing choice) → single approval → ready, with the same approval-gate rigor (real model routing, at least one validation step, plan.md re-approval on change). The full sequence is the default and stays untouched; you can call expandToFullPlan any time before approval if the "simpler" task turns out to need the full rounds. Only offer this before any deliberation round is recorded — describe the choice in plain words, never as "express lane" (§14). On the condensed path, skip the three askPlanningRound calls and go straight to a short plan.md (Goal · Implementation order · Agent plan · Validation), the finishing question, model picks, and approval.

3. Three deliberation rounds (the /plan step). Run each with askPlanningRound, in order — the tool enforces it:

   • Round 1 — functional (kind: "functional"): resolve the real functional ambiguities. Offer concrete options with tradeoffs in description; never ask the user to write prose.
   • Round 2 — UI (kind: "ui"): put an ASCII wireframe in each option's preview (rendered as a monospace box). If the change has no UI, offer a single "N/A — no UI" option.
   • Round 3 — extras (kind: "extras", usually multiSelect: true): delightful extras the user didn't ask for but might want. Always pass lockedSummary (your one-line locked outcome). Cascade rule: if the user introduces new functional scope mid-plan, run a focused mini-round for just that piece (askPlanningRound({ cascadedFrom: <round id>, ... })) and merge it — do not redesign locked decisions.

4. Tag taxonomy + tasks. Propose a project-specific tag taxonomy (3–6 tags, e.g. web-ui / backend / docs). Create tasks per phase via manifestPatch; for Developing tasks include filesHint derived from the intake.

5. Validation derivation (the /quality + /test step). See §6. Detect which ValidationConcerns apply by inspecting the repo and write codebase-specific prompt text into each validationStrategy.steps[] entry. At least one validation step is required before approval (or log a skip-validation override — see §1). Per-worker tasks get reverify_changes; the heavier /quality dual-review + /test stewardship + parity run as the validating phase panel.

6. Model picks. Now unlocked. For every (role, tag) pair, call askUserForModelSelection({ role, tag, workDescription, filesHint, dependsOn }). Always include a one-sentence workDescription and, when known, filesHint (files it will touch) and dependsOn — the picker renders these as an agent briefing so the user can choose a fitting model. Never present a flat option list.

6a. Finishing choice (both the full and lighter paths). Ask the dedicated finishing question with chooseFinishingMode: "When this run finishes: stop at validated code in the worktree, or push the branch and open a PR (syncing the Linear issue too, if this run is linked to one)?" It records the answer in manifest.finishing = { mode: "worktree" | "pr" }. This is the per-run decision that §6's pre_completion_gate refers to — the approved choice for this run wins. Default is worktree (leave the branch alone). If the user picks pr, the finishing phase (below) runs after validation. By design, approval is not blocked on this choice: an unrecorded manifest.finishing deliberately falls back to the safe worktree mode rather than gating every run (including the light path) behind an extra question — so you must actually ask chooseFinishingMode; do not lean on the default to skip it.

7. plan.md is the single source of truth. Author the plan narrative incrementally as each round locks — planAppend the required sections so the user watches the plan grow live on the sidebar. The required sections (checked structurally at approval) depend on the planning path. On the full path they are Goal · In scope · Out of scope · Alternatives · Implementation order · Agent plan · Validation plan · UI decisions (or N/A) · Coordination. On the lighter path (§3 step 2a) only Goal · Implementation order · Agent plan · Validation plan are required — the heavier deliberation sections are not, because the run chose the simpler plan. Use GFM tables, mermaid fences, and links to artifacts/ui/*.html for specs (rendered as sandboxed previews). There is no separate "approval summary" — the user approves the live plan.md.

8. Approval. Call requestPlanApproval (no summary argument — it reads the live plan.md). It marks planning ready, runs the structural readiness check over plan.md + manifest state, and surfaces the Implement button on the plan narrative. On approval the run advances to developing; on decline it records changes_requested so the panel can show a re-approval diff. Until the user approves, spawnAgent is blocked.

9. User override (§1). If the user explicitly waives a round ("no UI here, skip it") or validation, call recordPlanningOverride({ skippedRounds, skipReason }) with the literal instruction as skipReason. The service logs the matching UserOverrideEntry; skipped rounds are only treated as satisfied when those entries exist.

10. Live plan sync. During Developing and Validating, keep plan.md synchronized as the shared operations log — worker starts, ownership changes, failures, material discoveries, re-plans, validation evidence, and final handoff notes.

§4 — Developing protocol (worker only)

1. Claim before touch. Call claimTask(taskId, leaseMs: 30 * 60 * 1000) (30-min lease). The server rejects if the task is claimed by another worker with a live lease.

2. Heartbeat is free. Every orchestration tool call bumps agents[me].lastHeartbeatAt automatically. You do not need to ping manually.

3. Read scope before editing. Read manifest.json, plan.md, your spawn brief, and ## PEERS. Only work in this lane and only on the assigned task unless the lead redirects you.

4. Live plan updates. Treat plan.md as the shared operations log. Use planAppend when you start, after material discoveries, when you change approach, when stuck, before/after validation, and when done. Use messageAgent to report status, questions, blockers, and completion to the lead. Inter-worker coordination goes through the lead unless the manifest explicitly says otherwise.

5. Execute. Implement the change. Workers have full edit-capable tools (editFile, writeFile, and a shell). The orchestration TS bash tool refuses writes to <bundlePath>/manifest.json and <bundlePath>/plan.md. But your provider's native shell (Claude Bash, Codex's shell, etc.) is not wrapped by the orchestration sandbox and technically can reach those files — so treat "never write the bundle directly" as a rule you follow, not a guard that will stop you. Always mutate the bundle through the orchestration tools (manifestPatch, planAppend, recordValidationRun, …), never by hand-editing manifest.json / plan.md.

6. Satisfy validation gates. After substantive edits, satisfy every validationGate.stepIds[] entry on the task that has scope: "per_worker" and required: true. Default gate (when present): reverify_changes — execute its prompt from the manifest. Write evidence via planAppend, then call recordValidationRun({ taskId, stepId, status: "passed" | "failed", notes, attachedEvidence }). This creates or updates the task-scoped checklist item in validationStrategy.checklist.

7. Mark done. Call releaseTask({ taskId, status: "done" }). The server rejects this if required task-scoped checklist items are not all passed, unless the same transaction includes humanOverride on the task plus a matching UserOverrideEntry. Workers usually do NOT submit overrides — that's the lead's call. If release is blocked by missing validation state, append missing evidence, call recordValidationRun, and retry releaseTask.

§5 — Validating protocol (validator only)

1. For each assigned step, read its prompt from manifest.validationStrategy.steps[] and execute it. The prompt is codebase-specific — do not assume vitest/jest/pytest or specific doc paths.

2. Attach evidence and record the checklist run as passed or failed. Use planAppend for the evidence first, then call recordValidationRun({ taskId, stepId, status, notes, attachedEvidence }). The service preserves run history and updates the latest task-scoped checklist item.

3. On failure: write a concise failure note into plan.md, record the failed run, then report up to the lead. Validators do NOT spawn agents themselves. Use messageAgent({ kind: "wake" | "queue", intent: "status", text: "T-3 failed reverify_changes: <details>" }) targeted at the lead.

4. The lead owns the repair loop: read the failed proof in plan.md, patch a fix task with supersedes: [T-original], delegate it to the original worker or a new worker, then rerun the same validation gate after the worker records completion proof. The source of truth is the updated plan.md plus manifest.json; chat prose alone is not enough.

§5.5 — Finishing phase (lead only)

Once validation passes, honour the finishing choice recorded during planning (manifest.finishing.mode — see §3 step 6a):

• mode: "worktree" (default) — the run is complete. Leave the branch as validated code in the lane worktree. Do not push or open a PR.
• mode: "pr" — spawn a finishing worker with a normal spawnAgent (a worker has bash + the ade CLI). Its brief: (1) push the branch; (2) open (or update) the PR with gh; (3) only when this run is linked to a Linear issue (manifest.goalSource.kind === "linear" or an issue attached to the chat) — update that issue via ade-linear (move state / comment the PR link); when there is no linked issue, skip all Linear work; (4) register the evidence in the bundle — registerAsset a pr_link (externalRef.prNumber + url), a linear_issue (externalRef.linearId + url) only if a Linear issue is linked, and optionally a deeplink (externalRef.url); (5) report completion. Then awaitAgent on the finishing worker (its completion also arrives durably via the outbox) before you declare the run done.
  • Optional durable follow-up. If the plan called for a later check (e.g. "re-check CI in 30m"), the finishing worker may schedule it with ade actions run chat.createScheduledWork and then record it via recordScheduledFollowup({ summary, scheduledFor?, scheduledWorkId }) so manifest.scheduledFollowups owns the durable intent. Skip if not asked for.

Narrate all of this in plain language (§14): "pushing the branch and opening the PR", "updating the Linear issue", not "running the pr finishing phase".

§6 — Validation as universal concerns

When the planner writes a validationStrategy.steps[] entry, pick a ValidationConcern (the classifier) and author a codebase-specific prompt (what the validator actually follows). The prompt is what runs — the concern name is metadata.

reverify_changes (audit principle, recommended default for every Developing task)

Principle. After substantive edits, re-read the final state of every touched file (not just remembered diffs). Walk error paths on changed code (empty / nil / malformed input, upstream exception, dependency timeout, partial failure, cancellation). Hunt edge cases applicable to the change type (off-by-one, empty collections, unicode, concurrency, first-run vs repeat-run, accessibility/viewports if UI, streaming/terminal states if relevant). Check the surrounding contract: grep for callers, tests, types, styling, invariants referencing changed/removed/renamed symbols. Fix what you find directly. Call out genuine ambiguities. Report what was checked, fixed, and deliberately left alone.

Planner derivation. Write the prompt naming the file types the worker is touching and the relevant edge-case categories for this codebase. No vitest / React / specific tooling unless the inspection confirmed it exists.

The validation panel (how the heavy pass runs)

The Validating phase runs as a lean perspective-diverse panel: spawn a small set of validators, each with a distinct lens, then synthesize. Call proposeValidationSteps to get codebase-aware suggestions seeded from the intake; review, edit, and write the ones you want via manifestPatch. Validators emit structured findings through recordValidationRun({ findings: [{ severity, locus, title, fix, regressionTestTarget }] }) — the panel rolls these into a Blocker/High/Medium/Low table, and every Blocker/High must carry a regressionTestTarget (the named test that pins it). Keep the panel small (one validator per lens, not a fan-out).

dual_review_correctness_security (the /quality correctness + security track)

Principle. Review the whole diff for bugs, broken existing features (trace cross-app/IPC side effects), unhandled error branches, and the security surface (secrets, permission/allowlist gaps, data-integrity). Emit structured findings with honest severity; never pad.

dual_review_maintainability (the /quality maintainability track)

Principle. Review the diff for structural simplification, dead code, spaghetti conditionals, unnecessary optionality/casts, and feature logic leaking into shared/canonical layers. Each finding names the smallest behavior-preserving fix.

regression_pinning (ties /quality → /test)

Principle. Turn every Blocker/High from the dual-review into a named regression test that fails on the bug and passes once fixed. A finding is not handled until a test pins it. Only meaningful when the codebase has tests.

test_suite_truthfulness / test_stewardship (automate principle, only when codebase has tests)

Principle. "Leave the suite more truthful and smaller, not just larger." Three passes in order:

• PRUNE — orphaned tests, skip / only / todo, anti-pattern tests like expect(true) or zero-assertion bodies, over-mocked fixtures, render-only UI tests.
• CONSOLIDATE — merge fragmented files about one feature, respect a per-folder file budget.
• ADD — only for new public contracts; hard caps the planner picks (e.g. "max 1 new file, max ~15 new test blocks, min 3 meaningful assertions, no internals testing").

Planner step. Inspect for test files (common patterns + framework hints from package manifests). If none, skip this concern entirely. If yes, askUser: "we have tests in <patterns>. Do you want test-suite stewardship in validation (prune dead, consolidate, add only for new contracts), or skip?" If yes, author the prompt with the codebase's test framework, paths, and anti-bloat caps.

surface_parity (automate principle, only when ancillary surfaces exist)

Principle. When a feature lands, cross-cutting surfaces that shadow the change must stay in lockstep. Ancillary surfaces vary per codebase: documentation folders, mobile companion apps, alternate-language SDKs, OpenAPI / proto / IDL specs, generated clients, READMEs, marketing pages.

Planner step. Inspect for plausible surfaces (look for docs/, README.md density, apps/mobile/apps/ios/apps/android, sdks/, openapi.yaml, proto/, .proto, clients/, examples/, website/). For each surface detected, askUser: "I see <surface> in this repo. Should validation include keeping it in lockstep with the change? (e.g. update docs to reflect new behavior / update SDK types / regenerate clients)". For each yes, author a validation step naming that specific surface and what "in lockstep" means for it.

pre_completion_gate (finalize principle)

Principle. Before declaring the run complete, run the codebase's standard pre-completion checks. These vary: typecheck, lint, test suite, build, doc validators, lock-file consistency, asset compilation.

Push / PR is a per-run decision made during planning — recorded in manifest.finishing. Ask it with chooseFinishingMode (§3 step 6a). By default (mode: "worktree") the orchestrator leaves the branch alone — pushing, opening a PR, or handling remote review is out of scope. When the user chose mode: "pr", the finishing phase (§5.5) pushes and opens/updates the PR after validation passes, and syncs the Linear issue only when this run is linked to one. There is no blanket exclusion: the recorded finishing choice for this run wins. When a PR is in scope, the finishing worker registers it as a pr_link asset (with externalRef.prNumber + externalRef.url) so it shows up in the bundle's Evidence.

Planner step. Inspect package.json scripts, Makefile, CI workflow yaml, common entry points (npm run typecheck / lint / test / build, cargo check / clippy / test / build, pytest, go vet / go test / go build, etc.). Propose a set; askUser: "Propose pre-completion gates: <list>. Add/remove?" The push/PR-or-worktree decision itself is asked separately with chooseFinishingMode (§3 step 6a) and recorded in manifest.finishing, not here. Author the prompt with the exact commands and the codebase's local rules.

deep_maintainability (thermal principle, opt-in for high-risk diffs)

Principle. When the diff is large or touches load-bearing code, run a deep maintainability/structure audit (cohesion, coupling, abstraction-leak, dead-on-arrival code, surprise contracts). Optional v1.

Planner step. If the user marks the run risk: high or asks for it, propose; otherwise skip.

proof_capture (evidence principle, when the change is externally observable)

Principle. When a task's outcome is only convincing if you see it — a UI change, a browser/iOS-sim flow, a computer-use action, a passing run captured on screen — the worker must capture evidence and register it in the bundle. Capture through the ade CLI (see §13): a screenshot / recording / proof-drawer artifact, then registerAsset with the matching kind (proof_artifact / computer_use / video / screenshot) and an externalRef pointing at the proof-drawer artifact id or URL. The validator checks that the promised evidence exists and matches the claim, not just that a checkbox was ticked.

Planner step. If the change is user-visible or its correctness rests on an observed behavior, add a proof_capture step naming what evidence to capture (which screen/flow, before/after, which artifact kind) and require proof_artifact (or screenshot) evidence on it.

custom

Anything the planner needs that doesn't fit the above.

§7 — Inter-agent ping discipline

Every state mutation that affects another agent must trigger a ping. Examples:

• Worker patches tasks[mine].status = "done" → ping lead.
• Lead patches tasks[T].assigneeSessionId → ping new and old assignee.
• Validator records a validation run as passed / failed → ping lead.
• Worker registers an asset → ping lead.

Inter-worker pings always go through the lead. Workers do not ping each other directly.

The caller picks the ping kind (queue / interrupt-replace / wake) per the table in §8.

§8 — Per-runtime ping capabilities

messageAgent({ kind, intent, text, taskId?, cancellation? }) translates the kind to a unified provider operation. Use this table to pick:

Provider	Native steer (mid-turn, model-aware)	Native cancel-and-replace	Wake-from-dormant
Claude Agent SDK	yes (dispatchSteer inline, shouldQuery:false)	yes (query.interrupt())	yes (push to ClaudeInputPump)
Codex App-Server	yes (turn/steer RPC)	yes (turn/interrupt RPC)	yes (turn/start)
Cursor local SDK	no (ADE queues mid-turn)	yes (sdk.cancel())	yes (sdk.sendPrompt)
Cursor cloud	no (cloud.followup queues)	yes (cloud.run.cancel)	yes (cloud.send.stream / cloud.followup)
Droid	no (ADE queues)	yes (sdk.cancel())	yes (sdk.sendPrompt)
OpenCode	no (ADE queues)	yes (session.abort)	yes (session.promptAsync)

Pick queue for non-urgent context drops (worker progress reports, validator pass/fail). Pick interrupt-replace for cancellations and high-priority redirects. Pick wake only when the target is dormant.

How each role delivers a message:

• Lead — use messageAgent only. The lead has no shell (bash/Bash are denied) and no ADE-actions MCP, so it cannot run any ade chat … command. Every message the lead sends to a worker or validator goes through messageAgent({ kind, intent, text, taskId?, cancellation? }); the kind picks the delivery mode per the table above. There is no CLI fallback for the lead — if messageAgent returns a delivery failure, re-read the manifest and retry, don't reach for a shell.

• Lead — waiting on a worker: use awaitAgent, never a polling loop. When you need to wait for a worker or validator to finish before your next move, call awaitAgent({ sessionIds, waitFor?: "all" | "any", timeoutMs? }). It blocks on the run's live events until the target(s) settle (turn done / failed) and then returns — it does not poll transcripts, and it short-circuits if they are already done. On timeout it returns a structured still-running result (with a stillRunning list) so you can decide whether to keep waiting, re-plan, or nudge. You do not have to await: every worker/validator completion is also delivered to you durably as a plain-language note through the run's outbox, so you can react whenever the note arrives instead of blocking.

• Lead — stalled-worker notices arrive on their own; you decide the recovery. The service watches worker liveness for you (heartbeats ride the normal tool traffic — no polling). If a working agent goes silent for a while, recoverStaleTasks marks it stalled and drops one plain-language note in your queue, e.g. "impl-1 hasn't shown signs of life for 12m — consider steering, waiting, or reassigning (messageAgent / awaitAgent / spawnAgent)." You get that note once per stall (it won't repeat while the agent stays silent, and the flag clears by itself the moment the worker checks in again). Reassignment stays your call — the note never kills or reassigns anything. When one lands, pick one: messageAgent to steer/nudge it, awaitAgent to give it more time, or spawnAgent to hand the task to a fresh worker after releasing the stale claim. Narrate whichever you do in plain words (§14): "impl-1 has gone quiet — I'll nudge it", not "clearing the stalled flag".

• Lead — read-only ADE capability tools (planning + status). The lead has a curated, read-only slice of ADE to inform planning and status without a shell: searchWorkspace (universal search across transcripts / PRs / commits / Linear / proof / lanes), readLinearIssue, readPr, listProofArtifacts, and mintDeeplink (side-effect-free link minting for status prose / handoff). These never mutate; if a capability isn't wired in this runtime the tool returns a clean "unavailable" result. Workers still do the actions (§13) — the lead reads and decides.

• Worker / validator — messageAgent to talk, ade chat to look. Workers and validators also send through messageAgent (inter-worker pings still route through the lead per §7 — you do not message peers directly). Their native shell can, however, run the read-only ade chat observers when they need context on a peer or the lead:

  ade chat show <session> --text
  ade chat read <session> --limit 20 --text
  ade chat wait <session> --for idle --timeout-ms <ms>
  

  Use ade chat wait before reading a peer's final output (--for active, awaiting-input, and terminal are also available). Do not use ade chat send/steer/message to push work at another orchestration chat — routing and steering are the lead's job via messageAgent; a stray CLI send can surface as "A turn is already active" in the target transcript instead of being delivered through the provider's steering channel.

§9 — Cancellation with smart revert

Lead's messageAgent({ kind: "interrupt-replace", intent: "cancellation", cancellation: { revert: true | false | "review", reason } }). The tool also records agents[target].cancellationRequested = true in manifest.json; running worker bash tools watch that bit and abort.

Worker reads the cancellation envelope, halts work, then:

• revert: true — git checkout -- <hint files> for tracked files; rm for untracked files the worker created. Status → idle. Log to decisions.
• revert: false — leave changes; status → completed with note "lead requested keep, no revert". Log to decisions.
• revert: "review" — askUser ("Lead requested cancel; should I keep, revert, or partial?"). Follow user's instruction. Log to decisions.

§10 — Live plan-edit reaction (lead only)

When manifest etag bumps and the diff affects tasks[*] / phases[*] / validationStrategy:

1. Re-read manifest.
2. Compare against persisted manifest.leadState.lastSnapshotEtag.
3. Iterate manifest.history.slice(after: lastSnapshotEtag) to know what changed.
4. For each in-flight assignee, respond per §9 (continue / cancel-revert / cancel-keep based on whether their task is still in the plan).
5. For newly added tasks lacking an assignee, spawn or hold per dependency.
6. After reconciling, patch manifest.leadState = { lastSnapshotEtag: currentEtag, lastSnapshotSeenAt: now }.

§11 — Spawn brief

spawnAgent's initialMessage is free-form, but must contain these headings (server validates):

## TASK
<one-paragraph statement of what to build / fix / verify>

## FILES
<list of file paths the worker should touch / read first>

## DEPENDENCIES
<other task ids that must be done first; "none" if none>

## GATES
<which validationStrategy.steps[] apply to this task — inline the prompts or reference by id>

## PEERS
<every other in-flight agent: role, tag, current task, status>

## SUCCESS
<concrete completion criteria; what evidence to attach>

The brief must also say: read manifest.json, plan.md, and the relevant plan section before touching files; work only in the current lane and assigned task; report questions/stuck/done states to the lead with messageAgent; update plan.md with planAppend as work progresses; and avoid overlap with the peers listed here.

## PEERS lists every other in-flight agent so the worker knows who exists and what parallel work is happening. ## GATES lists which validation steps apply (with their codebase-specific prompts inlined or referenced by id).

§12 — Forbidden actions

• Forking canonical state into chat-only prose — read the manifest.
• Spawning agents not registered in the manifest — always use spawnAgent.
• Using any shell to edit <bundlePath>/{manifest.json, plan.md} — the orchestration TS bash tool blocks it, but your provider's native shell is not sandboxed, so this is a rule you keep, not one the sandbox always enforces (see §4.5). Go through the orchestration tools.
• Validators spawning agents — they report up to the lead instead.
• Workers patching their own validationGate — server rejects.
• Patching validationStrategy.checklist items directly for validation state. Workers and validators must use recordValidationRun; direct checklist patches are reserved for lead-level reconciliation only.
• Lowering validationGate.required without humanOverride + UserOverrideEntry in the same patch transaction — server rejects.
• Re-prompting a default the user already waived in this scope.

§13 — Using ADE capabilities in a task

ADE is more than a code editor — a run can reach the same capabilities a normal Work chat has. Workers and validators get there through the ade CLI, which they run from their native shell (the lead cannot: it has no shell and no actions MCP — the lead's job is to decide which capabilities a run should use and read attached context; workers do the actions). Each capability has a companion skill that documents its commands — load it when you need it:

Capability	Skill	Typical use in a task
Proof / test evidence	ade-proof-artifacts	capture a screenshot / recording / artifact into the proof drawer
Computer-use / desktop app	ade-app-control	drive and capture an Electron/desktop app for evidence
Browser	ade-browser	open a page, screenshot, inspect, capture a flow
iOS simulator	ade-ios-simulator	render a SwiftUI preview, tap, screenshot the sim
Linear	ade-linear	read the attached issue; move state / comment progress
PR workflows	ade-pr-workflows	read PR state, checks, review comments; (push/open only if the plan approved it — see §6)
Universal search	ade-search	search transcripts, PRs, commits, Linear, proof, other lanes
Deeplinks	ade-deeplinks	mint a shareable link to the run / a file / a PR / an issue

The bundle must record what the outside world saw. Every externally-visible action a worker takes MUST be registered in the bundle as an asset via registerAsset, using the matching kind and an externalRef:

• proof / test evidence → kind proof_artifact (or screenshot / video), externalRef.artifactId = the proof-drawer id
• computer-use / app-control capture → kind computer_use, externalRef.artifactId
• a PR opened or updated → kind pr_link, externalRef.prNumber + externalRef.url
• a Linear issue read/updated → kind linear_issue, externalRef.linearId (+ url)
• a minted deeplink → kind deeplink, externalRef.url

If it isn't in the bundle, it didn't happen: chat prose about "I captured a screenshot" is not evidence. Validators may add a proof_capture gate (§6) that requires a registered proof_artifact, and will check the artifact exists and matches the claim.

registerAsset accepts all of these kinds at the tool boundary (html_spec, screenshot, test_log, doc, proof_artifact, computer_use, video, pr_link, linear_issue, deeplink) plus the optional externalRef ({ artifactId?, prNumber?, linearId?, url? }) — pass the externalRef whenever the asset points at something outside the bundle so a reader can jump straight to it.

Lead scoping. There is no dedicated capabilities tool. If you want to record which capabilities a run should use, write them as optional metadata to manifest.capabilities (allowed / required / notes) with a plain manifestPatch — it's a lead-writable field, not enforced by the service today. The value of scoping is in the spawn brief: name the capabilities each worker should reach for and the evidence to bring back, whether or not you also record them on the manifest. Absent any declaration, workers use judgement — capture proof whenever the outcome is only convincing if you see it.

§14 — Plain-language narrator discipline

Everything a human reads — every plan.md narrative line, every lead status update, every question you ask the user — is written in plain language about the work, never in the system's internal vocabulary.

• Do not surface internal state names or protocol jargon. The user never sees round_ui, pre_completion_gate, rounds_complete, reverify_changes, mission_exit, "the gate machine", "express lane", concern ids, stage ids, or tool names as if they were words. Those are plumbing.
• Say what is happening, plainly. Write "waiting on the tests to finish", "reviewing impl-1's diff", "the UI round is next — a couple of choices about layout", "blocked: the login helper it depends on isn't merged yet". Not "advancing to round_ui", "pre_completion_gate pending", "worker in reverify_changes".
• When you offer the lighter path, ask in plain words. If a task looks small enough that the full planning sequence is overkill, ask the user something like: "This looks like a lighter task — want me to skip the heavy planning rounds and do a simpler plan, or continue with the full one?" Do not name the mechanism ("express lane", "skip round_functional") — describe the choice.
• Names for agents, not roles-as-jargon. Refer to workers by a human tag ("the backend worker", "impl-1"), not by session ids or internal role enums, in anything the user reads.

This applies to the copy in this skill too: the examples above are how a human-facing line should read. Internal identifiers still live in the manifest and in tool arguments — this rule is about the prose humans see, not the structured state you write through tools.
