Chart - decision-map discovery (pre-capture)

Read workflow.md for routing and the mode dispatch table. It routes to exactly one mode reference per invocation (chart / work / briefing-reopen / re-entry); status mode and the safety recap stay inline there. Native prompts, adaptive traces, and the full flag tables: references/examples.md.

Takes one unshaped idea that is too big for a single capture session and wrapped in unknowns, and finds the route by resolving one decision at a time until the effort can be captured as one or more specs. Unit of work is a decision (D-ID), not a build task. Chart never writes a spec and never sets ready; output is a briefing handed to /flow-next:capture.

Role: discovery coordinator (inline skill - keep blocking questions reachable). Host agent owns grounding, interpretation, frontier judgment, evidence-route dispatch, prototype presentation, attended consent, re-charting, and the terminal verdict. flowctl owns atomic create/claim/resolve/scope/briefing/store mutations.

Preamble

CRITICAL: flowctl is BUNDLED - NOT installed globally. which flowctl will fail (expected). Define once; subsequent blocks (here and in workflow.md) use $FLOWCTL:

FLOWCTL="${CODEX_HOME:-$HOME/.codex}/scripts/flowctl"
[ -x "$FLOWCTL" ] || FLOWCTL="<plugin-root>/scripts/flowctl"   # <plugin-root> = the directory two levels above this skill's SKILL.md file (the harness gave you that file's absolute path when the skill loaded); substitute it literally
[ -x "$FLOWCTL" ] || FLOWCTL=".flow/bin/flowctl"

Inline skill (no context: fork) - keeps plain-text numbered prompt available for read-back consent and attended routes. Subagents cannot call plain-text numbered prompts. For read-only scouts use spawn_agent with agent_type: explorer (or the host's generic read-only dispatch with Edit/Write disallowed when Explore is unavailable). On portable hosts without plain-text numbered prompt, fall back to a plain-text numbered prompt with a final Other - type your own answer option.

Prompt-first contract

Natural language is the primary control surface. Free-form steering of outcome, known facts, next move, skips, reversals, prototype reactions, and briefing intent reaches the same guarded flowctl operations. Flags and exact subcommands are documented for automation, scripting, and debugging - they are never required vocabulary for humans.

On every invocation:

1. Infer the intended mode and operation from $ARGUMENTS + conversation. Ask the user via plain text. Render the options below as a numbered list 1. … N., followed by a final option N+1. Other — type your own answer. Print the question, then the numbered list, then stop and wait for the user's next message before continuing. Parse the reply as: a bare number 1–N+1 → that option; the literal text of an option label → that option; free text after Other → custom answer.

2. Ask a plain-text numbered prompt only when two interpretations would materially change the chart, cost, or consent boundary.

3. Read back any state-changing interpretation before persisting.

4. Never edit chart Markdown or decision sidecars by hand - always $FLOWCTL chart ....

Modes (disambiguate by argument)

Invocation shape	Mode	Behavior
free-form idea / "chart out ..."	chart	Bounded Grounding Snapshot -> name Outcome + visible frontier + parked unknowns + cost -> consent read-back -> chart create --initial-map-file (resolve nothing)
<chart-id> or "work the next decision on ..."	work	Re-anchor Outcome + Notes -> chart frontier sole selection input -> claim one D-ID -> evidence route -> resolve/scope/release -> re-chart
<chart-id> --decision <n> / explicit D-ID	work (pinned)	Same as work; human selects the decision if it is still open/unblocked/unclaimed
<chart-id> --status / "what's left to decide"	status	Render map + frontier + remaining attended cost; resolve nothing
stored tracker URL / locator	re-enter	Probe chart locate (local ledger only); degrade if unavailable - see workflow

Plain-language equivalents reach the same modes (R17).

Verdict grammar (exact)

Every work invocation ends with exactly one greppable line and nothing after it:

CHART_VERDICT=<RESOLVED|BLOCKED|NEEDS_HUMAN|COMPLETE|NO_WORK> chart=<id> decision=<D> reason="<one line>"

Verdict	When
RESOLVED	One D-ID closed via resolve or out-of-scope; frontier recomputed
BLOCKED	Claim conflict, graph/store refusal, or no actionable path without human repair
NEEDS_HUMAN	Stored attendance:attended decision reached by an unattended driver - no answer write
COMPLETE	Chart briefable (no open decisions, no parked questions) after this tick, or briefing emitted
NO_WORK	Empty frontier, skip-chart (no consequential unknowns), status-only, or chart mode finished without resolving

Chart mode and status mode also print one terminal line so host /loop//goal drivers can parse uniformly (decision=- when no D-ID was claimed).

Unattended driver signals (any one): FLOW_RALPH=1, non-empty REVIEW_RECEIPT_PATH, non-empty FLOW_AUTONOMOUS, or the host is driving without a human present. Interactive terminal sessions are attended.

Decision types = evidence routes

Type	Attendance	Resolves by
research	unattended	Scout reads docs / primary sources / knowledge bases; returns a fact
probe	unattended	Measure or reproduce against the real system
eval	unattended	Bake-off / benchmark on real fixtures; winner + why
prototype	attended	Throwaway artefact + human reaction (hard gate)
interview	attended	Conversation, one question at a time (default for product judgment)
task	explicit at create	Manual work that only unblocks a decision (not implementation smuggling)

Attendance is stored and validated by flowctl for five types; task requires --attendance attended|unattended. Cost estimates and unattended gates read the stored field, never prose.

Invariants (hard)

• One invocation = one D-ID = one claim = one verdict. Independent unattended frontier decisions fan out only as separate invocations. No batch or mixed-result grammar.
• Charting resolves nothing. Chart mode ends after map + first decision records + cost exist.
• flowctl chart frontier is the sole selection input for work mode (optional human pin still must appear on that frontier).
• Claim before any work. Refuse double-claim; release with note on stop; crash leaves claim visible.
• Attended hard gate. Unattended driver + attendance:attended -> persist no answer, release or leave claim per workflow, terminate NEEDS_HUMAN.
• Prototype lifecycle. Create/import one scoped throwaway artefact -> chart attach-asset while open -> present exact safe reference/revision -> record human reaction -> resolve/supersede. Interruption leaves asset + open D-ID resumable. Never rebuild, never infer approval, never promote prototype code into implementation.
• No nameable destination -> STOP. Chart's premise is destination known, route unknown. A theme or direction ("make X more Y") has no end state to state as an Outcome and no boundary to rule anything out of scope. Offer narrowing to one effort with a stateable end state, or /flow-next:prospect when the real ask is which effort to pick; create nothing.
• No consequential unknowns -> STOP. Recommend /flow-next:capture or the smaller direct route; create nothing.
• Over chart.maxDecisions (default 12). Offer narrow Outcome or split first. Pass --force-size --reason only after explicit warning + consent read-back.
• Provenance lanes stay separate. Grounding facts get citations under ## Notes and never become D-IDs or acceptance-criterion trailing tags ([user] / [paraphrase] / [inferred] / [strategy:*]). fn-148 closed STOPPED with no verdict - include NO verified/inferred fact grammar.
• Unsafe evidence by reference. Never embed secrets or literal destructive shell command strings in chart artefacts; store a safe redacted summary + approved path/HTTPS reference. Describe such operations in prose only.
• Context discipline. Status/frontier navigation loads compact metadata only. Full decision bodies and assets load only for the selected D-ID or briefing.
• Skill never edits Open Questions, edges, or sharpened decisions directly. Use park/remove/wire/resolve --sharpen-file / create --initial-map-file.

Flags (automation only - not required vocabulary)

Documented for scripting; the full flag table, the human-intent -> flowctl map, and conversational equivalents live in references/examples.md. Only --status (status mode) and --decision <n> (pin a D-ID for work mode) affect routing; --json is available on every flowctl chart subcommand.

Workflow

Execute workflow.md:

0. Route - parse args, probe locator for URL-like selectors, choose mode.
1. Mode dispatch - read only the routed mode's reference:
   • Chart mode - Grounding Snapshot (ordered) -> read-back Outcome/frontier/cost -> create or stop.
   • Work mode - re-anchor -> frontier -> claim -> evidence route -> resolve/scope/release -> sharpen -> re-chart -> one verdict; supersession when steering says the direction changed.
   • Briefing handoff / reopen - when briefable, propose clusters, confirm, briefing --proposal-file, hand to capture.
2. Status mode - compact show + frontier + cost; no mutations (inline in workflow.md).

Forbidden

• Writing under .flow/specs/ or mutating a spec's ready flag.
• Answering attended decisions without the human side of the exchange.
• Turning imported background into fabricated resolved D-IDs or acceptance-criterion tags.
• Shipping verified/inferred fact grammar (fn-148 did not land guidance).
• Precomputing a complete discovery route or treating adaptive traces as mandatory phases.
• Embedding literal destructive shell command strings or realistic secrets in chart bodies, answers, briefings, or this skill's examples.
• Silent claim expiry, silent supersession cascade, or silent prototype-to-implementation promotion.
• Setting context: fork (blocking questions must stay reachable).
