flow-next-capture

name	flow-next-capture
description	Synthesize the current conversation context into a flow-next spec at `.flow/specs/<spec-id>.md` via `flowctl spec create + spec set-plan` — agent-native, source-tagged, with mandatory read-back before write. Triggers on /flow-next:capture, "capture spec", "lock down what we discussed", "make a spec from this conversation", "convert conversation to spec". Optional `mode:autofix` token runs without questions and requires `--yes` to commit. Optional `--rewrite <spec-id>` overwrites an existing spec; `--from-compacted-ok` overrides the compaction-detection refusal; `--override-strategy` proceeds despite a contradiction with an active STRATEGY.md track (and prompts to record the override as a decision).

/flow-next:capture — agent-native conversation → spec

A free-form discussion (or a /flow-next:prospect survivor) frequently produces enough material for a complete spec, but stops short of the formal flowctl spec create + spec set-plan heredoc documented in CLAUDE.md. Without an explicit synthesis step, that context decays — the next session loses the conversation, the spec never lands, and the user re-explains the same idea to /flow-next:plan.

This skill IS the synthesis. The host agent (Claude Code / Codex / Droid) extracts the recent user turns, drafts a CLAUDE.md-shaped spec with per-line source tags ([user] / [paraphrase] / [inferred]), shows the full draft back via AskUserQuestion, and only then writes the spec via existing flowctl plumbing. There is no Python synthesizer, no codex / copilot subprocess, no fast-model classifier. The host agent is already an LLM and does the work directly.

flowctl provides only thin spec plumbing (spec create, spec set-plan, optional spec set-branch, memory search for duplicate detection). No new flowctl subcommands.

Read workflow.md for the full phase-by-phase execution. Read phases.md for the must-ask cases lookup, source-tag taxonomy, confidence tiers, and forbidden-behaviors list.

Preamble

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

FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"
[ -x "$FLOWCTL" ] || FLOWCTL=".flow/bin/flowctl"

Inline skill (no context: fork) — AskUserQuestion must stay reachable across phases. Subagents can't call blocking question tools (Claude Code issues #12890, #34592). Phase 0 (duplicate detection) and Phase 4 (read-back loop) both require user choice in interactive mode. (sync-codex.sh rewrites this to a plain-text numbered prompt in the Codex mirror.)

Mode Detection

Parse $ARGUMENTS for the literal token mode:autofix and the flags --rewrite <spec-id>, --from-compacted-ok, --yes, --override-strategy. Strip recognized tokens; whatever remains is treated as freeform context (ignored — the conversation is the input, not $ARGUMENTS).

RAW_ARGS="$ARGUMENTS"
MODE="interactive"
REWRITE_TARGET=""
FROM_COMPACTED_OK=0
COMMIT_YES=0
OVERRIDE_STRATEGY=0

# Mode token
if [[ "$RAW_ARGS" == *"mode:autofix"* ]]; then
  MODE="autofix"
  RAW_ARGS="${RAW_ARGS//mode:autofix/}"
fi

# --rewrite <id>
if [[ "$RAW_ARGS" =~ --rewrite[[:space:]]+([^[:space:]]+) ]]; then
  REWRITE_TARGET="${BASH_REMATCH[1]}"
  RAW_ARGS="${RAW_ARGS//--rewrite ${REWRITE_TARGET}/}"
fi

# --from-compacted-ok
if [[ "$RAW_ARGS" == *"--from-compacted-ok"* ]]; then
  FROM_COMPACTED_OK=1
  RAW_ARGS="${RAW_ARGS//--from-compacted-ok/}"
fi

# --yes (autofix commit gate)
if [[ "$RAW_ARGS" == *"--yes"* ]]; then
  COMMIT_YES=1
  RAW_ARGS="${RAW_ARGS//--yes/}"

  RAW_ARGS="${RAW_ARGS//--override-strategy/}"
fi

Mode	When	Behavior
Interactive (default)	User is at the terminal	Phase 0 asks on duplicate detection; Phase 3 asks on must-ask ambiguities; Phase 4 read-back via blocking-question tool — write only on approve
Autofix (mode:autofix)	Batch usage from another skill / scripted invocation	No user questions. Phase 0 hard-errors on duplicates / compaction without explicit overrides. Phase 3 must-ask cases hard-error (autofix can't ask). Phase 4 Writes the full draft once (the Write render is the emission) + prints the summary tally to stdout. Writes to .flow/ ONLY when --yes is also passed; without --yes, exit 0 with "draft written; rerun with --yes to commit"

Autofix mode rules

• No user questions. Never call the blocking-question tool.
• Phase 0 hard-errors: duplicate detected → list overlapping spec IDs to stderr, exit 2 unless --rewrite <id> was passed; compaction detected → exit 2 unless --from-compacted-ok was passed.
• Phase 3 must-ask hard-errors: ambiguous title / untestable acceptance / scope-conflict-with-existing-spec → exit 2 with which case fired and why. Autofix cannot resolve must-ask cases.
• Phase 4 single emission, no .flow/ write. Full draft Written once to the §4.1 draft file (the Write render is the full emission — all sections + R-IDs); summary payload ([inferred] tally + 8+ acceptance suggestion if applicable) printed to stdout. Without --yes, exit 0 with the "rerun with --yes" hint. With --yes, proceed to Phase 5 write.
• Phase 5 commits identically to interactive once it runs.
• Readiness never written. The mark-ready write (workflow.md §5.9) is interactive-consent-only; autofix prints a footer suggestion at most (and only when readiness is adopted, no tracker.readyState, and the spec was written). The --rewrite readiness reset (§5.3) still runs — it is idempotent plumbing, not a consent question.

Ralph-block (R13) — runs first, before everything else

/flow-next:capture requires conversation context + user confirmation. Autonomous loops have neither. Hard-error with exit 2 when running under Ralph.

if [[ -n "${REVIEW_RECEIPT_PATH:-}" || "${FLOW_RALPH:-}" == "1" ]]; then
  echo "Error: /flow-next:capture requires conversation context + a user at the terminal; not compatible with Ralph mode (REVIEW_RECEIPT_PATH or FLOW_RALPH detected)." >&2
  exit 2
fi

No env-var opt-in. Ralph never decides direction.

Interaction Principles (interactive mode only)

In autofix mode, skip user questions entirely and apply the rules above.

In interactive mode:

• Ask one question at a time via AskUserQuestion (call ToolSearch with select:AskUserQuestion first if its schema isn't loaded). Fall back to numbered options in plain text only if the tool is unreachable or errors. Never silently skip the question.
• Lead with the recommended option and a one-sentence rationale, followed by a confidence marker — [high] / [judgment-call] / [your-call]. The body carries the recommendation; option labels stay neutral so the user isn't anchored on the option text itself. (See phases.md §Confidence tiers.)
• Prefer multiple choice when natural options exist (Phase 0 duplicate decision; Phase 4 approve/edit/abort).
• Do not ask the user for facts they already gave you in conversation — Phase 1 extracts evidence first; Phase 3 asks only on the three hard-error must-ask cases plus genuinely missing context that can't be inferred.

The goal is automated synthesis with human oversight on judgment calls — not a question for every section.

Forbidden behaviors (R10)

• Tech-stack mentions the user did not state. "Needs persistence" is fine; "uses PostgreSQL" needs the user to have said PostgreSQL. Defer technology choices to /flow-next:plan (spec-kit convention — capture writes intent, plan writes implementation).
• Inventing acceptance criteria not in conversation. Every acceptance criterion must be source-tagged; pure [inferred] criteria must surface at Phase 4 read-back so the user can reject them.
• Code snippets or specific file paths in the spec body. Those belong in /flow-next:plan task specs after research lands. Capture's output is a high-level spec, not an implementation guide.
• Silent overwrite of an existing spec. Idempotency requires --rewrite <spec-id> (R8). Without it, Phase 0 conflict-detection branches into extend / supersede / proceed-anyway.
• Auto-splitting a spec that has 8+ acceptance criteria. Phase 4 surfaces the option to split; the user decides. Never auto-action a split.
• Setting context: fork — blocking-question tools must stay reachable.
• Calling flowctl spec create before Phase 4 approval. Phase 5 is the only write phase.
• Writing glossary terms without consent, or in autofix mode. Term-adds require the Phase 4.2 Glossary? approval; autofix prints suggestions only (--yes consents to the spec write, not to vocabulary changes). The gate is husk-aware (glossary list --json total_terms > 0) — seeding an empty glossary is /flow-next:prime's job, never capture's.
• Using git add -A from this skill. When committing the new spec, stage only the JSON sidecar (.flow/specs/<id>.json post-1.0; .flow/epics/<id>.json on alias-mode 0.x repos that haven't migrated yet) + .flow/specs/<id>.md (and .flow/meta.json if the next-id counter mutated). Other working-tree changes are not capture's concern.

Pre-check: local setup version

Same pattern as /flow-next:audit and /flow-next:prospect — non-blocking notice when .flow/meta.json setup_version lags the plugin version:

if [[ -f .flow/meta.json ]]; then
  SETUP_VER=$(jq -r '.setup_version // empty' .flow/meta.json 2>/dev/null)
  PLUGIN_JSON="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/.claude-plugin/plugin.json"
  PLUGIN_VER=$(jq -r '.version' "$PLUGIN_JSON" 2>/dev/null || echo "unknown")
  if [[ -n "$SETUP_VER" && "$PLUGIN_VER" != "unknown" && "$SETUP_VER" != "$PLUGIN_VER" ]]; then
    echo "Plugin updated to v${PLUGIN_VER}. Run /flow-next:setup to refresh local scripts (current: v${SETUP_VER})." >&2
  fi
fi

Workflow

Execute the phases in workflow.md in order:

0. Pre-flight — duplicate detection (scan .flow/specs/ + .flow/epics/ for legacy alias-mode repos + flowctl memory search on extracted keywords); compaction detection (scan transcript for truncation markers); idempotency (refuse silent overwrite without --rewrite).
1. Extract conversation evidence — build a verbatim ## Conversation Evidence block FIRST (raw quotes from recent user turns, capped ~30 lines). Spec sections refer to it by line, not from agent memory.
2. Source-tagged synthesis — draft each section with per-line tags ([user] / [paraphrase] / [inferred]). Apply the canonical template at plugins/flow-next/templates/spec.md (per R17 — cross-link, never re-embed the section list inline). At runtime the template is resolved via the 4-tier discovery cascade — first match wins: <repo_root>/SPEC.md → <repo_root>/spec.md → .flow/templates/spec.md → bundled ${PLUGIN_ROOT}/templates/spec.md. The bundled file is the canonical source of truth; earlier tiers are user-customized overrides. Route explicit biz-context signals (nine SIGNAL CATEGORIES per fn-44 R24, only [user] / [paraphrase] tags) to their destinations; sections without conversation signal stay absent. Compute BIZ_SIGNAL_CATEGORIES (0..9) for Phase 6's R25 dispatch.
3. Must-ask cases (R9) — interactive only; autofix exits 2 if any fire. Hard-error conditions: ambiguous title / untestable acceptance / scope-conflict. Optional ambiguities use lead-with-recommendation + confidence tier.
4. Read-back loop (mandatory, even in autofix) — Write the full draft ONCE to a literal unique path (workflow.md §4.1 — the Write render is the read-back); the AskUserQuestion body carries the summary payload (R-ID list + [inferred] tally) and points to the render (interactive); autofix prints the summary payload to stdout (the render is the emission). Interactive: approve / edit / abort; edit cycles revise via Edit + full-file Read before re-approval. When 8+ acceptance criteria: include consider splitting? as an option (R11). When the glossary is populated (total_terms > 0) and the conversation surfaced new project vocabulary: surface term-add proposals + a consent question after approve (workflow.md §2.7 / §4.2; writes land in §5.8). When readiness is adopted (≥1 ready spec) and tracker.readyState is NOT configured: one Mark ready? consent question after approve, default keep-draft (workflow.md §4.2; write lands in §5.9). Autofix: requires --yes to commit; term proposals print as suggestions, never written; readiness never written.
5. Write via flowctl — flowctl spec create --title "..." --json → parse id → flowctl spec set-plan <id> --file <literal draft path> --json (consumes the §4.1 draft file — no heredoc re-authoring). Optional flowctl spec set-branch if user named one. Capture creates fresh specs; allocate R-IDs sequentially from R1. --rewrite resets readiness via idempotent spec unready (§5.3); consented mark-ready lands via spec ready (§5.9). When artifacts.html.enabled is true, Phase 5 closes by regenerating the spec render lens at .flow/artifacts/<id>/spec.html per the shared disclosure reference (plugins/flow-next/references/html-artifacts.md) and replacing the spec's artifact link line in place (workflow.md §5.10); the Phase 6 footer then names the artifact path. With the mode off/unset there is zero artifact-related behavior or output.
6. Suggested next step — print Spec captured at .flow/specs/<id>.md. plus /flow-next:plan <id> and /flow-next:interview <id> next-step hints. When BIZ_SIGNAL_CATEGORIES triggers flowctl scope suggest (R25 fire/no-fire threshold lives in flowctl — skill never re-implements the math inline), append the /flow-next:interview --scope=business suggestion line.

Output rules

The new spec is the deliverable — it lives in .flow/specs/<spec-id>.md after Phase 5. Standard output also receives:

• The full draft (Phase 4) — emitted once via the §4.1 Write render (interactive and autofix alike); the summary payload rides in the read-back question body (interactive) or prints to stdout (autofix).
• The created spec id + spec path (Phase 5).
• The next-step footer (Phase 6).

Autofix mode without --yes produces a draft + the "rerun with --yes" hint and exits 0 — no write happens, no spec is allocated.
