Plastic Intent Ending

Intent Ending

The one procedure every terminal transition routes through. Auto mode, the curator path, and releasing all call this skill (or its backing script, scripts/end-intent) for the mechanical close instead of restating the same prose three times. abandoned is the SAME procedure as delivered, not a failure branch: only outcome.md content and the INDEX section differ.

The 8 steps (0-7)

| # | Step | Who does it | |---|---|---| | 0 | Precondition check | You, before touching outcome.md | | 1 | outcome.md + intent-file ## Outcome summary | scripts/end-intent | | 2 | INDEX.md terminal move (Active -> Completed/Abandoned) | scripts/end-intent | | 3 | savepoint Done bookend | scripts/end-intent | | 4 | store auto-commit | scripts/end-intent | | 5 | disarm (worktree + lock) | scripts/end-intent (intent 188) | | 6 | QMD reindex, async, LAST | You | | 7 | EM-to-CTO report | You |

Steps 1-5 are ONE callable script call, not several separate one-liners: this is exactly what the failure mode this intent fixes looked like (releasing hand authored the close in prose and dropped the savepoint bookend for two real deliveries; separately, one session delivered four intents back to back and never ran the old step-5 one-liner at all, intent 188). Never restate outcome/INDEX/savepoint/disarm prose inline again; call scripts/end-intent.

Step 0. Precondition (the gate is section-blind, not selective)

Bridge.check_gate (scripts/lib/bridge.rb) is LIVE code already wired into the write-time hook. Its outcome.md rule is a blind scan of the WHOLE checklist.md: content.scan(/^- \[ \]/) counts every unchecked box, in every section, with no awareness of which section a box lives in. ANY unchecked box anywhere blocks the outcome.md write; there is no exemption for orchestrator-owned or completion-tracking items.

1. Read checklist.md. Tick every item as it is actually performed, including

an item that describes the close itself: running this very procedure IS what that item describes, so tick it at the moment you begin the close, before authoring outcome.md. By the time outcome.md is written, checklist.md must read 100 percent checked; there is no other way past the gate.

1. Confirm every acceptance criterion in spec.md is verifiable (tests pass,

or the manual check described in its HOW line was actually run).

1. If checklist.md still has an unchecked box, stop here. Finish it first

(tick it if the described work is actually done, or do the remaining work); do not attempt outcome.md and fight the gate's deny.

Step 1-5. Run scripts/end-intent

First author outcome.md for real (never leave the scaffold placeholder in place): copy templates/outcome.md, set the frontmatter to disposition: delivered or disposition: abandoned, and fill ## Summary, ## Delivered, ## Verification, ## Follow-ups. On abandon, ## Summary states the abandonment reason and the trail (see Pivot below). Also author the rich INDEX entry note now (a short line in the store's existing Completed/Abandoned convention: mode/tier, what shipped or why it was abandoned, suite result, merge/spawn notes); content authoring stays with you, --index-note only appends what you write.

Then call the script once:

ruby ~/.plastic/scripts/end-intent \
  --store  --id  --disposition delivered|abandoned \
  --session "$CLAUDE_CODE_SESSION_ID" \
  --outcome-summary "" \
  --index-note ""

This does all of steps 1-5 in order: guards outcome.md (refuses a missing, still-placeholder, or wrong-disposition file with exit 2 and authors nothing), stamps the intent file's ## Outcome section, moves the INDEX.md line from ## Active to ## Completed or ## Abandoned (dated today, idempotent, accepting either a real em dash or a plain hyphen as the id/ title separator on read while always emitting the real em dash on write) with the --index-note text appended after the date so the entry stays rich, appends the savepoint Done bookend, commits the store repo, and disarms (releases the code worktree and clears delivery.lock, verified against the durable lock file on disk, never merely trusted). Omit --index-note for a thin id+date entry, add --no-commit when a separate commit step already covers the store (this never skips disarm), and --dry-run to preview steps 1-5 with no writes.

A pre-flight lock guard runs before anything is written: it resolves the calling session (--session, else CLAUDE_CODE_SESSION_ID, else the existing lock's own recorded owner, else a no-op) and checks it against any existing delivery.lock. A live foreign session refuses the whole run (exit 4, nothing written); a stale foreign lock is reclaimed automatically (audited to savepoint.md) and the run proceeds as the new owner. Before removing the worktree, step 5 also refuses on an unexpectedly dirty code worktree (exit 5, naming the worktree path) rather than force-discarding uncommitted changes; pass --discard-worktree-changes only when you mean to override that deliberately.

On the auto mode / curator path (no release), this single call performs the FULL disarm (plain worktree remove, since the branch survives for later reclaim). On a release-shipped path, skills/releasing/SKILL.md merges and removes the worktree FIRST (its own step 8, merge-then-remove) before ever calling this script, so by the time this call's step 5 runs, the worktree is already gone (a harmless no-op) and only the lock is left to clear, correctly, for the first time on that path (D7).

Exit codes: 0 success (the intent is closed AND its delivery lock is gone); 1 a usage or resolution failure, OR an INDEX id that resolves to neither ## Active nor the terminal section; 2 the outcome.md guard refusing (fix outcome.md and re-run, nothing was written); 3 steps 1-4 already committed but disarm could not verify the lock is gone afterward (run /plastic-doctor check the lock status); 4 a live foreign session holds the lock (back off); 5 the code worktree is dirty (commit/stash first, or pass --discard-worktree-changes deliberately).

Step 6. QMD reindex, LAST

Only after step 5 has released the worktrees and cleared the lock, so the index never references state about to disappear:

ruby ~/.plastic/scripts/qmd-sync reindex --store  --async

No-op when QMD is absent. Runs in the background so it never blocks the turn.

Step 7. EM-to-CTO report

Brief the human like an engineering manager to a CTO: impact and risk first, in plain language, the decision left to them (merge, release, or accept). See outcome.md for the details; do not restate it verbatim.

Abandoned is the same procedure

disposition: abandoned runs the identical steps 0-7. The only differences are outcome.md content (Summary states why this was abandoned, not what was delivered) and the INDEX target section (## Abandoned instead of ## Completed). Never branch the mechanical steps by disposition; the script already does that internally.

Mid-flight pivot

When the work that shipped differs from what spec.md or plan.md originally called for, do not retcon those documents. Record the decision once in ## Insights, then let outcome.md carry the truth of what actually happened, including the abandoned trail when part of the work was dropped mid-flight. outcome.md is truth of delivery; spec and plan stay the historical record of what was planned.

Routing

plastic-releasing, plastic-auto, the curator agent, store-curating, and store-indexing all delegate their mechanical close to this skill (or call scripts/end-intent directly for steps 1-5). None of them restate the outcome/INDEX/savepoint/disarm prose inline any more; if you find one that does, that surface has drifted and should route here instead.
