Track Close

Instructions

Inputs

Invocation examples:

/track-close T49.1 "Canonical close skill authored and manifest registered."
/track-close T49.1 "Canonical close skill authored." next-steps="QA to run Bandit review."
/track-close T49.1 "Canonical close skill authored." backlog-title="Canonical close operation"

Step 1 — Write the exit record to tracks.md (D1 — set, not append)

Read docs/context/tracks.md.

Locate the block whose heading matches ## Track <track-id>: (case-insensitive on the ID portion).

If the block is absent: report "track not found; no action" and exit with code 0. Do not modify any file. Skip to Step 3.

If the block exists: set the following fields to exact values — do not append, do not add duplicate fields:

- **Status:** DONE

(The top-level - **Status:** line in the track block.)

Within the - **Exit Record** section of that block:

  - **Status:** DONE
  - **What happened:** <close-notes>
  - **Next steps:** <next-steps, or "None" if omitted>

Write the updated file back. The write is a set-not-append: locate the exact field line and replace its value. Never add a second instance of any field.

Idempotency:

• If all three exit-record fields already contain identical content to the incoming inputs, and the top-level Status: is already DONE → no write occurs. Report: "already closed — no change."
• If the block is already DONE but the incoming notes differ → overwrite the fields (explicit re-close). Report: "exit record updated."

Step 2 — Reconcile backlog.md (D2/D3 — exact/tagged match, removal)

Read docs/backlog.md. If the file is absent, skip silently.

Find a bullet line that satisfies either of these exact-match conditions (in priority order):

1. Tagged match: the line contains the literal text (T<track-id>) — e.g. (T49.1). Match is case-insensitive on the ID.
2. Title match: the line's leading bold text (the text between the first ** pair) is a case-insensitive exact match to backlog-title (only checked if backlog-title was supplied).

Match found: remove the matched line from the file. If the matched item is already absent → no-op (idempotent, already removed).

No confident match: do not modify backlog.md. Report: "no matching backlog item — backlog unchanged."

Constraint: never fuzzy-match. If neither exact condition is met, treat as no match. No substring guessing.

Step 3 — Report outcome

Output a short confirmation:

Track <track-id> closed.

tracks.md:   <"exit record set" | "already closed — no change" | "exit record updated" | "track not found; no action">
backlog.md:  <"item removed" | "no matching backlog item — backlog unchanged" | "item already absent — no change" | "skipped (file absent)">

Trigger Contract

This section is a language-agnostic specification. Callers that cannot invoke this skill directly (e.g. a GitHub Actions YAML/bash workflow) must replicate these exact semantics.

Inputs

What is written

docs/context/tracks.md — the following fields are set to exact values within the matching ## Track <track-id>: block:

- **Status:** DONE

(top-level Status field in the block)

- **Exit Record**
  - **Status:** DONE
  - **What happened:** <close-notes>
  - **Next steps:** <next-steps>

The write operation is set, not append. Running twice with identical inputs produces byte-identical file state.

docs/backlog.md (conditional) — the matched bullet line is removed. No other lines are modified.

What is NOT touched

• skills-manifest.json — no version bump.
• bun run build — not invoked.
• docs/archive/ — no archiving.
• git — no commit, no stage, no push.
• docs/context/plan.md — not modified.
• Any file not listed above.

Canonical exit-record shape

- **Exit Record**
  - **Status:** DONE
  - **What happened:** <close-notes verbatim>
  - **Next steps:** <next-steps, or "None">

Field order is fixed. No additional fields are inserted. No trailing whitespace after the value.

Exit codes

Idempotency

This skill uses set-not-append semantics throughout:

• Already closed, same content: tracks.md is not written; backlog.md lookup still runs (idempotent if item already removed).
• Already closed, different content: the exit record fields are overwritten. This is an explicit re-close, not a duplicate write.
• Backlog item already absent: no write to backlog.md; operation is a no-op.
• Track block absent (e.g. sprint archived): no write to tracks.md; graceful degrade — reports "track not found; no action" and exits 0.

Running /track-close N times with identical inputs produces the same file state as running it once.
