# Check ticket implementation

Judge how much of a ticket is already implemented and report it so the user sees at a glance what
is done, what isn't, and what still needs attention.

## Gather

Input is a ticket URL / bare id — run [fetch-ticket](../fetch-ticket/SKILL.md) on it (it resolves
the tracker and planning dir and persists the `.TICKET.md`) — or a path to an already-fetched
ticket file or its task dir. Ambiguous input: ask, don't guess.

Run the fetch in a **subagent** when the runtime supports one, per fetch-ticket's
[delegate.md](../fetch-ticket/delegate.md), so its tool traffic stays out of this session's
context. Without subagent support, invoke fetch-ticket inline.

The **ticket text is what gets annotated** — its `.REQUIREMENTS.md` (same dir and `<id>-<slug>`
base — a shared dir may hold siblings'; none: the ticket's latest across `-vN` versions) may be
read as context for intent, never annotated in its place. The ticket text stays the contract: when
the requirements record an Override that changes a block's meaning, the verdict follows the text
and the note names the Override and its source.
Inspect downloaded attachments and design frames when they bear on a requirement being judged.

**Evidence base**: the current working tree, uncommitted changes included — unless the invocation
names something else (a branch, PR, commit range); then judge against that, read without moving
the working tree.

## Blocks

Turn every requirement-bearing statement into a block: description, acceptance criteria, and
comment statements that add or change requirements (attribute those, e.g. "from comment by X").
A later statement that changes an earlier one supersedes it: one block, quoting the latest text,
with the superseded text and its source in the note. Drop metadata and related-ticket lists; a
comment set aside as chatty goes to the `## Not judged` appendix — the full text stays in the
`.TICKET.md`.

- One block = one independently verifiable requirement, quoted **verbatim** under a short generated
  title, preserving ticket order.
- **Split on mixed verdict**: if two halves of a candidate block could end with different statuses,
  they are two blocks. PARTIAL always means one requirement itself half-built, never a bundle of a
  done and a not-done thing.

## Judge

Statuses: ✅ DONE · 🟡 PARTIAL · 🟥 NOT DONE · ⚪ NOT VERIFIABLE (can't be judged from the code —
say why, e.g. a manual deploy step).

- **The ticket text is the contract.** Tests, i18n, docs, and other project conventions affect the
  verdict only when the ticket demands them; a gap there is at most a remark in the note, never a
  downgrade.
- Verify by **reading**: search and read the code paths relevant to each block. When reading alone
  can't settle a verdict, say so in the note instead of guessing. Anything beyond reading —
  executing code, driving the app or a browser — only with the user's ok.
- Built but contradicting the text (a different rule, value or behavior) is 🟥 NOT DONE, the note
  opening with what was built instead; 🟡 is reserved for a requirement that is incomplete, never
  for one that is wrong.
- Every block gets a 1–2 sentence note and 1–3 `file:line` evidence refs showing where it was
  checked; for 🟡/🟥 the note must state what's missing or remaining.

## Report

Write `<task-dir>/<id>-<slug>.TICKET-STATUS.md`, overwriting any previous run — it is a snapshot of
now, and the header says when and against what. (No task dir and nothing to fetch? Follow the
project's/user's planning-dir convention, defaulting to `.agents/plans/`; ask only if genuinely
ambiguous.)

Format for human eyes — verdicts up front, blocks fenced by `━` rules. Before writing the notes,
actually invoke [explain-in-simple-language](../explain-in-simple-language/SKILL.md) and follow it —
reciting its rules from memory does not count. Not installed: plain words, one idea per sentence,
and nothing named only by a stand-in the reader hasn't seen.

```markdown
# <ticket title> — implementation status

> **Ticket** [<id>](<url>) · **Checked** <YYYY-MM-DD> · **Against** <branch>@<short-sha> (+ uncommitted)

**4 ✅ · 2 🟡 · 1 🟥 · 1 ⚪**

Needs attention: <titles of the 🟡/🟥 blocks>

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

### ✅ DONE — <block title>

> <verbatim ticket text>

<note> — `path/to/file.ts:42`

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

End the file with a `## Not judged` appendix, opened by a one-liner saying it is tracing only: one
line per comment set aside, with the reason.

## Wrap up

Print the tally line, the needs-attention titles, and the project-relative path of the report.
Nothing more — what to do about the gaps is the user's call.

## Boundaries

- **Read-only** on tracker and code: never comment on or transition the ticket, never modify
  source. The only file written is the `.TICKET-STATUS.md` (plus whatever fetch-ticket persists
  when delegated).
- Never grill the user on requirement questions; uncertainty lands in the notes.
