# Story Done

This skill closes the loop between design and implementation. Run it at the end
of implementing any story. It ensures every acceptance criterion is verified
before the story is marked done, GDD and ADR deviations are explicitly
documented rather than silently introduced, code review is prompted rather than
forgotten, and the story file reflects actual completion status.

**Output:** Updated story file (Status: Complete) + surfaced next story.

---

## Phase 1: Find the Story

**If a file path is provided** (e.g., `/story-done production/epics/core/story-damage-calculator.md`):
read that file directly.

**If no argument is provided:**

1. Check `production/session-state/active.md` for the currently active story.
2. If not found there, read the most recent file in `production/sprints/` and
   look for stories marked IN PROGRESS.
3. If multiple in-progress stories are found, use `AskUserQuestion`:
   - "Which story are we completing?"
   - Options: list the in-progress story file names.
4. If no story can be found, ask the user to provide the path.

---

## Phase 2: Read the Story

Read the full story file. Extract and hold in context:

- **Story name and ID**
- **GDD Requirement ID(s)** referenced
- **ADR reference(s)** referenced
- **Acceptance Criteria** — the complete list (every checkbox item)
- **Implementation files** — files listed under "files to create/modify"
- **Engine notes** — any engine-specific constraints noted
- **Definition of Done** — if present, the story-level DoD
- **Estimated vs actual scope** — if an estimate was noted

Also read:
- The referenced GDD section — just the acceptance criteria and key rules, not
  the full document
- The referenced ADR(s) — just the Decision and Consequences sections

---

## Phase 3: Verify Acceptance Criteria

For each acceptance criterion in the story, attempt verification using one of
three methods:

### Automatic verification (run without asking)

- **File existence check**: `Glob` for files the story said would be created.
- **Test pass check**: if a test file path is mentioned, run it via `Bash`.
- **No hardcoded values check**: `Grep` for numeric literals in gameplay code
  paths that should be in config files.
- **No hardcoded strings check**: `Grep` for player-facing strings in `src/`
  that should be in localization files.
- **Dependency check**: if a criterion says "depends on X", check that X exists.

### Manual verification with confirmation (use `AskUserQuestion`)

- Criteria about subjective qualities ("feels responsive", "animations play correctly")
- Criteria about gameplay behaviour ("player takes damage when...", "enemy responds to...")
- Performance criteria ("completes within Xms") — ask if profiled or accept as assumed

Batch up to 4 manual verification questions into a single `AskUserQuestion` call:

```
question: "Does [criterion]?"
options: "Yes — passes", "No — fails", "Not tested yet"
```

### Unverifiable (flag without blocking)

- Criteria that require a full game build to test (end-to-end gameplay scenarios)
- Mark as: `DEFERRED — requires playtest session`

---

## Phase 4: Check for Deviations

Compare the implementation against the design documents.

Run these checks automatically:

1. **GDD rules check**: Read the GDD section referenced in the story. `Grep` the
   implemented files for key function names, data structures, or class names
   mentioned in the GDD. If the GDD specifies a formula, check for recognizable
   variable names from that formula.

2. **ADR constraints check**: Read the referenced ADR's Decision section. Check
   for forbidden patterns from `docs/architecture/control-manifest.md` (if it
   exists). `Grep` for patterns explicitly forbidden in the ADR.

3. **Hardcoded values check**: `Grep` the implemented files for numeric literals
   in gameplay logic that should be in data files.

4. **Scope check**: Did the implementation touch files outside the story's stated
   scope? (files not listed in "files to create/modify")

For each deviation found, categorize:

- **BLOCKING** — implementation contradicts the GDD or ADR (must fix before
  marking complete)
- **ADVISORY** — implementation drifts slightly from spec but is functionally
  equivalent (document, user decides)
- **OUT OF SCOPE** — additional files were touched beyond the story's stated
  boundary (flag for awareness — may be valid or scope creep)

---

## Phase 5: Code Review Prompt

After criteria verification and deviation check, use `AskUserQuestion`:

```
question: "Implementation verified. Run /code-review on the changed files?"
options:
  - "Yes — run /code-review now"
  - "Skip — I'll review manually"
  - "Skip — already reviewed"
```

If "Yes": list the files to review and say:
"Run `/code-review [file1] [file2]` to review the implementation before
marking complete."

Do not run code-review inline — surface it and let the developer decide when
to invoke it.

---

## Phase 6: Present the Completion Report

Before updating any files, present the full report:

```markdown
## Story Done: [Story Name]
**Story**: [file path]
**Date**: [today]

### Acceptance Criteria: [X/Y passing]
- [x] [Criterion 1] — auto-verified (test passes)
- [x] [Criterion 2] — confirmed
- [ ] [Criterion 3] — FAILS: [reason]
- [?] [Criterion 4] — DEFERRED: requires playtest

### Deviations
[NONE] OR:
- BLOCKING: [description] — [GDD/ADR reference]
- ADVISORY: [description] — user accepted / flagged for tech debt

### Scope
[All changes within stated scope] OR:
- Extra files touched: [list] — [note whether valid or scope creep]

### Verdict: COMPLETE / COMPLETE WITH NOTES / BLOCKED
```

**Verdict definitions:**
- **COMPLETE**: all criteria pass, no blocking deviations
- **COMPLETE WITH NOTES**: all criteria pass, advisory deviations documented
- **BLOCKED**: failing criteria or blocking deviations must be resolved first

If the verdict is **BLOCKED**: do not proceed to Phase 7. List what must be
fixed. Offer to help fix the blocking items.

---

## Phase 7: Update Story Status

Ask before writing: "May I update the story file to mark it Complete and log
the completion notes?"

If yes, edit the story file:

1. Update the status field: `Status: Complete`
2. Add a `## Completion Notes` section at the bottom:

```markdown
## Completion Notes
**Completed**: [date]
**Criteria**: [X/Y passing] ([any deferred items listed])
**Deviations**: [None] or [list of advisory deviations]
**Code Review**: [Pending / Complete / Skipped]
```

3. If advisory deviations exist, ask: "Should I log these as tech debt in
   `docs/tech-debt-register.md`?"

---

## Phase 8: Surface the Next Story

After completion, help the developer keep momentum:

1. Read the current sprint plan from `production/sprints/`.
2. Find stories that are:
   - Status: READY or NOT STARTED
   - Not blocked by other incomplete stories
   - In the Must Have or Should Have tier

Present:

```
### Next Up
The following stories are ready to pick up:
1. [Story name] — [1-line description] — Est: [X hrs]
2. [Story name] — [1-line description] — Est: [X hrs]

Run `/story-readiness [path]` to confirm a story is implementation-ready
before starting.
```

If no more stories are ready in this sprint:
"No more stories ready in this sprint. Consider running `/sprint-status` to
assess sprint health."

If all Must Have stories are complete:
"All Must Have stories are complete. Consider running `/milestone-review` or
pulling from the Should Have list."

## Collaborative Protocol

- **Never mark a story complete without user approval** — Phase 7 requires an
  explicit "yes" before any file is edited.
- **Never auto-fix failing criteria** — report them and ask what to do.
- **Deviations are facts, not judgments** — present them neutrally; the user
  decides if they are acceptable.
- **BLOCKED verdict is advisory** — the user can override and mark complete
  anyway; document the risk explicitly if they do.
- Use `AskUserQuestion` for the code review prompt and for batching manual
  criteria confirmations.
