Ask with the question tool. Without one, list the options numbered and end your turn to wait. A skipped or dismissed question is not an answer: ask again in plain text.

Dev Story

Implements one story: checks it can start, marks it In Progress, hands the code to the right programmer agent with a brief built from the story, then checks the result parses and looks right, and hands off.

Writes (each after an ask that names it): the story's Status, Last Updated and ## Files, and its production/sprint-status.yaml entry. The programmer agents write the code and tests under the code root and test root (.claude/docs/code-root-resolution.md). The session checkpoint and the evidence stamp are written without an ask. Next: /story-done [story-path]; at standard and full, /code-review [files] first.

Asks follow .claude/docs/automation-modes.md (collaborative always asks, guided asks on major choices, autonomous logs and goes on; automation_always_ask categories always ask).

Checklist (copy it and tick as you go):

- [ ] Phase 1: story found, tier resolved
- [ ] Phase 2: prerequisites checked (ADR, manifest, dependencies)
- [ ] Phase 3: story marked In Progress (one ask)
- [ ] Phase 4: programmer and engine specialist chosen
- [ ] Phase 5: work handed out with a full brief
- [ ] Phase 6: finished? parse check, run and look, one Run result line
- [ ] Phase 7: summary, ## Files, checkpoint, closing block

Phase 1: The story

The text typed after the skill name is the story path. With nothing typed, take the story the checkpoint in production/session-state/active.md names and confirm it: "Continuing work on [title] — is that correct?" None there: ask "Which story are we implementing?" with the TODO rows of bash .claude/scripts/story-facts.sh --all as options. No story file under production/epics/ at all: stop with "No stories found in production/epics/ — run /create-stories [epic-slug] to make them (at standard and full, run /create-epics first if there is no epic yet)."

bash .claude/scripts/story-facts.sh <story-path> gives its type, layer, TR-IDs, ADRs and dependencies. Then read the story in full.

Tier. workflow for the story's system, keyed on the GDD filename stem of its GDD: path (design/gdd/<stem>.md → <stem>; the [system] of its TR-ID only when there is no GDD path): that system's system_overrides row if there is one, else the project value. Say it in your first reply: Tier: workflow [value]. That value, never rigor or qa.level, picks the Phase 2 column and the closing Next step.

Phase 2: Can it start?

Input	full	standard	minimal
TR registry docs/architecture/tr-registry.yaml	missing: stop, "Run /architecture-review to bootstrap it"	optional	not expected
The ADR the story names	missing, Proposed, Deprecated or Superseded: stop	the same, only when the story names one	the same, only when the story names one
Control manifest docs/architecture/control-manifest.md	missing: warn, go on	missing: warn, go on	not expected

A story whose ADR field reads N/A — [reason] names none.

The ADR. bash .claude/scripts/adr-status.sh <ADR id> gives its status and version. Stop messages: Proposed — "ADR-NNNN is still Proposed. Accept it with /architecture-decision accept ADR-NNNN before implementing." Deprecated or Superseded — "ADR-NNNN is [status]; point the story at [successor] (edit its ADR field; /create-stories never rewrites an existing story) before implementing." NOT_FOUND — "ADR file not found. Run /architecture-decision, or correct the story's ADR field."

Do not open the ADR. The story's ADR Decision Summary and Implementation Notes are what the programmer reads instead. Compare the ADR's version with the story's ADR Version:

• equal, or the story has no ADR Version (written before the stamp), or both are unversioned: trust the story. Note the last two in the summary ("summary trusted unverified").
• they differ, or the ADR is unversioned but the story names a date: read references/version-mismatch.md. On a match, do not load it.

Never treat an absent stamp as a stale one: unknown falls back to the story, and /story-readiness and /code-review are the checks that catch drift later.

The manifest. When it exists, compare its Manifest Version line with the story's. They differ: read references/version-mismatch.md.

Dependencies. For each path on the story's Depends on line, bash .claude/scripts/story-facts.sh <path>. Not COMPLETE: ask "[this story] depends on [dependency], which is [status], not Complete. How do you want to go on?" Options: Proceed anyway — I accept the risk / Stop — I'll finish the dependency first / It is done, the status was never updated — mark it Complete. Stop: the story is BLOCKED (Phase 7), no agent. Mark it: ask "May I set [path] Status to Complete?" first. Proceed: note it under Deviations. NOT_FOUND: warn "Dependency story not found: [path]".

Any stop above: no agent runs. Go to Phase 7 and write the BLOCKED checkpoint.

Phase 3: Mark it In Progress

Before any agent, ask once: "May I mark this story In Progress? This sets Status and Last Updated in [story path] and its entry in production/sprint-status.yaml, and at the end lists the files changed under its ## Files." Leave the sprint file out of the question when it does not exist. Put what you will do next before the question: the question is the last thing in the reply. On yes:

• bash .claude/scripts/md-section.sh set-field <story> Status "In Progress", then set-field <story> "Last Updated" <YYYY-MM-DD> --after Status. At minimal the story file is the only record of progress.
• production/sprint-status.yaml: this story's entry gets status: in-progress and the top-level updated today. No file: say Sprint status not updated: production/sprint-status.yaml absent.

Declined: change neither, print Story not marked In Progress — declined in the summary, and go on.

Phase 4: Who implements it

Config/Data stories need no agent. Show each value change as from → to, ask "May I write [data file]?", and edit it. Go to Phase 6.

Story	Programmer agent
Foundation layer, any type	engine-programmer
Type UI	ui-programmer
Type Visual/Feel	gameplay-programmer
Core or Feature, gameplay	gameplay-programmer
Core or Feature, AI or pathfinding	ai-programmer
Core or Feature, networking	network-programmer

The engine specialist, for every code story. From the specialists line above: code (specialists.code, the language specialist: it tells a Godot C# project from a GDScript one, which engine.name cannot), plus shader when the story touches shaders or materials and ui for a UI story; primary (the generic engine specialist) when code is unset. Name no specialist from memory: the line is the project's choice. Every value unset and no primary: say "No engine specialist configured" and go on without one.

Phase 5: Hand out the work

Hand the implementation to the programmer agent. The brief points at files; never paste whole documents into it.

• Objective: implement [story path] against its acceptance criteria, within its Out of Scope boundaries.
• Sources:
  1. The story file. It carries the criteria, the boundaries and the QA test cases.
  2. Each TR-ID (TR-[system]-NNN) to look up: in docs/architecture/tr-registry.yaml, the lines matching id: <TR-ID>\s*$. Its requirement text is the source of truth, not text quoted in the story.
  3. The ADR guidance, inline: the story's ADR Decision Summary and Implementation Notes. Never the ADR path.
  4. The control manifest's [Layer] Layer Rules, by section.
  5. naming.* in project.yaml and the perf_budgets line above.
  6. The test file path from the story's Test Evidence section.
• Tests, by qa.level, for Logic and Integration stories:
  • minimal: "Do not write a test file for this story — test evidence is waived at qa.level: minimal." Say it: an omitted line and a forgotten one look the same to the agent.
  • standard: "Write the test at [path] with the code. Each acceptance criterion needs at least one test function." Naming per engine from .claude/rules/test-standards.md. No random seeds, no time-dependent assertions, no external I/O.
  • full: the same, and "every criterion must be covered: /story-done blocks on any untested one."
• Output: the files created or changed, the test functions written, any question or blocker, and whether it finished.
• Boundaries: write code only under the resolved code root and tests only under the test root. Code root unresolved: write nothing and report it. Touch no file outside the story's scope: report the need instead. Doc comments on public APIs. An architectural choice the ADR does not cover: report the plan, don't decide it. No helper or abstraction for a one-time use, no error handling for cases that cannot happen (validate at input and data-file boundaries only), and general logic, never a value special-cased so a test passes.

Say what the brief leaves out, to both readers. Inputs Phase 2 found absent (the TR registry, an ADR, the manifest) are left out: tell the agent "No [input] is passed — it does not exist at this tier; do not go looking for it", and tell the user one line before handing out: Briefing omits: [inputs] — implementing against the acceptance criteria and the [GDD | brief].

Then hand the engine check to the specialist once the programmer reports. Brief: check the changed files for engine-API use that is wrong or changed in [engine + version], against docs/engine-reference/<engine>/; return a list of file, line, problem, fix; edit nothing. A problem that breaks a criterion goes back to the programmer once; the rest go in the summary.

Phase 6: Check the result

Did the agent finish? It stopped early, hit a limit, or its report ends mid-task: the story is INCOMPLETE. Say so as the headline, list what exists, name the breakage, offer to resume the agent. Never print "Implementation Complete" over it, and leave the status as it is.

Did it write what it said? First verify the artifact: a file the agent's report names that is not on disk is a failed step, however fluent the report: resume the agent and name the missing file. A report of BLOCKED, an error, or "cannot complete": say so at once, go no further past what it blocks, and give a partial report (.claude/docs/error-recovery-protocol.md). Scope too large: split it with /create-stories. The ADR and the story disagree: report the conflict; never guess.

Is the test there? At qa.level: standard and full, for a Logic or Integration story, look for the file at the Test Evidence path. Missing: at the type's BLOCKING level on the gate_level line, flag "story unverifiable — test required before /story-done"; at ADVISORY, note it as a recommendation. At minimal there is nothing to check: tests are waived.

Does it parse? Run the check whose exit code answers it, and report the command, the exit code and any error lines:

• Godot: godot --headless --path . --import once, then godot --headless --path . -s res://.claude/scripts/godot-parse-check.gd -- res://<each changed .gd>. Exit 1 means a script did not load; its PARSE FAIL: line names it. Never use --check-only, and --import alone is no parse check. The executable is the one commands.test names when its file name says godot (a wrapper such as bash run-tests.sh is not the editor), else engine.path, else godot. Never search the disk for one: when none of the three runs, the check is not verified.
• Unity, Unreal: read references/engine-checks.md.
• No engine executable: parse NOT VERIFIED — engine binary not available. Never infer from reading the code that it parses.

Run it and look (.claude/docs/run-and-observe.md). For every story a player can see (every Visual/Feel and UI story, and any other with a surface): launch straight into the scene the story touched, capture a screenshot straight into production/qa/evidence/[story-slug]/ ([story-slug] is the story file's name without .md; mkdir -p the folder first), stamp it with bash .claude/scripts/review-receipts.sh hash <each changed file> > production/qa/evidence/[story-slug]/stamp.txt, then open the image and compare it with the criteria. Not waived at qa.level: minimal. Report exactly one line, plain text starting Run result: (no bold: /story-done reads it as written):

• Run result: OBSERVED — <what was on screen> with the retained path;
• Run result: NOT VERIFIED — <reason> (no engine, nothing captured); at the default gate level this blocks a Visual/Feel or UI story at /story-done;
• Run result: N/A — <reason> for a story with nothing observable; the reason says why nothing is (/story-done does not accept "it's a Logic story").

Only the feel half of a Visual/Feel criterion (timing, weight) is DEFERRED to /team-qa: a still cannot show it.

This skill pre-approves godot on PATH. An engine run through engine.path or the executable commands.test names asks first: the user approves it once, or adds Bash(<that executable> *) to .claude/settings.local.json.

Phase 7: Summary, files, checkpoint

## Implementation Complete: [title]

**Files changed**:
- `[code root path]` — created / modified ([what])
- `[test path]` — [N] test functions
**Test evidence**: waived at `qa.level: minimal` — no test was required or written   (Logic/Integration at minimal, instead of the test line)
**Verification**: [command] — [exit code and result | parse NOT VERIFIED — <reason>]

**Acceptance criteria**:
- [x] [criterion] — [file:function | test name | OBSERVED in <image path>]
- [ ] [criterion] — DEFERRED: feel, needs a playtest
**Deviations**: [None | files outside scope, an accepted dependency or version risk]
**Engine risks**: [None | the specialist's findings]
**Blockers**: [None | each]

At qa.level: standard and full, add: "Run your test suite and confirm the new tests pass before /story-done: it checks that the test file exists, and runs nothing." At minimal leave that out: there are no tests to run. For a Visual/Feel or UI story with no retained image, add: "A retained screenshot under production/qa/evidence/[story-slug]/ is required before /story-done" (and, for Visual/Feel, the sign-off in production/qa/evidence/[story-slug]-evidence.md).

## Files. Replace the section's body with the list of changed code and test files, one per line, as the Phase 3 ask said: bash .claude/scripts/md-section.sh replace <story> "Files" with the list on stdin. A story with no such section: add ## Files and the list at its end, with a file edit, never a shell command (a shell write skips the project's write checks). Skip this when the Phase 3 ask was declined.

The checkpoint, on every outcome. Pipe the block to bash .claude/scripts/session-state.sh checkpoint, which replaces the old one:

**Updated:** [date]
**Branch:** `[current git branch]`
**Current task:** /dev-story — [story path] ([title])
**Next step:** [the Next step below]
**Blocked on:** [nothing, or the blocker]
**Files in progress:** [changed files, comma-separated]
**Run result:** [OBSERVED — … | NOT VERIFIED — … | N/A — …, as in the closing block: /story-done reads it here]
**Open questions:** [none, or one line each]

The run's last reply ends with this block, the only place the Run result: line is printed: print it nowhere else in the reply. The Next step goes by the tier you stated in Phase 1 (the workflow line, never rigor or qa.level). The Next step: at minimal, /story-done [path]. At standard and full, /code-review [files], then /story-done [path]. INCOMPLETE: /dev-story [path] to resume. BLOCKED: the action that unblocks it (/architecture-decision accept ADR-NNNN, the dependency to finish, the diff to review).

Story: [path] — [Implemented | INCOMPLETE — <breakage> | BLOCKED — <reason>]
Run result: [OBSERVED — … | NOT VERIFIED — … | N/A — …]
Next step: [Implemented, Tier: workflow minimal → /story-done [path] | Implemented, Tier: workflow standard or full → /code-review [changed files], then /story-done [path] | INCOMPLETE → /dev-story [path] to resume | BLOCKED → the unblocking action]
