What does this agent skill do?

!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys review_mode,automation,story_granularity,workflow

Resolved above — use as-is; --review overrides review_mode. No block → defaults in .claude/docs/config-resolution.md.

Existing Sprints

!ls production/sprints/ 2>/dev/null || echo "(no production/sprints/ directory yet)"

Resolved before this skill runs — use it to identify the previous sprint in Phase 1 rather than re-globbing.


Phase 0: Parse Arguments

Extract the mode argument (new, update, or status).

See .claude/docs/director-gates.md for the full check pattern. Individual gate definitions live in .claude/docs/director-gates/[gate-id].md — the spawned agent reads its own gate file; do not read it in the parent session.

Every AskUserQuestion call follows .claude/docs/automation-modes.md (collaborative asks always · guided major-only · autonomous logs and proceeds; automation_always_ask categories always prompt).

story_granularity — it sets how many stories to allocate per sprint, scaled by velocity: 2–4 at coarse (the default, via rigor: minimal), 6–10 at balanced (rigor: standard), 15–25 at fine. A Ready backlog smaller than the range is planned whole — never padded with invented stories.

Review mode check (before gates run):

  • Use the review mode from the resolved block above (--review overrides it for this run) — do not re-resolve it, and do not ask for it. With nothing configured it follows modes.rigor: solo at minimal, lean at standard.
  • Never write a review mode — not to project.yaml, not to production/review-mode.txt. modes.review_mode is one of the knobs modes.rigor fronts: pinning it in project.yaml shadows the rigor expansion, and the legacy file sits above that expansion, so either write would freeze director-review depth for good. --review covers a one-off. If the user wants a different depth to persist, point them to changing modes.rigor (/settings modes.rigor=<minimal|standard|full>), or to pinning it on purpose with /settings --local modes.review_mode=<full|lean|solo> (a personal override in project.local.yaml).

Phase 1: Gather Context

  1. Read the current milestone from production/milestones/ if it exists. No skill writes this directory — it is authored by hand from .claude/docs/templates/milestone-definition.md. On the majority of projects it is absent, which is the normal state, not a gap: note "no milestone defined — planning against the story backlog alone" and continue. Never block sprint planning on it, and never infer a milestone from the sprint files.

  2. Read the previous sprint (if any) from production/sprints/ to understand velocity and carryover. In new mode:

    • The new sprint's number [N] is the highest sprint-NNN.md in the Existing Sprints listing plus one (001 when there is none). It is the [N] in the plan's title, its QA plan path and the write ask.
    • Every story of the previous sprint that is not Complete — by its status in production/sprint-status.yaml, else its story file's Status line — goes in the Carryover table with a Reason and a New Estimate. It appears only there, never again as new Must Have / Should Have / Nice to Have work.
  3. Find the stories to plan — this is the actual backlog, and it is the one input this phase cannot do without:

    Glob production/epics/**/story-*.md
    Grep pattern="^> \*\*Status\*\*" glob="production/epics/**/story-*.md" output_mode="content"
    

    Stories live at production/epics/[epic-slug]/story-NNN-[slug].md — that is where /create-stories writes them and where /dev-story looks for them. Plan from the ones marked Ready. Use the grep rather than reading each story: at this stage you need status and title, not the body.

    If the glob returns nothing: "No stories found under production/epics/. Run /create-stories first (at standard/full, /create-epics before it)." Do not proceed to invent work items — a sprint plan that references stories which do not exist cannot be implemented. Verdict: BLOCKED — no stories to plan.

  4. Scan design documents in design/gdd/ for additional context on the features those stories implement. At workflow: minimal there are no per-system GDDs — use design/game-brief.md instead, and do not treat the absent GDDs as missing work. (Note: /sprint-plan is optional at minimal — the brief's Build order already is the plan.)

  5. Check the risk register at production/risk-register/ if it exists. Like the milestone above, no skill writes it — entries are authored by hand from .claude/docs/templates/risk-register-entry.md. If the directory is absent, say so once ("no risk register — risks assessed from the sprint contents only") rather than skipping risk assessment silently.


Phase 2: Generate Output

For new:

Generate a sprint plan following this format and present it to the user. Do NOT ask to write yet — the gate phases run first and may require revisions before the file is written: the producer feasibility gate (Phase 4, spawned only in full review mode — skipped in lean/solo) and the QA plan check (Phase 5, all modes).

## Definition of Done for this Sprint
- [ ] All Must Have tasks completed
- [ ] All tasks pass acceptance criteria
- [ ] QA plan exists (`production/qa/qa-plan-[sprint-slug]-[date].md`, from `/qa-plan sprint`)
- [ ] All Logic/Integration stories have passing unit/integration tests
- [ ] Smoke check passed (`/smoke-check sprint`)
- [ ] QA sign-off report: APPROVED or APPROVED WITH CONDITIONS (`/team-qa sprint`)
- [ ] No S1 or S2 bugs in delivered features
- [ ] Design documents updated for any deviations
- [ ] Code reviewed and merged

For update:

Update an existing sprint plan:

  1. Read the most recent sprint plan from production/sprints/.
  2. Present the current story list with their current statuses from production/sprint-status.yaml.
  3. Ask the user what to change: stories to add, remove, reprioritize, or re-estimate. Use AskUserQuestion to gather changes.
  4. Apply the changes and re-present the full revised plan for review.
  5. Re-run the producer feasibility gate (Phase 4) on the revised plan.
  6. Write the updated markdown plan and yaml together (same approval as new mode).

Note: update mode does not reset story statuses. Stories already marked in-progress or done keep their status. Only backlog and ready-for-dev stories can be removed or reprioritized freely.

For status:

Generate a status report:

# Sprint [N] Status -- [Date]

## Progress: [X/Y tasks complete] ([Z%])

### Completed
| Task | Completed By | Notes |
|------|-------------|-------|

### In Progress
| Task | Owner | % Done | Blockers |

Phase 3: Prepare Sprint Status File

After generating a new sprint plan, also prepare the production/sprint-status.yaml content. This is the machine-readable source of truth for story status — read by /sprint-status, /story-done, and /help without markdown parsing.

Do not write the yaml yet — hold it in context. The producer feasibility gate (Phase 4, full review mode only) may revise the story list; the QA plan check (Phase 5) runs in every mode. Both files are written together after Phase 5 in a single write approval.

Format:

# Auto-generated by /sprint-plan. Updated by /story-done and /dev-story.
# DO NOT edit manually — use /story-done to update story status.
#
# Status value mapping (yaml ↔ story file Status field):
#   backlog        ↔  Not Started
#   ready-for-dev  ↔  Ready
#   in-progress    ↔  In Progress
#   review         ↔  In Review
#   done           ↔  Complete
#   blocked        ↔  Blocked

sprint: [N]
goal: "[sprint goal]"
start: "[YYYY-MM-DD]"
end: "[YYYY-MM-DD]"
generated: "[YYYY-MM-DD]"
updated: "[YYYY-MM-DD]"

stories:
  - id: "[epic-story, e.g. 1-1]"
    name: "[story name]"
    file: "[production/epics/[epic-slug]/story-NNN-[slug].md]"   # the real path, verbatim from the Glob above
    priority: must-have        # must-have | should-have | nice-to-have
    status: ready-for-dev      # backlog | ready-for-dev | in-progress | review | done | blocked
    owner: ""
    estimate_days: 0
    blocker: ""
    completed: ""

Initialize each story from the sprint plan's task tables:

  • Must Have tasks → priority: must-have, status: ready-for-dev
  • Should Have tasks → priority: should-have, status: backlog
  • Nice to Have tasks → priority: nice-to-have, status: backlog
  • Carryover rows → the story's previous priority, and the status it has now

For update: read the existing sprint-status.yaml, carry over statuses for stories that haven't changed, add new stories, remove dropped ones.


Phase 4: Producer Feasibility Gate

Review mode check — apply before spawning PR-SPRINT:

  • solo → skip. Note: "PR-SPRINT skipped — Solo mode." Proceed to Phase 5 (QA plan gate).
  • lean → skip (not a PHASE-GATE). Note: "PR-SPRINT skipped — Lean mode." Proceed to Phase 5 (QA plan gate).
  • full → spawn as normal.

Before finalising the sprint plan, spawn producer via Agent using gate PR-SPRINT (.claude/docs/director-gates/pr-sprint.md).

Pass: proposed story list (titles, estimates, dependencies), total team capacity in hours/days, any carryover from the previous sprint, milestone constraints and deadline.

Present the producer's assessment.

If UNREALISTIC: revise the story selection (defer stories to Should Have or Nice to Have) and re-present the updated plan, then continue to Phase 5.

If NOT ASSESSED: name the missing input — it is not REALISTIC. Supply it and re-run PR-SPRINT, or record NOT ASSESSED — [missing input] for PR-SPRINT in the plan's header (.claude/docs/director-gates.md) and continue to Phase 5, repeating it at the write ask.

If CONCERNS, use AskUserQuestion:

  • Prompt: "Producer flagged concerns with this sprint plan. How do you want to proceed?"
  • Options:
    • [A] Proceed as planned — I accept the risk
    • [B] Adjust scope — defer some Should Have stories
    • [C] Extend the sprint timeline

If [A]: continue to Phase 5. If [B]: revise the story list, re-present the updated plan, then continue to Phase 5. If [C]: adjust sprint dates and capacity, re-present the updated plan, then continue to Phase 5.

After handling the producer's verdict, continue to Phase 5. The write comes at its end, so the file you approve already holds everything Phase 5 adds.


Phase 5: QA Plan Gate

Before closing the sprint plan, check whether a QA plan exists for this sprint.

Use Glob for production/qa/qa-plan-*.md — /qa-plan writes qa-plan-[sprint-slug]-[date].md — and keep a file whose name or content references this sprint number.

If a QA plan is found: note it in the sprint plan output — "QA Plan: [path]" — and proceed.

If no QA plan exists: do not silently proceed. Surface this explicitly:

"This sprint has no QA plan. A sprint plan without a QA plan means test requirements are undefined — developers won't know what 'done' looks like from a QA perspective, and the sprint cannot pass the Production → Polish gate without one.

Run /qa-plan sprint now, before starting any implementation. It takes one session and produces the test case requirements each story needs."

Use AskUserQuestion:

  • Prompt: "No QA plan found for this sprint. How do you want to proceed?"
  • Options:
    • [A] Run /qa-plan sprint now — I'll do that before starting implementation (Recommended)
    • [B] Skip for now — I understand QA sign-off will be blocked at the Production → Polish gate

Wait for this answer before the write ask below — the two are separate questions.

If [A]: note in the plan "QA plan: run /qa-plan sprint before implementation begins." If [B]: add a warning block to the sprint plan document:

> ⚠️ **No QA Plan**: This sprint was started without a QA plan. Run `/qa-plan sprint`
> before the last story is implemented. The Production → Polish gate requires a QA
> sign-off report, which requires a QA plan.

Write the plan

Ask: "May I write the sprint plan to production/sprints/sprint-NNN.md ([N] zero-padded to three digits) and production/sprint-status.yaml?" If yes, write both files (creating directories as needed). Verdict: COMPLETE — sprint plan and status file created. If no: Verdict: BLOCKED — user declined write.

After writing, add:

Scope check: If this sprint includes stories added beyond the original epic scope, run /scope-check [epic] to detect scope creep before implementation begins.

If the user chose Run /qa-plan sprint now in Phase 5, close with "Sprint plan written. Run /qa-plan sprint next — then begin implementation."


Phase 6: Next Steps

After the sprint plan is written and QA plan status is resolved:

  • /qa-plan sprint — required before implementation begins — defines test cases per story so developers implement against QA specs, not a blank slate
  • /story-readiness [story-file] — validate a story is ready before starting it
  • /dev-story [story-file] — begin implementing the first story
  • /sprint-status — check progress mid-sprint
  • /scope-check [epic] — verify no scope creep before implementation begins

Review mode configuration: All director gates (producer feasibility, QA review, code review) respect the project review mode, resolved in the block at the top of this skill (--review flag → project.local.yaml → modes.review_mode in project.yaml → production/review-mode.txt → the modes.rigor expansion, which yields lean at standard rigor and solo at minimal). This skill never asks for it or writes it; Phase 0 says where to point a user who wants a different depth. The mode is one of:

  • lean — skip non-phase-gate director gates (the rigor: standard value)
  • full — run all director gates as spawned sub-agents
  • solo — skip all gate spawning unconditionally (single developer, no review)

modes.review_mode in project.yaml is the primary source; production/review-mode.txt is the legacy fallback. Both are read by /sprint-plan, /story-readiness, /story-done, and other gate-using skills at startup.

Add the canonical catalog link to the repository README so users can inspect current installs and available audits. The publishing guide covers the complete discovery path.
