Install the milestone-review skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/Donchitos/Claude-Code-Game-Studios.git /tmp/Claude-Code-Game-Studios
mkdir -p ~/.claude/skills
cp -r /tmp/Claude-Code-Game-Studios/.claude/skills/milestone-review ~/.claude/skills/milestone-review

Insufficient input — check this before producing any report

If the inputs this skill needs do not exist, the answer is "could not run" — not a filled-in report. Check first, and stop if the check fails.

test results, registries, source code).

NOT ASSESSED — NO DATA. Do not estimate it, do not infer it from an adjacent artifact, and do not leave a mandated cell to be filled by whoever reads the template next.

  2. If any input required for a section is ABSENT, that section is

NOT ASSESSED — NO DATA as the whole verdict, naming what was missing and which skill produces it.

  1. If every required input is ABSENT, stop and report

A verdict of NOT ASSESSED is a success. It is the correct, useful answer to "what does the data say?" when there is no data. The failure mode this prevents is specific and has been observed in practice: report templates whose verdict enum had no "could not run" state produced false clean passes — an asset audit returning COMPLIANT on a project with no assets and no standards, and a performance profile reporting ">99% headroom against a 16.67ms budget" with zero profiler data and no budget ever set.

Absence of evidence is never evidence of absence. A scan that finds no matches because there are no files to scan has not verified anything. Say which of the two happened — a reader cannot tell from a green result.

Phase 0: Parse Arguments

Extract the milestone name (current or a specific name).

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; automationalwaysask categories always prompt).

Phase 1: Load Milestone Data

Read the milestone definition from production/milestones/ if it exists. If the argument is current, use the most recently modified milestone file.

No skill writes production/milestones/ — definitions are authored by hand

from .claude/docs/templates/milestone-definition.md, so most projects have

none. When the directory is absent or empty, say so and review against the

sprint reports alone; do not fabricate a definition. Take care with current:

this skill writes its own output as [milestone-name]-review.md, so a

most-recently-modified match can be a previous review rather than a

definition. Skip files ending -review.md when selecting.

Gather the sprint reports for sprints within this milestone from production/sprints/. Establish the denominator (glob them, count N), then scan the sections a milestone review actually aggregates rather than reading each report whole:

Grep pattern="^## (Sprint Goal|Capacity|Tasks|Carryover|Risks|Progress|Burndown Assessment|Emerging Risks|Definition of Done)" glob="production/sprints/sprint-*.md" output_mode="content" -A 12

**These alternates are copied from /sprint-plan's emitted headings — keep

them in sync with it, not with what a milestone review wishes existed.** The

previous pattern asked for Summary|Goal|Velocity|Completed|Blockers|

Retrospective, none of which /sprint-plan writes (it emits ## Sprint

Goal, not ## Goal). Only Carryover matched — and that was the trap: a

non-zero match count meant the zero-match escape hatch below could never

fire, so every milestone review silently aggregated carryover tables and

nothing else while reporting full coverage.

Full-read a single sprint report when its scanned sections point outside themselves, or when it matched nothing — a zero-match report predates the template and must be read, never silently dropped from the milestone's history. Report any sprint that contributed nothing: a milestone summary that quietly omits a sprint understates the work and the slippage both.

Phase 2: Scan Codebase Health

  • Scan for TODO, FIXME, HACK markers that indicate incomplete work
  • Check the risk register at production/risk-register/ if it exists (hand-authored from .claude/docs/templates/risk-register-entry.md; no skill writes it, so absence is normal — note it rather than skipping risk assessment silently)

Phase 3: Generate the Milestone Review

# Milestone Review: [Milestone Name]

- **Days Remaining**: [N]
- **Sprints Completed**: [X/Y]

## Feature Completeness

### Partially Complete
| Feature | % Done | Remaining Work | Risk to Milestone |
|---------|--------|---------------|------------------|

### Not Started
| Feature | Priority | Can Cut? | Impact of Cutting |

## Quality Metrics
- **Open S1 Bugs**: [N] -- [List]
- **Open S2 Bugs**: [N]
- **Open S3 Bugs**: [N]
- **Test Coverage**: [X%]
- **Performance**: [Within budget? Details]

## Code Health
- **TODO count**: [N across codebase]

- **Adjusted estimate for remaining work**: [Day

Phase 3b: Producer Risk Assessment

Review mode check — apply before spawning PR-MILESTONE:

  • solo → skip. Note: "PR-MILESTONE skipped — Solo mode." Present the Go/No-Go section without a producer verdict.
  • lean → skip (not a PHASE-GATE). Note: "PR-MILESTONE skipped — Lean mode." Present the Go/No-Go section without a producer verdict.
  • full → spawn as normal.

Before generating the Go/No-Go recommendation, spawn producer via Agent using gate PR-MILESTONE (.claude/docs/director-gates/pr-milestone.md).

Pass: milestone name and target date, current completion percentage, blocked story count, velocity data from sprint reports (if available), list of cut candidates.

Present the producer's assessment inline within the Go/No-Go section. The producer's verdict (ON TRACK / AT RISK / OFF TRACK) informs the overall recommendation.

If OFF TRACK, use AskUserQuestion before generating the recommendation:

  • Prompt: "Producer verdict: OFF TRACK. The milestone is in jeopardy. This review will recommend NO-GO. How do you want to proceed?"
  • Options:
  • [A] Accept NO-GO — generate the full review with that recommendation
  • [B] Override to CONDITIONAL GO — I'll document the accepted risks myself
  • [C] Stop — I want to address blockers before generating the review

If AT RISK, use AskUserQuestion:

  • Prompt: "Producer verdict: AT RISK. Milestone may slip. How should the Go/No-Go section be framed?"
  • Options:
  • [A] CONDITIONAL GO — include producer's conditions in the review
  • [B] NO-GO — conditions cannot be met in time
  • [C] GO — I accept the risk and want to proceed

Do not issue a GO against an OFF TRACK verdict unless the user explicitly selects [B] above.

Phase 4: Save Review

Present the review to the user.

Ask: "May I write this to production/milestones/[milestone-name]-review.md?"

If yes, write the file, creating the directory if needed. Verdict: COMPLETE — milestone review saved.

If no, stop here. Verdict: BLOCKED — user declined write.

Phase 5: Next Steps

  • Run /gate-check for a formal phase gate verdict if this milestone marks a development phase boundary.
  • Run /sprint-plan to adjust the next sprint based on the scope recommendations above.
