Phase 0: Parse Arguments

Extract the milestone name (current or a specific name) and resolve the review mode (once, store for all gate spawns this run):

1. If --review [full|lean|solo] was passed → use that
2. Else read production/review-mode.txt → use that value
3. Else → default to lean

See the installed Codex role-gate protocol for the full check pattern.

---

Phase 1: Load Milestone Data

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

Read all sprint reports for sprints within this milestone from production/sprints/.

---

Phase 2: Scan Codebase Health

• Scan for TODO, FIXME, HACK markers that indicate incomplete work
• Check the risk register at production/risk-register/

---

Phase 3: Generate the Milestone Review

# Milestone Review: [Milestone Name]

## Overview
- **Target Date**: [Date]
- **Current Date**: [Today]
- **Days Remaining**: [N]
- **Sprints Completed**: [X/Y]

## Feature Completeness

### Fully Complete
| Feature | Acceptance Criteria | Test Status |
|---------|-------------------|-------------|

### 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]
- **FIXME count**: [N]
- **HACK count**: [N]
- **Technical debt items**: [List critical ones]

## Risk Assessment
| Risk | Status | Impact if Realized | Mitigation Status |
|------|--------|-------------------|------------------|

## Velocity Analysis
- **Planned vs Completed** (across all sprints): [X/Y tasks = Z%]
- **Trend**: [Improving / Stable / Declining]
- **Adjusted estimate for remaining work**: [Days needed at current velocity]

## Scope Recommendations
### Protect (Must ship with milestone)
- [Feature and why]

### At Risk (May need to cut or simplify)
- [Feature and risk]

### Cut Candidates (Can defer without compromising milestone)
- [Feature and impact of cutting]

## Go/No-Go Assessment

**Recommendation**: [GO / CONDITIONAL GO / NO-GO]

**Conditions** (if conditional):
- [Condition 1 that must be met]
- [Condition 2 that must be met]

**Rationale**: [Explanation of the recommendation]

## Action Items
| # | Action | Owner | Deadline |
|---|--------|-------|----------|

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 with a Codex subagent using gate PR-MILESTONE (the installed Codex role-gate protocol).

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 the available user-input mechanism 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 the available user-input mechanism:

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

Codex portability

Use the search, file-editing, shell, user-input, and subagent capabilities available in the active Codex surface. Use PowerShell syntax on Windows and POSIX syntax on macOS/Linux; do not require a Unix compatibility layer on Windows. Inherit the active model and permission mode, and do not weaken approval or sandbox boundaries.
