Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00637 |
| Opus 5.5 | $0.00016 | $0.00255 |
| Sonnet 5.5 | $0.00008 | $0.00127 |
| Haiku 4.5 | $0.00004 | $0.00064 |
Grade A, and why
milestone-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says
When this skill is invoked:
-
Read the milestone definition from
production/milestones/. -
Read all sprint reports for sprints within this milestone from
production/sprints/. -
Scan the codebase for TODO, FIXME, HACK markers that indicate incomplete work.
-
Check the risk register at
production/risk-register/. -
Generate the milestone review:

### 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]

- [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]

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

milestone-review is a skill published in the GitHub repository TraftG/opencode-game-studio (45 stars, last pushed 6mo ago), licensed MIT. It adds 40 tokens to every session and 637 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
gate-check
Validate readiness to advance between development phases. Produces a PASS/CONCERNS/FAIL verdict with specific blockers and required artifacts. Use when user says 'are we ready to move to X', 'can we advance to production', 'check if we can start the next phase', 'pass the gate'.
milestone-review
Generates a comprehensive milestone progress review including feature completeness, quality metrics, risk assessment, and go/no-go recommendation. Use at milestone checkpoints or when evaluating readiness for a milestone deadline.
init-template
First-time repo setup for new projects. Transforms the cloned OCGS template into a clean, ready-to-use game project with your own identity.
retrospective
Generates a sprint or milestone retrospective by analyzing completed work, velocity, blockers, and patterns. Produces actionable insights for the next iteration.
sprint-plan
Generates a new sprint plan or updates an existing one based on the current milestone, completed work, and available capacity. Pulls context from production documents and design backlogs.
create-epics
Translate approved GDDs + architecture into epics — one epic per architectural module. Defines scope, governing ADRs, engine risk, and untraced requirements. Does NOT break into stories — run /create-stories [epic-slug] after each epic is created.
