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 | $0.00076 | $0.00314 |
| Opus 5 | $0.00038 | $0.00157 |
| Sonnet 5 | $0.00015 | $0.00063 |
| Haiku 4.5 | $0.00008 | $0.00031 |
Grade A, and why
architecture-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 10d 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
Port provenance: adapted from the pinned upstream source at
984023ddac0d5e27624f2baacde6105e45de375funder MIT; see the repository parity ledger for the exact path and blob.
Architecture Review
This is a full-fidelity Codex port of a large upstream studio workflow. Its
detailed phases, templates, checks, and handoff prompts live in
references/full-workflow.md to keep skill
discovery lightweight.
Required procedure
- Read
references/full-workflow.mdcompletely before executing this skill. - Follow its phases in order and preserve all approval, review, testing, and evidence gates.
- Adapt shell syntax to the detected platform; use PowerShell on Windows and POSIX syntax on macOS/Linux.
- Inherit the active Codex model and permission mode. Never weaken sandbox, approval, provenance, or human creative-control boundaries.
- If a referenced project artifact is absent, report the gap and use the documented fallback instead of inventing completion evidence.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

architecture-review is a skill published in the GitHub repository frabcd/codex-ai-game-studio (9 stars, last pushed 2d ago), licensed MIT. It adds 76 tokens to every session and 314 once invoked, about $0.0004 per session on Opus 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 2026-08-31.

lua-client-server-contract-audit
Use when normalized Lua client/server RPC contract copies or generated protocol tables disagree on opcode, request-response fields, types, ordering, or source authority.
mmorpg-packet-protocol-review
Use when a C++ server and Unity client protocol manifest or wire compatibility review covers packet version negotiation, numeric opcode registry, byte layout order, direction, and request-response pairing.
code-standards
C# coding standards and code review. Use when the user mentions coding standards or conventions, writing code to spec, defining standards for a project, cohesion and coupling, design pattern selection, or naming conventions, or wants a code review on the design and standards dimension.
improve
Autonomous quality improvement loop. Scores a target against a rubric, selects the highest-leverage axis, attacks it, verifies, documents, and loops. No pre-planning between iterations — each loop re-scores from scratch.
triage
GitHub issue and PR investigator. Pulls open issues/PRs, classifies them, searches the codebase for root cause or reviews contributed code, proposes fixes with file:line references, and optionally implements fixes. Use for investigating GitHub issues and reviewing PRs; do NOT use for general code review unrelated to…
