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 | $0.00045 | $0.00627 |
| Opus 5 | $0.00023 | $0.00313 |
| Sonnet 5 | $0.00009 | $0.00125 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
help 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Port provenance: adapted from the pinned upstream source at

Contextual workflow navigator
Inspect the project read-only, infer its current stage from evidence, and show a compact menu containing only useful next actions. Do not run those actions.
Navigation method
- Inspect project files, current branch state, engine markers, design and
architecture documents, sprint artifacts, recent test evidence, generated
assets, and
.ai-game-studio/project.jsonwhen present. - State the detected stage and confidence. If evidence conflicts, explain the conflict in one sentence and ask a focused question.
- Recommend one primary next skill and no more than three alternatives.
- For every recommendation, include a copy-ready prompt beginning with the
exact namespaced invocation
$ai-game-studio:<skill>. - Mark workflows that require a plan and explicit confirmation before mutation.
Common paths
- New concept:
$ai-game-studio:brainstorm->$ai-game-studio:prototype->$ai-game-studio:art-bible->$ai-game-studio:map-systems. - Existing project:
$ai-game-studio:adopt->$ai-game-studio:project-stage-detect-> relevant audit or planning skill. - Playable prototype:
$ai-game-studio:prompt-to-game, followed by$ai-game-studio:playtest-reportand$ai-game-studio:scope-check. - Production assets: use the relevant generation skill, then
$ai-game-studio:visual-qa; use$ai-game-studio:quality-enhanceonly for an approved, reversible improvement. - Editor tooling:
$ai-game-studio:toolchain-doctor->$ai-game-studio:setup-engine->$ai-game-studio:engine-automation. - Release:
$ai-game-studio:smoke-check->$ai-game-studio:regression-suite->$ai-game-studio:release-checklist.
Distinguish product controls from skills: /plugins browses or installs plugins;
the / picker lists enabled skills; $ai-game-studio:<skill> invokes a workflow.
Never invent deprecated custom slash aliases.
What ships with it
1 file 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.
- 4d ago First seen · 48 lines · 45 tokens per session scan A 61138eac7234
help is a skill published in the GitHub repository frabcd/codex-ai-game-studio (8 stars, last pushed 3d ago), licensed MIT. It adds 45 tokens to every session and 627 once invoked, about $0.0002 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.

watch
File sentinel that monitors the working directory for changes and marker comments, then auto-triggers appropriate skills. Poll-based via git diff against the last scan commit. Writes intake items for batch processing and routes marker actions through /do. Use for automatic reactions to file changes; do NOT use for…

5-pass structured code review — correctness, security, performance, readability, consistency.
marshal
Meta-orchestrator that takes any direction — broad, specific, or vague — and autonomously chains skills and context into actionable work. Gathers context from codebase, docs, and memory. Only asks the user when it genuinely cannot proceed. Single-session orchestrator.
