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 | $0.00033 | $0.01522 |
| Opus 5.5 | $0.00013 | $0.00609 |
| Sonnet 5.5 | $0.00007 | $0.00304 |
| Haiku 4.5 | $0.00003 | $0.00152 |
Grade A, and why
patch-notes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
83% identical to patch-notes — 102 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Port provenance: adapted from the pinned upstream source at
984023ddac0d5e27624f2baacde6105e45de375funder MIT; see the repository parity ledger for the exact path and blob.
Phase 1: Parse Arguments
version: the release version to generate notes for (e.g.,1.2.0)--style: output style —brief(bullet points),detailed(with context),full(with developer commentary). Default:detailed.
If no version is provided, ask the user before proceeding.
Phase 2: Gather Change Data
- Read the internal changelog at
production/releases/[version]$ai-game-studio:changelog.mdif it exists - Also check
docs/CHANGELOG.mdfor the relevant version entry - Run
git logbetween the previous release tag and current tag/HEAD as a fallback - Read sprint retrospectives in
production/sprints/for context - Read any balance change documents in
design/balance/ - Read bug fix records from QA if available
If no changelog data is available (neither production/releases/[version]$ai-game-studio:changelog.md
nor a docs/CHANGELOG.md entry for this version exists, and git log is empty or unavailable):
"No changelog data found for [version]. Run
$ai-game-studio:changelog [version]first to generate the internal changelog, then re-run$ai-game-studio:patch-notes [version]."
Verdict: BLOCKED — stop here without generating notes.
Phase 2b: Detect Tone Guide and Template
Tone guide detection — before drafting notes, check for writing style guidance:
- Check
.ai-game-studio/project.jsonfor any "tone", "voice", or "style" fields or sections. - Check
docs/PATCH-NOTES-STYLE.mdif it exists. - Check
design/community/tone-guide.mdif it exists. - If any source contains tone/voice/style instructions, extract them and apply them to the language and framing of the generated notes.
- If no tone guidance is found anywhere, default to: player-friendly, non-technical language; enthusiastic but not hyperbolic; focus on what the player experiences, not what the developer changed.
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.

patch-notes is a skill published in the GitHub repository frabcd/codex-ai-game-studio (17 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 1,522 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 83% identical to patch-notes, differing in 102 lines, and is treated as a copy.

scenario-maya-retopology-uv
Use when turning a dense sculpt, scan, ZBrush export or AI-generated mesh into animation-ready or game-ready topology in Maya without a mouse ("clean up this AI mesh", "retopo this character", Quad Draw, Retopologize), testing it deforms before rigging (bad elbow or wrist bend, lids popping through the eyes), or…
scenario-zbrush-expert
Use when an agent drives Maxon ZBrush 2026 for any task (sculpt in ZBrush, DynaMesh, ZRemesher, UVs, export, polypaint, posing, 3D print, clean up an AI mesh in ZBrush), when writing ZBrush Python (zbrush.commands) or ZScript, when the ZBrush bridge is not answering, a palette path or set() does nothing, a scripted…
scenario-godot-expert
Use when an agent drives Godot 4.7 on macOS or Windows for any task: headless --script jobs, --import, --check-only, command-line exports, GUT tests, windowed screenshots, the headless editor (-e) or an MCP server into a running editor; when a run hangs or fails silently, a capture is black, Godot 3 code breaks in…
scenario-godot-animation
Use when animating characters or scenes in Godot 4.7: AnimationPlayer clips and RESET, AnimationTree state machines and blend spaces built in code, Mixamo or glTF import, loop settings, BoneMap retargeting and shared animation libraries, root motion, foot sliding, foot IK with TwoBoneIK3D or custom SkeletonModifier3D…
motion
Reconstruct a skeleton from calibrated mesh projections and sequential VLM joint annotations, then fit joints and skin weights. Generate motion from joint-position trajectories, rhythm and contact constraints through IK; refine bone orientation against the action, then export, retarget and validate on the target mesh.
3d_scene
Choose how to build a 3dscene asset. Do not default to one pipeline for every task: what the user specified about the scene's appearance matters more than the scene type, and generative reconstruction is the least stable route here.
