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 | $0.00091 | $0.02202 |
| Opus 5 | $0.00046 | $0.01101 |
| Sonnet 5 | $0.00018 | $0.00440 |
| Haiku 4.5 | $0.00009 | $0.00220 |
Grade A, and why
game-brainstorming 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.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Game Brainstorming — design before code
Turn a vague idea into an approved GDD plus an approved implementation plan, through collaborative dialogue.
Implementation skills covered by the gate:
bootstrap-godot-projectcreate-scene,create-component,create-state-machine,create-resource,create-autoloadsetup-collision-layers,setup-input-map,setup-save-system,setup-localization,save-schema-migrationui-patterns-godot,networking-foundation,setup-git-godotgenre-pack-platformer,genre-pack-topdown,genre-pack-3d-action,genre-pack-turnbasedshader-writer,sfx-generator,export-config
Opt-out: the user may bypass the gate by saying /skip-design, skip design, no GDD, or any equivalent phrasing. When that happens, skip directly to implementation but warn ONCE: "Skipping design pass — flagging that scope creep, mismatched art, and throwaway code are the typical failure modes here. I'll proceed if you confirm." Wait for the confirmation, then proceed without further re-warning in this session.
Always-allowed without gate: read-only skills (godot-patterns, performance-audit), maintenance skills (update-docs, gut-test-writer), and analysis agents (code-reviewer, playtest-analyst, gdscript-migrator).
Checklist
Create a task per item. Complete in order:
- Explore project context — list files, read
README.md/docs/if present, rungit log --oneline -20if it's a git repo. Detect whether this is greenfield (noproject.godot) or extending an existing project. - Confirm scope class — jam (≤72h), prototype (1–4 weeks), vertical slice (1–3 months), full game. Different scopes warrant different depth of brainstorm.
- Ask clarifying questions one at a time — see "Question playbook" below. Cover all relevant dimensions.
- Propose 2–3 design directions — with trade-offs. Recommend one. Ask user to pick.
- Present GDD outline section by section — get user approval after each section before moving on.
- Write the GDD — invoke
gdd-writerskill to save underdocs/design/<YYYY-MM-DD>-<slug>-gdd.md. - Spec self-review — re-read the saved GDD. Check for placeholders (
TBD,???), contradictions, ambiguity, scope creep beyond the agreed scope class. Fix inline. - User reviews the GDD file — ask user to read the saved file and confirm or request changes.
- Hand off to
writing-game-plan— that skill produces the implementation plan and applies its own user-approval gate. Brainstorming ends here.
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.

game-brainstorming is a skill published in the GitHub repository Simone-Tarantino/godot-superpowers (2 stars, last pushed 4mo ago), licensed MIT. It adds 91 tokens to every session and 2,202 once invoked, about $0.0005 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.

game-build-team
Build a Godot 4 / GDScript game feature with a coordinated agent team — a Manager (you), a Creative Director, a Logic Developer, an Animation Developer, and a Tester — that iteratively and autonomously design, build, juice, and verify the feature against the project's design contract to a strict, un-skippable quality…
avatar-contribution-pr
Turn an avatar GitHub issue (from the in-app avatar-editor easter egg) into a merged sprite — validate the art, then either add a new module or replace an existing one, and open a PR that closes the issue. Handles both "Avatar contribution: " (a brand-new sprite) and "Avatar edit: " (a hand-redraw of an existing…

Use ONCE per browser-game project to set up the game-qa infrastructure. Copies the shipped runner template, the adapter skeleton, and the journey schema; gap-fills the project's existing debug system if one is present. Skip for non-game projects.
requesting-game-qa
Use ONLY for QA on browser-game feature work. Triggers when the engineer signals readiness for QA: "request QA on X", "verify X", "QA this", "ready for QA on X", "this should be ready, can we make sure it works?" Compiles a brief, drives test-plan sign-off, then hands off to game-qa. Skip for tooling, build scripts…
