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 | $0.00397 | $0.00397 |
| Opus 5 | $0.00198 | $0.00198 |
| Sonnet 5 | $0.00079 | $0.00079 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
guidelines 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 2d 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
Tooling
- Use pnpm for package manager
- Use Tailwind CSS for styling
- Use Shadcn UI for components
- Use React for the frontend
- Use TypeScript for everything
- Use Vite or Next.js for the build
- Use ESLint for linting
- Use Prettier for formatting
- Use zustand for state management
- Use zod for validation
- Use react-hook-form for form handling
- Use tanstack-query for data fetching
Conventions
- Use camelCase for variables
- Use PascalCase for components
- Use kebab-case for files
- Use "const ComponentName = (props: Props) => {}" for components (not React.FC or function component)
- Do NOT use index.ts files for aggregating multiple exports
- Do NOT pass props when they can be accessed through a zustand store or a provider context
Refactoring
- When extracting components:
- Create a new file in the components folder if the component is reused across multiple files
- Write the component in the same file if the component is only used in one file
Tips
- When writing tool / util functions use JSDoc to add a description and maybe example if needed (without @param and @returns)
- Use tsc for typechecking.
Notes
- We are using a monorepo with pnpm and vite and next.js
- Shared package is used to share schemas and types between the packages
- We are using R2 for cloud storage
- We are using postgres with drizzle for the database
Instructions
- Always use the latest version of the libraries and tools - by installing them with pnpm
- Write clean, readable, logical, structured, extensible and maintainable codebase.
- NEVER think or design for backwards compatibility! Always rewrite and change all usages in code to the new system.
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.

guidelines is a cursor rule published in the GitHub repository vucinatim/air-jam (5 stars, last pushed 3d ago), licensed MIT. It adds 397 tokens to every session, about $0.0020 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.
Other cursor rules, from other repositories
server-security
Browser input is untrusted. All project filesystem access goes through ProjectService.resolveProjectPath → ProjectRootGuard.resolveSafe. Do not call path.resolve/readFile/writeFile on user-influenced paths without that guard.
typescript
TypeScript conventions for this monorepo (strict mode, Zod boundaries, package imports, naming). Apply when editing .ts/.tsx files.
architecture
Architectural and cross-package changes — dependency direction, editor/runtime boundaries, scene schema, persistence, renderer packages. Use when changing package boundaries, serialized formats, or multiple layers. Do not apply to localized UI, styling, or test-only edits.
godot-game-dev-studio
Godot 4.7+ game-development guidance.
vanjs-core
Whenever vanjs is mentioned.
angular-20
This rule provides comprehensive best practices and coding standards for Angular development, focusing on modern TypeScript, standalone components, signals, and performance optimizations.
