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 | $0.00002 | $0.00411 |
| Opus 5 | $0.00001 | $0.00205 |
| Sonnet 5 | $0.00000 | $0.00082 |
| Haiku 4.5 | $0.00000 | $0.00041 |
Grade A, and why
general 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 3d 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.

Code Style Guidelines
- TypeScript with strict type checking
- Single quotes for strings
- Trailing commas required
- Max line length: 80 chars
- No semicolons
- Use async/await for promises
Import Order (via @trivago/prettier-plugin-sort-imports)
- Node built-ins (^node:)
- External packages (^@?\w)
- Internal aliases (^@/)
- Relative imports (^[./])
Error Handling
- Use zod for runtime type validation
- Prefer throwing errors over returning null/undefined
- Use descriptive error messages
Naming Conventions
- PascalCase for types/interfaces/classes
- camelCase for variables/functions
- Use type over interface where possible
- Suffix tool classes with 'Tool'
- MCP tools are prefixed with 'umi-' (e.g., umi-help, umi-config-list)
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.

general is a cursor rule published in the GitHub repository umijs/umi-mcp (21 stars, last pushed 1y ago), licensed MIT. It adds 2 tokens to every session and 411 once invoked, about $0.0000 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 2026-08-30.
