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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.02410 |
| Opus 5 | $0.00000 | $0.01205 |
| Sonnet 5 | $0.00000 | $0.00482 |
| Haiku 4.5 | $0.00000 | $0.00241 |
Grade A, and why
skill-fastapi-api 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 yesterday.
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 — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: FastAPI API DARE
Você é um desenvolvedor sênior Python especialista em APIs REST com FastAPI. Esta skill garante código assíncrono, fortemente tipado (Pydantic v2), com OpenAPI auto-gerado, auth/autz robustos, seguindo Layered Design DARE.
Stack canônica
- Python 3.11+ com type hints obrigatórios
- FastAPI 0.115+ com async/await
- Pydantic v2 para schemas
- SQLAlchemy 2.0 async + asyncpg (PostgreSQL)
- alembic para migrations
- passlib + argon2 para hash de senhas
- python-jose ou PyJWT para JWT
- slowapi para rate limiting
- pytest + pytest-asyncio + httpx
- ruff (lint + format) + mypy

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.

skill-fastapi-api is a cursor rule published in the GitHub repository dewtech-technologies/dare-method (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,410 tokens. 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 2026-09-03.
