The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill describes building applications that process external data via web frameworks and databases, which introduces an indirect injection surface.
Ingestion points: FastAPI request bodies, Pydantic models, and SQLAlchemy database records in references/detailed-guide.md.
Boundary markers: SKILL.md includes explicit instructions to 'Validate untrusted input at the edge' and 'Use parameterized queries'.
Capability inventory: Execution of local development tools (pytest, ruff, mypy), database migrations (alembic), and network operations (httpx) described across both files.
Sanitization: Instructions mandate using framework-supported encoding and avoiding the deserialization of untrusted code.
[COMMAND_EXECUTION]: The guide provides numerous examples of standard Python development and project management commands.
References usage of uv, poetry, pytest, ruff, mypy, nox, just, and task for routine tasks like linting, testing, and environment management.
Includes examples of CLI tool installation using uv tool install, which is a standard package management operation.
[EXTERNAL_DOWNLOADS]: The guide references several well-known and official repositories for development tools.
Links to official documentation and repositories for Ruff, mypy, and pre-commit hooks hosted on GitHub.
Provides examples of fetching data from generic external APIs (api.example.com) using httpx in code snippets.
