Agent skills for FastAPI projects
72 open-license skills in our database are built for FastAPI, and 317 skills match a typical FastAPI project. Below: what coding agents get wrong on FastAPI, 3 picks to start with, and where each agent loads them.
Updated 2026-10-18. Tags used for this page: python, fastapi.
What coding agents get wrong in FastAPI
Agents block the event loop with sync database calls inside async routes. They mix Pydantic v1 and v2 syntax and skip dependency injection for sessions and auth. Error responses drift from the OpenAPI schema.
Skills that help
Skills for async route patterns, Pydantic v2 models and dependency injection, plus pytest with an async test client.
Cursor rules: the database holds 28 Cursor rule files (.mdc) tagged FastAPI (fastapi, fastapi-application-rules, fastapi-application-structure, fastapi-backend-conventions, fastapi-best-practices, fastapi-blocking-operations, and more). Cursor reads them from .cursor/rules/. Other agents load SKILL.md skills, so most picks here are skills.
3 picks to start with
1. fastapi-python
Expert in FastAPI Python development with best practices for APIs and async operations
npx skills add Mindrally/skills --skill fastapi-python
2. fastapi-code-review
Reviews FastAPI code for routing patterns, dependency injection, validation, and async handlers.
npx skills add existential-birds/beagle --skill fastapi-code-review
3. fastapi-templates
Create production-ready FastAPI projects with async patterns, dependency injection, and comprehensive error handling.
npx skills add wshobson/agents --skill fastapi-templates

These 3 fit FastAPI in general. The scan box opens with a sample FastAPI description you can edit. A scan reads your repo or description, shows the match count and 2 picks free, and the full curated list (up to 30 picks with install commands, reasons and overlap notes) costs $9 once.
Where each agent loads FastAPI skills
- Claude Code: project folder
.claude/skills/, install flag--agent claude-code - Cursor: project folder
.cursor/skills/ or .agents/skills/, install flag--agent cursor - Codex: project folder
.agents/skills/, install flag--agent codex - GitHub Copilot: project folder
.github/skills/ or .agents/skills/, install flag--agent github-copilot
npx skills add owner/repo --skill skill-name --agent claude-code
How we count
We match project tags against 86,803 skills from 5,854 public GitHub repos (refreshed 2026-10-18). A skill built for another framework or language is left out, and so is a skill below our relevance floor. The picks on this page come from the ranked list for these tags. We favor broad practice skills over single-task ones. Licenses are shown as each repo declares them. Read a skill before you install it.
Questions
What agent skills should I use for FastAPI?
Start with a broad practice skill built for FastAPI, then add skills for testing and review. In our database 72 skills are tagged for FastAPI and 317 skills match a typical FastAPI project. The picks on this page are a place to start. A scan of your repo ranks the full list for your tasks.
Do Python skills work on a FastAPI project?
Yes. FastAPI implies Python in our matching, so a scan returns FastAPI skills first and then Python practice skills.
Are there Cursor rules for FastAPI?
Yes. The database holds 28 Cursor rule files (.mdc) tagged FastAPI. Cursor loads them from .cursor/rules/. Claude Code, Codex and Copilot do not read .mdc rules, so pick SKILL.md skills for those agents.
Where do FastAPI skills go for Claude Code, Cursor, Codex and Copilot?
Claude Code reads .claude/skills/, Cursor reads .cursor/skills/ or .agents/skills/, Codex reads .agents/skills/, and GitHub Copilot reads .github/skills/ or .agents/skills/. The install command takes --agent with the agent name and copies the skill folder there.
