Covers the full action lifecycle from src/actions/index.ts structure through error handling and redirect patterns. Does not cover Astro DB integration in depth (astro-db handles the database layer) or Content Layer schemas (astro-content) — this skill focuses on the request/validation/response boundary.

Astro Actions Expert

Type-safe server functions with automatic validation, standardized errors, and progressive enhancement.

Agent Workflow (MANDATORY)

Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:

1. fuse-ai-pilot:explore-codebase - Check existing actions in src/actions/
2. fuse-ai-pilot:research-expert - Verify latest Actions docs via Context7/Exa
3. mcp__context7__query-docs - Get defineAction and ActionError examples

After implementation, run fuse-ai-pilot:sniper for validation.
