Best Claude Skills for Developers (2026)
Coding agents are where skills started. Vercel’s React Best Practices skill encodes the performance rules its own team applies, Supabase and Neon publish official Postgres skills for their platforms, and obra’s Systematic Debugging makes an agent find the root cause before it changes code.
Narrower skills cover one job well: Rails Upgrade walks a Rails version bump, Vexor adds semantic code search, and Composio’s Changelog Generator writes release notes from commits.
These are for Claude Code, Cursor and similar agents. BusinessMCP complements them with a hosted MCP endpoint that gives the same agents your analytics, CRM and revenue data.

Which Postgres skill should I pick?
Supabase Postgres Best Practices if you run on Supabase, Neon Postgres if you run on Neon. Both cover schema and query practice; each adds its own platform’s features and limits.
Do these skills work with agents other than Claude?
Mostly yes. A skill is instruction text, so any agent that loads SKILL.md files can use it; the skills CLI installs them for Claude Code, Cursor, Codex, Copilot and others.
