Pros
  • Open standard with broad adoption across major coding agents (Claude, Cursor, Copilot, Codex, Gemini CLI, etc.)
  • Progressive disclosure keeps agent context lean while supporting many skills
  • Skills are just folders with a SKILL.md — trivial to author, version, and share via git
  • Write once, run across any skills-compatible client — no per-tool rewrites
  • Backed by Anthropic but governed as an open ecosystem on GitHub
  • Git-style version history and activity log for every prompt change
  • Remix sandbox isolates experiments from production prompts
  • REST API lets you swap prompts without redeploying the app
  • Built for multi-user team editing, not just solo developers
Cons
  • Not a product — you still need a compatible agent to actually run skills
  • Standard is young; conventions and tooling are still evolving
  • No built-in marketplace or discovery beyond what each client provides
  • No free tier; cheapest plan is $20/mo
  • Stingy token allowance (5K/seat) for in-app testing
  • Lighter on observability/analytics than Langfuse or Helicone
  • Supported model providers not clearly listed on the site
