claude-api
Claude API and SDK documentation, packaged so Claude can reference method signatures directly while you build an LLM-powered app.
What it actually does
- A single, narrow official skill packaging Claude API and SDK documentation so Claude references it directly instead of guessing at method signatures.
When to use it — and when not to
Use it when
- You're building an app on the Claude API or SDK and want accurate method signatures rather than a model's memory of them.
Not for
- Your project doesn't touch the Claude API — it has no use outside that context.
Agent compatibility
- Claude Code
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
