# Claude

## Profile

Claude is [[entity-org-anthropic-d43]]'s LLM family. The video heavily references Claude's implementation of skills.

## Specific References in This Source

- The skills primitive — a folder containing `skill.md` — was first formalized in Claude (see [[concept-skill-anatomy]]).
- Claude has a specific technical constraint around description parsing: see [[claim-single-line-description]].
- The video references how Claude's **latent space** responds to specific wording in skill methodologies.

## Reference

https://claude.ai/docs — supports `.md`-based skills with YAML metadata for agent tool-calling, emphasizing under-triggering and precise descriptions.
