DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.212

Propose Skills Tool

Claude now has a propose_skills tool that surfaces recurring multi-step procedures from the session as skill proposals. A review card appears in the conversation; nothing is written until you approve.

Details
  • Claude uses this tool when you ask to turn a workflow into a skill, or when it notices the same procedure has recurred.
  • The card shows up to 3 proposals at once.
  • Render-only — selecting a proposal on the card triggers the actual skill-save flow.
Evidence

"Surface recurring multi-step procedures from this session as skill proposals. Render-only — calling this shows a review card in the conversation; it does not write any files or create the skill." (search for "propose_skills")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
