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.

MCP skill loading reports a surfaced count

Under the hood
Useful1 Signal0
MCP

Claude now counts how many skills an MCP server surfaced when loading them.

What

After loading skills from an MCP server, the loader calls a new reporting helper with "surfaced" and the skill count before writing the existing load log line.

Details
  • Runs on the same path that logs [mcp-skills] Loaded ....
  • No change to which skills load or how they behave.
Evidence

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