Source Intelligence

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.

Skills

Skill directory lookups happen on first use, shaving filesystem work off startup.

What

The lookup that resolves skill and plugin directory prefixes, including the staging subdirectory, now runs on first use rather than at module load, moving its filesystem work out of startup.

Evidence

syncOwnedPrefixes

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