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.

Skill template no longer emits an em dash

You'll notice

Skills

Generated skill scaffolds no longer include an em dash in the description placeholder.

SKILL.md
What

The SKILL.md scaffold's description placeholder now uses a comma, so generated skill frontmatter reads "one-line summary, used to decide relevance...".

Evidence

description: {{one-line summary, used to decide relevance in future conversations, so be specific}}

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