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.

Tab-indented YAML frontmatter now parses

You'll notice
Useful4 Signal1
Skills

Skill and agent files indented with tabs now load their metadata correctly.

SKILL.md
What

A SKILL.md or agent file indented with tabs used to load with empty metadata. Frontmatter parsing now retries after expanding each leading tab to two spaces, in both the runtime reader and the plugin, skill and agent validator.

Details
  • The retry returns a structured success or error result, so a genuine syntax error still logs "Failed to parse YAML frontmatter".
Evidence

let t = U1_(e).replace(/^\t+/gm, (r) => " ".repeat(r.length));

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