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.

Claude Code v2.1.246

The claude-api skill's documents moved out of the bundle, unchanged

Under the hood
Useful1 Signal1
Skills

The claude-api skill's documents moved to separate files with identical content and paths.

What

This release removes a large block of text from the build, but nothing was dropped from the claude-api skill. It registers the same documents under the same paths and the same model-name placeholders; each document is now loaded from a separate file rather than sitting inline.

Details
  • Same paths, including csharp/claude-api/README.md, shared/model-migration.md, shared/prompt-audit.md and typescript/managed-agents/README.md.
  • Same placeholder table: FABLE_ID: "claude-fable-5", OPUS_ID: "claude-opus-5", PREV_OPUS_ID: "claude-opus-4-8".

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