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.

Smaller adjustments

Small polish: credit labels, an extra help link, bigger artifact fetch limit, safer MCP environment handling.

env
What

A group of small changes to model rows, help links, artifact fetching and MCP environment expansion.

Details
  • the "Requires usage credits" suffix on model rows moved into a shared helper applied to Fable entries, instead of being appended inline
  • a third support-article URL joined the set of links auto-marked with a "learn more: " marker
  • the artifact WebFetch read raises its maxContentLength by an extra 64KB of headroom
  • MCP env expansion for settings-provided env blocks now builds on a frozen snapshot of process.env, using a variant that no longer stashes NO_COLOR and FORCE_COLOR as a side effect
Evidence

artifact_webfetch_read

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