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 v2.1.229

Session context is built lazily and cached per project root

Under the hood
Useful3 Signal2
Session Context

Git status, CLAUDE.md and other session context are now built on demand and cached per project.

What

Git status, Perforce notes, CLAUDE.md, user email, attached project and the current date are now assembled on demand and cached per project root, with explicit invalidation and a subscribe hook so callers hear about rebuilds. Timing is still reported through the existing context-completed log events.

Evidence

system_context_completed

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