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.

Improved Explore Agent Description

The Explore (search) agent description has been rewritten to be more precise about its limitations: it is now described as a "read-only search agent" that should NOT be used for "code review, design-doc auditing, cross-file consistency checks, or open-ended analysis" since it "reads excerpts rather than whole files and will miss content past its read window."

Evidence

New description string — search for "read-only search agent"

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