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.
The Read tool documentation now unconditionally requires absolute file paths. The previous conditional behavior (which sometimes allowed relative paths) has been removed for consistency.
Evidence
Read tool description change — removed conditional qk6() check, hard-codes "must be an absolute path" (search for "must be an absolute path")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
