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.

Detection of "I'll check back later" phrasing in model output

Under the hood
Useful2 Signal4
Model Output

Claude Code can now detect when the model says it will check back later.

What

Two case-insensitive patterns now look for deferral language: one for "I will / I'll / Will" followed by check back, re-check, poll, look again, retry, re-run or try again, and one for "Stopping here", "I've stopped here", "Parked the/this branch" or "Paused here". Both were empty no-op functions before, so this build is the first where they can match anything.

Details
  • The patterns are ungated where they are defined; what consumes a match is elsewhere in the build.
Evidence

Stopping here|I've stopped here|Parked (?:the|this) branch|Paused here

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