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 v2.1.140

Plan Rejection Feedback Improved

What

When a user rejects a plan in plan mode and stays in planning, Claude now receives explicit context about what happened instead of inferring it.

Details
  • New message: "The agent proposed a plan that was rejected by the user. The user chose to stay in plan mode rather than proceed with implementation."
  • The rejected plan content is included so Claude can revise rather than re-propose the same plan.
Evidence

S06 string (search for "The agent proposed a plan that was rejected by the user")

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