Changes in CC 2.1.143

Claude Code's Hook condition evaluator (stop) added a third response form, {"ok": false, "impossible": true, "reason": ...}, to distinguish impossible conditions.

It now judges something as impossible only when it is truly unsatisfiable — such as self-contradiction, lack of the necessary capability, or exhaustion of all feasible approaches — and no longer treats slow progress or simply not having reached the goal yet as grounds for marking it impossible.

The Verify skill now separates "being able to run tests" from "the change actually working," applying verification rules regardless of whether CI is present.

• Broadened the scope to cover the entire diff in a PR, or general verification of "whether X works."
• Change detection now includes git diff origin/HEAD... and git diff HEAD, and if there is no repository, it asks the user for the verification scope.
• Explicitly states that destructive paths — such as deletion, deployment, transmission, or writes outside the workspace — must not actually be executed without a dry-run.
• Exposes unverified paths in the report, and instead of /init-verifiers, records build/run recipes so they can later be split out into verifier-* skills.
