When Claude Code says a Stop hook already continued this turn (`stop_hook_active`), the hook never blocks: after its own block it records the result (`met_after_block` or `miss`). It also allows the stop while Agent dispatches are still running (no result yet, or launched in the background with no completion notice naming that agent), because their outputs may still arrive. Because Claude Code can fire Stop before the turn's last message reaches the transcript file, the hook reads the payload's `last_assistant_message` as the turn's final text. It blocks at most once per skill run. If the model stops again with the contract still unmet, the stop is allowed and the run is recorded as a miss. diff --git a/hosts/claude/hooks/skill-contract-stop-hook.ts b/hosts/claude/hooks/skill-contract-stop-hook.ts index b1adb0020..f46da16a2 100755 --- a/hosts/claude/hooks/skill-contract-stop-hook.ts +++ b/hosts/claude/hooks/skill-contract-stop-hook.ts @@ -5,13 +5,15 @@ * skill_contracts is on (env GSTACK_SKILL_CONTRACTS, then config * skill_contracts; default off). * - * stdin -> switch on? -> stop_hook_active? allow -> transcript_path -> parse + * stdin -> switch on? -> transcript_path -> parse (+ last_assistant_message) * -> the most recently loaded skill that declares a contract (none: allow) * -> Agent dispatches still running? allow (outputs may still arrive) * -> final turn?
