@ShivamPatxl I'd start with a permission check before a shell command. If the check times out, I'd want the command blocked, not waved through.

[Airlabs Fund @airlabsfund]

A failed hook can now stop the action.

Claude Code 2.1.295 adds onFailure: "block" for command and HTTP hooks:
- Can't start
- Times out
- Exits unexpectedly

Blocking is an explicit option, not a guarantee for every hook.

Interrupting a check shouldn't let the prompt through.

Claude Code 2.1.296 reports a fix for interrupted prompt hooks that could pass unchecked prompts. A useful regression test: interrupt the check, then verify the prompt stays blocked.

A held message was being reported as delivered.

Deletion safeguards need edge-case tests.

Claude Code 2.1.287 fixes an always-ask check that could disappear when a dangerous rm command also redirected output to a ~ or wildcard path.

Test command combinations, not just isolated actions.

[Airlabs Fund @airlabsfund]

Two fixes worth adding to agent regression tests in Claude Code 2.1.286:
