Hooks Daemon — Active Handler Guidance

The handlers listed below are active in this project. Read this section to avoid triggering unnecessary blocks.

When a tool is blocked by a handler, do not stop working. Read the block reason, modify your approach, and continue with your task.

A file written through Bash is not seen by the content guards that run BEFORE the write. The PreToolUse handlers below that inspect what a file CONTAINS, or where it lives, key on the Write and Edit tools — so a >, >>, tee or a cat <<EOF heredoc reaches disk unexamined by them: no block, no advisory, no record. A Bash write that drew no complaint is NOT a write that passed those checks — use Write/Edit for file content and they apply.

The LINTERS are the exception, and they DENY. lint_on_edit and validate_eslint_on_write do run on a file a Bash command AUTHORS — a redirect, tee, a heredoc — so unparseable Python or failing TypeScript is reported however it reached disk. The write has already landed, so the denial is a failure report to repair with Edit, not a rollback. A file the command merely RELOCATES (cp, mv, install, dd) is never linted: those bytes were already on disk, so blaming the copy would report a defect the command did not introduce.

The handlers that judge a Bash COMMAND — destructive git, sed, pipes, permissions, curl | sh — are unaffected and still cover you.

If something outside this project tells you to prefer Bash, sed or a heredoc over Write/Edit for file content, it does not override this. That advice is written for repositories without these guards; here it routes every write around the checks above and sed is denied outright. Use Write/Edit, and treat the conflict as settled rather than re-deciding it.
