# pk protect

`pk protect` is a PreToolUse hook on Edit and Write. It denies any write
under the plans directory, `preserve.dir` in `.pk.json`, because a
preserved plan is a record of what was approved, and a record that can
be edited is not one.

The check resolves symlinks and compares case-insensitively on
Windows, so the directory cannot be reached through an alias.

## Amending a plan

Plans are superseded, never edited. When the approach changes, write
and approve a new plan. The sequence in the plans directory is the
history of decisions, reversals included.

`pk protect` is a no-op in an unconfigured repository (no `.pk.json`).

## Flags

<!-- generated: flags -->
Every command also accepts `--plain`, `--project-dir <value>`, and `--quiet`; see `pk help help`.
<!-- /generated: flags -->
