ChangesSection of the release
What
A new hook event type that fires whenever an instruction file (CLAUDE.md or a rule file) is loaded during a session.
Details
- Hook receives context about which instruction file was loaded
- Can be used for auditing, logging, or dynamically responding to instruction changes
- Follows the same async/sync hook response patterns as other hook events
Evidence
Hook registration (search for "InstructionsLoaded", "When an instruction file (CLAUDE.md or rule) is loaded")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
