# instructions-audit.sh — Log which CLAUDE.md / rules / skills loaded.

# Fires on: InstructionsLoaded
# Matcher: all
# Non-blocking: always exits 0.
# Skipped when TOOLKIT_HOOK_PROFILE=minimal.

# Provides an audit trail so we can see whether a CLAUDE.md rule actually
# entered the agent's context (vs. silently dropped due to token budget,
# nested include limits, or path-glob misses).
