What the reviewer found
LifeOS installs these under ~/.claude/hooks: ContextReduction.hook.sh rewrites every git/gh Bash command to run through the rtk wrapper via updatedInput, PreToolGuard.hook.ts routes Bash/Write/Edit through seven guard modules not included in the packet, AgentInvocation.hook.ts logs Agent dispatches (200-char prompt preview) to ~/.claude/LIFEOS/MEMORY, and TabState.hook.ts sets kitty tab titles; the definition also posts Skill and Agent payloads to http hooks on localhost:31337. Everything reviewed is local; no external network or credential access.

What the static scan said
The 26-rule scan found nothing in this file; the review read it anyway.
How this review was made
Fable 5.1 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
