baton

Context budget guard and handoff relay: measures real context use per model request, stops subagents that run too long or too big, and hands work over to a fresh session before the main agent drowns.

baton reaches L2 (writes or runs) and passed claude plugin validate on Claude Code 2.1.312.

Events hooked: 9
API methods referenced: 16
Access from classified calls: L2, writes or runs: drives Claude, reads mod state, persists state, draws
Reads mod state: the scan does not record whose state, so this does not show that it reads another mod’s values
Static scan, not a runtime test

These are the hooks and API calls reported by claude plugin validate. Access levels describe the widest reach of those calls and are not safety ratings. Validation is a static check, not a runtime test, and a passing result does not prove that a mod works or is safe. What a mod can access and how the scan works.
