# rlm_axiom_020

**principle**: Capability audit before every mission: check Model (context/output limits), MCPs (available tools), Beta features (1M context, computer use), and Capability Manifest. An agent that does not know what it can do will always underperform.

**evidence**: RULE 10. capability_audit.py runs on every SessionStart. capability_manifest.json is the source of truth. Model was incorrectly set to sonnet in session 80 (fixed to opus) — caught by audit.

**strength**: high
