feat: wire determinism hooks + add token asymmetry principle#608
Conversation
Register 3 hooks in settings.json: - instruction-compliance.py (PostToolUse, Agent) — compliance measurement - posttool-auto-test.py (PostToolUse, Write|Edit) — auto-test after edits - pipeline-phase-gate.py (PreToolUse, Write|Edit) — phase gate enforcement Add deterministic pre-routing Step 0 to /do SKILL.md Phase 2: - Calls scripts/pre-route.py before Haiku routing agent - High-confidence matches skip LLM routing entirely - Low/medium confidence falls through to Haiku as before
Tokens are not fungible. One Opus token costs ~30x one Haiku token. Optimizations that save cheap Haiku calls while risking expensive Opus rework loops are net losses. Pre-routing's value is determinism, not token savings. Phase gates prevent Opus rework, not hook overhead.
