description: "[OMX] Run an evaluator-gated performance optimization workflow over Codex goal mode with durable OMX artifacts and safe goal handoffs."

Performance Goal Workflow

Use this skill when a user asks OMX to optimize performance and wants a goal-oriented loop rather than a one-off review.

Contract

• OMX owns durable workflow state under .omx/goals/performance/<slug>/.
• Codex goal mode owns only the active-thread focus/accounting primitive.
• Shell commands do not mutate hidden Codex goal state. They write artifacts and emit model-facing handoff text.
• No optimization work may start until an evaluator command and pass/fail contract exist.
• Do not call update_goal({status: "complete"}) until the evaluator has a passing checkpoint and a completion audit proves the objective is done; then call get_goal again and pass that fresh snapshot to omx performance-goal complete --codex-goal-json.

CLI

Create the workflow and evaluator contract:

omx performance-goal create \
  --objective "Reduce CLI startup latency by 20%" \
  --evaluator-command "npm run perf:startup" \
  --evaluator-contract "PASS when p95 latency improves by 20% and regression tests pass" \
  --slug startup-latency

Emit the Codex goal handoff:

omx performance-goal start --slug startup-latency

Record evaluator evidence:

omx performance-goal checkpoint --slug startup-latency --status pass --evidence "benchmark + tests passed"
omx performance-goal checkpoint --slug startup-latency --status fail --evidence "benchmark regressed"
omx performance-goal checkpoint --slug startup-latency --status blocked --evidence "missing fixture"

Complete only after a passing checkpoint:

omx performance-goal complete --slug startup-latency --evidence "final evaluator evidence" --codex-goal-json <get_goal-json-or-path>

Agent Loop

1. Run omx performance-goal create if no workflow exists.
2. Run omx performance-goal start and follow the handoff:
   • call get_goal;
   • call create_goal only when no active goal exists and the objective is explicit;
   • work only against the evaluator contract;
   • after evaluator pass and completion audit, call update_goal({status: "complete"}), call get_goal again, and pass that snapshot to omx performance-goal complete --codex-goal-json;
3. Optimize in small reversible patches.
4. Run the evaluator and related regression tests.
5. Record each pass/fail/blocker with checkpoint.
6. Complete only when the pass artifact exists and no required work remains.

Completion Gate

A performance goal is incomplete unless .omx/goals/performance/<slug>/state.json contains a lastValidation.status of pass and omx performance-goal complete receives a matching complete Codex get_goal snapshot via --codex-goal-json. Passing ordinary tests alone is not sufficient unless they are the declared evaluator contract.
