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 callget_goalagain and pass that fresh snapshot toomx 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-latencyEmit the Codex goal handoff:
omx performance-goal start --slug startup-latencyRecord 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_goalonly 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"}), callget_goalagain, and pass that snapshot toomx performance-goal complete --codex-goal-json; - after
omx performance-goal completesucceeds, run/goal clearin the Codex UI before starting another goal in this same thread/session; OMX prints this terminal cleanup step but does not invoke hidden clear routes;
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.
Lifecycle: create_goal starts the Codex thread goal, update_goal({status: "complete"}) marks terminal success after the evaluator and audit pass, and /goal clear removes the completed thread goal when another same-thread goal is needed. OMX shell commands and hooks reconcile snapshots and print the cleanup instruction; they must not mutate hidden Codex goal state.
