Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

performance-goal scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

97% identical to performance-goal — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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;
    • after omx performance-goal complete succeeds, run /goal clear in 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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
