cancel

cancel is a skill for Codex from Tenon-Net/TenonAdmin. It costs 21 tokens per session (595 once invoked), scanned A, original, Apache-2.0.

Use /cancel (or cancelomc / stopomc) to stop an active OMX mode and perform its documented cleanup. Read AGENTS.md#durable-runtime-invariants-canonical-ssot first; it is the invariant authority for scope, ownership, hooks, and Team cleanup.

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

cancel 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.

Cancel Skill

When to use

Use /cancel (or cancelomc / stopomc) to stop an active OMX mode and perform its documented cleanup. Read AGENTS.md#durable-runtime-invariants-canonical-ssot first; it is the invariant authority for scope, ownership, hooks, and Team cleanup.

Inputs and preconditions

  • Accepted forms are /cancel and /cancel --force.
  • Reject --all, unknown flags, repeated flags, and mixed flags before mutation.
  • Discover the current session/root with the state read surfaces before cleanup:
    omx state list-active --json
    omx state get-status --mode <mode> --json
    
  • Confirm the current session/root and exact target before cleanup; stop when the required evidence is missing.

Operational steps

  1. Parse and validate arguments; select one exact session/root scope.
  2. Inspect active modes in dependency order: autopilot → ralph → ultrawork → ecomode → ultraqa → swarm → ultrapilot → pipeline → team → plan-consensus. Legacy names here are recovery inputs, not entrypoints for new work. Use the installed runtime's status/API for current modes; this historical list is not an exhaustive discovery filter.
  3. Cancel Autopilot while preserving its resumable state; clean only linked child modes it owns.
  4. For legacy Ralph, terminalize the target state (active:false, current_phase:"cancelled", completed_at) and a proven linked Ultrawork/Ecomode state in the same scope. Confirm post-conditions against the installed OMX release's docs/contracts/ralph-cancel-contract.md; this is an upstream runtime reference, not a TenonAdmin file. If unavailable, report the missing recovery contract rather than inventing cleanup steps.
  5. Clear standalone modes only after proving they are not linked to another active mode.
  6. For Team, inspect the runtime with omx team status <team> --json; use omx team shutdown <team> after the normal completion gate, or follow the explicit abort path.
  7. Clear only the selected mode/session state through the state API, for example:
    omx state clear --input '{"mode":"<mode>","session_id":"<session>"}' --json
    
  8. With --force, perform its documented native-stop cleanup. Report rollback or cleanup failures rather than claiming success.

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.
