plan

plan is a skill for Codex from Tenon-Net/TenonAdmin. It costs 26 tokens per session (424 once invoked), scanned A, original, Apache-2.0.

Use $plan when the user asks for a plan or plan review. Clear implementation and focused fixes should execute directly. A request to skip planning leaves this skill and continues the requested work; it does not create an Ultragoal or another persistent workflow unless the user explicitly requests one.

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

plan 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.

What it actually says

Plan

Use $plan when the user asks for a plan or plan review. Clear implementation and focused fixes should execute directly. A request to skip planning leaves this skill and continues the requested work; it does not create an Ultragoal or another persistent workflow unless the user explicitly requests one.

Modes

Mode Trigger Result
Direct Detailed planning request or --direct Write the plan from repository evidence
Interview --interview or a material unresolved decision Resolve the decision, then write the plan
Review --review Return APPROVED, REVISE, or REJECT with actionable reasons

Workflow

  1. Inspect the relevant repository facts before asking about codebase details.
  2. In interview mode, ask one focused question at a time and stop when the answer no longer changes the plan. In an attached OMX tmux runtime, use omx question; outside tmux, use native structured input when available, otherwise ask one concise plain-text question.
  3. Write the smallest plan that covers the requested outcome, affected files or components, testable acceptance criteria, implementation order, material risks, and verification.
  4. Cite concrete file paths and lines for consequential repository claims. Check that referenced files exist and that each acceptance criterion has an observable check.
  5. Save the result under .omx/plans/ unless the user requests another location.

For review mode, read the selected plan, test its claims against the repository, and explain every blocking gap. Use a specialist review only when it adds useful independent evidence.

Stop conditions

  • Deliver the plan when remaining uncertainty does not change implementation or acceptance criteria.
  • Escalate only a business or product trade-off that cannot be resolved from repository evidence or existing authorization.
  • If the user says continue, continue the current planning branch without restarting discovery.
Changes

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.
