A planning assistant for turning a broad software idea into clear requirements and an organised implementation plan.

In plain words
What is it for?
Use it to plan features, review an existing plan, or gather requirements for a complex project.
Why use it?
It helps expose missing details, edge cases, and scope problems before coding begins.

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

omc-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 4d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 293 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<Use_When>

  • User wants to plan before implementing -- "plan this", "plan the", "let's plan"
  • User wants structured requirements gathering for a vague idea
  • User wants an existing plan reviewed -- "review this plan", --review
  • User wants multi-perspective consensus on a plan -- --consensus, "ralplan"
  • Task is broad or vague and needs scoping before any code is written </Use_When>

<Do_Not_Use_When>

  • User wants autonomous end-to-end execution -- use autopilot instead
  • User wants to start coding immediately with a clear task -- use ralph or delegate to executor
  • User asks a simple question that can be answered directly -- just answer it
  • Task is a single focused fix with obvious scope -- use an execution skill instead of running it from this planning module </Do_Not_Use_When>

<Why_This_Exists> Jumping into code without understanding requirements leads to rework, scope creep, and missed edge cases. Plan provides structured requirements gathering, expert analysis, and quality-gated plans so that execution starts from a solid foundation. The consensus mode adds multi-perspective validation for high-stakes projects. </Why_This_Exists>

<Execution_Policy>

  • Auto-detect interview vs direct mode based on request specificity
  • Ask one question at a time during interviews -- never batch multiple questions
  • Gather codebase facts via explore agent before asking the user about them
  • Plans must meet quality standards: 80%+ claims cite file/line, 90%+ criteria are testable
  • Consensus mode runs fully automated by default; add --interactive to enable user prompts at draft review and final approval steps
  • Consensus mode uses RALPLAN-DR short mode by default; switch to deliberate mode with --deliberate or when the request explicitly signals high risk (auth/security, data migration, destructive/irreversible changes, production incident, compliance/PII, public API breakage)
  • Planning/execution boundary: planning modes inspect context and produce plans/specs/proposals only. They MUST mark artifacts as pending approval unless the user has explicitly opted into execution in the current turn or via the structured approval UI. Before explicit execution approval, planning modes MUST NOT run mutation-oriented shell commands, edit source files, commit, push, open PRs, invoke execution skills, or delegate implementation tasks.
  • Goal workflow boundary: when a plan compares Claude Code /goal, Ralph, Team, or artifact-only Ultragoal, identify exactly one primary loop authority and use the deterministic conflict policies refuse, adopt_existing, and artifact_only rather than non-deterministic warning handling. /goal facts must cite Claude Code/Anthropic sources only (Claude Code /goal docs: https://code.claude.com/docs/en/goal; Anthropic Claude Code changelog: https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md), and plans MUST NOT claim the /goal evaluator independently runs commands or reads files; require surfaced proof evidence before any completion claim.
  • Goal workflow doc target: for user-facing comparisons, keep examples aligned with docs/shared/mode-selection-guide.md#goal-oriented-workflow-selection and docs/REFERENCE.md#goal-workflow-ux-goal-ralph-team-ultragoal. </Execution_Policy>

Mode Selection

Mode Trigger Behavior
Interview Default for broad requests Interactive requirements gathering
Direct --direct, or detailed request Skip interview, generate plan directly
Consensus --consensus, "ralplan" Planner -> Architect -> Critic loop until agreement with RALPLAN-DR structured deliberation (short by default, --deliberate for high-risk); add --interactive for user prompts at draft and approval steps
Review --review, "review this plan" Critic evaluation of existing plan

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.
