plan

plan is a command for coding agents from fmflurry/settings-opencode. It costs 6 tokens per session (281 once invoked), scanned A, a copy of plan, MIT.

A command that turns a requested change into a detailed implementation plan with requirements, phases, dependencies, risks, and an effort estimate.

In plain words
What is it for?
Use it to plan features, migrations, or other coding tasks that need a reviewed sequence of work and risk assessment.
Why use it?
It exposes unclear requirements and possible blockers before coding begins. It also requires explicit approval before implementation proceeds.

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 yesterday.

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

100% identical to plan — 11 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.

What it actually says

Plan Command

Create a detailed implementation plan for: $ARGUMENTS

Your Task

  1. Restate Requirements - Clarify what needs to be built
  2. Identify Risks - Surface potential issues, blockers, and dependencies
  3. Create Step Plan - Break down implementation into phases
  4. Wait for Confirmation - MUST receive user approval before proceeding

Output Format

Requirements Restatement

[Clear, concise restatement of what will be built]

Implementation Phases

[Phase 1: Description]

  • Step 1.1
  • Step 1.2 ...

[Phase 2: Description]

  • Step 2.1
  • Step 2.2 ...

Dependencies

[List external dependencies, APIs, services needed]

Risks

  • HIGH: [Critical risks that could block implementation]
  • MEDIUM: [Moderate risks to address]
  • LOW: [Minor concerns]

Estimated Complexity

[HIGH/MEDIUM/LOW with time estimates]

WAITING FOR CONFIRMATION: Proceed with this plan? (yes/no/modify)


CRITICAL: Do NOT write any code until the user explicitly confirms with "yes", "proceed", or similar affirmative response.

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.
