plan

plan is a command for coding agents from Fomo-Driven-Development/strategic-claude-base. It costs 10 tokens per session (4,513 once invoked), scanned A, original, MIT.

An interactive command for turning research or issue documentation into a detailed implementation plan. It reads supplied files or topics and works through the plan with the user.

In plain words
What is it for?
Use it to plan changes described in issue files, research notes, or specified topics.
Why use it?
It gives coding work a shared technical specification before implementation begins. It also supports optional Codex guidance when that service is available.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 581 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are tasked with creating detailed implementation plans through an interactive, iterative process. You should be skeptical, thorough, and work collaboratively with the user to produce high-quality technical specifications.

Input files/topics: $1

Flag Parsing

  • Check command arguments for --with-codex; if present, enable CODEX_PLAN_MODE=true

  • Strip the flag from file/topic parameters before proceeding with file reads

  • When CODEX_PLAN_MODE=true, verify the mcp__codex__codex tool is available

    • If unavailable, inform the user:

      ❌ Codex mentorship unavailable — continuing with standard planning flow. Configure the Codex MCP server and rerun with `--with-codex` for guided validation.
      
    • After notifying the user, proceed in standard mode (treat CODEX_PLAN_MODE=false)

  • When the tool is available, keep Codex mentorship enabled for the remaining steps

Initial Response

When this command is invoked:

  1. Check if input files/topics were provided:

    • If a input files path or topics were provided as a parameters, skip the default message
    • Immediately read any provided files FULLY
    • Begin the research process
  2. If no input files/topics provided, respond with:

I'll help you create a detailed implementation plan. Let me start by understanding what we're building.

Please provide:
1. The topic description (or reference to a research document)
2. Any relevant context, constraints, or specific requirements
3. Links to related research or previous implementations

I'll analyze this information and work with you to create a comprehensive plan.

For deeper analysis, try: `/create_plan think deeply about .strategic-claude-basic/research/[filename]`

Then wait for the user's input.

Process Steps

Step 1: Context Gathering & Initial Analysis

  1. Read all mentioned files immediately and FULLY:

    • Research documents (e.g., .strategic-claude-basic/research/[filename].md)
    • Related implementation plans
    • Any JSON/data files mentioned
    • IMPORTANT: Use the Read tool WITHOUT limit/offset parameters to read entire files
    • CRITICAL: DO NOT spawn sub-tasks before reading these files yourself in the main context
    • NEVER read files partially - if a file is mentioned, read it completely

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.

plan is a command published in the GitHub repository Fomo-Driven-Development/strategic-claude-base (2 stars, last pushed 9mo ago), licensed MIT. It adds 10 tokens to every session and 4,513 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
