qplan

qplan is a command for Claude Code from brianmontero18/dev-mcp-tools. It costs 0 tokens per session (315 once invoked), scanned A, original, MIT.

A command named "qplan" that examines a codebase and produces an implementation plan based on its existing patterns. A codebase is the collection of source files for a software project.

In plain words
What is it for?
It is for analyzing related implementations, checking architectural consistency, and outlining a minimal plan for new work.
Why use it?
It helps avoid unnecessary changes by finding similar code, reusable parts, and the conventions already used in the project.

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

qplan 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 3d 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.

What it actually says

QPLAN - Codebase Analysis & Planning

When user types "qplan", execute this workflow:

1. Codebase Analysis

  • 🔍 Analyze similar parts of the codebase
  • 📋 Review existing patterns and conventions
  • 🧩 Identify reusable components/utilities
  • 📐 Check architectural consistency

2. Plan Validation

Determine whether your plan:

  • Consistency: Follows existing codebase patterns
  • Minimal changes: Introduces least possible modifications
  • Code reuse: Leverages existing functions/components
  • Architecture: Maintains current system design

3. Tools to Use

  • Grep - Find similar implementations
  • Glob - Locate related files
  • Read - Study existing code patterns

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.
