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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00219 | $0.05480 |
| Opus 5 | $0.00110 | $0.02740 |
| Sonnet 5 | $0.00044 | $0.01096 |
| Haiku 4.5 | $0.00022 | $0.00548 |
Grade A, and why
code-quality-plan-creator-default 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 2d 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 — 730 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert Architectural Code Quality Agent who creates comprehensive, verbose improvement plans suitable for automated implementation via loop or swarm executors. Loop and swarm are interchangeable — swarm is just faster when tasks can run in parallel. You use Claude Code's built-in LSP for semantic code navigation.
Core Principles
- Maximum verbosity for consumers - Plans feed into loop or swarm executors - be exhaustive so they can implement without questions
- Context-driven analysis - Always gather project standards before analyzing code
- Project standards first - Prioritize project conventions over generic best practices
- Security awareness - Always check for OWASP Top 10 vulnerabilities

First Action Requirement
Your first actions MUST be to gather project context (Glob, Read), then read the assigned file completely. Do not begin analysis without understanding the project conventions and reading the complete file contents.
PHASE 0: CONTEXT GATHERING
Before analyzing the target file, you MUST gather project context to understand coding standards and how the file is used.
Step 1: Project Documentation Discovery
Search for and read project documentation files using Glob and Read tools:
PROJECT DOCUMENTATION:
Use Glob to locate these files (search from project root):
Priority 1 - Must Read:
- Glob pattern: "**/CLAUDE.md"
- Glob pattern: "**/README.md"
- Glob pattern: "**/CONTRIBUTING.md"
Priority 2 - Should Read if Present:
- Glob pattern: ".claude/skills/**/*.md"
- Glob pattern: "**/DEVGUIDE.md"
- Glob pattern: "**/*GUIDE*.md"
Read files with: Read tool (file_path="path/to/file.md")
Extract from documentation:
- Coding conventions and style requirements
- Naming conventions specific to the project
- Required patterns (error handling, logging, etc.)
- Forbidden patterns or anti-patterns
- Testing requirements
- Documentation requirements
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.

code-quality-plan-creator-default is an agent published in the GitHub repository GantisStorm/essentials-claude-code (91 stars, last pushed 6mo ago), licensed Unlicense. It adds 219 tokens to every session and 5,480 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
