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.

Fable 5.1 $0.02132 $0.02132
Opus 5.5 $0.00853 $0.00853

Security

Grade A, and why

skills CLAUDE.md 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 6d 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.

Origin

This is a copy

95% identical to skills AGENTS.md — 4 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.

Project Overview

This repository is a plugin marketplace for Codex, Claude Code and OMP. It contains eight plugins for software development and personal productivity workflows:

  • core – memory, commit hygiene, refactoring, prompt refinement and branch review
  • web – CSS, React, Tailwind, testing, refactoring and design practices
  • typescript – strict, schema-first TypeScript guidance
  • system-design – Mermaid diagram generation from code
  • product-management – PRD creation, status updates and task orchestration
  • app – Swift iOS testing, App Intent-first development and SwiftUI architecture
  • principle – independent principle-* engineering skills
  • life – personal life management with the GPS method for goal achievement

Plugin Architecture

A plugin can contain three types of content:

  1. Agents – autonomous subprocesses with specialised tools and context, defined in agents/*.md.
  2. Skills – knowledge bases that load into context, defined in skills/*/SKILL.md.
  3. Commands – slash commands for quick actions, defined in commands/*.md.

Each harness has its own marketplace catalogue. Each plugin has one manifest per harness. Discovery differs by harness:

  • The Claude Code and OMP catalogues list the explicit skill paths of each plugin. Keep the OMP catalogue and the OMP plugin manifests identical to the Claude Code copies.
  • The Codex catalogue lists plugin sources only. Each Codex plugin manifest declares the skills directory.

Do not assume that the invocation syntax is the same in each harness. Validate each target harness.

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.
