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 5.1 | $0.01131 | $0.01131 |
| Opus 5.5 | $0.00452 | $0.00452 |
| Sonnet 5.5 | $0.00226 | $0.00226 |
| Haiku 4.5 | $0.00113 | $0.00113 |
Grade A, and why
dotclaude AGENTS.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 22d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file provides guidance to Codex (Codex.ai/code) when working with code in this repository.
Repository Overview
This is a Codex plugin marketplace (frad-dotclaude) containing 21 plugins across development and productivity categories. Each plugin follows auto-discovery conventions—place components in commands/, agents/, skills/ directories and Codex discovers them automatically.
Active plugins: git, github, refactor, swiftui, office, lark, hyperframes, plugin-optimizer, mattpocock, superpowers, antigravity, pi, interfaces, storm, hardware, autoresearch, memory
Non-active plugins: acpx, code-context, utils, meeseeks-vetted
Plugin Structure
plugin-name/
├── .Codex-plugin/plugin.json # Manifest with commands/agents/skills/hooks
├── agents/*.md # Agent definitions
├── skills/skill-name/ # Skill directories
│ ├── SKILL.md # Main skill file (required)
│ └── references/ # Detailed reference materials
├── scripts/ # Utility scripts (bash/python)
└── examples/ # Example configurations
Skill registration determines visibility. A skill registered under "commands" in plugin.json becomes a user-invocable slash command (e.g., /git:commit). A skill registered under "skills" is internal-only, loaded automatically when Codex needs domain knowledge but never shown in /help. Example from refactor/:
"commands": ["./skills/refactor/"]-- user runs/refactor:refactor"skills": ["./skills/best-practices/"]-- loaded automatically during refactoring
Hooks can be inline in plugin.json. See git/.Codex-plugin/plugin.json for the PreToolUse hook pattern (runs a shell script to validate Bash tool calls before execution).
Development Workflow
Validation: Run /plugin-optimizer:optimize-plugin before committing. Alternatively:
# All checks (structure, manifest, frontmatter, tools, tokens)
python3 plugin-optimizer/scripts/validate-plugin.py <plugin-path>
# Specific checks only
python3 plugin-optimizer/scripts/validate-plugin.py <plugin-path> --check=manifest,frontmatter
# JSON output for scripting
python3 plugin-optimizer/scripts/validate-plugin.py <plugin-path> --json
# Verbose (shows passing checks too)
python3 plugin-optimizer/scripts/validate-plugin.py <plugin-path> -v
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.

dotclaude AGENTS.md is an instructions file published in the GitHub repository FradSer/dotclaude (593 stars, last pushed 7d ago), licensed MIT. It adds 1,131 tokens to every session, about $0.0045 per session on Opus 5.5. 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 2026-09-24.
