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 | $0.01440 | $0.01440 |
| Opus 5 | $0.00720 | $0.00720 |
| Sonnet 5 | $0.00288 | $0.00288 |
| Haiku 4.5 | $0.00144 | $0.00144 |
Grade A, and why
claude-mpm-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 11d 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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Instructions for claude-mpm-skills Project
⚠️ CRITICAL: This is a SKILLS REPOSITORY
This project develops skills for the Claude MPM Skills Repository, NOT for local use.
Skills are:
- Developed in
toolchains/oruniversal/directories - Built using
scripts/generate_manifest.py - Deployed via
scripts/flatten_skills.shto.claude/skills/(gitignored)
DO NOT create skills directly in .claude/skills/ - that's the deployment target, not the source!
Skill Creation Workflow
Step 1: Initialize New Skill
Use the init script (recommended):
# Interactive mode
python scripts/init_skill.py
# Toolchain skill (e.g., PHP framework)
python scripts/init_skill.py --path toolchains/php/frameworks/espocrm
# Universal skill
python scripts/init_skill.py --path universal/testing/integration-patterns
# With description
python scripts/init_skill.py --path toolchains/python/async/celery --description "Celery task queue patterns"
# Dry run to preview
python scripts/init_skill.py --dry-run --path toolchains/go/testing/integration
Step 2: Skill Directory Structure
Skills are organized hierarchically in the repository:
claude-mpm-skills/
├── toolchains/ # Language/framework-specific skills
│ ├── python/
│ │ ├── frameworks/
│ │ │ └── django/
│ │ │ ├── SKILL.md
│ │ │ ├── metadata.json
│ │ │ └── references/ # Optional deep-dive docs
│ │ └── testing/
│ │ └── pytest/
│ └── php/
│ └── frameworks/
│ └── espocrm/ # ← Example: EspoCRM skill location
│ ├── SKILL.md
│ ├── metadata.json
│ └── references/
├── universal/ # Cross-language skills
│ ├── testing/
│ │ └── tdd-patterns/
│ └── architecture/
│ └── api-design/
└── manifest.json # Auto-generated - DO NOT edit manually
Step 3: Required Files
Each skill directory must contain:

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.
- 11d ago First seen · 223 lines · 1,440 tokens per session scan A 04c6755d9d8f
claude-mpm-skills CLAUDE.md is an instructions file published in the GitHub repository bobmatnyc/claude-mpm-skills (74 stars, last pushed 1mo ago), licensed MIT. It adds 1,440 tokens to every session, about $0.0072 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.
