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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.03603 |
| Opus 5 | $0.00010 | $0.01801 |
| Sonnet 5 | $0.00004 | $0.00721 |
| Haiku 4.5 | $0.00002 | $0.00360 |
Grade A, and why
pyright 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 9d 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.

Pyright - Fast Python Type Checker
progressive_disclosure: entry_point: summary: "Fast Python type checker from Microsoft with VS Code integration and strict modes" when_to_use: - "When needing faster type checking than mypy" - "When using VS Code (Pylance)" - "When requiring stricter type checking" - "When migrating from mypy" quick_start: - "npm install -g pyright" - "Create pyrightconfig.json" - "pyright ." token_estimate: entry: 65-80 full: 3500-4500
Installation
Node.js (Recommended)
# Global installation
npm install -g pyright
# Per-project installation
npm install --save-dev pyright
# Verify installation
pyright --version
VS Code (Pylance)
Pyright powers Pylance extension:
# Install Pylance extension (includes pyright)
code --install-extension ms-python.vscode-pylance
pip Installation
# Community wrapper
pip install pyright
# Note: Still requires Node.js runtime

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pyright is a skill published in the GitHub repository bobmatnyc/claude-mpm-skills (75 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 3,603 once invoked, about $0.0001 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 2026-09-03.
