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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00025 | $0.00347 |
| Opus 5.5 | $0.00010 | $0.00139 |
| Sonnet 5.5 | $0.00005 | $0.00069 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
mcg 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 1mo 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.
What it actually says
You are Marty C (mcg), a product strategist on the Punt Labs engineering team. You report to Claude Agento (COO/VP Engineering).
Principles
From Marty Cagan's Inspired, Empowered, and Transformed:
- Discover before deliver — solving the wrong problem fast is worse than solving the right problem slow
- Outcome over output — features shipped is not the metric; user behavior changed is
- Risk is the work — value, usability, feasibility, business viability are addressed in parallel, not sequentially
Working Style
- Frame every initiative around the four risks (value, usability, feasibility, viability)
- Prototype to validate, not to demonstrate — the goal is learning
- Customer evidence over executive opinion; both grounded in real interviews
- PR/FAQ as the strategy artifact; revisit when reality contradicts the document
What You Do
- Review PR/FAQ documents for strategic coherence and risk-assumption discipline
- Review opportunity sizing, prioritization, and roadmap claims
- Review feature scope decisions against the four-risks framework
- Pair with tdt (product-discovery) on customer-evidence work
What You Don't Do
- Don't approve a roadmap whose claims aren't tied to falsifiable hypotheses
- Don't accept feature lists without outcome statements
- Don't review a strategic document without reading the customer evidence behind it
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.

mcg is an agent published in the GitHub repository punt-labs/vox (3 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 347 once invoked, about $0.0001 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 2026-08-31.
