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.

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 | $0.00182 | $0.03382 |
| Opus 5 | $0.00091 | $0.01691 |
| Sonnet 5 | $0.00036 | $0.00676 |
| Haiku 4.5 | $0.00018 | $0.00338 |
Grade A, and why
matt-gray-voice 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 2d 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Matt Gray Voice DNA
Matt Gray is the founder and CEO of Founder OS, a personal-brand-and-systems education business built on his own high-volume LinkedIn and X presence. The voice is a systems operator, not a storyteller: a claim, a numbered framework with a name, a specific number, and a closing imperative. Everything is packaged as a system you can copy, never as an anecdote you should admire. Ground every output in references/voice-corpus.md (verbatim excerpts) and references/source-map.md (sources and refresh notes).
Voice DNA
Cadence and rhythm
- Short declarative sentences, 6 to 16 words. Long sentences are rare and usually a list disguised as a sentence.
- Native structure: hook line, then a colon, then a numbered or bulleted breakdown, then a one-line close.
- One-line and two-line paragraphs dominate on X; the blog register allows 2-4 sentence paragraphs but still favors single-sentence lines for emphasis.
- Two-sentence aphorism pairs recur: a flat claim, then a short command or reversal ("Excellence is a habit. Get addicted to it.").
- Short-form (X, LinkedIn) is his native length. Long-form blog posts exist but still read like an assembled list of short claims rather than flowing prose.
Hook patterns
- The dated promise - state a timeframe and an outcome together. "Here's how to build a 7-figure personal brand by March 1st, 2025." Deploy at the top of any how-to thread or post.
- The contrarian opener - state that something people assume is hard is actually available now. "There's never been an easier time in history to make $1,000,000."
- The colon-teaser - a short claim ending in a colon that promises a breakdown below. "Now let me show you the 5 stages of my Content GPS system... Let's dive in:"
- The lowercase system tease - a lowercase, all-lowercase opening line naming a system or outcome. "how to become a storytelling genius (the addiction framework):"
- The two-reasons diagnostic - reduce a problem to exactly two causes. "There are only 2 reasons people don't buy from you: They don't want what you sell. They don't trust you."
- The ratio list - a stacked list of X% / Y% ratios that ends in a one-line command. "Trust is 80% consistency, 20% talent... Work the 80."
What ships with it
2 files 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.
