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 | $0.00050 | $0.01149 |
| Opus 5 | $0.00025 | $0.00575 |
| Sonnet 5 | $0.00010 | $0.00230 |
| Haiku 4.5 | $0.00005 | $0.00115 |
Grade A, and why
who-is-this-for 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 13d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Who is this for?
"Developers" is not a market. It's a medium. If your ICP doesn't exclude anyone, it isn't one.
Use this when: you describe your user as "developers" or "engineering teams," you can't name a person who is clearly not a fit, or you're aiming your messaging at the VP of Engineering because they have the budget.
The core idea
A usable ICP is specific enough that some people are obviously out. "Every developer" gives you nothing to say, because a message that speaks to everyone speaks to no one. Sharpen until exclusion is possible.
And in almost every AI/dev-tool sale there is more than one person: the developer who adopts is rarely the person who pays. Market to the adopter; sell to the buyer. Confuse the two and you get great meetings and no decisions.
Framework 1: The personas in the sale (Frankl)
Map who plays each role. You need all of them for a complex sale; skip one and the deal stalls.
| Persona | Cares about | Role in the sale |
|---|---|---|
| Alpha Dev | "What's possible?" Lives in the future. No budget. | Finds you, experiments, advocates internally, creates social proof |
| Empowered CTO | Kairos, weeks off a release cycle, competitive edge. Has budget. | Approves spend and strategic fit |
| VP Engineering | Team velocity, DX, quality at scale. Fears downtime/security | Evaluates feasibility, tests in staging |
| SRE / Platform Eng | Reliability, less toil. Reads your code before your copy. | Gatekeeps operational risk |
The Alpha Dev is not your long-term customer. They chase the next shiny thing. You need them anyway: they carry new tech to the people who pay.
Framework 2: Jobs to be done, not demographics (Czakon)
A job title is not actionable; a job is. Write it as:
When [situation], I want to [motivation], so I can [expected outcome].
Example: "When I inherit a service with no tests, I want to generate a safety net fast, so I can refactor without fear." That sentence tells you the trigger, the pain, and the win. A demographic never does.
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.
- 13d ago First seen · 81 lines · 50 tokens per session scan A 5daf250c91ea
who-is-this-for is a skill published in the GitHub repository AIDevGTM/gtm-cofounder (276 stars, last pushed 5d ago), licensed MIT. It adds 50 tokens to every session and 1,149 once invoked, about $0.0003 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.
