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 | $0.00074 | $0.01421 |
| Opus 5 | $0.00037 | $0.00711 |
| Sonnet 5 | $0.00015 | $0.00284 |
| Haiku 4.5 | $0.00007 | $0.00142 |
Grade A, and why
time-to-first-value 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 12d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Time to first value (get them to the first win)
For a dev tool, the product is the pitch. A developer tries it alone and decides in minutes. Acquisition without activation is just a faster way to lose people.
Use this when: people sign up or star the repo and then nothing, they get it working once and never come back, your docs assume the reader already understands it, or you are about to spend on a launch or a channel while the first ten minutes still leak.
The core idea
You can nail your positioning, your homepage, and your launch, and still lose everyone in the first ten minutes. For a dev tool the first run is the sale: the developer tries it, alone, without talking to you, and decides. Two gates, straight from Frankl's DREAM funnel:
- Evaluation: can they get it working over a weekend, with zero human help? (the weekend test)
- Activation: how fast do they reach their first real win, the "I'm awesome" moment (time to first value)?
Fix this before you scale acquisition. Pouring users into a leaky first run just loses them faster, and know-if-its-working will show you that retention, not signups, is the number that matters.
The two thresholds
The weekend test (Frankl). A motivated developer should get your product doing something real over a weekend, without a call, a demo, or an email to you. If they cannot, that is your single highest-leverage work, above any channel, launch, or homepage tweak.
Time to first value (Czakon: "time to Hello World"). Measured in minutes, not hours, and the first meaningful win in the same sitting, not after an onboarding call next Tuesday. The first "Hello World" should be minutes in; the first real "oh, this is useful" should be that same session.
The win belongs to the developer, not your product (Frankl: the developer is the hero). The aha is "look what I just did," not "look what our platform can do." Design the first run so the developer feels capable, fast.
Framework: the friction log (Czakon)
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.

time-to-first-value is a skill published in the GitHub repository AIDevGTM/gtm-cofounder (274 stars, last pushed 4d ago), licensed MIT. It adds 74 tokens to every session and 1,421 once invoked, about $0.0004 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.
