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 | $0.00067 | $0.00977 |
| Opus 5 | $0.00034 | $0.00489 |
| Sonnet 5 | $0.00013 | $0.00195 |
| Haiku 4.5 | $0.00007 | $0.00098 |
Grade A, and why
market-to-devs-sell-to-buyers 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Market to devs, sell to buyers
The developer who adopts your tool is almost never the person who pays for it. Win the developer's heart; then hand them the ammunition to win the budget conversation for you.
Use this when: you have stars, signups, and a beloved free tier, and a revenue line of zero.
The core idea (Czakon)
Market to developers, sell to decision-makers. Developers evaluate and adopt; buyers (CTO/VP/procurement) approve money. Your growth engine is the developer champion who sells internally, so your job is to make them look smart to their boss.
Framework: GTM models that work (Czakon)
Pick the one that fits your product and ICP; don't run all four half-heartedly.
| Model | Fits when | The motion |
|---|---|---|
| Open source | infra/dev-tool, trust & inspectability matter | OSS core → adoption → paid cloud/enterprise |
| PLG / self-serve | fast time-to-value, dev = buyer for small teams | free tier → usage → expand → sales-assist on big accounts |
| Inbound | you can own the problem's content/SEO | educate on the problem → capture → nurture |
| Sales-led / ABM | high ACV, complex enterprise, few big logos | target named accounts, land via a dev champion |
Most dev tools are PLG + a sales-assist overlay for the accounts worth a human.
Framework: enable the champion (Czakon + Frankl)
Give the developer what they need to sell up:
- The Kairos case for their boss (weeks off a release cycle, risk reduced), see
value-prop-that-converts. - A one-pager / ROI snippet they can paste into an internal thread.
- Security/compliance answers the buyer will ask (SOC 2, data handling), the CTO's real fears.
- Proof: attributed results from peers at comparable companies.
Persona → sale map (Frankl): Alpha Dev finds & advocates → VPE/SRE validate feasibility → Empowered CTO approves budget → procurement handles terms (late, enterprise only). A complex sale needs a "what's in it for me" for each. Nail one persona and you get great meetings and no decisions.
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.

market-to-devs-sell-to-buyers is a skill published in the GitHub repository AIDevGTM/gtm-cofounder (276 stars, last pushed 5d ago), licensed MIT. It adds 67 tokens to every session and 977 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.
