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 | $0.00041 | $0.01502 |
| Opus 5 | $0.00020 | $0.00751 |
| Sonnet 5 | $0.00008 | $0.00300 |
| Haiku 4.5 | $0.00004 | $0.00150 |
Grade A, and why
offer-design 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 6d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Offer Design
"40 hours of consulting" is a body for rent, and a body is priced against every other body. An offer is an outcome with a boundary: what the buyer gets, when it is done, and what is explicitly not in it. The boundary is not fine print — it is the part that makes the price defensible and gives the Delivery Lead something to enforce six weeks later.
This skill also produces the positioning statement. The statement is an output, not an exercise; a sentence with nothing decided behind it is a slogan.
When to use
After icp-definition and before pricing-strategy. Also when the founder
describes what they do differently every time they're asked, when the
description contains the word "and" three times, or when scope keeps leaking on
delivery — an offer with no boundary cannot leak, because it had no shape.
Inputs
Read first, in order — house rule 1:
offer.md— the## ICPsection. If it is empty, stop and runicp-definition. An offer for nobody is a menu.clients/— what was actually delivered, and where the hours went that nobody paid for. Your exclusions are hiding in there.pipeline.md— what prospects asked for, and what they didn't understandmetrics.md— which engagement shape made money
Beliefs
- Nobody has ever bought competence. The buyer purchases a specific state of the world they cannot reach alone; the founder's twelve years make that credible, they do not make it valuable, and an offer built on the twelve years is selling the evidence instead of the claim.
- "We work bespoke" is almost never a service philosophy. It is a decision nobody made. Bespoke is the most expensive thing a company of one can sell — every proposal is a fresh invention — and the customisation the buyer actually valued was about a tenth of it.
- The offer the founder finds boring is usually the one worth selling. Interesting work is interesting because it is rare, and rare means there is no repeatable shape underneath it. Boredom measures how well-defined the thing has become, not what it is worth.
What ships with it
1 file 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.

offer-design is a skill published in the GitHub repository msolecki/founder-os (4 stars, last pushed 3d ago), licensed MIT. It adds 41 tokens to every session and 1,502 once invoked, about $0.0002 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 2026-08-31.
