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 | $0.00164 | $0.04843 |
| Opus 5 | $0.00082 | $0.02422 |
| Sonnet 5 | $0.00033 | $0.00969 |
| Haiku 4.5 | $0.00016 | $0.00484 |
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 — 496 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Offer Design
The skill that turns "I do coaching" into a package a buyer can say yes to. An offer is more than a price. It is the contract between what the buyer wants and what the seller can deliver inside a real container of time, scope, and money.
Bad offers overpromise (12 months of unlimited access for $500) or underpromise (a vague "consulting engagement" with no timeline) or are unsellable because they ask the buyer to figure out scope themselves. Good offers fit on a single page, can be quoted in one sentence, and survive 30 days of real client work without the founder regretting the math.
When this skill triggers
- "Design my offer"
- "Package my service"
- "What should I sell"
- "Scope my engagement"
- "Build my package"
- "Structure my service"
- "How do I price this engagement"
- "I keep saying yes to scope creep"
- "My clients keep asking for more"
- "I do not know what to charge"
- Auto-activated when assessment Section 6 (Offer + ICP) is incomplete or contains vague offer language
- Auto-activated when assessment Goal Section 9 contains "first offer", "first paying client", "launch", "package my service"
NOT for: pricing the offer (use pricing-strategy after offer locks). NOT for: positioning (use positioning first). NOT for: writing the sales page (use copywriting after offer locks). NOT for: building the proposal document (use proposal-writer after offer locks).
What an offer is
An offer is a 6-part package. All 6 parts must be specific. Missing any part creates scope ambiguity, which kills close rate and creates client regret.
The 6 parts of an offer
- Deliverable. What the buyer receives.
- Scope. What is included AND what is explicitly NOT included.
- Timeline. When work starts, milestones, and end date.
- Price + structure. Total price, payment terms, refund policy.
- Guarantee. What the seller promises and what happens if it does not happen.
- The "not for you" line. Who should NOT buy this offer.
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.
