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 | $0.00088 | $0.05441 |
| Opus 5 | $0.00044 | $0.02721 |
| Sonnet 5 | $0.00018 | $0.01088 |
| Haiku 4.5 | $0.00009 | $0.00544 |
Grade A, and why
pricing-validation 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 9d 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.

Pricing Validation
Test willingness to pay before launching with proven pricing research methodologies. Combine Van Westendorp, Gabor-Granger, and behavioral techniques to find your optimal price point.
When to Use This Skill
- After solution validation to test willingness to pay
- Before launch to set initial pricing
- Pricing changes to test new price points
- New segments to understand price sensitivity by segment
- Competitive positioning to price against alternatives
- Feature pricing to understand value of add-ons
Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Van Westendorp PSM (1976), Gabor-Granger method, behavioral economics |
| Core Principle | "People can't accurately predict what they'd pay. Use structured methods to triangulate, and verify with real purchasing behavior." |
| Why This Matters | Pricing wrong costs you customers (too high) or money (too low). Every 1% improvement in price has 11% profit impact on average. |
What Claude Does vs What You Decide
| Claude Does | You Decide |
|---|---|
| Structures analysis frameworks | Strategic priorities |
| Synthesizes market data | Competitive positioning |
| Identifies opportunities | Resource allocation |
| Creates strategic options | Final strategy selection |
| Suggests implementation approaches | Execution decisions |
What This Skill Does
- Finds price range - Identifies acceptable pricing boundaries
- Tests price points - Measures demand at specific prices
- Identifies optimal price - Balances revenue and conversion
- Segments by willingness - Who will pay more vs. less
- Validates pricing model - Subscription vs. one-time vs. usage
- Reveals value perceptions - What drives pricing acceptance

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.
