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 | $0.00094 | $0.05185 |
| Opus 5 | $0.00047 | $0.02593 |
| Sonnet 5 | $0.00019 | $0.01037 |
| Haiku 4.5 | $0.00009 | $0.00519 |
Grade A, and why
customer-discovery 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.

Customer Discovery
Systematically validate your business hypotheses before building anything. Master Steve Blank's Customer Development methodology that became the foundation of Lean Startup and YC's approach.
When to Use This Skill
- Starting a new venture to avoid building something nobody wants
- Before writing a line of code to validate problem-solution fit
- Pivoting decisions to systematically test new directions
- Early-stage fundraising to prove market validation
- Product roadmap planning to prioritize based on validated customer needs
- Entering new markets to understand unfamiliar customer segments
Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Steve Blank - "The Four Steps to the Epiphany" (2005) |
| Core Principle | "No business plan survives first contact with customers. Get out of the building." |
| Why This Matters | Startups fail because they build products nobody wants. Customer Discovery replaces guessing with systematic learning before you run out of money. |

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.
