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 | $0.00098 | $0.05286 |
| Opus 5 | $0.00049 | $0.02643 |
| Sonnet 5 | $0.00020 | $0.01057 |
| Haiku 4.5 | $0.00010 | $0.00529 |
Grade A, and why
solution-interview 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.
How it starts
The opening of the file, as written. The whole thing — 760 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solution Interview
Test if your solution actually solves the validated problem before building the full product. Master the art of showing concepts and prototypes to get honest feedback on solution fit.
When to Use This Skill
- After problem interviews to test if your solution addresses validated problems
- Before building MVP to validate core value proposition
- Prototype testing to get feedback on concepts and mockups
- Feature validation to test if new features solve real problems
- Pivoting to test alternative solutions to the same problem
- Pricing discovery to understand willingness to pay
Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Cindy Alvarez - "Lean Customer Development" (2014), Steve Blank - Customer Development |
| Core Principle | "Show, don't tell. Let customers react to something tangible. Their reactions—not their words—reveal the truth." |
| Why This Matters | People can't accurately predict their behavior. By showing a prototype and observing reactions, you get real signal about whether your solution works. |
What Claude Does vs What You Decide
| Claude Does | You Decide |
|---|---|
| Structures production workflow | Final creative direction |
| Suggests technical approaches | Equipment and tool choices |
| Creates templates and checklists | Quality standards |
| Identifies best practices | Brand/voice decisions |
| Generates script outlines | Final script approval |
What This Skill Does
- Structures solution demos - How to present concepts effectively
- Captures honest reactions - Gets real feedback, not politeness
- Identifies gaps and issues - What's missing or wrong
- Tests willingness to pay - Early pricing validation
- Measures solution fit - Does this actually solve the problem?
- Generates product insights - What to build, what to skip
How to Use
Prepare Solution Interview Script
I've validated this problem: [problem]
My proposed solution: [solution concept]
Create a solution interview script to test fit.
Include how to demo and what reactions to look for.
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.

solution-interview is a skill published in the GitHub repository guia-matthieu/clawfu-skills (149 stars, last pushed 5mo ago), licensed MIT. It adds 98 tokens to every session and 5,286 once invoked, about $0.0005 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 2026-09-03.
