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 | $0.00042 | $0.00801 |
| Opus 5 | $0.00021 | $0.00400 |
| Sonnet 5 | $0.00008 | $0.00160 |
| Haiku 4.5 | $0.00004 | $0.00080 |
Grade A, and why
idea-validator 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Idea Validator - Startup Idea Assessment Framework
Rigorously assess startup ideas BEFORE building using structured validation—saving months of wasted effort on ideas that won't work.
Hexa's Principle: "You want to make something people want. But people don't always know what they want—so you need to understand what they actually need."
When This Activates
- User asks "is this a good idea"
- User says "I want to build X" without validation
- User asks "should I pursue this"
- User mentions a startup idea they're considering
- User wants to know if their idea is worth building
The Framework
Validation = Opportunity Memo Assessment + Perceived Created Value (PCV) Score
Problem Assessment Matrix
| Dimension | Rating | Impact |
|---|---|---|
| Frequency | [Daily/Weekly/Monthly] | High/Med/Low |
| Severity | [Critical/Important/Nice-to-have] | High/Med/Low |
| Awareness | [Actively seeking/Aware/Unaware] | High/Med/Low |
| Budget | [Has budget/Would find/No budget] | High/Med/Low |
Problem Score: 3-4 High = Strong. 1-2 = Weak. 0 = Not a real problem.
PCV Scoring (4 Dimensions)
Rate current solution problems + your improvement:
| Dimension | Current Problem | Your Improvement |
|---|---|---|
| Price | Not a problem / A problem / Serious | No diff / Some / Serious |
| Quality | Not a problem / A problem / Serious | No diff / Some / Serious |
| Performance | Not a problem / A problem / Serious | No diff / Some / Serious |
| Convenience | Not a problem / A problem / Serious | No diff / Some / Serious |
Scoring: a=0, b=1, c=3 points. Sum all 8 ratings.
| Score | Interpretation | Recommendation |
|---|---|---|
| 0-6 | Weak | Don't pursue |
| 7-12 | Moderate | Needs refinement |
| 13-18 | Strong | Worth pursuing |
| 19-24 | Exceptional | Build NOW |
Quick Discovery Questions
Problem Space:
- What specific pain point does your ICP feel?
- How do they currently solve this?
- What's wrong with current solutions?
- How often do they experience this pain?
- What does this problem cost them?
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.

idea-validator is a skill published in the GitHub repository HK-hub/AgentSkills (6 stars, last pushed 25d ago), licensed MIT. It adds 42 tokens to every session and 801 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 2026-09-03.
