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.

What it costs to keep this loaded
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 | $0.00059 | $0.00843 |
| Opus 5 | $0.00030 | $0.00421 |
| Sonnet 5 | $0.00012 | $0.00169 |
| Haiku 4.5 | $0.00006 | $0.00084 |
Grade A, and why
mvp-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 10d 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.

MVP Validator
Overview
This skill enables critical evaluation of Minimum Viable Products from an agile startup consultant perspective. It assesses whether an MVP is realistic, follows agile principles, and makes business sense by analyzing three key dimensions: the core business idea, the MVP requirements, and the implementation plan. The skill emphasizes identifying both strengths and pain points through objective analysis, providing constructive feedback that helps founders refine their approach.
When to Use This Skill
Activate this skill when users ask to:
- Review an MVP for realism and business viability
- Evaluate a startup idea and its implementation plan
- Validate if an MVP follows agile principles
- Provide feedback on MVP requirements and scope
- Assess the feasibility of a product vision
- Challenge assumptions in a startup plan
MVP Review Workflow
Phase 1: Idea Assessment
Examine the core business idea for:
- Problem Validity: Does a real problem exist? Is it significant enough to solve?
- Market Opportunity: Is the addressable market realistic? Who exactly is the target customer?
- Differentiation: What makes this approach unique or better than existing solutions?
- Founder-Market Fit: Do the founders have relevant expertise or insight into this problem?
Phase 2: Requirements Evaluation
Analyze the MVP requirements against agile principles:
- Scope Realism: Can these features realistically be built in the proposed timeline?
- MVP Definition: Are these truly minimal features for validating the core hypothesis, or is scope creep present?
- Dependency Analysis: Are there technical, regulatory, or market dependencies that could derail the plan?
- Priority Clarity: Which features are essential vs. nice-to-have? Are priorities defensible?
Phase 3: Plan Assessment
Evaluate the implementation plan:
- Timeline Realism: Are the estimates reasonable given team size and complexity?
- Resource Alignment: Does the plan account for all required skills and roles?
- Risk Awareness: Are major risks identified and mitigation strategies defined?
- Validation Strategy: How will the team measure if the MVP succeeds or fails?
What ships with it

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.

mvp-validator is a skill published in the GitHub repository maxvaega/awesome-skills (40 stars, last pushed 9d ago), licensed MIT. It adds 59 tokens to every session and 843 once invoked, about $0.0003 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 2026-08-30.
