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 | $0.00073 | $0.00748 |
| Opus 5 | $0.00036 | $0.00374 |
| Sonnet 5 | $0.00015 | $0.00150 |
| Haiku 4.5 | $0.00007 | $0.00075 |
Grade A, and why
founders-playbook-router 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 12d 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.

Founder Playbook Router
Overview
Use this skill to classify the founder's current company stage, choose the right stage skill, and run a short guided intake when the founder has not provided enough context.
The stage skills are listed below. If the agent supports $skill invocation, the names can also be invoked with a $ prefix.
ai-native-idea-stage: validate a problem, customer, wedge, and AI-native opportunity.ai-native-mvp-stage: scope, build, evaluate, and harden the first useful product.ai-native-launch-stage: position, sell, onboard, price, and learn from early customers.ai-native-scale-stage: turn early traction into repeatable GTM, operating cadence, team, and metrics.
Router Workflow
- Read the founder's current context.
- If the context is thin, run the guided intake below before making a confident recommendation.
- Classify the stage using the stage rules below.
- If the stage is clear, invoke or recommend the matching stage skill.
- If two stages are plausible, choose the earlier stage unless the founder already has evidence that satisfies its exit criteria.
- Return a concise stage diagnosis, the reason, the next stage skill, and the minimum input checklist.
Guided Intake
Do not wait for the founder to provide a complete brief. If the request has fewer than three useful facts, ask up to five questions first.
Ask in one compact batch:
1. What are you building or considering?
2. Who is the specific customer or user?
3. What exists today: idea only, prototype, MVP, launched product, or traction?
4. What evidence do you have: interviews, users, revenue, retention, pilots, or none yet?
5. What output would help most right now: diagnosis, validation plan, MVP scope, launch plan, or scale plan?
After the user answers, infer the stage and proceed. If one answer is unclear, state the assumption and continue rather than asking another full intake.
Stage Rules
Choose Idea when the founder has a hypothesis but lacks strong customer evidence, a clear wedge, or a validated pain.
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.

founders-playbook-router is a skill published in the GitHub repository Hades-HY-LI/ai-native-founder-playbook-skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 73 tokens to every session and 748 once invoked, about $0.0004 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 2026-08-31.
