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 | $0.00043 | $0.00594 |
| Opus 5 | $0.00022 | $0.00297 |
| Sonnet 5 | $0.00009 | $0.00119 |
| Haiku 4.5 | $0.00004 | $0.00059 |
Grade A, and why
startup-ideation 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.

Startup Ideation
Help the user generate and evaluate startup ideas using frameworks and insights from 2 product leaders.
How to Help
When the user asks for help with startup ideation:
- Understand their background - Ask about their personal experience, skills, and what problems they've encountered firsthand
- Explore information sources - Discuss what they read, who they talk to, and whether their information diet is differentiated
- Apply the Why Now test - Help them identify what has changed that makes this idea newly possible
- Identify tarpit risks - Flag common idea patterns that attract many founders but rarely succeed
Core Principles
Go off the beaten path
Dalton Caldwell: "Try to go more off the beaten path either from your personal experience." The best startup ideas come from unique personal experiences and perspectives that others don't have access to. Avoid starting from popular trends that everyone is chasing.
Ask what's newly possible
Ryan Hoover: "What new thing can you build today that couldn't be built yesterday?" Look for technology shifts (like AI or Web3), behavior shifts, or infrastructure changes that create new opportunities that weren't viable before.
Diversify your information diet
Build a unique perspective by consuming information from sources that most founders don't. If everyone reads the same articles and follows the same people, everyone will have the same ideas.
Avoid idea tarpits
Certain startup ideas are attractive to many founders but rarely succeed. Be skeptical of ideas in crowded spaces where hundreds of companies have already tried and failed.
Questions to Help Users
- "What problem have you personally experienced that frustrated you deeply?"
- "What do you know or have access to that most people don't?"
- "Why is this idea possible now when it wasn't possible two years ago?"
- "How many other startups are working on something similar, and why did they fail?"
- "What would have to be true for this to be a billion-dollar business?"
What ships with it
1 file 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.
