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 | $0.00035 | $0.02087 |
| Opus 5 | $0.00017 | $0.01043 |
| Sonnet 5 | $0.00007 | $0.00417 |
| Haiku 4.5 | $0.00003 | $0.00209 |
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.
How it starts
The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Startup Ideation
Scope
Covers
- Turning vague "startup ideas" into structured opportunity theses
- Expanding your information diet to find off-the-beaten-path opportunities
- Running a Why Now analysis based on technology + behavior + distribution shifts
- Identifying tarpits (ideas that look good but are structurally hard) and pruning early
- Scoring ideas and producing a top-idea 1‑pager + 2‑week validation plan
When to use
- "Help me come up with startup ideas in/around ."
- "We have 5 ideas — help us pick one and explain why."
- "What’s a good Why Now for this idea?"
- "Pressure to do AI — where are real new opportunities?"
- "How do we avoid idea tarpits and pick something differentiated?"
When NOT to use
- You already chose an idea and need a delivery-ready PRD (use
writing-prdsorworking-backwards) - You need to define the problem space for a specific user pain (use
problem-definition) - You need to execute research (recruit, interview, synthesize) rather than frame it (use
conducting-user-interviews) - You need market sizing / pricing / fundraising pitch materials (adjacent work, not covered here)
- You already have a product but it is stuck or growth stalled and you are considering a direction change (use
startup-pivoting) - You have a launched product and need to measure whether you have product-market fit (use
measuring-product-market-fit) - You want to evaluate trade-offs between a small set of known options, not generate new ideas (use
evaluating-trade-offs)
Inputs
Minimum required
- Founder/team context + constraints (time, budget, skills, regulatory constraints)
- The decision to make + timeline (e.g., "pick 1 idea to validate in the next 2 weeks")
- Target customer type (B2B/B2C; any preferred industries or segments)
- Any starting ideas (even rough) + what prompted them
Missing-info strategy
- Ask up to 5 questions from references/INTAKE.md.
- If still missing, proceed with explicit assumptions and list Open questions that could change the recommendation.

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.

startup-ideation is a skill published in the GitHub repository liqiongyu/lenny_skills_plus (52 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 2,087 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.

plan
Use when a request needs shaping before any code is written — a rough or vague prompt to sharpen, an ambiguous idea to design, or a clear-enough task to decompose. One chain-starter that amplifies the prompt, designs the approach, and decomposes it into a batched task file, skipping whichever phases the request…
