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 | $0.01999 |
| Opus 5.5 | $0.00017 | $0.00800 |
| Sonnet 5.5 | $0.00009 | $0.00400 |
| Haiku 4.5 | $0.00004 | $0.00200 |
Grade A, and why
extract-startup-ideas 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 1mo 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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You read the CS183B "How to Start a Startup" lecture transcripts and extract the startup ideas / company case studies that the speakers (Sam Altman, YC partners, founders of Airbnb, Stripe, Facebook, a16z, Peter Thiel, etc.) use as teaching examples.
Goal
Turn the 20 lectures into a clean, browsable atlas of startup case studies. Each card is one company, with five fixed fields, rendered into a polished HTML page using the shared template.
Use the HTML template in:
template/index.html
Do not invent a new layout. Only replace the top-level placeholders and repeat the case card block.
INPUT
Source transcripts:
course/transcripts/Lecture01-.md … course/transcripts/Lecture20-.md
Twenty files, ~150 KB total. Plain Markdown, one lecture per file.
If the user passes a scope argument when invoking the skill (e.g. "Airbnb only", "Lecture 4 only", "just the manual-work pattern"), treat it as a filter on which companies to extract. With no scope, extract every company that gets a real narrative (not just a name-drop).
OUTPUT FILE
Write the rendered HTML to:
course/notes/startup-ideas-{scope_slug}.html
Rules:
scope_slug: short lowercased slug describing the scope. For the default "all companies, all lectures" output, usecs183b-all. For a filter, derive a short kebab-case slug (e.g. "Airbnb only" →airbnb, "Lecture 4" →lecture-04, "manual work pattern" →manual-work).- Create the
course/notes/directory if it doesn't exist.
Example: course/notes/startup-ideas-cs183b-all.html
Do NOT paste HTML into chat. The chat response should only say:
Created course/notes/{filename} — {N} companies across {L} lectures.
CARD SELECTION
A company qualifies as a card when the speaker uses it as a story — describing what the company did early, why it worked, or what lesson it teaches.
Include:
- Companies whose founding story, early scrappiness, or specific tactic is described
- Companies used to illustrate a named principle (e.g. "do things that don't scale")
- Companies whose later outcome the speaker explicitly references
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.

extract-startup-ideas is a skill published in the GitHub repository 0-bingwu-0/html-knowledge-base-templates (5 stars, last pushed 5mo ago), licensed MIT. It adds 43 tokens to every session and 1,999 once invoked, about $0.0002 per session on Opus 5.5. 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.
