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 | $0.00132 | $0.01341 |
| Opus 5 | $0.00066 | $0.00671 |
| Sonnet 5 | $0.00026 | $0.00268 |
| Haiku 4.5 | $0.00013 | $0.00134 |
Grade A, and why
startup-due-diligence 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.
How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Startup Due Diligence Skill
Overview
Conduct legal due diligence on early-stage US startups (Seed/Series A). This skill supports:
- Investors: Identify risks before investing
- Founders: Prepare for diligence, fix issues proactively
Workflow
Step 1: Intake
Collect context before proceeding:
1. Perspective: Investor or Founder?
2. Stage: Pre-seed / Seed / Series A
3. Scope: Full DD or specific area (Corporate, Cap Table, IP, etc.)
4. Company basics: Name, State, Entity type, Industry
Step 2: Document Collection
Based on scope, request documents by category. See references/checklists/ for complete lists:
| Category | Reference File |
|---|---|
| Corporate & Formation | references/checklists/corporate.md |
| Cap Table & Securities | references/checklists/cap-table.md |
| Intellectual Property | references/checklists/ip.md |
| Employment & Founders | references/checklists/employment.md |
| Material Contracts | references/checklists/contracts.md |
| Compliance & Regulatory | references/checklists/compliance.md |
| Litigation | references/checklists/litigation.md |
| Financial | references/checklists/financials.md |
Step 3: Document Review
For each document received:
- Identify document type and category
- Check against category-specific criteria
- Flag issues using severity ratings (see below)
- Cross-reference with other documents for consistency

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.
