Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

warm-intro 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.

Warm introductions

A warm intro is the highest-converting way into an investor. This skill helps a founder (1) find who can introduce them and (2) write a forwardable, double opt-in intro that makes the connector's job effortless and the investor's decision easy.

Read shared/references/outreach-ethics.md first. The connector is spending their credibility for you — never make that costly or risky for them.

The core mechanic: double opt-in, forwardable

The gold-standard etiquette:

  1. You write a short note to your connector asking if they're willing to intro — and you include a forwardable blurb they can paste/forward as-is.
  2. The connector checks with the investor first ("can I intro you to X?") — double opt-in. This protects the connector and means the investor arrives warm, not ambushed.
  3. The connector forwards your blurb; the investor replies; you take it from there.

Your job is to make step 1 take the connector 30 seconds. The easier you make it, the more likely it happens — and the better it reflects on you.

Step 1 — Find the warm path

If the founder doesn't yet know who to target at the firm or who can introduce them, run the warm-path-finder skill first — it pinpoints the right person and ranks connection paths from the founder's own authorized data (Gmail, exported LinkedIn connections, contacts) and public sources. This skill takes over once a named introducer exists.

Before writing, help the founder figure out who can intro them:

  • Direct: do they already know someone at/near the firm?
  • Second degree: search LinkedIn for shared connections to the target partner; check who in their network knows portfolio founders (a portfolio founder's intro is gold — investors trust their founders).
  • Community paths: accelerator alumni, university/employer networks, angel syndicates, founder Slacks, mutual advisors.
  • Best connector ≠ most senior. The ideal introducer is someone the investor trusts and replies to and who genuinely rates you. A lukewarm intro from a big name is worse than an enthusiastic one from a respected peer.
