"How to find leads for your writing biz" — Mitch Harris / Ship30for30

Why this is in the vault

A single reusable framework — prospect on buying signals, not company size — plus a copy-paste agent prompt (structured output schema, explicit anti-hallucination constraint, built-in self-critique follow-up) that's portable well beyond freelance writers.

The core argument

Mitch pivots the newsletter's usual Claude-centric framing to cover OpenAI's new ChatGPT Work agent, but the actual insight is content-agnostic: don't ask an agent to "find me 25 companies to pitch" — ask it to find evidence of intent. A random large-company CEO (Prospect A) is a worse lead than a smaller-company CEO who just launched a podcast and is hiring a Head of Content (Prospect B), because B is already spending money/attention on the problem you solve.

The mechanics that make this transferable:

  1. The assignment, not the ask. The full prompt front-loads an ideal-client spec (client type, service, price, geography, size, industries, exclusions) before asking for output — the agent gets a brief, not a one-liner.
  2. A locked 12-field output schema per prospect (person, company, role, website, signal, signal date, source link, fit rationale, outreach angle, contact path, 1–10 score, score rationale) — forces structured, auditable output instead of prose.
  3. An explicit anti-hallucination constraint: "Do not guess facts, contact information, or email addresses. Exclude any prospect unless you can provide evidence supporting the recommendation."
  4. A mandatory second pass — a follow-up "critique this list, replace weak prospects, don't prioritize fame over evidence" prompt — treats the first output as a draft to be interrogated, not a deliverable.

The self-promo hook: a "ChatGPT Work For Writing Businesses" live bootcamp (6 sessions / 2 weeks, waitlist CTA) sits at the top and bottom of the email. The framework and prompt are given away in full regardless of signup — genuinely extractable, not a teaser.

Mapping against Ray Data Co

The anti-hallucination constraint and the mandatory second-pass critique are the same discipline RDCO already codified independently, for a different reason: the 2026-05-31 fabrication incident that produced the "No-batched-result-declaration" hard rule (never declare a result in the same turn as the commands that determine it; default to "unknown"), and the /verify-dispatch skill's requirement that every dispatch prompt carry a pre-registered, objectively-checkable acceptance contract. Mitch's prompt arrives at the identical pattern — force the agent to show its evidence per-claim and then have it argue against its own output — from the sales-prospecting side rather than the agent-reliability side. That convergence is worth noting: "don't let the agent's first answer be the answer" is a general agentic-workflow rule, not RDCO-specific tooling.

Concretely usable: the buying-signal prospect framework (evidence of intent > company size/fame) maps directly onto two live RDCO surfaces — phData business-development research (which named accounts/stakeholders are showing signals of needing CAF/data-fabric work, vs. just being big logos) and the /discover-sources skill's niche/source discovery, which already looks for adjacent-discipline signal rather than raw prominence. The 12-field locked schema is a cleaner acceptance-contract template than what either currently specifies and is worth stealing verbatim for a future dispatch-prompt revision.

⚠️ Sponsorship

Self-promotion, not a third-party sponsor. Ship30for30 is pitching its own paid live bootcamp ("ChatGPT Work For Writing Businesses," waitlist-gated, no price disclosed) at both the top and bottom of the email. The framework and full prompt are given away in the body regardless of signup, so the bias risk is low — the technique isn't gated behind the CTA — but the piece exists to drive bootcamp waitlist signups and should be read as a lead magnet for that offer.
