YALC-the-GTM-operating-system: Skill for Claude Code

.claude/skills/prospect-discovery-pipeline/SKILL.md

prospect-discovery-pipeline is a skill for Claude Code from Othmane-Khadri/YALC-the-GTM-operating-system. It costs 97 tokens per session (1,457 once invoked), scanned A, original, MIT.

An end-to-end prospect-finding workflow based on one or two existing clients. It finds similar companies, filters them against your ideal customer profile, finds marketing leaders, adds business signals, and drafts two personalized LinkedIn messages per lead.

In plain words
What is it for?
Use it to build a lookalike target list, find contacts such as CMOs, enrich prospects with relevant signals, and prepare A/B-testable LinkedIn outreach.
Why use it?
It combines several research and outreach-preparation steps while pausing for review before costly work. It is intended for producing a campaign-ready group of prospects rather than looking up one company.

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

prospect-discovery-pipeline 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 13d 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.

Prospect Discovery Pipeline

End-to-end pipeline: PredictLeads lookalikes → ICP filter → Crustdata CMO finder → multi-signal enrichment → 2 LinkedIn variants drafted with per-lead personalization. Pauses for user review before any expensive operation. Always quotes credit cost up front.

When to use

  • Building a target account list anchored on 1–2 known clients
  • Generating a campaign-ready batch (10–25 leads with full signal context)
  • Producing 2 A/B-testable LinkedIn message variants tied to actual signal data per lead

Don't use when: ad-hoc lookup of one company (use predictleads-signals); just lookalike domains without contacts (use predictleads-lookalikes); enriching a list you already have qualified leads for (use signals:enrich --result-set directly).

The 5-phase flow

Always follow this order. Quote credit cost before each phase.

Phase 1 — Discovery (2 PL credits for 2 anchors)

npx tsx src/cli/index.ts signals:similar --domain anchor1.com --limit 50
npx tsx src/cli/index.ts signals:similar --domain anchor2.com --limit 50

Merge into a candidate pool, dedupe by domain. Expect 30–80 unique candidates per pair.

Phase 2 — ICP filter (FREE, pause for user review)

Hand-filter the pool against the user's ICP criteria:

  • Employee count (use Crustdata company_identify — FREE — only when judgement uncertain)
  • Industry vertical (back-office SaaS, commerce infra, HR-tech, etc.)
  • HQ region
  • Marketing maturity proxies (visible content investment)

STOP and present the 10 finalists to the user before spending more credits. Surface any obvious gaps or weak fits. Wait for explicit approval.

Phase 3 — CMO finder (3 Crustdata credits, batch)

Single batch search across all 10 companies:

filters = {
  op: 'and',
  conditions: [
    { column: 'current_employers.company_website_domain', type: 'in', value: ['10 domains'] },
    { column: 'current_employers.title', type: '[.]', value: 'Marketing' },
    { column: 'current_employers.seniority_level', type: 'in', value: ['CXO', 'Vice President', 'Director'] },
  ],
}
limit: 50

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.
