What it does

In the author's own words, from each skill's SKILL.md.

  • 00-gtm-router

    Plan and run the full API-first GTM chain - the orchestrator (step 00) that turns an ICP description plus optional budget, volume, and urgency into the right discovery -> qualification -> extraction -> signals -> judgment -> email-resolution sequence, with per-step cost estimates and rationale, then executes it skill-by-skill after a go-ahead. Use whenever a request spans more than one chain step…

  • 01-icp-qualify

    The qualification gate of the GTM chain - judges every discovered company against the client's ICP before any paid enrichment, so credits are spent only on companies that could actually buy. Works for any client and any vertical: it studies the client first, then compiles client-specific qualification criteria and applies them. Use whenever a prospect list needs cleaning before outreach or enrich…

  • 01-prospeo-discover

    B2B company discovery and list building via the Prospeo search API. Use when the user wants to find companies from an ICP, build a prospect or TAM list, search by ICP, or size a market - e.g. "build a list of B2B SaaS in the US", "how many companies match this ICP", "TAM sizing", "company search", or any mix of industry + location + headcount + funding filters. Handles seed-based "similar to X" r…

  • 01-prospeo-lookalike

    Seed-based B2B company discovery via the Prospeo company-lookalike API. Use when the user has example companies and wants more like them - "find companies similar to X", "companies like Stripe and HubSpot", "lookalikes of these domains", "we closed these 20 logos, find more", "expand this seed list", or hands over closed-won accounts / a competitor / a customer list and wants similar firmographic…

  • 02-apify-maps-discover

    Find local-business (SMB) prospects via Google Maps using the Apify Compass actor. Use for Zevenue Step-2 Discovery (Vertical) when the ICP is Maps-addressable - laundromats, salons, HVAC, yoga studios, gyms, clinics - and you need a normalized list of name, domain, address, phone, rating, and review count ready for enrichment. Estimates cost and prompts before any run over $10. Requires APIFY_AP…

  • 03-firecrawl-research

    Scrapes a company website into clean, page-typed markdown using Firecrawl map + scrape + extract. Triggers on: "scrape this company", "read their website", "extract pages from", "research this domain", "fetch their careers page", or any URL + "scrape/extract/read". Covers single domain, batch processing, structured LLM extraction, and Google Sheets output.

  • 04-crustdata-signals

    Enriches company domains with structured signals from CrustData - funding rounds, headcount growth, department growth, and recent hires. Use when the user wants to pull company signals, enrich domains with funding/growth/hiring data, check who recently joined a company, find new hires at a domain, get headcount trends, or anything involving CrustData enrichment. Also triggers on: "run crustdata s…

  • 04-theirstack-jobs

    Pulls open job postings from the TheirStack API and turns them into structured hiring signals - open roles per domain, titles, seniority, posting dates, hiring team, plus free firmographics (headcount, funding stage, industry). Step 04 (signals) of the API-first GTM chain, and the discovery entry for hiring-defined ICPs. Use when the user wants hiring signals, open reqs, job postings, "who is hir…

  • 05-signal-builder

    Rank a prospect's outbound signals and pick the campaign approach (Pain-led / Value-led / Segment fallback) - the judgment layer (step 05) of the API-first GTM chain. Takes scraped website markdown (03-firecrawl-research), vendor signals like funding / headcount / recent hires (04-crustdata-signals), or just a URL or pasted content, and emits ranked provenance-backed signals: the exact quotable s…

  • 06-resolution-email-person

    Turn a company domain (plus an optional person name or job title) into a verified, send-safe email address - the deliverability-first "resolution" layer of a cold-email pipeline. Use when the user wants to find or verify a work email, enrich a list or file of domains into decision-maker contacts, or resolve "who is the [title] at [company] and what's their email." Works standalone or as Layer 06…

  • 07-campaign-sheet

    Turn a terminal records.jsonl into an owner-readable campaign sheet plus a HubSpot-import-shaped CSV - the chain's exit door. Use when a run is ready to hand to an owner: "build the campaign sheet", "export these for HubSpot", "who do I contact first", or as the final step of run-first-campaign. Reads whatever stage produced the records (qualified, signal-ranked, or fully resolved) and degrades g…

  • creative-variable

    Identify and spec non-obvious personalization variables for an outbound campaign - variable names, grammar forms, sources, extraction prompts, fallbacks, rendered examples. Use when building a new campaign's personalization layer or auditing existing copy against the four variable archetypes.

    skills/creative-variable/SKILL.md on GitHub (opens in a new tab)
  • email-writer

    Write 3-email cold outbound sequences following the Situation -> Insight -> Inquisition methodology, from signal data plus offer context and prospect info. Use to draft campaign copy after signal-builder or from enrichment data, with deliverability rules and a QA checklist enforced.

    skills/email-writer/SKILL.md on GitHub (opens in a new tab)
  • gtm-context

    Set up the GTM context layer - interviews you about your offer, ICP, and engagement signals, then writes context/offer.md and context/icp.md that the other GTM skills read. Run first, once per workspace, before signal or copy work.

    skills/gtm-context/SKILL.md on GitHub (opens in a new tab)
  • headless-gtm-shared

    Reference module for the Headless GTM chain, not a skill to invoke. Holds the record contract every chain skill reads and writes (CONVENTIONS.md) plus the Python helpers they import (common.py, schema.py). Installed alongside the chain so those imports and references resolve; read CONVENTIONS.md when you need the JSONL record shape, the runs/ layout, or the cost-gate rules.

  • prospect-posts

    Scrape recent LinkedIn posts from one or more prospect profiles via Apify and scan them for a theme (e.g. hiring pain, AI-first GTM). Outputs a report with matched excerpts and post links. Use for prospect or account intelligence research before outreach.

    skills/prospect-posts/SKILL.md on GitHub (opens in a new tab)
  • run-first-campaign

    The packaged cold-start campaign workflow - takes an owner with no list, no CRM, and no outbound history from a plain-English business description to an approved campaign sheet in one supervised pass: business context, a proposed source of record (a public directory - registry, professional college, trade association, marketplace, Maps - for local or licensed businesses, or a firmographic pull -…
