Lead Gen Tool Builder is an agent skill from explorium-ai/gtm-skills. Lead generation tool builder skill for Claude Code and Codex: scaffolds a complete, self-hostable, ZoomInfo-style B2B lead-generation web app — company & contact search UI, firmographic and technographic filters, CSV list import with match & enrich, CSV export, and one-click push to HubSpot and Salesforce — powered by the Explorium API.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 46 other files, including assets (for example `assets/leadgen-starter/README.md`, `assets/leadgen-starter/package.json` and `assets/leadgen-starter/postcss.config.js`).

It sits in Sales & Support, covering Lead generation, CRM management and Cold outreach. It works with HubSpot and Salesforce. The repository describes itself as: GTM Skills for Claude & Codex. The licence is MIT.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit f0efa6b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Ships script files (JavaScript, from the files we listed), which the agent can run.

No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Lead Gen Tool Builder loads about 1.8k tokens when it runs. Until then it costs about 211 tokens; SKILL.md has 791 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.

Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/lead-gen-tool-builder/SKILL.md (or your agent's skills folder). This skill also uses 42 other files; get the full folder from GitHub.Scaffolds a working, self-hostable lead generation tool: a ZoomInfo-style web app with a left filter rail, a sortable company/contact results table, and a CRM push bar — backed by the Explorium data API, with CSV import/export and field-mapped push to HubSpot and Salesforce.
Unlike the other skills in this repo, which run a prospecting or enrichment
workflow inside your current Claude Code session via the Vibe Prospecting
MCP server, this skill produces a standalone app the user can run, deploy,
and hand to their team — a real lead-gen tool, not a one-off list. Reach for
list-builder or enrich-company when the user wants a prospect list right
now; reach for this skill when they want a tool they can keep using, host,
demo, or white-label.
No personal keys are stored in this skill. The bundled backend reads every
credential from a local .env file at runtime — nothing is hardcoded, so the
generated app is safe to fork, self-host, and share outside your org.
Trigger this for any request to build a lead-gen / prospecting / sales- intelligence app, a company-or-contact search interface, an Explorium-powered app, a self-hosted ZoomInfo/Apollo.io/Clearbit alternative, or a "find leads → enrich → push to CRM" tool that should exist as its own app rather than a single list. Example phrasings: "build me a lead gen tool", "I want something like ZoomInfo but self-hosted", "scaffold a prospecting app with HubSpot push", "give my team a company search tool backed by Explorium".
The bundled template (assets/leadgen-starter/) is a ready-to-run app:
/businesses and /prospects endpoints.cp -R "<this-skill-dir>/assets/leadgen-starter" ./leadgen-app
cd leadgen-appDon't copy node_modules, dist, or .env — the template ships without them.
Only Explorium is required to search; HubSpot/Salesforce are optional and only
needed for CRM push. Summarize from assets/leadgen-starter/README.md:
crm.objects.contacts.write + crm.objects.companies.write scopes.openssl + Connected App steps.cp .env.example .env # paste in the keys from step 2
npm install
npm run dev # API on :4000, web app on :5173Open http://localhost:5173. Search works with just the Explorium key; the
HubSpot/Salesforce push buttons activate once those keys are present.
Run a small company search (e.g. Country = US, Employees = 51-200) and confirm real results load. If CRM keys were provided, select a couple of rows and push to confirm the success modal returns real created-record IDs.
server/ — Node/Express backend; the only place API keys ever live.
explorium.js is the REST client (search, match, bulk-enrich, autocomplete —
note several filter fields have distinct Explorium filter types, e.g.
job_title is any_match_phrase and has_email is exists, handled in
buildFilters). salesforce.js / hubspot.js do CRM auth plus

it never sees a credential. config/filters.ts defines every filter;

Lead generation tool builder skill for Claude Code and Codex: scaffolds a complete, self-hostable, ZoomInfo-style B2B lead-generation web app — company & contact search UI, firmographic and…. Lead Gen Tool Builder is an agent skill from explorium-ai/gtm-skills. Lead generation tool builder skill for Claude Code and Codex: scaffolds a complete, self-hostable, ZoomInfo-style B2B lead-generation web app — company & contact search UI, firmographic and technographic filters, CSV list import with match & enrich, CSV export, and one-click push to HubSpot and Salesforce — powered by the Explorium API.
Lead Gen Tool Builder fits situations like: tasks that involve Lead generation; tasks that involve CRM management; tasks that involve Cold outreach.
Run `npx skills add explorium-ai/gtm-skills --skill lead-gen-tool-builder -a claude-code`. Or copy the skill folder (skills/lead-gen-tool-builder in explorium-ai/gtm-skills) into .claude/skills/lead-gen-tool-builder in your project. Claude Code loads it when a task matches its description.
Run `npx skills add explorium-ai/gtm-skills --skill lead-gen-tool-builder -a codex`. Or copy the skill folder (skills/lead-gen-tool-builder in explorium-ai/gtm-skills) into .agents/skills/lead-gen-tool-builder in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add explorium-ai/gtm-skills --skill lead-gen-tool-builder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lead-gen-tool-builder, .gemini/skills/lead-gen-tool-builder, .github/skills/lead-gen-tool-builder and .opencode/skills/lead-gen-tool-builder in your project.
Going by SKILL.md and its folder, Lead Gen Tool Builder needs JavaScript for the scripts in its folder and the command-line tools its instructions call (npm). Our summary lists: Node.js. Compatibility (from SKILL.md): Requires: Node.js 18+, npm, and an Explorium API key (developers.explorium.ai). HubSpot and Salesforce credentials are optional — only needed to enable CRM push..
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Lead Gen Tool Builder is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.8k tokens (SKILL.md is roughly 7.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
