Real API integration — not prompt templates.READMELoading documentation…# MachFive Skills [](https://opensource.org/licenses/MIT) [](https://agentskills.io) [](https://machfive.io) Agent Skills that connect any AI coding agent to [MachFive](https://machfive.io) — generate hyper-personalized cold email sequences directly from your AI workflows. Compatible with **Claude Code**, **OpenAI Codex CLI**, **Gemini CLI**, and any tool that supports the [Agent Skills open standard](https://agentskills.io). --- ## What Is This? This repository contains [Agent Skills](https://agentskills.io) that teach your AI agent how to use the MachFive API. Instead of switching between your agent and a separate tool, your agent autonomously calls MachFive to list campaigns, generate personalized email sequences, manage batch jobs, and export results — all through natural conversation. **This is not a prompt template.** It's a live API integration — the agent calls the MachFive platform and returns real generated emails for your actual leads. --- ## Skills | Skill | Triggers | What It Does | |-------|---------|--------------| | [`cold-email`](https://github.com/bluecraft-ai/machfive-skills/blob/HEAD/cold-email/) | Cold email, outreach sequences, lead prospecting, email campaigns | Connects to the MachFive API to generate personalized email sequences for individual leads or batches | --- ## Install ### Claude Code **Via plugin marketplace (recommended):** ``` /plugin marketplace add Bluecraft-AI/machfive-skills /plugin install cold-email@machfive-skills ``` **Manual — personal (all projects):** ```bash git clone https://github.com/Bluecraft-AI/machfive-skills.git cp -r machfive-skills/cold-email/skills/cold-email ~/.claude/skills/ ``` **Manual — project (shared with your team via git):** ```bash cp -r machfive-skills/cold-email/skills/cold-email .claude/skills/ ``` ### OpenAI Codex CLI **Personal:** ```bash git clone https://github.com/Bluecraft-AI/machfive-skills.git cp -r machfive-skills/cold-email/skills/cold-email ~/.agents/skills/ ``` **Project:** ```bash cp -r machfive-skills/cold-email/skills/cold-email .agents/skills/ ``` ### Gemini CLI **Personal:** ```bash git clone https://github.com/Bluecraft-AI/machfive-skills.git cp -r machfive-skills/cold-email/skills/cold-email ~/.gemini/skills/ ``` **Project:** ```bash cp -r machfive-skills/cold-email/skills/cold-email .gemini/skills/ ``` ### Universal (Codex CLI, Gemini CLI, VS Code Copilot, OpenClaw, Kiro, and others) Most agent tools discover skills from a shared cross-platform directory: ```bash git clone https://github.com/Bluecraft-AI/machfive-skills.git cp -r machfive-skills/cold-email/skills/cold-email ~/.agents/skills/ ``` --- ## Prerequisites You need a MachFive API key and at least one campaign set up. **Step 1: Get your API key** 1. Log in at [app.machfive.io](https://app.machfive.io) 2. Go to **Settings → Integrations → API Keys** 3. Click **Create API Key** and copy it **Step 2: Set your environment variable** ```bash export MACHFIVE_API_KEY=your_api_key_here ``` Add it to your shell profile (`.zshrc`, `.bashrc`, etc.) to persist across sessions. **Step 3: Create a campaign** The skill requires a campaign to generate against. Create one at [app.machfive.io/campaigns](https://app.machfive.io/campaigns). If you haven't specified a campaign, the agent will automatically list your available campaigns and ask you to pick one. --- ## What Your Agent Can Do Once installed, the skill activates automatically when you ask about cold email, outreach, or lead sequencing. No slash command needed. **Single lead** ``` Generate a 3-email sequence for jane@acme.com — she's VP of Growth at Acme Corp. Use my SaaS Founders campaign. ``` **Batch** ``` Here are 20 leads [paste list]. Submit them for batch generation using my Marketing Agencies campaign. ``` **Check status** ``` What's the status of my latest batch? ``` **Export** ``` Export my completed batch as CSV. ``` **Browse campaigns** ``` Show me my MachFive campaigns. ``` --- ## How It Works The skill gives your agent full knowledge of the MachFive API: | Endpoint | What the agent uses it for | |----------|---------------------------| | `GET /api/v1/campaigns` | Lists your campaigns so you can pick one | | `POST /api/v1/campaigns/{id}/generate` | Generates a sequence for one lead (sync) | | `POST /api/v1/campaigns/{id}/generate-batch` | Submits multiple leads for async processing | | `GET /api/v1/lists` | Browses your lead lists and batch jobs | | `GET /api/v1/lists/{id}` | Polls batch status until complete | | `GET /api/v1/lists/{id}/export` | Downloads results as CSV or JSON | The agent handles the full workflow autonomously, including polling for batch completion. --- ## MachFive MCP Server If you prefer MCP (Model Context Protocol) over Agent Skills, MachFive also has a dedicated MCP server that provides the same capabilities as structured tools: 👉 [github.com/Bluecraft-AI/machfive-mcp](https://github.com/Bluecraft-AI/machfive-mcp) The MCP server works with Claude Desktop, Cursor, n8n, and any MCP-compatible client. --- ## Repository Structure ``` machfive-skills/ ├── .claude-plugin/ │ └── marketplace.json ← Claude Code marketplace catalog ├── cold-email/ ← Claude Code plugin │ ├── .claude-plugin/ │ │ └── plugin.json ← plugin identity & metadata │ └── skills/ │ └── cold-email/ │ └── SKILL.md ← agent instructions (all platforms) ├── LICENSE └── README.md ``` The `skills/cold-email/SKILL.md` file is the cross-platform skill that works with Claude Code, Codex CLI, Gemini CLI, and any Agent Skills-compatible tool. The `.claude-plugin/` directories are Claude Code-specific metadata for the plugin marketplace. --- ## Pricing MachFive uses a credit-based model (1 credit = 1 lead processed): | Plan | Credits/Month | |------|--------------| | Free | 100 | | Starter | 2,000 | | Growth | 5,000 | | Enterprise | Custom | The skill itself is free. Credits are consumed by the MachFive platform when generating emails. --- ## License MIT — see [LICENSE](https://github.com/bluecraft-ai/machfive-skills/blob/HEAD/LICENSE) for details. --- ## About MachFive [MachFive](https://machfive.io) is an AI-powered cold email generation platform.
