gmailGmail API integration with managed OAuth. An agent skill from CraftOS-dev/CraftBot.
Gmail is an agent skill from CraftOS-dev/CraftBot. Gmail API integration with managed OAuth. Read, send, and manage emails, threads, labels, and drafts. Use this skill when users want to interact with Gmail. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `.clawhub/origin.json` and `_meta.json`). Compatibility notes: Requires network access and valid Maton API key
It sits in Backend & APIs, covering Email management and Microservices. It works with Gmail. The repository describes itself as: One agent. Every kind of work. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b50970c. 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.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pythoncurlFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
gateway.maton.aictrl.maton.aiconnect.maton.aiAlso links to:
developers.google.commaton.aidiscord.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
MATON_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires network access and valid Maton API key
From compatibility in the SKILL.md frontmatter.
Gmail loads about 2.2k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 375 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 found no risky patterns in SKILL.md.
Automated static check — not a guarantee. 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.

Gmail API integration with managed OAuth. An agent skill from CraftOS-dev/CraftBot. Gmail is an agent skill from CraftOS-dev/CraftBot. Gmail API integration with managed OAuth.
Gmail fits situations like: users want to interact with Gmail; tasks that involve Email management; tasks that involve Microservices.
Run `npx skills add CraftOS-dev/CraftBot --skill gmail -a claude-code`. Or copy the skill folder (skills/gmail in CraftOS-dev/CraftBot) into .claude/skills/gmail in your project. Claude Code loads it when a task matches its description.
Run `npx skills add CraftOS-dev/CraftBot --skill gmail -a codex`. Or copy the skill folder (skills/gmail in CraftOS-dev/CraftBot) into .agents/skills/gmail 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 CraftOS-dev/CraftBot --skill gmail -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gmail, .gemini/skills/gmail, .github/skills/gmail and .opencode/skills/gmail in your project.
Going by SKILL.md and its folder, Gmail needs the command-line tools its instructions call (python and curl) and credentials named MATON_API_KEY. Our summary lists: Python 3; A credential in MATON_API_KEY; A credential in YOUR_API_KEY. Compatibility (from SKILL.md): Requires network access and valid Maton API key.
SKILL.md names 6 domains. In commands or code: gateway.maton.ai, ctrl.maton.ai and connect.maton.ai; the agent is likely to contact these when it follows the instructions. As links in the text: developers.google.com, maton.ai and discord.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Gmail is published under the MIT licence (from the LICENSE file in the skill folder). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Gmail: Smtp Email Sender (openakita/openakita, 2k stars), Google Workspace (RedWoodOG/Hermes-Desktop, 177 stars), Deliverability Test Public (growthenginenowoslawski/coldoutboundskills, 742 stars) and Google Loops (garrytan/gbrain, 31k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
