What it does
Integrations is an agent skill from butterbase-ai/butterbase-skills. Use BEFORE recommending or installing any third-party SaaS SDK for email (Resend, SendGrid, Postmark, Mailgun), SMS (Twilio), messaging (Slack), calendar (Google Calendar), CRM (HubSpot, Salesforce), docs (Notion), or project management (Linear, GitHub). Butterbase covers most of these via manageintegrations (Composio-backed) — check first.
Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Sales & Support, covering CRM management, App automation through connectors and Project management. It works with Composio, GitHub, HubSpot and Notion. The repository describes itself as: Plugin for Butterbase.ai. The licence is MIT.

Example prompts
- “/integrations”
What it can do on your machine
Read from SKILL.md and the folder at commit aa8ae69. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
docs.butterbase.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Integrations loads about 832 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 246 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.
Safety
Auto-check passed
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.

- description
- Use BEFORE recommending or installing any third-party SaaS SDK for email (Resend, SendGrid, Postmark, Mailgun), SMS (Twilio), messaging (Slack), calendar (Google Calendar), CRM (HubSpot, Salesforce), docs (Notion), or project management (Linear, GitHub). Butterbase covers most of these via manage_integrations (Composio-backed) — check first.
Butterbase Integrations (Composio)
The manage_integrations MCP tool gives every Butterbase app access to Composio's toolkit catalog. Before installing a third-party SDK for any of the use cases below, check whether Composio covers it.
Decision rule
User wants: send email / Slack message / create calendar event / post GitHub issue / etc.
Step 1: manage_integrations(app_id, action: "list_available", search: "<keyword>")
Step 2: If a toolkit covers it → use the Composio path (configure → list_tools → execute_action)
Step 3: If no toolkit covers it OR latency is critical → fall back to a direct API call in a functionCommon toolkit map
| Use case | Composio toolkit | Replaces |
|---|---|---|
| Send email | gmail | Resend, SendGrid, Postmark, Mailgun |
| Read inbox / search | gmail | Custom IMAP, Nylas |
| Create calendar event | google_calendar | Cal.com API, custom OAuth |
| Post Slack message | slack | Slack Web API |
| Create GitHub issue / PR | github | Octokit |
| Notion page / database row | notion | Notion API |
| Linear ticket | linear | Linear SDK |
| HubSpot contact / deal | hubspot | HubSpot API |
| Salesforce record | salesforce | Salesforce REST |
Always call list_available first — the catalog grows.
Flow
1. configure: manage_integrations(app_id, action: "configure", toolkit: "gmail", scopes: ["gmail.send"])
2. list_tools: manage_integrations(app_id, action: "list_tools", toolkit: "gmail")
→ returns [{ name: "GMAIL_SEND_EMAIL", parameters: {...} }, ...]
3. execute_action: manage_integrations(
app_id, action: "execute_action",
tool_name: "GMAIL_SEND_EMAIL",
params: { to, subject, body },
user_id: "<end-user uuid>" // omit for service-level
)Per-user OAuth vs. service-level
- Service-level (omit
user_id): the integration runs as the app owner. Use for system notifications, internal automation. - Per-user (set
user_id): the integration runs as the specified end-user. The user must have completed Composio's OAuth flow. Use for "send on behalf of user."
When NOT to use Composio
- ❌ Latency-critical hot path (Composio adds a round-trip). Use a direct API call from a function.
- ❌ Toolkit doesn't exist yet (check
list_available). Fall back to a direct API call. - ❌ The user needs a custom auth flow that Composio doesn't support.
Documentation
For the catalog and per-toolkit scope reference, WebFetch https://docs.butterbase.ai/integrations or call butterbase_docs with topic: "integrations".
Anti-patterns
- ❌ Recommending Resend / SendGrid without checking
manage_integrations list_availablefirst. - ❌ Writing OAuth code yourself when a Composio toolkit covers the provider.
- ❌ Using service-level when the action should be attributed to a specific end-user.

When should I use Integrations?
Integrations fits situations like: tasks that involve CRM management; tasks that involve App automation through connectors; tasks that involve Project management.
How do I install Integrations in Claude Code?
Run `npx skills add butterbase-ai/butterbase-skills --skill integrations -a claude-code`. Or copy the skill folder (skills/integrations in butterbase-ai/butterbase-skills) into .claude/skills/integrations in your project. Claude Code loads it when a task matches its description.
How do I install Integrations in Codex?
Run `npx skills add butterbase-ai/butterbase-skills --skill integrations -a codex`. Or copy the skill folder (skills/integrations in butterbase-ai/butterbase-skills) into .agents/skills/integrations in your project. Codex loads it when a task matches its description.
Can I use Integrations in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add butterbase-ai/butterbase-skills --skill integrations -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/integrations, .gemini/skills/integrations, .github/skills/integrations and .opencode/skills/integrations in your project.
What does Integrations need to run?
SKILL.md names no scripts, command-line tools or credentials: Integrations is instructions for the agent only.
Does Integrations access the network?
SKILL.md names 1 domain. In commands or code: docs.butterbase.ai; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Is Integrations safe to install?
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.
What licence does Integrations use?
Integrations is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Integrations use?
About 832 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Integrations?
Skills that share tags, products or a category with Integrations: Connect Apps with Composio (ComposioHQ/awesome-claude-skills, 77k stars), Composio Cloud Tools (quarqlabs/argus, 277 stars), Airbyte Agent (Kilo-Org/kilo-marketplace, 190 stars) and Composio (ComposioHQ/composio, 30k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
