Description
Slack API integration with managed OAuth. Send messages, manage channels, search conversations, and interact with Slack workspaces. Use this skill when users...
Usage Guidance
Install only if you trust Maton as an API gateway for Slack data. Use the least-privileged Slack connection available, specify the intended connection when multiple workspaces are connected, and require explicit confirmation before posting, deleting, archiving, inviting, kicking, uploading, or removing anything.
Capability Analysis
Type: OpenClaw Skill
Name: slack-api
Version: 1.0.10
The skill provides a standard Slack API integration through the Maton.ai proxy service. It includes well-documented CLI and Python examples for managing Slack messages, channels, and OAuth connections. The documentation in SKILL.md explicitly includes a security instruction requiring user approval for write operations, and no evidence of data exfiltration, malicious execution, or obfuscation was found.
Capability Assessment
Purpose & Capability
The skill clearly presents itself as a Slack API integration for sending messages, managing channels, listing users, searching conversations, files, reactions, and workflow automation; the API reference includes destructive Slack operations, but they are relevant to that integration rather than hidden or unrelated.
Instruction Scope
The skill exposes many Slack read and write operations and explicitly tells the agent to confirm every create, update, or delete action with the user. The approval requirement is documented as an agent instruction rather than enforced code, which is expected for this instruction-only skill but still important for users to follow.
Install Mechanism
There is no executable code in the scanned artifact; installation guidance points to the external Maton CLI via npm or Homebrew, so users must separately trust that CLI source.
Credentials
Network access, a MATON_API_KEY, and Slack OAuth access are proportionate for a Slack API gateway skill, but Slack messages, files, channel identifiers, and API responses may pass through Maton's service.
Persistence & Privilege
Persistent Maton-managed Slack OAuth connections are disclosed, including listing, creating, selecting, and deleting connections. No hidden background process, privilege escalation, or undisclosed persistence is shown.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install slack-api - After installation, invoke the skill by name or use
/slack-api - Provide required inputs per the skill's parameter spec and get structured output
