/install trello-api
Description
Trello API integration with managed OAuth. Manage boards, lists, cards, members, and labels. Use this skill when users want to interact with Trello for project management. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login; default to read and list calls, and confirm every write or new connection with the user.
Usage Guidance
Install only if you are comfortable authorizing Maton to broker access to your Trello account. Review write operations carefully before approving them, especially deletes, bulk moves, membership changes, comments, and label or board updates. Prefer OAuth over API keys and revoke unused Trello connections when finished.
Capability Assessment
Credentials
The skill requires shell and network access to call Maton and Trello, which is proportionate for an API integration; the raw HTTP fallback is scoped to situations where the CLI cannot be installed and includes credential-handling cautions.
Install Mechanism
Installation uses the external Maton CLI via npm or Homebrew, with optional SDK packages; this is disclosed and coherent with the integration, but users are trusting the Maton tooling and gateway.
Instruction Scope
The instructions tell the agent to default to read/list calls, verify identifiers first, specify connections when ambiguous, treat API content as untrusted, and obtain explicit user approval before connection creation or any POST, PUT, PATCH, or DELETE operation.
Persistence & Privilege
OAuth tokens or API keys are stored through Maton using the OS credential store and a config profile, which is persistent credential use, but it is clearly disclosed and the skill explicitly forbids reading, printing, exporting, or logging secrets.
Purpose & Capability
The stated purpose is Trello project-management access, and the documented capabilities cover expected Trello resources such as boards, lists, cards, checklists, labels, members, comments, search, and deletes.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install trello-api - After installation, invoke the skill by name or use
/trello-api - Provide required inputs per the skill's parameter spec and get structured output
