Description
Postmark integration. Manage Emails, Templates, Servers, Signatures, Domains, MessageStreams. Use when the user wants to interact with Postmark data.
Usage Guidance
This skill is coherent: it uses the Membrane CLI to talk to Postmark rather than asking you for API keys. Before installing or using it: (1) verify you trust Membrane (https://getmembrane.com) because the platform will hold your Postmark credentials and act on your behalf; (2) inspect the npm package @membranehq/cli (publisher, package page, repository) before running a global npm install, since global installs modify system paths; (3) be prepared to complete an interactive or headless OAuth-style login flow (you may need to paste a code or open a browser); and (4) if you need stricter control over credentials, consider creating limited-scope Postmark API keys and reviewing Membrane's privacy/security docs. Overall this appears internally consistent and proportional to its stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: postmark
Version: 1.0.3
The skill bundle provides instructions for an AI agent to integrate with Postmark via the Membrane CLI. It guides the agent through installation (npm install -g @membranehq/cli), authentication, and resource management (emails, templates, etc.). The instructions are consistent with the stated purpose and encourage security best practices, such as delegating credential management to the Membrane platform rather than handling raw API keys.
Capability Assessment
Purpose & Capability
The name/description say this is a Postmark integration and the SKILL.md consistently instructs use of the Membrane CLI to connect to Postmark (connect, action list, run actions). Required capabilities (network + Membrane account) match the stated purpose.
Instruction Scope
Instructions focus on installing the Membrane CLI, performing Membrane login, creating a Postmark connection, discovering and running actions. They do not instruct the agent to read arbitrary local files, request other environment variables, or exfiltrate data to unexpected endpoints. Headless login flow and action polling are described explicitly.
Install Mechanism
There is no registry install spec, but SKILL.md tells users to run `npm install -g @membranehq/cli@latest`. Installing a global npm package is a standard but privileged operation (writes to system paths); you should verify the package and publisher before installing.
Credentials
The skill declares no required environment variables or secrets and explicitly advises not to ask users for Postmark API keys (Membrane manages auth). The level of credential access described is proportional, but trusting Membrane implies delegating Postmark access to that third party.
Persistence & Privilege
The skill is not always-enabled, is user-invocable, and does not request persistent system-wide configuration changes. It does not attempt to modify other skills or require elevated privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install postmark - After installation, invoke the skill by name or use
/postmark - Provide required inputs per the skill's parameter spec and get structured output
