What This Skill Does

The PostWall skill serves as a robust security and oversight layer between your AI agents and your email infrastructure. By enforcing a human-in-the-loop requirement, it ensures that your AI agent does not autonomously send or read sensitive email data without your explicit approval. It facilitates a secure workflow where the agent polls for approved emails and submits draft communications to a centralized dashboard. This is essential for maintaining control over automated outreach and managing incoming communication in professional environments.

Installation

To integrate this skill into your workflow, you must use the following command in your terminal:

clawhub install openclaw/skills/skills/casperaiassist/postwall

Once installed, finalize the configuration by authenticating your account with your unique API key obtained from the PostWall dashboard:

postwall auth pw_your_api_key_here

Use Cases

  • Automated Client Support: Draft responses to customer inquiries that require human verification before being sent out.
  • Secure Inbox Management: Allow your AI to triage and summarize non-sensitive emails while keeping private or critical communications behind a manual approval gateway.
  • Batch Communication Processing: Use the mark-read functionality to clean up your inbox after the agent has successfully ingested metadata or processed routine notifications.
  • Compliance-Heavy Workflows: Ensure that every outgoing email generated by an AI assistant is logged and reviewed for policy adherence.

Example Prompts

  1. "Check for new emails and give me a summary of the ones marked as approved."
  2. "Draft an email to [email protected] apologizing for the delay and mention that a manager will reach out shortly."
  3. "List all my pending emails and mark the processed ones as read to clear my workspace."

Tips & Limitations

  • Proactive Polling: Use the postwall check command in your agent's loop to trigger notifications only when new, approved content arrives, saving computational resources.
  • Approval Lifecycle: Remember that drafts submitted via postwall draft remain in a 'pending' state indefinitely until manually approved in the PostWall dashboard. Ensure you monitor the provided approveUrl.
  • Scope: This skill only interacts with emails routed through the PostWall gateway; it does not replace your primary email client but acts as a secure middleware.
  • Security: Always treat your PostWall API key as a sensitive credential. Do not hardcode it in shared repositories.
