ProtonMail

**Quick judgment** A focused, technically oriented skill that gives agents read/search access to ProtonMail through an IMAP bridge plus an optional daily "important mail" scan. Well-suited for power users comfortable with Docker or Go-based services, less so for non-technical setups. **What it does well** - Bridges ProtonMail into standard IMAP-based workflows using either Proton Bridge (recommended) or hydroxide (headless). - Supports core read-only operations: list mailboxes, show recent inbox, unread-only view, keyword search, and reading individual emails. - Provides a daily scanning script that flags important emails via configurable sender and keyword patterns (DE/EN/NL), and suggests Sieve rules to pre-sort newsletters and highlight important messages. **Risks & limitations** - **Privacy/security:** Any agent using this skill gains programmatic access to the contents and metadata of your ProtonMail mailbox. This can expose sensitive personal or business information to the agent environment and, depending on how you configure your system, to external LLM services. - **Third-party components:** Relies on external projects (Docker image for Proton Bridge; hydroxide) that must be trusted and maintained. Misconfiguration or outdated components can introduce security or reliability issues. - **Setup complexity:** Requires either Docker-based Proton Bridge initialization or compiling/running hydroxide, plus manual configuration of host, port, user, and bridge password. Non-technical users may find this setup challenging. - **Misclassification risk:** The "important email" detection is heuristic and pattern-based; it can miss genuinely urgent messages or flag non-critical ones, especially outside the DE/EN/NL language scope unless reconfigured. **Recommended scenarios** - You are a technically comfortable ProtonMail user who wants your AI/agent to **read, search, and triage** your emails but you do not need sending or mailbox mutation (move/delete) features. - You want a **daily digest of important messages** (e.g., from banks, government, schools) and are willing to tune sender/keyword patterns and/or Sieve rules. - You already run or are willing to run **Proton Bridge or hydroxide** on a machine where your OpenClaw agent can connect via localhost IMAP. - You accept the privacy/security implications of giving an automated system read access to your ProtonMail account and have appropriate safeguards in place (restricted prompts, access controls, network isolation, etc.).
