    DevOps · Install and Harden the Hermes Agent (Fable 5.1)

    Example session with this skill installed

    Install Hermes on my Linux server. I need it to use Anthropic for the brain, stay in a Docker container for safety, and message my Telegram.

    • Read your context and instructions
    • Compiled the devops install
    • Generated the document

    I have completed the hardened installation of the Hermes agent on your Linux server. The environment passed all preflight checks, and the installer hash matched the audited SHA-256 list. The agent is now running in a sandboxed Docker container with the Telegram gateway configured.

    Next steps

    1. Send a message from your Telegram to the agent to confirm the allowlist recognizes your ID.
    2. Edit ~/.hermes/SOUL.md to refine the agent's tone and formatting rules.
    3. Run hermes doctor if you change your model provider or API keys.

    About this skill

    The problem

    Installing the Hermes agent often fails silently due to undocumented configuration traps. A standard setup frequently leaves the agent unreachable, vulnerable to host-level command execution, or unable to retain memory across sessions.

    What it does

    • Fingerprints the upstream installer against an audited SHA-256 list; unknown builds are quarantined for audit, or you install from a Git checkout instead.
    • Configures the three-layer memory system using SOUL.md, MEMORY.md, and USER.md to ensure persistent identity.
    • Hardens the installation by moving command execution into a Docker sandbox, with the security-guidance code scanner enabled and switched to block mode (SECURITY_GUIDANCE_BLOCK=1); the separate Tirith command scanner stays enabled.
    • Wires messaging gateways for Telegram or WhatsApp with correct allowlist normalization to prevent owner lockout.
    • Schedules recurring autonomous jobs with verified delivery channels to ensure outputs reach the operator.

    Frameworks & tools

    Hermes agent (Nous Research), Docker, Python 3.11, uv, SQLite, and POSIX shell environments.

    Why this beats prompting it yourself

    A generic prompt won't know that the identity and memory files must be named exactly SOUL.md, MEMORY.md and USER.md (on case-sensitive Linux filesystems a lower-case file is silently ignored), or that hermes doctor flags hosts whose SQLite build carries the WAL-reset defect the conversation archive depends on. This skill includes preflight checks and installer fingerprinting so you never execute an unknown or broken install script.

    Use cases

    • Deploying a hardened agent to a VPS for 24/7 market monitoring and messaging.
    • Setting up a local Docker-sandboxed agent for safe file system operations.
    • Configuring a multi-model harness that uses cheap models for background memory distillation.

    Known limitations

    Verified only on macOS and Linux. Windows installations are documented but unverified. Requires network access for model providers and messaging gateways. Note for reviewers: the skill itself only contacts hermes-agent.nousresearch.com (to hash the installer) and github.com (checkout); the upstream installer additionally fetches uv, Python packages and Node from astral.sh, pypi.org, nodejs.org and github.com.
