hermes-plugin-development — Design, register, and debug Hermes plugins — hooks, YAML wiring, profile detection, token routing patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hermes Plugin Development Use when: creating, debugging, or integrating Hermes Agent plugins, including Python backend plugins (tools, hooks, routers, middleware) and JavaScript Hermes Desktop runtime plugins. ## Core patterns - Choose the extension surface first: - Backend plugins live under `~/.hermes/plugins/<name>/` and add tools, hooks, commands, providers, or middleware. - Desktop runtime plugins live under `$HERMES_HOME/desktop-plugins/<name>/plugin.js` and add native UI contributions through `@hermes/plugin-sdk`. For model-picker specifics, including a Desktop-local `/switch` command plus backend command-inventory bridge, use `references/desktop-model-picker-plugin.md`. - Resolve the requested interaction surface before building anything. “TUI,” “terminal,” “over SSH,” or “from Windows over SSH” means the prompt_toolkit CLI, not Hermes Desktop. Never substitute a Desktop popover or a backend text-response command. …

How to install
mdr add atlasomnia/hermes-custom-pack/hermes-plugin-development@sha256:d2c6c397994e53f0The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
