Modernisation Engine

Controlled migration engine: maps an existing codebase, turns the behaviour that must survive into reviewable contracts, prepares a separate candidate and records old/new evidence before any production change.

Good to know before installing

27 tools plus a `hermes modernise` CLI and `/modernise` slash command; `assess`, `plan`, `record` and `recipe` read source trees and files at absolute paths the agent supplies (refusing symlinks, `.env`, `auth.json`, `credentials.json` and SSH keys) and never import or run repository code; `recipe` creates a new directory at an agent-chosen absolute path holding a copy of the source with fixed metadata edits; job records live under the plugin's data directory; only after you set `operator_config` and sign a one-use Ed25519 owner grant do `run`, `cancel` and `recover` invoke the local `docker` CLI, outside Hermes's command-approval prompt, to run, inspect and remove rootless, network-disabled, read-only, resource-limited containers from digest-pinned images you allow-list (never pulled); no network calls, no telemetry, no self-updater.

From the plugin's catalog listing.

How to install

  1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
    hermes plugins install modernisation-engine
  2. Said no? Turn it on later:
    hermes plugins enable modernisation-engine
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
