@motrix/plugin-cli

Command-line developer tools for authoring, validating, and packaging Motrix plugins.

Ships two bins:

• motrix-plugin — the main developer tool (init/dev/validate/lint/pack)
• create-motrix-plugin — a thin scaffolder invoked via pnpm create motrix-plugin

Install

pnpm add -D @motrix/plugin-cli
# or run without installing:
pnpm dlx @motrix/plugin-cli init my-plugin

Commands

motrix-plugin init <name> [-t basic-resolver|post-action] [-p <publisher>]

Scaffold a new plugin project from a template (basic-resolver or post-action) into ./<name>.

motrix-plugin dev

Watch-build the plugin with esbuild and relaunch a local Motrix install against it (found via $MOTRIX_BIN or a standard Motrix install location).

motrix-plugin validate

Validate motrix-plugin.json against @motrix/plugin-manifest-schema — the same schema the Motrix host uses when installing a plugin. Beyond the schema this also applies the rules a schema cannot express:

• hooks ⇒ hostPermissions — contributing any hook requires at least one hostPermissions entry, or the host refuses to install the plugin
• locale coverage — every %key% the manifest interpolates must exist in en-US, including the ones under contributes.configuration

pack runs this identical gate, so the two commands can never disagree about whether a plugin is shippable.

Schema versioning

validate checks your manifest against the @motrix/plugin-manifest-schema version embedded in the CLI at build time — not whatever copy of the schema your own project has installed. Keep @motrix/plugin-cli up to date so its embedded schema matches the Motrix host you're targeting; schema releases always ship together with a matching CLI release (lockstep), so staying current on the CLI keeps you current on the schema too.

motrix-plugin lint

Static checks on the packed bundle, so run pack first: top-level side-effect detection (guest code must not run effectful code at module scope), a size warning as the bundle approaches the 1 MiB cap, and advisories for invokesCommands entries whose callee may not be installed.

motrix-plugin validate-host-permissions

Reviews hostPermissions in more depth than validate does: each pattern is parsed with the host's own match-pattern grammar, and broad grants (<all_urls>, https://*/*) are reported as warnings so you can narrow them.

motrix-plugin pack

Produce the .moext distributable at dist/<id>-<version>.moext.

Every gate — schema, hooks ⇒ hostPermissions, locale coverage — runs before esbuild writes anything, so a rejected plugin leaves no half-built bundle behind and a .moext the host would refuse to install cannot be created in the first place. The bundle is then checked against the 1 MiB cap and the archive against 5 MiB.

The archive is reproducible: entries are written in sorted order with pinned timestamps and modes, so the same source tree always yields the same bytes, on any machine and in any timezone. pack prints the resulting sha256 — that is the value a registry entry's package.sha256 needs, and re-packing an unchanged tree must reprint it.

Packed → …/dist/acme.demo-1.0.0.moext (4540 bytes)
sha256   5d69eaf3bb44992952beafc67d818ff376b8478de4b32b936ce5e603b963605d

pnpm create motrix-plugin my-plugin [template]

Equivalent to motrix-plugin init, usable without a prior install via the create-* npm convention.
