Plugin Setup and Config
Reference for plugin packaging (package.json metadata), manifests
(velaclaw.plugin.json), setup entries, and config schemas.
Package metadata
Yourpackage.json needs an velaclaw field that tells the plugin system what
your plugin provides:
Channel plugin:
velaclaw-clawhub-package.json
compat and build
fields are required. The canonical publish snippets live in
docs/snippets/plugin-publish/.
velaclaw fields
velaclaw.channel
velaclaw.channel is cheap package metadata for channel discovery and setup
surfaces before runtime loads.
Example:
exposure supports:
configured: include the channel in configured/status-style listing surfacessetup: include the channel in interactive setup/configure pickersdocs: mark the channel as public-facing in docs/navigation surfaces
showConfigured and showInSetup remain supported as legacy aliases. Prefer
exposure.
velaclaw.install
velaclaw.install is package metadata, not manifest metadata.
If
minHostVersion is set, install and manifest-registry loading both enforce
it. Older hosts skip the plugin; invalid version strings are rejected.
allowInvalidConfigRecovery is not a general bypass for broken configs. It is
for narrow bundled-plugin recovery only, so reinstall/setup can repair known
upgrade leftovers like a missing bundled plugin path or stale channels.<id>
entry for that same plugin. If config is broken for unrelated reasons, install
still fails closed and tells the operator to run velaclaw doctor --fix.
Deferred full load
Channel plugins can opt into deferred loading with:setupEntry during the pre-listen startup
phase, even for already-configured channels. The full entry loads after the
gateway starts listening.
If your setup/full entry registers gateway RPC methods, keep them on a
plugin-specific prefix. Reserved core admin namespaces (config.*,
exec.approvals.*, wizard.*, update.*) stay core-owned and always resolve
to operator.admin.
Plugin manifest
Every native plugin must ship anvelaclaw.plugin.json in the package root.
Velaclaw uses this to validate config without executing plugin code.

ClawHub publishing
For plugin packages, use the package-specific ClawHub command:clawhub package publish.
Setup entry
Thesetup-entry.ts file is a lightweight alternative to index.ts that
Velaclaw loads when it only needs setup surfaces (onboarding, config repair,
disabled channel inspection).
defineBundledChannelSetupEntry(...) from
velaclaw/plugin-sdk/channel-entry-contract instead of
defineSetupPluginEntry(...). That bundled contract also supports an optional
runtime export so setup-time runtime wiring can stay lightweight and explicit.
When Velaclaw uses setupEntry instead of the full entry:
- The channel is disabled but needs setup/onboarding surfaces
- The channel is enabled but unconfigured
- Deferred loading is enabled (
deferConfiguredChannelFullLoadUntilAfterListen)
setupEntry must register:
- The channel plugin object (via
defineSetupPluginEntry) - Any HTTP routes required before gateway listen
- Any gateway methods needed during startup
config.* or update.*.
What setupEntry should NOT include:
- CLI registrations
- Background services
- Heavy runtime imports (crypto, SDKs)
- Gateway methods only needed after startup
Narrow setup helper imports
For hot setup-only paths, prefer the narrow setup helper seams over the broaderplugin-sdk/setup umbrella when you only need part of the setup surface:
Use the broader
plugin-sdk/setup seam when you want the full shared setup
toolbox, including config-patch helpers such as
moveSingleAccountChannelSectionToDefaultAccount(...).
The setup patch adapters stay hot-path safe on import. Their bundled
single-account promotion contract-surface lookup is lazy, so importing
plugin-sdk/setup-runtime does not eagerly load bundled contract-surface
discovery before the adapter is actually used.
Channel-owned single-account promotion
When a channel upgrades from a single-account top-level config tochannels.<id>.accounts.*, the default shared behavior is to move promoted
account-scoped values into accounts.default.
Bundled channels can narrow or override that promotion through their setup
contract surface:
singleAccountKeysToMove: extra top-level keys that should move into the promoted accountnamedAccountPromotionKeys: when named accounts already exist, only these keys move into the promoted account; shared policy/delivery keys stay at the channel rootresolveSingleAccountPromotionTarget(...): choose which existing account receives promoted values
defaultAccount points at an existing non-canonical key
such as Ops, promotion preserves that account instead of creating a new
accounts.default entry.
Config schema
Plugin config is validated against the JSON Schema in your manifest. Users configure plugins via:api.pluginConfig during registration.
For channel-specific config, use the channel config section instead:
Building channel config schemas
UsebuildChannelConfigSchema from velaclaw/plugin-sdk/core to convert a
Zod schema into the ChannelConfigSchema wrapper that Velaclaw validates:
Setup wizards
Channel plugins can provide interactive setup wizards forvelaclaw onboard.
The wizard is a ChannelSetupWizard object on the ChannelPlugin:
ChannelSetupWizard type supports credentials, textInputs,
dmPolicy, allowFrom, groupAccess, prepare, finalize, and more.
See bundled plugin packages (for example the Discord plugin src/channel.setup.ts) for
full examples.
For DM allowlist prompts that only need the standard
note -> prompt -> parse -> merge -> patch flow, prefer the shared setup
helpers from velaclaw/plugin-sdk/setup: createPromptParsedAllowFromForAccount(...),
createTopLevelChannelParsedAllowFromPrompt(...), and
createNestedChannelParsedAllowFromPrompt(...).
For channel setup status blocks that only vary by labels, scores, and optional
extra lines, prefer createStandardChannelSetupStatus(...) from
velaclaw/plugin-sdk/setup instead of hand-rolling the same status object in
each plugin.
For optional setup surfaces that should only appear in certain contexts, use
createOptionalChannelSetupSurface from velaclaw/plugin-sdk/channel-setup:
plugin-sdk/channel-setup also exposes the lower-level
createOptionalChannelSetupAdapter(...) and
createOptionalChannelSetupWizard(...) builders when you only need one half of
that optional-install surface.
The generated optional adapter/wizard fail closed on real config writes. They
reuse one install-required message across validateInput,
applyAccountConfig, and finalize, and append a docs link when docsPath is
set.
For binary-backed setup UIs, prefer the shared delegated helpers instead of
copying the same binary/status glue into every channel:
createDetectedBinaryStatus(...)for status blocks that vary only by labels, hints, scores, and binary detectioncreateCliPathTextInput(...)for path-backed text inputscreateDelegatedSetupWizardStatusResolvers(...),createDelegatedPrepare(...),createDelegatedFinalize(...), andcreateDelegatedResolveConfigured(...)whensetupEntryneeds to forward to a heavier full wizard lazilycreateDelegatedTextInputShouldPrompt(...)whensetupEntryonly needs to delegate atextInputs[*].shouldPromptdecision
Publishing and installing
External plugins: publish to ClawHub or npm, then install:npm: override. Use the normal npm package spec when you
want the npm path after ClawHub fallback:
For npm-sourced installs,
velaclaw plugins install runs
npm install --ignore-scripts (no lifecycle scripts). Keep plugin dependency
trees pure JS/TS and avoid packages that require postinstall builds.Related
