Every plugin exports a default entry object. The SDK provides three helpers for
creating them.
For installed plugins, package.json should point runtime loading at built
JavaScript when available:
{
"fluffbuzz": {
"extensions": ["./src/index.ts"],
"runtimeExtensions": ["./dist/index.js"],
"setupEntry": "./src/setup-entry.ts",
"runtimeSetupEntry": "./dist/setup-entry.js"
}
}
extensions and setupEntry remain valid source entries for workspace and git
checkout development. runtimeExtensions and runtimeSetupEntry are preferred
when FluffBuzz loads an installed package and let npm packages avoid runtime
TypeScript compilation. If an installed package only declares a TypeScript
source entry, FluffBuzz will use a matching built dist/*.js peer when one
exists, then fall back to the TypeScript source.
All entry paths must stay inside the plugin package directory. Runtime entries
and inferred built JavaScript peers do not make an escaping extensions or
setupEntry source path valid.
definePluginEntry
Import: fluffbuzz/plugin-sdk/plugin-entry
For provider plugins, tool plugins, hook plugins, and anything that is not
a messaging channel.
import { definePluginEntry } from "fluffbuzz/plugin-sdk/plugin-entry";
export default definePluginEntry({
id: "my-plugin",
name: "My Plugin",
description: "Short summary",
register(api) {
api.registerProvider({
/* ... */
});
api.registerTool({
/* ... */
});
},
});
| Field | Type | Required | Default |
|---|
id | string | Yes | — |
name | string | Yes | — |
description | string | Yes | — |
kind | string | No | — |
configSchema | FluffBuzzPluginConfigSchema | () => FluffBuzzPluginConfigSchema | No | Empty object schema |
register | (api: FluffBuzzPluginApi) => void | Yes | — |
id must match your fluffbuzz.plugin.json manifest.
kind is for exclusive slots: "memory" or "context-engine".
configSchema can be a function for lazy evaluation.
- FluffBuzz resolves and memoizes that schema on first access, so expensive schema
builders only run once.
defineChannelPluginEntry
Import: fluffbuzz/plugin-sdk/channel-core
Wraps definePluginEntry with channel-specific wiring. Automatically calls
api.registerChannel({ plugin }), exposes an optional root-help CLI metadata
seam, and gates registerFull on registration mode.
import { defineChannelPluginEntry } from "fluffbuzz/plugin-sdk/channel-core";
export default defineChannelPluginEntry({
id: "my-channel",
name: "My Channel",
description: "Short summary",
plugin: myChannelPlugin,
setRuntime: setMyRuntime,
registerCliMetadata(api) {
api.registerCli(/* ... */);
},
registerFull(api) {
api.registerGatewayMethod(/* ... */);
},
});
| Field | Type | Required | Default |
|---|
id | string | Yes | — |
name | string | Yes | — |
description | string | Yes | — |
plugin | ChannelPlugin | Yes | — |
configSchema | FluffBuzzPluginConfigSchema | () => FluffBuzzPluginConfigSchema | No | Empty object schema |
setRuntime | (runtime: PluginRuntime) => void | No | — |
registerCliMetadata | (api: FluffBuzzPluginApi) => void | No | — |
registerFull | (api: FluffBuzzPluginApi) => void | No | — |
setRuntime is called during registration so you can store the runtime reference
(typically via createPluginRuntimeStore). It is skipped during CLI metadata
capture.
registerCliMetadata runs during both api.registrationMode === "cli-metadata"
and api.registrationMode === "full".
Use it as the canonical place for channel-owned CLI descriptors so root help
stays non-activating while normal CLI command registration remains compatible
with full plugin loads.
registerFull only runs when api.registrationMode === "full". It is skipped
during setup-only loading.
- Like
definePluginEntry, configSchema can be a lazy factory and FluffBuzz
memoizes the resolved schema on first access.
- For plugin-owned root CLI commands, prefer
api.registerCli(..., { descriptors: [...] })
when you want the command to stay lazy-loaded without disappearing from the
root CLI parse tree. For channel plugins, prefer registering those descriptors
from registerCliMetadata(...) and keep registerFull(...) focused on runtime-only work.
- If
registerFull(...) also registers gateway RPC methods, keep them on a
plugin-specific prefix. Reserved core admin namespaces (config.*,
exec.approvals.*, wizard.*, update.*) are always coerced to
operator.admin.
defineSetupPluginEntry
Import: fluffbuzz/plugin-sdk/channel-core
For the lightweight setup-entry.ts file. Returns just { plugin } with no
runtime or CLI wiring.
import { defineSetupPluginEntry } from "fluffbuzz/plugin-sdk/channel-core";
export default defineSetupPluginEntry(myChannelPlugin);
FluffBuzz loads this instead of the full entry when a channel is disabled,
unconfigured, or when deferred loading is enabled. See
Setup and Config for when this matters.
In practice, pair defineSetupPluginEntry(...) with the narrow setup helper
families:
fluffbuzz/plugin-sdk/setup-runtime for runtime-safe setup helpers such as
import-safe setup patch adapters, lookup-note output,
promptResolvedAllowFrom, splitSetupEntries, and delegated setup proxies
fluffbuzz/plugin-sdk/channel-setup for optional-install setup surfaces
fluffbuzz/plugin-sdk/setup-tools for setup/install CLI/archive/docs helpers
Keep heavy SDKs, CLI registration, and long-lived runtime services in the full
entry.
Bundled workspace channels that split setup and runtime surfaces can use
defineBundledChannelSetupEntry(...) from
fluffbuzz/plugin-sdk/channel-entry-contract instead. That contract lets the
setup entry keep setup-safe plugin/secrets exports while still exposing a
runtime setter:
import { defineBundledChannelSetupEntry } from "fluffbuzz/plugin-sdk/channel-entry-contract";
export default defineBundledChannelSetupEntry({
importMetaUrl: import.meta.url,
plugin: {
specifier: "./channel-plugin-api.js",
exportName: "myChannelPlugin",
},
runtime: {
specifier: "./runtime-api.js",
exportName: "setMyChannelRuntime",
},
});
Use that bundled contract only when setup flows truly need a lightweight runtime
setter before the full channel entry loads.
Registration mode
api.registrationMode tells your plugin how it was loaded:
| Mode | When | What to register |
|---|
"full" | Normal gateway startup | Everything |
"setup-only" | Disabled/unconfigured channel | Channel registration only |
"setup-runtime" | Setup flow with runtime available | Channel registration plus only the lightweight runtime needed before the full entry loads |
"cli-metadata" | Root help / CLI metadata capture | CLI descriptors only |
defineChannelPluginEntry handles this split automatically. If you use
definePluginEntry directly for a channel, check mode yourself:
register(api) {
if (api.registrationMode === "cli-metadata" || api.registrationMode === "full") {
api.registerCli(/* ... */);
if (api.registrationMode === "cli-metadata") return;
}
api.registerChannel({ plugin: myPlugin });
if (api.registrationMode !== "full") return;
// Heavy runtime-only registrations
api.registerService(/* ... */);
}
Treat "setup-runtime" as the window where setup-only startup surfaces must
exist without re-entering the full bundled channel runtime. Good fits are
channel registration, setup-safe HTTP routes, setup-safe gateway methods, and
delegated setup helpers. Heavy background services, CLI registrars, and
provider/client SDK bootstraps still belong in "full".
For CLI registrars specifically:
- use
descriptors when the registrar owns one or more root commands and you
want FluffBuzz to lazy-load the real CLI module on first invocation
- make sure those descriptors cover every top-level command root exposed by the
registrar
- use
commands alone only for eager compatibility paths
Plugin shapes
FluffBuzz classifies loaded plugins by their registration behavior:
| Shape | Description |
|---|
| plain-capability | One capability type (e.g. provider-only) |
| hybrid-capability | Multiple capability types (e.g. provider + speech) |
| hook-only | Only hooks, no capabilities |
| non-capability | Tools/commands/services but no capabilities |
