A connector kind can now declare the roles it gives to a sender and the capabilities it can grant to a role. The owner of a binding enables a ceiling of capabilities and maps roles to them. The host stores these values and returns them with the binding and the kind list, so an add-on settings page can show them. Capability names are a closed list owned by the host. Sensitive names may be listed by a kind but are never granted to a role; only a paired sender can use them. Pairing proves that the owner controls a platform account. The owner asks for a one-use code (valid ten minutes) and sends it as a direct message to the bot from an allowlisted account. The host checks the code before any model turn and never logs it. A binding holds three paired senders, a pairing ends after 90 days, and five wrong codes in an hour lock the sender out for an hour. Contract: connector kinds gain optional roles and permissions, and a message gains optional roles. They need manifest api 2, which the host already accepts; protocol is unchanged and manifests that declare nothing new behave as before. The host drops roles a kind does not declare. Enforcement of the capabilities by feature is not part of this change. Assisted-by: Claude:claude-sonnet-5-5 go swag
Typed addon contract
ParseManifest is the strict v1 parser used by staging and package verification.
Unknown fields, duplicate keys, invalid declarations, and unsupported compatibility ranges fail validation.
The typed declarations remain additive strict v1 fields, not a new protocol version.
capabilities.ui.homeCommandsnames installed pages, never tools or install actions.capabilities.executionProvidernames execution tools and one declared UI-only read status tool.capabilities.hostOperations.requiredand.optionalrequest exact operation names, never grants.capabilities.networkdeclares the egress policy of the commands an add-on runs (kindegress-check, a title, preset titles). It attaches thenetwork-policyhost control and needs manifest api 2.
ValidHostOp validates syntax only. The host's registered vocabulary determines support.
Administrator policy and request admission remain authoritative, including for optional operations.
Status is advisory; an isolation report does not prove network enforcement or authorize execution.
See the addon guide for JSON examples, bounds, collision rules, lifecycle behavior, policy migration, and old-host staging refusal. Old hosts must retain the old package when an extension-bearing upgrade is refused. Release maintainers select the minimum supporting release and the duration of any legacy package support.
Typed owner observations currently support local-owner JSON selections only. Named-user and SQL selections remain unavailable and fail closed; they are not completed scope.
Optional model actions
capabilities.ui.modelActions maps a model capability to a declared page:
{"modelActions":[{"capability":"FLAG_IMAGE","page":"studio","path":"images"}]}
capability and page are required. path is an optional nonempty relative
suffix. There is one mapping per capability per addon, at most 27 mappings.
The SDK route bounds apply to page/path: 256 ASCII characters, eight segments,
and 1–64 characters per segment from [A-Za-z0-9._~-], excluding . and ...
Absolute paths, URLs, queries, fragments, percent encoding and backslashes fail.
Unknown, duplicate and noncanonical keys fail strict parsing.
The exact vocabulary is ModelActionCapabilities(): all concrete flags in
config.GetAllModelConfigUsecases() except native FLAG_CHAT and
FLAG_COMPLETION and aggregate FLAG_LLM. FLAG_ANY is not a concrete flag.
A core/config parity test guards this list without importing core into contract.
Declarations carry no priorities, labels, permissions or model query templates.
Apps exposes a cloned typed list only through its existing installed UI view;
unavailable UI omission is unchanged. Protocol registration uses the same
contract.Capabilities, and verifies exact equality including these actions.
Studio owns image/video/TTS/sound destinations; Talk owns transcription at its existing landing page; Face and Voice own face/speaker recognition respectively. Talk does not currently consume a selected-model query value. Its pipeline and landing semantics remain unchanged. Frontend dispatch and route cleanup are a separate milestone; this contract alone does not change model Open behavior.
The allowed capability strings are:
FLAG_EDIT FLAG_EMBEDDINGS FLAG_RERANK FLAG_IMAGE FLAG_TRANSCRIPT FLAG_TTS
FLAG_SOUND_GENERATION FLAG_TOKENIZE FLAG_VAD FLAG_VIDEO FLAG_DETECTION
FLAG_VISION FLAG_FACE_RECOGNITION FLAG_SPEAKER_RECOGNITION FLAG_AUDIO_TRANSFORM
FLAG_DIARIZATION FLAG_SOUND_CLASSIFICATION FLAG_REALTIME_AUDIO FLAG_SCORE
FLAG_DEPTH FLAG_TOKEN_CLASSIFY FLAG_3D FLAG_3D_ANIMATION FLAG_DECISIONS
FLAG_UPSCALE FLAG_MOTION FLAG_FORECAST
