A saved agent now has a Builtins list: the capabilities its owner gave it (memory.write, profile.write, skills.write, pages.write, dashboard.write, triggers.propose, triggers.run, talkback.channels, talkback.new_channel, files.upload, act.files, act.addons, act.send, act.spend and the opt-in group saved_agents). The list is empty by default, and nothing turns a grant on for a template, an import or a write that omits the field. A chat of the agent holds the grants the user may use at the turn (agent scope). A tool exists when the grant is held, the chat did not switch its group off and the run can hold rights: a sub-agent or a run that started by itself never does. propose_change and revert_change now exist only for a chat that holds the grant of at least one kind, and the schema lists only those kinds. propose_change gains the kinds skill, page and dashboard. A skill is a SKILL.md for the personal or the agent layer, and a skill with locked: true is refused, also as a shadow of a locked personal skill. A page is a set of files checked against the Pages rules and written as one change set. The dashboard is a home.json checked against its schema. All three are re-checked when the owner confirms or edits. GET /api/chats/agents/builtin-grants lists each grant with its title, description and sensitive flag. The agent record, the write body and the export file carry builtins; an old file imports as before and an unknown name is dropped in an import and refused in a write.

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
Context files
capabilities.contextFiles names up to three small index files (one for each scope: user, agent, channel) that the host loads into the prompt of a chat. It needs manifest api 2.
{"contextFiles":[{"scope":"user","path":"Memory/index.md"},{"scope":"agent","path":"Memory/agents/{agent}/index.md","cap":1024}]}
Every path lies under Memory/, ends in .md and holds no parent segment. An agent path holds {agent} once and a channel path holds {channel} once; the host fills them from the chat, never from the model. cap lowers the 2 KiB index cap; it cannot raise it. The add-on declares and the host reads: the add-on gains no access to the files.
