Editorial Apply

editorial_apply

Commit an integrated editorial edit to the saved project composition with both runExpectedRevision and guarded composition fields. Preserve the observed concurrency basis and the composition journal identity: nested composition.commandId must equal composition.clientId + ":" + composition.sequence. The session call commandId is a separate HTTP request identity.

Input Schema

-  "description": "Author a scene shot and place it on a dedicated overlay track. The host validates the scene, generates and registers an immutable wrapper component source, and emits the ordinary track/clip operations carrying `props.componentRef` — you edit a scene SPEC, never wrapper TSX or a source hash. Registration and the composition update are ONE undoable edit; a failure publishes nothing and leaves no clip pointing at an unresolved source. REQUIRED: `clipId`, `startTime`, `duration`, `scene` and `assets` (send `{}` when no layer references a slot), plus EXACTLY ONE of `trackId` (an existing dedicated scene track) or `newTrack: true` (mint one). A minted scene track is appended at the BACK like every new track, so it paints under existing tracks; raise it with `reorderTracks` (index 0 is the top layer). That track holds scene-shot clips and gaps only — no generic component/primitive/media clips in v1 — and existing generic overlay tracks are unaffected. Scene clips use front zPlane and full-frame placement: outer per-clip `region`, `position`, `scale`, `rotation`, `fit`, `effects`, keyframes (`tweens`/`automation`), `params.transition`, `params.sequenceGroup` and internal fadeIn/fadeOut are REFUSED with a path, because the shot's own layer transforms are the single transform owner. TEXT: `space: \"screen\"` text is composed above the world result, stays fixed in the frame and stays sharp through focus; `space: \"world\"` text is rasterized into the 3D scene, moves with the camera and is occluded by geometry. Screenshots and world text are UNLIT and colour-managed so product UI colours are not tinted by the studio lighting, while device bodies are lit and cast shadows; an unlit surface still occludes. SCOPE GAP (pre-existing, neither closed nor changed by scene shots): global wrap effects — composition-level grades and camera effects — do not reach front-overlay clips, so they do not affect a scene shot. Author the look INSIDE the shot (`post.grain`, `post.vignette`, `post.focus`, `backdrop`, `environment`) instead. DISCOVERY: there is no built-in scene primitive to look up in list_catalog; the wrapper this operation registers appears afterwards as an ordinary INSTALLED component under the existing catalog rules. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Omitted fields keep their persisted values and the MERGED result is re-validated as a whole, so a partial edit cannot leave the shot invalid. Changing only values or asset IDs updates props and bindings and REUSES the pinned source; changing the referenced SLOT SET regenerates the wrapper manifest and registers a new immutable source version atomically. Undo restores the source reference, spec, bindings and timing together. Topology, asset bindings, text content, font properties, device kind and colours are STATIC within a shot's animation — change them here (a revised spec) rather than trying to animate them. This is not a source trim or slip: a shortened or extended clip resamples the SAME normalized animation over its new duration, and trim/slip requests on generated animation are rejected rather than reinterpreted as media trims. In one batch, `scene.update` may target a shot added by an earlier `scene.add`. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Each keyframe's optional `ease` shapes the segment ARRIVING at it, in HyperFrames' vocabulary: `none` (linear, the default), named eases such as `power2.out`, `back.out`, `expo.inOut`, `spring-gentle`, `hold`, or `custom(M0,0 Cx1,y1 x2,y2 1,1)` (a cubic, x in [0,1]). Before its first keyframe a channel holds its first value, after its last it holds the last; a channel OVERRIDES the clip's scalar (`opacity`, `scale`, `rotation`, `position`). The op REPLACES that property's keyframes; other channels are untouched. Volume keyframes are linear and only for a video or audio media clip. Trims and splits keep every keyframe on its content.

The host validates the scene, generates and registers an immutable wrapper component source, and emits the ordinary track/clip operations carrying `props.componentRef` — you edit a scene SPEC, never wrapper TSX or a source hash. Registration and the composition update are ONE undoable edit; a failure publishes nothing and leaves no clip pointing at an unresolved source. REQUIRED: `clipId`, `startTime`, `duration`, `scene` and `assets` (send `{}` when no layer references a slot), plus EXACTLY ONE of `trackId` (an existing dedicated scene track) or `newTrack: true` (mint one). A minted scene track is appended at the BACK like every new track, so it paints under existing tracks; raise it with `reorderTracks` (index 0 is the top layer). That track holds scene-shot clips and gaps only — no generic component/primitive/media clips in v1 — and existing generic overlay tracks are unaffected. Scene clips use front zPlane and full-frame placement: outer per-clip `region`, `position`, `scale`, `rotation`, `fit`, `effects`, keyframes (`tweens`/`automation`), `params.transition`, `params.sequenceGroup` and internal fadeIn/fadeOut are REFUSED with a path, because the shot's own layer transforms are the single transform owner. TEXT: `space: \"screen\"` text is composed above the world result, stays fixed in the frame and stays sharp through focus; `space: \"world\"` text is rasterized into the 3D scene, moves with the camera and is occluded by geometry. Screenshots and world text are UNLIT and colour-managed so product UI colours are not tinted by the studio lighting, while device bodies are lit and cast shadows; an unlit surface still occludes. SCOPE GAP (pre-existing, neither closed nor changed by scene shots): global wrap effects — composition-level grades and camera effects — do not reach front-overlay clips, so they do not affect a scene shot. Author the look INSIDE the shot (`post.grain`, `post.vignette`, `post.focus`, `backdrop`, `environment`) instead. DISCOVERY: there is no built-in scene primitive to look up in list_catalog; the wrapper this operation registers appears afterwards as an ordinary INSTALLED component under the existing catalog rules. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Omitted fields keep their persisted values and the MERGED result is re-validated as a whole, so a partial edit cannot leave the shot invalid. Changing only values or asset IDs updates props and bindings and REUSES the pinned source; changing the referenced SLOT SET regenerates the wrapper manifest and registers a new immutable source version atomically. Undo restores the source reference, spec, bindings and timing together. Topology, asset bindings, text content, font properties, device kind and colours are STATIC within a shot's animation — change them here (a revised spec) rather than trying to animate them. This is not a source trim or slip: a shortened or extended clip resamples the SAME normalized animation over its new duration, and trim/slip requests on generated animation are rejected rather than reinterpreted as media trims. In one batch, `scene.update` may target a shot added by an earlier `scene.add`. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Each keyframe's optional `ease` shapes the segment ARRIVING at it, in HyperFrames' vocabulary: `none` (linear, the default), named eases such as `power2.out`, `back.out`, `expo.inOut`, `spring-gentle`, `hold`, or `custom(M0,0 Cx1,y1 x2,y2 1,1)` (a cubic, x in [0,1]). Before its first keyframe a channel holds its first value, after its last it holds the last; a channel OVERRIDES the clip's scalar (`opacity`, `scale`, `rotation`, `position`). The op REPLACES that property's keyframes; other channels are untouched. Volume keyframes are linear and only for a video or audio media clip. Trims and splits keep every keyframe on its content.

Each keyframe's optional `ease` shapes the segment ARRIVING at it, in HyperFrames' vocabulary: `none` (linear, the default), named eases such as `power2.out`, `back.out`, `expo.inOut`, `spring-gentle`, `hold`, or `custom(M0,0 Cx1,y1 x2,y2 1,1)` (a cubic, x in [0,1]). Before its first keyframe a channel holds its first value, after its last it holds the last; a channel OVERRIDES the clip's scalar (`opacity`, `scale`, `rotation`, `position`). The op REPLACES that property's keyframes; other channels are untouched. Volume keyframes are linear and only for a video or audio media clip. Trims and splits keep every keyframe on its content. Keyframes are stored as HyperFrames tweens (`tweens`) and automation (`automation`) on the clip; author them with this op, not `clip.update`.",

-        "description": "Author a scene shot and place it on a dedicated overlay track. The host validates the scene, generates and registers an immutable wrapper component source, and emits the ordinary track/clip operations carrying `props.componentRef` — you edit a scene SPEC, never wrapper TSX or a source hash. Registration and the composition update are ONE undoable edit; a failure publishes nothing and leaves no clip pointing at an unresolved source. Pass EXACTLY ONE of `trackId` (an existing dedicated scene track) or `newTrack: true` (mint one). That track holds scene-shot clips and gaps only — no generic component/primitive/media clips in v1 — and existing generic overlay tracks are unaffected. Scene clips use front zPlane and full-frame placement: outer per-clip `region`, `position`, `scale`, `rotation`, `fit`, `effects`, keyframes (`tweens`/`automation`), `params.transition`, `params.sequenceGroup` and internal fadeIn/fadeOut are REFUSED with a path, because the shot's own layer transforms are the single transform owner. TEXT: `space: \"screen\"` text is composed above the world result, stays fixed in the frame and stays sharp through focus; `space: \"world\"` text is rasterized into the 3D scene, moves with the camera and is occluded by geometry. Screenshots and world text are UNLIT and colour-managed so product UI colours are not tinted by the studio lighting, while device bodies are lit and cast shadows; an unlit surface still occludes. SCOPE GAP (pre-existing, neither closed nor changed by scene shots): global wrap effects — composition-level grades and camera effects — do not reach front-overlay clips, so they do not affect a scene shot. Author the look INSIDE the shot (`post.grain`, `post.vignette`, `post.focus`, `backdrop`, `environment`) instead. DISCOVERY: there is no built-in scene primitive to look up in list_catalog; the wrapper this operation registers appears afterwards as an ordinary INSTALLED component under the existing catalog rules. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Coordinates are REFERENCE PIXELS: origin at frame centre, +X right, +Y down, +Z toward the viewer. referenceSize must have the SAME aspect ratio as the composition format; mismatch fails instead of cropping. At equal aspect ratio the shot scales uniformly by outputWidth/referenceWidth. A segment's easing belongs to the keyframe it ARRIVES at; the first keyframe has no easing.

Send a replacement `scene` and/or `assets`; timing changes use the ordinary clip timing fields (`startTime`, `duration`, `transitionIn`). Omitted fields keep their persisted values and the MERGED result is re-validated as a whole, so a partial edit cannot leave the shot invalid. Changing only values or asset IDs updates props and bindings and REUSES the pinned source; changing the referenced SLOT SET regenerates the wrapper manifest and registers a new immutable source version atomically. Undo restores the source reference, spec, bindings and timing together. Topology, asset bindings, text content, font properties, device kind and colours are STATIC within a shot's animation — change them here (a revised spec) rather than trying to animate them. This is not a source trim or slip: a shortened or extended clip resamples the SAME normalized animation over its new duration, and trim/slip requests on generated animation are rejected rather than reinterpreted as media trims. In one batch, `scene.update` may target a shot added by an earlier `scene.add`. ASSETS: `assets` binds each slot name a layer references to a media id in the same project, and the slot's declared KIND decides what it admits — an image slot takes PNG, JPEG or WebP, a video slot MP4 or WebM. Binding the wrong kind is refused with the slot's path.",

Coordinates are REFERENCE PIXELS: origin at frame centre, +X right, +Y down, +Z toward the viewer. referenceSize must have the SAME aspect ratio as the composition format; mismatch fails instead of cropping. At equal aspect ratio the shot scales uniformly by outputWidth/referenceWidth. A segment's easing belongs to the keyframe it ARRIVES at; the first keyframe has no easing.

A3.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the tool is mutating, non-read-only, non-destructive, and not idempotent. The description adds important behavioral context about concurrency guards, revision basis, journal identity, and the distinction between session command identity and HTTP request identity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the commit action and uses only three dense sentences. Each sentence carries useful identity or concurrency information, though the phrase 'guarded composition fields' is slightly vague.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a nested mutation with no output schema, the description supplies the key concurrency and identity constraints needed to call it correctly. It does not fully explain the composition operations or sibling routing, but annotations cover safety and the schema covers required fields.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 67%, and the nested composition schema is only a pointer to describe_tool_input. The description compensates by explaining the critical relationship composition.commandId = composition.clientId + ':' + composition.sequence and by distinguishing the top-level commandId as a separate request identity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: committing an integrated editorial edit to a saved project composition. It is clearly not a read or listing tool, but it does not explicitly differentiate itself from the similar sibling apply_composition.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no explicit when-to-use guidance, prerequisites, or alternatives. It implies this is a commit step after editorial integration, but never says when to choose it over apply_composition or related editorial tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
