Apply a camera preset

keyshot_apply_camera_preset

Destructive

Apply a standard-view or absolute camera preset to a KeyShot scene, create or update a saved camera, then save the edited scene.

Instructions

Create or update a saved camera from a configured standard-view or absolute camera preset, then save the edited scene.

Input Schema

TableJSON Schema

Name	Required	Description
`scenePath`	Yes	Absolute path to an existing KeyShot scene file to open. Input files may be outside the configured output directory.
`cameraName`	No	Optional saved camera name. Defaults to the preset name.
`presetName`	Yes	Case-insensitive camera preset name returned by keyshot_list_camera_presets.
`outputScenePath`	Yes	Destination path for the saved KeyShot scene. The path must stay inside KEYSHOT_OUTPUT_DIR unless external outputs are explicitly enabled.

Output Schema

TableJSON Schema

Name	Required	Description
`ok`	Yes	True when the requested operation completed successfully.
`data`	Yes	Operation-specific structured result data, or null when unavailable.
`error`	Yes	Human-readable failure reason, or null after success.
`warnings`	Yes	Non-fatal conditions the user or agent should review.
`errorCode`	No	Stable error category for common failures.
`outputFiles`	Yes	Absolute paths of images or scene files created by the operation.
`suggestions`	No	Actionable recovery steps for the user or agent.
`keyshotStdoutTail`	Yes	Truncated tail of KeyShot headless output for diagnostics.

TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=false. The description adds that it creates/updates a camera and saves the edited scene, confirming the mutation, but does not elaborate on what gets overwritten, auth needs, or rate limits.

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

Conciseness5/5

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

A single, front-loaded sentence with no redundant or filler content. Every clause earns its place.

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?

Given a destructive write tool with an output schema and annotations that cover safety hints, the description states the core action and the save step. It is largely complete, though it omits how it relates to sibling camera tools.

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

Parameters3/5

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

Schema description coverage is 100%, so all four parameters are documented in the schema. The description mentions the preset concept but adds no meaning beyond the schema's parameter descriptions (e.g., cameraName default). Baseline 3 applies.

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?

States a specific verb and resource: create or update a saved camera from a preset, then save the edited scene. Clear what the tool does, but does not differentiate it from siblings such as keyshot_set_camera or keyshot_save_scene.

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

Usage Guidelines3/5

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

Usage is implied by the operation, but the description provides no explicit when-to-use guidance, no alternatives (e.g., keyshot_set_camera), and no exclusions. An agent must infer the appropriate context.

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