GetVideoFrames

Get frame extraction job

getvideoframes_get_job

Read-onlyIdempotent

Read one job by id, including presigned frame URLs while it is completed and unexpired.

Statuses: queued, processing, completed, failed, expired. Pass wait=true to block up to 50 seconds if the job is still running. When status is completed, the frame list includes download URLs. Call getvideoframes_render_frames with the same id to show the filmstrip. Call getvideoframes_get_frame with the same id and a frame index when you need to see that frame's pixels.

Tool call template

A4.9/5.0

Behavior5/5

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

Annotations cover the safety profile (readOnly, idempotent, non-destructive), and the description adds real behavioral context on top: the full status lifecycle, the 50-second blocking behavior, and the fact that URLs are presigned and expire. That expiry/blocking detail is not derivable from the structured fields.

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?

Front-loaded with the core action, followed by a compact status list and then the routing sentences. No filler; every sentence carries operational information.

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

Completeness5/5

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

No output schema exists, but the description compensates by describing what a completed response contains (frame list with download URLs). Combined with the status enumeration and sibling routing, an agent has everything needed to call and interpret this tool.

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 description coverage is 100%, so the baseline is 3. The description adds usage context for wait (blocking only matters while the job is running) and reinforces id reuse across sibling calls, going modestly beyond the schema text.

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

Purpose5/5

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

States a specific verb and resource ("Read one job by id") and immediately scopes the payload (presigned frame URLs, only while completed and unexpired). It is clearly distinguishable from list_jobs, get_frame, and render_frames.

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

Usage Guidelines5/5

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

Explicitly routes the agent: render_frames with the same id for the filmstrip, get_frame with the same id plus frame index for pixels, and wait=true when the job is still running. When-to-use and alternatives are all named.

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