Rotate or flip video

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

The description states the input video is not modified, which is good, but does not mention the potential for overwriting an existing output path (noted in parameter description). The annotation destructiveHint=true is not fully explained in the description, though it may refer to output overwriting. Overall, basic disclosure but missing some behavioral details.

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

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

The description is a single sentence that efficiently conveys the core purpose and supported operations. No unnecessary words, front-loaded with the verb 'rotate and/or flip'.

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

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

Given the presence of an output schema (context signal) and full parameter documentation, the description is nearly complete. It lacks details about output format or codec, but those are likely covered by the output schema. Slightly more context on when to use this tool would improve completeness.

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

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

Schema coverage is 100% and parameters are well-documented in the schema itself. The description adds no additional meaning beyond what the schema provides, so it meets the baseline expectation.

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

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

The description clearly states the tool rotates and/or flips an existing video and renders a new output file, specifying supported operations (right-angle rotations, horizontal/vertical flips). It distinguishes itself from sibling tools like video_crop or video_resize by focusing on orientation changes.

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

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

The description provides no explicit guidance on when to use this tool vs alternatives (e.g., video_crop, video_resize). It is implied by the name and description, but no when-not-to-use or sibling comparisons are given.

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