Set Sequence Display Format

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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, and idempotentHint=false. The description adds the scoping detail that the change applies to the active sequence, but it does not explain persistence, error behavior, or whether the setting affects only display versus underlying media.

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?

A single sentence, front-loaded with the action and target. Every word is necessary and there is no redundant or vague filler.

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?

For a simple, low-complexity setter with rich schema descriptions, annotations, and an output schema, the definition is nearly complete. It could mention that audio and video formats are independently settable or what happens when parameters are omitted, but those details are arguably covered by the schema.

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 description coverage is 100%, so both audio_display_format and video_display_format are fully documented in the schema, including their numeric mappings. The description adds no additional parameter meaning beyond what the schema already provides, making the baseline 3 appropriate.

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 states a specific verb and resource: 'Set the timecode display format for the active sequence.' It clearly distinguishes this from sibling setters like frame rate, resolution, and audio settings, though it does not explicitly name an alternative tool.

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?

There is no guidance on when to use this tool versus alternatives such as set_sequence_settings or set_sequence_frame_rate. The phrase 'for the active sequence' implies a prerequisite, but no explicit when/when-not instruction is provided.

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