create_bars_and_tone

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

With no annotations provided, the description carries full burden. It states the tool creates a synthetic media item but does not disclose side effects (e.g., where the item is placed, whether it modifies the timeline, any dependencies or required states). The lack of detail on what 'create' entails limits transparency.

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 concise sentence that communicates the core purpose. It is front-loaded and efficient, though it could be slightly more structured to include brief usage notes without becoming verbose.

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 tool's simplicity (4 optional parameters, no output schema), the description adequately states what it creates and why. However, it does not clarify the outcome (e.g., whether the item appears in a bin or timeline) or handle any edge cases, leaving some contextual gaps.

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?

The input schema covers all 4 parameters with descriptions, so baseline is 3. The description adds no parameter-specific information, but since schema coverage is 100%, it does not need to compensate. The description does not reiterate parameter meanings.

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 action ('Create'), the resource ('Bars and Tone synthetic media item'), and its purpose ('useful for leader/calibration'). It distinguishes itself from sibling tools like 'add_text_overlay' or 'create_subclip' by specifying the exact type of item created.

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 implies usage for leader/calibration but does not provide explicit guidance on when to use or avoid this tool. No alternatives are mentioned, and there is no mention of prerequisites or contexts where this tool is inappropriate.

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