set_source_in_out

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

Annotations indicate readOnlyHint=false and destructiveHint=false, consistent with modifying in/out points. The description adds context (operates on source monitor clip) but does not disclose error conditions, prerequisites, or side effects beyond the modification.

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 is concise and front-loads the key action. It contains no unnecessary words, though it could be slightly more structured to improve readability.

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?

The description covers the core purpose adequately for a simple tool with no output schema. However, it does not mention that both parameters are optional, what happens if neither is provided, or that a clip must be open in the source monitor. Missing details for full 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?

Input schema coverage is 100% with both parameters described. The description does not add additional meaning beyond the schema; it merely restates that in and/or out points can be set, which is already clear from parameter names and descriptions.

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 verb 'set' and the resource 'in and/or out points on the clip currently open in the Source Monitor'. It differentiates from siblings like 'set_item_in_out' (likely for timeline) and 'clear_item_in_out'.

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 on the source monitor clip, but does not explicitly state when to use this tool versus alternatives like 'set_item_in_out' or 'clear_item_in_out'. No exclusions or alternative tool names are provided.

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