set_clip_selection

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

The description adds minimal behavioral context beyond annotations. While annotations indicate readOnlyHint=false and destructiveHint=false, the description does not clarify how this tool interacts with existing selections (e.g., whether it clears other selections) or any side effects. No contradictions with annotations.

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 front-loads the core purpose with no superfluous words. Every word adds value.

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 simple nature of this tool and absence of output schema, the description is nearly complete. It could be improved by briefly noting that it sets the selection state of a single clip, but the current version suffices for minimal understanding.

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% with both parameters described. The description adds no extra meaning beyond the schema. For a simple boolean parameter, this is adequate but not enhanced.

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 'Select or deselect a clip in the active sequence' clearly states a specific verb (select/deselect) and resource (clip in active sequence). It effectively distinguishes this tool from siblings like select_all_clips and deselect_all_clips by indicating per-clip action.

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 selecting or deselecting individual clips but provides no explicit guidance on when to use this tool versus alternative selection tools (e.g., select_all_clips, select_clips_by_name). No exclusions or conditions are mentioned.

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