TDQS

B3.3/5.0
Behavior2/5

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

The annotations are sparse (all false hints), so the description carries the burden of behavioral disclosure. It only restates the core action and does not reveal important behavioral traits such as whether selecting a clip clears the existing selection, whether deselecting a non-selected clip is a no-op, or what happens if no active sequence exists. The description adds little beyond the schema and annotation hints.

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

Conciseness5/5

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

The description is a single concise sentence that immediately states the action and scope. There is no filler, no repetition of the tool name, and no unnecessary detail.

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

Completeness3/5

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

For a simple two-parameter tool with full schema coverage and an output schema, the description is minimally adequate. However, it omits side-effect behavior (clearing prior selection) and usage context relative to sibling selection tools. These gaps prevent it from being fully complete.

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

Parameters3/5

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

Schema description coverage is 100%, with node_id and selected already clearly documented. The description's 'select or deselect' wording echoes the selected boolean semantics but does not add meaningful new meaning. Baseline 3 is appropriate because the schema handles parameter documentation.

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

Purpose5/5

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

The description states a specific action ('Select or deselect') applied to a clearly scoped resource ('a clip in the active sequence'). This distinguishes it from related selection tools like select_item, get_selected_clips, and select_clips_by_name, whose scopes or operations differ.

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

Usage Guidelines2/5

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

The description gives no guidance on when to use this tool versus the many sibling selection tools (e.g., select_all_clips, select_clips_in_range, deselect_all_clips, invert_selection). It does not mention prerequisites such as having an active sequence, nor does it explain when a simple single-clip select/deselect is or is not appropriate.

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