Instructions

Set the name of a clip.

Parameters:

  • clip_index: The index of the clip slot containing the clip

  • name: The new name for the clip

Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool performs a write operation ('Set'), implying mutation, but doesn't disclose permissions needed, whether changes are reversible, error conditions (e.g., invalid indices), or side effects. The description lacks behavioral context beyond the basic action.

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 extremely concise and well-structured: a clear purpose statement followed by a bulleted list of parameters with brief explanations. Every sentence earns its place, with no redundant or verbose language. It's front-loaded with the core action.

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?

Given 3 parameters with 0% schema coverage and no annotations/output schema, the description provides basic parameter semantics but lacks behavioral context. For a mutation tool with no structured safety hints, it should ideally mention permissions, error handling, or side effects. The description is minimally adequate but has clear gaps in completeness.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must compensate. It explicitly lists all three parameters with brief explanations: 'track_index' (index of track containing clip), 'clip_index' (index of clip slot containing clip), and 'name' (new name for clip). This adds meaningful semantics beyond the schema's bare types, though it doesn't specify index ranges or name constraints.

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

Purpose4/5

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

The description clearly states the action ('Set the name') and resource ('of a clip'), making the purpose immediately understandable. It distinguishes from siblings like 'set_track_name' by specifying it operates on clips rather than tracks. However, it doesn't explicitly differentiate from tools like 'create_clip' or 'add_notes_to_clip' in terms of scope.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., clip must exist), exclusions (e.g., cannot rename non-existent clips), or related tools like 'set_track_name' for track-level operations. Usage context is implied but not explicitly stated.

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