set_clip

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

No annotations are provided, so the description carries the full behavioral burden. It does not state whether the clip must already exist, what happens to unset fields (the schema defaults them to null), whether changes are reversible, or any permission/error behavior for a mutation tool.

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?

A single efficient sentence that front-loads the primary operation (rename) and lists the remaining options compactly with no filler. It reads as a field list rather than a structured statement, but nothing is wasted.

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?

For a 7-parameter mutation tool with no annotations and no output schema, the description is too thin. It omits required-parameter meaning, any return/error behavior, and the interaction between optional fields, so an agent cannot confidently invoke it in all cases.

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 0%, so the description must compensate. It meaningfully maps to five of seven parameters (name, loop_start/loop_end as 'loop region (beats)', looping, color_index) and even gives a unit hint ('beats'). However the two required parameters, track_index and slot_index, are never explained, leaving a real gap.

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 names a specific resource (clip) and enumerates concrete operations: rename, loop region, looping on/off, color. This clearly separates it from create_clip, delete_clip, and duplicate_clip. However it does not differentiate itself from the very similar sibling set_audio_clip, leaving ambiguity between the two.

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?

There is no statement of when to use this tool versus alternatives such as set_audio_clip, create_clip, or set_clip_automation. The description only lists what can be changed, providing no context, prerequisites, or exclusions to guide selection.

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