set_clip_loop

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

No annotations are provided, so the description carries the full burden. It fails to disclose any behavioral traits beyond the obvious mutation (e.g., whether it requires an existing clip, if it affects playback, or if changes are reversible). The description adds no value over the parameter names.

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 concise, using a single sentence to state the purpose followed by a parameter list. It is front-loaded and avoids unnecessary words, though the list format could be slightly more structured.

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 tool has 5 parameters and no output schema, the description lacks important context such as the effect of enabling looping, default behaviors, or any prerequisites. It is too sparse for an agent to use effectively.

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?

With 0% schema description coverage, the description must compensate but merely lists parameter names without adding any semantic meaning. It does not explain units (e.g., beats for loop_start/loop_end), relationships, or constraints. This is insufficient.

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 'Set the loop settings of a clip', which is a specific verb-resource combination that distinguishes it from sibling tools like set_clip_color, set_clip_gain, etc. It unambiguously identifies the tool's purpose.

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 provides no guidance on when to use this tool versus alternatives. For a tool with many siblings focused on clip modifications, the lack of usage context or exclusions is a significant gap.

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