nest_clips

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

Annotations indicate it is not read-only, not idempotent, and not destructive, but the description does not elaborate on behavioral specifics. It lacks details on what happens to original clips, whether they are replaced or grouped, and any side effects. Given the sparse annotations, the description should provide more context.

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, with two sentences front-loading the core action and usage instruction. No extraneous words or redundancy.

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 complexity of nesting clips and lack of output schema, the description is too minimal. It does not explain the result sequence's structure, relationship to original clips, or how it differs from similar tools like 'create_sequence_from_clips'. The one parameter 'name' is straightforward, but overall context is insufficient for an AI agent to fully understand implications.

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?

The schema covers 100% of parameters with a description for 'name' already present. The tool description adds no new semantic value beyond what the schema provides, so a baseline score of 3 is appropriate.

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 the action (nest selected clips) and the outcome (nested sequence), using a specific verb and resource. It implicitly distinguishes from siblings like 'duplicate_clip' and 'unnest_sequence', but could be more explicit about when to use this over other nesting/sequence creation tools.

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 a precondition ('Select the clips first, then call this tool'), which guides when to use it. However, it does not mention when not to use it or suggest alternatives (e.g., 'create_sequence_from_clips' or 'create_subsequence'), which would help with decision-making.

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