nest_clips

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

With no annotations, the description carries the full burden, yet it says nothing about side effects: whether the source clips are replaced by the nest, whether a new sequence is added to the project bin, whether the operation is undoable, or whether prior selection matters. 'Selected clips' even conflicts slightly with the index-based parameters, leaving the actual input model unclear.

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?

One sentence, front-loaded with the verb and outcome, with no filler. It is efficient, though arguably under-specified rather than genuinely concise.

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 timeline-mutating tool with four parameters, no annotations, and no output schema, the description leaves key agent questions unanswered: what happens to the original clips, where the nested sequence lands, and how this differs from subsequence creation. The structured fields cover parameter shapes, but the behavioral contract is missing.

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 description coverage is 100%, so trackType, trackIndex, clipIndices, and nestedSequenceName are all documented in the schema. The description adds nothing about parameter meaning, which is acceptable at full coverage but earns only the baseline.

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?

Specific verb (nest) plus resource (selected clips) plus result (new nested sequence), which is more precise than most sibling names. It doesn't explicitly contrast with near-neighbors like create_subsequence or create_sub_clip, so the reader must infer the distinction from the wording alone.

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 when-to-use guidance and no mention of when-not to use it or which alternatives exist. Given that create_subsequence, create_sub_clip, and consolidate_duplicates all sit in the sibling list, an agent has no textual basis for choosing nest_clips over them.

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