set_clip_in_out

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

With no annotations, the description carries the full behavioral burden and discloses very little. It doesn't say whether omitting inPoint or outPoint clears that bound, whether outPoint must be greater than inPoint, whether the trim affects only the timeline instance or the source, or whether the operation is undoable.

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 front-loaded sentence with no filler. It is efficient, though its brevity borders on under-specification for a five-parameter mutation tool.

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 parameterized clip mutation with no annotations and no output schema, the description is too thin. The agent still lacks the effect of partial in/out specification and the relationship to the many neighboring in/out tools.

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 all five parameters are documented in the schema; the baseline is 3. The phrase 'source in/out points' does add a useful distinction (source-relative vs. timeline-relative), but it doesn't clarify the semantics of the optional pair being omitted.

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?

States a specific verb and resource ('Trim a clip by setting its source in/out points'), which tells an agent exactly what changes. It does not, however, distinguish itself from close siblings like set_project_item_in_out, set_source_in_out, or set_sequence_in_out, which an agent must resolve on its own.

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, no prerequisites, and no named alternative. The crowded sibling set (set_source_in_out, set_project_item_in_out, set_sequence_in_out, clear_project_item_in_out) makes this omission costly for selection.

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