set_clip_name

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

With no annotations provided, the description carries the full behavioral burden. "Rename" implies a mutation, but there is nothing about permissions, whether the existing name is overwritten irreversibly, error behavior for an empty/occupied slot, or what the call returns.

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 compact sentence with the verb and resource front-loaded and zero wasted words. It is appropriately sized, though its brevity borders on under-specification for a 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?

The tool is simple, all three parameters are documented in the schema, and there is no output schema to explain. Still, with no annotations and no behavioral detail, the definition is only minimally complete for an agent to call it correctly in edge 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 description coverage is 100% – name, clip_index, and track_index are all documented in the schema, including the 0-indexed convention. The description adds no additional meaning (no naming constraints, no length limits), so the baseline 3 applies.

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 ("Rename") and resource ("a clip in a clip slot"), which is clear enough that an agent can distinguish it from siblings like set_track_name or set_clip_color. However, it does not explicitly differentiate itself from those analogues in the text, making it clear but not maximally disambiguating.

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 gives no when-to-use guidance, no prerequisites (e.g. clip slot must exist), and no mention of alternatives such as bulk_edit_clips. The agent must infer usage entirely from the name.

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