set_clip_metadata

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It does not specify whether the operation overwrites existing metadata, requires specific permissions, or what happens if the clip is not found. The tool's mutability is implied but not detailed.

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 short and front-loads the purpose, but it redundantly repeats the Args list which is already in the schema. This slightly bloats the text without adding unique value. It is adequately concise but not optimally 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 modifies data (no readOnlyHint) and has two parameters with 0% schema coverage, the description is incomplete. It does not explain the return value (though an output schema exists), error cases, or the effect on existing metadata. More context is needed for safe and correct usage.

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 description adds brief explanations for both parameters: 'clip_name: The name of the clip to update' and 'metadata: Dictionary of metadata field names to values.' This provides some meaning beyond the raw schema, especially for 'metadata' as a dictionary. However, it lacks details on valid field names, value types beyond strings, and required fields.

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 verb 'Set' and the resource 'metadata fields on a clip in the current Media Pool folder'. This distinguishes it from sibling tools like 'get_clip_metadata' (read) and 'set_clip_metadata_batch' (batch operation). The purpose is specific and unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites (e.g., clip must exist, current folder must be set) or scenarios where other tools like 'set_clip_metadata_batch' would be more appropriate. The description lacks usage context.

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