regenerate_magic_mask

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

With no annotations, the description carries the full burden. It only says 'regenerate', implying modification, but does not disclose side effects, what happens if no mask exists, or any destructive behavior.

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 with one sentence and a parameter list, but the list does not add detail beyond the schema. It is minimally acceptable but could be more concise or structured better.

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 3 parameters with no schema descriptions, no annotations, and an output schema not mentioned, the description is incomplete. It lacks details on what regenerating entails, expected output, or error conditions.

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 0%, so the description must compensate. It adds only 'Clip locator' as a label for the three parameters, which provides minimal context and does not explain each parameter's meaning or constraints (e.g., valid values for track_type).

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 'regenerate' and the resource 'existing Magic Mask on a timeline item'. It distinguishes the operation from creating a new mask implicitly, but does not explicitly differentiate from the sibling tool 'create_magic_mask'.

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 like 'create_magic_mask'. There is no mention of prerequisites (e.g., mask must exist) or exclusions.

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