caption_style_load

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

Annotations already mark the tool as destructive and non-read-only; the description adds useful specifics by stating it replaces the project's current style and that undo can revert the change. This gives an agent a clearer risk picture than the annotations alone.

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 very short and front-loads the key behavior plus undo. However, the first sentence is awkwardly phrased and would be clearer with a noun like 'style' or 'look' explicitly resolving what is replaced.

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 schema and output schema cover parameters and return shape, so the main description does not need to explain those. It is missing a clearer statement of its relationship to caption_style_save and caption_style_library, and the ambiguous purpose wording leaves an agent to infer exact semantics.

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 the parameters are already well-documented. The main description adds no further parameter-level detail, which is acceptable given the rich schema descriptions for name, path, and plan.

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 implies the tool applies a saved caption look to the project and replaces the current one, but the phrase 'Make a saved caption look this project's' is ungrammatical and obscures the subject/object relationship. It does not distinguish itself from similar sibling tools like caption_style_save beyond the 'replacing' wording.

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?

Usage is implied: use this tool to apply a saved caption look to the project. However, there is no explicit guidance on when to choose this over alternatives, and no exclusions or prerequisites are stated. The 'Prefer plan' note in the schema adds some operational guidance but does not address tool selection.

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