Update Theme

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

The description discloses a behavioral detail beyond the openWorldHint annotation by stating 'Returns an operation_id', which hints at an asynchronous workflow. However, it does not explain what the operation_id means, whether the update is destructive/reversible, or any permissions, so the full behavioral burden is not met.

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?

One concise sentence conveys the action, scope, and return value. There is no filler or redundancy, and the key information is front-loaded.

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 simple mutation with three fully described parameters, the description covers the action and return value, but it omits the asynchronous operation-tracking context implied by operation_id and does not resolve the latest-version versus update_version ambiguity. This makes it only minimally complete.

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 coverage is 100%, so the baseline is 3, but the description's 'latest version' conflicts with the schema's required update_version described as 'The theme version to install'. Rather than adding parameter meaning, it introduces ambiguity about what the version argument should contain.

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 uses a clear verb and resource: 'Update a single theme' and states it returns an operation_id. It distinguishes from bulk siblings such as kinsta_themes_bulk-update by saying 'single', though it does not name the sibling explicitly. The phrase 'to the latest version' slightly conflicts with the required update_version parameter, preventing a 5.

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 word 'single' implies this is for one theme rather than the bulk-operation sibling, but the description does not explicitly say when to prefer this over kinsta_themes_bulk-update or provide exclusions. Usage is implied rather than clearly stated.

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