apps__update

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

The description includes the HTTP method 'PATCH', indicating a partial update, which adds behavioral context beyond the annotations. However, it does not disclose other traits like required permissions, rate limits, or side effects. Since annotations already declare idempotency and non-destructiveness, the description adds minimal extra value.

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 (one sentence) and front-loaded with the key action. It could be slightly more informative (e.g., mentioning updatable fields) but remains concise and efficient.

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 complexity (nested objects, no output schema), the description is insufficient. It does not explain what the response returns, nor does it provide any usage hints or examples. The schema fills the structure, but the description lacks completeness for a mutation tool.

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 baseline is 3. The description does not add any parameter-specific information beyond what is in the schema. It provides no extra meaning or usage context for parameters like 'id' or 'body'.

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 'Update an app,' specifying the verb (update) and resource (app). The name and description distinguish it from sibling tools like apps__get or apps__list, though it doesn't differentiate from other update tools like app_infos__update, but those update different resources.

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 given on when to use this tool vs alternatives. The description does not mention prerequisites, context, or exclusions. There is no comparison to siblings like apps__get or app_infos__update.

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