update_tag

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

The annotations already declare that this is a non-read-only, open-world, non-idempotent, non-destructive mutation. The description adds useful partial-update semantics by explaining that attributes are optional and omitted attributes retain their original values, but it does not cover permissions, response behavior, or rate limits.

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 operation and endpoint. There is slight redundancy between the first sentence and 'Update attributes to your tag,' but no wasted paragraphs.

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 annotations and fully described schema give enough context to invoke the tool correctly, and the partial-update note is useful. However, with no output schema, the description does not explain what the update returns, and it does not route the agent away from sibling tag tools.

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 schema already documents tagId, x-trace-id, and the nested body properties. The description adds some semantic value by clarifying that body attributes are optional and preserve existing values when omitted, but it does not add format or validation detail beyond the schema.

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 states a specific verb and resource: update a tag, scoped by id and mapped to PATCH /v1/tags/{tagId}. It is clear what the tool does, though it does not explicitly distinguish itself from sibling operations such as create_tag, retrieve_tag, or delete_tag.

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 description implies the tool updates an existing tag, but it gives no explicit guidance on when to use it versus alternatives, nor does it state prerequisites or when not to use it.

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