update_tag

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

Annotations already indicate this is a non-read-only, non-destructive, non-idempotent operation. The description adds no further behavioral context, such as whether the rename overwrites the existing name, affects tag-user associations, or requires special permissions. It merely restates that the name is updated.

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 a single short sentence that conveys the core operation immediately. It is efficient and front-loaded, with no wasted words.

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?

With two required parameters, zero schema descriptions, and no usage guidance, the description is too sparse for an agent to call the tool confidently. An output schema exists, so return values need not be explained, but parameter semantics and operation context are still missing.

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%, and the description does not explicitly define tag_id or name. The phrase 'update user tag name' hints that 'name' is the new tag name, but tag_id's meaning is left entirely to inference, and no value format or constraints are provided.

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 clear verb ('update') and a specific resource ('user tag name'), making the tool's primary purpose unambiguous and implicitly different from siblings like create_tag, delete_tag, or tag_users. However, it does not explicitly contrast with any sibling tool, so it falls short of the highest distinction bar.

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 about when to choose update_tag over other tag-related tools, nor any exclusions or prerequisites. The usage context is only implied by the tool name and the word 'update'.

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