update_tag

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

With no annotations, the description carries the full burden. It does add real value by disclosing the `tags:manage` permission requirement and the underlying PUT endpoint semantics, but it says nothing about side effects (e.g., whether renaming a tag affects conversations already carrying it), error behavior, or idempotency.

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?

It is short and front-loaded, but two of the four lines are filler: 'Update Tag' repeats the tool name and 'Tags: Tags' is a redundant category label. The genuinely useful line, the permission requirement, is buried in the middle.

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 two-parameter, non-nested mutation with a fully described schema and no output schema, the definition covers the essentials an agent needs: the endpoint, the target resource, and the auth requirement. It falls short only on side-effect disclosure, which for a rename operation would have been worth a sentence.

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 both parameters (id as path parameter, name with a non-empty constraint and example) are already documented. The description adds no meaning beyond the schema, which is acceptable at this coverage level but not a contribution.

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 says 'Update Tag' and gives the endpoint PUT /api/v1/tags/{id}, so the resource and the mutation are identifiable, but the opening line merely restates the tool name and nothing distinguishes it from siblings such as create_tag or update_conversationtags beyond the endpoint path. No mention of what part of a tag is updatable.

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 on when to call this versus create_tag, delete_tag, or the other update_* tools. The only context given is the required permission, which is a prerequisite rather than a usage policy, and there are no exclusions or alternatives named.

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