update_tag

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

No annotations are present, so the description carries full responsibility for disclosing behavioral traits. It does not mention whether the update is partial or complete, what happens to items associated with the tag, error conditions, or permissions. For a mutation tool, this is a significant gap.

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 sentence, front-loaded, with no filler. It conveys the essential action and scope efficiently, earning a high score for conciseness.

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 tool with 3 parameters and no output schema, the description is minimal and lacks important details such as update semantics (partial vs full replacement), whether name/color are optional, and potential side effects on associated items. Given its low complexity, the gap is noticeable but not catastrophic.

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?

The schema descriptions are tautological ('name parameter', 'color parameter'), offering no meaning. The description adds some value by clarifying that 'name' and 'color' are the updatable attributes and that 'and/or' implies partial updates. However, it does not explain whether at least one of name/color is required or provide any constraints like color format.

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 the specific verb 'update' and resource 'tag', and specifies the modifiable fields ('name and/or color'), clearly distinguishing it from siblings like add_tag, remove_tag, and delete_tag. It is unambiguous about what the tool does, though it could be more explicit that it targets an existing tag via tag_id.

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 usage: change a tag's name or color. However, it does not explicitly state when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. The purpose is self-evident from the name and description, but no explicit guidance is provided.

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