update_label

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only restates that the tool updates a label, without explaining effects on existing label details, whether the update is partial or full, permission requirements, or idempotency. The description adds no behavioral context beyond the tool name itself.

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 extremely short, but this is under-specification rather than useful conciseness. It contains no structure or details that help an agent select or invoke the tool correctly.

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 mutation tool with four parameters, two required fields, no schema descriptions, and no annotations, the description is grossly incomplete. It omits parameter semantics, required identifiers, and behavioral effects, so an agent cannot reliably construct a valid call.

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%, so the description must compensate for the lack of parameter documentation, but it does not. It never mentions account_id, label_id, color, or display_name, leaving the agent to guess what 'details' means and what values are expected.

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 the verb 'update' and the resource 'label,' so an agent can roughly tell this is the mutation counterpart to create/get/delete label tools. However, 'details' is vague and gives no indication of which label properties can be changed. It is clear enough at a high level but lacks specificity.

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 provides no guidance on when to use this tool versus sibling tools like create_label, get_label_details, or delete_label. It also does not mention that account_id and label_id are required prerequisites or that color/display_name are the updatable fields.

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