add_task_label

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

With no annotations available, the description must fully disclose behavior. 'Attach' implies a mutating operation, but it does not mention effects such as whether an existing label is replaced, permission requirements, or idempotency. No side effects or return behavior are described, leaving an agent uncertain about the operation's semantics.

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, which is concise and front-loaded, but it is under-specified rather than efficiently detailed. It earns no extra credit for structure because it omits critical context that could be added without verbosity.

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 simple two-parameter tool, the description covers the basic action but lacks any guidance on parameter semantics, behavioral outcomes, or usage context. Without an output schema or annotations, an agent would need to guess how to use this tool correctly, making it incomplete.

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 elaborate on the two parameters, taskId and labelId. The names are suggestive but not explained (e.g., what kind of IDs, how they are obtained, or constraints). Since the schema offers no descriptions either, the agent has no additional semantic context to correctly fill these parameters.

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 ('Attach') and resource ('a label to a task'), making the intent unambiguous. It differentiates from its direct sibling remove_task_label by direction (attach vs remove), though it does not explicitly name that sibling or any other alternative.

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 use this tool versus alternatives like create_label, add_assignee, or remove_task_label. It neither states explicit conditions, prerequisites, nor exclusions. The context is only implicitly inferable from the tool's name and sibling set.

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