add_label

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

No annotations are provided, so the description must disclose behavioral context on its own. It only implies a mutation/association and does not mention idempotency, duplicate handling, error behavior, permissions, or whether the label must pre-exist.

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, front-loaded sentence with no wasted words. It directly communicates the core operation without redundant filler or repetition of the schema.

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?

The tool itself is simple with only two integer parameters and no output schema, so a short description can be adequate. But with no annotations, no parameter descriptions in the schema, and no usage or behavioral guidance, the description only covers the minimum viable information for selecting and invoking the tool.

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. It maps the two parameters conceptually: task_id refers to the task and label_id refers to the label. However, it does not explicitly describe each parameter's meaning, constraints, or source, leaving the agent to infer the mapping from names.

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 exact action ('Attach') and the resources involved ('a label', 'a task'). This clearly distinguishes it from related siblings like create_label (creating a label definition), remove_label (removing the association), and list_labels (listing available labels).

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?

There is no guidance about when to use this tool versus alternatives such as create_label, remove_label, or add_assignee. It does not mention prerequisites like whether the label and task must already exist, or when an agent should prefer a different tool.

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