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

No annotations exist, so the description carries the full burden. It conveys that this is a create operation but discloses nothing else: no mention of return value, idempotency, whether it appends to existing comments, error behavior, or required permissions. This is a mutation tool with zero behavioral context beyond the verb 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?

A single sentence with no wasted words, and the key action is front-loaded. It is appropriately terse for a simple two-parameter create operation, though one additional clause about the return value or behavior would not have degraded readability.

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 tool with only two required parameters and no nested objects, the description is minimally adequate. However, with no annotations and no output schema, the agent is left guessing about success behavior, return value, and failure conditions — gaps that matter for a write operation.

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 two undocumented parameters. It only loosely maps comment and task_id through the phrase 'a comment to a task,' which adds little beyond what the parameter names already imply. No constraints, formats, or edge-case semantics are clarified.

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 a specific verb ('Add') with a clear resource ('a comment') and target ('a task'), making the core purpose unambiguous. It implicitly distinguishes from siblings like update_comment, delete_comment, and list_comments through the verb choice, though it never names them explicitly.

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 on when to use this tool versus alternatives. It doesn't contrast with update_comment (modify existing) or list_comments (read), and provides no context about when adding is appropriate.

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