add_task_comment

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

Annotations only include openWorldHint=false and destructiveHint=false, leaving the mutating nature unclear beyond the verb 'add'. The description does not disclose additional behavioral traits such as whether the comment is appended or replaces existing comments, how invalid task IDs are handled, or any permission requirements. With minimal annotation coverage, the description carries a heavy burden it fails to meet.

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 concise, with a single opening line and a clean parameter list. Every sentence adds value, and it is front-loaded with the purpose. No redundancy or fluff.

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 is simple (2 flat parameters) and an output schema exists, so return details are unnecessary. The description covers the operation and parameter semantics sufficiently for a straightforward write action. Missing context like task existence validation or idempotency is minor given the simplicity.

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 input schema has no descriptions (0% coverage), but the description fully compensates by explaining both parameters: task_id format (custom like DEV-1234 or UUID) and comment_text (plain text). This goes beyond the schema and is essential for correct usage.

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 clearly states the tool adds a comment to a task, using a specific verb ('add') and resource ('task'). It is distinct from sibling tools like get_task_comments (reading) and update_task (modifying task properties), so there is no ambiguity.

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 its use case clearly: when you need to attach a comment to a task. It does not explicitly mention alternatives or when not to use it, but the operation is self-evident, making the usage context clear without exclusions.

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