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

With no annotations provided, the description lacks behavioral details. It doesn't disclose whether this is a read-only operation (implied by 'List'), potential rate limits, authentication needs, pagination behavior beyond schema defaults, or error conditions. The description carries the full burden but adds minimal context beyond the basic action.

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, efficient sentence with zero wasted words. It's front-loaded with the core action ('List comments') and includes the resource scope ('for a specific work item'), making it easy to parse quickly.

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 list operation with no annotations and no output schema, the description is minimally adequate. It specifies the resource but lacks details on return format, error handling, or behavioral traits. Given the simple nature of the tool (list comments) and full schema coverage, it meets basic needs but could be more informative.

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 100%, so parameters are well-documented in the schema. The description adds no additional semantic context (e.g., explaining what 'workItemId' refers to or how pagination works in practice). Baseline score of 3 is appropriate as the schema handles parameter documentation adequately.

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 verb ('List') and resource ('comments for a specific work item'), making the purpose evident. It distinguishes itself from siblings like 'create_work_item_comment' or 'list_change_request_comments' by specifying 'work item' comments, though it doesn't explicitly contrast with other list tools (e.g., 'list_work_item_types').

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 on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a valid work item ID), exclusions, or comparisons with similar tools like 'search_workitems' or 'get_work_item', leaving usage context unclear.

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