list_work_item_comments

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: no pagination behavior, no ordering, no indication of whether all comments or a truncated set are returned. For a list operation with openWorldHint, some note on scope or volume would have real value.

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?

One short sentence with zero filler, which is efficient, but it borders on under-specification rather than true conciseness. Nothing is front-loaded because there is nothing else to front-load.

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 single-parameter read tool whose annotations cover safety and whose schema covers the input, this is minimally sufficient. It is still thin on what the agent gets back (and with no output schema, the return shape is entirely undisclosed) and on behavior for large comment lists.

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 coverage is 100% and the single parameter is documented as a work item UUID, so the schema carries the load. The description's phrase "of a work item" is consistent with that but adds no new meaning such as whether the id can be a short form or a display key.

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 pairs a specific verb ("List") with a specific resource ("comments") and scope ("of a work item"), so an agent can tell it retrieves comments rather than mutating them. It stops short of naming how it differs from siblings like list_work_items or create_work_item_comment, but the verb+resource is unambiguous.

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 when-to-use guidance, no prerequisites (does the work item need to exist / be accessible?), and no mention of what alternative to pick if you want comments across multiple items or a single comment. The agent must infer all of this from the tool name alone.

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