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

The annotations already convey that this is not read-only, likely has open-world effects, and is marked destructive, so the description is not the sole signal. However, the description adds no context beyond annotations—it does not explain what side effects replying to a comment has or why the destructive hint is set.

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 short, but it is under-specified rather than genuinely concise. It spends its single sentence saying exactly what the tool name and title already say, adding no structural or scoped information.

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?

Given that the tool has 8 parameters, platform-specific details, and a rich schema, the description should orient the agent to when and why this tool is the right one. The schema covers the parameter details, but the description's failure to provide any kind of behavioral context leaves the overall definition incomplete for an agent.

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 each of the 8 parameters is already individually documented in the input schema. The description adds no further parameter-level meaning, but the schema does the necessary work, keeping this at the baseline.

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?

Tautological: description restates name/title.

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 explanation of when to use this tool versus alternative comment or reply tools. The intended usage is only implied by the tool name and title, with no mention of exclusions, prerequisites, or alternative choices.

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