create_commit_comment

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It gives no information about side effects, required permissions, rate limits, or what happens on successful creation. The 'create' verb implies a mutation but does not specify any consequences or return behavior, which is a significant gap.

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 concise sentence that is entirely front-loaded. It avoids any filler or repetition, achieving maximum efficiency. Every word adds value, making it an exemplar of conciseness.

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 has four required parameters and no output schema, yet the description offers nothing about return values, error conditions, or typical scenarios. It is a simple create action, but the lack of any behavioral context or usage examples leaves the agent without enough information to fully understand execution. Given the minimal description and absent annotations, this is insufficient.

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%, with each parameter having a description (in Chinese), so the baseline is 3. The tool description itself adds no parameter information; it only restates the action. Since the schema already covers the parameters, the description does not need to add more, but it also doesn't provide any usage nuances beyond the schema.

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 states 'Create a comment on a commit', which is a clear verb+resource pairing. It distinguishes this tool from sibling tools like create_change_request_comment and create_work_item_comment by specifying the target as a commit. It is specific but lacks any additional context about the commit scope (e.g., whether it's a review comment or general).

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 provides no guidance on when to use this tool versus alternatives. It simply states the action without any context about prerequisites, typical use cases, or exclusions. Among sibling comment-creation tools, there is no differentiation in usage context, leaving the agent to infer from the name alone.

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