ado_create_pull_request_thread

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

With no annotations, the description must fully disclose behavioral traits. It only states that the tool creates a thread, but omits details like authentication requirements, side effects on pull requests, or whether the operation is reversible. This is insufficient for an agent to understand the tool's impact.

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 front-loads the key information. Every word is necessary, and there is no redundancy.

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?

Although the schema provides good parameter documentation, the description lacks essential context such as return value structure, error conditions, or how the thread relates to pull request workflows. This is a creation tool with multiple parameters, and a more comprehensive description would enhance usability.

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%, so the baseline is 3. The description adds no meaning beyond the schema, merely repeating that it can be a general or code comment. No additional context is provided for the parameters.

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's purpose: creating a new comment thread, and distinguishes between general and code comments. It uses a specific verb ('Crea') and resource ('hilo de comentarios'), which effectively differentiates it from sibling tools like ado_add_comment or ado_reply_to_pull_request_thread.

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 explicit guidance is provided on when to use this tool versus alternatives such as ado_add_comment or ado_reply_to_pull_request_thread. The description hints at two use cases (general vs. code comments) but does not explain prerequisites or context for selection.

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