build_uploads__build_upload_files__list

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

Annotations already mark the tool as readOnly and non-destructive. The description adds no extra behavioral context beyond the endpoint path. It does not describe pagination behavior, ordering, or other side effects. Since annotations cover safety, a score of 3 is appropriate.

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 concise: one sentence plus the HTTP path. It is front-loaded with the action. However, it could be more informative by including a brief hint about pagination or output structure without being verbose.

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 the lack of an output schema, the description should at least mention that the response contains a list of build upload file objects. It does not. The parameters are well-documented, but the tool's output remains unspecified, leaving some ambiguity for an AI 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?

Input schema has 100% description coverage for all 3 parameters. The description adds minimal extra meaning, just relating the 'id' parameter to 'a build upload'. No additional parameter details are provided beyond the schema. Baseline 3 is correct.

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 'List the build upload files belonging to a build upload', which is a specific verb and resource. It includes the HTTP method and path, making the action unambiguous. It distinguishes from sibling tools like build_upload_files__get (single file) and build_upload_files__create (creation).

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 implies the tool is used to list files for a specific build upload, but it does not provide explicit guidelines on when to use this vs alternatives, nor does it mention prerequisites or when not to use it. The sibling list is extensive, but the description offers no comparative guidance.

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