test_cases_attachments_update

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

With no annotations, the description must fully disclose behavior. It only states the action (mark as uploaded) but omits side effects, prerequisites, idempotency, or error conditions. This is insufficient for an agent to understand the full 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 short (two sentences) and front-loads the core purpose. The 'Tag: Test Case Attachments' line is redundant but not harmful. Could be slightly cleaner by removing the Portuguese duplication, but overall efficient.

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 mutation tool with no output schema or annotations, the description lacks completeness. Missing details on when the upload is confirmed, error scenarios, and whether it can be called multiple times. The Portuguese hint about 'após o PUT no S3' adds some context but is not explicit.

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%, providing 'Test Case ID' and 'Attachment ID'. The description adds no further parameter details beyond the context of confirming an upload. Baseline of 3 is appropriate as the schema already documents 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: 'Confirm test case attachment upload' and sets 'uploaded=true'. It uses a specific verb (update/confirm) and resource (test case attachment), and the sibling tools show it is distinct from other attachments_update tools for different entities.

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 usage after an S3 PUT ('após o PUT no S3'), but does not explicitly state when to use this tool over alternatives, nor provide when-not-to-use guidance. No comparison with sibling tools is given.

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