list_test_cases

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

With no annotations, the description carries the full behavioral burden. 'List all' communicates a read-only, unfiltered operation, but it does not disclose details about ordering, pagination, size limits, or whether returned entries include full test-case definitions or only references.

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, front-loaded sentence with no wasted words. 'List', 'all', 'registered', and 'test cases' are all informative and directly support agent decision-making.

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 zero-parameter listing tool, this is nearly complete: it states the resource, scope, and action. The only gap is the lack of any return-structure detail, which is somewhat mitigated by the absence of output schema and the simplicity of the operation.

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?

The tool has zero parameters, so the baseline is 4. The empty input schema and the description align; there are no parameter semantics to explain, and the description correctly adds nothing about 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 uses a specific verb 'List' and a clear resource 'registered test cases', with the scope word 'all' making it explicit. This distinguishes it from sibling listing tools like list_algorithms and list_implementations by naming the test-case resource directly.

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?

Usage is implied by the verb 'List': an agent can infer to use this when it needs all registered test cases. However, there is no explicit guidance about when not to use it or how it compares to sibling tools like register_test_case or list_algorithms.

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