link_autotest_to_case

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

Even with annotations present, the description adds substantial behavior context: the link is forward-only, historical results are not backfilled, and the returned testExists/wasCreated fields do not mean history was attached. It also explains the concrete get_test_case side effect with an empty includeRecentExecutions until the next report, which is genuinely useful.

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 dense but every sentence earns its place: the core action is first, followed by the forward-only warning, the meaning of the return fields, and the relevant alternative tool. There is no filler or redundant repetition.

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 two-parameter tool with no output schema, the description gives the agent what it needs: the side-effect model, the return-field semantics, the important no-backfill behavior, and a pointer to get_test_history for existing results. No critical operational gap remains.

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 input schema already covers both parameters with descriptions and 100% coverage, so the baseline applies: the description does not add much new parameter-specific format or syntax detail. It reinforces that linking happens testTitle and can be for an autotest that does not exist, but those are behavioral clarifications rather than parameter semantics.

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 opens with a specific verb and resource: 'Link an automated test, by title, to a manual test case for coverage tracking.' This clearly distinguishes it from sibling linking tools like link_launches_to_release and add_external_link, and makes the exact entity relationship explicit.

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 gives explicit when-to-use context: it supports pre-linking since the autotest does not need to exist yet. It also warns that the link is forward-only and no past results are backfilled, and directs agents to 'Use get_test_history to read the results that already exist for that title,' which is a clear alternative.

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