get_test_run_users

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=true, so the safety profile is covered by structured data. The description adds no behavioral context beyond restating that it reads users; it does not mention pagination, ordering, or what happens when the test run has no users.

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?

Two sentences, but the second is largely a restatement of the first ('get all users for a test run' vs 'retrieve all users assigned to a specific test run'). It is short but not maximally front-loaded or information-dense.

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 simple single-parameter read tool with full annotation coverage and no output schema, the description is minimally adequate: it identifies the resource and the required identifier. It lacks ordering/pagination context but nothing critical is missing to invoke it correctly.

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 reported at 0%, so the description should compensate, but it only repeats that the identifier is 'unique' without adding format, type, or constraint detail. The nested path.testRunId schema does carry a minimal inline description, so the description contributes essentially nothing new.

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?

States a specific verb and resource: retrieve all users assigned to a test run. It is clearly distinguishable from nearby siblings like get_test_run_test_cases or get_team_members, though it does not explicitly call out that distinction.

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?

There is no guidance on when to use this tool versus alternatives (e.g., get_user_collection or get_team_members), nor any prerequisites or context about when a test-run user listing is appropriate. Usage must be inferred entirely from the name.

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