test_client_status

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

With no annotations, the description carries the full disclosure burden. It discloses that the pid check is conditional ('if given') and that the port check is a connectability test, which is genuinely useful behavioral detail. However, it never states that the operation is read-only/side-effect-free, nor any auth or timeout behavior, so the safety profile is only implied by 'Report'.

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 tight sentences that front-load the purpose and follow with the usage window. No filler or redundancy.

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?

An output schema exists, so return-value explanation is not needed, and the description covers purpose and placement in the workflow adequately for a simple diagnostic. The only gap is that the optional pid and default host/port semantics are left partly to the schema, which is bare.

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 coverage is 0%, so the description must compensate. It clarifies that pid is optional ('if given') and that host:port refers to the TPort endpoint, which adds meaning beyond the bare schema. It does not explain the defaults (127.0.0.1, 15381) or the null default for pid, leaving some parameter semantics undocumented.

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 ('Report') and resource ('a launched TestClient's health'), then enumerates the two exact checks performed (pid alive, TPort listening/connectable). An agent can readily distinguish this diagnostic from siblings like launch_test_client, stop_test_client, and get_test_results.

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?

Explicitly positions the tool in the workflow: 'Use after launch_test_client / before driving a scenario,' naming the preceding sibling. It gives clear usage context but no exclusion rules (e.g., when not to bother, or what to do if the check fails).

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