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

No annotations are provided, so the description carries the full burden, and it does meaningful work: it declares the non-streaming, one-shot snapshot behavior ('without streaming'), which is the key trait distinguishing it from stream_test, and names the returned fields. It stops short of disclosing error/not-found behavior, retention of results, or polling cost, so it is strong but not exhaustive.

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, zero filler, front-loaded with the purpose and return contents before the routing advice. Every clause earns its place.

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?

With no output schema and no annotations, the description compensates by enumerating the returned fields (status, verdict, generated test content), so an agent knows what to expect. It omits failure modes (invalid/stale testId) and whether the read is cheap to poll repeatedly, which are the remaining gaps.

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?

Only one parameter (testId) and schema description coverage is 100%, with the schema itself explaining that it comes from test_component. The description adds only 'by ID', so the baseline 3 for a schema-complete single parameter is appropriate.

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 (get), resource (test), keying mechanism (by ID), and enumerates what it returns: status, pass/fail verdict, generated verification test content. It also explicitly distinguishes itself from the sibling stream_test, so an agent can pick between them without opening either schema.

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?

Gives both a positive condition ('useful for polling or inspecting a test after the fact') and an explicit alternative with the condition that selects it ('Use stream_test to follow a test in real time instead'). This is the when/when-not/alternative pattern done fully.

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