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

It discloses that finalization freezes the run, that a linked repeat includes a previous frozen report while retained, and that no score/certification/judgment is produced. These are useful behavioral details beyond the sparse annotations; however, it does not explicitly warn that finalization prevents further actions.

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 short and front-loaded with the main read behavior, followed by finalization. The sentence about a linked repeat is somewhat awkward and vague, but overall every sentence contributes without excessive length.

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?

The description is adequate for a basic read/finalize tool, but without an output schema it leaves the report structure and the meaning of 'linked repeat ... while retained' vague. It also does not clarify how this differs from inspect_test_state or when finalization is irreversible.

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 100%, so the schema already documents run_id, finalize, and access_token. The description adds contextual output details but no new parameter-specific semantics, so the baseline of 3 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?

The description clearly states the tool reads a test timeline (calls, timestamps, operations, resulting state) and can optionally finalize it. It distinguishes itself through the finalization behavior, though it does not explicitly differentiate from siblings like inspect_test_state or describe_agent_test.

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 implies usage: read a test timeline, and finalize if you want to freeze the run. It does not explicitly state when to choose this over sibling tools or mention exclusions, so the guidance is present but indirect.

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