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

With no annotations provided, the description carries the behavioral burden and does disclose two meaningful traits: credential redaction and the refusal to accept arbitrary file paths. It does not mention side effects or authorization, but 'Preview' strongly signals a read-only, non-destructive operation.

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 a single front-loaded sentence with no filler, and the safety constraint earns its place by adding critical behavioral context.

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, read-oriented tool with an output schema and self-descriptive schema property names, the description covers the core behavior and safety boundary. It falls short only in not articulating parameter semantics or explicit sibling differentiation, but those are partially recoverable from the schema and name.

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 0%, so the description needed to explain what run_id, artifact_id, limit, and offset mean, but it does not mention any of them. The word 'JSONL' and the conventional names give some indirect inference, but the description itself adds no parameter-level meaning.

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 names a specific verb ('Preview') and resource ('credential-redacted JSONL'), and adds a distinguishing constraint ('without accepting arbitrary file paths') that separates it from file-path-based alternatives among the siblings.

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?

It implies the tool is for safely previewing redacted JSONL artifacts, and the 'without accepting arbitrary file paths' clause hints at a security-driven selection criterion, but it never explicitly names when to use this tool instead of a sibling or what conditions disqualify it.

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