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 key traits: the session is 'independent', 'read-only', and 'skeptic'. However, it does not disclose the session lifecycle, whether the call is asynchronous, or what the tool returns, which matters for a 'start' style tool.

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. Every word contributes meaning: 'Start', 'independent', 'read-only', 'skeptic', and 'evidence/diff inputs' all add distinctive information.

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 tool has a complex nested task schema, no output schema, and no annotations, yet the description is only one sentence. It omits essential context such as return value, session handle, asynchronous behavior, and how to populate the nested task object, making it incomplete for an agent to invoke confidently.

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?

The description hints at 'evidence/diff inputs', which loosely maps to the task.inputs field, but it does not explain the required nested task fields such as objective, project_root, and correlation_id, nor the lane/transport parameters. With schema_description_coverage at 0%, the description fails to compensate for the schema's lack of parameter explanations.

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 a specific action ('Start'), a resource ('an independent read-only skeptic session'), and scope ('over supplied evidence/diff inputs'). It distinguishes itself through the 'skeptic' and 'read-only' qualifiers, though it does not explicitly compare against sibling tools like grok_agent_consult or grok_agent_execute.

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 the intended use case: when an independent, read-only, skeptical review of evidence or diff inputs is needed. It does not explicitly state when not to use this tool or name alternatives, so the guidance is inferred rather than explicit.

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