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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and openWorldHint=false, so the safety profile is fully covered. The description adds nothing on top of that — no indication of cost, caching, or whether the scope can change between calls.

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?

A single short, front-loaded sentence with no filler or redundancy. It is efficient but only because it omits content rather than because it is well-structured.

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?

There is no output schema and no parameters, so the description carries the entire burden of explaining what a caller receives and what 'scope' means in this domain. It delivers none of that, leaving the agent unable to judge whether the response is worth a call.

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 tool takes zero parameters, and the input schema is empty with full coverage, so there is nothing for the description to clarify. Baseline 4 applies; no parameter-level information is missing.

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 sentence restates the title almost verbatim ('Get research scope' → 'Get information about the current research scope') without saying what 'research scope' contains or what kind of information is returned. It is generic enough that an agent cannot distinguish it from get_context or get_signals on the basis of the description alone.

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?

No when-to-use condition, no exclusions, and no mention of the obvious sibling expand_research_scope, which is the mutating counterpart to this read. The agent is left to infer the intended trigger from the name.

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