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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only names the content ('min score and session window') but does not say whether this is a static reference, a computed summary, or how the values relate to alert generation. With zero annotation coverage and no behavioral detail, this is a significant gap.

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 concise sentence that front-loads the core resource ('Pro alert criteria') and immediately specifies the two key pieces of information. It contains no padding, repetition, or irrelevant detail.

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 zero-parameter tool with an output schema present, the description is largely complete: it tells an agent what topic the output covers. The main shortfall is the lack of any contextual framing about how 'min score' and 'session window' relate to the pro alert system, but the output schema can carry the detailed return structure.

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 has zero parameters and schema description coverage is 100%, so the schema fully documents the input surface. The description adds meaning about what the output covers, which is appropriate. The baseline for 0-parameter tools is 4, and nothing here reduces that.

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 states a specific resource ('Pro alert criteria') and the key content ('min score and session window'), which is distinct from the sibling tools that retrieve live alerts or check tradeability. However, it lacks an explicit verb like 'returns' or 'summarizes', so the action is implied rather than stated.

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?

There is no guidance on when to use this tool versus alternatives such as get_latest_alert or check_alert_tradeable. The description implies this tool provides criteria definitions, but it does not state a use case, prerequisites, or exclusions.

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