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

Annotations already declare this as a read-only, closed-world, non-destructive operation. The description adds useful context that the output is one line per published statistic and includes period and source, but it does not describe ordering, limits, freshness, or formatting beyond that.

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-loads the core purpose before listing the content types. The bilingual repetition is mildly redundant but not confusing, and no sentence is wasted.

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 no-parameter, read-only tool without an output schema, the description gives an adequate picture of the returned content: per-signal historical results and exchange alert cases with period and source. It could be more complete by clarifying how this archive relates to the sibling signal tools.

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 input parameters, so there are no parameter semantics to clarify. The empty schema is consistent with the description, which presents this as a no-argument reference listing.

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: statistics KnockWatch has already published, including per-signal historical results and exchange alert cases with period and source. It is clear what the tool returns, but it does not explicitly distinguish itself from siblings such as recent_signals or signal_record.

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 explicit guidance on when to use this tool versus the available alternatives. The phrase 'already published' implies historical reference use, but the description does not state when-not to use it or name any sibling tool.

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