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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed world, so the safety profile is fully covered without the description. The description only adds the 'all modules' scope and 'dated' framing, which is modest extra context for a read 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?

A single compact sentence that front-loads the resource and scope with no filler. It is efficient, though the fragmentary phrasing leaves the operation implicit rather than stated.

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 read tool with no output schema and annotations covering safety, the description is just barely adequate: it does not say what an entry contains, how results are ordered, or how this log relates to get_evidence_bundle or the module-scoped tools. Nothing is wrong, but it is thin.

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, so there is nothing for the description to disambiguate; the schema correctly declares an empty object with additionalProperties false. Baseline 4 applies since parameter semantics are a non-issue here.

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 the resource ('evidence-review log') and its scope ('for all modules'), and 'Dated' hints at ordering. However, it is a bare noun phrase with no verb, so the action (retrieve/list) is only implied, and it does nothing to separate it from near-siblings like get_evidence_bundle or get_claims.

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 when-to-use guidance, no mention of when this log is preferable to get_evidence_bundle, and no prerequisites. The scope qualifier 'for all modules' weakly implies it is the global variant versus per-module siblings, but that must be inferred.

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