verify_event_log

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

The description discloses the core mechanism—replaying the log and comparing it—which implies a read-only integrity check. However, with no annotations provided, it leaves unstated what happens on mismatch, what the return value is, and whether any state is written.

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 clear sentence, front-loaded with the action verb and containing no filler. Every word contributes to understanding the operation.

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 is low-complexity with no parameters and no output schema, so the description is usable. Still, without annotations or output schema, an agent is left guessing about the result format and whether this verification has side effects or should be run under specific conditions.

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 there is nothing for the description to add. The baseline of 4 applies because parameter semantics are fully trivially satisfied.

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 verb ('Replay'), the exact resource ('append-only event log'), and the comparison target ('stored snapshot'). None of the sibling tools overlap with this operation, so an agent can clearly distinguish it.

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 run this tool, what prerequisites might exist, or what alternatives should be considered. An agent would have to infer from the name that this is an integrity-check operation.

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