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

Annotations already establish readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that it recomputes *every* hash (suggesting a full scan rather than a sampled check) and reports the latest checkpoint, which is useful context beyond the annotations, but it omits cost, failure/mismatch behavior, and what a passing vs failing result looks like.

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?

One sentence with no padding, and the core action ('recompute every hash') leads. Every clause carries information.

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?

An output schema exists, so return values need not be explained, and annotations cover safety and locality. The remaining gap is behavioral: what happens on a hash mismatch and whether the on-chain checkpoint lookup can be unavailable, which the description leaves silent.

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, which is the baseline-4 case; there is nothing for the description to disambiguate. The absence of parameters is consistent with a full-log verification.

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?

States a specific verb pair (recompute hashes, show checkpoint) against a specific resource (the call log), which is clearly distinct from the sibling call_log that just returns entries. It stops short of explicitly naming that sibling, so an agent must infer the distinction.

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?

Usage is implied by 'verify' — an agent should call this when it wants integrity confirmation rather than raw log data — but there is no explicit when-to-use, when-not-to-use, or named alternative. Nothing tells the agent whether this is a cheap check or what to do if verification fails.

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