Verify Audit Integrity

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly explains the mechanism (SHA-256 hash chain), what it detects (modified, added, or removed entries), and the outcome ('detect the break point'). It also states the access policy ('All roles can verify'). This is strong transparency for a read-only verification tool, though it does not explicitly state whether it returns a simple pass/fail or detailed report.

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 extremely concise: two sentences, front-loaded with the verb and resource, and each sentence adds meaningful information. There is no fluff or repetition of the title/name.

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 simple, no-parameter tool with no output schema, the description covers what it does, how it works, and who can use it. It might be slightly more complete if it mentioned the return format or edge cases, but given the tool's simplicity, the description is adequately complete.

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 the schema shows no properties. Per the scoring rules, a baseline of 4 is appropriate when no parameters exist. The description adds no parameter-level detail because none is needed; the schema already has 100% coverage.

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 uses a specific verb 'Verify' with a clear resource ('audit trail') and method ('checking the SHA-256 hash chain'). It clearly distinguishes itself from sibling tools like cleanroom_audit_log and cleanroom_audit_export, making its purpose unambiguous.

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?

The statement 'All roles can verify the audit trail' provides clear context about when the tool can be used, implying it is appropriate for any user without special permissions. It does not explicitly mention alternatives, but for a verification tool with no parameters, the context is sufficient to infer its role relative to siblings.

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