Verify Audit Chain

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

Annotations already cover readOnlyHint=false and destructiveHint=false, so the safety profile is known. The description adds useful context about the cryptographic verification method (SHA-256) and the goal (non-repudiable tamper resistance), but it does not clarify whether verification has side effects (e.g., writing a verification report) or how failures are handled, given readOnlyHint=false.

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 a single concise sentence that front-loads the action and resource, with no redundant words. Every part adds value.

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 simple (one optional parameter), and annotations cover safety aspects. However, there is no output schema, and the description does not specify what the verification returns (e.g., boolean, report) or error behavior, leaving a gap for an agent deciding whether to invoke the tool.

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 schema has one optional parameter 'project' with a clear description, achieving 100% schema description coverage. The tool description adds no parameter-specific details, which is acceptable because the schema already explains the parameter.

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 clearly states the tool's function with a specific verb ('verify'), the resource ('cryptographic SHA-256 event audit chain'), and the purpose ('non-repudiable tamper resistance'). This distinguishes it from sibling tools like audit_project_db or get_event_log, which focus on different audit aspects.

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 description implies the tool is for checking audit chain integrity, providing clear context for when to use it. However, it does not explicitly mention when not to use it or name alternatives, such as using get_event_log for reviewing events or audit_project_db for a database-level audit.

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