Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of behavioral disclosure. It does disclose that the tool returns chain status and broken links, which is valuable, but it does not mention whether the operation is read-only, if there are side effects, or how failures are reported.
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 two concise sentences with no filler. The core action is front-loaded, and the return behavior is stated immediately after, making it easy to scan.
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 single-parameter tool with no output schema, the description gives the essential purpose and return information. It is slightly incomplete on when to choose this over sibling tools, but the overall definition is sufficient for basic invocation.
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?
Schema description coverage is 100%, and the only parameter, logPath, is already described in the schema as 'Path to the audit log file (JSONL)'. The tool description adds no additional parameter-level detail, so the schema provides the necessary semantics.
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 integrity') with a clear resource ('MCP audit log') and states the outcome ('Returns chain status and any broken links'). It clearly distinguishes this from sibling tools like audit_tail and audit_status, which have different operational purposes.
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?
No explicit guidance is provided on when to use this tool versus audit_tail or audit_status. The description only states what the tool does, leaving the agent to infer the appropriate selection context without any exclusions or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
