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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds useful content about what the trail contains, but says nothing about volume, pagination, retention, or whether scopeId must be active/existing — gaps that matter for an audit-log tool.

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 front-loaded sentence with zero filler; the resource and payload contents come immediately after the verb.

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?

With no output schema, the description usefully enumerates the returned fields (validation results, timestamps, outcomes), which is exactly what the agent lacks elsewhere. It falls short only on practicalities like result volume or pagination for what may be a long audit trail.

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 coverage is 100% and the single parameter is fully documented in the schema. The description's phrase 'under this scope' only restates the parameter's role, adding no format, ownership, or validity detail beyond the schema.

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 and resource ('Get the audit trail for an execution scope') and enumerates the payload contents (tool calls, validation results, timestamps, outcomes). It is clear, but it makes no effort to distinguish itself from nearby read tools such as pcc_list_verdicts or pcc_list_requests.

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 when-to-use guidance, no prerequisites, and no named alternative. The word 'audit' hints at a post-hoc inspection context, but the agent must infer when this tool is the right choice versus other scope-related reads.

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