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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds genuinely new context beyond them: the required permission (org.compliance.manage) and the ENTERPRISE+ feature entitlement. It omits pagination or result-size behavior, so a 4 rather than 5.

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?

Three compact sentences with the core action front-loaded; the parameter hint and prerequisites follow in order of relevance. No filler or redundancy.

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, read-only list tool the description covers purpose, auth, and entitlement, which is most of what an agent needs. It does not mention result shape or pagination, though no output schema exists to carry that, leaving a small gap.

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 single parameter is fully documented in the schema, so the baseline is 3. The description's 'Filter to active-only with activeOnly=true' largely restates the schema rather than adding new semantics such as defaults or interaction with revoked exceptions.

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 names a specific verb+resource (list timesheet compliance exceptions) and scopes it to the current org, which is enough for an agent to distinguish it from list_timesheet_entries or weekly_compliance. It stops short of an explicit sibling contrast, so it is clear but not maximally differentiated.

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 the tool name and the permission/feature prerequisites ('Requires org.compliance.manage', 'Feature: auditLogs (ENTERPRISE+)') give useful gating context. However, there is no guidance on when to prefer this over related compliance tools such as weekly_compliance or list_audit_log.

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