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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds value by naming the returned fields (trace ID, group, version, status, match result, latency), but says nothing about ordering, pagination behavior, or result volume, which matter for an 8-param list 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?

Two short sentences with the purpose front-loaded and no wasted words. It is efficient, though the second sentence reads more like a field inventory than decision-relevant guidance.

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 present, the description usefully enumerates the returned fields, and readOnlyHint covers safety; the fully-described schema covers inputs. The main gap is the lack of differentiation from sibling history tools, but the definition is broadly complete for calling 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?

Schema description coverage is 100%, so all 8 parameters (including enum status and the time-zone-aware date fields) are already documented in the schema. The description adds no parameter-level detail beyond echoing the field names, so the baseline of 3 applies.

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 (List) and resource (policy execution history), so the core intent is clear. However, it does not distinguish itself from the closely-related siblings lexq_history_get and lexq_history_stats, which an agent would need to tell apart.

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 gives no guidance on when to use this versus lexq_history_get (single record) or lexq_history_stats (aggregated), nor any prerequisites or filtering context. Usage must be inferred from the name alone.

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