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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds only the vague word 'recent' — it doesn't define the recency window, ordering, pagination behavior, or that customerId requires superadmin rights. With annotations carrying the safety load, this adds very little.

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. It is efficient, though the extreme brevity is under-specification rather than disciplined conciseness.

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?

Minimum viable: schema documents all parameters and annotations cover the read-only safety profile, with no output schema to explain. However, the undefined 'recent' window and absent tie-breaking to sibling list/detail tools leave real gaps for the agent.

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%, with all three parameters documented including the status enum and the superadmin-only note on customerId. The description adds no parameter meaning beyond that, so the baseline 3 applies — the schema does all the work.

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 (optimization runs) with a scoping qualifier ('recent'). It is clear what the tool returns, but it does nothing to distinguish itself from siblings like get_optimization_details, list_optimization_feedback, or get_model_optimization_status.

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 guidance on when to call this versus get_optimization_details, list_optimization_feedback, or get_model_optimization_status. No mention of prerequisites or when the result set is appropriate, so the agent must infer usage 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.
