List models retiring soon

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

Annotations already indicate read-only and open-world hints. Description adds the sorting order ('soonest first'), which is useful but minor. No mention of pagination, rate limits, or other behaviors beyond what annotations imply.

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 sentences that are efficient and front-loaded. First sentence states the core function and sort order; second sentence adds practical usage context. No superfluous words.

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?

Given the low complexity, full schema coverage, and read-only annotations, the description is mostly complete. It lacks details on return format or error handling, but these are acceptable omissions for a simple list 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% (both parameters documented). The tool description does not add any additional meaning or context about the parameters beyond their schema definitions, so baseline score 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?

Description clearly states the tool lists retiring models with a time window and sort order. It doesn't explicitly compare to siblings, but 'audit a codebase or plan migration work' provides context that distinguishes from general search tools.

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?

Explicitly says 'Use this to audit a codebase or plan migration work,' providing clear use cases. However, no mention of when not to use or alternatives like 'recent_lifecycle_changes' or 'check_model'.

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