Recent generations

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

Annotations already declare readOnlyHint=true, so safety is covered. Beyond that the description discloses nothing: no ordering rule for 'recent', no default limit behavior, no pagination or truncation semantics, which matters for a 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?

It is a single short sentence with no wasted words, but the brevity reflects under-specification rather than discipline. It is front-loaded in the trivial sense that there is only one clause.

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 low-complexity, read-only, single-optional-parameter tool the bar is modest, but the description adds nothing about the limit semantics, ordering, or what a 'generation' record contains. An agent gets no help deciding how to call it correctly.

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 0% and the single 'limit' parameter (default 10, max 100) is undocumented in both schema and description. The description does not compensate for this gap by explaining the limit, its bounds, or the default page size.

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 sentence 'The user's recent API generations.' is a noun phrase that essentially restates the title 'Recent generations' without naming an action verb. It conveys the resource and that a list is implied, but it does not distinguish itself from siblings like get_generation or list_generators.

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 mention of the single-generation alternative (get_generation), and no exclusions. The word 'recent' hints at scope but provides no actionable selection criteria.

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