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

No annotations are provided, so the description carries the full burden. It does meaningful work by disclosing the returned securitySummary shape and warning that isSecureVersion/statusLabel describe lifecycle only, so a supported version may still have open bulletins — a genuine misinterpretation trap. It omits read-only confirmation, auth needs, ordering, and pagination.

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?

Front-loaded with the core purpose, then two dense but purposeful sentences covering return shape and cross-tool routing. The second sentence is syntactically heavy but every clause carries information an agent needs.

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, the description usefully explains the key returned fields and their interpretation, and it points to check_version_security for remedies. The remaining gap is the undocumented distribution parameter, which leaves the agent guessing at filtering semantics.

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% for the single required 'distribution' parameter, so the description must compensate and it does not mention the parameter at all. The enum values are self-descriptive, which softens the gap, but the description adds nothing about what distribution filters or what values are accepted.

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 and resource with a scope qualifier ('versions that have reached end-of-life') that cleanly separates it from siblings like get_supported_versions and get_all_versions. An agent can select this tool without opening the schema.

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?

It routes the agent onward ('Call check_version_security for the remedies') and implies this tool is for lifecycle/support questions, but it never states when to use this tool versus get_supported_versions or get_all_versions. Usage is implied rather than explicit.

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