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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the 'public approved' scope, which is meaningful behavioral context about visibility/approval, but it does not disclose error behavior or locale effects.

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?

The description is a single front-loaded sentence with no filler; every word contributes to the basic meaning. It is efficient, though it sacrifices detail that would improve usability.

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?

This is a simple read-only tool with rich annotations, but the description omits the optional locale's role, how stack IDs are discovered, and any return-format information given the absence of an output schema. It is minimally adequate but leaves notable gaps.

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%, so the description must compensate, but it only references 'stack' without explaining that id is the stack UUID or what the locale parameter controls. The schema's type and enum provide structure but not semantic meaning, leaving locale unexplained.

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 description names a specific verb ('Get'), resource ('stack'), and qualifier ('public approved'), making the core operation clear. It distinguishes from get_guide and get_tool by resource, though it does not explicitly differentiate itself from sibling list_stacks beyond singular versus plural phrasing.

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?

No guidance is given on when to use get_stack versus alternatives like list_stacks or search_tools. The description does not mention prerequisites or discovery flows, such as obtaining a stack ID via list_stacks.

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