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

With no annotations, the description carries the full burden. It discloses that the operation is read-only in nature and that the check pack is public, and it notes that the result includes available versions. However, it does not cover rate limits, authentication requirements, error behavior, or output shape in detail.

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 or redundancy. Every phrase contributes to identifying the resource and the operation.

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 simple read tool with no output schema and no annotations, the description is minimally adequate: it identifies the main resource and mentions version listing. It remains thin on slug semantics, output structure, and operational constraints, which leaves gaps given the missing structured coverage.

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 only 50%: check_pack_version is documented in the schema, but check_pack_slug has no description there. The tool description does not compensate by explaining the slug's format, origin, or semantics, so parameter meaning remains incomplete.

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 states a specific verb and resource: 'Read one public check pack version and the list of available versions.' It distinguishes reading a single version from a broader pack list, though it does not explicitly name or differentiate against sibling tools such as check_packs_list.

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 explicit guidance on when to use this tool versus alternatives, nor any stated preconditions or exclusions. The read-oriented phrasing implies a retrieval use case, but the agent must infer that context.

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