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

With no annotations provided, the description bears full responsibility for behavioral disclosure. While it mentions 'cache' as a side effect, it fails to explain cache duration, location, invalidation behavior, or what specific data is returned (binaries, metadata, checksums?). No error conditions or rate limit warnings are mentioned.

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?

Single sentence, front-loaded with action verbs, zero redundancy. Every word serves a purpose despite the sentence being information-dense.

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?

Lacking an output schema, the description should describe return values, but only uses the vague term 'information'. Missing details on cache persistence, error formats, and what specific Terraform data is retrieved (release notes, assets, tags).

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 coverage is 100% with the 'version' parameter fully documented in the schema including examples. The description adds no additional parameter semantics, meeting the baseline score for high schema coverage.

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 provides specific verbs ('Fetch and cache'), identifies the resource ('Terraform versions'), and specifies the source ('GitHub releases'). It distinguishes from siblings (ansible, docker, go, etc.) by explicitly naming Terraform, though 'information' is slightly generic.

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 explicit guidance on when to use this tool versus alternatives (e.g., direct GitHub API calls), nor does it explain when the cache is used versus fresh fetches. The description does not indicate prerequisites or conditions for invocation.

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