get_business_ruleset

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

There are no annotations provided, so the description must carry the full burden. It states 'Fetch' which implies a read-only operation, but it does not disclose any behavioral traits such as whether the tool fails for invalid IDs, whether it returns only metadata or includes rules, or any permission requirements. This is minimal disclosure for an unannotated 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?

The description is a single concise sentence that front-loads the action ('Fetch') and specifies the resource and lookup method. There is no wasted wording or redundant detail.

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?

Given the tool's low complexity (one parameter, output schema exists), the description is mostly sufficient. It doesn't explain the return value, but the output schema is provided so that is not required. However, a brief note about not-found behavior or the ID source would make it more complete; still, for a simple fetch tool, this is adequate.

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?

The schema is 100% covered with a clear parameter description ('The rule set UUID (not its name — list_business_rulesets returns both)'), so the baseline is 3. The tool description itself adds no parameter-specific info beyond the schema, but it doesn't need to because the schema is already effective.

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 uses the specific verb 'Fetch' and identifies the resource as 'a single SAS Business Rules rule set' with the method 'by ID'. This clearly distinguishes it from sibling tools like list_business_rulesets (which lists all) and delete_business_ruleset (which removes).

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?

The usage is implied: 'by ID' indicates you need a specific ruleset_id, likely obtained from list_business_rulesets. However, there is no explicit statement about when to use this tool versus alternatives or that list_business_rulesets is the way to discover the ID. The guidance is inferable but not stated.

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