update_business_ruleset

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

Despite annotations already indicating destructiveHint and readOnlyHint false, the description adds specific behavioral details: changing the signature can invalidate existing rules that reference removed variables. It also recommends a pre-check via get_business_ruleset, which clarifies the potential side effects beyond generic destructiveness. This is valuable extra context that the annotations do not convey.

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 exceptionally concise, with a single purpose statement followed by a focused caution. Every sentence earns its place, and the warning is front-loaded after the purpose. There is no redundant text or unnecessary detail, making it easy to scan and comprehend.

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 mutation potential (destructiveHint true), the complex signature behavior, and the presence of a full output schema (not shown but indicated), the description covers all necessary aspects: it states the purpose, warns about risks, and advises a safeguard. The schema handles parameter details, so the description only needs to highlight the critical side-effect, which it does effectively.

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 input schema has 100% coverage for all four parameters, with detailed descriptions for each. The description does not add extra semantic meaning beyond what the schema provides; it only mentions the signature's role in invalidation, which is more behavioral than parameter-specific. Thus, the baseline score of 3 is appropriate.

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 clearly states the tool updates an existing SAS Business Rules rule set's name/description/signature, using a specific verb and resource. It distinguishes from siblings like create_business_ruleset, list_business_rulesets, and delete_business_ruleset by clearly implying modification of an existing entity.

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 description provides a contextual warning about signature changes invalidating rules and suggests checking the current ruleset with get_business_ruleset first. This offers guidance on safe usage, though it does not explicitly compare with alternatives or state when not to use it. The caution implicitly advises against blind updates, but the main usage context (updating an existing ruleset) is obvious.

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