create_business_rule

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

With no annotations, the description carries full burden. It reveals important input validation quirks: condition/action expressions must include variable names directly, and boolean variables must use =0/=1. This warns of API accepting invalid forms that generate bad DS2 code. However, it does not describe permissions, rate limits, or success response, but the output schema exists.

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?

Three sentences: first states purpose, second explains container, third gives critical syntax warnings. Front-loaded with no filler, each sentence adds essential information.

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 6 required parameters with full schema coverage and an existing output schema, the description covers input quirks well. However, it lacks explanation of the return value or whether the rule is immediately effective, though the output schema presumably covers that.

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 100%, so baseline is 3. The description adds value beyond schema by clarifying that multiple conditions AND together and providing expression syntax examples (e.g., 'credit_score < 650'). This helps avoid common pitfalls.

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 'Create a new rule inside an existing SAS Business Rules rule set.' It specifies the resource (rule in a ruleset) and action (create), distinguishing it from siblings like create_business_ruleset (creates a ruleset) and update_business_rule (updates an existing rule).

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 implies usage (requires existing ruleset) but does not explicitly state when to use this tool over others (e.g., update_business_rule). No exclusions or alternatives are mentioned, leaving the agent to infer context.

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