Update Business Rule

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds nothing beyond that: it never says the call replaces the whole rule definition (all 7 params are required), nor mentions locking, revision creation, or validation side effects that matter for a destructive update.

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?

One tight sentence with no filler and the resource is front-loaded. It is efficient, though the brevity contributes to the missing-behavior gaps noted elsewhere.

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 destructive, 7-required-parameter update inside a locked-revision workflow, the description omits the full-replacement semantics and the locking/prerequisite step. An output schema exists so return values need no explanation, but the operational context an agent needs to call this correctly is absent.

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 the schema already explains each parameter (rule UUID, ruleset UUID not name, conditional semantics, condition/action lists). The description adds no parameter-level meaning beyond that, which is the baseline 3 case.

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?

States a specific verb and resource ('Update an existing rule inside a SAS Business Rules rule set'), which is clear enough to distinguish it from create_business_rule and update_business_ruleset by resource granularity. It does not explicitly contrast with those siblings, but the resource is unambiguous.

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 guidance on when to choose this over update_business_ruleset or create_business_rule, and no prerequisites are mentioned — notably that a rule set revision likely must be locked first (siblings lock_business_ruleset_revision / lock_decisioning_asset_revision exist). The agent must infer all of this.

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