list_decision_flow_revisions

List all locked revisions for a decision flow by providing its UUID. Enables auditing of workflow version history in SAS Viya.

Instructions

List all locked revisions of a decision flow.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
limitNoMaximum number of results to return (default 20).
decision_idYesThe decision flow UUID (not its name — list_decision_flows returns both).

Behavior3/5

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

With no annotations, the description carries the safety burden. The verb 'list' implies read-only, and the scope is clear (locked revisions), but it does not explicitly state that it has no side effects, nor does it clarify what 'locked' means or mention ordering/pagination behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, direct sentence that front-loads the verb and object. No wasted words, perfect conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with a full output schema, the description is adequate but minimal. It lacks context on what qualifies as a 'locked' revision and any limitations on the results (e.g., pagination, sort order), which would help the agent use it more effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and both parameters have detailed descriptions (e.g., decision_id is a UUID, limit has a default). The tool description adds no additional parameter meaning, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') and resource ('locked revisions of a decision flow'), clearly distinguishing it from siblings like get_decision_flow_revision (single revision) and list_decision_flows (flows, not revisions).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidance is provided. It does not mention when to use this tool versus alternatives, nor any prerequisites or exclusions, leaving the agent to infer from the tool name alone.

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