B3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only the backing endpoint (GET /process-groups/{id}) and a rough sketch of returned fields; it does not describe behavior for non-versioned groups or edge cases, so it adds modest value beyond the annotations.

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

Conciseness4/5

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

Two terse lines, front-loaded with the resource and the fields returned. It is efficient with no filler, though the endpoint note is somewhat redundant given the single-tool context.

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?

An output schema exists, so return-value exposition is not required, and the safety profile is carried by annotations. The remaining gap is the undocumented pg_id parameter and the absence of any routing guidance among sibling tools, leaving it only minimally complete.

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

Parameters2/5

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

There is exactly one parameter (pg_id, default 'root') with 0% schema description coverage, so the description carries the burden of explaining it – and it says nothing about pg_id or the 'root' default. It fails to compensate for the schema gap, though the parameter is simple and self-evident from its name.

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

Purpose4/5

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

States a specific verb+resource: it returns the 'version-control state of a process group' enumerating registry, bucket, flow, and version. This is precise enough for an agent to grasp the purpose, though it never distinguishes itself from sibling read tools like nifi_get_process_group or nifi_get_process_group_contents.

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?

The description gives no when-to-use guidance, no conditions, and no exclusions relative to the many sibling read tools. Usage is only implied by the topic ('version-control state'), leaving the agent to guess when this is preferable to nifi_get_process_group.

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