set-flows-state

Update the deployment state of all flows in a Node-RED instance by providing a JSON object describing the desired flows state.

Updates the deployment state of all flows in the Node-RED instance.

Behavior2/5

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

With no annotations, the description must disclose behavioral traits. It only states 'updates the deployment state' but fails to explain side effects (e.g., whether flows restart, if the change is immediate, idempotency, or required permissions). The description is too brief for a potentially impactful write operation.

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?

The description is a single sentence, which is concise and front-loaded with the verb and resource. However, for a potentially complex operation, it may be too terse; still, it avoids unnecessary words.

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

Completeness2/5

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

Given one parameter with full schema coverage but no output schema, the description lacks essential context: what constitutes 'deployment state', how to structure stateJson, and what success/failure looks like. The minimal description fails to equip the agent for correct invocation.

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?

The input schema describes the single parameter 'stateJson' as 'Flows state in JSON' with 100% coverage. The description adds no extra meaning beyond what is already in the schema, 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 clearly states the verb 'updates' and the resource 'deployment state of all flows', effectively distinguishing it from siblings like 'update-flow' which targets individual flows. The phrase 'all flows' removes ambiguity.

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 guidance is provided on when to use this tool versus alternatives such as 'update-flows' or 'get-flows-state'. There is no mention of prerequisites, scenarios, or exclusions, leaving the agent to infer usage from the name alone.

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