post_node_configs

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

Annotations already convey that this is a non-readOnly, non-idempotent, open-world write, and the description adds no behavioral context beyond restating 'update.' It does not disclose whether configs replaces the entire configuration set or merges with existing entries, nor whether changes apply immediately or require a restart.

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?

The description is a single six-word sentence with the verb front-loaded and zero filler. It is efficient and scannable, though the terseness borders on under-specification.

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 three-parameter tool with a fully documented schema and safety annotations, the core essentials are present. However, it omits useful operational context: what the response looks like (no output schema), how configs are applied (merge vs. replace), and that get_node_configs is the read counterpart.

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%, with nodeId, cluster, and configs each described, so the baseline of 3 applies. The description contributes nothing beyond the schema — it provides no extra meaning about how the configs array is interpreted (e.g., full replacement vs. patch).

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 uses a specific verb ('Update') and a specific resource ('configuration for a node'), making the operation immediately clear. It is distinguishable from read siblings like get_node_configs by the verb, but it never names that alternative explicitly, so it stops short of full sibling differentiation.

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?

No guidance is given about when to use this tool versus get_node_configs (to read current values) or post_topic_configs/post_connect_configs (similar tools for other resource types). There are no prerequisites, conditions, or exclusions stated; the agent must infer usage entirely from the tool name and schema.

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