update_td_node_parameters

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

Annotations indicate readOnlyHint=false, destructiveHint=false, so mutating but not destructive. The description adds valuable behavioral details: return structure {path, updated, failed: [{name, reason}], message}, and that unknown names go to failed rather than raising an error. This clarifies error handling beyond annotations.

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 two sentences: first sentence states purpose, second explains return value and behavior. It is front-loaded and contains no superfluous text. Every sentence adds value.

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?

Given the presence of an output schema and annotations covering safety, the description is fairly complete. It explains the return structure, failure mode, and hints at prerequisite verification. It effectively sets expectations for the tool's behavior.

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%; all parameters have descriptions. The description adds only minimal parameter-related info (failure mode). Baseline is 3, and the description does not significantly enhance parameter understanding beyond the schema.

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 clearly states 'Set parameter values on an operator.' The verb 'set' and resource 'parameter values on an operator' are specific. This distinguishes from sibling tools like get_td_node_parameters (read) and other manipulation tools.

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?

The description implies usage by stating 'Verify names first with get_td_node_parameters' but does not explicitly state when to use or not use this tool, nor does it provide alternatives. It offers a hint but lacks comprehensive usage guidance.

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