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

Annotations already declare the basic profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=true), so the bar is lower. The description adds the genuine workflow dependency on get_deployment_options and the Global-only constraint. It omits meaningful behavior for an open-world, non-idempotent provisioning call: whether it is billable, how long provisioning takes, and whether a duplicate call creates a second node.

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?

It is short and front-loads the action, but the get_deployment_options prerequisite is stated twice in near-identical form, and the parenthetical about node_tier "Global" introduces an attribute not present in the schema, adding confusion rather than precision.

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?

With a full output schema and 100% parameter coverage, the description only needs to cover workflow and validity constraints, which it does. Missing only the cost/provisioning-time framing that an agent weighing a paid, non-idempotent deployment would benefit from.

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%, so every parameter already carries its own description including the ID formats. The description's "Global option" note mirrors what the cloud parameter description already says, so it adds little beyond the schema. It also references a "node_tier" concept that does not exist as a parameter.

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?

"Deploy a new blockchain node" gives a specific verb and resource, which cleanly separates it from delete_node, update_node, get_node and list_nodes in the sibling set. It does not, however, explicitly state the create-vs-update boundary in words.

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?

It gives an explicit prerequisite ordering ("Call get_deployment_options first for valid IDs") and a constraint on which option class to pick (a Global option). There is no exclusion guidance — e.g. "use update_node to modify an existing node" — so the when-not side is left implicit.

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