get_nodes_info

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

No annotations are provided, so the description carries the full disclosure burden. It implies a harmless read of type metadata and adds useful workflow context, but says nothing about whether the returned types are global or scoped to a project/scheme, how large the payload is, or whether the result is static and safe to cache.

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?

Two short sentences with zero filler: the first defines what is returned, the second the sequencing rule, and the precondition is front-loaded where the agent will act on it.

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 zero-parameter, no-output-schema introspection tool this is nearly complete: what it returns (node/trigger/action types and their config options) and when to call it are both stated. Only the scoping of results and the general shape of the returned config options are left implicit.

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?

Zero parameters, so the schema baseline is 4. The description correctly implies no input is needed to retrieve type information, and there is nothing for it to compensate for.

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?

States a specific verb and resource ("Get information about available node types") and enumerates the subtypes it covers (trigger_types, action_types) plus their configuration options. An agent can distinguish this discovery tool from the node_create_trigger / node_create_action siblings, though it never names those siblings directly.

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?

"Call this first to see available types before creating nodes" gives an explicit ordering precondition and ties it to the node-creation workflow. It stops short of stating exclusions (e.g., when to skip it because types are already known) or naming alternatives, so it lands at 4 rather than 5.

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