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

With no annotations, the description must carry the behavioral burden, and it does: it states the action is authorized-only and explicitly explains that a pending_approval result means nothing ran, that the user needs the review link, and that the identical call should be retried after approval. It does not disclose all side-effect or failure possibilities, but the key approval-gating behavior is well covered.

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 compact and front-loaded with the action, followed by two high-value sentences about authorization and pending-approval handling. Every sentence earns its place and there is no filler.

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?

The essential approval-retry flow is covered, and an output schema exists, so return values need not be described. However, with no annotations and no parameter-level descriptions, the tool is not fully complete for an agent that must correctly populate node_type and arguments.

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 0%, so the description needed to explain the four required parameters. It gives only indirect hints: 'connection' maps to credential_id and 'discovered operation' maps to operation. It does not help the agent construct arguments or understand node_type, and the schema itself offers no descriptions.

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 opens with a specific verb-resource pair: 'Execute one discovered operation directly using a connection.' The word 'discovered' signals that this tool is for running an already-found operation rather than for listing or searching operations, which distinguishes it from siblings like get_node_operations and search_operations.

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 clear invocation context: use after discovery and after user authorization, and retry only after approval when a pending_approval result is returned. It does not explicitly name sibling tools as alternatives or list when-not-to-use conditions, but the authorization and approval workflow provides useful usage guidance.

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