Get SAP Network Overview

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds value by specifying that this is a read-only wrapper against a configured Solana RPC and SAP program, and explains the source of the data (SDK DiscoveryRegistry.getNetworkOverview).

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: the first specifies the action and source, the second gives usage context. No unnecessary information, and it is front-loaded with the core purpose.

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 tool has no parameters, rich annotations, and an output schema (not shown but present), the description provides sufficient context for an agent to understand when and why to use it. It mentions the underlying SDK method and the pre-mutation use case.

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?

There are no parameters, so the description does not need to add meaning. The schema coverage is 100%, and the description appropriately does not clutter with parameter details.

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 it fetches real network counters from SDK DiscoveryRegistry.getNetworkOverview, using a specific verb and resource. It situates the tool within the SAP MCP context and distinguishes it from sibling tools that fetch specific accounts or perform mutations.

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 advises using this read to inspect current chain state before mutating accounts, providing a clear context. It does not explicitly list when not to use, but the guidance is sufficient given the sibling tools for more specific reads.

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