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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds content scope about live economy and player wallet calls, but does not disclose return format, freshness, caching, or failure behavior beyond those 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 a single sentence followed by a short directive, front-loading the core purpose and then listing the relevant content areas. It is reasonably concise, though the embedded list makes it slightly dense.

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 no output schema and no parameters, the description should make clear what the tool actually returns. It lists information categories but does not specify whether the output is a prose guide, code snippets, structured data, or something else, leaving a gap for an agent trying to predict the result.

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?

The tool has zero parameters and an empty schema, so there is no parameter meaning to add. The baseline for a no-parameter tool is 4, and the description does not need to compensate for missing schema 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 clearly states the tool's content focus: client-side integration details for a Solana app, including program address and cluster, npm package and IDL, and wallet call patterns. It is not a precise verb+resource but is specific enough to distinguish the kind of information the tool provides.

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 directive 'Use this instead of writing chain code from memory' gives a clear when-to-use condition. It does not explicitly name sibling alternatives or state when not to use it, so it falls short of full alternative guidance.

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