Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds the key behavioral insight that 'balance' provides exact units while 'humanReadableBalance' is rounded for display, which is valuable guidance for interpreting tool output.
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 long, with the primary purpose front-loaded and the critical usage note provided immediately after. Every sentence adds value, with no redundant information.
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 simple balance-checking tool with no parameters, strong safety annotations, and no output schema, the description is complete. It includes the essential guidance about which balance field to use for trades, making it fully actionable.
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, so the schema coverage is effectively 100%. The description does not need to explain parameters; the baseline for zero-parameter tools is 4, and the description meets this by focusing on output guidance.
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 function: 'Get wallet balances on Base.' This specifies the verb (get), the resource (wallet balances), and the scope (Base chain), distinguishing it from sibling tools like bscGetBalances and ethGetBalances.
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 implies when to use the tool (for Base balances) and includes a critical note about using 'balance' for trades instead of 'humanReadableBalance'. It does not explicitly mention alternatives, but the chain-specific scope is clear from the description and sibling context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
With 113 tools spanning many chains and asset classes, there is substantial overlap. For example, listPositions and getAllPositions appear to serve the same function, and there are many balance, token discovery, and collection data tools that differ mostly by chain or protocol, making misselection likely.
Naming conventions are inconsistent: most tools use camelCase with a verb (baseGetBalances, ethSwapQuote), but some use underscores (nansen_defi_portfolio), others are just bare nouns (wallet, rugcheck), and there are irregularities like solanaBalances instead of solanaGetBalances, plus hederaTokensSwapQuote vs. baseSwapQuote.
The server exposes 113 tools, far beyond the typical well-scoped set. This is an extreme mismatch with the apparent purpose of a wallet/swap server, making discovery and selection difficult for agents.
While the server offers extensive read-only data (balances, market data, NFTs, positions), it lacks core write operations: there is no actual swap execution or token transfer tool, and the referenced emblemCreateVault tool is missing. These are significant gaps that will prevent agents from completing common wallet actions.
