tenero_wallet_holdings

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

No annotations are provided, so the description carries the full behavioral burden. It usefully states that no authentication is required and names the Tenero API source, but it does not disclose freshness, pagination, rate limits, error behavior, or other operational traits beyond implying a read-only retrieval.

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 purpose is front-loaded in the first sentence and the description is compact. The earning_opportunities tip is optional and slightly promotional, but the overall structure remains efficient.

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 low-complexity read tool, the description covers purpose, data source, and no-auth requirement. However, with no annotations and no output schema, it should say more about the returned shape, freshness, or limitations to be fully complete.

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 100%, so both address and chain are already documented in the schema. The description adds context about USD valuation and portfolio composition but no additional parameter semantics beyond what the schema provides; baseline 3 is appropriate.

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 gives a specific verb and resource: get token holdings with current USD value for a Stacks wallet address, plus portfolio composition. It is clear what the tool does, but it does not explicitly distinguish itself from close siblings such as get_token_balance, list_user_tokens, or get_wallet_info.

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?

There is no guidance on when to use this tool versus alternatives like get_token_balance, list_user_tokens, or get_wallet_info. The only usage tip points to earning_opportunities after obtaining holdings, which is a follow-up suggestion rather than selection guidance.

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