Behavior2/5

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

No annotations are present, so the description must disclose behavioral traits. It only includes pricing and a URL but omits whether the tool is read-only, rate limits (beyond free tier), authentication requirements, or any side effects. This is insufficient for safe invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short (two lines plus URL), which is concise but at the expense of necessary information. It front-loads the title and pricing, which is good, but the content is too minimal to be fully useful. It earns a 3 as it is not bloated but lacks structure and completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one param, no output schema), the description should at least hint at the type of data returned (e.g., balances, positions, totals). It does not, leaving the agent uncertain about the output format. For a DeFi tool with many siblings, this is insufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema covers the single parameter address with meaning 'wallet address'. The description adds no additional context beyond the schema. Baseline score is 3 due to 100% schema coverage; however, the description could have provided format or chain hints but did not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'DeFi position query' in Chinese and English, which directly explains the tool's purpose. It distinguishes from siblings like defi_insights or defi_lending_rates by focusing on positions. However, it lacks specificity about what constitutes a position (e.g., which protocols) and does not include example use cases.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. Given many sibling DeFi tools, such as defi_insights and defi_pool_stats, the description should clarify scenarios (e.g., querying a user's portfolio vs. protocol overview). The absence of such guidance makes it difficult for an agent to select correctly.

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