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

No annotations provided, so description carries full burden. Only mentions 'risk watch' and cost, omitting whether it is read-only, requires specific permissions, or any side effects. No explanation of returned data structure.

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?

Extremely short but under-specified; wastes space on cost note without adding useful context. Lacks structure such as input/output hints or usage examples.

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 2 parameters, no output schema, and no annotations, description provides almost no actionable information. Agent cannot determine what data is returned or how to interpret results.

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 0% and description does not explain any parameter. 'chain' with default 'all' and required 'api_key' are left completely undefined, forcing the agent to guess their meaning.

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?

Description uses vague verb 'watch' and ambiguous resource 'DeFi positions', fails to specify output type (list, status, etc.). $0.02 indicates cost but does not clarify purpose. No differentiation from sibling tools like get_portfolio_health or get_defi_pools.

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?

No guidance on when to use this tool versus alternatives like get_portfolio_health or get_whale_moves. Context of liquidation monitoring is implied only from name, not described.

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