Summarize vfat portfolio

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

Beyond the read-only and non-destructive annotations, the description adds useful behavioral context: it is cross-chain (implying multiple network queries) and relies on a provider for USD valuations. No contradictions with annotations are present.

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, front-loaded sentence without redundancy. Every word contributes to conveying the tool's purpose and output composition.

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, the description lists the returned components but does not detail the exact structure or format (e.g., how range status is represented). It is adequate for a compact summary tool but leaves some ambiguity about the response shape.

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 schema provides complete documentation for the single parameter (admin_address) with pattern and description. The tool description adds no additional parameter semantics, so a baseline score of 3 is appropriate given the high schema coverage.

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 with a specific verb ('Returns') and resource ('compact cross-chain position count, protocol breakdown, range status and provider-derived USD totals'). It distinguishes itself from sibling tools that focus on individual positions or actions by highlighting the cross-chain aggregate nature.

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?

Usage is implied through the word 'summary' and the compact nature of the output, suggesting use for a high-level overview. However, the description does not explicitly state when to use this tool over siblings like get_vfat_positions or get_vfat_position, nor does it mention any exclusions.

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