get_market_sell_value

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

With no annotations provided, the description fully carries the behavioral transparency burden. It discloses that the tool matches against current buylist offers, caps by buy quantity, groups by vendor, and returns per-item payouts and totals. This gives reasonable insight into its behavior.

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 concise, packing several important details into two sentences. It is efficient, though a slight structuring with bullet points could improve readability.

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?

The description explains the logic and output conceptually, but without an output schema, it would benefit from more detail on the response structure, such as example fields or nesting. The coverage is adequate but not 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?

There are no parameters, so the baseline is 4. The description appropriately adds no parameter information, as there is nothing to clarify beyond the schema.

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 purpose: computing market sell value of the user's inventory by matching against buylist offers. It details the process and distinguishes from sibling tools like get_portfolio_summary by focusing on buylist-based valuation.

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 explains what the tool does and notes the requirement for an API key, but does not explicitly state when to use this tool versus alternatives or when not to use it. No guidance on context like frequent use or refresh needs.

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