get_set_price_history

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

No annotations provided, but description explains that the tool returns aggregate value over time. Does not mention rate limits, authentication, or error cases, but is sufficient for a simple read-only query tool.

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?

Two sentences, zero fluff. First sentence defines purpose, second sentence adds optional parameter and sibling guidance. Front-loaded and 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?

No output schema; description gives high-level result concept ('aggregate value over time') but does not specify return format (array, timestamps, etc.). Lacks full completion for agent to understand output.

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 coverage is 100%, so baseline is 3. Description restates parameter purposes ('limit the window with days') but adds no new semantic detail 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?

Clearly states verb 'Get', resource 'price history for a whole set', and method 'by set code'. Explicitly distinguishes from sibling 'get_card_price_history'.

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?

Provides explicit conditions: optional 'days' parameter limits the window, and directs to 'get_card_price_history' for single card history. Clear when-to-use and when-not-to-use.

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