Get market trades

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile needs no restating. The description adds one real behavioral trait the annotations do not cover — 'Weight: 1' (rate-limit cost) — but says nothing about ordering, recency window, or how far back 'recent' extends.

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 very short lines, front-loaded with the core action before the weight note. Minimal waste, though 'Get market trades' restates the title and could be folded into the body.

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?

For a simple read-only market-data tool with full schema coverage and annotations covering the safety profile, the description is nearly sufficient. The only meaningful gaps are the recency window and ordering, which are minor for this tool class.

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 100%, so symbol and limit (with default 100 and range 10-500) are already documented in the schema. The description adds no extra meaning such as sort order, what limit actually caps, or time semantics of the returned trades.

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?

States a specific verb and resource ('Get recent trades'), so the agent knows this returns recent executed trades for a symbol. However, it does not differentiate from closely related siblings such as pionex_market_get_klines or pionex_orders_get_fills, so the boundary is left to inference.

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 when-to-use guidance, no alternatives, and no exclusions are given. 'Get recent trades' implies a market-data read, but there is nothing telling the agent when to prefer this over get_klines or get_depth.

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