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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed world), and the description adds meaningful context on top: the scope is restricted to the key owner's own closed trades, amounts are denominated in USDT, and the output includes plain-language conclusions. It does not mention behavior when no trades match or any limits on the aggregation window.

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, front-loaded with what the tool returns, with the currency caveat appended where it belongs. No filler or repetition.

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 usefully enumerates the returned dimensions (net result, win rate, pair/side/month/weekday/hour breakdowns, leverage, streaks, conclusions) plus the USDT unit, so an agent knows what to expect. Minor gaps remain around empty-result behavior and defaults, though the schema covers defaults for the period.

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% and two parameters carry enums, so the schema already documents pair, side, time zone, period and connection filters. The description only restates that a period applies and that amounts are in USDT, adding little beyond the structured fields, which is the expected baseline.

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+resource: an aggregated summary of the owner's own closed trades, with an explicit enumeration of the metrics returned (net result, win rate, breakdowns, streaks, conclusions). It is clearly distinct from a raw trade list, though it never names tradeaudit_trades to make the contrast explicit.

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 only implied: 'Summary ... for a period' signals an analytics/overview use case, while the sibling tradeaudit_trades presumably returns individual trades. There is no explicit when-to-use, no exclusion, and no guidance on when to prefer one over the other.

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