get_trade_history

Read-onlyIdempotent

Purpose: Query paper-trading history with dynamic filters (action / P&L / time / symbol). Triggers (casual questions too): "what trades happened lately?", "최근 거래 내역 보여줘", "how did the BTC trades go?", "승률 어때?", "show me the trade log", "how many trades won this week?". When to call: past trade review, single-symbol post-mortem, win-rate audits. Prerequisites: none. Next steps: analyze_trades, market://{market_id}/signals/feedback. Caveats: paper-trading data only (not real money). limit capped at 1000.

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, so the safety profile is known. The description adds the critical caveat that data is paper-trading only (not real money) and notes the limit cap of 1000, which is useful behavioral context beyond the annotations. It doesn't repeat what annotations cover, and it doesn't contradict them. The extra disclosure about paper-trading justifies a 4.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear headings: Purpose, Triggers, When to call, Prerequisites, Next steps, Caveats. The purpose is front-loaded, and every section earns its place — even the trigger examples and next-step tools are useful for an agent deciding when to call and what to do after. There is no fluff, and the formatting aids scannability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters, an output schema, and rich annotations, the description is complete: it covers the operation's purpose, usage contexts, prerequisites (none), follow-up tools, and caveats (paper-trading scope, limit cap). It doesn't need to explain return values because an output schema exists. The only minor gap is explicit differentiation from siblings, but that is not required for completeness given the clear purpose.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% — every parameter (limit, symbol, max_pnl, min_pnl, market_id, hours_back, action_filter) has a detailed description, including defaults, aliases, and the stats_scope nuance. The tool description only summarizes filters ('action / P&L / time / symbol') and does not add meaning beyond the schema. Per the rubric, with high schema coverage the baseline is 3, and the description adds no extra parameter insight.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with 'Query paper-trading history with dynamic filters (action / P&L / time / symbol)', which clearly identifies the verb (query), resource (paper-trading history), and scope (filters). It does not explicitly differentiate from siblings like get_winning_trades or get_trade_outcomes_bulk, but the name and the filter list make its general-purpose nature evident. It could be a 5 with an explicit 'for specialized trade subsets, use X' note, so 4 is appropriate.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'When to call' section lists concrete scenarios (past trade review, single-symbol post-mortem, win-rate audits) and the 'Triggers' section provides natural-language examples that help an agent recognize user intents. It does not explicitly state when NOT to use this tool or point to alternatives like get_winning_trades, but the listed contexts are clear enough to guide selection. A 4 reflects strong guidance that stops short of explicit exclusions.

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