OneQAZ Trading Intelligence

Trading Signals

get_signals
Read-onlyIdempotent

Purpose: Query signals with dynamic filters (symbol / interval / action / score / confidence). Triggers (casual questions too): "what's the signal for BTC / AAPL / 삼성전자?", "is X bullish or bearish?", "how does X look right now?". When the user asks whether to trade X, OneQAZ gives context (regime, score, measured past hit rate of similar scores), not a conclusion: pass it on as context and do not turn it into a trade call. Always surface the disclaimer. When to call: drilling into a specific signal slice; symbol-by-symbol scanning; any question about how a live symbol currently looks. Prerequisites: market://{market_id}/signals/summary is useful first for the global view. Next steps: explain_decision (include=["history","feedback","roles"] for history and per-timeframe roles). Caveats: When symbol/coin is omitted, the whole market is scanned in one consolidated query (2 newest rows per symbol, newest-first scan cap per interval). Results are capped: check truncated / truncated_note before reading the set as "the whole market". Fields that are identical across every returned row are hoisted into common and omitted from the rows (see common_note); a row-level key, when present, wins over common. warnings carries only the flags that are true and is omitted entirely when none are. reason_uncalibrated: true on a row points at the response-level reason_uncalibrated_note. Output nature: Observed signal state computed from live market prices each cycle. signal_score is an internal ranking score, not a probability; bias is its sign. Context for the user's question, not investment advice.

A4.8/5.0
Behavior5/5

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

Annotations already declare readOnly/idempotent/closed-world, and the description goes well beyond them: consolidated whole-market scan when symbol is omitted, cap behavior with truncated/truncated_note, hoisting of identical fields into `common` with row-level precedence, warnings omission, and reason_uncalibrated noting. It also states the framing obligation (pass results as context, never a trade call, always surface disclaimer), which is behavior no annotation conveys.

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

Conciseness4/5

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

Front-loaded with labeled sections (Purpose / Triggers / When to call / Prerequisites / Next steps / Caveats / Output nature), so an agent can scan quickly. It is dense and somewhat long, with quoted example questions and some restatement of schema details (coin as legacy alias), but almost every sentence carries operational value.

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?

Output schema exists so return structure need not be described, yet the description still covers the response-level quirks (common hoisting, truncated flags, warnings, reason_uncalibrated), required parameter semantics, prerequisites, and follow-up tools. Nothing an agent needs to interpret or correctly call this 9-parameter tool is missing.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3; the description still adds meaning by explaining that omitting symbol/coin triggers a whole-market consolidated scan and that signal_score is an internal ranking score (bias is its sign), not a probability. Remaining parameters (min_score, min_confidence, limit) are left to the schema, so it is not fully additive.

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

Purpose5/5

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

Opens with an explicit verb+resource plus the exact filter dimensions ('Query signals with dynamic filters (symbol / interval / action / score / confidence)'), and distinguishes itself from the summary resource, explain_decision, and get_symbol_context. An agent can tell this apart from sibling calibration/context tools without opening any schema.

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

Usage Guidelines5/5

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

Provides explicit triggers including casual phrasings, a 'When to call' section, a prerequisite (market://{market_id}/signals/summary for the global view), and named next steps (explain_decision with specific include values). This is the when/when-not/alternatives pattern done fully.

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