get_signals

Read-onlyIdempotent

Purpose: Query research signals with dynamic filters (symbol / interval / action / score / confidence). Triggers (casual questions too): "should I buy / sell X?", "살까 말까?", "good entry?", "what's the signal for BTC / AAPL / 삼성전자?", "is X bullish or bearish?", "any buy signals right now?". Returns a research signal + score (NOT an order or advice — always surface the disclaimer). Pair with get_latest_decisions to show what the system did. When to call: drilling into a specific signal slice; symbol-by-symbol scanning; any "should I trade X?" question about a live symbol. Prerequisites: market://{market_id}/signals/summary recommended for global view. Next steps: get_signal_detail, get_role_analysis. 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.

A4.8/5.0

Behavior5/5

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

Annotations already declare readOnlyHint and idempotentHint, and the description goes well beyond them by disclosing behavior: whole-market scan when symbol/coin is omitted, row caps per symbol and interval, truncated/truncated_note fields, common-field hoisting with row-level precedence, warnings omission behavior, and reason_uncalibrated semantics. This richly informs the agent about what the tool actually does.

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?

The description is longer than average but well-organized into Purpose, Triggers, When to call, Prerequisites, Next steps, and Caveats. It front-loads the core purpose and includes only behaviorally important caveats. The trigger list and 'When to call' section overlap somewhat, preventing a 5, but no sentence is wasted.

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?

Given 9 parameters, an output schema, and a complex return shape, the description covers all essential behavioral context: filtering, output caps, field hoisting, warnings, uncalibration notes, disclaimer handling, and relationships to sibling tools. Nothing needed for correct invocation 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 the schema already documents all parameters; baseline is 3. The description adds meaning beyond the schema by explaining omission behavior for symbol/coin (whole-market scan, 2 newest rows per symbol, per-interval cap) and how truncation flags should be read, which directly affects parameter interpretation.

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?

Description states a specific action ('Query research signals') with concrete filter dimensions (symbol/interval/action/score/confidence) and clearly distinguishes it from order execution by noting it returns a signal, not an order or advice. It also names related siblings (get_latest_decisions, get_signal_detail, get_role_analysis), so an agent can place this tool in context.

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 when-to-call guidance, full natural-language trigger examples, a pairing suggestion with get_latest_decisions, a prerequisite recommendation, and next-step tools. This is unusually complete usage guidance that tells the agent both when the tool is appropriate and what else to consider.

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