Spot quote

spot_quote

Read-only

Fetch a read-only spot market quote to see live execution price, estimated cost, available balance, and fill eligibility before placing an order. Use it to avoid blind trades in paper trading.

Instructions

Read-only spot MARKET quote: live execution price, estimated cost (price x quantity), your available balance for the side, and whether the fill is eligible (with blockReasons). Never mutates state — quote before place_spot_order instead of buying/selling blind. Price age is informational only (a market order fills regardless). coinId is a UCID, NOT a ticker — use resolve_symbol first. Paper trading only (virtual mUSD). Fills follow paper_execution_v1 with a disclosed execution cost; see executionModel in quote/trade results.

TDQS

A4.8/5.0

Behavior5/5

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

Annotations only declare readOnly/destructive/openWorld, but the description adds substantial context: it never mutates state, price age is informational because market orders fill regardless, it is paper trading only (virtual mUSD), fills follow paper_execution_v1 with a disclosed execution cost visible via executionModel. This is meaningfully more than the safety hints alone.

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?

Dense but front-loaded: the read-only quote nature and its outputs come first, then the guidance, then the caveats (price age, UCID, paper trading, execution model). Slightly overloaded with distinct caveats in a single block, but every sentence carries information an agent needs.

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?

An output schema exists, so return-field documentation is not required, yet the description still flags blockReasons and executionModel. Combined with the paper-trading and execution-model notes, an agent has everything needed to call this correctly and interpret the result.

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 baseline is 3, but the description adds value by reinforcing that coinId is a UCID (not a ticker) and must be produced by resolve_symbol, which changes how the caller prepares the argument. It does not, however, clarify the semantics of agentTrace beyond what the schema already documents.

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?

States a precise verb and resource ('Read-only spot MARKET quote') and enumerates exactly what it returns: live execution price, estimated cost, available balance, and fill eligibility with blockReasons. This makes it immediately distinguishable from sibling tools like futures_quote, pm_quote, and place_spot_order.

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?

Explicitly routes the agent: 'quote before place_spot_order instead of buying/selling blind' and 'use resolve_symbol first' to convert a ticker to a coinId. It names both the downstream alternative and the prerequisite tool, leaving nothing to inference.

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