Crypto spot quote

hubvibe_market_quote

Read-onlyIdempotent

Crypto price / live coin quote: spot price, 24-hour change and 24-hour volume for Bitcoin, Ethereum, Solana or any Coinbase product (BTC-USD, ETH-USD, SOL-USD...), read at call time from Coinbase's public market data. Use it when an agent needs a current cryptocurrency price. Input: product_id such as BTC-USD. Bid/ask: market.ticker. Whole rate table: market.rates. $0.10 per call. Returns: price, price_change_24h_pct, volume_24h, base/quote currency.

TDQS

A4.6/5.0

Behavior5/5

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

Annotations already cover read-only/idempotent/non-destructive/open-world, but the description adds non-annotation facts that matter for agent decisions: the quote is 'read at call time' (freshness, no caching), sourced from 'Coinbase's public market data', and costs '$0.10 per call'. Cost and data provenance are exactly the context structured fields don't carry.

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 core capability is front-loaded in the first clause and the whole entry fits one tight paragraph. Some content is redundant with structured fields (the field-by-field 'Returns:' list duplicates the output schema), which keeps it from a 5.

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?

With an output schema present, the description needn't explain return values, yet it still summarizes them; annotations carry the safety profile and the schema carries parameter docs. Combined with source, freshness, cost and sibling routing, an agent has everything needed to call this correctly.

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%, so the baseline is 3. The description repeats the product_id example format ('BTC-USD') already present in the schema and adds the useful hint that any Coinbase product works, but it says nothing about the optional `language` parameter, so it does not meaningfully exceed the schema.

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?

The description names a concrete resource and verb ('Crypto price / live coin quote: spot price, 24-hour change and 24-hour volume') and enumerates the exact products covered (BTC-USD, ETH-USD, SOL-USD, any Coinbase product). It also distinguishes itself from the nearest siblings by assigning bid/ask to market.ticker and the full rate table to market.rates, so the agent can route without opening other schemas.

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?

'Use it when an agent needs a current cryptocurrency price' states the triggering condition explicitly. The sibling routing notes ('Bid/ask: market.ticker. Whole rate table: market.rates.') give concrete alternatives with the condition that selects each, leaving little to inference.

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