Live stock quote and daily history

hubvibe_market_stock

Read-onlyIdempotent

Stock price / live stock quote for any US ticker: last price, change, day range, volume and market state, plus daily OHLCV history (1d to 5y), read at call time from Nasdaq's public data with Yahoo Finance as fallback. Every answer names its source, the source's timestamp, its delay in minutes and when it was read. Input: symbol (AAPL, NVDA...); optional range, include_history. $0.05 per call. Returns: symbol, name, exchange, currency, price, change, change_pct, previous_close, day_high, day_low, volume, market_state, as_of, delayed_minutes, history[], history_rows, source, checked_at.

A3.8/5.0

Behavior5/5

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

Annotations already cover the read-only/idempotent/open-world safety profile, but the description adds material behavioral context on top: the upstream sources (Nasdaq public data, Yahoo fallback), that data is read at call time, that every response names its source, source timestamp, delay in minutes, and read time, and the $0.05 per-call cost. Cost and staleness disclosure are exactly the kind of information annotations cannot express and an agent must know before invoking.

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

Conciseness3/5

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

The lead sentence front-loads the purpose and sources well, but the trailing 'Returns: symbol, name, exchange, ...' enumeration of ~18 fields is redundant given an output schema exists, and the whole thing is a single dense run-on paragraph. Recoverable, but not every sentence earns its place.

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

Completeness4/5

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

For a read-only, single-symbol market lookup with a full output schema, the description covers sources, freshness, delay, cost and inputs, so an agent has enough to call it correctly. The one meaningful gap is the absence of sibling disambiguation within the large market_* tool family.

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 schema already documents symbol, range, include_history and language with patterns, enums and defaults. The description restates symbol/range/include_history but adds no format or behavioral nuance, and omits language entirely. Baseline 3 is correct when the schema carries the parameter burden.

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 names a specific verb+resource: live stock quote (last price, change, day range, volume, market state) plus daily OHLCV history, scoped to US tickers. That is far more than a restatement of the name. However, it never differentiates itself from the very close siblings hubvibe_market_quote, hubvibe_market_ticker and hubvibe_market_intel, so an agent comparing candidates gets no routing signal.

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

Usage Guidelines3/5

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

Usage is only implied: 'for any US ticker' and '1d to 5y' bound the scope, and call-time reading from Nasdaq/Yahoo tells the agent it is a live pull. There is no explicit when-to-use statement and no mention of when a sibling (e.g. market_quote for a bare quote, or market_fundamentals) would be the better pick despite the crowded market_* family.

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