OneQAZ Trading Intelligence

Group Context

get_group_context

Read-onlyIdempotent

Use when the question is about a sector, theme, ETF basket or index basket — its structure state and its members. Returns headline claims, the group's regime state per interval, its market, groups that co-move with it, member symbols with their latest signal bias, symbols the basket leads, and gaps. Not for a single stock (use get_symbol_context) or a whole market (use get_market_context). Provides regime, signal-score and linkage context with sample sizes and measured hit rates; every link carries its evidence and every empty section is listed in gaps. Not a real-time quote, fundamentals, or full-text news source. Output nature: Self-contained context for one entity: observed state, tracked links with their evidence and sample sizes, and explicit gaps. Not investment advice.

A4.6/5.0

Behavior5/5

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

Annotations already establish read-only and idempotent behavior, but the description adds substantial context beyond them: it lists returned sections, sample sizes, measured hit rates, evidence attached to every link, gaps for empty sections, and exclusions such as not a real-time quote, fundamentals, or full-text news source.

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 front-loaded with usage guidance and is generally efficient. It has some repetition between 'Returns...', 'Provides...', and 'Output nature...', but every sentence still contributes to scope or expectations.

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 the rich schema, annotations, and existing output schema, the description is complete enough for correct invocation: it covers purpose, scope, alternatives, exclusions, and the nature of the response without needing to explain return schema fields.

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 group, limit, question, and market_id. The description provides examples of acceptable group concepts but adds no syntax or constraints beyond what the schema provides, making the baseline 3 appropriate.

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 states a specific resource and scope: sector, theme, ETF basket, or index basket structure state and members. It explicitly distinguishes itself from get_symbol_context for a single stock and get_market_context for a whole market, so an agent can select it without opening sibling 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?

It gives explicit when-to-use guidance ('Use when the question is about a sector, theme, ETF basket or index basket') and clear when-not-to-use alternatives ('Not for a single stock (use get_symbol_context) or a whole market (use get_market_context)').

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