generate_test_data

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

No annotations provided, so description carries full burden. It discloses key behaviors: supports foreign key relationships across tables, auto-locale via country field, multiple output formats, and reproducibility via seed. These are beyond the input schema.

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

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

Description is concise and front-loaded: first sentence states purpose, then bullet-like details on features. No wasted words; every sentence adds value. Well-structured for an AI agent.

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

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

Covers input modes, relational data, locales, formats, and reproducibility. Missing explicit description of output structure (since no output schema), but mentions formats (JSON, CSV, SQL) which implies the output content. Slightly incomplete, but overall sufficient for a generation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so description adds limited new meaning per parameter. It reiterates the two modes and adds context on auto-locale and seeding, but most parameter semantics are already in the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it generates realistic test data for database tables, and highlights two input modes (structured schema or plain English). It distinguishes from siblings like detect_schema (schema detection) and list_field_types (type listing) by focusing on generation with relational integrity and locales.

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

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

The description explains when to use this tool: to generate test data from a schema or plain description. It implies generating from scratch vs. using templates (generate_from_template), but doesn't explicitly contrast with siblings. Clear guidance on input modes is provided.

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