get_examples

Filter SQL query examples to only those matching object classes present in your database. Provide object class IDs to get relevant examples.

Instructions

Returns SQL query examples filtered to only include examples for object classes that exist in the database.

Behavior2/5

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

No annotations are provided, so the description must fully convey behavior. It only mentions filtering, but fails to disclose whether the operation is read-only, what happens with invalid IDs, the output format, or any side effects.

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

Conciseness5/5

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

The description is a single sentence, front-loaded with the action, and contains no unnecessary words. Every word contributes to understanding the tool's purpose.

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

Completeness3/5

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

For a simple one-parameter tool, the description is minimally complete. However, it lacks details about the return format, error handling, and any constraints on the objectclass_ids, which would be necessary for an agent to invoke it confidently without relying on prior knowledge.

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?

The input schema fully documents the only parameter (objectclass_ids) with a description similar to the tool's description. The tool description adds no additional meaning beyond what the schema already provides, matching the baseline for high schema coverage.

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 clearly states the tool returns SQL query examples, and specifies a filtering condition to only include examples for existing object classes. This distinguishes it from sibling tools like get_database_schema or run_query.

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?

The description implies when to use: when you need filtered SQL examples. However, it does not provide explicit guidance on when not to use this tool or mention alternatives among the siblings, leaving it to the agent to infer.

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