get-table-by-name

Retrieve detailed information about a specific table by providing its fully qualified name (e.g., 'service.db.schema.table'). Customize response with optional fields and includes.

Instructions

Get table details by fully qualified name

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fqnYesFQN (e.g. 'service.db.schema.table')
fieldsNoOpenMetadata fields to include
includeNo
extractFieldsNoComma-separated dotted paths to project from response (e.g. 'id,name,owner.name,columns.*.name'). Use `*` as wildcard for arrays/objects. Wrap field names with dots in backticks. Reduces response tokens dramatically on large entities.
Behavior1/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It fails to mention permissions, response format, pagination, or any side effects. The description is too sparse to inform agent decisions.

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 single-sentence description is concise and front-loaded, but its brevity sacrifices completeness. Every word earns its place, but more detail is needed to be genuinely helpful.

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

Completeness2/5

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

Given no output schema, no annotations, and a complex set of sibling tools, the description should at least hint at the returned fields or include a reference to the OpenMetadata API. It falls short of providing a complete picture.

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 coverage is 75%, and the description adds no extra meaning beyond the schema. The 'fields' parameter description is present in schema but not elaborated in the tool description. Baseline 3 is appropriate as the schema does the heavy lifting.

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 action ('Get'), resource ('table details'), and method ('by fully qualified name'). It distinguishes itself from other 'get-*' tools by specifying the resource type and the exact identifier format.

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

Usage Guidelines2/5

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

No guidance on when to use this tool versus alternatives like 'get-table' (presumably by ID) or 'get-table-summary'. The description does not mention any prerequisites, fallbacks, or preferred scenarios.

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