get-chart

Fetch chart metadata by UUID. Select specific fields, include deleted or all charts, and extract nested properties using dot notation.

Instructions

Get chart details by UUID

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesChart UUID
fieldsNoComma-separated 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.
Behavior2/5

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

No annotations provided; description fails to disclose behavioral aspects such as ability to retrieve deleted charts (implied by include parameter) or any side effects. The description is too brief.

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?

Description is a single concise sentence, no wasted words. However, it could be expanded to include key behavioral details without losing conciseness.

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?

With 4 parameters, no output schema, and no annotations, the description is insufficient. It does not explain return values, effect of optional parameters, or how it differs from similar tools like get-chart-by-name. The include parameter's enum options are relevant but not described.

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 high (75%), so baseline is 3. The description does not add any additional meaning beyond the schema for parameters like fields, include, or extractFields. It does not compensate for the undocumented include parameter.

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?

Description clearly states verb 'Get' and resource 'chart details' with identifier 'UUID'. However, it does not distinguish from sibling tool 'get-chart-by-name' which retrieves chart by name instead.

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-chart-by-name. It does not specify prerequisites or context for using the include parameter.

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