delete_transformation

Deletes a transformation permanently using its unique identifier. Requires user confirmation to proceed.

Instructions

⚠️ DESTRUCTIVE - Confirm with user before calling. Deletes a transformation if a valid identifier is provided.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
schema_fileYesREQUIRED: You must first read the schema file at 'open-api-definitions/transformations/delete_transformation.json', then provide this exact path here to confirm.
transformation_idYesThe unique identifier for the transformation
Behavior4/5

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

No annotations provided, so description carries full burden. Includes strong destructive warning and confirmation requirement. Does not detail other behavioral aspects like side effects or error states, but sufficient for a deletion tool.

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?

Extremely concise: two-part structure (warning then action). Every sentence adds value. No redundancy.

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?

Covers purpose, guidelines, and parameter semantics. However, lacks information on return value or success/failure indicators, especially given no output schema. Could be slightly more complete.

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

Parameters4/5

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

Schema coverage is 100%, but description adds crucial context for schema_file parameter: it serves as a confirmation step requiring prior file read. transformation_id description matches schema. Adds value beyond schema.

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?

Clearly states action ('Deletes a transformation') and condition ('if a valid identifier is provided'). Distinguishes from sibling tools like create_transformation, update_transformation.

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

Usage Guidelines4/5

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

Explicitly warns about destructiveness and requires user confirmation. Does not directly compare to alternatives like cancel_transformation, but gives clear context for when to call.

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