test_transformation_project

Triggers tests for an existing transformation project to validate its functionality.

Instructions

⚠️ WRITE OPERATION - Confirm with user before calling. Triggers tests for an existing transformation project.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
project_idYesThe unique identifier for the transformation project
schema_fileYesREQUIRED: You must first read the schema file at 'open-api-definitions/transformation-projects/test_transformation_project.json', then provide this exact path here to confirm.
request_bodyYesJSON string containing the request body. Refer to the schema file for the expected structure.
Behavior2/5

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

No annotations are provided, so the description must fully disclose behavior. It only labels it as a 'WRITE OPERATION' and says it triggers tests, but does not explain what the tests involve, potential side effects, or what happens to the project. This is insufficient for an agent to anticipate consequences.

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?

The description is a single sentence that front-loads the critical warning ('WRITE OPERATION - Confirm with user'). It is concise and avoids redundancy, though it could benefit from slightly more structure (e.g., breaking into purpose and usage).

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 the absence of annotations and output schema, the description should provide richer context about return values, test outcomes, and behavioral implications. It only covers basic purpose and a warning, leaving significant gaps for safe invocation.

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 100%, so the baseline is 3. The description adds no additional meaning beyond the schema's parameter descriptions. The warning is not parameter-specific, so no extra value for parameter understanding.

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?

The description clearly states that the tool triggers tests for an existing transformation project, which is a specific verb-resource combination. However, it does not differentiate from sibling tools like 'run_transformation' or other test-related tools, so it misses full uniqueness.

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?

The only usage guidance is a warning to confirm with the user before calling. It does not specify when to use this tool vs. alternatives (e.g., 'run_transformation'), nor does it mention prerequisites or conditions.

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