upgrade_transformation_package

Upgrades a Quickstart transformation package to the latest version. Provide a valid transformation identifier to initiate the update.

Instructions

⚠️ WRITE OPERATION - Confirm with user before calling. Upgrades the Quickstart transformation package to latest version 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/upgrade_transformation_package.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.
transformation_idYesThe unique identifier for the transformation
Behavior3/5

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

With no annotations provided, the description carries the full burden. It labels the tool as a 'WRITE OPERATION' and includes a warning emoji, indicating mutation. However, it does not disclose potential destructive consequences, required permissions, or whether the upgrade is reversible, which would be beneficial for a write operation.

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 extremely concise, consisting of a single sentence plus a warning. It is front-loaded with the critical warning and uses a clear emoji. There is no unnecessary information.

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?

The description lacks details about the tool's return value, error conditions, or what happens after a successful upgrade. Given that it is a write operation with no output schema, additional context would help the agent understand the outcome. However, the required schema file reading provides some completeness.

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 has 100% coverage with descriptions for each parameter. The tool description does not add extra meaning beyond the schema, so it meets the baseline of 3. The schema_file parameter description is detailed but is part of the schema, not the tool description.

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 verb 'upgrades' and the resource 'Quickstart transformation package', distinguishing it from related siblings like update_transformation or create_transformation. It specifies that it upgrades to the latest version given a valid identifier.

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?

The description includes a clear usage guideline: 'Confirm with user before calling.' It also notes that it works only if a valid identifier is provided. However, it does not explicitly state when not to use this tool or suggest alternatives among the many transformation-related siblings.

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