dataset_ingest

Starts a remote URL ingest job for a dataset by slug or URI, reporting the queued job ID and current ingest status. Use datasets_get to follow up.

Instructions

Start a remote URL ingest job for a dataset by slug, owner/slug, or a ul://owner/datasets/slug URI. Defaults conflictPolicy to skip (the platform default is undocumented). Reports the queued job id with the dataset's current ingest status; use datasets_get to follow up.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare the mutation and open-world profile, so the bar is lower, and the description adds real context: the job is asynchronous (queued job id), conflictPolicy defaults to skip while the platform default is undocumented, and it returns the dataset's current ingest status. It stops short of describing auth requirements or failure modes.

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?

Two tight sentences, front-loaded with the action and reference formats, then the default and the follow-up hint. No wasted text, though the parenthetical about the undocumented default is slightly verbose.

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

Completeness4/5

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

For a mutation tool with no output schema, the description usefully explains what comes back (queued job id plus current ingest status) and points to the follow-up tool, covering the async lifecycle. It does not address permissions or what happens on ingest failure, so it is not fully complete.

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 100%, so the baseline is 3. The description mostly restates what the schema already documents (dataset ref formats, conflictPolicy default of skip); the only added nuance is that the platform default is undocumented, which is marginal.

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?

States a specific verb (start ingest job), the resource (remote URL ingest for a dataset), and the accepted dataset reference formats. This clearly distinguishes it from the local-upload siblings (dataset_upload_file/folder/video) and from datasets_get.

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?

Names the follow-up tool explicitly ('use datasets_get to follow up'), which gives the agent a clear next step. It does not, however, state when to prefer this over the local-upload siblings, leaving that distinction to inference from the 'remote URL' wording.

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