skavio_submit_job

DestructiveIdempotent

Enqueue a billable processing operation on company-owned uploads after obtaining a quote with skavio_estimate and authorization to spend. Set spec.operation, spec.upload_ids and spec.max_credits to an approved whole-credit ceiling; use one stable idempotency_key for this exact spec. Submission checks wallet, company/key budgets, adapter limits and current cost evidence before reserving credits. Returns a job object with id, status, estimated_credits and charged_credits; poll skavio_get_job until completed/failed, then skavio_download_result. Repeating identical arguments/key returns the same job; changed arguments conflict. After uncertainty never create a replacement key: retry identically or reconcile. Failures return isError with error_code/retryable.

Input Schema

Name	Required	Description	Default
`spec`	Yes	Processing workload over existing company-owned uploads. Obtain source IDs via an upload tool, select the permitted operation, then supply its options/fields. Estimate this spec first; submitting it additionally requires an explicit max_credits ceiling.
`idempotency_key`	Yes	Caller-selected stable identifier8-128 characters (letters, digits, underscore, dot, colon or hyphen) for exactly one upload or job intent. Reuse the same key with identical arguments after a retry; use a different key only for a genuinely new intent, never to bypass an uncertain outcome.

A4.7/5.0

Behavior5/5

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

Beyond annotations, it discloses that submission checks wallet, company/key budgets, adapter limits and current cost evidence before reserving credits, and that the operation is billable and destructive in the sense of spending credits. It also describes the returned job fields, polling flow, idempotent repeat behavior, conflict on changed arguments, and error shape with error_code/retryable.

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 dense but front-loaded, leading with the action and prerequisites before covering submission checks, return values, polling, idempotency, and failure behavior. Every sentence contributes operational guidance for a complex billable tool.

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

Completeness5/5

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

Given the rich input schema and annotations, the description fills the remaining gaps: billing prerequisites, credit reservation checks, return object fields, required polling, idempotency semantics, and error handling. No output schema is present, and the description still explains what a successful submission returns and how to continue.

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% and the nested spec fields are well documented, so the schema already carries most parameter meaning. The description reinforces the required spec.operation, spec.upload_ids and max_credits fields and ties idempotency_key to the exact spec, but it does not add substantially beyond the schema's own descriptions.

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 states a specific action, enqueueing a billable processing operation on company-owned uploads, and distinguishes it from the prerequisite estimate step. It names the exact sibling to use first (skavio_estimate) and the follow-up siblings (skavio_get_job, skavio_download_result), so the agent can place it in the workflow without opening another schema.

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

Usage Guidelines5/5

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

It explicitly says to obtain a quote with skavio_estimate and authorization to spend before submitting, which is a clear when-to-use rule. It also gives post-submission guidance: poll skavio_get_job until completed/failed, then call skavio_download_result, and defines idempotency behavior for retries versus genuinely new intents.

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