Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Doubleword Batch Inference

Process multiple AI inference requests asynchronously using the Doubleword batch API.

When to Use Batches

Batches are ideal for: Multiple independent requests that can run simultaneously Workloads that don't require immediate responses Large volumes that would exceed rate limits if sent individually Cost-sensitive workloads (24h window offers better pricing)

Quick Start

Basic workflow for any batch job: Create JSONL file with requests (one JSON object per line) Upload file to get file ID Create batch using file ID Poll status until complete Download results from output_file_id

Step 1: Create Batch Request File

Create a .jsonl file where each line contains a single request: {"custom_id": "req-1", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "anthropic/claude-3-5-sonnet", "messages": [{"role": "user", "content": "What is 2+2?"}]}} {"custom_id": "req-2", "method": "POST", "url": "/v1/chat/completions", "body": {"model": "anthropic/claude-3-5-sonnet", "messages": [{"role": "user", "content": "What is the capital of France?"}]}} Required fields per line: custom_id: Unique identifier (max 64 chars) - use descriptive IDs like "user-123-question-5" for easier result mapping method: Always "POST" url: Always "/v1/chat/completions" body: Standard API request with model and messages Optional body parameters: temperature: 0-2 (default: 1.0) max_tokens: Maximum response tokens top_p: Nucleus sampling parameter stop: Stop sequences File limits: Max size: 200MB Format: JSONL only (JSON Lines - newline-delimited JSON) Split large batches into multiple files if needed Helper script: Use scripts/create_batch_file.py to generate JSONL files programmatically: python scripts/create_batch_file.py output.jsonl Modify the script's requests list to generate your specific batch requests.

Step 2: Upload File

Upload the JSONL file: curl https://api.doubleword.ai/v1/files \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" \ -F purpose="batch" \ -F file="@batch_requests.jsonl" Response contains id field - save this file ID for next step.

Step 3: Create Batch

Create the batch job using the file ID: curl https://api.doubleword.ai/v1/batches \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "input_file_id": "file-abc123", "endpoint": "/v1/chat/completions", "completion_window": "24h" }' Parameters: input_file_id: File ID from upload step endpoint: Always "/v1/chat/completions" completion_window: Choose "24h" (better pricing) or "1h" (50% premium, faster results) Response contains batch id - save this for status polling.

Step 4: Poll Status

Check batch progress: curl https://api.doubleword.ai/v1/batches/batch-xyz789 \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" Status progression: validating - Checking input file format in_progress - Processing requests completed - All requests finished Other statuses: failed - Batch failed (check error_file_id) expired - Batch timed out cancelling/cancelled - Batch cancelled Response includes: output_file_id - Download results here error_file_id - Failed requests (if any) request_counts - Total/completed/failed counts Polling frequency: Check every 30-60 seconds during processing. Early access: Results available via output_file_id before batch fully completes - check X-Incomplete header.

Step 5: Download Results

Download completed results: curl https://api.doubleword.ai/v1/files/file-output123/content \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" \ > results.jsonl Response headers: X-Incomplete: true - Batch still processing, more results coming X-Last-Line: 45 - Resume point for partial downloads Output format (each line): { "id": "batch-req-abc", "custom_id": "request-1", "response": { "status_code": 200, "body": { "id": "chatcmpl-xyz", "choices": [{ "message": { "role": "assistant", "content": "The answer is 4." } }] } } } Download errors (if any): curl https://api.doubleword.ai/v1/files/file-error123/content \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" \ > errors.jsonl Error format (each line): { "id": "batch-req-def", "custom_id": "request-2", "error": { "code": "invalid_request", "message": "Missing required parameter" } }

List All Batches

curl https://api.doubleword.ai/v1/batches?limit=10 \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY"

Cancel Batch

curl https://api.doubleword.ai/v1/batches/batch-xyz789/cancel \ -X POST \ -H "Authorization: Bearer $DOUBLEWORD_API_KEY" Notes: Unprocessed requests are cancelled Already-processed results remain downloadable Cannot cancel completed batches

Processing Results

Parse JSONL output line-by-line: import json with open('results.jsonl') as f: for line in f: result = json.loads(line) custom_id = result['custom_id'] content = result['response']['body']['choices'][0]['message']['content'] print(f"{custom_id}: {content}")

Handling Partial Results

Check for incomplete batches and resume: import requests response = requests.get( 'https://api.doubleword.ai/v1/files/file-output123/content', headers={'Authorization': f'Bearer {api_key}'} ) if response.headers.get('X-Incomplete') == 'true': last_line = int(response.headers.get('X-Last-Line', 0)) print(f"Batch incomplete. Processed {last_line} requests so far.") # Continue polling and download again later

Retry Failed Requests

Extract failed requests from error file and resubmit: import json failed_ids = [] with open('errors.jsonl') as f: for line in f: error = json.loads(line) failed_ids.append(error['custom_id']) print(f"Failed requests: {failed_ids}") # Create new batch with only failed requests

Best Practices

Descriptive custom_ids: Include context in IDs for easier result mapping Good: "user-123-question-5" Bad: "1", "req1" Validate JSONL locally: Ensure each line is valid JSON before upload Split large files: Keep under 200MB limit Choose appropriate window: Use 24h for cost savings, 1h only when time-sensitive Handle errors gracefully: Always check error_file_id and retry failed requests Monitor request_counts: Track progress via completed/total ratio Save file IDs: Store batch_id, input_file_id, output_file_id for later retrieval
