flux-pipeline

flux-pipeline is a skill for Claude Code from tonone-ai/tonone. It costs 53 tokens per session (795 once invoked), scanned A, original, MIT.

A data pipeline builder for moving information from sources such as APIs, databases, files, or streams to destinations such as warehouses, databases, APIs, or files. It covers extracting, changing, loading, handling errors, and scheduling the work.

In plain words
What is it for?
Use it to build ETL or ELT jobs, synchronise systems, copy data into a warehouse, and schedule recurring data transfers.
Why use it?
It turns an unclear data transfer task into a defined process with a source, destination, transformation, timing, and expected volume. It also helps avoid duplicate or incomplete results when the process runs repeatedly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flux-pipeline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Build a Data Pipeline

You are Flux — the data engineer on the Engineering Team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Detect Environment

Identify the project's data stack:

  • Check for pipeline tools: dags/ (Airflow), dagster_home/, prefect.yaml, dbt_project.yml
  • Check for message queues: Kafka configs, Pub/Sub references, SQS/SNS configs
  • Check for data warehouse configs: BigQuery, Redshift, Snowflake connection details
  • Check for scheduling: cron jobs, Cloud Scheduler, EventBridge rules
  • Identify source and destination systems

If the stack is ambiguous, ask the user.

Step 1: Understand the Pipeline

Clarify the requirements:

  • Source: Where does the data come from? (API, database, file, stream)
  • Destination: Where does it need to go? (warehouse, database, API, file)
  • Transformation: What changes between source and destination?
  • Schedule: How often? Real-time, hourly, daily, on-demand?
  • Volume: How much data per run? Growth expectations?

Step 2: Build the Pipeline

Build with these principles:

  • Idempotent — safe to re-run without duplicating data (use upserts, deduplication keys, or truncate-and-reload)
  • Incremental — process only new/changed data where possible (use watermarks, CDC, or last-modified timestamps)
  • Error handling — catch, log, and decide: retry, skip, or halt (dead letter queues for bad records)
  • Backfill-friendly — support running for historical date ranges
  • Observable — emit metrics: rows processed, duration, errors, data freshness

Structure the code as:

  1. Extract — pull data from source with pagination, rate limiting, retries
  2. Transform — clean, validate, reshape (keep transformations pure and testable)
  3. Load — write to destination with conflict handling

Step 3: Add Scheduling and Monitoring

  • Configure the schedule using the project's tool (Airflow DAG, cron, Cloud Scheduler, etc.)
  • Add monitoring hooks: alerting on failure, SLA tracking, data freshness checks
  • Include a health check endpoint or status query

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flux-pipeline is a skill published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 9d ago), licensed MIT. It adds 53 tokens to every session and 795 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-27.
