flux-health

flux-health is a skill for Claude Code from tonone-ai/tonone. It costs 49 tokens per session (787 once invoked), scanned A, original, MIT.

A data-quality and pipeline-health checker that reviews whether data is fresh, whether its structure has changed, whether fields are missing, whether records are orphaned, and whether pipelines are running. A pipeline is an automated process that moves or transforms data.

In plain words
What is it for?
Use it to check table freshness, schema drift, null rates, orphaned records, pipeline status, monitoring setup, and warehouse or database health.
Why use it?
It helps identify stale or inconsistent data and broken processing before those problems reach reports or applications. It compares expected database structures with what is actually present.

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-health 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.

Data Quality and Pipeline Health

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 data stack:

  • Check for databases: ORM configs, connection strings, migration directories
  • Check for pipelines: Airflow DAGs, Dagster jobs, Prefect flows, dbt models, cron jobs
  • Check for data warehouses: BigQuery, Redshift, Snowflake configs
  • Check for monitoring: alerting configs, health check endpoints, dashboards
  • Identify what tables and pipelines exist

If the stack is ambiguous, ask the user.

Step 1: Check Data Freshness

For each key table or data source:

  • Find updated_at or equivalent timestamp columns
  • Query for the most recent record — how old is it?
  • Compare against expected freshness (real-time data should be minutes old, daily pipelines should be < 24h)
  • Flag anything stale

Step 2: Check Schema Drift

Compare actual schema against expected:

  • Read the ORM/migration-defined schema (the "expected" state)
  • Check for columns that exist in the database but not in code (added manually?)
  • Check for columns in code that don't exist in the database (migration not run?)
  • Check for type mismatches between ORM definitions and actual column types
  • Check for missing indexes that the schema defines

Step 3: Check Data Quality

Scan for common data quality issues:

  • Null rates on critical columns — columns that should never be null
  • Orphaned records — foreign key references to rows that don't exist
  • Broken foreign keys — if FK constraints are missing, check referential integrity manually
  • Duplicate records — rows that appear to be duplicates based on natural keys
  • Constraint violations — values outside expected ranges or enum sets

Step 4: Check Pipeline Status

For each pipeline or scheduled job:

  • Last successful run — when was it?
  • Last failure — when, and was it resolved?
  • Average duration — is it trending longer?
  • Error rate — how often does it fail?

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-health is a skill published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 9d ago), licensed MIT. It adds 49 tokens to every session and 787 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.
