databricks-data-quality-observability

databricks-data-quality-observability is a skill for Claude Code from VincentChuWaiChow/vanguard-frontier-agentic. It costs 76 tokens per session (3,261 once invoked), scanned A, original, Apache-2.0.

A method for checking whether Databricks Lakeflow pipeline data quality is visible, measurable, and actionable. It reviews expectations, table constraints, monitoring, freshness, event logs, and quality agreements with data users.

In plain words
What is it for?
Use it to design or diagnose Lakeflow data-quality checks, monitor freshness and drift, inspect pipeline events, and define measurable quality SLAs.
Why use it?
It helps reveal missing values, duplicates, stale data, and pipeline failures before they mislead downstream users. It connects quality findings to evidence and agreed service levels.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 74
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

databricks-data-quality-observability 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 8d 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.

Purpose

This skill decides whether a Lakeflow pipeline's quality is visible, measurable, and actionable. Quality is verifiable only when expectations are declared with violation modes matching risk, table constraints are appropriate (enforced vs informational), Lakehouse Monitoring profiles the table and detects drift, freshness is monitored with a learned baseline, event logs are interrogated for lineage and results, quality SLAs are explicit and communicated to consumers, and quality evidence surfaces downstream.

When to use

  • A user is designing a Lakeflow pipeline and needs guidance on expectations (violation modes), table constraints, and Lakehouse Monitoring configuration.
  • A user is diagnosing unexpected data quality failures (missing nulls, unexpected duplicates, staleness) and needs to interrogate pipeline event logs and monitor metrics.
  • A user is defining a data quality SLA (e.g. 100% NOT NULL, 99% unique keys, freshness within 1 hour) and needs to verify it is monitorable and communicated to downstream consumers.
  • A user is implementing quality evidence surfaces for downstream data consumers and needs to decide what metrics/signals to publish.
  • A user is migrating quality logic from manual checks to Lakeflow expectations and needs to understand violation modes and their pipeline impact.

When NOT to use

  • No pipeline source, table schema, or quality audit plan is available — ask for the pipeline definition or a list of known quality issues rather than guessing.
  • The concern is pipeline structure, medallion layering, or table layout — route to databricks-lakeflow-pipeline-engineering-agent.
  • The concern is streaming state schema or checkpoint correctness → route to databricks-streaming-reliability-agent.
  • The concern is PII classification or data masking → route to databricks-data-protection-privacy-agent.
  • The concern is job or cluster operational reliability → route to databricks-platform-reliability-agent.
