data-quality-manager

data-quality-manager is an agent for Claude Code from revfactory/harness-100. It costs 31 tokens per session (687 once invoked), scanned A, original, Apache-2.0.

A data-quality manager defines and checks whether data is accurate, complete, consistent, timely, and shaped as expected. It profiles data, checks rules with tools such as Great Expectations or dbt, and watches for schema changes.

In plain words
What is it for?
Use it to measure nulls and distributions, define validation rules, detect schema drift, trace data through transformations, and monitor quality metrics against service targets.
Why use it?
Bad data can pass through a pipeline unnoticed and make reports, models, or business decisions unreliable. Automated checks and priority levels help teams detect and respond to important problems sooner.

About the project

Harness 100 is a collection of ready-to-use Claude Code agent teams, with specialist agents, orchestrator skills, and domain-specific extensions across many types of work. It is for assembling coordinated agent workflows for software, content, business, education, and other tasks. The catalogue entries are examples of the agents in this collection.

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

data-quality-manager 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 3d 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.

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.
