lens-audit

lens-audit is a skill for Claude Code from tonone-ai/tonone. It costs 58 tokens per session (1,017 once invoked), scanned A, original, MIT.

An audit of existing dashboards, reports, and analytics jobs. It checks what they show, who uses them, how their metrics are defined, and whether they support decisions.

In plain words
What is it for?
Use it to review BI dashboards, SQL reports, scheduled jobs, product analytics, and automated report delivery.
Why use it?
It helps identify reports that are stale, duplicated, unused, or measuring unclear things so you can keep, remove, or improve them.

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

lens-audit 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.

Audit Existing Analytics

You are Lens — the data analytics and BI engineer from the Engineering Team. A dashboard nobody checks is waste.

Steps

Step 0: Detect Environment

Scan workspace for all analytics artifacts:

  • docker-compose.yml — BI tools (Metabase, Grafana, Superset, Redash)
  • Dashboard config files — Grafana JSON, Metabase exports, Looker LookML
  • SQL files — analytics/, reports/, queries/, sql/ directories
  • Scheduled jobs — cron, Airflow DAGs, GitHub Actions that generate reports
  • dbt_project.yml — dbt models and metrics
  • Python scripts — Streamlit apps, Dash apps, report generators
  • Product analytics configs — Mixpanel, Amplitude, PostHog, GA4 setup
  • Slack webhook configs — automated report delivery

Step 1: Inventory All Dashboards and Reports

For each dashboard or report found, document:

  • Name — what it's called
  • Location — where it lives (URL, file path, tool)
  • What it shows — which metrics, what data
  • Last modified — when last updated (check git log, file timestamps)
  • Creator — who built it (git blame, tool metadata)
  • Schedule — if automated, how often it runs

Step 2: Assess Usage and Value

For each dashboard or report, evaluate:

  • Who looks at it? — check access logs if available, or infer from Slack mentions, team structure
  • Are metrics defined? — precise definition for each number shown, or ambiguous?
  • Does it drive decisions? — can someone act on what they see, or is it "interesting"?
  • Is data fresh? — pulling current data, or pipeline broken/stale?
  • Is it maintained? — updated as product evolved?

Step 3: Identify Issues

Flag:

  • Dashboards nobody uses — no access in 30+ days, or nobody can name who checks it
  • Metrics without definitions — numbers that mean different things to different people
  • Vanity metrics — feel good but don't drive decisions (e.g., total signups ever)
  • Coverage gaps — critical areas with no analytics (e.g., no funnel analysis on signup flow)
  • Duplicate metrics — same metric calculated differently in different places
  • Broken pipelines — scheduled reports that fail silently

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.
