What it does
Lens Audit is an agent skill from jeremylongshore/tons-of-skills-marketplace. Review existing analytics — find all dashboards and reports, check who uses them, whether metrics are defined, and whether they drive decisions. Recommend what to keep, kill, or add. Use when asked "are our dashboards useful", "analytics review", or "metrics audit".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).
It sits in Data & Analytics. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Asked are our dashboards useful
- Analytics review
Example prompts
- “are our dashboards useful”
- “analytics review”
- “metrics audit”
- “/lens-audit”
Requirements
- Python 3
- Docker
- Pre-approved tools (allowed-tools): Read, Bash, Glob, Grep, WebFetch, WebSearch, AskUserQuestion
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashGlobGrepWebFetchWebSearchAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Lens Audit loads about 1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 369 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash, Glob, Grep, WebFetch, WebSearch, AskUserQuestion
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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?
Show full SKILL.md (148 more words)Show less
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
Step 4: Present Audit Results
Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.
## Analytics Audit
**Dashboards found:** [N] | **Reports found:** [N] | **Active:** [N] | **Stale:** [N]
### Inventory
| Name | Tool | Last Modified | Used By | Verdict |
|------|------|--------------|---------|---------|
| [name] | [Metabase/Grafana/etc] | [date] | [who/nobody] | [keep/kill/update] |
| ... | ... | ... | ... | ... |
### Issues Found
- [N] dashboards with no recent access — candidates for removal
- [N] metrics without clear definitions
- [N] vanity metrics that don't drive decisions
- [coverage gap] — [critical area with no analytics]
### Recommendations
**Keep** (valuable, maintained):
- [dashboard] — [why it's valuable]
**Kill** (unused, stale, or misleading):
- [dashboard] — [why: no users / broken data / vanity metric]
**Update** (valuable concept, needs work):
- [dashboard] — [what needs fixing]
**Add** (missing coverage):
- [area] — [why it matters, what to measure]Be direct about what to kill. Fewer, better dashboards beat many neglected ones.
Delivery
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
