Use when reviewing a codebase, feature, or data flow for privacy issues — unnecessary data collection, missing consent, third-party trackers, or logs that shouldn't exist.

5 rules. About 0 are common, 5 are distinctive, and 0 are very specific to this project.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Privacy Review

When to Use

  • The user asks for a privacy review before shipping a feature
  • Reviewing code that collects, stores, logs, or transmits user data
  • Auditing third-party SDKs/scripts added to a project

Instructions

Run this as a short checklist — keep it fast, not exhaustive prose.

  1. Data minimization: for each piece of user data collected, confirm it is actually used for a stated purpose. Flag anything collected "just in case."
  2. Logging: check whether logs capture anything sensitive — emails, IPs tied to identity, auth tokens, full request/response bodies on user-data endpoints. Logs are a common accidental leak point.
  3. Consent: if data collection falls into a category that typically needs consent (analytics, marketing, location, biometric, third-party sharing), confirm a consent step exists before collection, not after.
  4. Third parties: list every third-party SDK/script/pixel present and what data each can access. Flag any with broad access (e.g., a full-page tracking script) relative to its stated purpose.
  5. Retention: check whether there's any defined deletion/retention policy for collected data, or whether it's kept indefinitely by default.
  6. Sharing boundary: confirm user data isn't sent to a third-party endpoint as a side effect of an unrelated feature (e.g., an analytics call that accidentally includes a full user object).
  7. Output findings as a short checklist with ✅ / ⚠️ / ❌ per item — don't write paragraphs per point.

Examples

User: "Can you do a quick privacy pass on our signup flow before we launch?" Agent should: Check what fields are collected and whether all are necessary, whether the analytics call sends more than needed, whether a privacy policy/consent checkbox exists, and return a short ✅/⚠️/❌ checklist — not a long essay.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
