Reviews authorization, tenant isolation, roles, ownership, row access, admin boundaries, sharing, and privilege escalation.

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Check object ownership, tenant scoping, bulk operations, admin bypasses, background jobs, and indirect object references.

    line 14
  2. Distinctive:

    Do not accept UI-only hiding as authorization.

    line 30

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 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.

Keep what fits and drop the rest. Your version, ready for your agents.

Authz Boundary Review

Review access-control boundaries as behavior, not style.

Workflow

  1. Identify actors, roles, tenants, objects, and privileged actions.
  2. Trace request/input to authorization decision and data access.
  3. Check object ownership, tenant scoping, bulk operations, admin bypasses, background jobs, and indirect object references.
  4. Validate with tests or concrete code evidence.
  5. Report exploit path and minimal fix.

Output

  • affected boundary
  • attacker capability
  • missing or weak control
  • exploit path
  • files and lines
  • regression test suggestion

Rule

Do not accept UI-only hiding as authorization. The enforcing control must exist on the server or trusted boundary.

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.
