An AI coding agent or autonomous workflow is a non-human identity that follows instructions found in text it reads. Treat it like a new contractor with a laptop: useful, fast, and able to be tricked. Quick check for any agent deployment: Which identity does it use? What can that identity do if the agent is tricked? How would I notice, and how fast can I turn it off?

Zero Trust for AI agents and automation (principles 11 and 12)

An AI coding agent or autonomous workflow is a non-human identity that follows instructions found in text it reads. Treat it like a new contractor with a laptop: useful, fast, and able to be tricked.

ControlWhat to do
Own identityGive each agent or workflow its own account or token. Never reuse a person's login or a shared admin key. The audit log must show which agent did what.
Least privilegeRead-only by default. Grant write access per task and per repository or resource. Prefer deny-by-default tool lists and file/folder scopes.
Short-lived credentialsIssue tokens that expire in minutes or hours (OIDC federation, vault leases). No long-lived keys in agent environments or prompts.
Just-in-time approvalRequire a human approval step for destructive or irreversible actions (delete, deploy to production, send money or mail, change permissions).
Isolation (assume breach)Run agents in a sandbox or disposable container with no access to production secrets, no broad network egress, and a throwaway workspace. A prompt injection should have a small blast radius.
Network and egressAllow-list the domains an agent can reach. Block cloud metadata endpoints from agent workloads.
Untrusted inputTreat web pages, issues, emails, documents and tool outputs as data, not instructions. Do not let an agent forward secrets or run commands because retrieved text said so.
Secrets hygieneKeep secrets out of prompts, transcripts and logs. Mask them in saved transcripts; rotate any that appeared in one.
LoggingLog every tool call with agent identity, arguments (secrets masked), result status and time, to a store the agent cannot edit.
MonitoringAlert on an agent acting outside its pattern: new resource types, unusual hours, bulk reads, permission changes, repeated denied actions, new outbound domains.
Kill switchBe able to revoke one agent's credentials in one step, and a runbook that says how.

Quick check for any agent deployment: Which identity does it use? What can that identity do if the agent is tricked? How would I notice, and how fast can I turn it off?

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.
