# agent zero-trust policy change locked the agent itself out

## TL;DR

The policy change denied the agent's own access path, locking it out. Recover via break-glass access, fix the policy to include the agent's identity, and require policy simulations before applying. Policies need a 'does this lock me out' check.

agent zero-trust policy change locked the agent itself out
```

## Steps

1. Recover via break-glass: use the emergency access path to reach the policy console.
   Expected: Access is restored.

2. Fix the policy to explicitly allow the agent's identity/service token.
   Expected: The agent is admitted.

3. Verify the agent's workflows run again.
   Expected: The outage clears.

4. Add a pre-apply simulation: evaluate the policy against the agent's identity before saving.
   Expected: Self-lockouts are caught.

5. Require two-person review for policy changes affecting automation identities.
   Expected: The riskiest changes get eyes.

## When to use

- a policy change locks out automation
- the agent manages Zero Trust
- access dies right after a policy edit

## When not to use

- the lockout predates the change (different cause)
- the agent's credentials expired (check that separately)
- the policy is correct and the agent should not have access (then it is not a bug)

## Tool compatibility

- workerd
- Zero Trust policies

## Variant phrasings

- "zero trust policy locked out agent"
- "policy change locked out automation"
- "zero trust self lockout"

## Why it happens

Zero Trust policies are deny-by-default; an agent editing them can easily remove its own allow rule. The irony is structural: the thing most able to change the policy is the thing most hurt by a bad change. Simulation plus break-glass is the standard defense.

## Edge cases

- break-glass credentials need their own protection and testing
- the simulation must use the agent's real identity, not a test one
- the review needs someone who understands the automation's access needs
