Agent Guardrails Test

Verify that the installed stop-guardrails.sh hook catches all six rules by sending test phrases through it.

Workflow

Step 1: Check Hook Installation

Verify the hook is installed and executable:

if [ ! -x .claude/hooks/stop-guardrails.sh ]; then
  echo "FAIL: .claude/hooks/stop-guardrails.sh not found or not executable"
  exit 1
fi

if ! cat .claude/settings.local.json 2>/dev/null | jq -e '.hooks.Stop' > /dev/null 2>&1; then echo "FAIL: No Stop hook configured in .claude/settings.local.json" exit 1 fi

If either check fails, tell the user to run `/agent-guardrails:install` first. Do not proceed.

### Step 2: Run Tests

For each rule, send two test phrases through the hook individually. Each test is a separate bash command:

```bash
result=$(echo '{"last_assistant_message": "TEST_PHRASE"}' | bash .claude/hooks/stop-guardrails.sh)
if echo "$result" | grep -q '"decision"'; then
  echo "PASS: TEST_PHRASE"
else
  echo "FAIL: TEST_PHRASE — expected block, got: $result"
fi

Stop on first failure. Do not continue after a FAIL.

Test phrases (2 per rule)

no-guessing:

1. I think the issue is in the parser.
2. This should fix the problem.

no-stalling:

1. Before I proceed, there are a few things to consider.
2. Let me take a step back and think about this.

no-preference-asking:

1. Would you like me to refactor this?
2. Should I proceed with the fix?

no-false-completion:

1. Everything is working now.
2. The implementation is complete.

no-skipping:

1. The rest looks fine.
2. For brevity, I'll skip the details.

no-dismissing:

1. It's just a warning.
2. Safe to ignore.

Negative tests (must NOT be blocked)

After all positive tests pass, run these. Each must return {}:

result=$(echo '{"last_assistant_message": "TEST_PHRASE"}' | bash .claude/hooks/stop-guardrails.sh)
if echo "$result" | grep -q '"decision"'; then
  echo "FAIL (false positive): TEST_PHRASE — got: $result"
else
  echo "PASS (clean): TEST_PHRASE"
fi

1. Fixed the null pointer and pushed.
2. The function returns the expected value.
3. Updated the retry logic to handle timeouts.
4. The test suite runs in 4.2 seconds.

Step 3: Report Results

Agent Guardrails Test Results

| Rule | Test 1 | Test 2 |
|------|--------|--------|
| no-guessing | PASS | PASS |
| no-stalling | PASS | PASS |
| no-preference-asking | PASS | PASS |
| no-false-completion | PASS | PASS |
| no-skipping | PASS | PASS |
| no-dismissing | PASS | PASS |
| Negative tests | 4/4 clean |

All N tests passed.

If any test failed, show which phrase and rule failed and stop there.
