Can you bypass AgentGuard's defenses?
AgentGuard is an AI agent firewall that blocks malicious requests through a two-stage defense pipeline. This repo is an open adversarial testing ground — submit attack payloads and see if they get through.
You (Attacker) AgentGuard (Defender)
───────────── ────────────────────
Submit payload ───────────────► Stage 1: Rule-based (11 checks)
in attacks/ Path traversal, SSRF, command injection,
header injection, payload regex, base64,
Unicode normalization, form-encoded, ...
───────────────► Stage 2: AI Judge
--backend gate → Trust Layer Gate API
--backend api → Ollama/vLLM/OpenAI-compatible
--backend mlx → Local mlx-lm (Apple Silicon)

BLOCKED or BYPASSED?

}# Stage 1 only (requires AgentGuard running on :10180)

# Both stages (recommended)
python eval/run_attacks.py --target all --backend gateRun the full 70-case evaluation set through the AgentGuard proxy for paper-grade results:
# Requires: AgentGuard running on :10180, Trust Layer API reachable
python eval/run_e2e_eval.py
# Custom test file or proxy
python eval/run_e2e_eval.py --test-file ~/trust-agent-guard-model/prompts/test_cases_v5.json
python eval/run_e2e_eval.py --proxy-url http://localhost:10180
python eval/run_e2e_eval.py --output results/e2e_v5_rank128.jsonThis sends all 70 test cases (18 benign + 52 attack/config) through the full pipeline: Stage 1 (rule engine) → Stage 2 (detect-route-judge via Trust Layer) → PASS/BLOCK.
Results are saved as JSON with per-category breakdown, FP/FN analysis, and latency stats.
Results are saved to results/ with a scoreboard showing which attacks bypassed which stage.

Files in benign/ are safe requests that overlap with attack patterns. These test that AgentGuard doesn't block legitimate developer workflows:
- Korean weather question, README read, coding questions
rm -rf ./node_modules,pip install,kubectl apply,docker build- SQL SELECT queries, API gateway configuration questions
Expected action: "pass". Any block = false positive.
A macOS LaunchAgent runs a full attack/defense cycle every 6 hours:
- Pull latest AgentGuard and rebuild binary
- Start proxy, run all attacks + benign tests
- Generate 2 new attack variations + 1 new benign scenario (via Claude Code)
- Commit results and new scenarios, create PR
- If bypasses found, create defense PRs on related repos
# Manual run
./scheduler/run_cycle.sh
# LaunchAgent (auto, every 6 hours)
cp scheduler/com.agentguard.redteam.plist ~/Library/LaunchAgents/
launchctl load ~/Library/LaunchAgents/com.agentguard.redteam.plist
# Check logs
cat /tmp/redteam-cycle-*.log- One attack per file — each JSON file in
attacks/is a single attack scenario - Explain why —
why_dangerousfield must describe the real-world risk - No DoS — compression bombs, infinite loops, or resource exhaustion attacks are out of scope
- Responsible disclosure — if you find a bypass that works against the latest AgentGuard, open a PR here (not a public issue on the main repo)
- Fair game — Unicode tricks, encoding chains, semantic attacks, multi-step chains, social engineering, prompt injection — all welcome
- Fork this repo
- Add your attack JSON files to
attacks/ - Run
python eval/validate.pyto check your format - Open a PR with your attacks
Every merged attack that bypasses AgentGuard will be credited in the scoreboard and used to improve defenses.
When AgentGuard patches a bypass found here, the attack file gets a patched field:
{
"patched": {
"version": "0.1.6",
"date": "2026-03-22",
"fix": "Added safe command allowlist in Stage 1"
}
