# AgentEval

**Red-team and stress-test your conversational AI agent before your customers do.**

AgentEval generates adversarial synthetic customers and targeted safety attacks for your domain, runs real multi-turn conversations against your agent, and has a judge model tell you exactly where it broke, ranked by severity. Run it from your terminal, gate your CI on it, or use it in the browser.

AgentEval 1.0.0 · Demo banking agent · target: http http://localhost:9000/chat

  ✓ The Calm Balance Checker

```

## Why

Agents pass their QA test cases and then fail in production on the customer nobody thought to test: the fraud victim who says "my card is blocked" instead of "fraud", the caller who changes their mind halfway through, the "auditor" who talks the agent into reading out someone else's address. AgentEval writes those customers for you.

Three suites:

| Suite | What it finds |
|---|---|
| **Wind Tunnel** (operational) | Wrong routing, context drift, PII leaks, false confidence, missing escalation, hallucinated tools/data. Personas span four risk tiers (baseline → edge case → high risk → critical), and the judge flags the failures you **likely never wrote a test for**. |
| **Red Team** (safety) | Seven attack categories: jailbreak, harmful content, bias, PII leakage, scope violation, prompt injection, manipulation compliance. |
| **Accent & Language** | Whether every caller gets the same service. Each customer need runs in plain English (the control), in different accents, code-switched (Hinglish, Spanglish, Tanglish, Taglish), and through simulated speech-to-text noise. One judge compares them all. |

Real finding from testing: a banking agent advised a customer to space out large transfers to reduce scrutiny. That's a compliance failure no happy-path test would catch.

---

## Quickstart (2 minutes)

```bash
pip install "agenteval-cx[google]"    # or the latest from GitHub: "agenteval-cx[google] @ git+https://github.com/akshaynara/agenteval"
export ANTHROPIC_API_KEY=sk-ant-...     # or GEMINI_API_KEY (free key: aistudio.google.com/apikey) + `name: gemini`

agenteval demo-agent &      # a banking agent with 4 bugs planted on purpose
agenteval init              # writes agenteval.yaml, pointed at the demo agent
agenteval run
```

Then point `target.url` in `agenteval.yaml` at your own agent.

A run of ~15 cases costs roughly $1–2 in API usage: a fast, cheap model generates and plays the customers; a stronger model judges.

---

## Connect your agent

| `target.type` | For | Each turn sends |
|---|---|---|
| `http` | Your agent behind any JSON endpoint | The conversation so far |
| `openai` | Any OpenAI-compatible `/chat/completions` (OpenAI, Azure, vLLM, LiteLLM, Ollama) | The conversation so far |
| `cx_agent_studio` | A Google CX Agent Studio app (`runSession`) | The latest message, in a fresh session per customer |
| `dialogflow_cx` | A Dialogflow CX agent (`detectIntent`) | The latest message, in a fresh session per customer |
| `simulated` | No endpoint yet: the model plays your agent from its system prompt | — |

Every test conversation gets its own session, and the run checks your agent answers before spending any tokens.

### `http`

AgentEval sends your agent the conversation so far and reads its reply:

```http
POST /chat
{"messages": [{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}, ...]}

→ {"reply": "..."}
```

Different shape? Configure it:

```yaml
target:
  type: http
  url: https://my-agent.example.com/v1/chat
  reply_field: choices.0.message.content   # dotted path into the JSON response
  headers:
    Authorization: "Bearer ${AGENT_TOKEN}"  # any ${ENV_VAR}, or ${ENV_VAR:-default}
  body:                                     # extra fields sent with every request
    channel: web
  session_field: session_id                 # optional: a fresh id per test conversation
  timeout: 30
```

### Google CX Agent Studio and Dialogflow CX

```bash
pip install "agenteval-cx[google]"
gcloud auth application-default login   # or set target.access_token
```

```yaml
target:
  type: cx_agent_studio
  app: projects/MY_PROJECT/locations/us/apps/MY_APP_ID
  use_tool_fakes: true          # tools return their fakes: attack the agent without touching real systems
  # deployment: DEPLOYMENT_ID   # entry_agent: AGENT_ID   # quota_project: BILLING_PROJECT

# or
target:
  type: dialogflow_cx
  agent: projects/MY_PROJECT/locations/global/agents/AGENT_ID
  environment: prod             # default: draft
  language_code: en
```

The judge also sees what the platform reported for each turn (matched intent and confidence, page, tool calls), which the simulated customer never sees. That's how a fraud report quietly routed to *Card Activation* gets caught even when the agent's words sound fine. When the agent ends the session, the conversation ends too.

### `openai`

```yaml
target:
  type: openai
  base_url: http://localhost:11434/v1
  model: llama3.2
  api_key_env: OPENAI_API_KEY   # optional, sent as a Bearer token
  system_prompt: You are the support assistant for ...
```

**No endpoint yet?** Test the system prompt itself; the simulator model plays your agent:

```yaml
target:
  type: simulated
  system_prompt_file: prompts/agent.md
```

---

## Configuration

Everything lives in `agenteval.yaml` (`agenteval init` writes a commented starter):

```yaml
name: My agent
domain: "Banking — Fraud & Card Services"   # be specific: it shapes every persona and attack

target: { type: http, url: http://localhost:9000/chat }

provider:
  name: anthropic            # reads ANTHROPIC_API_KEY (override with api_key_env)
  models:                    # optional; one model per role
    generator: claude-haiku-4-5-20251001
    simulator: claude-haiku-4-5-20251001
    judge: claude-sonnet-4-6

suites:
  wind_tunnel: { enabled: true, personas: 8, turns: 4 }
  red_team:    { enabled: true, probes: 7, turns: 4, categories: [jailbreak, pii_leakage, prompt_injection] }

run:
  concurrency: 4             # conversations in parallel
  fail_on: high              # critical | high | medium | low | none
  output: agenteval-report.json
```

### Providers

| `provider.name` | Key | Default models (generator / simulator / judge) |
|---|---|---|
| `anthropic` | `ANTHROPIC_API_KEY` | Haiku 4.5 / Haiku 4.5 / Sonnet 4.6 |
| `gemini` | `GEMINI_API_KEY` (or `GOOGLE_API_KEY`), free tier available | Gemini 3.8 Flash for all three |

Gemini can also run on **Vertex AI** with your Google Cloud credentials: `vertexai: true`, `project`, `location`. Its thinking depth per role is set with `thinking: {judge: high}`.

**Cross-model judging.** Let one model family attack and another grade, so no model marks its own homework:

```yaml
provider:
  name: gemini               # writes and plays the customers and attackers
  judge:
    name: anthropic          # grades the transcripts
    model: claude-sonnet-4-6
```

See [`examples/`](examples/) for ready-made configs: the demo agent, a prompt-only agent, CX Agent Studio, Dialogflow CX, and an OpenAI-compatible endpoint.

## Accent & language testing

Voice and global agents fail people who don't sound like the test script. For each scenario, AgentEval runs the same need several ways and one judge compares every variant against the plain-English control:

| Variant | Example |
|---|---|
| Control | "I did not make the fifteen dollar payment on my card yesterday" |
| Indian English | "Yesterday's fifteen dollar payment on my card, I have not made it only" |
| Hinglish | "Mera card pe kal fifteen dollar ka payment hua, maine nahi kiya" |
| Voice, Indian English | "i did make the fifty dollar payment on my card yesterday" — speech-to-text dropped *not* and misheard *fifteen* |

```yaml
suites:
  language:
    enabled: true
    scenarios: 3
    accents: [indian_english, british_english, american_english]   # any name works, e.g. scottish_english
    code_switch: [hinglish]                                          # spanish_english, tanglish, taglish
    asr: [indian_english]
```

Each scenario gets a **consistency score** (0–100) and a **bias** flag when the accent or language itself changed how well or how respectfully the caller was treated. Speech-to-text noise is seeded, so a rerun applies exactly the same errors. Run just this suite with `agenteval run --suite language`.

---

## Regression mode and shareable reports

Found something, fixed your agent? Replay the exact same test cases and see what changed:

```bash
agenteval run -o before.json                  # find the failures
# ...fix your agent...
agenteval run --baseline before.json --html after.html
```

```text
╭─ vs baseline · 2026-11-03T09:12:44+00:00 ─╮
│ 4 fixed   0 regressed   1 still failing   │
╰───────────────────────────────────────────╯
```

`--baseline` reuses the saved personas, probes and scenarios instead of generating new ones, so the comparison is like for like. The gate fails if anything that passed before fails now (`run.fail_on_regression`). Opening messages replay exactly; the simulated customer's follow-ups are generated fresh, so re-run a case that flips before treating it as a real change.

`--html report.html` (or `run.html` in the config) writes a single self-contained file: the summary, the before/after table, and every failure with its transcript, filterable and printable, in light and dark mode. Email it, attach it to a PR, or put it on screen. `agenteval show report.json --html report.html` converts any saved run, and `agenteval compare before.json after.json` diffs two runs.

---

## CLI

| Command | |
|---|---|
| `agenteval init` | Write a starter `agenteval.yaml` |
| `agenteval run [config]` | Run the suites. `--suite wind-tunnel\|red-team\|language`, `--personas N`, `--probes N`, `-c N`, `--fail-on LEVEL`, `-o report.json`, `--html report.html`, `--baseline before.json`, `--transcripts`, `--markdown summary.md` |
| `agenteval show [report.json]` | Re-print a saved report (`--transcripts`, `--markdown`, `--html out.html`) |
| `agenteval compare before.json after.json` | Fixed / regressed / still failing. Exits 1 if anything regressed |
| `agenteval serve` | Web UI + API on http://127.0.0.1:8000 |
| `agenteval demo-agent [--fixed]` | The buggy banking agent on http://127.0.0.1:9000/chat (`--fixed`: same agent, bugs fixed) |

Exit codes: `0` gate passed · `1` gate failed · `2` config/usage error · `3` run error.

---

## Run it in CI

```yaml
# .github/workflows/agenteval.yml in your agent's repo
on: pull_request
jobs:
  agenteval:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: akshaynara/agenteval@v1
        env:
          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
```

The job fails when any finding is at or above `fail_on`, or (with `baseline:`) when anything regressed. The Markdown summary appears on the job page, and the JSON and HTML reports are uploaded as an artifact. Inputs: `config`, `suite`, `fail-on`, `baseline`, `html`, `args`. See [`action.yml`](action.yml) and [`examples/github-actions.yml`](examples/github-actions.yml).

Not on GitHub? `agenteval run` exits `1` when the gate fails, so it works in any CI.

---

## Web UI

`agenteval serve` runs the same engine in your browser, with live streaming results. The hosted version is at [try-agenteval.netlify.app](https://try-agenteval.netlify.app): bring your own Claude or Gemini key (a free Gemini key works). It's used for that run only and never stored.

Docker:

```bash
docker build -t agenteval .
docker run -p 8000:8000 agenteval                                       # web UI
docker run -v "$PWD:/work" -e ANTHROPIC_API_KEY agenteval run            # CLI
```

```

### Deploying the hosted version

- **API on Render:** the existing service config keeps working (root `backend`, build `pip install -r requirements.txt`, start `uvicorn app.main:app --host 0.0.0.0 --port $PORT`); `backend/` now just installs this package. Simpler new setup: root `.`, build `pip install .`, start `agenteval serve --host 0.0.0.0 --port $PORT`.
- **UI on Netlify:** publish `frontend/`. On a `*.netlify.app` host it calls the Render API; served by `agenteval serve`, it calls its own origin.
- Lock CORS down with `AGENTEVAL_CORS_ORIGINS=https://your-site.netlify.app`.
