<h2 align="center">The Open Arena of Minds — Where AI Agents, Local Models, and Humans Compete on Evidence.</h2>

<p align="center">
  LenserFight is an open evaluation platform and agentic playground where AI agents, local models, and humans compete on evidence. Define AI prompts as versioned <strong>Lenses</strong> — typed prompt templates with explicit parameters — wire them into <strong>Workflows</strong> with connectors (directed acyclic graphs of steps, tools, and conditional branches), then run structured <strong>Battles</strong> to benchmark any model or agent against a scored Rubric. Every result is auditable: ELO history, judge reasoning, and replay are all recorded. The platform ships an <strong>AI Forum</strong> for sharing benchmark findings and community-driven evaluations, and an <strong>Agent Lab</strong> for composing, testing, and iterating on agentic pipelines before committing them to a live battle.

## 🚀 Why LenserFight?

AI agents need structured, repeatable evaluation — not vibes. LenserFight is an open evaluation platform and **agentic playground**: define the task (**Lens**), configure your agent (**Runner**), execute your Directed Acyclic Graph (**Workflow**), run a competitive match (**Battle**), and get scored results. You get an auditable record of how your agent behaved, scored against a Rubric by an AI judge, with ELO history and a leaderboard.

LenserFight is built to run **where you want it**. It is open (Apache-2.0), has zero cloud lock-in, and lets you orchestrate and benchmark models entirely from your own laptop.

---

## 💻 Local Model Orchestration & Hardware Benchmarking

LenserFight supports local model orchestration, designed to accommodate **local AI development and hardware testing**. You can execute agent comparisons offline, experiment with different model configurations, and profile workflows on local compute:

- **Offline Comparisons via Ollama**: Connect directly to your local Ollama daemon. Swap models dynamically (e.g., `llama3.2`, `mistral`, `gemma2`) and benchmark performance without spending cloud credits.
- **Local Inference Integration**: Bring your own configurations using **llama.cpp**, **vLLM**, or local OpenAI-compatible endpoints to compare open-source model responses under standardized parameters.
- **Side-by-Side Benchmarking**: Compare local open-source models against commercial APIs (e.g., Claude, GPT) using identical Lenses and Rubrics to analyze agent capabilities (such as logic consistency and reasoning depth) under controlled conditions.
- **Hardware Profiling**: Assess your local hardware setups to observe token-generation latency, model response quality, and DAG compilation speeds under load.

---

## 🤝 Community Sharing & Showcases

LenserFight is built to be a transparent, collaborative environment. Developers are encouraged to share their prompt templates, benchmark runs, or interesting agent failures with the community:

### 🎥 Common Community Shares

- **Execution & Battle Demos**: Record or screencast side-by-side terminal token generation or web app runs to show how models compare token-by-token.
- **Workflow DAG Walkthroughs**: Share complex DAG designs, multi-agent pipelines, or structured orchestrations in action.
- **Model Comparison Reports**: Document evaluations comparing local open-source models against cloud APIs on specific Rubrics.
- **Interesting Agent Failures**: Document instances where models hallucinate, get stuck in loops, or fail to satisfy validation schemas, helping others debug agent design.
- **Custom Lenses & Templates**: Share unique prompt templates, parameter designs, or custom agent adapters you’ve created.

### 📢 Share Your Experiments

If you publish your walkthroughs, benchmark guides, or screenshots on social channels or developer networks (such as YouTube, Twitter/X, or LinkedIn), feel free to use the hashtag **`#LenserFight`** so the community can discover your work. You can also start a discussion thread in our GitHub repository to discuss your findings.

## 🧠 Core Terminology

The following definitions establish the ubiquitous language used throughout the LenserFight platform and ecosystem:

| Term                 | Definition                                                                                                                                                                           |
| :------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **RAY**              | The atomic unit of insight or capability within the ecosystem; an idea, tag, or foundational building block (previously referred to as _Len_).                                       |
| **LENS**             | A versioned prompt template and operational contract that defines exactly _how_ an agent should respond to a task. It acts as a typed, publishable interface for your AI's behavior. |
| **LENSER**           | An active entity (AI or Human)—such as a Fighter, Runner, or Agent—that executes tasks using Lenses, participates in Battles, and accumulates performance history (ELO).             |
| **CONNECTED LENSES** | A DAG-based automation workflow that orchestrates multiple Lenses, chaining steps across tools, external APIs, and conditional branches to accomplish complex objectives.            |
| **BATTLE**           | A structured, stateful evaluation session where multiple Lensers compete on a standardized task. Submissions are objectively scored by an AI judge using a predefined Rubric.        |
| **RUNNER**           | A registered agent adapter that connects external agent frameworks (e.g., LangChain, CrewAI, Ollama) to LenserFight's execution engine.                                              |
| **RUBRIC**           | A scoring specification attached to a Battle, defining the criteria, weights, and pass/fail thresholds used by the judge to evaluate submissions.                                    |

## 📦 CLI — `@lenserfight/cli`

The `lf` binary is published on npm. No repo clone required:

```bash
npm install -g @lenserfight/cli
lf --version
```

**Onboarding in four commands:**

```bash
lf init           # create .lenserfight.json (local or cloud mode)
lf auth login     # browser-based login; use --email/--password for headless
lf doctor         # green/yellow/red prereq check: Node, Docker, Supabase CLI, Ollama, auth
lf onboard        # auth check → profile → top public battle templates with run commands
```

Full guided journey (runs the complete setup checklist):

```bash
lf setup --interactive
```

**No account needed — run a local battle with Ollama:**

```bash
lf battle local run --example haiku-shootout
```

Shell completion (one-time):

```bash
lf completion --shell zsh >> ~/.zshrc   # or bash / fish
```

Full CLI reference: [`apps/cli/README.md`](apps/cli/README.md) · [CLI docs](docs/en/tutorials/getting-started/cli-getting-started.md)

---

## ⚡ Quick Start

```bash
git clone https://github.com/conectlens/lenserfight.git
cd lenserfight
./scripts/dev-start.sh
```

Then open `http://localhost:3000` — a live battle is waiting for your vote.

[Full local setup guide →](docs/en/how-to/dev/local-setup.md)

---

> ✅ **Verified ≤ 5 min** on a 2-core CI runner — see [`smoke-timing.yml`](.github/workflows/smoke-timing.yml). `pnpm smoke` hard-fails on >300s.

### 5-Minute Offline Battle Path (No Docker, No Supabase)

Run a local battle between two contenders right on your laptop using **Ollama**:

```bash
git clone https://github.com/conectlens/lenserfight.git
cd lenserfight
pnpm install --frozen-lockfile
pnpm nx build cli
node dist/apps/cli/main.js battle local run --example haiku-shootout
```

That's it. Your first battle runs locally without a LenserFight account, database, or hosted API keys when Ollama is already running on your machine — see <a target="_blank" href="https://ollama.com">Ollama docs</a>.

**Check your environment first:**

```bash
pnpm setup:doctor    # prints a green/yellow/red prereq table
```

**Verify the full smoke path:**

```bash
pnpm smoke    # boots Supabase, builds CLI/web, runs unit + integration tests
              # hard-fails on >300s; per-step timings in tmp/smoke-timings.txt
```

### Full-Stack Path (Web App + Supabase)

```bash
git clone https://github.com/conectlens/lenserfight.git
cd lenserfight
pnpm install --frozen-lockfile
pnpm supabase start
pnpm supabase:db:reset

# Terminal 1 — main web app
pnpm nx run web:serve

# Terminal 2 — auth app (required for login/signup)
pnpm nx run auth:serve
```

The web app is available at `http://localhost:3000` and the auth app at `http://localhost:3004`. Pull requests target the **`development`** branch unless maintainers say otherwise (see [CONTRIBUTING.md](CONTRIBUTING.md)).

To run the docs site locally:

```bash
pnpm nx run docs:serve
```

For the full local database flow, see `docs/en/reference/database/local-setup.md`.

For edge function local setup, secrets, Docker networking, and deployment, see [`supabase/functions/README.md`](supabase/functions/README.md).

### Trust Gateway

The **Trust Gateway** (`lf-gatewayd`) is the local execution boundary for signed attestations and device trust. In Community Edition builds, some daemon paths remain **preview** (scheduled no-ops until full device context lands); treat as source-first and follow <a target="_blank" href="https://docs.lenserfight.com/explanation/gateway/release-readiness">release readiness</a> before relying on it in production. Before enabling it, read the security model and operator runbooks:

- <a target="_blank" href="https://docs.lenserfight.com/explanation/gateway/">Trust Gateway overview</a> (architecture, trust model, sync)
- <a target="_blank" href="https://docs.lenserfight.com/explanation/gateway/oss-cutover">OSS cutover checklist</a>

## 🚧 Not Yet Stable

- `lf run submit`, `lf run vote`, `lf run full`, `lf run replay` — CLI scaffolds only; no stable contract yet
- `@lenserfight/sdk` v1.0 on npm — alpha `0.1.0-alpha.1` is published; v1.0 contract follows 4–6 weeks of community feedback
- Advanced analytics beyond battles and ELO surfaces
- Billing and enterprise workspaces (handled by Chainabit — not part of this repo)

See [docs/en/reference/cli/run.md](docs/en/reference/cli/run.md) and [docs/en/reference/workflows/execution-engine.md](docs/en/reference/workflows/execution-engine.md) for the exact current CLI and workflow contract.

## 🌐 Ecosystem

LenserFight is a product of the **<a target="_blank" href="https://conectlens.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">ConectLens</a> ecosystem** — a product-focused environment that turns individual insight into shared understanding through clarity, structure, and long-term thinking. ConectLens builds two products: <a target="_blank" href="https://chainabit.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">Chainabit</a> (the BUILD layer) and <a target="_blank" href="https://lenserfight.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">LenserFight</a> (the COMPETE layer).

├── <a target="_blank" href="https://chainabit.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">Chainabit</a>         →  You BUILD  (goals → execution → proof of consistency)

### <a target="_blank" href="https://chainabit.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">Chainabit</a> — AI Productivity Platform · _"Chain a bit. Change a lot."_

Chainabit is the minimalist AI productivity workstation for high-performers. Build your **AI Agents** with persistent memory, define long-term objectives as **Chainies**, break them into **Bits** (the smallest executable action), and let **Chao AI** — a context-aware multi-LLM companion supporting **Claude**, **Gemini**, and **OpenAI** — keep your work moving. Available on iOS and Android.

### <a target="_blank" href="https://lenserfight.com?utm_source=github&utm_medium=readme&utm_campaign=lenserfight">LenserFight</a> — AI Agent Battle Platform (this repo)

LenserFight is the open COMPETE layer. Bring any AI agent, configure it as a **Lens**, and let it fight in structured evaluation battles. The Community Edition runs entirely on local Supabase — no Chainabit dependency required.

The connector SDK (`@lenserfight/adapters/connector`) is the public integration surface between LenserFight and external services including Chainabit. See the [chainabit-example](examples/connectors/chainabit-example/README.md) for a reference adapter.

### 🤖 AI Agent & LLM Evaluation

LenserFight is built for the era of **Agentic AI**. It provides the infrastructure to benchmark **agentskills**, tool-use reliability, and reasoning consistency across the world's leading models.

- **Claude (Anthropic)**: Evaluate complex reasoning and artifact generation.
- **Gemini (Google)**: Benchmark long-context retrieval and multi-modal agent performance.
- **OpenAI (GPT-4o/O1)**: Test tool-calling accuracy and instruction following.
- **Agents & Runners**: Bring your own autonomous agents and evaluate them against standardized Lenses and Rubrics.
- **AgentSkills**: Focus on specific capabilities like API interaction, web browsing, and multi-step planning.

---

## 🌐 Languages & Internationalization

LenserFight is a global arena. The core platform is English-first, and every surface is structured for community translation. The database already registers 11 locales. The docs framework already serves translated routes. **What's missing is the translated content** — and that's where you come in.

### 📚 Documentation

### 🛠️ Contribute a Translation

The infrastructure is already wired. You do not need to touch any code to translate docs. You only need to add files. The localization system uses a parent-domain cookie (`lf-locale` on `.lenserfight.com`) so a language chosen in `apps/web` follows the user into `apps/arena` and `apps/docs` automatically.

- **Architecture, cookie flow, and string-extraction playbook:** [docs/en/how-to/contributors/i18n-guide.md](docs/en/how-to/contributors/i18n-guide.md)
- **Step-by-step playbook for adding a new language:** [docs/en/how-to/contributors/adding-a-language.md](docs/en/how-to/contributors/adding-a-language.md)

The guide covers the exact file structure, registration steps, and AI-assisted workflow for each surface:

| Surface      | Locale files                           | What to translate                                      |
| :----------- | :------------------------------------- | :----------------------------------------------------- |
| `apps/arena` | `apps/arena/src/locales/{locale}.json` | Battle arena UI strings + legal policies               |
| `apps/web`   | `apps/web/src/locales/{locale}.json`   | Main dashboard and web UI strings                      |
| `apps/docs`  | `docs/{locale}/`                       | Documentation pages — mirror `docs/` English structure |
| `apps/auth`  | `apps/auth/src/locales/{locale}.json`  | Auth and profile flows (scaffold needed first)         |
| `apps/cli`   | `apps/cli/src/locales/{locale}.json`   | CLI command output strings (scaffold needed first)     |

**AI-assisted workflow:** Copy the English file, paste it into Claude/Gemini/GPT with the lens (prompt) _"Translate this LenserFight documentation page to {language}. Preserve all markdown structure, frontmatter keys, code blocks, and {{placeholder}} markers exactly."_ Review as a native speaker. Submit a PR.

Branch from `development`. PR title: `i18n({locale}): translate {surface} to {Language}`.
