**A lightweight agentic tooling core with API, CLI and REPL interfaces.**

REPL.io is deliberately small and auditable zero-dependency agentic core built on a single streaming agent loop. The model plans, the tool registry acts, and one loop serves three front-ends: an interactive REPL, a headless one-shot CLI, and an HTTP API.

## Why

- **Zero dependencies** — everything is Python standard library. No dependency tree to audit, no supply-chain surface, no lockfile churn
- **One agent loop** — a single SSE stream per turn powers the REPL, the CLI, and the API. No duplicated logic across front-ends
- **Local-first** — config and session logs live on your disk. Bring your own provider key, or run fully local

## Features

- **Agentic REPL** — streaming token-by-token output, dimmed thinking, markdown-aware rendering, readline history and tab completion
- **Tool calling** — web search, page fetching, file read/write/search, and shell execution via OpenAI-compatible function calling
- **Permissions** — every tool is gated by `allow` / `ask` / `deny`, with path-scoped confirmations for anything outside your worktree
- **Plugins** — external repositories register tools, providers, and slash commands; the core stays zero-dependency and plugin deps are imported lazily, only when you activate a plugin
- **Multi-provider** — Ollama, OpenAI, Groq, Anthropic, plus any OpenAI-compatible endpoint, with automatic detection from the base URL
- **Sessions** — complete append-only conversation logs, including every tool call and its result
- **Compaction** — summarize long conversations and trim the provider context without losing history
- **Headless modes** — `replio run` for scripting and `replio serve` for an HTTP JSON API

## Quick Start

```bash
pipx install replio
replio
```

Or from source:

```bash
git clone https://github.com/emyasnikov/replio.git && cd replio
python3 -m venv .venv && .venv/bin/pip install -e .
.venv/bin/replio
```

## Usage

### REPL

First-time setup with `/connect`, then type any message. Tab-complete `/` commands and session names. Use arrow keys to navigate history.

```
>>> /connect
  Provider [ollama]:
  Base URL [https://ollama.com]:
  API key: ...
  Model [gpt-oss:20b-cloud]:
>>> Hi
<<< Hello! How can I help you today?
>>> /exit
```

### CLI

Stream plain text with `--output text` or return the results as JSON, log tool status and diagnostics to stderr with `--verbose`, and address a persistent session with `--session-id <id>`. Tools that require confirmation are auto-denied in by default, just pass `--yes` to approve them.

```bash
replio run --prompt "Hi"
{
  "content": "Hello! How can I help you today?",
  "thinking": null,
  "tool_calls": [],
  "errors": [],
  "duration": 7.0,
  "usage": null,
  "model": "gpt-oss:20b-cloud",
  "provider": "ollama",
  "session": "20260814_192251_hi",
  "status": "ok"
}
```

### API

Server exposes different JSON endpoints like `POST /chat` (`{"prompt": ...}`, optionally `{"session_id": ...}`) returns the same turn result as the CLI etc.

```bash
replio serve &
curl localhost:8787/chat -X POST -d '{"prompt": "Hi"}'
{"content": "Hello! 👋 How can I help you today?", "thinking": null, "tool_calls": [], "errors": [], "duration": 7.0, "usage": null, "model": "gpt-oss:20b-cloud", "provider": "ollama", "session": "20260814_192711_hi", "status": "ok"}
```

## Roadmap

Personas and delegation are planned next. The directory-based plugin system is in place — see [docs/plugins.md](docs/plugins.md) for building and managing plugins. Open tasks live in [TODO.md](TODO.md).
