[![Serac Terminal UI](packages/web/src/assets/lander/screenshot.png)](https://serac.build)

Serac is a terminal-native AI development agent purpose-built for **ServiceNow**. It brings 429 ServiceNow MCP tools, 55 bundled domain skills (including Blast Radius impact analysis), and 20+ AI providers into your own terminal — your editor, your keys (BYOK), and any instance you connect to. It's built for ServiceNow developers and the consultants who work across many client instances. Serac extends the open-source [opencode](https://github.com/anomalyco/opencode) agent with a deep ServiceNow domain layer.

#### Installation Directory

The install script respects the following priority order for the installation path:

1. `$SERAC_INSTALL_DIR` - Custom installation directory
2. `$XDG_BIN_DIR` - XDG Base Directory Specification compliant path
3. `$HOME/.serac/bin` - Default

```bash
# Examples
SERAC_INSTALL_DIR=/usr/local/bin curl -fsSL https://serac.build/install | bash
XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://serac.build/install | bash
```

### Agents

Serac includes two built-in agents you can switch between with the `Tab` key.

- **build** - Default, full-access agent for development work
- **plan** - Read-only agent for analysis and code exploration
  - Denies file edits by default
  - Asks permission before running bash commands
  - Ideal for exploring unfamiliar codebases or planning changes

Also included is a **general** subagent for complex searches and multistep tasks.
This is used internally and can be invoked using `@general` in messages.
