reldo 0.4.0

Claude-powered code review orchestrator that coordinates specialized review agents

Reldo

"The librarian has reviewed your code."

A Claude-powered code review orchestrator that coordinates specialized review agents.

Named after the Varrock Palace librarian in RuneScape who researches and checks things against ancient tomes.

Installation

# From PyPI
pip install reldo

# Or with uv
uv tool install reldo

Usage

As a Library

from reldo import Reldo, ReviewConfig
from pathlib import Path

# Load config from file
config = ReviewConfig.from_file(Path(".claude/reldo.json"))
reldo = Reldo(config=config)

# Run a review - single prompt argument
result = await reldo.review(
    prompt="Review app/Models/User.php for backend conventions. Context: Added user registration."
)

print(result.text)
print(f"Tokens used: {result.total_tokens}")

As a CLI

# Basic review
reldo review --prompt "Review app/Models/User.php"

# With JSON output (for CI)
reldo review --prompt "Review $(git diff --name-only HEAD)" --json --exit-code

# With custom config
reldo review --prompt "..." --config .claude/reldo.json

Configuration

Create .reldo/settings.json:

{
  "prompt": ".reldo/orchestrator.md",
  "allowed_tools": ["Read", "Glob", "Grep", "Bash", "Task"],
  "model": "claude-sonnet-4-20250514",
  "timeout_seconds": 300
}

Configuration Options

Option	Type	Default	Description
prompt	string	required	Path to orchestrator prompt file
allowed_tools	string[]	["Read", "Glob", "Grep", "Bash", "Task"]	Tools available to the orchestrator
mcp_servers	object	{}	MCP server configurations
setting_sources	string[]	["project"]	Where to discover agents from (see Agent Discovery)
agents	object	{}	Additional agent definitions (merged with discovered agents)
model	string	"claude-sonnet-4-20250514"	Claude model to use
timeout_seconds	int	180	Maximum review duration
cwd	string	current directory	Working directory
logging	object	{"enabled": true, ...}	Logging configuration

Agent Discovery

Reldo automatically discovers agents from your project's .claude/agents/ directory. This means you can use the same agents that Claude Code uses - no duplication needed.

How It Works

By default, setting_sources is set to ["project"], which tells the Claude Agent SDK to load agents from .claude/agents/. These agents are immediately available to your review orchestrator.

your-project/
├── .claude/
│   └── agents/
│       ├── backend-reviewer.md      # ← Auto-discovered
│       ├── frontend-reviewer.md     # ← Auto-discovered
│       └── architecture-reviewer.md # ← Auto-discovered
└── .reldo/
    └── settings.json                # ← No agent config needed!

Agent File Format

Agents in .claude/agents/ use markdown with YAML frontmatter:

---
name: backend-reviewer
description: Reviews PHP/Laravel code for conventions and patterns
model: inherit
---

# Backend Reviewer

You review PHP/Laravel code for best practices...

Controlling Agent Discovery

The setting_sources option controls where agents are loaded from:

Value	Behavior
["project"] (default)	Loads agents from .claude/agents/
["project", "local"]	Also includes local settings overrides
["user", "project", "local"]	Includes user-global agents too
[]	Disables auto-discovery (only explicit agents)

Merging Explicit Agents

If you define agents in .reldo/settings.json, they are merged with discovered agents:

{
  "prompt": ".reldo/orchestrator.md",
  "agents": {
    "reldo-specific-agent": {
      "description": "An agent only for reldo reviews",
      "prompt": ".reldo/agents/special.md"
    }
  }
}

Result: Both .claude/agents/* AND reldo-specific-agent are available.

Disabling Auto-Discovery

To use only explicitly defined agents:

{
  "prompt": ".reldo/orchestrator.md",
  "setting_sources": [],
  "agents": {
    "my-reviewer": {
      "description": "Custom reviewer",
      "prompt": ".reldo/agents/my-reviewer.md"
    }
  }
}

MCP Server Configuration

Reldo supports MCP (Model Context Protocol) servers for extended functionality:

{
  "mcp_servers": {
    "server-name": {
      "command": "executable",
      "args": ["arg1", "arg2"],
      "env": {
        "ENV_VAR": "value"
      }
    }
  }
}

Variable Substitution

MCP server configurations support variable substitution:

• ${cwd} - Replaced with the working directory

{
  "mcp_servers": {
    "serena": {
      "command": "uvx",
      "args": ["serena", "start-mcp-server", "--project", "${cwd}"]
    }
  }
}
