Multi-access agentic coding tool — TUI, CLI, and REST API with JSON output

🥷 codrninja

Multi-Access Agentic Coding Tool — use it from a terminal TUI, shell scripts, or as a backend for AI agents. Every command outputs structured JSON, so humans and machines use the exact same interface.

How you can access it

Access	Use case
codrninja	Interactive TypeScript TUI for humans
codrninja send <session> "<msg>"	Scripting, CI pipelines
codrninja build <session> "<task>"	Agent-driven coding tasks
REST API on localhost:7384	External agents (openclaw, n8n, custom)

An external agent can list your sessions, send messages into them, trigger builds, run tests, and read results — all in JSON — without touching the TUI at all.

Providers

Provider	Setup	Notes
claude-cli	Claude Code installed	Uses your Claude Code subscription — no API key needed
OpenAI	OAuth or API key	gpt-4o, gpt-5, codex models
Anthropic	OAuth or API key	claude-sonnet, claude-opus
Ollama	Local server	Any local model
OpenRouter	API key	Access to all major models

Install

pip3 install codrninja

Start the TUI:

codrninja

The server starts automatically on port 7384. Configure your provider on first launch with /provider.

TypeScript TUI

codrninja looks for the TUI at ~/codrninja-tui. Clone it once:

git clone https://github.com/20ZollCoder/codrninja-tui ~/codrninja-tui
cd ~/codrninja-tui && npm install

Agent / CLI access

All commands output JSON with a $schema field — ready to pipe into jq or any agent.

# List sessions
codrninja list-sessions

# Send a message to a session
codrninja send my-project "what does this file do?"

# Run the coding agent on a task (build mode — writes files, runs commands)
codrninja build my-project "add input validation to the login form"

# Run in plan mode (reasons and plans, doesn't execute)
codrninja plan my-project "how should we restructure the auth module?"

# Show session history
codrninja show-session my-project

# Run tests
codrninja test "pytest -q"

# Execute a shell command
codrninja exec "npm run build"

# Web search
codrninja search "fastapi streaming response"

# Git commit
codrninja commit "feat: add login validation"

Example: an openclaw agent picks up a session you already have open in the TUI:

# You're working in the TUI on session "backend-api"
# An openclaw agent can continue in the same session:
codrninja build backend-api "add rate limiting to the /auth endpoint"

# Or create its own session
codrninja create-session agent-task-1
codrninja build agent-task-1 "write unit tests for auth.py"

TUI slash commands

Command	Description
/provider	Switch or configure AI provider
/model	Change model for this session
/build <task>	Run build agent
/plan <task>	Run plan agent
/exec <cmd>	Run a shell command
/diff	Show current git diff
/commit <msg>	Git add -A and commit
/test	Run tests
/search <query>	Web search
/fetch <url>	Fetch a web page
/clear	Clear the conversation
/undo	Remove the last message pair
/session	Show session info
/status	Show provider / model status
/help	Show all commands
/exit	Quit

Sessions

Sessions store conversation history, model/provider settings, and file change tracking. They're shared across all access methods — what you do in the TUI is visible via CLI and vice versa.

# Open a specific session directly
codrninja my-project

# Or via env var (useful for agents)
CODRNINJA_SESSION=my-project codrninja

REST API

The server exposes a full REST API that external agents can use directly:

GET  /sessions           → list all sessions
POST /sessions           → create session
GET  /sessions/{name}    → get session history
POST /sessions/{name}/stream → stream agent execution (SSE)
GET  /providers          → list providers and auth status
POST /config/provider    → set active provider
POST /config/model       → set model
GET  /models             → list available models
GET  /version            → server version

Configuration

Settings live in ~/.config/codrninja/config.json and can be changed from the TUI via /provider and /model.

Override the server address:

codrninja serve --port 8000
CODRNINJA_SERVER=http://127.0.0.1:8000 codrninja
