quark-coder ⬡

One command. Six backends. Three LLM providers. Built-in DASA multi-agent orchestration.

npm install -g quark-coder
quark use        # configure backend + LLM provider
quark start      # open AI coding session
quark super "build a REST API with auth"   # full DASA multi-agent pipeline

What it does

quark unifies every frontier AI coding tool behind one interface. Pick a backend — Bonsai, Claude Code, Gemini CLI, OpenCode, or Z.ai GLM Code. If it's not installed or fails, Quark auto-falls back through the chain, ending at the built-in Quark Agent which always works.

For complex tasks, quark super runs the full DASA pipeline: a Generator analyses the task, composes a specialised agent team, executes each agent with scoped context and tools, then validates output quality through a two-phase Watchdog before writing learnings back to a persistent Agent Pool.

Install

npm install -g quark-coder

Node.js 18+ required.

Quick start

quark use                                        # configure everything
quark agent "add rate limiting to the API"       # single-agent task
quark super "build JWT auth with refresh tokens" # full multi-agent pipeline
quark start                                      # open external CLI session

Backends

Install what you use — Quark falls back automatically.

| Key | Tool | Install | |-----|------|---------| | bonsai | Bonsai AI | npm i -g @bonsai-ai/cli | | claude | Claude Code | npm i -g @anthropic-ai/claude-code | | gemini | Gemini CLI | npm i -g @google/gemini-cli | | opencode | OpenCode | npm i -g opencode-ai | | glm | Z.ai GLM Code | npm i -g glm-code | | quark-agent | Built-in (always available) | — |

Fallback chain: bonsai → claude → gemini → opencode → glm → quark-agent

LLM Providers

For quark agent and quark super:

| Provider | Models | Env var | |----------|--------|---------| | anthropic | Claude Opus 4, Sonnet 4, Haiku | ANTHROPIC_API_KEY | | openrouter | 200+ — Gemini, Grok, DeepSeek, Llama, Mistral, Qwen | OPENROUTER_API_KEY | | glm | codegeex-4, glm-4-plus, glm-4-long, glm-4-flash | GLM_API_KEY |

Custom models

quark agent -m custom                         # interactive model picker
quark agent -m deepseek/deepseek-r1           # any model string directly
quark agent -m glm-4-plus:ft-your-finetune    # GLM fine-tunes work too
quark super --pick-model                       # pick model before DASA run

GLM format note

All providers share an Anthropic-format internal message history. For glm-4-* models this converts to native OpenAI-compat tool calling. For codegeex-4 and custom fine-tunes, tools are encoded as XML in the system prompt and parsed from responses — fully transparent to the agent loop.

Commands

quark use

Configure everything: backend, fallback, LLM provider, API key, model.

quark agent [task]

Single-agent with full tool access (bash, file create/write/edit, grep, glob, ask).

quark agent "fix the auth bug"
quark agent -p openrouter -m deepseek/deepseek-r1 "refactor this module"
quark agent -p glm -m codegeex-4 "add TypeScript types"
quark agent --list-models          # pick model interactively

quark super [task]

Super Quark Agent — full DASA pipeline.

quark super "build a FastAPI + MongoDB REST API"
quark super --pool-status          # view Agent Pool + Watchdog scores
quark super --pool-add             # add a custom agent to the pool
quark super --pick-model           # pick model before running

DASA pipeline steps:

Generator      → decomposes task, queries Agent Pool, emits Spawn Manifest
Executor       → runs each agent (scoped context, full tool access, 20 turns max)
Watchdog P1    → validates each agent: length, no stubs, required signals
Watchdog P2    → validates compound coherence across all agent outputs
Pool write-back→ updates agent scores, saves session learnings to ~/.quark/pool/

10 built-in agents auto-seeded to ~/.quark/pool/ on first run: Planner, Coder, Backend Specialist, Frontend Specialist, Tester, Reviewer, Debugger, Schema Designer, Security Auditor, Docs Writer. Add your own with quark super --pool-add.

quark start

Open interactive session with the active backend.

quark run [task]

One-shot task via active backend.

quark status

Show backend availability, provider, API key status, pool location.

quark login / quark logout

Auth for backends that need it (Bonsai).

Configuration

Stored at ~/.config/quark-coder/config.json. All keys also readable from env vars (env takes priority).

Examples

# Single agent
quark agent "add pagination to the users endpoint"
quark agent -p glm -m glm-4-plus "fix the TypeScript errors"
quark agent -p openrouter -m google/gemini-2.5-pro "write integration tests"

# DASA multi-agent
quark super "user auth: register, login, JWT refresh, logout"
quark super -p openrouter -m anthropic/claude-opus-4 "add dark mode"
quark super -p glm -m glm-4-plus "optimise all database queries"

# External CLI
quark start --dir ./backend
quark run "fix the CORS error" --dir ./api
