🐳 CCG on DeepSeek Harness — dsh-ccg

The same role matrix, running natively inside DeepSeek Harness. It ships inside this package — no second install, no second version to track.

npx ccg-workflow dsh install    # every profile found; --profile <name> for one
npx ccg-workflow dsh list       # which profiles have it

Or pick D. DeepSeek Harness from npx ccg-workflow.

Seven role-pinned delegation tools, each on its own model with its own expert persona — and two things the Claude Code side cannot do as cleanly:

• Model panels. Give one role several models and they all answer the same brief independently, rendered side by side in the conversation. Nothing votes, nothing is averaged — disagreement is the finding.
• Live teammates. ccg_team hires a role as a colleague that stays alive across turns, owns its own files (a colliding hire is refused, not warned about), and reports back on its own. Every hire asks you to approve it first.

No external CLI, no binary bridge, no cold-start tax — every hop is a provider API request. Source lives in dsh-ccg/; full README →

🧩 Also by the author

DSH Marketplace — a directory of DeepSeek Harness plugins. 2,500+ indexed across 14 categories, bilingual EN / 中文.

Not a sponsor — same author as CCG, built out of a plain annoyance: DSH plugins are multiplying fast, but figuring out what one does, whether it still installs, and what the command actually is meant opening one GitHub README after another. So the install commands here are put through a throwaway container first. A plugin only gets a check mark if it really installs — and if it can't, the listing says why (buried in a monorepo subdirectory, never published to npm, and so on). A verified index, not another awesome list.

dsh plugin --profile web add dshmarketplace-plugin   # browse the store from inside DSH
npx dshmarketplace-cli add owner/repo                # install any plugin from your shell

There is also a Python SDK and a public API. Early days — bug reports and plugin submissions are very welcome on GitHub.

What is CCG?

CCG is a workflow engine for Claude Code. It turns Claude into a multi-model orchestrator — Claude stays in control while dispatching specialized work to Codex (OpenAI), Grok (xAI), Kimi Code (Moonshot), and Antigravity through a Go binary bridge.

One command. Describe what you want. The engine handles the rest.

Architecture

<div align="center"> <img src="assets/readme/architecture.png" alt="CCG Architecture" width="800"> </div>

Claude Code is the lead orchestrator. It analyzes your intent, selects a strategy, and manages the entire workflow. The Hook Engine injects state every turn so Claude never loses context — even after compaction. The codeagent-wrapper (a compiled Go binary) bridges Claude to external models for parallel analysis and review.

How It Works

You: /ccg:go add JWT authentication to this API

CCG Engine:
  1. Reads project context (git status, tech stack, file structure)
  2. Classifies: feature / L complexity / backend / high risk
  3. Selects strategy: full-collaborate
  4. Creates .ccg/tasks/add-jwt-auth/task.json
  5. Launches dual-model analysis (Codex + Gemini in parallel)
  6. Produces plan → HARD STOP for your approval
  7. Spawns Agent Teams Builders for parallel implementation
  8. Runs quality gates + dual-model cross-review
  9. Reports results

Every turn, a hook injects:
  <ccg-state>
  Task: add-jwt-auth (in_progress)
  Strategy: full-collaborate
  Phase: 4-implementation
  </ccg-state>

10 Built-in Strategies

The engine auto-selects the right strategy based on task type and complexity:

| Strategy | When | External Models | Agent Teams | |----------|------|:---:|:---:| | direct-fix | Simple bug, single file | — | — | | quick-implement | Small feature, clear scope | — | — | | guided-develop | Medium feature, needs planning | Single | — | | full-collaborate | Complex feature, multi-module | Dual parallel | ✓ | | debug-investigate | Complex bug, unknown cause | Dual diagnosis | — | | refactor-safely | Code restructuring | Dual review | — | | deep-research | Technical research | Dual exploration | — | | optimize-measure | Performance optimization | Optional | — | | review-audit | Code review | Dual cross-review | — | | git-action | commit, rollback, branches | — | — |

Simple tasks run fast with zero overhead. Complex tasks get the full engine.

Core Features

Hook Engine — Never Lose Context

4 JavaScript hooks inject state into every Claude Code session:

| Hook | Event | What it does | |------|-------|-------------| | workflow-state.js | Every turn | Injects current task state as breadcrumb | | session-start.js | Session start/compact | Re-injects full project context | | subagent-context.js | Agent/Bash spawn | Injects spec directly into subagent prompts | | skill-router.js | Every turn | Auto-injects domain knowledge by keyword |

Context survives compaction. Sub-agents born with spec in their prompt. Zero state loss.

Task System — Persistent Lifecycle

Medium+ complexity tasks get a persistent directory:

.ccg/tasks/add-jwt-auth/
├── task.json         # Status, strategy, phase, gate
├── requirements.md   # Enhanced requirements
├── plan.md           # Approved implementation plan
├── context.jsonl     # Spec files for sub-agent injection
├── review.md         # Review results
└── research/         # Persisted research findings

Quality Gates — Built-in Security & Quality

| Gate | Trigger | |------|---------| | /ccg:verify-security | New modules, security changes | | /ccg:verify-quality | Changes > 30 lines | | /ccg:verify-change | Doc sync check | | /ccg:verify-module | Module structure check | | /ccg:gen-docs | Auto-generate README + DESIGN |

100+ Domain Knowledge Files

When your message mentions security, caching, RAG, Kubernetes, etc., the relevant knowledge file is auto-injected. 10 domains, 61 files:

Security · Architecture · DevOps · AI/MLOps · Development · Frontend Design · Infrastructure · Mobile · Data Engineering · Orchestration

Standalone Skills — battle-tested website workflows (v3.5.1)

Self-contained skills, each usable on its own or auto-triggered by intent. Drawn from real site-building work and shipped with their scripts:

| Skill | What it does | |-------|-------------| | /ccg:bt-panel | Drive a BaoTa / aaPanel server over its HTTP API — deploy a build, update a live site, read/write files, run shell, run MySQL. No SSH or rsync; just a panel URL + API key. Ships bt_client.py + one-shot bt_deploy.py. | | /ccg:seo-page-builder | Build, audit, or optimize SEO tool pages (AI generator / remover / enhancer / converter / editor). SERP-intent driven, with a runnable onpage-audit.py keyword-density meter. | | /ccg:adsense-site-auditor | Audit a site for Google AdSense readiness against the full official checklist — eligibility, ownership, content quality, ads.txt, privacy, Publisher Policies — before you apply or after a rejection. |

bt-panel reads credentials only from env vars / a git-ignored sites.json; nothing is hardcoded. seo-page-builder is adapted from yuzeiki's skill of the same name (see its SKILL.md).
