A Claude Code skill that turns a .agent/ directory into a living expert system.
Using Claude Code plugin in Antigravity IDE?
Antigravity has a native .agent/ directory structure for workflows, rules, and experts.
But Claude Code doesn't understand it — it only knows Skills.
You don't want to migrate. You like Antigravity's workflow system.
Antigravity Loader is the bridge.
Antigravity Loader teaches Claude Code how to read Antigravity's .agent/ structure:
- Load Experts (persona-driven agents defined in Markdown)
- Execute Workflows (step-by-step SOPs, acting as Game Master)
- Enforce Rules (constitutional constraints applied as system instructions)
- Query Knowledge (reference libraries, specs, and domain docs)
All from Markdown files in your .agent/ directory.
Primary: Antigravity IDE users who installed Claude Code plugin
Secondary: Anyone using Claude Code who wants .agent/ directory management
If you're a "dual-blade" user (Antigravity + Claude), this tool saves you from migration hell.
1. Install
cp -r antigravity-loader ~/.claude/skills/antigravity-loader2. Configure Paths
Edit ~/.claude/skills/antigravity-loader/config.md:
- Single project? Set
GLOBAL_CORE = NONE - Multiple projects sharing resources? Set
GLOBAL_CORE = /path/to/shared/.agent - Want a global constitution (rules that apply to all projects)? Set
GLOBAL_CONSTITUTION = /path/to/global-rules.md
3. Structure Your Project
your-project/
└── .agent/
├── skills/ ← Expert definitions
│ └── my-expert/
│ └── SKILL.md
├── workflows/ ← Step-by-step SOPs
│ └── my-workflow.md
├── rules/ ← Constitutional constraints
└── knowledge/ ← Reference docs
4. Use
You: "load my-expert"
→ Claude reads skills/my-expert/SKILL.md and adopts that persona.
You: "/my-workflow" or "run my-workflow"
→ Claude reads workflows/my-workflow.md and guides you through it as Game Master.
You: "what are the rules?"
→ Claude reads rules/ and applies them as session constraints.
Dual-Layer (Optional)
| Layer | Location | Purpose |
|---|---|---|
| Project | {project}/.agent/ |
Project-specific resources |
| Global | Your configured path | Shared defaults across projects |
When a resource exists in both layers, Project wins.
4 Protocols
| Protocol | Trigger | Action |
|---|---|---|
| Summon Expert | @name / "load X" |
Reads SKILL.md, adopts persona |
| Execute Workflow | /workflow / "run X" |
Acts as Game Master, guides steps |
| Rule Enforcement | "rules" / starting complex task | Injects rules as constraints |
| Knowledge Access | "specs" / "TRAP" | Loads knowledge docs into context |

├── SKILL.md ← Required. Identity + capabilities.

v1.0.0 (2026-02-06)
- Initial public release
- Protocol 3: Added Global Constitution support for cross-project rules
- Config: Added
GLOBAL_CONSTITUTIONoptional path - Dual-layer architecture (Project + Global)
- 4 core protocols: Expert, Workflow, Rules, Knowledge
在 Antigravity IDE 裡用 Claude Code plugin？
Antigravity 有原生的 .agent/ 目錄結構（workflows、rules、experts）。
但 Claude Code 不認識它 — 它只懂 Skills。
你不想搬家。你喜歡 Antigravity 的 workflow 系統。
Antigravity Loader 就是這座橋。
Antigravity Loader 教 Claude Code 如何讀取 Antigravity 的 .agent/ 結構：
- Experts（人格化的 Agent）
- Workflows（標準作業流程，Claude 當 Game Master）
- Rules（憲法級約束，套為系統指令）
- Knowledge（參考文件庫、規格、領域知識）
全部從你的 .agent/ 目錄讀取。
主要用戶：Antigravity IDE 用戶，但裝了 Claude Code plugin
次要用戶：任何想要 .agent/ 目錄管理能力的 Claude Code 用戶
如果你是「二刀流」用戶（Antigravity + Claude），這工具讓你不用搬家。
1. 安裝
cp -r antigravity-loader ~/.claude/skills/antigravity-loader2. 配置路徑
編輯 ~/.claude/skills/antigravity-loader/config.md：
- 只有一個 project？設
GLOBAL_CORE = NONE - 多個 project 想共用資源？設
GLOBAL_CORE = /path/to/shared/.agent - 想要全域憲法（套用到所有 project 的規則）？設
GLOBAL_CONSTITUTION = /path/to/global-rules.md
3. 建立你的 .agent/
your-project/
└── .agent/
├── skills/ ← 專家定義
│ └── my-expert/
│ └── SKILL.md
├── workflows/ ← 標準作業流程
│ └── my-workflow.md
├── rules/ ← 憲法級約束
└── knowledge/ ← 參考文件
4. 開始用
你: "load my-expert"
→ Claude 讀 skills/my-expert/SKILL.md，進入該角色。
你: "/my-workflow" 或 "run my-workflow"
→ Claude 讀 workflows/my-workflow.md，當 Game Master 帶你走流程。
你: "what are the rules?"
→ Claude 讀 rules/ 裡的文件，套為本次 session 的約束。
雙層架構（可選）
| 層 | 位置 | 用途 |
|---|---|---|
| Project | {project}/.agent/ |
當前 project 專用 |
| Global | 你設定的共享路徑 | 跨 project 共用的預設 |
同名 resource 兩層都有時，Project 版本生效。
4 個 Protocol
| Protocol | 觸發 | 做什麼 |
|---|---|---|
| Summon Expert | @name / "load X" |
讀 SKILL.md，進入角色 |
| Execute Workflow | /workflow / "run X" |
當 Game Master，帶你走步驟 |
| Rule Enforcement | "rules" / 開始複雜任務 | 把 rules/ 裡的內容當為約束 |
| Knowledge Access | "specs" / "TRAP" | 讀 knowledge/ 並持續在 context 裡 |
skills/my-expert/

└── sovereign/ ← 可選。私密記憶（日記等）。

v1.0.0 (2026-02-06)
- 首次公開發布
- Protocol 3: 新增 Global Constitution 支援（跨專案規則）
- Config: 新增
GLOBAL_CONSTITUTION可選路徑 - 雙層架構（Project + Global）
- 4 個核心協議：Expert、Workflow、Rules、Knowledge
- Lightweight models (Haiku, Flash) may struggle with meta-instructions like "act as Game Master". Use thinking-class models (Sonnet+, Gemini Pro+).
- When workflows involve multiple experts, list the "Council" in the workflow file. The Loader will summon them first.
WORKFLOW_INDEX.mdis optional but highly recommended when you have 10+ workflows.
中文建議：
- 輕量模型（Haiku、Flash）可能在「當 Game Master」這種 meta-instruction 上執行不穩定。建議用 thinking-class 模型（Sonnet 以上，或 Gemini Pro 以上）。
- Workflow 裡如果要多個 Expert 互動，記得在文件裡列明 Council 成員。Loader 會替你先 summon。
WORKFLOW_INDEX.md不必，但強烈推薦。當 workflow 數量超過 10+，有一張索引會省你不少腦力。
