架構概覽
SAGE(Self-improving Autonomous Generation Engine)是一個基於 LangGraph 的協調器架構,透過專業代理(規劃者、編碼者、審查者、測試工程師)和模型路由器,將自然語言提示詞轉化為生產級的程式碼、測試和驗證。
核心組件與流程
1. 交互式 Shell 與指令系統
SAGE 的預設 UX 是持久 REPL,使用 Python Prompt Toolkit 提供可靠的終端體驗:
# 啟動交互式 shell
sage # 開啟 slash-command shell
# 常用指令
/run "Add JWT auth to the API" # 執行完整流程
/research # 交互式計劃審查
/auto # 減少交互檢查點
/silent # 自主模式,跳過失敗任務
/plan-only # 僅輸出計劃,不執行工具
/dry-run # 不應用檔案補丁
環境變數控制:
SAGE_SHELL_SIMPLE_INPUT=1- 禁用 prompt_toolkit,使用 plain input()SAGE_SHELL_NO_STATUSBAR=1- 隱藏底部狀態欄SAGE_RUN_OUTPUT=full- 詳細的驗證標籤和指標行SAGE_VERIFY_TIMEOUT_S=30- 計劃驗證子進程超時限制(秒)
2. 模型路由與配置
模型路由基於 models.yaml 配置檔案:
# ~/.config/sage/models.yaml
primary: gpt-4o
fallback: gpt-4o-mini
test_profile:
primary: gpt-4o-mini
fallback: gpt-4o-mini
角色配置:
- 每個代理角色都有 primary 和 fallback 模型
- 支援本地模型透過 Ollama:
ollama pull qwen2.5-coder:1.5b ollama pull nomic-embed-text
環境變數:
SAGE_MODEL_PROFILE=test- 強制使用測試配置(小型本地模型)SAGE_MODELS_YAML=~/.config/sage/models.yaml- 自訂配置路徑
3. 代理管道
完整流程:
- 規劃者 - 解析目標,生成 DAG
- 編碼者 - 實作代碼
- 審查者 - 檢查程式碼品質
- 測試工程師 - 執行測試
- 驗證 - 驗證輸出
交互式審查(預設模式):

# 遇到計劃時顯示:
# [a]pprove [r]eject [e]dit .sage/last_plan.json
自動化執行:
sage run "Add JWT auth to the API" --auto # 減少交互
sage run "Add JWT auth to the API" --silent # 自主模式

關鍵設計決策與權衡
交互式 vs 自主執行
交互式模式(–research):
- 優點:人工審查計劃,減少錯誤
- 缺點:增加等待時間,降低生產效率
- 適用場景:初次實作、複雜任務
自主模式(–silent):

- 缺點:跳過失敗任務,可能隱藏問題
- 適用場景:日常開發、重複任務
選擇策略:
- 初次實作:使用
--research,逐步審查 - CI/CD:使用
--auto,減少等待 - 高風險任務:使用
--research+ 手動審查
模型路由策略
本地模型優化(Ollama):

Architecture Overview
SAGE (Self-improving Autonomous Generation Engine) is a coordinator architecture based on LangGraph that uses professional agents (planners, coders, reviewers, test engineers) and model routers to convert natural language prompts into production-level code, testing and verification.
Core components and processes
1. Interactive Shell and command system
SAGE’s default UX is a persistent REPL that uses the Python Prompt Toolkit to provide a reliable terminal experience:
# 啟動交互式 shell
sage # 開啟 slash-command shell
# 常用指令
/run "Add JWT auth to the API" # 執行完整流程
/research # 交互式計劃審查
/auto # 減少交互檢查點
/silent # 自主模式,跳過失敗任務
/plan-only # 僅輸出計劃,不執行工具
/dry-run # 不應用檔案補丁
Environment variable control:
SAGE_SHELL_SIMPLE_INPUT=1- disable prompt_toolkit, use plain input()SAGE_SHELL_NO_STATUSBAR=1- hide the bottom status barSAGE_RUN_OUTPUT=full- Detailed validation tags and metric rowsSAGE_VERIFY_TIMEOUT_S=30- Plan validation subprocess timeout limit (seconds)
2. Model routing and configuration
Model routing is based on the models.yaml configuration file:
# ~/.config/sage/models.yaml
primary: gpt-4o
fallback: gpt-4o-mini
test_profile:
primary: gpt-4o-mini
fallback: gpt-4o-mini
Character Configuration:
- Each agent role has primary and fallback models
- Support local models through Ollama:
ollama pull qwen2.5-coder:1.5b ollama pull nomic-embed-text
Environment variables:
SAGE_MODEL_PROFILE=test- Force use of test configuration (small local model)SAGE_MODELS_YAML=~/.config/sage/models.yaml- Custom configuration path
3. Agent pipeline
Complete process:
- Planner - parse the target and generate DAG
- Coder - implements the code
- Reviewer - Check code quality
- Test Engineer - Perform testing
- Validation - Validation output
Interactive Review (Preset Mode):
sage run "Add JWT auth to the API" --research
# 遇到計劃時顯示:
# [a]pprove [r]eject [e]dit .sage/last_plan.json
Automated execution:
sage run "Add JWT auth to the API" --auto # 減少交互
sage run "Add JWT auth to the API" --silent # 自主模式

Key Design Decisions and Tradeoffs
Interactive vs autonomous execution
Interactive mode (–research):
- Advantages: Manual review of plans, reducing errors
- Disadvantages: increased waiting time, reduced production efficiency
- Applicable scenarios: first implementation, complex tasks
Autonomous mode (–silent):
- Advantages: fast execution, suitable for CI/CD
- Disadvantages: skip failed tasks, may hide problems
- Applicable scenarios: daily development, repetitive tasks
Select Strategy:
- First implementation: using
--research, step by step review - CI/CD: use
--auto, reduce waiting - High risk tasks: use
--research+ manual review
Model routing strategy
Local model optimization (Ollama):
# 編碼模型
ollama pull qwen2.5-coder:1.5b
# 嵌入模型
ollama pull nomic-embed-text
Hybrid Deployment:
- Complex tasks: use GPT-4o (cloud)
- Repeat tasks: use local model (offline)
- Test validation: using small models (fast)
Memory level
SAGE provides multiple layers of memory:
- Project Memory -
.sage/memory/(project specific) - Conversation Memory -
.sage/chat_sessions/(Interactive Chat) - System Memory -
.sage/system_state.json(system status) - Periodic Summary -
memory/weekly_digest.md
