Reflection（反观）实现计划

面向 AI 代理的工作者： 使用 subagent-driven-development（推荐）或 executing-plans 逐任务实现此计划。步骤使用复选框（- [ ]）语法跟踪进度。

目标： 构建 Reflection 桌面应用——一个本地运行的复盘 agent，黎明初光视觉风格，三轮对话引擎，SQLite 存储，PyInstaller 打包为 .exe。

架构： Python FastAPI 本地服务器 + 纯 HTML/CSS/JS 前端 + SQLAlchemy/SQLite + httpx 直调 LLM API。前端通过 fetch 与后端通信。应用启动时自动打开浏览器。

技术栈： Python 3.11+, FastAPI, SQLAlchemy, SQLite, httpx, PyInstaller, 纯 HTML/CSS/JS（无框架）

你的角色不是导师、不是顾问、不是心理医生。你是一面镜子。

核心原则：
- 不评判、不建议、不分析、不贴标签
- 你的每个回应不超过三句话
- 保持安静、温暖、克制的语调
- 像深夜独自坐在高处看城市天际线——安静、开阔、俯瞰

第一轮（倾倒）：
- 用户倾诉，你只是接住。不追问、不引导。
- 等用户停下来，用一句话回响你听到的核心："我听到，你觉得……对吗？"

第二轮（觉察）：
- 从三个维度轻轻问一个问题，每次只问一个：
  念头层——"那时候，你心里冒出的第一句话是什么？"
  状态层——"身体有什么感觉？能量是往上的还是往下的？"
  道的层——"如果这件事是一个隐喻，它想告诉你什么？"
- 用户回答后再问另一个维度，直到三个维度都覆盖。
- 不要三个维度一起问。

第三轮（沉淀）：
- 提炼 3-5 条洞察，每条标注维度（念头 / 内在状态 / 道的体悟）。
  格式：
  [维度] 洞察内容
- 最后问："今天最值得带走的一句话是什么？"

始终用中文回应。"""

步骤 2：验证启动

cd "D:\MyAIWorkspace\project1：复盘agent"
Start-Process -NoNewWindow python -ArgumentList "-m", "reflection.main"

预期：终端输出 Reflection 启动信息，浏览器自动打开。

手动 Ctrl+C 停止。

任务 11：PyInstaller 打包

文件：

创建：project1：复盘agent/reflection/reflection.spec
步骤 1：编写 reflection.spec

# -*- mode: python ; coding: utf-8 -*-

import sys
from pathlib import Path

block_cipher = None

# 静态文件目录
static_dir = Path('reflection/static')

added_files = [
    (str(static_dir), 'reflection/static'),
]

a = Analysis(
    ['reflection/main.py'],
    pathex=[],
    binaries=[],
    datas=added_files,
    hiddenimports=['sqlalchemy', 'httpx', 'fastapi', 'uvicorn'],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)

pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries,
    a.zipfiles,
    a.datas,
    [],
    name='Reflection',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=False,
    disable_windowed_traceback=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
    icon=None,
)

步骤 2：执行打包

cd "D:\MyAIWorkspace\project1：复盘agent"
pyinstaller --clean reflection/reflection.spec

预期：生成 dist/Reflection.exe。

步骤 3：验证 .exe 可运行

Start-Process "D:\MyAIWorkspace\project1：复盘agent\dist\Reflection.exe"

预期：浏览器自动打开，显示 Reflection 首页。

任务 12：集成测试

文件：

创建：project1：复盘agent/reflection/tests/
创建：project1：复盘agent/reflection/tests/__init__.py
创建：project1：复盘agent/reflection/tests/test_database.py
创建：project1：复盘agent/reflection/tests/test_engine.py
步骤 1：编写 test_database.py

"""数据库模块测试。"""
import tempfile
import os
from pathlib import Path
from reflection.database import get_engine, get_db, Base, SessionModel, InsightModel, PatternModel


def test_create_tables():
    """验证表创建成功。"""
    db = get_db()
    tables = db.get_bind().table_names()
    assert "sessions" in tables
    assert "insights" in tables
    assert "patterns" in tables
    db.close()

    """验证创建 session。"""
    db = get_db()
    s = SessionModel(tag="test")
    db.add(s)
    db.commit()
    assert s.id is not None
    assert s.status == "active"
    db.delete(s)
    db.commit()
    db.close()


def test_create_insight():
    """验证创建 insight 并关联 session。"""
    db = get_db()
    s = SessionModel(tag="test")
    db.add(s)
    db.commit()

    i = InsightModel(session_id=s.id, dimension="thought", content="测试洞察")
    db.add(i)
    db.commit()
    assert i.id is not None
    assert len(s.insights) == 1

    db.delete(s)
    db.commit()
    db.close()

步骤 2：运行数据库测试

cd "D:\MyAIWorkspace\project1：复盘agent"
python -m pytest reflection/tests/test_database.py -v

预期：3 passed

步骤 3：编写 test_engine.py

"""复盘引擎测试（不依赖 LLM API）。"""
import json
from reflection.engine import start_session, _dimension_key, _get_phase_prompt


def test_start_session():
    """验证 start_session 创建 session 并返回开场白。"""
    sid, opening = start_session(tag="测试")
    assert sid > 0
    assert "今天" in opening
    assert "什么在你心里" in opening


def test_dimension_key():
    """验证维度中文→英文映射。"""
    assert _dimension_key("念头") == "thought"
    assert _dimension_key("内在状态") == "state"
    assert _dimension_key("道的体悟") == "dao"
    assert _dimension_key("未知") == "thought"


def test_phase_prompt():
    """验证三轮提示词包含正确阶段标记。"""
    p1 = _get_phase_prompt(1)
    assert "倾倒" in p1

    p2 = _get_phase_prompt(3)
    assert "觉察" in p2

    p3 = _get_phase_prompt(6)
    assert "沉淀" in p3

步骤 4：运行引擎测试

cd "D:\MyAIWorkspace\project1：复盘agent"
python -m pytest reflection/tests/test_engine.py -v

预期：3 passed

步骤 5：运行全部测试

cd "D:\MyAIWorkspace\project1：复盘agent"
python -m pytest reflection/tests/ -v

预期：6 passed
