+# 向 sipeed/picoclaw 提交 PR 指南
+
+## 当前状态
+
+✅ **已完成**：
+- 安全修复已提交到分支 `security-and-prs-merge`（修复 #1525、#1527、#1529）
+- 前 5 个 PR 已拉取到本地（pr-110, pr-154, pr-159, pr-181, pr-182）
+
+⚠️ **PR 合并冲突**：前 5 个 PR 与 main 存在较大冲突（尤其是 #110 对 http_provider 的重构），自动合并会破坏代码。建议单独提交安全修复 PR。

+```markdown
+## Summary
+Addresses security issues reported in the picoclaw repository.
+
+## Changes
+
+### #1525 - exec.allow_remote default to false
+- Changed default from `true` to `false` to restrict exec tool to local context
+- Reduces risk of remote shell execution from non-local sessions
+
+### #1527 - Tighten JSONL session store permissions
+- Sessions directory: 0755 → 0700 (owner only)
+- JSONL and meta files: 0644 → 0600 (owner read/write only)
+
+### #1529 - Refuse public web mode without allowed_cidrs
+- Prevents binding to 0.0.0.0 without explicit CIDR restrictions
+- Fails at startup with clear error message when public=true and allowed_cidrs is empty
+
+## Files Modified
+- pkg/config/defaults.go
+- pkg/config/config_test.go
+- pkg/memory/jsonl.go
+- web/backend/main.go

+## 关于前 5 个 PR 的合并
+
+前 5 个 PR（按创建时间排序）：
+| # | 标题 | 作者 | 状态 |
+|---|------|------|------|
+| 110 | feat(provider): add gemini google-generative-ai compatibility | fuhao009 | 与 main 有冲突 |
+| 154 | feat: add minimax provider support | Danieldd28 | 待合并 |
+| 159 | fix: preserve reasoning_content for thinking models | siciyuan404 | 待合并 |
+| 181 | Enable Discord message intents | Paraguanads | 待合并 |
+| 182 | feat: add slash command support | Tuzfucius | 待合并 |
+
+PR #110 与当前 main 的 `pkg/providers/http_provider.go` 和 `pkg/config/config.go` 存在结构性冲突，需要人工审查后合并。
+
+如需合并其他 PR，可手动执行：
+```powershell
+git merge pr-154  # 逐个尝试
+# 解决冲突后
+git add -A
+git commit -m "Merge PR 154"
+```
+
+---
+
+## 若 git commit 报错 "unknown option trailer"
+
+你的 Git 可能配置了 commit 模板或别名。使用完整路径绕过：
+```powershell
+& "C:\Program Files\Git\bin\git.exe" commit -m "your message"
+```
