 # codeagent-wrapper
 
-`codeagent-wrapper` 是一个用 Go 编写的“多后端 AI 代码代理”命令行包装器：用统一的 CLI 入口封装不同的 AI 工具后端（Codex / Claude / Gemini / Opencode），并提供一致的参数、配置与会话恢复体验。
+[English](README.md) | [中文](README_CN.md)
 
-入口：`cmd/codeagent/main.go`（生成二进制名：`codeagent`）和 `cmd/codeagent-wrapper/main.go`（生成二进制名：`codeagent-wrapper`）。两者行为一致。
+A multi-backend AI code agent CLI wrapper written in Go. Provides a unified CLI entry point wrapping different AI tool backends (Codex / Claude / Gemini / OpenCode) with consistent flags, configuration, skill injection, and session resumption.
 
-## 功能特性
+Entry point: `cmd/codeagent-wrapper/main.go` (binary: `codeagent-wrapper`).
 
-- 多后端支持：`codex` / `claude` / `gemini` / `opencode`
-- 统一命令行：`codeagent [flags] <task>` / `codeagent resume <session_id> <task> [workdir]`
-- 自动 stdin：遇到换行/特殊字符/超长任务自动走 stdin，避免 shell quoting 地狱；也可显式使用 `-`
-- 配置合并：支持配置文件与 `CODEAGENT_*` 环境变量（viper）
-- Agent 预设：从 `~/.codeagent/models.json` 读取 backend/model/prompt 等预设
-- 并行执行：`--parallel` 从 stdin 读取多任务配置，支持依赖拓扑并发执行
-- 日志清理：`codeagent cleanup` 清理旧日志（日志写入系统临时目录）
+## Features
 
-## 安装
+- **Multi-backend support**: `codex` / `claude` / `gemini` / `opencode`
+- **Unified CLI**: `codeagent-wrapper [flags] <task>` / `codeagent-wrapper resume <session_id> <task> [workdir]`
+- **Auto stdin**: Automatically pipes via stdin when task contains newlines, special characters, or exceeds length; also supports explicit `-`
+- **Config merging**: Config files + `CODEAGENT_*` environment variables (viper)
+- **Agent presets**: Read backend/model/prompt/reasoning/yolo/allowed_tools from `~/.codeagent/models.json`
+- **Dynamic agents**: Place a `{name}.md` prompt file in `~/.codeagent/agents/` to use as an agent
+- **Skill auto-injection**: `--skills` for manual specification, or auto-detect from project tech stack (Go/Rust/Python/Node.js/Vue)
+- **Git worktree isolation**: `--worktree` executes tasks in an isolated git worktree with auto-generated task_id and branch
+- **Parallel execution**: `--parallel` reads multi-task config from stdin with dependency-aware topological concurrent execution and structured summary reports
+- **Backend config**: `backends` section in `models.json` supports per-backend `base_url` / `api_key` injection
+- **Claude tool control**: `allowed_tools` / `disallowed_tools` to restrict available tools for Claude backend
+- **Stderr noise filtering**: Automatically filters noisy stderr output from Gemini and Codex backends
+- **Log cleanup**: `codeagent-wrapper cleanup` cleans old logs (logs written to system temp directory)
+- **Cross-platform**: macOS / Linux / Windows
 
-要求：Go 1.21+。
+## Installation
 
-在仓库根目录执行：
+### Recommended (interactive installer)
 
 ```bash
-go install ./cmd/codeagent
-go install ./cmd/codeagent-wrapper
+npx github:cexll/myclaude
 ```
 
-安装后确认：
+Select the `codeagent-wrapper` module to install.
+
+### Manual build
+
+Requires: Go 1.21+.
 
 ```bash
-codeagent version
-codeagent-wrapper version
+# Build from source
+make build
+
+# Or install to $GOPATH/bin
+make install
 ```
 
-## 使用示例
-
-最简单用法（默认后端：`codex`）：
+Verify installation:
 
 ```bash
-codeagent "分析 internal/app/cli.go 的入口逻辑，给出改进建议"
+codeagent-wrapper --version
 ```
 
-指定后端：
+## Usage
+
+Basic usage (default backend: `codex`):
 
 ```bash
-codeagent --backend claude "解释 internal/executor/parallel_config.go 的并行配置格式"
+codeagent-wrapper "analyze the entry logic of internal/app/cli.go"
 ```
 
-指定工作目录（第 2 个位置参数）：
+Specify backend:
 
 ```bash
-codeagent "在当前 repo 下搜索潜在数据竞争" .
+codeagent-wrapper --backend claude "explain the parallel config format in internal/executor/parallel_config.go"
 ```
 
-显式从 stdin 读取 task（使用 `-`）：
+Specify working directory (2nd positional argument):
 
 ```bash
-cat task.txt | codeagent -
+codeagent-wrapper "search for potential data races in this repo" .
 ```
 
-恢复会话：
+Explicit stdin (using `-`):
 
 ```bash
-codeagent resume <session_id> "继续上次任务"
+cat task.txt | codeagent-wrapper -
 ```
 
-并行模式（从 stdin 读取任务配置；禁止位置参数）：
+HEREDOC (recommended for multi-line tasks):
 
 ```bash
-codeagent --parallel <<'EOF'
+codeagent-wrapper --backend claude - <<'EOF'
+Implement user authentication:
+- JWT tokens
+- bcrypt password hashing
+- Session management
+EOF
+```
+
+Resume session:
+
+```bash
+codeagent-wrapper resume <session_id> "continue the previous task"
+```
+
+Execute in isolated git worktree:
+
+```bash
+codeagent-wrapper --worktree "refactor the auth module"
+```
+
+Manual skill injection:
+
+```bash
+codeagent-wrapper --skills golang-base-practices "optimize database queries"
+```
+
+Parallel mode (task config from stdin):
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
 ---TASK---
 id: t1
 workdir: .
 backend: codex
 ---CONTENT---
-列出本项目的主要模块以及它们的职责。
+List the main modules and their responsibilities.

-## 支持的后端
+Use `--agent <name>` to select a preset. Agents inherit `base_url` / `api_key` from the corresponding `backends` entry.
 
-该项目本身不内置模型能力，依赖你本机安装并可在 `PATH` 中找到对应 CLI：
+### Dynamic Agents
 
-- `codex`：执行 `codex e ...`（默认会添加 `--dangerously-bypass-approvals-and-sandbox`；如需关闭请设置 `CODEX_BYPASS_SANDBOX=false`）
-- `claude`：执行 `claude -p ... --output-format stream-json`（默认会跳过权限提示；如需开启请设置 `CODEAGENT_SKIP_PERMISSIONS=false`）
-- `gemini`：执行 `gemini ... -o stream-json`（可从 `~/.gemini/.env` 加载环境变量）
-- `opencode`：执行 `opencode run --format json`
+Place a `{name}.md` file in `~/.codeagent/agents/` to use it via `--agent {name}`. The Markdown file is read as the prompt, using `default_backend` and `default_model`.

+| `codex` | `codex e ...` | Adds `--dangerously-bypass-approvals-and-sandbox` by default; set `CODEX_BYPASS_SANDBOX=false` to disable |
+| `claude` | `claude -p ... --output-format stream-json` | Skips permissions and disables setting-sources to prevent recursion; set `CODEAGENT_SKIP_PERMISSIONS=false` to enable prompts; auto-reads env and model from `~/.claude/settings.json` |
+| `gemini` | `gemini -o stream-json -y ...` | Auto-loads env vars from `~/.gemini/.env` (GEMINI_API_KEY, GEMINI_MODEL, etc.) |
+| `opencode` | `opencode run --format json` | — |

+```
+
+CI uses GitHub Actions with Go 1.21 / 1.22 matrix testing.
+
+## Troubleshooting
+
+- On macOS, if you see `permission denied` related to temp directories, set: `CODEAGENT_TMPDIR=$HOME/.codeagent/tmp`
+- `claude` backend's `base_url` / `api_key` (from `~/.codeagent/models.json` `backends.claude`) are injected as `ANTHROPIC_BASE_URL` / `ANTHROPIC_API_KEY` env vars
+- `gemini` backend's API key is loaded from `~/.gemini/.env`, injected as `GEMINI_API_KEY` with `GEMINI_API_KEY_AUTH_MECHANISM=bearer` auto-set
+- Exit codes: 127 = backend not found, 124 = timeout, 130 = interrupted
+- Parallel mode outputs structured summary by default; use `--full-output` for complete output when debugging

+# codeagent-wrapper
+
+[English](README.md) | [中文](README_CN.md)
+
+`codeagent-wrapper` 是一个用 Go 编写的多后端 AI 代码代理命令行包装器：用统一的 CLI 入口封装不同的 AI 工具后端（Codex / Claude / Gemini / OpenCode），并提供一致的参数、配置、技能注入与会话恢复体验。
+
+入口：`cmd/codeagent-wrapper/main.go`（生成二进制名：`codeagent-wrapper`）。
+
+## 功能特性
+
+- **多后端支持**：`codex` / `claude` / `gemini` / `opencode`
+- **统一命令行**：`codeagent-wrapper [flags] <task>` / `codeagent-wrapper resume <session_id> <task> [workdir]`
+- **自动 stdin**：遇到换行/特殊字符/超长任务自动走 stdin，避免 shell quoting 问题；也可显式使用 `-`
+- **配置合并**：支持配置文件与 `CODEAGENT_*` 环境变量（viper）
+- **Agent 预设**：从 `~/.codeagent/models.json` 读取 backend/model/prompt/reasoning/yolo/allowed_tools 等预设
+- **动态 Agent**：在 `~/.codeagent/agents/{name}.md` 放置 prompt 文件即可作为 agent 使用
+- **技能自动注入**：`--skills` 手动指定，或根据项目技术栈自动检测（Go/Rust/Python/Node.js/Vue）并注入对应技能规范
+- **Git Worktree 隔离**：`--worktree` 在独立 git worktree 中执行任务，自动生成 task_id 和分支
+- **并行执行**：`--parallel` 从 stdin 读取多任务配置，支持依赖拓扑并发执行，带结构化摘要报告
+- **后端配置**：`models.json` 的 `backends` 节支持 per-backend 的 `base_url` / `api_key` 注入
+- **Claude 工具控制**：`allowed_tools` / `disallowed_tools` 限制 Claude 后端可用工具
+- **Stderr 降噪**：自动过滤 Gemini 和 Codex 后端的噪声 stderr 输出
+- **日志清理**：`codeagent-wrapper cleanup` 清理旧日志（日志写入系统临时目录）
+- **跨平台**：支持 macOS / Linux / Windows
+
+## 安装
+
+### 推荐方式（交互式安装器）
+
+```bash
+npx github:cexll/myclaude
+```
+
+选择 `codeagent-wrapper` 模块进行安装。
+
+### 手动构建
+
+要求：Go 1.21+。
+
+```bash
+# 从源码构建
+make build
+
+# 或直接安装到 $GOPATH/bin
+make install
+```
+
+安装后确认：
+
+```bash
+codeagent-wrapper --version
+```
+
+## 使用示例
+
+最简单用法（默认后端：`codex`）：
+
+```bash
+codeagent-wrapper "分析 internal/app/cli.go 的入口逻辑，给出改进建议"
+```
+
+指定后端：
+
+```bash
+codeagent-wrapper --backend claude "解释 internal/executor/parallel_config.go 的并行配置格式"
+```
+
+指定工作目录（第 2 个位置参数）：
+
+```bash
+codeagent-wrapper "在当前 repo 下搜索潜在数据竞争" .
+```
+
+显式从 stdin 读取 task（使用 `-`）：
+
+```bash
+cat task.txt | codeagent-wrapper -
+```
+
+使用 HEREDOC（推荐用于多行任务）：
+
+```bash
+codeagent-wrapper --backend claude - <<'EOF'
+实现用户认证系统：
+- JWT 令牌
+- bcrypt 密码哈希
+- 会话管理
+EOF
+```
+
+恢复会话：
+
+```bash
+codeagent-wrapper resume <session_id> "继续上次任务"
+```
+
+在 git worktree 中隔离执行：
+
+```bash
+codeagent-wrapper --worktree "重构认证模块"
+```
+
+手动指定技能注入：
+
+```bash
+codeagent-wrapper --skills golang-base-practices "优化数据库查询"
+```
+
+并行模式（从 stdin 读取任务配置）：
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: t1
+workdir: .
+backend: codex
+---CONTENT---
+列出本项目的主要模块以及它们的职责。
+---TASK---
+id: t2
+dependencies: t1
+backend: claude
+---CONTENT---
+基于 t1 的结论，提出重构风险点与建议。

+
+## CLI 参数
+
+| 参数 | 说明 |
+|------|------|
+| `--backend <name>` | 后端选择（codex/claude/gemini/opencode） |
+| `--model <name>` | 覆盖模型 |
+| `--agent <name>` | Agent 预设名（来自 models.json 或 ~/.codeagent/agents/） |
+| `--prompt-file <path>` | 从文件读取 prompt |
+| `--skills <names>` | 逗号分隔的技能名，注入对应规范 |
+| `--reasoning-effort <level>` | 推理力度（后端相关） |
+| `--skip-permissions` | 跳过权限提示 |
+| `--dangerously-skip-permissions` | `--skip-permissions` 的别名 |
+| `--worktree` | 在新 git worktree 中执行（自动生成 task_id） |
+| `--parallel` | 并行任务模式（从 stdin 读取配置） |
+| `--full-output` | 并行模式下输出完整消息（默认仅输出摘要） |
+| `--config <path>` | 配置文件路径（默认：`$HOME/.codeagent/config.*`） |
+| `--version`, `-v` | 打印版本号 |
+| `--cleanup` | 清理旧日志 |
+
+## 配置说明
+
+### 配置文件
+
+默认查找路径（当 `--config` 为空时）：
+
+- `$HOME/.codeagent/config.(yaml|yml|json|toml|...)`
+
+示例（YAML）：
+
+```yaml
+backend: codex
+model: gpt-4.1
+skip-permissions: false
+```
+
+也可以通过 `--config /path/to/config.yaml` 显式指定。
+
+### 环境变量（`CODEAGENT_*`）
+
+通过 viper 读取并自动映射 `-` 为 `_`，常用项：
+
+| 变量 | 说明 |
+|------|------|
+| `CODEAGENT_BACKEND` | 后端名（codex/claude/gemini/opencode） |
+| `CODEAGENT_MODEL` | 模型名 |
+| `CODEAGENT_AGENT` | Agent 预设名 |
+| `CODEAGENT_PROMPT_FILE` | Prompt 文件路径 |
+| `CODEAGENT_REASONING_EFFORT` | 推理力度 |
+| `CODEAGENT_SKIP_PERMISSIONS` | 跳过权限提示（默认 true；设 `false` 关闭） |
+| `CODEAGENT_FULL_OUTPUT` | 并行模式完整输出 |
+| `CODEAGENT_MAX_PARALLEL_WORKERS` | 并行 worker 数（0=不限制，上限 100） |
+| `CODEAGENT_TMPDIR` | 自定义临时目录（macOS 权限问题时使用） |
+| `CODEX_TIMEOUT` | 超时（毫秒，默认 7200000 即 2 小时） |
+| `CODEX_BYPASS_SANDBOX` | Codex sandbox bypass（默认 true；设 `false` 关闭） |
+| `DO_WORKTREE_DIR` | 复用已有 worktree 目录（由 /do 工作流设置） |
+
+### Agent 预设（`~/.codeagent/models.json`）
+
+```json
+{
+  "default_backend": "codex",
+  "default_model": "gpt-4.1",
+  "backends": {
+    "codex": { "api_key": "..." },
+    "claude": { "base_url": "http://localhost:23001", "api_key": "..." }
+  },
+  "agents": {
+    "develop": {
+      "backend": "codex",
+      "model": "gpt-4.1",
+      "prompt_file": "~/.codeagent/prompts/develop.md",
+      "reasoning": "high",
+      "yolo": true,
+      "allowed_tools": ["Read", "Write", "Bash"],
+      "disallowed_tools": ["WebFetch"]
+    }
+  }
+}
+```
+
+用 `--agent <name>` 选择预设，agent 会继承 `backends` 下对应后端的 `base_url` / `api_key`。
+
+### 动态 Agent
+
+在 `~/.codeagent/agents/` 目录放置 `{name}.md` 文件，即可通过 `--agent {name}` 使用，自动读取该 Markdown 作为 prompt，使用 `default_backend` 和 `default_model`。
+
+### 技能自动检测
+
+当未通过 `--skills` 显式指定技能时，codeagent-wrapper 会根据工作目录中的文件自动检测技术栈：
+
+| 检测文件 | 注入技能 |
+|----------|----------|
+| `go.mod` / `go.sum` | `golang-base-practices` |
+| `Cargo.toml` | `rust-best-practices` |
+| `pyproject.toml` / `setup.py` / `requirements.txt` | `python-best-practices` |
+| `package.json` | `vercel-react-best-practices`, `frontend-design` |
+| `vue.config.js` / `vite.config.ts` / `nuxt.config.ts` | `vue-web-app` |
+
+技能规范从 `~/.claude/skills/{name}/SKILL.md` 读取，受 16000 字符预算限制。
+
+## 支持的后端
+
+该项目本身不内置模型能力，依赖本机安装并可在 `PATH` 中找到对应 CLI：
+
+| 后端 | 执行命令 | 说明 |
+|------|----------|------|
+| `codex` | `codex e ...` | 默认添加 `--dangerously-bypass-approvals-and-sandbox`；设 `CODEX_BYPASS_SANDBOX=false` 关闭 |
+| `claude` | `claude -p ... --output-format stream-json` | 默认跳过权限并禁用 setting-sources 防止递归；设 `CODEAGENT_SKIP_PERMISSIONS=false` 开启权限；自动读取 `~/.claude/settings.json` 中的 env 和 model |
+| `gemini` | `gemini -o stream-json -y ...` | 自动从 `~/.gemini/.env` 加载环境变量（GEMINI_API_KEY, GEMINI_MODEL 等） |
+| `opencode` | `opencode run --format json` | — |

-name: codex
-description: Execute Codex CLI for code analysis, refactoring, and automated code changes. Use when you need to delegate complex code tasks to Codex AI with file references (@syntax) and structured output.
----
-
-# Codex CLI Integration
-
-## Overview
-
-Execute Codex CLI commands and parse structured JSON responses. Supports file references via `@` syntax, multiple models, and sandbox controls.
-
-## When to Use
-
-- Complex code analysis requiring deep understanding
-- Large-scale refactoring across multiple files
-- Automated code generation with safety controls
-
-## Fallback Policy
-
-Codex is the **primary execution method** for all code edits and tests. Direct execution is only permitted when:
-
-1. Codex is unavailable (service down, network issues)
-2. Codex fails **twice consecutively** on the same task
-
-When falling back to direct execution:
-- Log `CODEX_FALLBACK` with the reason
-- Retry Codex on the next task (don't permanently switch)
-- Document the fallback in the final summary
-
-## Usage
-
-**Mandatory**: Run every automated invocation through the Bash tool in the foreground with **HEREDOC syntax** to avoid shell quoting issues, keeping the `timeout` parameter fixed at `7200000` milliseconds (do not change it or use any other entry point).
-
-```bash
-codex-wrapper - [working_dir] <<'EOF'
-<task content here>
-EOF
-```
-
-**Why HEREDOC?** Tasks often contain code blocks, nested quotes, shell metacharacters (`$`, `` ` ``, `\`), and multiline text. HEREDOC (Here Document) syntax passes these safely without shell interpretation, eliminating quote-escaping nightmares.
-
-**Foreground only (no background/BashOutput)**: Never set `background: true`, never accept Claude's "Running in the background" mode, and avoid `BashOutput` streaming loops. Keep a single foreground Bash call per Codex task; if work might be long, split it into smaller foreground runs instead of offloading to background execution.
-
-**Simple tasks** (backward compatibility):
-For simple single-line tasks without special characters, you can still use direct quoting:
-```bash
-codex-wrapper "simple task here" [working_dir]
-```
-
-**Resume a session with HEREDOC:**
-```bash
-codex-wrapper resume <session_id> - [working_dir] <<'EOF'
-<task content>
-EOF
-```
-
-**Cross-platform notes:**
-- **Bash/Zsh**: Use `<<'EOF'` (single quotes prevent variable expansion)
-- **PowerShell 5.1+**: Use `@'` and `'@` (here-string syntax)
-  ```powershell
-  codex-wrapper - @'
-  task content
-  '@
-  ```
-
-## Environment Variables
-
-- **CODEX_TIMEOUT**: Override timeout in milliseconds (default: 7200000 = 2 hours)
-  - Example: `export CODEX_TIMEOUT=3600000` for 1 hour
-
-## Timeout Control
-
-- **Built-in**: Binary enforces 2-hour timeout by default
-- **Override**: Set `CODEX_TIMEOUT` environment variable (in milliseconds, e.g., `CODEX_TIMEOUT=3600000` for 1 hour)
-- **Behavior**: On timeout, sends SIGTERM, then SIGKILL after 5s if process doesn't exit
-- **Exit code**: Returns 124 on timeout (consistent with GNU timeout)
-- **Bash tool**: Always set `timeout: 7200000` parameter for double protection
-
-### Parameters
-
-- `task` (required): Task description, supports `@file` references
-- `working_dir` (optional): Working directory (default: current)
-
-### Return Format
-
-Extracts `agent_message` from Codex JSON stream and appends session ID:
-```
-Agent response text here...
-
----
-SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
-```
-
-Error format (stderr):
-```
-ERROR: Error message
-```
-
-Return only the final agent message and session ID—do not paste raw `BashOutput` logs or background-task chatter into the conversation.
-
-### Invocation Pattern
-
-All automated executions must use HEREDOC syntax through the Bash tool in the foreground, with `timeout` fixed at `7200000` (non-negotiable):
-
-```
-Bash tool parameters:
-- command: codex-wrapper - [working_dir] <<'EOF'
-  <task content>
-  EOF
-- timeout: 7200000
-- description: <brief description of the task>
-```
-
-Run every call in the foreground—never append `&` to background it—so logs and errors stay visible for timely interruption or diagnosis.
-
-**Important:** Use HEREDOC (`<<'EOF'`) for all but the simplest tasks. This prevents shell interpretation of quotes, variables, and special characters.
-
-### Examples
-
-**Basic code analysis:**
-```bash
-# Recommended: with HEREDOC (handles any special characters)
-codex-wrapper - <<'EOF'
-explain @src/main.ts
-EOF
-# timeout: 7200000
-
-# Alternative: simple direct quoting (if task is simple)
-codex-wrapper "explain @src/main.ts"
-```
-
-**Refactoring with multiline instructions:**
-```bash
-codex-wrapper - <<'EOF'
-refactor @src/utils for performance:
-- Extract duplicate code into helpers
-- Use memoization for expensive calculations
-- Add inline comments for non-obvious logic
-EOF
-# timeout: 7200000
-```
-
-**Multi-file analysis:**
-```bash
-codex-wrapper - "/path/to/project" <<'EOF'
-analyze @. and find security issues:
-1. Check for SQL injection vulnerabilities
-2. Identify XSS risks in templates
-3. Review authentication/authorization logic
-4. Flag hardcoded credentials or secrets
-EOF
-# timeout: 7200000
-```
-
-**Resume previous session:**
-```bash
-# First session
-codex-wrapper - <<'EOF'
-add comments to @utils.js explaining the caching logic
-EOF
-# Output includes: SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
-
-# Continue the conversation with more context
-codex-wrapper resume 019a7247-ac9d-71f3-89e2-a823dbd8fd14 - <<'EOF'
-now add TypeScript type hints and handle edge cases where cache is null
-EOF
-# timeout: 7200000
-```
-
-**Task with code snippets and special characters:**
-```bash
-codex-wrapper - <<'EOF'
-Fix the bug in @app.js where the regex /\d+/ doesn't match "123"
-The current code is:
-  const re = /\d+/;
-  if (re.test(input)) { ... }
-Add proper escaping and handle $variables correctly.
-EOF
-```
-
-### Parallel Execution
-
-> Important:
-> - `--parallel` only reads task definitions from stdin.
-> - It does not accept extra command-line arguments (no inline `workdir`, `task`, or other params).
-> - Put all task metadata and content in stdin; nothing belongs after `--parallel` on the command line.
-
-**Correct vs Incorrect Usage**
-
-**Correct:**
-```bash
-# Option 1: file redirection
-codex-wrapper --parallel < tasks.txt
-
-# Option 2: heredoc (recommended for multiple tasks)
-codex-wrapper --parallel <<'EOF'
----TASK---
-id: task1
-workdir: /path/to/dir
----CONTENT---
-task content
-EOF
-
-# Option 3: pipe
-echo "---TASK---..." | codex-wrapper --parallel
-```
-
-**Incorrect (will trigger shell parsing errors):**
-```bash
-# Bad: no extra args allowed after --parallel
-codex-wrapper --parallel - /path/to/dir <<'EOF'
-...
-EOF
-
-# Bad: --parallel does not take a task argument
-codex-wrapper --parallel "task description"
-
-# Bad: workdir must live inside the task config
-codex-wrapper --parallel /path/to/dir < tasks.txt
-```
-
-For multiple independent or dependent tasks, use `--parallel` mode with delimiter format:
-
-**Typical Workflow (analyze → implement → test, chained in a single parallel call)**:
-```bash
-codex-wrapper --parallel <<'EOF'
----TASK---
-id: analyze_1732876800
-workdir: /home/user/project
----CONTENT---
-analyze @spec.md and summarize API and UI requirements
----TASK---
-id: implement_1732876801
-workdir: /home/user/project
-dependencies: analyze_1732876800
----CONTENT---
-implement features from analyze_1732876800 summary in backend @services and frontend @ui
----TASK---
-id: test_1732876802
-workdir: /home/user/project
-dependencies: implement_1732876801
----CONTENT---
-add and run regression tests covering the new endpoints and UI flows
-EOF
-```
-A single `codex-wrapper --parallel` call schedules all three stages concurrently, using `dependencies` to enforce sequential ordering without multiple invocations.
-
-```bash
-codex-wrapper --parallel <<'EOF'
----TASK---
-id: backend_1732876800
-workdir: /home/user/project/backend
----CONTENT---
-implement /api/orders endpoints with validation and pagination
----TASK---

-dependencies: backend_1732876800, frontend_1732876801
----CONTENT---
-run API contract tests and UI smoke tests (waits for backend+frontend)
-EOF
-```
-
-**Delimiter Format**:
-- `---TASK---`: Starts a new task block
-- `id: <task-id>`: Required, unique task identifier
-  - Best practice: use `<feature>_<timestamp>` format (e.g., `auth_1732876800`, `api_test_1732876801`)
-  - Ensures uniqueness across runs and makes tasks traceable
-- `workdir: <path>`: Optional, working directory (default: `.`)
-  - Best practice: use absolute paths (e.g., `/home/user/project/backend`)
-  - Avoids ambiguity and ensures consistent behavior across environments
-  - Must be specified inside each task block; do not pass `workdir` as a CLI argument to `--parallel`
-  - Each task can set its own `workdir` when different directories are needed
-- `dependencies: <id1>, <id2>`: Optional, comma-separated task IDs
-- `session_id: <uuid>`: Optional, resume a previous session
-- `---CONTENT---`: Separates metadata from task content
-- Task content: Any text, code, special characters (no escaping needed)
-
-**Dependencies Best Practices**
-
-- Avoid multiple invocations: Place "analyze then implement" in a single `codex-wrapper --parallel` call, chaining them via `dependencies`, rather than running analysis first and then launching implementation separately.
-- Naming convention: Use `<action>_<timestamp>` format (e.g., `analyze_1732876800`, `implement_1732876801`), where action names map to features/stages and timestamps ensure uniqueness and sortability.
-- Dependency chain design: Keep chains short; only add dependencies for tasks that truly require ordering, let others run in parallel, avoiding over-serialization that reduces throughput.
-
-**Resume Failed Tasks**:
-```bash
-# Use session_id from previous output to resume
-codex-wrapper --parallel <<'EOF'
----TASK---
-id: T2
-session_id: 019xxx-previous-session-id
----CONTENT---
-fix the previous error and retry
-EOF
-```
-
-**Output**: Human-readable text format
-```
-=== Parallel Execution Summary ===
-Total: 3 | Success: 2 | Failed: 1
-
---- Task: T1 ---
-Status: SUCCESS
-Session: 019xxx
-
-Task output message...
-
---- Task: T2 ---
-Status: FAILED (exit code 1)
-Error: some error message
-```
-
-**Features**:
-- Automatic topological sorting based on dependencies
-- Unlimited concurrency for independent tasks
-- Error isolation (failed tasks don't stop others)
-- Dependency blocking (dependent tasks skip if parent fails)
-
-## Notes
-
-- **Binary distribution**: Single Go binary, zero dependencies
-- **Installation**: Download from GitHub Releases or use install.sh
-- **Cross-platform compatible**: Linux (amd64/arm64), macOS (amd64/arm64)
-- All automated runs must use the Bash tool with the fixed timeout to provide dual timeout protection and unified logging/exit semantics
-for automation (new sessions only)
-- Uses `--skip-git-repo-check` to work in any directory
-- Streams progress, returns only final agent message
-- Every execution returns a session ID for resuming conversations
-- Requires Codex CLI installed and authenticated

-description: Execute Gemini CLI for AI-powered code analysis and generation. Use when you need to leverage Google's Gemini models for complex reasoning tasks.
----
-
-# Gemini CLI Integration
-
-## Overview
-
-Execute Gemini CLI commands with support for multiple models and flexible prompt input. Integrates Google's Gemini AI models into Claude Code workflows.
-
-## When to Use
-
-- Complex reasoning tasks requiring advanced AI capabilities
-- Code generation and analysis with Gemini models
-- Tasks requiring Google's latest AI technology
-- Alternative perspective on code problems
-
-## Usage
-**Mandatory**: Run via uv with fixed timeout 7200000ms (foreground):
-```bash
-uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
-```
-
-**Optional** (direct execution or using Python):
-```bash
-~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
-# or
-python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
-```
-
-## Environment Variables
-
-- **GEMINI_MODEL**: Configure model (default: `gemini-3-pro-preview`)
-  - Example: `export GEMINI_MODEL=gemini-3`
-
-## Timeout Control
-
-- **Fixed**: 7200000 milliseconds (2 hours), immutable
-- **Bash tool**: Always set `timeout: 7200000` for double protection
-
-### Parameters
-
-- `prompt` (required): Task prompt or question
-- `working_dir` (optional): Working directory (default: current directory)
-
-### Return Format
-
-Plain text output from Gemini:
-
-```text
-Model response text here...
-```
-
-Error format (stderr):
-
-```text
-ERROR: Error message
-```
-
-### Invocation Pattern
-
-When calling via Bash tool, always include the timeout parameter:
-
-```yaml
-Bash tool parameters:
-- command: uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
-- timeout: 7200000
-- description: <brief description of the task>
-```
-
-Alternatives:
-
-```yaml
-# Direct execution (simplest)
-- command: ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
-
-# Using python3
-- command: python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
-```
-
-### Examples
-
-**Basic query:**
-
-```bash
-uv run ~/.claude/skills/gemini/scripts/gemini.py "explain quantum computing"
-# timeout: 7200000
-```
-
-**Code analysis:**
-
-```bash
-uv run ~/.claude/skills/gemini/scripts/gemini.py "review this code for security issues: $(cat app.py)"
-# timeout: 7200000
-```
-
-**With specific working directory:**
-
-```bash
-uv run ~/.claude/skills/gemini/scripts/gemini.py "analyze project structure" "/path/to/project"
-# timeout: 7200000
-```
-
-**Using python3 directly (alternative):**
-
-```bash
-python3 ~/.claude/skills/gemini/scripts/gemini.py "your prompt here"
-```
-
-## Notes
-
-- **Recommended**: Use `uv run` for automatic Python environment management (requires uv installed)
-- **Alternative**: Direct execution `./gemini.py` (uses system Python via shebang)
-- Python implementation using standard library (zero dependencies)
-- Cross-platform compatible (Windows/macOS/Linux)
-- PEP 723 compliant (inline script metadata)
-- Requires Gemini CLI installed and authenticated
-- Supports all Gemini model variants (configure via `GEMINI_MODEL` environment variable)
-- Output is streamed directly from Gemini CLI

+description: "This skill should be used for multi-session autonomous agent work requiring progress checkpointing, failure recovery, and task dependency management. Triggers on '/harness' command, or when a task involves many subtasks needing progress persistence, sleep/resume cycles across context windows, recovery from mid-task failures with partial state, or distributed work across multiple agent sessions. Synthesized from Anthropic and OpenAI engineering practices for long-running agents."
+---
+
+# Harness — Long-Running Agent Framework
+
+Executable protocol enabling any agent task to run continuously across multiple sessions with automatic progress recovery, task dependency resolution, failure rollback, and standardized error handling.
+
+## Design Principles
+
+1. **Design for the agent, not the human** — Test output, docs, and task structure are the agent's primary interface
+2. **Progress files ARE the context** — When context window resets, progress files + git history = full recovery
+3. **Premature completion is the #1 failure mode** — Structured task lists with explicit completion criteria prevent declaring victory early
+4. **Standardize everything grep-able** — ERROR on same line, structured timestamps, consistent prefixes
+5. **Fast feedback loops** — Pre-compute stats, run smoke tests before full validation
+6. **Idempotent everything** — Init scripts, task execution, environment setup must all be safe to re-run
+7. **Fail safe, not fail silent** — Every failure must have an explicit recovery strategy
+
+## Commands
+
+```
+/harness init <project-path>     # Initialize harness files in project
+/harness run                     # Start/resume the infinite loop
+/harness status                  # Show current progress and stats
+/harness add "task description"  # Add a task to the list
+```
+
+## Progress Persistence (Dual-File System)
+
+Maintain two files in the project working directory:
+
+### harness-progress.txt (Append-Only Log)
+
+Free-text log of all agent actions across sessions. Never truncate.

+
+Task statuses: `pending` → `in_progress` (transient, set only during active execution) → `completed` or `failed`. A task found as `in_progress` at session start means the previous session was interrupted — handle via Context Window Recovery Protocol.
+
+**Session boundary**: A session starts when the agent begins executing the Session Start protocol and ends when a Stopping Condition is met or the context window resets. Each session gets a unique `SESSION-N` identifier (N = `session_count` after increment).
+
+## Concurrency Control
+
+Before modifying `harness-tasks.json`, acquire an exclusive lock using portable `mkdir` (atomic on all POSIX systems, works on both macOS and Linux):
+
+```bash
+# Acquire lock (fail fast if another agent is running)
+LOCKDIR="/tmp/harness-$(printf '%s' "$(pwd)" | shasum -a 256 2>/dev/null || sha256sum | cut -c1-8).lock"
+if ! mkdir "$LOCKDIR" 2>/dev/null; then
+  # Check if lock holder is still alive
+  LOCK_PID=$(cat "$LOCKDIR/pid" 2>/dev/null)
+  if [ -n "$LOCK_PID" ] && kill -0 "$LOCK_PID" 2>/dev/null; then
+    echo "ERROR: Another harness session is active (pid=$LOCK_PID)"; exit 1
+  fi
+  # Stale lock — atomically reclaim via mv to avoid TOCTOU race
+  STALE="$LOCKDIR.stale.$$"
+  if mv "$LOCKDIR" "$STALE" 2>/dev/null; then
+    rm -rf "$STALE"
+    mkdir "$LOCKDIR" || { echo "ERROR: Lock contention"; exit 1; }
+    echo "WARN: Removed stale lock${LOCK_PID:+ from pid=$LOCK_PID}"
+  else
+    echo "ERROR: Another agent reclaimed the lock"; exit 1
+  fi
+fi
+echo "$$" > "$LOCKDIR/pid"
+trap 'rm -rf "$LOCKDIR"' EXIT
+```
+
+Log lock acquisition: `[timestamp] [SESSION-N] LOCK acquired (pid=<PID>)`
+Log lock release: `[timestamp] [SESSION-N] LOCK released`
+
+The lock is held for the entire session. The `trap EXIT` handler releases it automatically on normal exit, errors, or signals. Never release the lock between tasks within a session.
+
+## Infinite Loop Protocol
+
+### Session Start (Execute Every Time)
+
+1. **Read state**: Read last 200 lines of `harness-progress.txt` + full `harness-tasks.json`. If JSON is unparseable, see JSON corruption recovery in Error Handling.
+2. **Read git**: Run `git log --oneline -20` and `git diff --stat` to detect uncommitted work
+3. **Acquire lock**: Fail if another session is active
+4. **Recover interrupted tasks** (see Context Window Recovery below)
+5. **Health check**: Run `harness-init.sh` if it exists
+6. **Track session**: Increment `session_count` in JSON. Check `session_count` against `max_sessions` — if reached, log STATS and STOP. Initialize per-session task counter to 0.
+7. **Pick next task** using Task Selection Algorithm below
+
+### Task Selection Algorithm
+
+Before selecting, run dependency validation:
+
+1. **Cycle detection**: For each non-completed task, walk `depends_on` transitively. If any task appears in its own chain, mark it `failed` with `[DEPENDENCY] Circular dependency detected: task-A -> task-B -> task-A`. Self-references (`depends_on` includes own id) are also cycles.
+2. **Blocked propagation**: If a task's `depends_on` includes a task that is `failed` and will never be retried (either `attempts >= max_attempts` OR its `error_log` contains a `[DEPENDENCY]` entry), mark the blocked task as `failed` with `[DEPENDENCY] Blocked by failed task-XXX`. Repeat until no more tasks can be propagated.
+
+Then pick the next task in this priority order:
+
+1. Tasks with `status: "pending"` where ALL `depends_on` tasks are `completed` — sorted by `priority` (P0 > P1 > P2), then by `id` (lowest first)
+2. Tasks with `status: "failed"` where `attempts < max_attempts` and ALL `depends_on` are `completed` — sorted by priority, then oldest failure first
+3. If no eligible tasks remain → log final STATS → STOP
+
+### Task Execution Cycle
+
+For each task, execute this exact sequence:
+
+1. **Claim**: Record `started_at_commit` = current HEAD hash. Set status to `in_progress`, log `Starting [<task-id>] <title> (base=<hash>)`
+2. **Execute with checkpoints**: Perform the work. After each significant step, log:
+   ```
+   [timestamp] [SESSION-N] CHECKPOINT [task-id] step=M/N "description of what was done"
+   ```
+   Also append to the task's `checkpoints` array: `{ "step": M, "total": N, "description": "...", "timestamp": "ISO" }`
+3. **Validate**: Run the task's `validation.command` wrapped with `timeout`: `timeout <timeout_seconds> <command>`. If no validation command, skip. Before running, verify the command exists (e.g., `command -v <binary>`) — if missing, treat as `ENV_SETUP` error.
+   - Command exits 0 → PASS
+   - Command exits non-zero → FAIL
+   - Command exceeds timeout → TIMEOUT
+4. **Record outcome**:
+   - **Success**: status=`completed`, set `completed_at`, log `Completed [<task-id>] (commit <hash>)`, git commit
+   - **Failure**: increment `attempts`, append error to `error_log`. Verify `started_at_commit` exists via `git cat-file -t <hash>` — if missing, mark failed at max_attempts. Otherwise execute `git reset --hard <started_at_commit>` and `git clean -fd` to rollback ALL commits and remove untracked files. Execute `on_failure.cleanup` if defined. Log `ERROR [<task-id>] [<category>] <message>`. Set status=`failed` (Task Selection Algorithm pass 2 handles retries when attempts < max_attempts)
+5. **Track**: Increment per-session task counter. If `max_tasks_per_session` reached, log STATS and STOP.
+6. **Continue**: Immediately pick next task (zero idle time)
+
+### Stopping Conditions
+
+- All tasks `completed`
+- All remaining tasks `failed` at max_attempts or blocked by failed dependencies
+- `session_config.max_tasks_per_session` reached for this session
+- `session_config.max_sessions` reached across all sessions
+- User interrupts
+
+## Context Window Recovery Protocol
+
+When a new session starts and finds a task with `status: "in_progress"`:
+
+1. **Check git state**:
+   ```bash
+   git diff --stat          # Uncommitted changes?
+   git log --oneline -5     # Recent commits since task started?
+   git stash list           # Any stashed work?
+   ```
+2. **Check checkpoints**: Read the task's `checkpoints` array to determine last completed step
+3. **Decision matrix** (verify recent commits belong to this task by checking commit messages for the task-id):
+
+| Uncommitted? | Recent task commits? | Checkpoints? | Action |
+|---|---|---|---|
+| No | No | None | Mark `failed` with `[SESSION_TIMEOUT] No progress detected`, increment attempts |
+| No | No | Some | Verify file state matches checkpoint claims. If files reflect checkpoint progress, resume from last step. If not, mark `failed` — work was lost |
+| No | Yes | Any | Run `validation.command`. If passes → mark `completed`. If fails → `git reset --hard <started_at_commit>`, mark `failed` |
+| Yes | No | Any | Run validation WITH uncommitted changes present. If passes → commit, mark `completed`. If fails → `git reset --hard <started_at_commit>` + `git clean -fd`, mark `failed` |
+| Yes | Yes | Any | Commit uncommitted changes, run `validation.command`. If passes → mark `completed`. If fails → `git reset --hard <started_at_commit>` + `git clean -fd`, mark `failed` |
+
+4. **Log recovery**: `[timestamp] [SESSION-N] RECOVERY [task-id] action="<action taken>" reason="<reason>"`
+
+## Error Handling & Recovery Strategies
+
+Each error category has a default recovery strategy:
+
+| Category | Default Recovery | Agent Action |
+|----------|-----------------|--------------|
+| `ENV_SETUP` | Re-run init, then STOP if still failing | Run `harness-init.sh` again immediately. If fails twice, log and stop — environment is broken |
+| `TASK_EXEC` | Rollback via `git reset --hard <started_at_commit>`, retry | Verify `started_at_commit` exists (`git cat-file -t <hash>`). If missing, mark failed at max_attempts. Otherwise reset, run `on_failure.cleanup` if defined, retry if attempts < max_attempts |
+| `TEST_FAIL` | Rollback via `git reset --hard <started_at_commit>`, retry | Reset to `started_at_commit`, analyze test output to identify fix, retry with targeted changes |
+| `TIMEOUT` | Kill process, execute cleanup, retry | Wrap validation with `timeout <seconds> <command>`. On timeout, run `on_failure.cleanup`, retry (consider splitting task if repeated) |
+| `DEPENDENCY` | Skip task, mark blocked | Log which dependency failed, mark task as `failed` with dependency reason |
+| `SESSION_TIMEOUT` | Use Context Window Recovery Protocol | New session assesses partial progress via Recovery Protocol — may result in completion or failure depending on validation |
+
+**JSON corruption**: If `harness-tasks.json` cannot be parsed, check for `harness-tasks.json.bak` (written before each modification). If backup exists and is valid, restore from it. If no valid backup, log `ERROR [ENV_SETUP] harness-tasks.json corrupted and unrecoverable` and STOP — task metadata (validation commands, dependencies, cleanup) cannot be reconstructed from logs alone.
+
+**Backup protocol**: Before every write to `harness-tasks.json`, copy the current file to `harness-tasks.json.bak`.
+
+## Environment Initialization
+
+If `harness-init.sh` exists in the project root, run it at every session start. The script must be idempotent.
+
+Example `harness-init.sh`:
+```bash
+#!/bin/bash
+set -e
+npm install 2>/dev/null || pip install -r requirements.txt 2>/dev/null || true
+curl -sf http://localhost:5432 >/dev/null 2>&1 || echo "WARN: DB not reachable"
+npm test -- --bail --silent 2>/dev/null || echo "WARN: Smoke test failed"
+echo "Environment health check complete"
+```
+
+## Standardized Log Format
+
+All log entries use grep-friendly format on a single line:
+
+```
+[ISO-timestamp] [SESSION-N] <TYPE> [task-id]? [category]? message
+```
+
+`[task-id]` and `[category]` are included when applicable (task-scoped entries). Session-level entries (`INIT`, `LOCK`, `STATS`) omit them.
+
+Types: `INIT`, `Starting`, `Completed`, `ERROR`, `CHECKPOINT`, `ROLLBACK`, `RECOVERY`, `STATS`, `LOCK`, `WARN`
+
+Error categories: `ENV_SETUP`, `TASK_EXEC`, `TEST_FAIL`, `TIMEOUT`, `DEPENDENCY`, `SESSION_TIMEOUT`
+
+Filtering:
+```bash
+grep "ERROR" harness-progress.txt                    # All errors
+grep "ERROR" harness-progress.txt | grep "TASK_EXEC" # Execution errors only
+grep "SESSION-3" harness-progress.txt                # All session 3 activity
+grep "STATS" harness-progress.txt                    # All session summaries
+grep "CHECKPOINT" harness-progress.txt               # All checkpoints
+grep "RECOVERY" harness-progress.txt                 # All recovery actions
+```
+
+## Session Statistics
+
+At session end, update `harness-tasks.json`: increment `session_count`, set `last_session` to current timestamp. Then append:
+
+```
+[timestamp] [SESSION-N] STATS tasks_total=10 completed=7 failed=1 pending=2 blocked=0 attempts_total=12 checkpoints=23
+```
+
+`blocked` is computed at stats time: count of pending tasks whose `depends_on` includes a permanently failed task. It is not a stored status value.
+
+## Init Command (`/harness init`)
+
+1. Create `harness-progress.txt` with initialization entry
+2. Create `harness-tasks.json` with empty task list and default `session_config`
+3. Optionally create `harness-init.sh` template (chmod +x)
+4. Ask user: add harness files to `.gitignore`?
+
+## Status Command (`/harness status`)
+
+Read `harness-tasks.json` and `harness-progress.txt`, then display:
+
+1. Task summary: count by status (completed, failed, pending, blocked). `blocked` = pending tasks whose `depends_on` includes a permanently failed task (computed, not a stored status).
+2. Per-task one-liner: `[status] task-id: title (attempts/max_attempts)`
+3. Last 5 lines from `harness-progress.txt`
+4. Session count and last session timestamp
+
+Does NOT acquire the lock (read-only operation).
+
+## Add Command (`/harness add`)
+
+Append a new task to `harness-tasks.json` with auto-incremented id (`task-NNN`), status `pending`, default `max_attempts: 3`, empty `depends_on`, and no validation command. Prompt user for optional fields: `priority`, `depends_on`, `validation.command`, `timeout_seconds`. Requires lock acquisition (modifies JSON).
+
+## Tool Dependencies
+
+Requires: Bash, file read/write, git. All harness operations must be executed from the project root directory.
+Does NOT require: specific MCP servers, programming languages, or test frameworks.
