 # Changelog

-## 5.2.0 - 2025-12-11
- PR #53: unified CLI version source in `codeagent-wrapper/main.go` and bumped to 5.2.0.
- Added legacy `codex-wrapper` alias support (runtime detection plus `scripts/install.sh` symlink helper).
- Updated documentation to reflect backend flag usage and new version output.
+## 5.2.0 - 2025-12-13
+
+### 🚀 Core Features
+
+#### Skills System Enhancements
+- **New Skills**: Added `codeagent`, `product-requirements`, `prototype-prompt-generator` to `skill-rules.json`
+- **Auto-Activation**: Skills automatically trigger based on keyword/pattern matching via hooks
+- **Backward Compatibility**: Retained `skills/codex/SKILL.md` for existing workflows
+
+#### Multi-Backend Support (codeagent-wrapper)
+- **Renamed**: `codex-wrapper` → `codeagent-wrapper` with pluggable backend architecture
+- **Three Backends**: Codex (default), Claude, Gemini via `--backend` flag
+- **Smart Parser**: Auto-detects backend JSON stream formats
+- **Session Resume**: All backends support `-r <session_id>` cross-session resume
+- **Parallel Execution**: DAG task scheduling with global and per-task backend configuration
+- **Concurrency Control**: `CODEAGENT_MAX_PARALLEL_WORKERS` env var limits concurrent tasks (max 100)
+- **Test Coverage**: 93.4% (backend.go 100%, config.go 97.8%, executor.go 96.4%)
+
+#### Dev Workflow
+- **`/dev`**: 6-step minimal dev workflow with mandatory 90% test coverage
+
+#### Hooks System
+- **UserPromptSubmit**: Auto-activate skills based on context
+- **PostToolUse**: Auto-validation/formatting after tool execution
+- **Stop**: Cleanup and reporting on session end
+- **Examples**: Skill auto-activation, pre-commit checks
+
+#### Skills System
+- **Auto-Activation**: `skill-rules.json` regex trigger rules
+- **codeagent skill**: Multi-backend wrapper integration
+- **Modular Design**: Easy to extend with custom skills
+
+#### Installation System Enhancements
+- **`merge_json` operation**: Auto-merge `settings.json` configuration
+- **Modular Installation**: `python3 install.py --module dev`
+- **Verbose Logging**: `--verbose/-v` enables terminal real-time output
+- **Streaming Output**: `op_run_command` streams bash script execution
+- **Configuration Cleanup**: Removed deprecated `gh` module from `config.json`
+
+### 📚 Documentation
+
+- `docs/architecture.md` (21KB): Architecture overview with ASCII diagrams
+- `docs/CODEAGENT-WRAPPER.md` (9KB): Complete usage guide
+- `docs/HOOKS.md` (4KB): Customization guide
+- `README.md`: Added documentation index, corrected default backend description
+
+### 🔧 Important Fixes
+
+#### codeagent-wrapper
+- Fixed Claude/Gemini backend `-C` (workdir) and `-r` (resume) parameter support (codeagent-wrapper/backend.go:80-120)
+- Corrected Claude backend permission flag logic `if cfg.SkipPermissions` (codeagent-wrapper/backend.go:95)
+- Fixed parallel mode startup banner duplication (codeagent-wrapper/main.go:184-194 removed)
+- Extract and display recent errors on abnormal exit `Logger.ExtractRecentErrors()` (codeagent-wrapper/logger.go:156)
+- Added task block index to parallel config error messages (codeagent-wrapper/config.go:245)
+- Refactored signal handling logic to avoid duplicate nil checks (codeagent-wrapper/main.go:290-305)
+- Removed binary artifacts from tracking (codeagent-wrapper, *.test, coverage.out)
+
+#### Installation Scripts
+- Fixed issue #55: `op_run_command` uses Popen + selectors for real-time streaming output
+- Fixed issue #56: Display recent errors instead of entire log
+- Changed module list header from "Enabled" to "Default" to avoid ambiguity
+
+#### CI/CD
+- Removed `.claude/` config file validation step (.github/workflows/ci.yml:45)
+- Updated version test case from 5.1.0 → 5.2.0 (codeagent-wrapper/main_test.go:23)
+
+#### Commands & Documentation
+- Reverted `skills/codex/SKILL.md` to `codex-wrapper` for backward compatibility
+
+#### dev-workflow
+- Replaced Codex skill → codeagent skill throughout
+- Added UI auto-detection: backend tasks use codex, UI tasks use gemini
+- Corrected agent name: `develop-doc-generator` → `dev-plan-generator`
+
+### ⚙️ Configuration & Environment Variables
+
+#### New Environment Variables
+- `CODEAGENT_SKIP_PERMISSIONS`: Control permission check behavior
+  - Claude backend defaults to `--dangerously-skip-permissions` enabled, set to `true` to disable
+  - Codex/Gemini backends default to permission checks enabled, set to `true` to skip
+- `CODEAGENT_MAX_PARALLEL_WORKERS`: Parallel task concurrency limit (default: unlimited, recommended: 8, max: 100)
+
+#### Configuration Files
+- `config.schema.json`: Added `op_merge_json` schema validation
+
+### ⚠️ Breaking Changes
+
+**codex-wrapper → codeagent-wrapper rename**
+
+**Migration**:
+```bash
+python3 install.py --module dev --force
+```
+
+**Backward Compatibility**: `codex-wrapper/main.go` provides compatibility entry point
+
+### 📦 Installation
+
+```bash
+# Install dev module
+python3 install.py --module dev
+
+# List all modules
+python3 install.py --list-modules
+
+# Verbose logging mode
+python3 install.py --module dev --verbose
+```
+
+### 🧪 Test Results
+
+✅ **All tests passing**
+- Overall coverage: 93.4%
+- Security scan: 0 issues (gosec)
+- Linting: Pass
+
+### 📄 Related PRs & Issues

 **Why this separation?**
 - Claude Code excels at understanding context and orchestrating complex workflows
- Codex excels at focused code generation and execution
- Together they provide better results than either alone

 - Requirements: Break the ask into explicit requirements, unclear areas, and hidden assumptions.
- Scope mapping: Identify codebase regions, files, functions, or libraries likely involved. If unknown, perform targeted parallel searches NOW before planning. For complex codebases or deep call chains, delegate scope analysis to Codex skill.
- Dependencies: Identify relevant frameworks, APIs, config files, data formats, and versioning concerns. When dependencies involve complex framework internals or multi-layer interactions, delegate to Codex skill for analysis.

 - Output contract: Define exact deliverables (files changed, expected outputs, API responses, CLI behavior, tests passing, etc.).

cexll	f57ea2df59	chore: bump version to 5.2.4 Generated with swe-agent-bot Co-Authored-By: swe-agent-bot <agent@swe-agent.ai>	2025-12-16 10:17:47 +08:00
cexll	d215c33549	fix(executor): isolate log files per task in parallel mode Previously, all parallel tasks shared the same log file path, making it difficult to debug individual task execution. This change creates a separate log file for each task using the naming convention: codeagent-wrapper-{pid}-{taskName}.log Changes: - Add withTaskLogger/taskLoggerFromContext for per-task logger injection - Modify executeConcurrentWithContext to create independent Logger per task - Update printTaskStart to display task-specific log paths - Extract defaultRunCodexTaskFn for proper test hook reset - Add runCodexTaskFn reset to resetTestHooks() Test coverage: 93.7% Generated with swe-agent-bot Co-Authored-By: swe-agent-bot <agent@swe-agent.ai>	2025-12-16 10:05:54 +08:00

swe-agent[bot]	6f4f4e701b	fix(parser): 修复 bufio.Scanner token too long 错误 (#64 ) ## 问题 - 执行 rg 等命令时，如果匹配到 minified 文件，单行输出可能超过 10MB - 旧实现使用 bufio.Scanner，遇到超长行会报错并中止整个解析 - 导致后续的 agent_message 无法读取，任务失败 ## 修复 1. parser.go: - 移除 bufio.Scanner，改用 bufio.Reader + readLineWithLimit - 超长行（>10MB）会被跳过但继续处理后续事件 - 添加 codexHeader 轻量级解析，只在 agent_message 时完整解析 2. utils.go: - 修复 logWriter 内存膨胀问题 - 添加 writeLimited 方法限制缓冲区大小 3. 测试: - parser_token_too_long_test.go: 验证超长行处理 - log_writer_limit_test.go: 验证日志缓冲限制 ## 测试结果 - ✅ TestParseJSONStream_SkipsOverlongLineAndContinues - ✅ TestLogWriterWriteLimitsBuffer - ✅ 完整测试套件通过 Fixes #64 Generated with swe-agent-bot Co-Authored-By: swe-agent-bot <agent@swe-agent.ai>	2025-12-15 13:19:51 +08:00

swe-agent[bot]	edbf168b57	fix(codeagent-wrapper): fix race condition in stdout parsing 修复 GitHub Actions CI 中的测试失败问题。问题分析：在 TestRun_PipedTaskSuccess 测试中，当脚本运行很快时，cmd.Wait() 可能在 parseJSONStreamInternal goroutine 开始读取之前就返回，导致 stdout 管道被过早关闭，出现 "read \|0: file already closed" 错误。解决方案：将 parseJSONStreamInternal goroutine 的启动提前到 cmd.Start() 之前。这确保解析器在进程启动前就 ready，避免竞态条件。测试结果： - 本地所有测试通过 ✓ - 覆盖率保持 93.7% ✓ Generated with swe-agent-bot Co-Authored-By: swe-agent-bot <agent@swe-agent.ai>	2025-12-13 13:20:49 +08:00
