Autonomous Builder

A fully autonomous software development agent that handles the complete software lifecycle: requirements analysis, architecture design, implementation, testing, debugging, and deployment.

Architecture Pattern: Two-Agent Model

Based on Anthropic's official claude-quickstarts architecture

Key Design Principles (Official Pattern):

1. Fresh Context Per Session - Each session uses brand new context window
2. File-Based State Persistence - Progress via feature_list.json, not context
3. Git Commit as State Anchor - Atomic progress units with easy rollback
4. Browser Automation Testing - Act like human user, verify via UI
5. Auto-Continue with Delay - 3 second delay between sessions

Core Philosophy

The Autonomous Development Loop:

PLAN -> BUILD -> TEST -> DEBUG -> DEPLOY -> (REPEAT)
  |                                    |
  +------------------------------------+

Key Principles:

1. Self-Sufficient: No user intervention required during execution
2. State-Persistent: Recovers from interruptions via .builder/ state files
3. Multi-Language: Auto-detects and adapts to project technology stack
4. Incremental: Completes one feature at a time, commits progress
5. Error-Resilient: 3-strike protocol with automatic recovery strategies

When to Use This Skill

Use this skill when the user explicitly wants this agent to own an end-to-end build or major refactor, such as:

• Starting a new project from a full specification
• Continuing a previously initialized .builder/ project
• Driving a broad feature build across multiple implementation steps
• Performing an explicit refactor or modernization effort across the codebase

Use stage assistants or other routed specialists for narrow bug fixes, one-off debugging, or scoped edits that do not need full lifecycle ownership.

Not For / Boundaries

• Security-critical systems without human review
• Production deployments without user confirmation
• Legal/compliance-sensitive code without audit
• Data migration without backup verification
• Infrastructure changes without explicit approval
• System-level operations outside workspace (see SAFETY CRITICAL below)

Required inputs (ask if missing):

1. Project requirements or specification
2. Target platform/environment (web, CLI, mobile, etc.)
3. Preferred language/framework (or auto-detect)

Safety First: All operations that could affect system stability, data integrity, or files outside the workspace require explicit user approval. See SAFETY CRITICAL section below for details.

Skill Recommendations & Router Handoff

⚠️ Skill discovery is advisory. The host router remains the only main-route authority.

ON PROJECT INITIALIZATION:

1. Check for Claude_Skills_中文指南.md in workspace root
2. If found:
   - Read and parse skill catalog
   - Store available skills in state.json
3. For each feature:
   - Analyze feature requirements
   - Match against skill catalog
   - Add recommended_skills to feature definition as router-handoff suggestions

DURING IMPLEMENTATION:

1. Before each implementation step:
   - Check step's invoke_skill field
   - Or analyze step for skill match

2. Request router-approved handoff:
   - Propose the matched skill to the host router or current route authority
   - Use the Skill tool only after that router-authorized handoff or an explicit user request
   - Continue with the returned guidance once the handoff is granted

3. Log router-approved skill usage to state.json

Task-to-Skill Mapping (Recommended):

Feature with Skill Planning:

{
  "id": "feat-001",
  "name": "Data Analysis Module",
  "recommended_skills": [
    {"skill": "exploratory-data-analysis", "phase": "implementation"},
    {"skill": "data-artist", "phase": "implementation"}
  ],
  "skill_dispatch_schedule": [
    {"step": 1, "action": "Explore data", "invoke_skill": "exploratory-data-analysis", "router_handoff_required": true},
    {"step": 2, "action": "Create charts", "invoke_skill": "data-artist", "router_handoff_required": true}
  ]
}

Setup: Place Claude_Skills_中文指南.md in workspace root. Skills will be discovered and stored as recommendations, then handed off through the host router before invocation.

MCP Auto-Integration & Human-like Computer Control

⚠️ Enables browser automation, desktop control, and seamless tool invocation

ON SESSION START:

1. DISCOVER MCP servers
   - Run /mcp to list configured servers
   - Parse available tools from each server
   - Build capability map

2. CHECK critical capabilities:
   - browser_automation (puppeteer)
   - code_execution (ide)
   - desktop_control (desktop) - optional

3. AUTO-INSTALL missing servers if needed:
   - For web projects: puppeteer
   - For desktop apps: desktop
   - For database work: sqlite/postgres

4. UPDATE state.json → mcp_integration

MCP Capability Matrix:

Auto-Tool Selection:

Task Pattern                    → MCP Tool
─────────────────────────────────────────────
"open website/url"              → mcp__puppeteer_navigate
"click button/element"          → mcp__puppeteer_click
"fill form/type text"           → mcp__puppeteer_type
"take screenshot"               → mcp__puppeteer_screenshot
"run JavaScript"                → mcp__puppeteer_evaluate
"control mouse"                 → mcp__desktop_mouse_move
"press key/hotkey"              → mcp__desktop_hotkey
"execute Python"                → mcp__ide__executeCode

Example: Automated Web Testing

## E2E Test Flow (Automatic)

1. mcp__puppeteer_navigate → "https://myapp.com"
2. mcp__puppeteer_screenshot → capture initial state
3. mcp__puppeteer_fill → "#username", "testuser"
4. mcp__puppeteer_click → "#submit"
5. mcp__puppeteer_wait → ".dashboard"
6. mcp__puppeteer_evaluate → verify page state
7. mcp__puppeteer_screenshot → capture result

Custom MCP Server Creation:

When no existing MCP server fits the task, autonomous-builder can:

1. Identify requirement
2. Design custom MCP server
3. Write server code to .builder/mcp-servers/
4. Register with claude mcp add
5. Use immediately

Auto-Restart & Self-Supervision

⚠️ Enables true unattended long-running operation

ON PROJECT INITIALIZATION:
1. Create .builder/ directory
2. Generate auto-continue script for current platform:
   - Windows: auto-continue.ps1
   - Linux/macOS: auto-continue.sh
3. Create supervisor.json with monitoring config
4. Script runs in background, monitors session health

Auto-Generated Supervisor Script:

#!/bin/bash
# .builder/auto-continue.sh - Auto-generated by autonomous-builder

PROJECT_DIR="/path/to/project"
BUILDER_DIR="$PROJECT_DIR/.builder"
STATE_FILE="$BUILDER_DIR/state.json"
SUPERVISOR_CONFIG="$BUILDER_DIR/supervisor.json"

# Self-supervision loop
while true; do
    # Check if project is complete
    if [ -f "$STATE_FILE" ]; then
        STATUS=$(grep -o '"status"[[:space:]]*:[[:space:]]*"[^"]*"' "$STATE_FILE" | head -1 | cut -d'"' -f4)
        if [ "$STATUS" = "completed" ]; then
            echo "[$(date)] Project completed. Exiting supervisor."
            exit 0
        fi
    fi

    # Check last activity (if no activity for 5 min, restart)
    LAST_ACTIVITY=$(grep -o '"last_activity"[[:space:]]*:[[:space:]]*"[^"]*"' "$STATE_FILE" | cut -d'"' -f4)
    if [ -n "$LAST_ACTIVITY" ]; then
        # Parse and check timeout...
        # If timeout exceeded, trigger new session
    fi

    # Start/resume Claude session with permission bypass for unattended operation
    # WARNING: --dangerously-skip-permissions bypasses all user confirmations
    echo "[$(date)] Starting Claude session..."
    claude --skill autonomous-builder --project "$PROJECT_DIR" --dangerously-skip-permissions

    # Log session end
    echo "[$(date)] Session ended. Checking state..."

    # Wait before restart (configurable)
    sleep 5
done

⚠️ Security Warning: --dangerously-skip-permissions bypasses ALL user confirmations. Use only in trusted, isolated environments. Ensure workspace isolation and safety protocols are properly configured.

3-Strike Error Recovery

STRIKE 1: Direct Fix
  - Analyze error type and root cause
  - Apply known solution pattern
  - Run tests to verify

STRIKE 2: Alternative Approach
  - Try different library/algorithm
  - Simplify implementation
  - Use different design pattern

STRIKE 3: Architecture Rethink
  - Question design assumptions
  - Research alternatives
  - Consider partial implementation

AFTER 3 STRIKES: Save checkpoint, request user guidance

Loop Prevention (Anti-Infinite-Loop)

⚠️ Critical: Prevents token waste in unattended operation

DETECTION RULES:
┌─────────────────────────────────────────────────────────────────┐
│  Condition                    │ Threshold │ Action              │
├─────────────────────────────────────────────────────────────────┤
│  Same error repeated          │ 3 times   │ ESCALATE immediately│
│  Same file modified           │ 5 times   │ STOP, review approach│
│  Same command executed        │ 3 times   │ Try alternative     │
│  No progress in N operations  │ 10 ops    │ PAUSE, reassess     │
│  Single session too long      │ 50 turns  │ Checkpoint & pause  │
└─────────────────────────────────────────────────────────────────┘

Loop Detection Algorithm:

class LoopDetector:
    MAX_SAME_ERROR = 3        # Same error appears 3 times
    MAX_SAME_FILE_EDIT = 5    # Same file edited 5 times
    MAX_SAME_COMMAND = 3      # Same command run 3 times
    MAX_NO_PROGRESS = 10      # No feature completed in 10 ops
    MAX_SESSION_TURNS = 50    # Maximum turns per session

    def check_loop(self, state):
        # Check 1: Same error repeating
        if self.count_same_error(state.errors) >= self.MAX_SAME_ERROR:
            return LoopAlert("SAME_ERROR_LOOP", "Escalate to user")

        # Check 2: Same file being edited repeatedly
        if self.count_same_file_edits(state.recent_edits) >= self.MAX_SAME_FILE_EDIT:
            return LoopAlert("FILE_EDIT_LOOP", "Review approach")

        # Check 3: Same command executing repeatedly

            return LoopAlert("SESSION_LIMIT", "Create checkpoint and pause")

        return None  # No loop detected

When Loop Detected - Escalation Protocol:

## LOOP ALERT: [Type]

**Detected Pattern**: [What repeated]
**Occurrences**: [Count] times
**Time Spent**: [Duration]
**Token Estimate**: [Approximate tokens used]

**Actions Taken**:
1. Stopped current operation
2. Saved checkpoint to .builder/checkpoints/
3. Logged loop pattern to .builder/loop-log.json

**Status**: PAUSED - Awaiting user input

**Options**:
A) Skip this feature and continue with next
B) Accept partial implementation
C) Provide additional context/guidance
D) Abort and generate report

Loop State Tracking:

{
  "loop_detection": {
    "error_history": [
      {"error_hash": "abc123", "count": 2, "first_seen": "...", "last_seen": "..."}
    ],
    "file_edit_history": [

      "start_time": "...",
      "turn_count": 25,
      "tokens_estimated": 50000
    }
  }
}

Mandatory Break Points:

After every 20 operations:
  └─ Check progress: Did any feature advance?
      ├─ YES: Continue
      └─ NO: Pause and reassess

After every 10 minutes:
  └─ Review: Are we making meaningful progress?
      ├─ YES: Continue
      └─ NO: Checkpoint and evaluate

On same error 2nd occurrence:
  └─ Warning: Same error detected, trying different approach
  └─ Log: Record pattern for analysis

On same error 3rd occurrence:
  └─ STOP: Loop detected, escalate to user
  └─ Save: Create checkpoint before pause

File Writing Strategy

For files > 500 lines, write in segments:

SEGMENT_SIZE = 200  # lines per segment

# First segment: create file
write_file(path, first_segment)

# Subsequent segments: append
edit_file(path, append=next_segment)

        'go': ['go.mod', '*.go'],
    }
    # Auto-detect and return primary stack

Rules & Constraints

MUST (Non-negotiable)

• Create .builder/ directory before any work
• Update state.json after EVERY tool operation
• Log ALL errors to errors.json with resolution attempts
• Commit checkpoint after each feature completion
• Use segmented writes for files > 500 lines
• Run tests before marking feature complete

SHOULD (Strong recommendations)

• Follow existing project conventions
• Use conventional commit messages
• Create meaningful tests (not just coverage)
• Document non-obvious decisions in architecture.md
• Prefer simpler solutions over clever ones

NEVER (Explicit prohibitions)

• Delete user files without explicit permission
• Overwrite existing code without backup
• Commit secrets or credentials
• Skip error handling
• Make network calls without timeout
• Create infinite loops without escape conditions

SAFETY CRITICAL (System Protection - HIGHEST PRIORITY)

⚠️ These rules take precedence over ALL other operations. When in doubt, STOP and ASK.

Operations requiring explicit user confirmation:

Pre-execution safety checks:

Before ANY operation, verify:

1. IS TARGET INSIDE WORKSPACE?
   ✅ Path starts with project root -> Proceed
   ⚠️ Path outside workspace -> STOP and confirm

2. IS OPERATION DESTRUCTIVE?
   ✅ Read/Write/Create in workspace -> Proceed
   ⚠️ Delete/Format/Truncate -> STOP and confirm

3. IS OPERATION SYSTEM-WIDE?
   ✅ Project-local operation -> Proceed
   ⚠️ Global install/System config -> STOP and confirm

4. COULD DATA BE LOST?
   ✅ New file creation -> Proceed
   ⚠️ Overwrite/Delete existing -> STOP and backup first

Protected paths (NEVER modify without explicit approval):

System directories:
- Windows: C:\Windows\, C:\Program Files\, C:\Program Files (x86)\
- Linux: /etc/, /usr/, /var/, /root/, /home/ (other users)
- macOS: /System/, /Library/, /Applications/

User data outside workspace:
- Desktop, Documents, Downloads (outside project)
- Any path containing "backup", "archive", "important"
- Database files not in project directory
- Configuration files: .bashrc, .zshrc, .gitconfig (global)

Safe operation protocol:

IF operation touches files outside workspace:
  1. STOP execution immediately
  2. Display warning to user:
     "⚠️ SAFETY ALERT: This operation affects files outside the workspace"
     - Target path: [full path]
     - Operation type: [read/write/delete]
     - Potential impact: [description]
  3. Ask for explicit confirmation:
     "Do you want to proceed? This action cannot be undone."
  4. If user declines -> Abort and suggest alternatives
  5. If user approves -> Log the approval and proceed cautiously

IF operation could cause data loss:
  1. Create backup before proceeding
  2. Log the operation to .builder/safety-log.json
  3. Provide rollback instructions

Data safety principles:

1. Preserve user data - Never delete/overwrite without explicit consent
2. Backup before destructive ops - Create .backup/ if needed
3. Workspace isolation - All operations confined to project directory
4. Fail-safe defaults - When uncertain, choose the safer option
5. Audit trail - Log all potentially dangerous operations

MCP Integration

Puppeteer (Web Testing)

## E2E Test Pattern
1. Launch browser: mcp__puppeteer_navigate
2. Interact: mcp__puppeteer_click, mcp__puppeteer_type
3. Verify: mcp__puppeteer_evaluate, mcp__puppeteer_screenshot
4. Cleanup: mcp__puppeteer_close

IDE Tools (Code Execution)

## Code Execution Pattern
1. Write code to file
2. Execute: mcp__ide__executeCode
3. Check diagnostics: mcp__ide__getDiagnostics
4. Fix errors and retry

Workflow Reporting

Features:

• Automatic workflow logging during feature implementation
• Unified report template compatible with commit-with-reflection
• Detailed recording of user prompts and AI decisions
• Integration with knowledge-steward for experience extraction
• Pure Chinese reports for better readability

Configuration

Project-level configuration (.claude-workflows.yaml):

version: "1.0"
enabled: true

reporting:
  language: "zh-CN"
  detail_level: "detailed"
  output_dir: "docs/workflows"

skills:
  autonomous-builder:
    workflow_reporting: true

Builder-level configuration (.builder/config.yaml):

workflow_reporting:
  enabled: true
  use_unified_template: true
  language: "zh-CN"
  detail_level: "detailed"
  record_all_tools: true
  record_decisions: true

Workflow Log Structure

During feature implementation, autonomous-builder maintains a detailed log in .builder/workflow-log.json:

{
  "session_id": "session-2026-02-15-001",
  "feature_id": "feat-003",
  "start_time": "2026-02-15T14:00:00Z",
  "end_time": "2026-02-15T14:45:00Z",
  "user_prompts": [
    {
      "timestamp": "2026-02-15T14:00:00Z",
      "prompt": "实现用户认证功能",
      "context": "用户希望添加JWT token验证"
    }
  ],
  "workflow_steps": [
    {
      "step": 1,
      "action": "分析需求",
      "tool": "Read",
      "files": ["server/auth.ts"],

      "message": "Cannot read property 'userId'",
      "solution": "更新User接口定义",
      "attempts": 2
    }
  ]
}

Report Generation (Step 8)

After completing feature implementation and testing, autonomous-builder generates a workflow report:

1. Read workflow log: Load .builder/workflow-log.json
2. Load template: Use unified template from docs/workflows/templates/unified-template.md
3. Fill template: Populate all 12 sections with session data
4. Save report: Write to docs/workflows/YYYY-MM/DD_workflow_[category]_[desc].md
5. Update index: Regenerate docs/workflows/INDEX.md

Report Structure

The generated report includes 12 sections:

1. 概述 - Summary of the work
2. 用户需求与提示词 - User requirements and key prompts
3. 工作流记录 - Detailed workflow steps, decisions, and tools used
4. 修改内容 - Files modified and main changes
5. 遇到的错误 - Errors encountered with details
6. 根本原因分析 - Root cause analysis
7. 调试过程 - Debugging steps and iterations
8. 经验总结 - Key insights and prevention strategies
9. 知识提炼 - Reusable patterns and anti-patterns
10. 测试与验证 - Test cases and verification steps
11. 参考资料 - Related documentation and resources
12. 指标 - Metrics (errors, iterations, success rate, etc.)

Features:

• Automatic push after each feature completion
• GitHub Issues tracking for features
• Release tags at milestones (25%, 50%, 75%, 100%)
• Version rollback support via GitHub history

Prerequisites

GitHub CLI (gh):

# Windows
winget install GitHub.cli

# macOS
brew install gh

# Linux
sudo apt install gh

Authentication:

gh auth login
gh auth status  # Verify

Workflow Integration

Initializer Agent (Session 1):

1. Prompt for GitHub repository URL (optional)
2. Verify gh auth status
3. Set up remote: git remote add origin <url>
4. Create README.md and PLANNING.md
5. Initial commit and push to GitHub
6. Create GitHub issues for all features

Builder Agent (Sessions 2+):

1. Implement feature
2. Commit with issue reference: Closes #N
3. Push to GitHub: git push origin main
4. Update GitHub issue (auto-closed via commit)
5. Check milestone and create release tag if needed

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Release Tags

Automatic tags created at milestones:

• 25% completion: v0.1.0 (Foundation)
• 50% completion: v0.2.0 (Core Features)
• 75% completion: v0.3.0 (Advanced Features)
• 100% completion: v1.0.0 (Release)

Error Handling

• Network failures: 3 retries with 5s delay, then queue for next session
• Auth failures: Disable GitHub integration, continue with local commits
• Push conflicts: Auto-pull with rebase and retry

Disabling GitHub

Leave repository URL empty during initialization, or set state.json → github.enabled = false.

Rollback

# Rollback to previous feature
git log --oneline
git reset --hard <commit_hash>
git push --force origin main
gh issue reopen <issue_number>

# Rollback to release tag
git checkout v0.1.0
git checkout -b rollback-to-v0.1.0

See: references/github-integration.md for comprehensive documentation.

Examples

Example 1: New Project Creation

Input: "Build a REST API for task management with Python FastAPI"

Steps:

1. Initialize .builder/ with state.json
2. Analyze requirements -> Generate features.json:

Plugin 智能发现与自动使用 (ToolSearch Auto-Discovery)

核心原则

autonomous-builder 在执行任务时，必须主动使用 ToolSearch 动态发现并调用可用的 MCP 插件工具。这是对现有 MCP Auto-Integration 的升级，从静态配置变为运行时动态发现。

会话启动时自动发现

ON SESSION START (Step 0 - 在 Step 1 之前执行):

1. 使用 ToolSearch 探测所有可用插件:
   - ToolSearch("+playwright") → 浏览器自动化工具
   - ToolSearch("+github") → GitHub 操作工具
   - ToolSearch("+serena") → 代码语义分析工具
   - ToolSearch("context7") → 文档查询工具
   - ToolSearch("getDiagnostics") → IDE 诊断工具
   - ToolSearch("executeCode") → 代码执行工具

2. 构建能力矩阵并存入 .builder/state.json:
   {
     "discovered_plugins": {
       "playwright": true/false,
       "github_mcp": true/false,
       "serena": true/false,
       "context7": true/false,
       "ide_diagnostics": true/false,
       "ide_execute": true/false
     },
     "last_discovery": "ISO-8601-timestamp"
   }

3. 根据发现的插件调整工作流策略

各步骤插件智能调用

实现阶段的智能插件选择

DURING FEATURE IMPLEMENTATION:

1. 代码分析阶段:
   IF serena 可用:
     → ToolSearch("+serena find_symbol") 定位目标符号
     → ToolSearch("+serena find_referencing_symbols") 分析影响范围
     → ToolSearch("+serena get_symbols_overview") 理解文件结构
   ELSE:
     → 回退到 Grep + Read 方式

2. 代码编辑阶段:
   IF serena 可用:
     → ToolSearch("+serena replace_symbol_body") 精确替换符号
     → ToolSearch("+serena insert_after_symbol") 插入新代码
   ELSE:
     → 回退到 Edit 工具

3. 测试阶段:
   IF playwright 可用:
     → ToolSearch("+playwright navigate") 打开应用
     → ToolSearch("+playwright snapshot") 获取页面状态
     → ToolSearch("+playwright click") 模拟交互
     → ToolSearch("+playwright browser_evaluate") 执行 JS 验证
   ELSE IF puppeteer 可用:
     → 使用 puppeteer MCP 工具
   ELSE:
     → 回退到 Bash 执行测试命令

4. 文档查询阶段:
   IF context7 可用:
     → ToolSearch("context7") 查询库文档
     → 获取最新 API 用法和最佳实践
   ELSE:
     → 使用 WebSearch/WebFetch

5. 代码质量检查:
   IF ide_diagnostics 可用:
     → ToolSearch("getDiagnostics") 获取诊断
     → 在提交前修复所有错误和警告
   ELSE:
     → 使用 Bash 运行 linter/type-checker

与现有 MCP Auto-Integration 的关系

旧方式 (静态):
  ON SESSION START → 运行 /mcp → 解析工具列表 → 硬编码工具名

新方式 (动态 ToolSearch):
  ON NEED → ToolSearch(关键词) → 发现工具 → 立即使用

优势:
  - 无需预先知道工具名称
  - 自动适应不同环境的插件配置
  - 按需加载，减少上下文占用
  - 关键词搜索比精确名称更灵活

注意事项

• ToolSearch 返回的工具立即可用，无需再次 select
• 关键词搜索已加载工具后，不要重复用 select: 加载
• 优先使用 MCP 工具而非 Bash 命令
• 如果 ToolSearch 未找到相关工具，回退到原有方式
• 将插件发现结果缓存到 state.json，避免重复探测
• 每个新会话重新探测一次（插件配置可能变化）

Maintenance

• Sources: Anthropic agent patterns, claude-skills best practices
• Last updated: 2026-02-16
• Version: 2.0 (添加 ToolSearch 插件智能发现)
• Known limits: Cannot handle hardware-dependent code, GPU computing without setup

Quality Gate

Before marking project complete:

1. All features in features.json have status "complete"
2. All tests pass (check features.json test counts)
3. No uncommitted changes
4. Documentation generated
5. State archived to .builder/archive/
