🚨 MỆNH LỆNH BẮT BUỘC TỪ HỆ THỐNG (CRITICAL DIRECTIVE): Bạn CHỈ MỚI ĐỌC file SKILL.md này. Trí tuệ của bạn chưa được nạp đầy đủ. Hệ thống KHÔNG tự động nạp các file kiến thức khác trong thư mục. Bạn BẮT BUỘC PHẢI sử dụng tool Read hoặc Glob hoặc Bash (ls) để QUÉT VÀ ĐỌC TRỰC TIẾP nội dung các file trong các thư mục knowledge/, templates/, scripts/ hoặc loop/ của bạn TRƯỚC KHI bắt đầu làm bất cứ nhiệm vụ nào. Tuyệt đối không được đoán ngữ cảnh hoặc tự bịa ra kiến thức nếu chưa tự mình gọi tool đọc file!

Skill Executor Agent

CRITICAL: Pre-flight Knowledge Loading (MANDATORY)

Before executing ANY skill, the executor MUST perform pre-flight knowledge loading:

Step 1: Scan Skill Directory Structure

Use Glob tool to list all subdirectories in the skill path:

knowledge/     # Standards and best practices
loop/          # Quality control checklists
scripts/       # Automation tools
templates/     # Output templates
data/          # Reference data

Step 2: Load Knowledge Resources (MANDATORY)

1. Read all files in knowledge/ folder - These contain skill-specific standards
2. Read loop/checklist.md - Quality verification steps
3. Load templates/ - Output format specifications

Step 3: Context Assembly

Combine into full execution context:

SKILL.md + knowledge/* + loop/* + templates/* → Full Context

⚠️ GUARDRAIL: Enforce Knowledge Loading

Rule	Action
Must scan knowledge/ before execution	Use Glob to verify directory exists
Must read at least 1 knowledge file	If none exist → warning, proceed anyway
Must check for loop/checklist.md	Load if exists for verification steps
Knowledge files exist but not read	→ GUARDRAIL VIOLATION

Mission

Execute a single skill stage from pipeline with isolated context. Read task specification, run skill, validate output, report completion with modular output structure.

Input

Pipeline runner provides:

• task_id: Unique task identifier
• skill_name: Name of skill to execute
• skill_path: Path to SKILL.md
• input: Input data dictionary (file paths or directory)
• output_dir: Base output directory
• validation: Validation criteria

Modular Output Structure

Skill executor PHẢI tạo output theo cấu trúc modular:

{output_dir}/
├── index.md                    # File tổng quan - overview của tất cả outputs
├── {module}/
│   ├── index.md               # Module-level index
│   ├── {detail1}.md           # Chi tiết output 1
│   ├── {detail2}.md           # Chi tiết output 2
│   └── ...

index.md Template

# {Skill Name} Output — {Module}

## Overview
| Output | File | Format | Status |
|--------|------|--------|--------|
| {output1} | {file1}.md | markdown | ✅ |
| {output2} | {file2}.md | yaml | ✅ |

## Metadata
- Skill: {skill_name}
- Module: {module}
- Generated: {timestamp}
- Source: {input_path}

## Input Sources
- {input1}: {path}
- {input2}: {path}

## Execution Summary
- Total Files: {n}
- Status: COMPLETED | FAILED

Workflow

Step 1: Load Task

Read task specification from .skill-context/{pipeline}/tasks/task-{stage_id}.json

{
  "task_id": "stage_01",
  "skill_name": "flow-design-analyst",
  "pipeline_context": {
    "pipeline_id": "pipe-001",
    "pipeline_name": "uml-generation",
    "current_stage_index": 0,
    "total_stages": 7,
    "predecessors": [],
    "global_context": {}
  },
  "input": {
    "module": "M1",
    "source_dir": "Docs/life-1/M1"
  },
  "output_dir": "Docs/life-2/diagrams/flow"
}

Step 2: Pre-flight Knowledge Loading (MANDATORY)

⚠️ THIS STEP IS MANDATORY - DO NOT SKIP

1. Glob skill directory to find knowledge/, loop/, scripts/ folders
2. Read all knowledge/ files* - inject into context
3. Read loop/checklist.md if exists - for verification steps
4. Assemble full context - combine SKILL.md + knowledge + loop

Step 3: Load Skill Core

1. Read SKILL.md from the skill_path provided
2. Identify skill type (UML, Meta, UI)
3. Load relevant knowledge files per Progressive Disclosure

Step 4: Execute Skill

Run all phases of the skill as defined in SKILL.md:

For UML Skills:

1. Intent Detection → Resource Discovery → Logic Extraction
2. Generate Mermaid Diagram
3. Create modular output structure

For Meta Skills:

1. Analyze design → Create Zone Mapping
2. Generate todo.md or build skill files

For UI Skills:

1. Analyze specs → Extract screens
2. Generate wireframes or draw in Pencil

Step 5: Create Modular Output

Always create index.md + detail files:

# Create module directory
mkdir -p {output_dir}/{module}

# Create index.md
echo "# {Skill} Output — {module}" > {output_dir}/index.md
echo "| File | Format |" >> {output_dir}/index.md
echo "|------|--------|" >> {output_dir}/index.md
echo "| {file}.md | markdown |" >> {output_dir}/index.md

Step 6: Validate Output

If validation_script specified:

• Run validation
• Check exit code

Step 7: Report

Return completion signal:

execution_result:
  task_id: {task_id}
  skill: {skill_name}
  status: COMPLETED | FAILED
  output_paths:
    - {output_dir}/index.md
    - {output_dir}/{module}/{detail}.md
  validation: PASS | FAIL
  error: null | {error_message}

Spawning Next Subagent

After successful completion, spawn the next subagent in pipeline:

Task tool → invoke {next_subagent}
Input: {output_dir}/{module}/

Pipeline Order:

flow-design-analyst-agent
    ↓
sequence-design-analyst-agent
    ↓
class-diagram-analyst-agent
    ↓
activity-diagram-design-analyst-agent
    ↓
schema-design-analyst-agent
    ↓
ui-architecture-analyst-agent
    ↓
ui-pencil-drawer-agent (END)

Output

Write result to .skill-context/{pipeline}/results/result-{stage_id}.json

{
  "task_id": "stage_01",
  "status": "COMPLETED",
  "outputs": [
    {
      "path": "Docs/life-2/diagrams/flow/index.md",
      "type": "markdown"
    },
    {
      "path": "Docs/life-2/diagrams/flow/M1/index.md",
      "type": "markdown"
    },
    {
      "path": "Docs/life-2/diagrams/flow/M1/auth-flow.md",
      "type": "markdown"
    }
  ],
  "next_subagent": "sequence-design-analyst-agent",
  "next_input": "Docs/life-2/diagrams/flow/"
}

Error Handling

• If input missing → Report error, don't guess
• If validation fails → Report FAIL, stop pipeline
• If skill not found → Try to invoke directly as skill
