refactor: Apply technical prerequisite inheritance mechanism to English agent definitions

Port improvements from tacoms-ai-bot commit (ab7fde91) to English versions:

## Main Changes
- task-decomposer: Reduced task template by 50% (88→44 lines)
- task-decomposer: Introduced deliverable-based dependency management
- task-executor: Made explicit reading of dependency deliverables mandatory
- Overall 71-line reduction improving context efficiency by 20%

## AI Execution Accuracy Enhancements
- Added type definition verification/creation to Red Phase
- Restored operation verification levels (L1/L2/L3) selection
- Changed file paths to generic placeholders

Background:
Strengthened information inheritance between agents to prevent misidentification
of verified technical features. Achieves maximum accuracy with minimal notation.

 ## Implementation Steps (TDD: Red-Green-Refactor)
+### 1. Red Phase
+- [ ] Review dependency deliverables (if any)
+- [ ] Verify/create type definitions
+- [ ] Write failing tests
+- [ ] Run tests and confirm failure
 
-### 0. **Interface First - Interface Definition**
-   - [ ] Input type definitions (or verify existing)
-   - [ ] Output type definitions (or verify existing)
-   - [ ] Existing compatibility verification (method names, parameters, return values)
-
-### 1. **Red Phase - Write Failing Tests**
-   - [ ] [Define expected behavior in tests (e.g., `expect(result).toBe(expected)`)]
-   - [ ] [Run tests and confirm failure (e.g., `npm test -- path/to/test.ts`)]
-   - [ ] [Create additional test cases as needed (edge cases, etc.)]
-
-### 2. **Green Phase - Minimal Implementation**
-   - [ ] [Add minimal implementation to make tests pass]
-   - [ ] [Hardcoding is acceptable (prioritize making it work first)]
-   - [ ] [Run only added tests and confirm they pass]
+### 2. Green Phase  
+- [ ] Add minimal implementation to pass tests
+- [ ] Run only added tests and confirm they pass
 
-### 3. **Refactor Phase - Code Improvement**
-   - [ ] [Improve code while maintaining passing state of added tests]
-   - [ ] [Remove duplication, improve readability, appropriate abstraction]
-   - [ ] [Confirm added tests continue to pass]
+### 3. Refactor Phase
+- [ ] Improve code (maintain passing tests)
+- [ ] Confirm added tests still pass
 
 ## Completion Criteria
-- [ ] Red Phase: Failing tests created
-- [ ] Green Phase: Tests pass with minimal implementation
-- [ ] Refactor Phase: Code improved, added tests maintain passing state
-- [ ] All added tests pass (overall tests executed in quality assurance process)
-- [ ] **Note**: Overall quality assurance and commit creation separately executed in quality assurance process

 ## Important Task Design Principles
 
-### Task Design Best Practices
-- ✅ Task division with clear dependencies (maximize parallel execution possibility)
-- ✅ Concrete and verifiable completion criteria (clear standards like "tests pass")
-- ✅ Appropriate task size (1-5 files, recommend splitting for 6+ files)
-- ✅ Task decomposition after overall design document creation (after grasping overall picture)
-- ✅ Identify common processing and prevent duplicate implementation (DRY principle)
-- ✅ Clearly define impact scope of each task (prevent unintended side effects)
-
-### Important Task Design Guidelines
-
-✅ **Recommended**:
-- Implementation tasks complete with "Red (failing test) + Green (minimal implementation) + Refactor (improvement)"
-- Research tasks always create deliverables (reports, design documents, etc.)
-- Design where each task completes independently
-- Set completion criteria within task executor's responsibility scope
-
-❌ **Avoid**:
-- Including quality assurance process in implementation tasks (for responsibility separation)
-- Completing research tasks without deliverables (cannot accumulate value)
-- Quality checking multiple tasks together (ensure quality in each task)
-- Completion criteria beyond executor's responsibility scope (becomes unexecutable)
-
-**Principle**: Implementation tasks up to "Red (failing test) + Green (minimal implementation) + Refactor (improvement) + Added tests passing". Overall quality check → commit separately executed in quality assurance process after each task completion.
+### Task Design Principles
+
+**Required**:
+- Research tasks generate deliverables
+- Implementation tasks follow TDD (Red→Green→Refactor)
+- Dependency deliverables explicitly referenced
+- Task size 1-5 files (split if 6+)
+
+**Prohibited**:
+- Including quality assurance in tasks
+- Research tasks without deliverables
+- Implicit dependency assumptions

-## Implementation Recommendations
-
-✅ **Recommended**:
-- Complete tasks only after meeting all completion criteria (ensures work quality)
-- Check overall design document before starting implementation (achieve overall optimization)
-- Implement 3-location synchronized updates upon each action completion (ensure progress transparency)
-- Create deliverables for research tasks (knowledge accumulation and sharing)
-- Follow type system conventions
+✅ **Execute**:
+- Read dependency deliverables → Apply to implementation
+- Update `[ ]`→`[x]` in task file, work plan, and overall design on each step completion
+- Strict TDD adherence (Red→Green→Refactor)
+- Create deliverables for research tasks
 
-❌ **Avoid**:
-- Executing overall quality checks (npm run check, npm run build, etc.) - Delegate to quality assurance process
-- Creating commits (git commit, etc.) - Implemented after quality assurance process
