## 🔴 Priority 1: Critical Issues (COMPLETED)
### 1.1 Bug in `check_setup_status` ✅ FIXED
**File**: `src/resumejson_mcp/mcp/setup/v1/tools.py`
```python
experience_file_exists = store.store.storage_paths.experience_file.exists()
```
**Problem**: Accessing `store.store` when `store` doesn't have a `store` attribute throws `'ExperienceStore' object has no attribute 'store'`.
**Fix**: Investigate `ExperienceStore` class and correct the attribute access.
**Status**: ⬜ Not Started
---
### 1.2 Missing Error Handling in Experience Operations
**Files**: All experience tools
**Problem**: Most tools catch `ValueError` for ID not found but don't handle file I/O errors gracefully.
**Fix**: Add consistent error handling wrapper:
```python
def safe_experience_operation(func):
"""Decorator for consistent error handling."""
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except FileNotFoundError:
return "❌ Experience file not found. Run initialize_experience() first."
except json.JSONDecodeError:
return "❌ Experience file is corrupted. Check file integrity."
except Exception as e:
return f"❌ Unexpected error: {str(e)}"
return wrapper
```
**Status**: ⬜ Not Started
---
## 🟠 Priority 2: High-Impact Improvements
### 2.1 Consolidate Tool Descriptions with Structured Metadata
**Problem**: Tool descriptions are verbose and embedded in code. Hard to maintain consistency.
**Improvement**: Create a tool metadata system:
```python
# mcp/tool_metadata.py
TOOL_METADATA = {
"add_work": {
"name": "add_work",
"category": "experience",
"description": "Add a new work position...",
"examples": [...],
"required_fields": [...],
"related_tools": ["add_bullet_to_work", "add_major_project_to_work"],
}
}
```
**Status**: ⬜ Not Started
---
### 2.2 Add `update_basics_field` for Granular Updates
**File**: `src/resumejson_mcp/mcp/experience/v1/basics/tools.py`
**Problem**: `set_basics` is a full replacement operation. User just wants to update their phone number? They need to provide everything.
**New Tool**:
```python
@tool(name="update_basics_field")
def update_basics_field(field: str, value: Any) -> str:
"""Update a single field in basics without replacing everything.
Fields: name, label, email, phone, url, summary, location, profiles
"""
```
**Status**: ⬜ Not Started
---
### 2.3 Add Search/Filter Tools for Experience Data
**Problem**: No way to search within experience data. For large experience stores, finding specific content is difficult.
**New Tools**:
```python
@tool(name="search_experience")
def search_experience(query: str, sections: list[str] = None) -> str:
"""Full-text search across work bullets, project summaries, skills.
Args:
query: Search term
sections: Optional filter - ["work", "skills", "projects", "education"]
"""
@tool(name="filter_work_by_tags")
def filter_work_by_tags(tags: list[str], match_all: bool = False) -> str:
"""Filter work positions by tags."""
```
**Status**: ⬜ Not Started
---
### 2.4 Add Bulk Operations for Work Bullets
**File**: `src/resumejson_mcp/mcp/experience/v1/work/tools.py`
**Problem**: Adding multiple bullets requires multiple tool calls.
**New Tool**:
```python
@tool(name="add_bullets_to_work")
def add_bullets_to_work(work_id: str, bullets: list[MCPBullet]) -> str:
"""Add multiple bullets to a work position at once."""
```
**Status**: ⬜ Not Started
---
### 2.5 Improve Pending Actions Integration
**File**: `src/resumejson_mcp/mcp/workflow/v1/tools.py`
**Problems**:
1. Pending actions aren't persisted across sessions
2. No way to add custom pending actions
3. Tracker state can get stale
**Improvements**:
```python
@tool(name="add_custom_todo")
def add_custom_todo(description: str, priority: str = "MEDIUM", target_id: str = None) -> str:
"""Add a custom pending action for tracking."""
@tool(name="get_pending_todos_for_work")
def get_pending_todos_for_work(work_id: str) -> str:
"""Get pending actions specific to a work position."""
```
Also: Persist pending actions to disk (in experience folder).
**Status**: ⬜ Not Started
---
## 🟡 Priority 3: Medium Improvements
### 3.1 Add Validation Tools
**New Tools**:
```python
@tool(name="validate_experience")
def validate_experience() -> str:
"""Validate entire experience.json for completeness and consistency.
Checks:
- All work positions have required fields
- No duplicate IDs
- Skills referenced in work exist in skills section
- Date format consistency
"""
@tool(name="validate_work_position")
def validate_work_position(work_id: str) -> str:
"""Deep validation of a single work position."""
```
**Status**: ⬜ Not Started
---
### 3.2 Add Experience Statistics Tool
**New Tool**:
```python
@tool(name="get_experience_stats")
def get_experience_stats() -> str:
"""Get statistics about the experience store.
Returns:
- Total positions, bullets, projects
- Date range covered
- Skills by category
- Average bullets per position
- Coverage gaps
"""
```
**Status**: ⬜ Not Started
---
### 3.3 Add History/Undo Capability
**Problem**: Accidental deletions or bad updates can't be undone.
**Improvement**: Simple backup before destructive operations:
```python
def backup_before_write(func):
"""Create .bak file before modifying experience.json"""
...
@tool(name="restore_from_backup")
def restore_from_backup() -> str:
"""Restore experience.json from most recent backup."""
```
**Status**: ⬜ Not Started
---
### 3.4 Add Import/Export Tools
**New Tools**:
```python
@tool(name="export_to_linkedin_json")
def export_to_linkedin_json() -> str:
"""Export experience in LinkedIn import format."""
@tool(name="import_from_linkedin")
def import_from_linkedin(linkedin_data: dict) -> str:
"""Import work experience from LinkedIn export."""
@tool(name="export_to_standard_json_resume")
def export_to_standard_json_resume() -> str:
"""Export to standard JSON Resume (without mcp-details)."""
```
**Status**: ⬜ Not Started
---
### 3.5 Improve Template Tools
**File**: `src/resumejson_mcp/mcp/templates/v1/tools.py`
**Improvements**:
```python
@tool(name="validate_template")
def validate_template(template_name: str) -> str:
"""Validate template syntax and required variables."""
@tool(name="preview_template_with_sample_data")
def preview_template_with_sample_data(template_name: str) -> str:
"""Render template with sample data to preview layout."""
```
**Status**: ✅ Completed (Phase 3-4)
---
## 🟢 Priority 4: Nice-to-Have Enhancements
### 4.1 Add Interactive Prompts
**File**: Add to `src/resumejson_mcp/mcp_server.py`
```python
@prompt(name="gather_work_experience")
def gather_work_experience_prompt() -> str:
"""Interactive prompt for gathering detailed work experience."""
@prompt(name="tailor_resume_for_job")
def tailor_resume_prompt(job_description: str) -> str:
"""Prompt to guide AI through resume tailoring process."""
```
**Status**: ✅ Completed (Phase 5)
---
### 4.2 Add Resume Comparison Tool
```python
@tool(name="compare_resumes")
def compare_resumes(application_id_1: str, application_id_2: str) -> str:
"""Compare two tailored resumes to show differences."""
```
**Status**: ✅ Completed (Phase 4)
---
### 4.3 Add Job Description Analysis Tool
```python
@tool(name="analyze_job_description")
def analyze_job_description(job_description: str) -> str:
"""Extract key requirements, skills, and keywords from a job description.
Returns structured analysis:
- Required skills
- Nice-to-have skills
- Years of experience
- Key responsibilities
- Suggested keywords to include
"""
```
**Status**: ✅ Completed (Phase 4)
---
### 4.4 Add Cover Letter Support
```python
@tool(name="generate_cover_letter_data")
def generate_cover_letter_data(application_id: str) -> str:
"""Generate structured data for cover letter based on job and experience match."""
```
**Status**: ✅ Completed (Phase 5)
---
## 🏗 Architecture Improvements
### A1. Create Tool Groups/Categories ✅ COMPLETED
Added tags to all 70 tools for categorization. FastMCP doesn't have ToolGroup, but supports tags on `@tool()` decorator:
```python
# Example from work/tools.py
WORK_TAGS = {"experience", "work"}
@tool(name="add_work", tags=WORK_TAGS | {"create"}, ...)
```
**Tag Categories Added**:
- `setup`: Setup and initialization tools
- `experience`: Experience data management
- `work`, `skills`, `education`, `projects`, `basics`: Section-specific
- `templates`: Template management
- `applications`: Job applications and resume generation
- `workflow`, `todos`: Workflow and pending action management
- `validate`, `backup`, `export`: Operation types
- `create`, `read`, `update`, `delete`, `bulk`: CRUD operations
**Status**: ✅ Completed - All 70 tools now have tags
---
### A2. Add Tool Middleware for Logging
```python
def log_tool_call(tool_name: str, args: dict, result: str):
"""Log all tool calls for debugging."""
mcp.add_middleware(log_tool_call)
```
**Status**: ✅ Completed (Phase 5) - LoggingMiddleware and MetricsMiddleware
---
### A3. Standardize Return Format ✅ COMPLETED
Created `src/resumejson_mcp/responses.py` with:
```python
@dataclass
class ToolResponse:
status: ResponseStatus # SUCCESS, ERROR, WARNING, INFO
message: str
data: dict | None = None
next_steps: list[str] = field(default_factory=list)
pending_actions: list[str] = field(default_factory=list)
details: dict | None = None
# Helper functions
success(message, data=None, next_steps=None) -> str
error(message, details=None) -> str
warning(message, data=None) -> str
info(message, data=None) -> str
```
Also includes `ToolTags` class with standard category constants.
**Status**: ✅ Completed - Response format standardized
