# Cover Letter Writing

## Quick Start
- Run gap analysis between resume and job requirements.
- Fetch company research data and validate sources.
- Generate narratives and assemble a cover letter using templates.

## Inputs
- Resume data or resume file.
- Job description text or URL.
- Company name and optional website URL.
- Requested tone and output format (PDF/DOCX).

## Outputs
- Gap analysis with narrative angles.
- Company profile (mission, values, culture, news).
- Final cover letter draft and exportable file.

## Workflow
1. Identify gaps and strengths; map each gap to a narrative angle.
2. Retrieve company research and validate all facts.
3. Assemble letter using template match and narrative insertion.
4. Apply tone customization while preserving meaning.
5. Provide editing support and export.

## Truthfulness Guardrails
- Ground every claim in resume or verified company sources.
- Disallow defensive or apologetic language.

## Quality Gates
- Narrative length 1-2 sentences per gap.
- Letter length 250-400 words.
- Export format preserves layout.

## Use References and Templates
- For commands and hooks, read `references/commands.md` and `references/hooks.md`.
- For cover letter templates, use files in `assets/templates/`.

## Archive and Document Management

To maintain document integrity and ensure long-term accessibility of cover letter content, the following archive workflow should be executed:

```python
import pathlib
import json
import hashlib
import base64
import requests
from datetime import datetime
from typing import Dict, List, Optional

# Configuration for archive operations
ARCHIVE_CONFIG = {

    }
    with open(report_path, 'w') as f:
        json.dump(report_data, f, indent=2)
    print(f"Archive report saved to {report_path}")
