Priority hierarchy: See shared/references/priority-hierarchy.md for conflict resolution.

Write natural, persuasive cover letters that sound like a real professional wrote them.

Quick Start

• /proficiently:cover-letter - Start the flow (will ask for a job URL)
• /proficiently:cover-letter https://... - Write a cover letter for a specific job posting
• /proficiently:cover-letter last - Write a cover letter for the most recent job

File Structure

scripts/
  write-cover-letter.md       # Cover letter writing agent prompt

Data Directory

Resolve the data directory using shared/references/data-directory.md.

Workflow

Step 0: Check Prerequisites

Resolve the data directory, then check prerequisites per shared/references/prerequisites.md. Resume is required; profile is recommended but not blocking.

Step 1: Get Job Details

If `$ARGUMENTS` is "last" or empty:

• Check DATA_DIR/jobs/ for the most recently modified folder
• If found, read posting.md and resume.md from that folder
• Confirm with the user which job this is for
• If no job folders exist, ask the user for a job URL

If `$ARGUMENTS` is a URL:

• Check if a job folder already exists for this company in DATA_DIR/jobs/
• If yes, read the existing posting.md and resume.md
• If no, use Claude in Chrome MCP tools to fetch the job posting per shared/references/browser-setup.md
• Save the posting to DATA_DIR/jobs/[company-slug]-[date]/posting.md if not already saved

If the page can't be loaded, ask the user to paste the job description directly.

Step 2: Gather Materials

For the target job folder, check what exists:

• posting.md - the job description (required)
• resume.md - a tailored resume (optional, improves quality significantly)

If no tailored resume exists, use the original resume and work history profile directly.

Step 3: Write the Cover Letter

Follow the framework in scripts/write-cover-letter.md. Use:

• The work history profile (or original resume if no profile)
• The tailored resume for this role (if available)
• The job posting

The cover letter must:

• Be 250-350 words
• Start with "Dear Hiring Manager,"
• End with "Regards, [Name]"
• Use ONLY hyphens, never em dashes
• Sound like a real human wrote it
• Never fabricate or exaggerate any detail
• Connect 2-3 specific, measurable achievements to the employer's needs

Step 4: Present and Save

Save to DATA_DIR/jobs/[company-slug]-[date]/cover-letter.md

Present the cover letter to the user with:

• The full text
• A brief note on which achievements were highlighted and why
• The file path where it's saved

Step 5: Iterate

Ask if the user wants to adjust:

• Tone (more formal, more casual, more technical)
• Which achievements to highlight
• Specific phrasing
• Length

Apply changes and re-save.

After the user is satisfied with the cover letter, include:

Response Format

Structure user-facing output with these sections:

1. Cover Letter — the full cover letter text
2. Writing Notes — which achievements were highlighted and why, any tradeoffs made
3. What's Next — suggest iterating on tone/emphasis, or using other skills
