Data Directory

Workflow

Step 0: Check Prerequisites

Resolve the data directory, then check prerequisites per 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 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.

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
