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.mdandresume.mdfrom 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.mdandresume.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.mdif 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:
