Customizable Job Scanner
# Customizable Job Scanner - AI optimized
**Author:** Scott M
**Version:** 1.9 (see Changelog below)
**Goal:** Find 80%+ matching [job sector] roles posted within the specified window (default: last 14 days)
**Audience:** Job boards, company sites
**Supported AI:** Claude, ChatGPT, Perplexity, Grok, etc.

- **Version 1.9 (Current):**
- Added optional "If no matches, suggest adjustments" instruction at end.
- Added "Common Tags in Sector" fallback list for thin extraction.
- Made output table optionally sortable by Posted Date descending.
- In Resume Auto-Extract Mode: AI must report extracted key facts and any added tags before showing results.
## Resume Auto-Extract Mode (Optional - For Lazy/Fast Setup)
If you want to skip manually filling the Skills Reference section:
- Paste your full resume text (plain text, markdown, or key sections) here:
[PASTE RESUME TEXT HERE]
- Then add this instruction at the very top of your prompt when running:
"First, extract and summarize my skills, experience, achievements, and technical stack from the pasted resume text above. Populate the Skills Reference section automatically before proceeding with the job search. Report what you extracted and any tags you suggested/added."
The AI will:
- Pull professional overview, years/experience, major projects/quantifiable wins.
- Identify top skills (with proficiency levels if mentioned), tools/technologies.
- Build a technical stack list.
- Suggest or auto-map relevant tags for scoring.
- **Before showing job results**, output a summary like:
"Resume Extraction Summary:
- Experience: 30 years in IT/security at Aetna/CVS
- Key achievements: Led CrowdStrike migration (120K endpoints), BeyondTrust PAM for 2500 devs, 40% vuln reduction via Tanium
- Top skills mapped: Zero Trust (Expert), CrowdStrike (Expert), PowerShell (Expert), ...
- Added tags from resume/sector common: Splunk, SIEM, KQL
Proceeding with search using these."
Use this if you're short on time; manual editing is still better for precision.
## How to Update and Customize Effectively
To keep this prompt effective for different job sectors or as your skills evolve, follow these tips:
- **Use Resume Auto-Extract Mode** when you're feeling lazy: Paste resume → add the extraction instruction → run. The AI will report what it pulled/mapped so you can verify or tweak before results appear.
- **Update Skills Reference (Manual or Post-Extraction):** Replace placeholders or refine AI-extracted content. Be specific with quantifiable achievements to help matching. Refresh every 3-6 months or after big projects.
- **Customize Tags and Scoring:** List 15-25 key tags that represent your strongest, most unique skills. Prioritize core tags (2 points) for must-have expertise. Use the "Common Tags in Sector" fallback if extraction is thin.
- **Refine Job Parameters:**
- Set **Posting Window** to control freshness: "last 7 days" for daily checks, "last 14 days" (default), "last 30 days" when starting.
- Use **Minimum Salary Threshold** (e.g., "$130,000") to filter listed salaries. Set to "N/A" to disable.
- Add/remove companies based on your network or industry news.
- Customize location with your actual home base (e.g., East Hartford, CT), radius, and relocation prefs.
- **Test with AI Models:** Run in multiple AIs and compare. If too few matches, lower threshold or extend window.
- **Iterate Based on Results:** Note mismatches, tweak tags/weights. Review Posted Date/Salary columns and extraction summary (if used). Track changes in Changelog.
- **Best Practices:** Keep prompt concise. Use exact job-posting phrases in tags. For new sectors, research keywords via LinkedIn/Indeed. Provide clean resume text for best extraction.

### Posting Window
[Specify recency here, e.g., "14 days" (default), "7 days" for fresh-only, "30 days" when starting a search, or "since YYYY-MM-DD"]
### Minimum Salary Threshold
[Optional: e.g., "$130,000" or "$120K" to exclude lower listed salaries; set to "N/A" or blank to include all. Only filters jobs with explicit salary listed in posting.]
### Priority Companies (check career pages directly)
- [Company 1] ([career page URL]) # Choose companies relevant to the sector
- [Company 2] ([career page URL])
- [Add more as needed]
### Additional sources
LinkedIn, Indeed, ZipRecruiter, Glassdoor, Dice, Monster, SimplyHired, company career sites
### Job Types
Must include: [e.g., full-time, permanent]
Exclude: [e.g., part-time, internship, contract, temp, consulting, contractor, consultant, C2H]
### Location
Must match one of these work models:
- 100% remote

`[Tag1]`, `[Tag2]`, `[Tag3]`, etc.
Core/high-value skills worth 2 points: `[Core tag 1]`, `[Core tag 2]`, etc.
Everything else: 1 point
Calculate: matched points ÷ total possible points
Show only 80%+ matches
## Output format
Table with: Job Title | Match % | Company | Posted Date | Salary | URL
- **Posted Date:** Pull exact posted date if available (e.g., "2026-01-10" or "Posted Jan 10, 2026"). If approximate/not listed: "Approx. X days ago" or "N/A" — no guessing.
- **Salary:** Only show if explicitly listed (e.g., "$140,000 - $170,000"); "N/A" otherwise — no guessing/estimating/averages. If Minimum Salary Threshold set, exclude jobs below it.
- **Optional Sorting:** If there are matches, sort the table by Posted Date descending (most recent first) unless user specifies otherwise.
Remove duplicates (same title + company)
Put 90%+ matches in separate section at top called "Top Matches (90%+)"
If nothing found just say: "No strong matches found this week."
Then suggest adjustments, e.g.:
- "Try extending Posting Window to 30 days?"
- "Lower threshold to 75%?"
- "Add common sector tags like Splunk/SIEM if not already included?"
- "Broaden location to include more hybrid options?"
- "Check priority company career pages manually for unindexed roles?"
