- Strengthened Top Instruction block to enforce live searches and proper sequencing (extract first → then search).
## Top Instruction (Place this at the very beginning when you run the prompt)
"Act as my dedicated real-time job scout with current web browsing and search access.
First: [If using Resume Auto-Extract Mode: extract and summarize my skills, experience, achievements, and technical stack from the pasted resume text. Report the extraction summary including confidence levels (Expert/Strong/Inferred) before showing any job results.]
Then: Perform live, current searches only (no internal/training data or outdated knowledge). Pull the freshest postings matching my parameters below. Use the scoring system strictly. Prioritize ATS keyword alignment, recency, and my custom tags/skills."
## Resume Auto-Extract Mode (Optional - For Lazy/Fast Setup)
If skipping manual Skills Reference:
- Paste your full resume text here:
[PASTE RESUME TEXT HERE]
- Keep the Top Instruction above with the extraction part enabled.
The AI will output something like:
"Resume Extraction Summary:
- Experience: 12+ years in cybersecurity / DevOps / [sector]
- Key achievements: Led X migration (Y endpoints), reduced Z by A%
- Top skills (with confidence): CrowdStrike (Expert), Terraform (Strong), Python (Expert), ...
- Suggested tags added: SIEM, KQL, Kubernetes, CI/CD
Proceeding with search using these."
## How to Update and Customize Effectively
- Use Resume Auto-Extract when short on time; verify the summary before trusting results.
- Refresh Skills Reference / tags every 3–6 months or after major projects.
- Use exact phrases from job postings / your resume in tags for ATS alignment.
- Test across AIs; if too few results → lower threshold, extend window, add adjacent titles/tags.
- For new sectors: research top keywords via LinkedIn/Indeed/Google Jobs first.
## Skills Reference
(Replace manually or let AI auto-populate from resume)
**Professional Overview**
- [Years of experience, key roles/companies]
- [Major projects/achievements with numbers]
**Top Skills**
- [Skill] (Expert/Strong): [tools/technologies]
- ...
**Technical Stack**

## Scoring System
Match job descriptions against my tags from Skills Reference + Common Tags:
- Core/high-value tags: 2 points each
- Standard tags: 1 point each
Bonuses:
+1–2 pts for verbatim / near-exact keyword matches (strong ATS signal)
+1 pt for quantifiable alignment (e.g. “manage large environments” vs my “120K endpoints”)
+1 pt for very recent posting (<7 days)
Match % = (total matched points / max possible points) × 100
Show only jobs ≥80%
## Output Format
Table:
| Job Title | Match % | Company | Posted Date | Location Type | Salary | ATS Overlap | URL | Why Strong Match? |
- **Posted Date:** Exact if available (YYYY-MM-DD or "Posted Jan 10, 2026"); otherwise "Approx. X days ago" or N/A
- **Salary:** Only if explicitly listed; N/A otherwise (no estimates)
- **Location Type:** Remote / Hybrid / Onsite
- **ATS Overlap:** e.g. "9/14 top tags matched" or "Strong keyword overlap"
- **Why Strong Match?:** 2–3 bullet highlights (only for 85%+ matches)
Sort table by Posted Date descending (most recent first), then Match % descending.
Remove duplicates (same title + company).
Put 90%+ matches in a separate section at top called **Top Matches (90%+)** with bolded rows or clear highlighting.
If no strong matches:
"No strong matches found in the current window."
Then suggest adjustments:
- Extend Posting Window to 30 days?
- Lower threshold to 75%?
- Add common sector tags (e.g. Splunk, Kubernetes, Python)?
- Broaden location / include more hybrid options?
- Include adjacent role titles (e.g. Cloud Engineer, Systems Engineer)?
- Temporarily allow contract roles?
- Remove/lower Minimum Salary Threshold?
- Manually check priority company career pages for unindexed postings?
