Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ats-resume-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ATS Resume Checker

Trigger

Use when the user wants to check, fix, optimize, or review their resume for ATS compatibility — including formatting issues, weak bullets, missing metrics, or keyword gaps.

Keywords: "check resume", "ats check", "ats resume checker", "ats score", "ats scan", "resume scanner", "is my resume ats friendly", "optimize resume", "improve resume", "fix my resume", "resume not getting interviews", "resume not working", "add metrics to resume", "format resume", "resume score", "applicant tracking system", "resume keywords", "resume bullet points", "one-page resume"

Process

Step 1: Assess

Scan for issues in priority order:

  1. ATS blockers — tables, columns, text boxes, images, headers/footers with contact info, non-standard fonts, embedded graphics
  2. Weak bullets — passive language ("responsible for", "helped with"), missing metrics, duties instead of achievements
  3. Keyword gaps — if a job description is provided, check for missing required terms
  4. Formatting — inconsistent dates, mixed fonts/sizes, poor hierarchy, wrong length
  5. Section issues — missing summary, missing skills section, non-standard headers

Step 2: Fix ATS Issues

  • Single-column layout only
  • Standard headers: "Professional Experience", "Education", "Skills", "Summary"
  • Contact info in document body, never in headers/footers
  • Standard fonts (Arial, Calibri, Georgia, Times New Roman), 10-12pt body
  • Simple bullet characters (-, *)
  • Consistent date format (Mon YYYY)
  • File naming: FirstName_LastName_Resume.pdf

Step 3: Rewrite Bullets

Every bullet follows: [Action Verb] + [What You Did] + [Measured Result] + [Scale/Context]

  • Start with a strong verb (Led, Built, Grew, Reduced, Launched — never "Responsible for" or "Helped with")
  • Every bullet needs at least one number
  • 1-2 lines max per bullet
  • Show achievements, not duties

When the user says "I don't have numbers" — find metrics through:

  • Scale: team size, budget, customers, projects managed
  • Change: before/after comparison, percentage improvement
  • Volume: items processed per time period, annual totals
  • Estimates: use "~", ranges ("8-12"), or "X+" for conservative approximations

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
