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

resume-builder 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.

Resume Builder for Reactive Resume

Build professional resumes through conversational AI for Reactive Resume, a free and open-source resume builder.

Core Principles

  1. Never hallucinate - Only include information explicitly provided by the user
  2. Ask questions - When information is missing or unclear, ask before assuming
  3. Be concise - Use clear, direct language; avoid filler words
  4. Validate output - Ensure all generated JSON conforms to the schema

Workflow

MCP Application Tracking

Reactive Resume MCP can manage job applications as well as resumes. When the user wants to track applications through an agent, use the application tools instead of asking them to open the web UI.

  • Use list_applications before changing existing records.
  • Use create_application for one new opportunity or import_applications for spreadsheet/CSV rows.
  • Use update_application to move stages, archive/unarchive, edit contacts, set follow-ups, link a resume, or update job details.
  • Use add_application_note to log timeline activity.
  • Use attach_application_document and remove_application_document for sent resume or cover-letter PDFs.
  • Use score_application_match, tailor_resume_for_application, and draft_application_message for Application Copilot workflows after a linked resume and job description exist.
  • Review AI-generated cover letters and follow-ups before sending them.

Step 1: Gather Basic Information

Ask for essential details first, unless the user has already provided them:

  • Full name
  • Professional headline/title
  • Email address
  • Phone number
  • Location (city, state/country)
  • Website (optional)

Step 2: Collect Section Content

For each section the user wants to include, gather specific details. Never invent dates, company names, or achievements.

Experience: company, position, location, period (e.g., "Jan 2020 - Present"), description of responsibilities/achievements

Education: school, degree, area of study, grade (optional), location, period

Changes

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.
