At a glance

Builds resumes as valid JSON for the open-source Reactive Resume app by interviewing you, and can track job applications through its MCP tools.

  • Works in 4 steps: Gather Basic Information → Collect Section Content → Configure Layout and Design → …
  • Writing a new resume through a guided conversation
  • SKILL.md covers Core Principles, Related skills, Workflow and Content Essentials, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

This skill guides a conversation that ends in a resume conforming to the Reactive Resume schema. The agent asks for basic details first, then collects each section you want, such as experience, education, skills and projects, with specific fields for each. Its rules forbid inventing dates, employers or achievements, so missing information becomes a question rather than a guess, and the output is validated against the schema.

Through the Reactive Resume MCP server it can also manage job applications: list and create them, import rows from a spreadsheet or CSV, move them between stages, log notes, schedule interviews, attach sent documents, and use the copilot tools to score a match, tailor a resume or draft a message. AI-written cover letters and follow-ups are meant to be reviewed before sending.

When your agent uses it

  • Writing a new resume through a guided conversation
  • Restructuring resume content to fit the Reactive Resume schema
  • Tracking job applications and interviews from the agent

Example prompts

  • “Help me build a resume for a senior data analyst role.”
  • “Import my job applications from applications.csv and set follow-ups.”
  • “Tailor my resume to the backend engineer posting I linked.”

Requirements

  • A Reactive Resume account or instance
  • The Reactive Resume MCP server for application tracking

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather Basic Information
  2. Collect Section Content
  3. Configure Layout and Design
  4. Generate Valid JSON

What it can do on your machine

Read from SKILL.md and the folder at commit c6a7b1d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • rxresu.me

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Reactive Resume Builder loads about 2k tokens when it runs, and up to ~38k if it reads all its reference files. Until then it costs about 180 tokens; SKILL.md has 901 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~180
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~38k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Builds a complete resume from scratch as Reactive Resume JSON that conforms to the schema and imports at https://rxresu.me. Asks for each missing detail instead of inventing it, then produces valid JSON (UUIDs, HTML descriptions, template and layout). Use when the user wants to create, build or generate a new resume, turn their work history into Reactive Resume JSON, or asks about the Reactive Resume schema, sections, templates or layout. For what belongs on a resume or a resume audit use resume-content-guide; for rewriting bullets, resume-bullet-writer; for fitting one job posting, resume-tailor; for tracking applications, job-application-manager; for interviews, interview-prep or mock-interview.

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 invent - Only include information the user provided. Ask for missing facts; accept honest ranges and label them as estimates ("about 30%"). If asked to fabricate, decline in one sentence and offer the honest alternative in the same reply
  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

This skill builds the document. Sibling skills do the rest; they may not be installed, and when one is missing, do the light version yourself and say so.

  • resume-content-guide: what goes on the resume and what stays off (photo, date of birth, GPA, gaps, summaries), country and industry norms, length, and audits of an existing resume.
  • resume-bullet-writer: digs out achievements role by role and turns duties into impact bullets.
  • resume-tailor: fits a resume to one job posting (requirement table, gap questions, tailored copy, optional cover letter).
  • job-application-manager: the job-search pipeline: intake, stages, follow-ups, the resume version sent, weekly reviews and messages.
  • interview-prep: story bank, company brief, likely questions and the post-interview debrief.
  • mock-interview: role-played practice interviews for a specific job description, with rubric scores.
  • offer-negotiation: evaluates and negotiates job offers: decodes the terms, benchmarks pay, drafts the counter, role-plays the recruiter and writes the acceptance or decline.

Workflow

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

Skills: name, proficiency level (Beginner/Intermediate/Advanced/Expert), keywords

Projects: name, period, website (optional), description

Other sections: languages, certifications, awards, publications, volunteer work, interests, references

Step 3: Configure Layout and Design

Ask about preferences:

  • Template preference (17 available: azurill, bronzor, chikorita, ditto, ditgar, gengar, glalie, kakuna, lapras, leafish, meowth, onyx, pikachu, porygon, rhyhorn, scizor, smeargle)
  • Page format: A4 or Letter
  • Which sections to include and their order
Step 4: Generate Valid JSON

Output must conform to the Reactive Resume schema. See references/schema.md for the complete schema structure.

Key requirements:

  • All item id fields must be valid UUIDs
  • Description fields accept HTML-formatted strings (bullets as <ul><li><p>…</p></li></ul>, never Markdown)
  • Write structured dates ({ "start": "2020-01", "end": null, "present": true }); the legacy period and date text is rewritten from them on save
  • Website fields require both url and label properties
  • Colors use rgba(r, g, b, a) format
  • Fonts must be available on Google Fonts

Content Essentials

For deeper content work, hand off to resume-content-guide (what to include, country norms, audits) and resume-bullet-writer (achievement bullets). If neither is installed, apply these core rules:

  • Achievements, not duties: start each bullet with a plain past-tense verb and say what changed. Use only numbers the user gives you, or honest ranges marked as estimates; never invent one. No "I", "my" or "we".
  • Bullets per role: 3–6 for recent roles, 1–3 for older ones.
  • Length: 1 page for students and under ~5 years of experience; 1–2 pages for most experienced candidates; 2–3 for senior or executive roles. US federal (USAJOBS) resumes are 2 pages maximum as of 2026.
  • Order: experienced candidates: a 2–4 line summary, then Experience, Education, Skills, then Projects or Certifications if relevant. Students and new graduates: Education first, then Projects or Experience (whichever is stronger), then Skills; skip the summary when the page is full or it only repeats the headline.
  • Personal data: in the US, UK, Canada and Australia, leave out the photo (picture.hidden: true), date of birth, marital status, full street address and ID numbers. Other countries differ.
  • Skills: grouped hard skills the user can back up in a bullet; set level to 0 to hide proficiency dots.
  • Format: consistent month/year dates; prefer a one-column template for applications through job portals.

Output Format

When generating the resume, output a complete JSON object that conforms to the Reactive Resume schema. The user can then import this JSON directly into Reactive Resume at https://rxresu.me. With the Reactive Resume MCP server connected, offer to create it with import_resume {data} instead, after the user approves; if the payload is too large for the client, give the JSON file.

Example minimal structure:

json
{
  "picture": { "hidden": true, "url": "", "size": 80, "rotation": 0, "aspectRatio": 1, "borderRadius": 0, "borderColor": "rgba(0, 0, 0, 0.5)", "borderWidth": 0, "shadowColor": "rgba(0, 0, 0, 0.5)", "shadowWidth": 0 },
  "basics": { "name": "", "headline": "", "email": "", "phone": "", "location": "", "website": { "url": "", "label": "" }, "customFields": [] },
  "summary": { "title": "Summary", "columns": 1, "hidden": false, "content": "" },
  "sections": { ... },
  "customSections": [],
  "metadata": { "template": "onyx", "layout": { ... }, ... }
}

For the complete schema, see references/schema.md.

MCP Application Tracking

The Reactive Resume MCP server also manages job applications. For pipeline work (adding jobs, moving stages, follow-ups, recording the resume version sent, weekly reviews, messages), use the job-application-manager skill. If it isn't installed:

  • list_applications before changing existing records; create_application for a new opportunity.
  • update_application to move a stage or link a resume; add_application_note to log activity.
  • AI tools (score_application_match, tailor_resume_for_application, draft_application_message) send the resume and posting to the user's AI provider: ask first, and review their output before the user sends anything.

Asking Good Questions

When information is missing, ask specific questions:

  • "What was your job title at [Company]?"
  • "What dates did you work there? (e.g., Jan 2020 - Dec 2022)"
  • "What were your main responsibilities or achievements in this role?"
  • "Do you have a specific target role or industry in mind?"

Avoid compound questions. Ask one thing at a time for clarity.
