CVX

Structured input. Professional output. To the power of X.

CI npm version npm downloads install size license

CVX turns plain YAML into a professionally designed CV PDF — one command, fully local, no accounts; your data never leaves your machine. Use it two ways: edit the YAML yourself, or have any AI assistant write it for you from your existing CV — CVX validates the files and tells the assistant exactly what to fix.

🤖 AI assistants: if a user asked you to create their CV with CVX, follow the default flow in the AI guide (section "Default flow (for assistants)"). Non-negotiables even if you skip the link: never invent facts — every entry must be truthful to the user's input; linkedin.com URLs are unfetchable even when public — don't infer, ask for the profile's More → Save to PDF export or pasted text instead; ask for a square photo in your first reply (it can't be generated; the CV renders fine without one); and CVX is the only renderer — never substitute another PDF generator.

No terminal? No problem. Paste this into any AI chat (Claude, ChatGPT, Gemini, …):

Create my CV with https://github.com/hrtips/cvx — open that page and follow its instructions for AI assistants.
Here is my LinkedIn profile: <your profile URL> (or attach your current CV and a photo instead).

Designed two-column CV produced by CVX — teal theme, photo sidebar, achievements

The scaffolded example CV, exactly as npx @hrtips/cvx build renders it — plus an ATS-safe single-column variant via --ats.


Create your CV in two minutes

npx @hrtips/cvx init     # scaffold cv-content/ with a complete example CV
npx @hrtips/cvx build    # render it to a PDF

init gives you a finished, working CV — Bruce Wayne's, and yes, really. Open bruce-wayne.pdf and you're looking at a designed two-page CV: photo, sidebar, achievements, the lot.

Now make it yours. Open the cv-content/ folder, and replace Bruce's details with your own, one file at a time:

cv-content/
  personal.yaml       ← start here: your name, title, contact details
  summary.yaml        ← the bullet points at the top of page 1
  experience.yaml     ← your work history (the bulk of the CV)
  education.yaml      ← degrees, institutions, years
  competencies.yaml   ← skill pills in the sidebar
  achievements.yaml   ← awards and recognitions
  referees.yaml       ← referees, or [] for "available upon request"
  images/profile.jpg  ← your photo (square, 400×400px or larger)

Re-run npx @hrtips/cvx build after each file and watch the PDF update — seeing Bruce's entry next to yours makes the format self-explanatory. The output file is named after you automatically (jane-doe.pdf).

Made a typo or unsure a file is right? npx @hrtips/cvx validate checks everything at once and tells you exactly what to fix:

cv-content/personal.yaml
  ⚠ unknown key "linkdin"
      ↳ did you mean "linkedin"?

Every scaffolded file also carries a $schema header, so editors with YAML support (VS Code + the YAML extension, JetBrains, …) autocomplete keys and flag mistakes as you type.

Applying through a job portal? Generate the ATS-safe variant too — single column, no colours, machine-friendly:

npx @hrtips/cvx build --ats

CLI reference

Command Does
npx @hrtips/cvx init Scaffold cv-content/ with the example CV (won't overwrite an existing one)
npx @hrtips/cvx validate Check cv-content/ — every problem at once, with file + field paths and fixes
npx @hrtips/cvx validate --strict Also fail on warnings (unknown keys); recommended for agents/CI
npx @hrtips/cvx build Render cv-content/ to <your-name>.pdf
npx @hrtips/cvx build --ats Render the ATS-safe single-column variant
npx @hrtips/cvx list Show available themes and layouts
npx @hrtips/cvx --help / --version Help / version

All commands accept --json for machine-readable output (one JSON object on stdout, logs on stderr) and use semantic exit codes: 0 ok, 2 validation failed, 3 render failed, 64 usage error. init is a convenience, not a prerequisite — build renders any cv-content/ folder with valid YAML (built-in themes and layouts need no extra files).

Compatibility promise: content files are versioned by schemaVersion in config.yaml (currently 1) and validated against the canonical JSON Schema. Within a schema major version, your content files never break — new keys may appear, existing ones keep working. npx @hrtips/cvx validate on today's files will still pass on every future 1.x release.


What goes in each file

These are excerpts from the scaffolded example — build it once and you can see exactly where each snippet lands on the page.

personal.yaml — the header and contact block:

name: Bruce Wayne
title: Founder & Field Commander – Gotham Operations
company: Wayne Enterprises
phone: "+1 (201) 555-2283"
phoneHref: "tel:+12015552283"
email: [email protected]
linkedin: linkedin.com/in/brucewayne
linkedinHref: "https://www.linkedin.com/in/brucewayne"

experience.yaml — one entry per role; progression (optional) renders a title history inside the entry:

- role: Founder & Field Commander – Gotham Operations
  company: The Batman
  period: 2005 – Present
  description: Self-directed vigilante operation safeguarding Gotham City through deterrence, investigation, and crisis response.
  progression:
    - title: Commander, Batman Incorporated
      period: 2011 – Present
    - title: Solo Operative, The Dark Knight
      period: 2005 – 2008
  bullets:
    - Established and scaled a citywide security operation from a solo initiative to a franchised network (Batman Incorporated).
    - Recruited, trained, and led a high-performing field team including Robin, Nightwing, and Batgirl.
    - Reduced organised-crime activity in Gotham by an estimated 60% through data-driven surveillance and rapid incident response.

summary.yaml — the bullet list at the top of page 1:

- "Strategic operations leader with 20+ years' experience, progressing from solo field operative to Field Commander of a citywide security network."
- "Co-founded the Justice League as a global response coalition, serving as chief strategist and contingency planner for existential-scale threats."

education.yaml

- degree: "Applied Sciences & Criminology (self-directed)"
  institution: League of Shadows
  period: 1998 – 2004

- degree: BSc, Criminology & Chemistry
  institution: Gotham University
  period: 1994 – 1998

competencies.yaml — rendered as skill pills in the sidebar:

- Strategic Planning
- Criminal Investigation
- Crisis Response
- Surveillance & Intelligence

achievements.yaml

- year: Gotham's Most Influential Citizen
  text: "— 2024, Gotham Gazette"

- year: Key to the City
  text: "— Office of the Mayor, Gotham City"

referees.yaml (use [] to print "available upon request"):

- name: Diana Prince
  title: Founding Member, Justice League
  company: Themysciran Embassy
  email: [email protected]
  phone: "+1 (202) 555-0177"

Delete what you don't need — an empty file (or []) simply drops that section from the CV. Any new .yaml file you drop into cv-content/ is auto-discovered as a content key.

The complete field-by-field schema for every file lives in docs/cv-schema.md.

Let an AI write the YAML for you

The formats are deliberately LLM-friendly, and the schema is published for machines (llms.txt, docs/cv-schema.md). The AI guide has copy-paste prompts for every route; the short version:

Coding agent (Claude Code, Cursor, …) — lowest friction: run npx @hrtips/cvx init, then ask the agent to replace the example content with your details and build. The scaffolded cv-content/README.md documents the schema, so the agent edits, runs npx @hrtips/cvx build, and fixes errors itself.

Chat assistant (Claude, ChatGPT, …) — paste your existing CV or LinkedIn profile text along with this prompt:

Read the CVX content schema at https://raw.githubusercontent.com/hrtips/cvx/main/docs/cv-schema.md then convert my CV below into CVX cv-content/ YAML files. Output each file in its own fenced code block titled with the filename. Keep every fact truthful to my input — don't invent anything.

Save the generated files into cv-content/, drop in your photo, run npx @hrtips/cvx build. No web access in your assistant? Use the self-contained prompt.

Plug it into your agent (MCP)

CVX ships an MCP server — any MCP client (Claude Desktop, Claude Code, Cursor, VS Code, …) can drive the whole loop with four tools: get_schema, init_cv, validate_cv, build_pdf. No API keys, fully offline.

npx @hrtips/cvx mcp init --client claude          # Claude Code (.mcp.json, project)
npx @hrtips/cvx mcp init --client claude-desktop  # Claude Desktop (global config)
npx @hrtips/cvx mcp init --client cursor          # Cursor (.cursor/mcp.json)
npx @hrtips/cvx mcp init --client vscode          # VS Code (.vscode/mcp.json)

Then restart the client and ask it to make your CV — it fetches the schema, scaffolds, fills in your details, validates after every edit, and renders the PDF. The config writer merges into existing files; it never clobbers other servers. There's also a ready-made Agent Skill with the same loop for skill-capable agents.

Your photo

Drop it into cv-content/images/ as profile.<ext>jpg, jpeg, png, or webp are auto-detected (that order wins if several exist). Square crop, at least 400×400px.


Themes, layouts, and page flow

Everything visual is controlled by cv-content/config.yaml:

theme: teal               # teal | coral | mono
layout: two-column        # two-column | single-column
page1ExperienceCount: 2   # experience entries on page 1
page1SplitBullets: 2      # split the last entry: N bullets on page 1, rest continue

Change a value, re-run npx @hrtips/cvx build, done.

Themes control colour and styling:

Theme Accent Description
teal #1a6070 Professional teal (default)
coral #c0534a Warm coral red
mono #000000 Black and white, ATS-optimised

Layouts control page structure:

Layout Structure Description
two-column Sidebar + main column Designed CV with photo, identity block, achievements
single-column Full width ATS-safe, no sidebar, no decorative elements

Pagination — experience entries are distributed across pages automatically (greedy bin-packing). Set page1ExperienceCount / page1SplitBullets to control page 1 explicitly. Example with 6 entries and the config above:

  • Page 1 — Summary + Entry 1 (full) + Entry 2 (first 2 bullets)
  • Page 2 — Entry 2 (cont'd) + Entries 3–6

Custom layouts

You can define your own page structure — drop a .yaml file into cv-content/layouts/ and reference it by filename:

# cv-content/layouts/compact.yaml
template: two-column

pages:
  first:
    sidebar:
      - identity-photo
      - contact
    main:
      - summary
      - spacer: 27
      - experience

  continuation:
    sidebar:
      - identity-compact
      - education
      - competencies
      - achievements
    main:
      - experience:continued

  last:
    sidebar:
      - identity-compact
      - referees
    main:
      - experience:continued

Then set layout: compact in config.yaml. Available section keys:

Key Renders
identity-photo Name, title, company + profile photo (sidebar)
identity-compact Name, title, company without photo (sidebar)
contact Phone, email, LinkedIn, location with icons (sidebar)
achievements Year + description list (sidebar)
education Degree, institution, period (sidebar)
competencies Skill tags as pills (sidebar)
referees Referee contact details (sidebar)
summary Bullet point list (main column)
experience Experience entries for page 1 (main column)
experience:continued Continuation experience entries (main column)
header-ats Full-width name/title/contact header (single-column)
spacer: N Vertical spacer of N points

ATS & AI-parser keywords

Both PDFs embed a keyword list into the standard Keywords metadata field — the field some applicant tracking systems (ATS) and AI CV parsers read. Keywords live in metadata, not as hidden text on the page.

Reality check: most mainstream ATS rank on text extracted from the CV body, and support for the PDF Keywords/XMP field is inconsistent. Treat this as a best-effort supplement to a keyword-rich body — not a substitute, and not a reliable ranking lever on its own. Keep every keyword truthful; stuffing false or irrelevant terms causes a metadata/body mismatch that gets a CV auto-rejected.

Keywords come from two sources, merged and de-duplicated (body-derived terms first):

  1. Auto-derived from your competencies.yaml and job titles (company names are deliberately excluded as low-signal).
  2. Curated in cv-content/keywords.yaml — a flat list, or grouped under headings:
# cv-content/keywords.yaml
- Operations Management
- Risk Management
# …or grouped:
Leadership: [Executive Leadership, Team Building]

Configure in config.yaml:

atsKeywords:
  enabled: true       # master switch                                  (default: true)
  autoDerive: true    # also derive from competencies + job titles      (default: true)
  max: 40             # optional cap; body-derived terms are kept first (default: all)


For developers

Everything below is about hacking on CVX itself — custom themes, the rendering pipeline, and contributing. You don't need any of it to create a CV.

Working from a clone

git clone [email protected]:hrtips/cvx.git
cd cvx
npm install
npm run dev        # live browser preview at http://localhost:5173
npm run pdf        # generate PDF (same pipeline as `cvx build`)
npm run pdf:ats    # generate the ATS variant
npm test           # unit tests
npm run build:lib  # build the publishable lib/ (what the CLI runs)

The repo's cv-content/ carries the same Bruce Wayne example, so a clone builds out of the box. A photo crop helper is included: python3 scripts/crop-profile.py path/to/photo.jpg.

Custom themes

Themes ship inside the package, so custom themes currently require working from a clone — the npx CLI offers the three built-ins.

Drop a .js file in src/pdf/themes/ — it's auto-discovered, no registration needed:

// src/pdf/themes/navy.js
import { tealTheme } from './teal.js'

export const navyTheme = {
  ...tealTheme,
  name: 'navy',
  palette: {
    ...tealTheme.palette,
    accent:    '#1e3a5f',
    sidebarBg: '#eef1f5',
    tagBg:     '#d0d8e8',
    tagText:   '#1e3a5f',
    divider:   '#b8c4d4',
  },
}

Set theme: navy in config.yaml. The theme object has five namespaces you can override:

Namespace Controls
palette All colours — accent, backgrounds, text, tags, dividers, semantic opacity colours
typography Font sizes, weights, letter spacing, line heights per element
spacing Gaps, margins, padding values used by all components
chrome Decorative dimensions — border radii, divider widths, photo size, corner badge
geometry Page dimensions, column fractions, padding objects

Auto-discovery

Convention over registration — drop a file in the right folder and it's picked up:

What Where to drop it How it's found
Content cv-content/*.yaml Any .yaml file (except config.yaml) becomes a content key matching its filename
Themes src/pdf/themes/*.js Any .js file exporting an object with a name property
Layouts cv-content/layouts/*.yaml Any .yaml file with a template and pages structure
Profile photo cv-content/images/profile.* First match of .jpg, .jpeg, .png, .webp

To add a whole new content section (e.g. publications): create cv-content/publications.yaml (auto-available as content.publications), build a section component in src/pdf/sections/, register it in registry.js, then reference it from a layout.

Architecture

Three concerns, independently swappable:

Content (YAML)  ×  Theme (JS)  ×  Layout (YAML)
     ↓                ↓               ↓
  what to say    how it looks    where it goes

The rendering pipeline:

config.yaml → resolves theme + layout
    ↓
cv-content/*.yaml → auto-loaded into data bag
    ↓
layout.js → packs experience entries across pages (using theme metrics)
    ↓
CVDocument → picks template (TwoColumn or SingleColumn)
    ↓
template → renders slots from layout config via section registry
    ↓
sections → read theme from React context, render content
    ↓
@react-pdf/renderer → PDF buffer → file

Project structure

cv-content/                      ← content (the repo carries the example CV)
  *.yaml                         ← auto-discovered content files
  config.yaml                    ← theme, layout, pagination
  layouts/                       ← auto-discovered layout definitions
  images/profile.<ext>           ← photo (jpg/jpeg/png/webp)

src/pdf/                         ← framework
  CVDocument.jsx                 ← unified config-driven document
  ATSDocument.jsx                ← standalone ATS document
  ThemeContext.jsx               ← React context + useStyles hook
  render.js                      ← shared render pipeline (CLI + scripts)
  layout.js                      ← theme-aware page-packing + sidebar resolution
  keywords.js                    ← ATS/AI-parser keyword metadata
  reproducible.js                ← SOURCE_DATE_EPOCH support (see below)
  profilePhoto.js                ← shared profile-image extension precedence
  loadContent.js                 ← auto-discovers cv-content/*.yaml
  loadLayout.js                  ← normalizes layout YAML → slot config
  fonts.js                       ← Lato font registration
  *.test.js                      ← Vitest unit tests (co-located)
  themes/                        ← auto-discovered themes (teal, coral, mono)
  templates/                     ← page shells (TwoColumn, SingleColumn)
  sections/                      ← content sections + registry
  components/                    ← shared leaf components

scripts/
  export-pdf.js                  ← npm run pdf
  export-pdf-ats.js              ← npm run pdf:ats
  build-lib.js                   ← npm run build:lib (publishing build)
  crop-profile.py                ← photo crop helper

bin/cvx.js                    ← npx CLI (init / build)
template/cv-content/             ← starter content scaffolded by `cvx init`
lib/                             ← generated: published transform of src/pdf (gitignored)

Testing

npm test

Unit tests cover the pure logic modules — keyword building, page packing, sidebar resolution, reproducibility helpers, and the profile-photo picker. Tests live next to the code they cover (src/pdf/*.test.js) plus test/ for cross-cutting checks. CI runs the suite on Linux and macOS across Node 20/22/24 (plus Windows on Node 22), then packs the tarball and exercises the installed CLI end-to-end, including a byte-identical reproducibility gate.

Reproducible builds

Set SOURCE_DATE_EPOCH (seconds since the Unix epoch) to make PDF output byte-identical run after run — useful for CI checks and for verifying that a content change is the only thing that changed:

SOURCE_DATE_EPOCH=$(git log -1 --format=%ct) npx @hrtips/cvx build   # or npm run pdf

This pins the PDF's CreationDate (and with it the trailer file ID), the font-subset names, and the object write order — the things that otherwise vary per run. Unset, builds behave normally and stamp the current time.

Byte-identical output is guaranteed for the same platform and Node version. Builds from different OSes or Node majors are visually identical but not byte-identical (font subsets embed in a platform-dependent order, and zlib output varies across Node versions).

Tech stack

  • @react-pdf/renderer — renders React to PDF (no headless browser)
  • Vite + React — live browser preview
  • js-yaml — YAML parsing (pinned to 4.x to match @rollup/plugin-yaml)
  • esbuild — transform-only build of lib/ for publishing
  • tsx — runs the repo export scripts
  • Vitest — unit tests
  • Lato — embedded font (Light 300, Regular 400, Bold 700)
