DevCard

Auto-generate beautiful, agent-readable developer identity cards from GitHub.

No sign-up. No scraping. Paste a GitHub username -- get a visual card, structured JSON, AI-powered insights, and terminal output in seconds.

Why DevCard?

We optimize GitHub profiles for humans -- clean READMEs, pinned repos, contribution graphs. But AI agents are already evaluating developer capabilities, and they're scraping GitHub the same ad-hoc way we scraped resumes 10 years ago.

DevCard creates a structured protocol for developer identity. A devcard.json that says "I'm an ML engineer who ships production PyTorch, with 95% test coverage across my repos" -- readable by both humans and machines.

• 14+ signals extracted from public GitHub data (languages, stack, activity, code quality, collaboration style)
• Dual scoring -- Human Visibility (recruiters) + Agent Readiness (AI tools)
• MCP server -- AI agents query developer profiles as structured data, not scraped HTML

Quick Start

pip install devcard

# (Recommended) Set your GitHub token for 5000 req/hr instead of 60
export GITHUB_TOKEN=$(gh auth token)

# Generate your card
devcard generate YOUR_USERNAME

# Get an SVG for your GitHub README
devcard generate YOUR_USERNAME --format svg --theme dark

# Get actionable profile advice
devcard advise YOUR_USERNAME

# Compare two developers
devcard compare karpathy torvalds

What It Extracts

DevCard analyzes public GitHub data to build a structured developer profile with 14+ signals:

Signal	Source	Example
Identity	User profile	Name, bio, location, followers
Languages	Repo language stats	Python 72% (logic), CSS 8% (presentation)
Tech Stack	Dependency files	PyTorch, FastAPI, PostgreSQL
Activity	Events + search API	Active, 679 commits/year, consistency 75/100
Top Projects	Repos ranked by impact	Signature project with narrative
Collaboration	PRs, issues, orgs	Maintainer style, external contributions
Quality	Repo file structure	CI 80%, tests 60% + actionable recommendations
Expertise	Topics + stack + stars	Machine Learning (0.95, advanced)
Notable Contributions	PRs to popular repos	Merged PRs in keras, flask, kubernetes
Coding Habits	Commit patches	Spaces indentation, 39 chars/line avg
Commit Quality	Commit messages	Avg 160 chars, 20% multi-line
README Depth	README content analysis	748 words avg, 78% have code blocks
Code Reviews	PR review events	5 reviews given, 3 approved
Responsiveness	Comment events	Issue comments, PR discussion activity

All signals are extracted from public GitHub API data.

Commands

devcard generate <username>

Generate a DevCard for any public GitHub user.

devcard generate torvalds                              # Terminal output (default)
devcard generate torvalds --format svg --theme dark    # Dark SVG card
devcard generate torvalds --format json -o out.json    # Save JSON to file
devcard generate torvalds --token ghp_xxx              # Explicit token
devcard generate torvalds --enrich                     # AI-powered insights
devcard generate torvalds --no-cache                   # Fresh data
devcard generate torvalds --verbose                    # Debug logging

devcard advise <username>

Get actionable profile advice with scores, praise, and critiques.

devcard advise chiruu12                    # Rules-based advice (no LLM needed)
devcard advise chiruu12 --enrich           # Add LLM-generated summary
devcard advise chiruu12 --format json      # Machine-readable advice
devcard advise chiruu12 --format markdown  # GFM output

Outputs:

• Human Visibility Score (0-100) -- how visible to recruiters
• Agent Readiness Score (0-100) -- how readable by AI tools
• Verdicts -- praise (what's good), critiques (what to fix), suggestions (nice-to-have)
• Each critique includes a specific action to fix it

devcard compare <user1> <user2>

Compare two developers side by side.

devcard compare karpathy torvalds             # Terminal comparison
devcard compare karpathy torvalds --format json   # JSON with both cards

devcard validate <file>

Validate a devcard.json against the schema.

devcard validate my-devcard.json

devcard me

Generate a DevCard for your own GitHub account (detected via gh CLI).

devcard me --format svg --theme neon

Output Formats

devcard generate <username> --format terminal   # Rich terminal panels (default)
devcard generate <username> --format json        # Structured devcard.json
devcard generate <username> --format yaml        # Human-friendly YAML
devcard generate <username> --format svg         # Embeddable SVG card
devcard generate <username> --format markdown    # GitHub Flavored Markdown
devcard generate <username> --format agent       # Machine-readable key:value
devcard generate <username> --format llms-txt    # llms.txt spec for AI agents
devcard generate <username> --format all         # Everything at once

Made for AI Agents

DevCard outputs are designed for machine consumption, not just human eyes.

devcard generate torvalds --format agent      # Key:value pairs for AI tools
devcard generate torvalds --format llms-txt   # llms.txt protocol spec
devcard generate torvalds --format json       # Structured devcard.json

DevCard ships as an MCP server, so AI agents like Claude can query developer profiles directly:

# An AI agent calls:
get_devcard("torvalds")  # Returns typed fields for every signal
compare("karpathy", "torvalds")  # Side-by-side structured comparison

See devcard-mcp/README.md for MCP setup.

AI Enrichment (Optional)

With a Fireworks API key, --enrich adds LLM-powered analysis:

• Developer archetype -- creative label like "ML Craftsman" or "Full-Stack Polyglot"
• AI summary -- 1-2 sentence narrative citing your actual projects
• Evidence-backed strengths -- "Strong ML foundations -- uses PyTorch across 3 projects"
• Actionable suggestions -- "Add CI to FungiClassifier -- it's your top project"
• Smart project ranking -- by significance, not just star count

export FIREWORKS_API_KEY=your-key
pip install devcard[enrich]                            # Install AI dependencies
devcard generate karpathy --enrich                     # Generate with AI insights
devcard advise chiruu12 --enrich                       # Advice with AI summary

Themes

Default	Dark
Minimal	Neon
Terminal Green

Add DevCard to Your GitHub Profile

1. Generate your SVG:

   devcard generate YOUR_USERNAME --format svg --theme dark -o devcard.svg
   

2. Add devcard.svg to your profile repo (YOUR_USERNAME/YOUR_USERNAME)

3. Reference it in your README.md:

   <p align="center">
     <img src="devcard.svg" alt="My DevCard" width="495">
   </p>

The devcard.json Schema

Every DevCard produces a devcard.json -- a structured, agent-readable profile:

{
  "$schema": "https://devcard.dev/schema/v1",
  "version": "1.0",
  "identity": {
    "username": "karpathy",
    "name": "Andrej Karpathy",
    "bio": "I like to train neural nets",
    "followers": 95000
  },
  "languages": [
    { "name": "Python", "percentage": 72.3, "category": "logic" }
  ],
  "expertise": {
    "domains": [
      { "name": "Machine Learning", "confidence": 1.0, "skill_level": "expert" }
    ],
    "profile_type": "ml"
  }
}

The full schema is at schema/devcard.v1.schema.json.
