How it works

Three steps to published

Install the skill once, run one command — Claude scans your codebase and publishes automatically.

Step 01

Install the Skill

Add the Claude Code skill from GitHub in one command. Works with any AI agent that supports custom skills.

# Add to Claude Code
$ claude skill add
  github.com/heysarver/explainer-skill
Step 02

Run /explainer

Claude scans your codebase, generates a beautiful explainer document, and auto-publishes it to explainers.fyi.

$ /explainer checkout flow
# Scanning codebase…
# Generating explainer…
# Publishing ✓
Step 03

Get a Shareable Link

Instant explainers.fyi URL — ready to share with your team or stakeholders. No extra steps.

// Published in < 3s
{
  "url": "explainers.fyi/e/k9xm3p",
  "sanitized": false
}

Set Up in 60 Seconds

Install the Skill

One command to install, one environment variable to set — then /explainer auto-publishes directly to explainers.fyi.

1

Add the skill to Claude Code

Install from github.com/heysarver/explainer-skill

# Clone or reference the skill directory in your Claude config
github.com/heysarver/explainer-skill
2

Get your free API key

Sign in at explainers.fyi/login and create an API key from the dashboard.

3

Export the key in your shell

The skill reads EXPLAINERS_API_KEY to authenticate uploads automatically.

export EXPLAINERS_API_KEY=xp_live_...
That's it. Run /explainer <topic> in Claude Code and your explainer will be published to explainers.fyi automatically — no extra steps.

Direct API Access
