Add GitHub Image Hosting skill

What problem it solves

GitHub has no API for uploading images from CLI tools. Agents building PRs and issues can't attach screenshots, diagrams, or mockups because ![](./local-file.png) doesn't work — GitHub needs a hosted URL. Traditional image hosts (Imgur, Cloudinary) require API keys and account signup, which agents can't do autonomously.

Who uses this workflow

AI coding agents (Claude Code, Codex, Copilot) and developers who need to embed images in GitHub markdown from the terminal.

How it works

One curl command uploads an image to img402.dev and returns a public CDN URL. The skill then embeds that URL in PRs, issues, or comments via gh CLI. No account, no API key, no auth.

Tiers (free is the default; paid tiers use x402, no signup either way):

Tier	Price	Max size	Retention
Free	$0	1 MB	7 days
1-year	$0.01 USDC	5 MB	1 year
Permanent	$1.00 USDC	5 MB	Permanent

Example

curl -s -X POST https://img402.dev/api/free -F image=@screenshot.png
# → {"url":"https://i.img402.dev/aBcDeFgHiJ.png", ...}

gh pr comment --body "![Screenshot](https://i.img402.dev/aBcDeFgHiJ.png)"

Inspired by: github.com/cli/cli#1895 — long-standing request for image uploads in the GitHub CLI

Updated this PR to v1.1 of the skill — the service has shipped meaningful upgrades since this was opened in February:

Two optional paid tiers alongside the free one: $0.01 USDC for 5MB/1-year retention, $1 for permanent hosting. Paid via x402 — still no account or API key, so agents can use it fully autonomously.
The service is now indexed in the Coinbase CDP Bazaar and listed on ClawHub (~1k installs of this skill there).
Skill source is maintained at img402/skills.

The diff now reflects the current skill. Happy to adjust anything to fit the list's conventions.
