The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 20, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · dcede74

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 20, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Executed the bundled upload.sh against a repository the test account owns: it fetched the gh token, auto-resolved the repository ID, POSTed the binary to GitHub's undocumented uploads.github.com/user-attachments endpoint, and got HTTP 201 back with a canonical github.com/user-attachments/assets/<uuid> URL. A no-skill baseline can't produce that, since the standard answer is 'drag the file into the web UI' because this endpoint is absent from the public REST docs. Error paths are clean too: a missing file and an unsupported extension both fail fast with clear messages. It beats the baseline on a real, verified upload.

What Attach GitHub Assets does

Uploads local images and videos to GitHub's user-attachments store and returns markdown-ready URLs for PR descriptions, issue bodies, and comments. Self-invokes only when a concrete local file path for a supported image or video type is in context and the destination is GitHub. Wraps a single upload.sh that auto-detects the repo ID and MIME type.

How to install Attach GitHub Assets

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
