What it does
Gh Attach is an agent skill from sickn33/agentic-awesome-skills. Upload and download GitHub user-attachments (screenshots, PDFs, zips, videos) from the terminal; use when asked to attach or embed a file in a PR, issue, or comment, or download an attachment URL.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office. It works with GitHub. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Asked to attach
- Embed a file in a PR
- Download an attachment URL
Example prompts
- “/gh-attach”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gh Attach loads about 1.6k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 727 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Upload and download GitHub user-attachments (gh-attach)
GitHub has no public API for user-attachments. The web UI uses an internal
endpoint that mints github.com/user-attachments URLs whose visibility follows the
repository they belong to. gh-attach
(MIT, sudosubin) replicates that drag-and-drop flow as a gh CLI extension, so an
agent can upload a local file from the terminal, get a URL back, and later download
an attachment URL to a file.
Overview
This skill drives gh-attach to turn a local file (screenshot, image, PDF, zip,
log, or video) into a hosted GitHub user-attachments URL, then embeds that URL
into a pull request, issue, or comment. It also downloads an existing attachment
URL back to a local file. GitHub auto-renders the URL as an image, video, or file
wherever it is pasted, and the URL inherits the repository's visibility, so a
private-repo upload stays private. It works against GitHub Cloud and GitHub
Enterprise Server.
When to Use This Skill
Use this skill when asked to:
- "Attach a screenshot to the PR" or "add an image to the PR description"
- "Attach this file (PDF, zip, log, video) to the issue or comment"
- "Embed before/after screenshots" in a PR, issue, or README
- "Download this GitHub attachment" from a
user-attachmentsURL
How It Works
Step 1: Verify prerequisites
gh auth status # gh installed and authenticated
gh extension install sudosubin/gh-attach --pin v0.4.2 --force
gh extension list | grep -F 'sudosubin/gh-attach' # require the reviewed v0.4.2 releaseUploads use a GitHub user_session browser cookie, not the gh token (that
endpoint rejects tokens). By default gh must be authenticated so gh-attach can
select the matching browser account (Chromium family, Firefox family, or Safari).
If the wrong account is selected, add --browser <name> --profile <name>. Obtain
explicit approval before allowing the pinned extension to access that interactive
browser profile. Headless and CI uploads are intentionally unsupported: never export,
store, or pass a raw user_session cookie to the extension.
Step 2: Upload
# Use an absolute quoted path; -R is optional inside a repo working dir.
URL=$(gh attach "/abs/path/screenshot.png" -R <owner>/<repo>)gh attach prints the URL on one line to stdout. For GitHub Enterprise Server,
use -R host/owner/repo. Capture the output; it is the embeddable reference.
Step 3: Embed into the PR / issue / comment
printf '## Screenshots\n\n%s\n' "$URL" \
| gh pr comment <pr> -R <owner>/<repo> --body-file -Use gh pr edit, gh issue comment, or gh issue edit with --body-file - for
other targets. Always pass --body-file - (not inline --body) so multi-line
bodies and special characters cannot break shell quoting. GitHub auto-renders the
URL, so paste it as-is.
Step 4: Download
# Specify the destination explicitly.
gh attach download "$URL" -O "/abs/path/out.png"Downloads of private attachments use the active gh token, with browser cookies as
an authorization fallback.
Examples
- Attach a screenshot to PR #42: upload the file, then append the URL under a
## Screenshotsheading in the PR body withgh pr edit ... --body-file -. - Embed before/after screenshots in a README: upload both files, paste the two URLs into the README at the relevant section.
- Download an attachment for review: run
gh attach download "$URL" -O out.zipto fetch auser-attachmentsfile locally.
Show full SKILL.md (277 more words)Show less
Best Practices
- Resolve globs to absolute paths first, and quote paths that contain spaces or Unicode.
- For display sizing, embed an HTML tag instead of the bare URL:
<img width="800" src="$URL">. - Keep uploads interactive. Do not place a GitHub browser session in CI, an environment variable, a secret store consumed by this extension, or an agent log.
gh-attachcan upload multiple files concurrently and emit Markdown or JSON output with jq-style filtering when you need to script around the result.
Limitations
- Interactive session cookie required. A
user_sessioncookie grants full account access and is not scoped like a PAT. The supported path is the reviewed, pinned extension reading an explicitly approved local browser profile; CI and headless cookie injection are out of scope. - Write access to the target repo is required to upload.
- Private-repo attachments stay private: the
user-attachmentsURL inherits repo visibility, so an anonymous fetch on a private repo returns 404 or 403 by design. - GitHub Cloud and GitHub Enterprise Server each decide which file extensions and content types they accept.
- The skill embeds the URL itself;
gh attachonly prints it.
Security & Safety Notes
- The
user_sessioncookie is a full-account credential. Never print, export, paste, log, or commit it, and never make it available to CI or headless agents. - Do not install or upgrade
gh-attachfrom a moving branch or an unpinned latest release. Re-review and update the exact--pinonly in a repository change. - Uploaded attachments are auto-rendered by GitHub, so only upload files you intend to share with everyone who can view the target repository.
- Confirm the destination
-R <owner>/<repo>before uploading so an attachment is not created against the wrong repository.
