GitHub Gist Skill

Expert management of GitHub Gists via the gh CLI. All gists created through this skill include a README.md that documents the gist's purpose, content, and optional usage instructions.

Core Rule: README.md is Mandatory

Every gist must contain a README.md file. When creating a new gist, always generate a README.md alongside any other files. When editing a gist that lacks a README.md, add one.

The README.md must include:

• Description — what the gist does or contains
• Content summary — what files are included and what each does
• Usage (optional, include when the gist contains runnable scripts or commands)

See references/readme-template.md for the standard template.

Reference Files

| Reference | When to Load | |-----------|--------------| | references/readme-template.md | Before creating any gist — get the README.md template | | references/workflows.md | For multi-step operations: create with multiple files, bulk edit, clone & modify | | references/search-and-manage.md | For listing, filtering, viewing, or deleting gists |

Quick Reference: Common Operations

Create a new gist (single file)

# Always create README.md first, then create gist with both files
cat > /tmp/README.md << 'EOF'
# <gist title>

<description>

## Files

- `<filename>` — <what it does>

## Usage

<usage instructions if applicable>
EOF

gh gist create --public --desc "<description>" /tmp/README.md <your-file>

Create a gist (multiple files)

gh gist create --public --desc "<description>" README.md file1.sh file2.py

List gists

gh gist list                          # 10 most recent
gh gist list -L 50                    # 50 most recent
gh gist list --public                 # only public
gh gist list --secret                 # only secret
gh gist list --filter "pattern"       # filter by description/filename
gh gist list --filter "pattern" --include-content  # search file contents

View a gist

gh gist view <id>                     # rendered view
gh gist view <id> --raw               # raw content
gh gist view <id> --files             # list filenames
gh gist view <id> --filename README.md
gh gist view <id> --web               # open in browser

Edit a gist

gh gist edit <id>                         # interactive (opens editor)
gh gist edit <id> --filename <file>       # edit specific file
gh gist edit <id> --desc "new description"
gh gist edit <id> --add newfile.py        # add a file
gh gist edit <id> --remove oldfile.py     # remove a file

Clone a gist locally

gh gist clone <id> [<directory>]

Delete a gist

gh gist delete <id>

Workflow: Creating a Gist

When a user asks to create a gist, follow these steps:

1. Gather information — determine the description, files involved, and whether it should be public or secret (default: secret)
2. Generate README.md — always write a README.md using the template in references/readme-template.md
3. Assemble files — write the actual script/content files if they don't already exist
4. Create the gist — use gh gist create with all files, including README.md
5. Confirm and report — show the user the gist URL

Always load references/readme-template.md before writing the README.md.

Workflow: Adding Files to an Existing Gist

When adding files to a gist:

1. Check if a README.md exists: gh gist view <id> --files
2. If missing, create one with gh gist edit <id> --add README.md
3. Add the new file: gh gist edit <id> --add <filename>
4. Update the README.md to document the new file

Determining Visibility

• Secret (default): private to owner, accessible by URL. Use when the content is personal or sensitive.
• Public (--public): listed publicly. Use when the intent is sharing with the community.

Ask the user if unclear. Default to secret.

File Naming Convention

• Scripts: use the appropriate extension (.sh, .py, .rb, .js, etc.)
• Config snippets: use the actual config filename (e.g., .zshrc, nginx.conf)
• Documentation: always README.md (never readme.txt or README.txt)
• One-liners or reference cards: use .md format for readability

Error Handling

| Error | Resolution | |-------|-----------| | gh: not authenticated | Run gh auth login | | File not found | Verify path; use absolute paths in /tmp/ for temp files | | Gist ID not found | Run gh gist list to find the correct ID | | Rate limited | Wait and retry; use --limit to reduce API calls |

---

Tip: Use gh gist view <id> --web to open any gist in the browser for easy sharing.
