GitHub Wiki & Projects Skill

Assists with GitHub Wiki editing and GitHub Project board management for the current repository.

Quick Commands

• /github wiki list — Clone the wiki and list all pages
• /github wiki edit — Edit a specific wiki page
• /github wiki create — Create a new wiki page
• /github projects list — List GitHub Projects for this repo
• /github projects view — View a specific project board

Authentication Reference

GitHub uses three different auth mechanisms depending on the operation. Getting these wrong produces confusing 403 errors.

| Operation | Auth method | Notes | |-----------|------------|-------| | Wiki read (clone) | SSH or HTTPS | Either works | | Wiki push | SSH only | Fine-grained PATs get 403. Always use git@github.com: URL. | | Issues, PRs, releases | gh CLI | Uses the OAuth token from gh auth login | | GitHub Projects (boards) | gh CLI + project scope | Requires gh auth refresh -s read:project,project first |

Before Wiki operations

1. Verify SSH: ssh -T git@github.com
2. Get the repo's remote URL: git remote get-url origin
3. Construct the wiki SSH URL by replacing .git with .wiki.git and ensuring it starts with git@github.com:
4. Clone into your system's temp directory (e.g., /tmp/ on Linux/macOS, %TEMP% on Windows)

Before GitHub Projects operations

The default gh OAuth token lacks project scopes. If gh project list fails with a scopes error, tell the user:

> Your gh token needs the project scope. Run: > `` > gh auth refresh -s read:project,project > ``

Wiki Workflow

1. Clone the wiki into a temp directory using the SSH URL:

``bash git clone git@github.com:/.wiki.git /-wiki ``

1. Edit markdown files using Read/Write/Edit tools
2. Validate — use Grep to check for broken links, TODO markers, stale content
3. Commit and push from the wiki checkout:

``bash git -C add . && git -C commit -m "docs: " && git -C push origin master ``

Wiki repos have a single master branch and no PR workflow — commits push directly.

GitHub Projects Workflow

Detect the repo owner from gh repo view:

OWNER=$(gh repo view --json owner --jq '.owner.login')

# List projects
gh project list --owner "$OWNER"

# View a project
gh project view  --owner "$OWNER"

# Add an issue to a project
gh project item-add  --owner "$OWNER" --url 

Common Pitfalls

• Wiki push 403: You used HTTPS or a fine-grained token. Switch to SSH.
• Project scope error: Run gh auth refresh -s read:project,project.
• Wiki branch confusion: Wiki repos use master, not main.
• Stale wiki clone: Always git pull before editing if the clone already exists.
