CGD Dev Identity¶

Overview¶

Perform git and gh write operations for creative-graphic-design organization repositories as the creative-graphic-design-dev machine user (user ID 176740601), not a personal account. A bot-authored PR lets a human account formally review and approve it. Because GitHub does not permit users to approve their own PRs, creating a PR with a personal account would prevent the review flow from working.

Setup¶

Before starting write operations, perform the following checks in the working shell and worktree. Run them as a starting procedure rather than investigating only after a failure.

1. For repository writes, confirm that git remote get-url origin points to github.com/creative-graphic-design.

If it does not, this skill does not apply; use normal git identity and authentication. New-machine setup-gh-cgd bootstrap is exempt.

1. Ensure that GitHub CLI has the bot account in its system credential store. On a new machine, run the interactive setup command once and authenticate in the browser as creative-graphic-design-dev:

setup-gh-cgd

Do not use gh auth switch during agent work. It changes the active account for the whole host and can race with concurrent sessions.

1. Retrieve the stored bot token by account name and pass it only to each write command that uses gh or git credentials:

GH_TOKEN="$(gh auth token --hostname github.com --user creative-graphic-design-dev)" gh pr create ...
GH_TOKEN="$(gh auth token --hostname github.com --user creative-graphic-design-dev)" git push

Do not export the token into a persistent shell and do not print it. The per-command prefix keeps account selection explicit and avoids changing GitHub CLI's global active account.

1. Verify the GitHub identity and push permission for the organization repository. gh api user only confirms the logged-in account and cannot verify access to organization resources:

GH_TOKEN="$(gh auth token --hostname github.com --user creative-graphic-design-dev)" gh api user --jq .login
GH_TOKEN="$(gh auth token --hostname github.com --user creative-graphic-design-dev)" gh api repos/creative-graphic-design/<repo> --jq .permissions.push

Do not start write operations unless the first command returns creative-graphic-design-dev and the second returns true.

1. Set the commit author to the bot for each commit command:

git -c user.name=creative-graphic-design-dev \
    -c user.email=176740601[email protected] \
    commit ...

Do not use git config user.name/email in a linked worktree: it writes to the shared .git/config and changes the author for the main checkout and concurrent worktrees as well.

1. Push over HTTPS because SSH does not use the proxy in this environment. Set an explicit push URL:

git remote set-url --push origin https://github.com/creative-graphic-design/<repo>

GH_TOKEN applies to both gh and the git credential helper in the same command environment. The credential helper returns the token with the username x-access-token.

Scope¶

• This skill applies only to creative-graphic-design organization repositories on github.com. Do not use the stored bot credential or the bot commit identity for other hosts, organizations, or personal repositories; use normal authentication and the normal git identity there.
• Attribute every coding-agent write to a creative-graphic-design organization repository to the bot. This includes commits, pushes, PR creation and updates, PR replies, issue comments, labels, milestones, and user-requested merges.
• If any Setup verification fails, abandon the bot identity entirely: do not apply it partially, such as setting the bot commit author while the credential check failed or pushing through another account. Stop and report instead.
• The human (shunk031) retains only PR approval in the GitHub UI and the decision to merge. Do not approve PRs as the bot.

Troubleshooting¶

• If gh auth token --user creative-graphic-design-dev fails or the stored credential is rejected, remove that account with gh auth logout --hostname github.com --user creative-graphic-design-dev, then rerun setup-gh-cgd. This changes local authentication state and must be done interactively by the user.
• If the identity check succeeds but repository permission is false, grant creative-graphic-design-dev access to the target repository before retrying. Reauthentication is unnecessary when only repository membership changes.
