GitHub CLI (gh) auth — unset stale token env vars before API calls.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GitHub CLI authentication
Before any `gh` command (`gh pr create`, `gh issue`, `gh run`, etc.), **unset stale token environment variables** that override the keyring login:
```bash
env -u GH_TOKEN -u GITHUB_TOKEN gh <subcommand> ...
```
## Why
An invalid or expired `GH_TOKEN` / `GITHUB_TOKEN` in the shell environment causes `HTTP 401: Bad credentials` even when `gh auth status` shows a valid keyring account (with "Active account: false" on the keyring entry).
## Checklist for PRs
1. Push branch: `git push -u origin HEAD` (SSH/git creds are separate from `gh`).
2. Create PR: `env -u GH_TOKEN -u GITHUB_TOKEN gh pr create ...`
3. If auth still fails: `gh auth status` then `gh auth login` if needed.
Do **not** export `GH_TOKEN` for local `gh` unless intentionally using that token for the session.
The line at the top of this page pins the label git:20260603.0f2037c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
