+# auth-rotation-reminder
+
+Claude Code `Stop` hook that periodically logs you out of authenticated
+CLIs (npm, pnpm, gcloud, vault, aws sso, docker, socket, …) so stale
+long-lived tokens don't sit in your dotfiles or keychain for days.
+
+## Why
+
+Long-lived auth tokens live in well-known locations: `~/.npmrc`,
+`~/.config/gh/hosts.yml`, `~/.config/gcloud/`, `~/.docker/config.json`.
+A compromised dev workstation has a wide blast radius on those files.
+Periodic auto-revocation tightens the window and forces explicit
+re-authentication, which is itself a small phishing-defense moment
+("did I really mean to publish?").
+
+## Defaults
+
+- **Interval**: 1 hour. Set `SOCKET_AUTH_ROTATION_INTERVAL_HOURS=4` to
+  loosen, `=0` to run on every Stop event.
+- **Mode**: auto-logout (the hook *acts*, not just warns).
+- **Default skip-list**: `gh` is skipped because Claude Code itself
+  uses `gh` for `gh pr edit` etc. — auto-revoking it would break the
+  agent.
+- **CI**: hook short-circuits when `CI` env var is set.
+
+## What's swept
+
+| id        | display name      | detect            | logout                         |
+| --------- | ----------------- | ----------------- | ------------------------------ |
+| npm       | npm               | `npm whoami`      | `npm logout`                   |
+| pnpm      | pnpm              | `pnpm whoami`     | `pnpm logout`                  |
+| yarn      | yarn              | `yarn --version`  | `yarn npm logout`              |
+| gcloud    | gcloud            | `gcloud auth list ... ACTIVE` | `gcloud auth revoke --all --quiet` |
+| aws-sso   | aws (sso)         | `aws sts get-caller-identity` | `aws sso logout` |
+| gh        | gh (GitHub CLI)   | `gh auth status`  | `gh auth logout --hostname github.com` |
+| vault     | vault             | `vault token lookup` | `vault token revoke -self` |
+| docker    | docker            | `docker info \| grep Username:` | `docker logout` |
+| socket    | socket            | `socket whoami`   | `socket logout`                |
+
+The hook never reads, prints, or compares any token value. Detection
+is exit-code only; logout commands' output is suppressed except for
+non-zero exit codes which surface as "logout failed" lines.
+
+## Snoozing
+
+Need to keep your auth alive for the next few hours (e.g. mid-publish)?
+Drop a `.snooze` file with an ISO 8601 expiry on line 1.
+
+```bash
+# Snooze for 4 hours, project-local
+date -ud "+4 hours" +"%Y-%m-%dT%H:%M:%SZ" > .claude/auth-rotation.snooze
+
+# Snooze globally for 8 hours (applies to every repo)
+mkdir -p ~/.claude/hooks/auth-rotation
+date -ud "+8 hours" +"%Y-%m-%dT%H:%M:%SZ" > ~/.claude/hooks/auth-rotation/snooze
+```
+
+The hook **automatically deletes the file** once the timestamp is
+reached. No manual cleanup needed.
+
+Snoozes that are malformed, empty, or unreadable are also auto-deleted
+on the next run — fail-safe so a corrupted file can't permanently
+disable rotation.
+
+`.claude/*.snooze` is gitignored; project-local snoozes never leak into
+commits.
+
+## Skip-list
+
+Permanently skip a service:
+
+```bash
+# Per-user: applies to every repo
+mkdir -p ~/.claude/hooks/auth-rotation
+echo gcloud >> ~/.claude/hooks/auth-rotation/services-skip
+
+# Per-repo: applies just to this checkout
+echo vault >> .claude/auth-rotation.services-skip
+```
+
+One id per line. Lines starting with `#` are comments. Service ids
+are stable — see the table above.
+
+## Disable temporarily
+
+```bash
+SOCKET_AUTH_ROTATION_DISABLED=1   # any non-empty value
+```
+
+For pairing sessions, demos, etc. The hook short-circuits before
+doing any work.
+
+## Wiring
+
+In `.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "Stop": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "node .claude/hooks/auth-rotation-reminder/index.mts"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Tests
+
+```bash
+cd .claude/hooks/auth-rotation-reminder
+node --test test/*.test.mts
+```
+
+## Reusing the snooze convention
+
+Other hooks can adopt the same `.snooze` pattern. The convention is:
+
+- Filename: `.claude/<hook-id>.snooze` (project) or
+  `~/.claude/hooks/<hook-id>/snooze` (global).
+- Format: ISO 8601 expiry on line 1. Optional further lines ignored.
+- `.gitignore`: `.claude/*.snooze`.
+- Cleanup: hook auto-deletes expired files via `safeDelete`.
+- The `checkSnoozes` / `tryUnlink` helpers in `index.mts` are easy to
+  copy into a sibling hook.
