hey from basecamp/hey-cli is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add basecamp/hey-cli/hey@git:20261027.bcf2799

Pins git:20261027.bcf2799 in mdr.lock. Pin the fingerprint instead.

Interact with HEY via the HEY CLI. Read and send emails, manage contacts, boxes, labels, collections, calendars, todos, habits, time tracking, and journal entries. Use for ANY HEY-related question or action.

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

# /hey - HEY Email Workflow Command

CLI for HEY: mailboxes, labels, collections, email threads, contacts, replies, compose, calendars, todos, habits, time tracking, and journal entries.

Use the installed CLI as the command reference. This skill holds the rules that span commands; it does not copy the command catalog, because the binary's own help is the source of truth and always matches the version you are running.

## Discovery-first workflow

For each task:

1. Infer the deepest plausible leaf command from the user's words.
2. Unless its arguments and flags are already established by a tool result in this conversation, read that leaf's help before running it:

   ```bash
   hey <group> <subcommand> --agent --help
   ```

3. If the leaf does not exist, read its nearest parent group. Use root help only when the top-level group itself is unclear:

   ```bash
   hey <group> --agent --help   # fallback
   hey --agent --help           # last resort
   hey commands --json          # every command with its agent_notes
   ```

4. Treat the leaf's `short`, `long`, `agent_notes` and `flags` as the source of truth. Do not guess positional arguments, flags, accepted values, or limits.
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add basecamp/hey-cli/hey@sha256:fcbe74807b98d13b

The line at the top of this page pins the label git:20261027.bcf2799, 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.
