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-cli

This file provides guidance to AI coding agents working with this repository.

## What is hey-cli?

hey-cli is a CLI and TUI interface for [HEY](https://hey.com). 
It allows users to read and send emails, manage their boxes, manage their calendars and journal entries.
The TUI is primarily intended for human use, while the CLI is primarily intended for use by AI agents and for scripting.

## Development commands

This project uses make. `make help` covers most targets -- though not all of them:
`install`, `check-toolchain` and `help` itself are defined but unlisted.

```bash
make build   # Builds ./bin/hey
make test    # Runs the tests
make lint    # Lints the code
make install # Installs the binary to /usr/local/bin/hey (not shown by make help)
```

## Git

History is linear: merge commits are disallowed in this repository. Bring a branch up to
date by rebasing it onto main, never by merging main into it.

## Architecture Overview

This is a Go project that uses:
- [spf13/cobra](https://github.com/spf13/cobra) for the CLI interface
…

How to install

The exact contents, by fingerprint
mdr add basecamp/hey-cli/AGENTS.md@sha256:4042e9ce250b1309

The line at the top of this page pins the label git:20261018.22e0430, 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.
