rt: repo tools

rt is a developer CLI for git-worktree-based monorepo workflows: worktree navigation, smart git rebase/reset, a live MR status dashboard, port scanning, and StrongDM connections, all backed by a background daemon. It ships alongside a macOS menu bar tray app for daemon health and notifications, a VS Code/Cursor extension that shows your branch and linked ticket in the status bar, and a plugin system for adding your own commands that can never crash rt itself.

Full documentation: https://rt.cool

Install

Download mattstack-<version>.dmg from GitHub Releases, drag mattstack.app to Applications, and open it. The app walks you through setup and installs rt, the editor extension, the daemon, and shell integration.

rt is not a separate download: it ships inside the bundle at Contents/MacOS/rt and gets linked onto your PATH during setup. Updates come through the app (Sparkle), not by fetching a tarball.

To drive the same install from a terminal — a fresh machine, a VM, CI:

/Applications/mattstack.app/Contents/MacOS/rt --post-install
rt verify                  # reports the health of each piece

rt verify runs setup on first use and then reports the health of each piece: use it any time you want to confirm the install is in good shape.

Then configure your API tokens:

rt settings linear token   # Linear API key (for ticket lookup)
rt settings gitlab token   # GitLab PAT (for MR status)

For detailed diagnostics:

rt verify

What Gets Installed

Component	Description
`rt` binary	Ships inside mattstack.app (`Contents/MacOS/rt`), linked onto your PATH
`mattstack.app`	Menu bar app: daemon health, notifications, auto-updates
`rt-context` extension	VS Code/Cursor: branch + ticket in status bar
Background daemon	Caches MR/branch data, scans ports, guards git hooks
Bundled helpers	`fzf`, `jq`, `gh`, `glab`, `bun`, `node`, `fast-browser` — pinned and shipped inside the app, not installed onto your system
Shell alias	`rtcd`: fast worktree directory switching

Upgrade

rt update

mattstack.app owns the whole upgrade lifecycle through Sparkle: signature verification, staged install, restart. rt update asks the app to check — it never downloads or installs anything itself, and points you at the latest release if the app isn't running.

Highlights

Worktree-first navigation: rt cd and the rtcd shell alias are a fuzzy picker across every repo and worktree on disk.
Smart git operations: rt git rebase auto-resolves what it safely can onto origin/master; rt sync rebases and pushes the current worktree in one step.
Live MR dashboard: rt status shows pipeline and review status with inline MR actions, backed by a background daemon that keeps GitLab data warm.
Zero-config port scanning: rt port finds and kills processes on stale dev ports without any setup.
macOS menu bar app: mattstack.app shows daemon health at a glance and delivers native notifications.
Editor status bar: the rt-context VS Code/Cursor extension shows your worktree, branch, and linked Linear ticket.
Safe plugin system: drop a folder under ~/.rt/plugins/ to add your own commands; a broken plugin is skipped with a warning and can never crash rt itself.
StrongDM integration: rt sdm connect reads your real StrongDM catalog and connects with friendly names, no maintained list required.

Onboarding a repo

There's no explicit "add repo" step: any git repo with an origin remote is picked up automatically the first time you run an rt command inside it:

cd ~/code/my-repo
rt status            # or rt cd, anything repo-aware

On first invocation rt will:

Derive the repo name from git remote get-url origin
Register the repo in ~/.rt/repos.json
Create a data dir at ~/.rt/<repo-name>/
Start the daemon watching it for MR / branch / port state

If the daemon was already running, the next refresh cycle picks it up (MR data refreshes every 5 min, port scans every ~30s). From then on rt status, rt run, ticket lookup, port scanning, and MR notifications all work from anywhere on your machine.

Optional per-repo config

Command	When you need it
`rt hooks`	Repo uses husky and you want a quick on/off toggle
`rt settings extension`	Install the `rt-context` status-bar extension into local editors

Global settings that affect every repo

Set these once; they apply to all repos:

rt settings gitlab token       # required for rt status, MR actions, notifications
rt settings linear token       # required for ticket lookup in rt status
rt settings linear team        # Set default Linear team
rt settings notifications      # pick which events fire native macOS notifications

Commands

Run rt with no arguments for an interactive menu. All commands support direct invocation:

rt <command> [subcommand] [args]

Navigation

rt cd                     # Fuzzy worktree/repo directory picker

In rt nav, ctrl-o opens the selected folder in your preferred editor.

Shell alias added by install:

rtcd                      # cd into a picked worktree (wraps rt cd)

Run

rt run                    # Interactive script runner: repo → worktree → package → script

Git

rt git rebase             # Smart rebase onto origin/master with auto-resolve
rt git rebase onto        # Rebase onto a specific branch
rt git reset origin       # Sync with origin after a remote rebase
rt git reset soft         # Soft reset to HEAD (unstage files)
rt git reset hard         # Hard reset to HEAD (discard all changes)
rt git commit             # Interactive staging + commit with live diff preview
rt git backup             # Back up current branch to a backup ref
rt git restore            # Restore from a backup branch

Sync

rt sync                   # Rebase current worktree onto master + push
rt sync all               # Sync all worktrees in the repo

Status

rt status                 # Live branch dashboard: MR actions, pipeline & review status
rt port                   # Port scanner + killer (daemon-powered, zero-config)

Daemon

The daemon runs in the background, caching MR data, scanning ports, and guarding git hooks.

rt daemon install         # Install and start the daemon (launchd or background process)
rt daemon uninstall       # Stop and remove the daemon
rt daemon start           # Start the daemon
rt daemon stop            # Stop the daemon
rt daemon restart         # Restart the daemon
rt daemon status          # Show daemon status (pid, uptime, repos, ports)
rt daemon logs            # Tail daemon log

Home repo

~/.mattstack/user is a personal git repo, provisioned by rt home init. While the daemon is running, it watches that repo and auto-commits (and pushes) everything in it except paths inside a claimed zone — you never run git add/git commit there yourself for ordinary changes.

rt home init does three things in order, every time it runs (idempotent — safe on a fresh machine or an already-provisioned one): clone/provision the user/ repo and this machine's user/local/<key>/ profile (picking one interactively on a fresh, keyless machine, or via --profile/--new-profile); ensure the age key exists and .sops.yaml matches it; then materialize — regenerate everything re-derivable from settings, as its last phase. That's rt's own PATH shims (rt intercept install) and daemon registration (rt daemon install, only when not already installed), then each locally-installed tool's own setup verb (deck setup when deck is on PATH and NOT already healthy — deck setup re-bootstraps deck under launchd, restarting the live proxy and blipping every *.localhost app, so an already-healthy deck is reported as skipped instead of re-run). A tracked repo (rt.repoTracking) not present on disk is reported by name, never cloned. mr-board's setup is interactive (GitLab token, Slack OAuth) — materialize only prints the command to run by hand, never runs it. A missing tool is silently skipped, not a failure; only an rt-owned step failing exits rt home init non-zero. Pass --no-materialize to skip this phase entirely. Separately, if claude.marketplaces/claude.plugins resolve to a value, rt home init prints a pointer to the mattstack installer, which owns replaying them — init never does that itself.

rt home init                                        # Provision this machine's ~/.mattstack tree (+ materialize)
rt home init --no-materialize                       # Provision only — skip the last (materialize) phase
rt home init --profile <key> [--new-profile]        # Fresh/keyless machine: adopt (or start) a machine profile without the interactive picker
rt home snapshot                                    # Run the auto-commit cycle right now (reason: manual)
rt home snapshot --status                           # Show daemon state: enabled, last run/commit, push state, claimed zones
rt home claim <zone> [--owner] [--note] [--force]    # Tell the daemon to stop auto-committing a path
rt home release <zone>                               # Let the daemon resume auto-committing a path
rt home key export                                   # Print the age private key once, for your password manager
rt home key import [--stdin] [--force]               # Bring an external age key into the keychain

A zone is a path relative to ~/.mattstack/user, and is either a directory (claims everything under it) or a single file (claims exactly that path and nothing else). Via rt home claim, either prefs/ or just prefs works for a directory — it stats the real path and decides for you, no trailing slash required. Hand-editing snapshot-owners.jsonc directly is stricter: the trailing slash IS the marker there, so write "prefs/" for a directory and "scripts/deploy.sh" (no slash) for a file — a bare "prefs" with no slash is read back as a file zone named literally prefs, not a directory. release works either way without needing to guess. Claim a zone when you're mid-edit on something and don't want the daemon committing a half-finished state out from under you — --owner defaults to <you>@<machine-key>, and --note is a free-text reason anyone reading the owners file can see. Claiming a zone someone else already owns refuses (naming them) unless you pass --force. Claiming and releasing write user/snapshot-owners.jsonc directly (no daemon round trip); the daemon then snapshots that file itself, like any other change.

A claimed zone left dirty past a threshold is still committed — the janitor rule — under its own snapshot (janitor): … message, so an abandoned claim can't block the zone from ever being backed up. The daemon's behavior is configured by the rt.homeSnapshot settings key (machine-scoped):

{
  "enabled": true,             // false disables watching and auto-commits entirely
  "debounceSec": 20,           // quiet period after a change before committing
  "pushDelaySec": 60,          // coalescing delay before pushing a commit
  "janitorThresholdHours": 6,  // a claimed zone dirty this long gets janitor-committed
  "janitorIntervalMin": 30     // how often the janitor sweep runs
}

Flipping enabled to false is a kill switch: the daemon stops committing AND cancels any already-scheduled push (including a pending retry) on its very next cycle — nothing new reaches origin while it's off, though a commit already pushed stays pushed. Re-enabling picks a pending push back up on the next run.

rt home snapshot (manual) reuses an already-in-flight run instead of queuing its own: if it lands while the watcher is mid-cycle, it returns THAT run's result — which can report reason: "watch" and skip janitor zones (gated to "janitor"/"manual") even though you asked for a manual run. Run it again for a fresh manual cycle.

User plugins

Add your own commands to rt. A plugin is a folder under ~/.rt/plugins/<name>/ with a plugin.json manifest and TypeScript files (or existing executables). Plugin commands get rt's navigation, repo/worktree context resolution, arg forms, and logging for free, and a broken plugin can never break rt itself.

rt plugin new my-tool     # scaffold + IDE types (autocomplete on ctx.rt.*)
rt my-tool                # run it: edit ~/.rt/plugins/my-tool/my-tool.ts and rerun
rt plugin list            # see installed plugins and their health
rt plugin validate        # deep checks: files exist, modules import, exports match

A command is TypeScript ("module": "./my-tool.ts", gets the injected ctx.rt API: pick/prompt/confirm, scoped storage, logging) or any executable ("exec": "./scripts/deploy.sh", gets RT_* env vars). Commands merge into the root tree; name collisions are flagged and built-ins always win. Notes:

Runtime contract: standard library + injected API only (no npm deps in v1).
Plugin code runs in-process with rt's privileges. Only install plugin directories you trust; reading a third-party plugin before installing it is reading the code you are about to run.
apiVersion: 1 is required in every manifest.

StrongDM

rt sdm is a StrongDM auth-and-connect module: it logs you in, lists the datasources you can reach, and connects you fast with friendly names.

rt sdm connect            # pick a datasource and connect (auto-logs-in if your session expired)
rt sdm status             # StrongDM auth health + connected tunnels
rt sdm login              # log in (browser popup, terminal fallback)
rt sdm set-email <email>  # set the email rt logs in with
rt sdm refresh            # re-scan the catalog
rt sdm enrichment [init]  # show or scaffold the enrichment map

rt reads your resources straight from the StrongDM CLI (sdm access catalog + sdm status), so there is nothing to configure and no list to maintain. Every real datasource you can reach shows up in the picker. If rt sdm connect only shows recents, your session expired; it logs you back in automatically before listing.

Enrichment (optional, declarative)

Raw StrongDM names (example-alpha-staging) work as-is, but you can give them nicer labels, group them by tier, and set connect defaults with a declarative file you own at ~/.rt/sdm/enrichment.jsonc. Nothing runs to enrich; rt just reads this JSON and overlays it on the live catalog.

Scaffold it from your current catalog, then fill in the labels:

rt sdm enrichment init    # writes ~/.rt/sdm/enrichment.jsonc: every resource, blank labels
rt sdm enrichment         # show the file path + how many resources are enriched vs raw

{
  // map a StrongDM resource name to a nicer label + connect metadata
  "example-alpha-staging": { "label": "alpha staging", "tier": "staging",    "db": { "schema": "public" } },
  "example-alpha-prod":    { "label": "alpha prod",    "tier": "production", "production": true }
}

field	meaning
`label`	shown in the picker (defaults to the raw resource name)
`tier`	`development` / `qa` / `staging` / `production` / anything: groups the picker
`production`	`true` adds a confirm guard before connecting
`reasonSuggestion`	prefill for the access-request reason prompt
`db`	`{ database, schema, user }` hints used to verify the tunnel after connecting

A resource missing from the file just shows its raw name and connects with Postgres defaults. Keep the file in your own repo and copy or symlink it to ~/.rt/sdm/enrichment.jsonc to share it with your team.

RT Context Extension

The rt-context VS Code/Cursor extension shows your current worktree, branch, and linked Linear ticket in the status bar. The installer (rt --post-install) installs it into every detected editor.

To reinstall or install into additional editors:

rt settings extension

This opens a fuzzy picker to select which editors (Cursor, VS Code, Antigravity, etc.) to install into.

Status Bar

📁 main-worktree  │  🔖 ACME-1287: Add damage photo uploads

Clicking the item opens the linked Linear ticket directly.

RT Tray App

The rt-tray menu bar app shows daemon health and delivers native notifications.

Green dot: daemon running normally
Yellow dot: daemon starting
Orange dot: pending notifications
Red dot: daemon not reachable

From the menu you can restart the daemon, stop it, toggle launch-at-login, and check for updates.

Requirements

Dependency	Notes
macOS	Required (Apple Silicon or Intel)
`fzf`	0.71.0 or newer (`--listen` and `--id-nth`, used by `rt nav`'s live refresh); `brew install fzf`
`tmux`	`brew install tmux`
`chafa`	Optional, renders image previews in `rt nav` as colored character art (`brew install chafa`)
`kitten`	Optional, upgrades `rt nav` image previews to true pixels on Kitty-protocol terminals such as Ghostty. Ships with Kitty (`brew install --cask kitty`)

Development

This repo uses Bun.

Day-to-day dev (source mode)

The normal way to develop: no compile step, changes are instant.

git clone https://github.com/m4ttstack/rt.git
cd rt
bun install
bun run cli.ts          # runs the CLI from source
bun run cli.ts verify   # run any subcommand the same way

rt --version will report dev when running from source.

Switching between dev and production

Once mattstack.app is installed alongside your source checkout, use the built-in toggle:

rt settings dev-mode        # interactive picker: dev ↔ prod
rt settings dev-mode dev    # switch to local source
rt settings dev-mode prod   # switch back to the installed binary

How it works:

dev mode writes a wrapper script at ~/.local/bin/rt that calls bun run /path/to/cli.ts "$@" and hands the tray over to mattstack-dev.app
prod mode installs the compiled binary carried inside mattstack.app at that same path and hands the tray back to mattstack.app
~/.local/bin is added to your PATH automatically (in your shell rc file) by the installer and on first dev-mode dev
The source path is remembered in ~/.mattstack/rt/state.db (a kv row, ns dev-mode), so there's no re-entry needed when toggling back

rt version tells you which is active (and the source path in dev mode); rt --version is the short form that just prints the version string.

Testing the installer

Run the post-install script manually to test the full setup flow on your machine:

rt --post-install

This is the same code that rt auto-runs on its first invocation (and that rt update runs from the freshly downloaded release). Run from an extracted release tarball it:

Installs the rt binary at ~/.local/bin/rt
Copies mattstack.app to ~/Applications
Installs rt-context.vsix into all detected editors
Installs the daemon as a launchd agent
Writes shell integration to your rc file (PATH + rtcd, idempotent, supports zsh, bash, fish)

Verifying an installation

rt verify           # human output, exits 1 on critical failures
rt verify --ci      # same output, no ANSI colors (for CI logs)
rt verify --json    # structured JSON for tooling

Critical checks: binary on PATH, fzf, tray app, vsix, daemon installed + running + API responding.

Building a local compiled binary

Use this to test how the release binary behaves (compiled mode, no bun dependency):

bun build --compile ./cli.ts --outfile /tmp/rt-local
/tmp/rt-local --version
/tmp/rt-local verify

rt-context extension

cd extensions/vscode/rt-context
bun install
bun run watch       # live rebuild during development

# Package a .vsix manually
bun run package     # outputs rt-context-x.x.x.vsix

# Install into local editors
bun run install-local   # packages + installs into Cursor
# or via the CLI:
rt settings extension

rt-tray

cd rt-tray
./build.sh debug    # build and open in Xcode simulator
./build.sh release  # build release mattstack.app (prod)
./build.sh dev      # build release mattstack-dev.app (dev, runs the daemon from source)
./build.sh install  # build + copy mattstack.app to ~/Applications

The tray app reads its version from Info.plist (CFBundleShortVersionString), which the CI build injects via git describe. Local builds report the version as whatever is in the plist at build time.

Release process

Push a version tag; CI handles everything else:

git tag v1.2.3
git push --tags

GitHub Actions will:

Compile rt for arm64 + x64
Build mattstack.app with version baked into Info.plist
Package rt-context.vsix
Create a GitHub Release with bundled tarballs
Install from the published tarball on a fresh macos-latest runner and run rt verify --ci

Setup lives in the binary itself: cli.ts detects a missing ~/.mattstack/rt/daemon.json on first invocation and transparently runs commands/post-install.ts, which is also what rt --post-install and rt update invoke.
