stax 0.26.0 - Docs.rs

Ship small, reviewable PR stacks quickly without giving up safety.

stax installs both binaries: stax and the short alias st. This README uses st.

Live docs: cesarferreira.github.io/stax
Docs index in this repo: docs/index.md

Why stax

Replace one giant PR with a clean stack of small, focused PRs
Keep shipping while lower-stack PRs are still in review
Navigate the full stack and diffs from an interactive TUI
Restack/merge with transactional safety and fast recovery (st undo, st redo)
Run stack-aware merge/cascade workflows with CI/readiness checks
Generate PR bodies and standup summaries with your preferred AI agent
Work across multiple worktrees, including parallel AI-agent workflows

Install

# Homebrew (macOS/Linux)
brew install cesarferreira/tap/stax

# Or cargo-binstall
cargo binstall stax

Verify install:

st --version

60-Second Quick Start

Set up GitHub auth first (required for PR creation, CI checks, and review metadata).

# Option A (recommended): import GitHub CLI auth
gh auth login
st auth --from-gh

# Option B: enter token interactively
st auth

# Option C: env var
export STAX_GITHUB_TOKEN="ghp_xxxx"

By default, stax does not use ambient GITHUB_TOKEN unless you opt in with auth.allow_github_token_env = true.

# 1. Create stacked branches
st create auth-api
st create auth-ui

# 2. Inspect stack
st ls
# ◉  auth-ui 1↑
# ○  auth-api 1↑
# ○  main

# 3. Submit PRs for whole stack
st ss

# 4. Sync trunk and restack after merges
st rs --restack

Result: two stacked branches, submitted as two linked PRs, then kept up to date with one sync/restack command.

Key Capabilities

Cascade Stack Merge

Merge from stack bottom up to your current branch with safety checks for CI/readiness.

# Merge from bottom -> current branch
st merge

# Wait for readiness explicitly before merging
st merge --when-ready

# Merge full stack regardless of current position
st merge --all

Safe History Rewriting (Undo/Redo)

stax snapshots branch state before destructive operations (restack, submit, reorder) so recovery is immediate when something goes wrong.

st restack
st undo
st redo

Interactive TUI

Launch with no arguments to browse stacks, inspect diffs, and run common operations without leaving the terminal.

st

Agent Worktrees

Run multiple AI/dev agents in isolated Git worktrees while preserving stack metadata and restack flows.

# Create isolated worktrees for parallel tasks
st agent create "Add dark mode" --open-codex
st agent create "Fix auth refresh" --open

# Keep all agent branches rebased when trunk moves
st agent sync

# View and clean up
st agent list
st agent remove add-dark-mode --delete-branch

AI PR Body + Standup Summary

Use your configured AI agent to draft PR bodies and generate daily standup summaries.

# Generate/update PR body from branch diff + context
st generate --pr-body

# Spoken-style standup summary
st standup --summary
