A local command-line tool for managing stacked pull requests in repositories that merge by squashing commits. A stacked pull request is a chain where each branch builds on the previous one.

Inspecting, tracking, synchronizing, merging, documenting, and undoing stacked pull-request workflows.

It preserves the intended branch and pull-request relationships even after squash merges remove normal Git ancestry. Its undo data can restore branch tips and stack metadata after changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00061	$0.02114
Opus 5.5	$0.00024	$0.00846
Sonnet 5.5	$0.00012	$0.00423

Security

Grade A, and why

stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to stack — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stack

Use the local stack CLI for squash-safe stacked PR repair. It is designed for repos where PRs are squash-merged and merged branches are deleted, so Git ancestry alone cannot preserve stack intent.

Keep ordinary editing and commits on plain git. Use stack only for stack intent, stack inspection, sync, merge, and undo workflows.

Mental Model

dev
└─ stack-a  #101
   └─ stack-b  #102
      └─ stack-c  #103

Stack intent is persisted in .git/stack/state.json as stack links:

branch
parent branch
merge-base anchor
PR number

Mutating sync and merge workflows write .git/stack/undo.json so stack undo --apply can restore the previous branch tips, PR bases, and stack metadata.

Common Commands

stack status: show the relevant tracked stack graph and include open PR details when GitHub is available.
stack guide: print the opinionated happy path for agents and humans.
stack track <branch> --onto <parent>: record stack intent for an existing branch.
stack sync --dry-run [branch]: preview inferred PR-base stack links and repairs without changing branches or PRs.
stack sync [branch]: infer clear PR-base stack links, repair descendants, retarget PRs, and refresh stack blocks. With a branch argument, sync only the stack containing that branch.
stack sync --continue-on-failure / stack sync --keep-going: process independent stacks, summarize successes and failures, and exit nonzero if any stack failed.
stack doctor: inspect local Git, GitHub, stack metadata, trunk branches, and undo journal health without changing anything.
stack merge [branch]: dry-run root PR merge plus descendant repair.
stack merge [branch] --apply: retarget immediate child PRs, squash-merge the root PR, then repair descendants.
stack merge [branch] --auto: retarget immediate child PRs, enable GitHub auto-merge, wait, then repair descendants.
stack merge --auto --through <branch-or-pr>: repeat auto-merge one root at a time until the target branch or PR lands.
stack history: show the most recent applied repair journal.
stack undo: dry-run restore of the most recent applied repair.
stack undo --apply: restore branches, PR bases, and stack metadata from the journal.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
