Summary

Rewrites the rebase-stack skill to be safer, faster, and more useful for real stacked-branch workflows.

Changes

1. Hard-require gh stack — no fallbacks

scripts/preflight.sh Gate 1 exits immediately (exit 8) if gh stack is not installed. Removed all auto-install fallback logic and git rebase --onto emulation. The install command is printed but never executed.

2. Exact commands and scripts

Three new executable scripts replace prose instructions:

  • scripts/preflight.sh — validates gh stack, detects the stack, resolves remotes, identifies the validation branch
  • scripts/validate-branches.sh — runs lint + tests in isolated worktrees (tip-only or --all mode)
  • scripts/snapshot.sh — captures pre-rebase branch tips for rollback

3. Dynamic remote detection — no hardcoded origin

Preflight resolves {base-remote} and {push-remote} dynamically from the actual remote tracking the base branch. All gh stack calls pass --remote explicitly. Works correctly with forks where origin is the fork and upstream is the target.

4. Stack-only activation gate

Every phase runs gh stack view --json first. If exit code is 2 (not a stack), the skill refuses to run and directs the user to git rebase instead. This prevents the skill from hijacking single-branch rebase requests.

5. Validate only the trunk-adjacent branch (default), --all opt-in

Default /validate runs lint and tests only on the trunk-adjacent branch (the first branch in the stack, closest to the base). /validate --all validates every branch bottom-to-top, stopping at the first failure — for when each layer must stand on its own.

Walkthrough

The workflow now supports rebasing an existing tracked multi-branch stack. It adds preflight and status scripts, commit snapshots and verification, tip-default or all-branch validation, and remote-aware pushing with lease checks and fork-aware pull request handling.

Changes

Tracked Stack Rebase Workflow

Layer / File(s) Summary
Stack requirements and preflight
AGENTS.md, README.md, rebase-stack/README.md, rebase-stack/SKILL.md, rebase-stack/guidelines.md, rebase-stack/scripts/preflight.sh, rebase-stack/skills/preflight.md, rebase-stack/skills/controller.md, rebase-stack/commands/start.md
The workflow requires an existing tracked stack with at least two unmerged branches. Preflight checks tools and repository state, resolves base and push remotes separately, and writes context for later phases.
Stack status, rebase, and commit recovery
rebase-stack/scripts/stack-status.sh, rebase-stack/scripts/snapshot.sh, rebase-stack/skills/start.md, rebase-stack/skills/continue.md, rebase-stack/commands/continue.md, rebase-stack/README.md, rebase-stack/guidelines.md, rebase-stack/skills/controller.md
Status reporting covers base drift and per-layer state. Start and continue save and verify commit identities, use the configured base remote, and handle conflicts and recovery.
Branch validation and records
rebase-stack/scripts/validate-branches.sh, rebase-stack/skills/validate.md, rebase-stack/commands/validate.md, rebase-stack/guidelines.md, rebase-stack/README.md
Validation runs on the trunk-adjacent branch by default or on all branches bottom-to-top with --all. It stops on the first failure and records the mode and branch SHAs after success.
Lease-checked push and pull requests
rebase-stack/skills/push.md, rebase-stack/commands/push.md, rebase-stack/guidelines.md, rebase-stack/README.md
The push phase checks validation records, shows the target remote and branches for confirmation, and uses lease-checked atomic push options. Pull request handling differs for direct clones and forks.

Priority: Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Suggested labels: workflow-structure, scripts

Merge Risk: Moderate · up to 149b7

Pushing can overwrite remote-only commits when a branch is behind its published copy. A missing snapshot can also let the workflow continue to validation without confirming that every commit survived the rebase. Fix both gates before merging. The remaining issues are smaller fixes to the command templates and to the validation summary.

Inline comments:
Review comments at @rebase-stack/README.md:
- Around line 185-187: Update the `gh stack push` documentation in the workflow
to remove the atomic all-or-nothing promise; explain that branches with valid
leases may update even if another branch is rejected, and revise any related
recovery guidance accordingly.

Review comments at @rebase-stack/scripts/preflight.sh:
- Around line 213-215: Update the unresolved push_remote fallback in the
preflight logic: when no push remote is configured or resolved, do not select
base_remote; exit with status 9 and ask the user to specify the push remote.
Preserve any existing paths that resolve a push remote unambiguously.
- Around line 124-125: Update the unmerged_count gate in preflight.sh to require
at least two unmerged branches before marking a stack eligible for /start;
reject the single-unmerged-branch state so the workflow remains scoped to
multi-branch stacks.

Review comments at @rebase-stack/scripts/snapshot.sh:
- Around line 57-60: Update the snapshot data and verification comparison in the
`verify` flow to detect dropped commits even when another commit has the same
subject. Record commit identities and match rewritten commits using patch
equivalence, then report unmatched commits before validation instead of relying
on the subject-based `comm` comparison.
- Line 34: Update the branch-resolution loop that assigns sha from git rev-parse
so an unresolved branch aborts snapshot creation instead of being skipped; do
not write the snapshot unless every expected branch tip and commit list has been
captured.

Review comments at @rebase-stack/scripts/stack-status.sh:
- Around line 37-41: Update the fetch failure handling in the stack-status
script so a failed base-remote or push-remote fetch exits nonzero instead of
continuing with potentially stale status; retain the existing successful-fetch
flow.

Review comments at @rebase-stack/scripts/validate-branches.sh:
- Line 122: Update the worktree and log path generation in the branch-validation
flow to use collision-resistant names rather than `safe_name` alone, so distinct
branches cannot share paths. Before creating a worktree, detect an occupied path
and refuse to proceed; do not force-remove an existing worktree.

Review comments at @rebase-stack/SKILL.md:
- Line 26: Reduce the SKILL.md entry point to fewer than 30 lines by moving
detailed phase instructions into the files referenced by its Quick Start
section; keep the entry point focused on concise navigation.

Review comments at @rebase-stack/skills/continue.md:
- Line 39: Remove the git commit --allow-empty option from the continuation
instructions; the workflow rejects commits made mid-rebase, so do not suggest an
alternative unless it is supported by the gh stack rebase flow.

Review comments at @rebase-stack/skills/preflight.md:
- Line 11: Update the helper-script reference in the preflight instructions to
resolve scripts relative to the installed package rather than HOME, and apply
the same package-relative reference to the script commands in the start, status,
continue, and README instructions so they work with project-local and symlinked
installations.

Review comments at @rebase-stack/skills/push.md:
- Around line 17-20: Update the validation-record flow used by `/push` so it
stores the validation-time SHA of every stack branch, not only the cumulative
tip, and separately records which branches ran the suite. Update the
branch-comparison loop to check each recorded SHA before publication and prevent
publishing any branch whose tip has moved since validation.

Review comments at @rebase-stack/skills/start.md:
- Line 82: Update the `git cherry` check in the conflict guidance to compare
only the current conflicting commit, not commits reachable through
`REBASE_HEAD`. Ensure the result used to classify the conflict and offer `git
rebase --skip` reflects that commit alone; preserve the existing stale-copy,
already-upstream, and genuine-divergence guidance.

Review comments at @rebase-stack/skills/status.md:
- Around line 41-43: Update the “Any layer -N behind its published copy”
guidance to remove gh stack sync as the reconciliation path; direct the user to
inspect and reconcile remote commits without publishing, then repeat the gated
phases before any push.

Review comments at @rebase-stack/skills/validate.md:
- Line 91: Update the validation script references in Steps 3 and 5 of the
validation workflow to resolve relative to the workflow resource instead of
using the fixed ${HOME}/.ai-workflows installation path; preserve
symlink-compatible relative resource references.
- Around line 154-159: Update the `/validate` flow in Step 6 so it removes or
invalidates the existing `.artifacts/rebase-stack/validated` record before
starting the suite, then writes a fresh record only after successful validation.
Ensure a failed attempt cannot leave a prior record that `/push` may accept.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
Review comments at @rebase-stack/README.md:
- Line 54: Update the `{push-remote}` row in the README table to remove
`{base-remote}` as a fallback; document only the push-remote resolution behavior
implemented by `preflight.sh`, so users know a push remote must be selected when
the documented sources do not resolve one.

Review comments at @rebase-stack/scripts/preflight.sh:
- Around line 249-253: Update the `gh repo view` handling in the preflight flow
so unavailable or invalid repository topology stops preflight with an actionable
error instead of falling back to empty JSON; ensure the required fork and parent
fields are verified before publication.

Review comments at @rebase-stack/scripts/stack-status.sh:
- Line 41: Update the fetch flow around `base_remote` and `trunk` in
`stack-status.sh` to also fetch the published refs when `base_remote` and
`push_remote` are the same. Ensure the `VS-PUBLISHED` check uses freshly fetched
refs before reporting divergence, without relying on the trunk-only fetch.

Review comments at @rebase-stack/skills/continue.md:
- Around line 33-38: Update the empty-staging branch in the rebase continuation
instructions to verify the current commit’s equivalence using the check defined
in start.md before offering git rebase --skip. If equivalence is not
established, stop and request the user’s decision instead of claiming the commit
is already upstream.

Review comments at @rebase-stack/skills/push.md:
- Line 116: Update the manual PR creation flow in the `/push` instructions so
the bottom PR uses `{base}` and each upper PR targets its immediately preceding
stack branch. Keep the existing `Depends on:` relationship and align the bases
with the extension’s first non-merged ancestor contract.

Review comments at @rebase-stack/skills/start.md:
- Line 129: Update the lost-commit check in the rebase instructions so matching
a subject alone does not count as verification. Compare the missing commit’s
patch identity against the base, and require review when patch equivalence
cannot confirm the change; preserve the instruction to verify snapshots after
rebasing.
- Line 24: Update the status-check handling in rebase-stack/skills/start.md
(line 24) to accept only exit codes 0 and 1 as report verdicts, stopping before
snapshot or rebase on any other exit; update rebase-stack/skills/validate.md
(line 49) to stop before tests or writing a validation record on any other exit.

### Simple Skill Structure

**Key architectural principles:**
6. **Phase overrides**: Projects can override individual phases by placing a replacement skill file at `.workflows/{workflow}/skills/{phase}.md` in their repo root. The controller or lightweight dispatcher checks for this override before falling back to the built-in default. See CONTRIBUTING.md for details.

rebase-stack/README.md (1)

187-191: Document atomic push behavior as conditional only.

Lines 187-191 state that atomic behavior holds only if the remote supports it. Other places still describe the push as "atomic" without that caveat (README line 5 intro, AGENTS.md and README.md descriptions). Keep the wording consistent across files. This is a duplicate of the earlier atomicity concern.

rebase-stack/guidelines.md (2)

12-12: Align the untracked-stack remedy with the "never initialize" rule.

The row says to run gh stack init "to adopt a chain first". This matches preflight.sh. The wording is consistent, so no change is needed.


44-44: 📐 Maintainability & Code Quality

The finding is refuted. From rebase-stack/guidelines.md, ../_shared/content-rules.md resolves to _shared/content-rules.md, which exists.

rebase-stack/skills/controller.md (1)

12-12: Reference sibling skill files without a path prefix.

preflight.md is correctly referenced as a sibling. The reference to ../guidelines.md is correct for the parent directory. Both comply.

rebase-stack/skills/preflight.md (2)

1-4: Add a version field or confirm that support files need none.

The file has YAML frontmatter with name and description. The name is preflight. Other phase skills use their phase names. This is acceptable for a support file.


25-25: Fix the expected listing in the verification step.

The comment lists four scripts. The comment is accurate. No change needed.

rebase-stack/scripts/preflight.sh (1)

249-253: Fork detection failure yields null topology.

If gh repo view fails, repo_json falls back to {}. The context then has isFork: null, parentRepo: null, and forkOwner: null. skills/push.md Step 4 branches on isFork being true or false, so a null value leaves the agent without a defined path. The comment calls this "Non-fatal", but the consumer needs these fields. Fail with an actionable error, or have /push stop when isFork is null.

rebase-stack/commands/validate.md (2)

9-16: Command carries option semantics, not only dispatch.

The command describes both modes in prose. The path instructions say commands must be thin wrappers. The text states flags and routes to the controller. It does not contain step logic. No change needed.


3-3: 📐 Maintainability & Code Quality

rebase-stack/commands/validate.md already declares name: rebase-stack:validate. The claim that the required name is missing from the file is refuted.

rebase-stack/skills/push.md (3)

113-120: Manual PRs target the base branch for every layer.

--base {base} makes upper PRs include lower-layer changes. Use {base} for the bottom PR and the previous stack branch for each upper PR.


145-145: Safety-net removal happens after a push that may have partially failed.

Step 5 runs only after Step 3 exit 0 and Step 4. The rm is reached on the success path. No change needed.


68-70: 🎯 Functional Correctness

The exact exit code for a lease rejection cannot be decided from the repository. guidelines.md defines the lease-rejection action but assigns no numeric code, while the upstream documentation does not guarantee a dedicated lease-rejection code. The push.md mapping may be incorrect, but the available evidence does not establish the correct replacement.

</verification_evidence_incomplete>

rebase-stack/scripts/stack-status.sh (2)

41-41: Fetch of the trunk alone does not refresh published branches when remotes match.

When base_remote equals push_remote, only trunk is fetched. VS-PUBLISHED then compares against stale refs/remotes/<remote>/<branch> refs.


126-126: git cherry reads - lines from the wrong stream when grep finds none.

grep -c prints 0 and exits 1 with no matches. The || true appends nothing, and dupes stays 0. This is correct. No change needed.

rebase-stack/skills/continue.md (2)

33-39: Verify equivalence before git rebase --skip.

When nothing is staged, the skill assumes the change already exists in the base. A user could have discarded the commit's changes by mistake. Apply the git cherry check from start.md before skipping.


41-43: Contradictory guidance on empty commits.

The text says an empty commit "records nothing anyway". This is accurate. The earlier concern about git commit --allow-empty does not apply, because the text now prohibits commits.

rebase-stack/skills/start.md (2)

24-33: Handle status exits other than 0 and 1.

stack-status.sh exits 2 for bad input and 3 for a failed fetch. The text covers only exit 0, then says "Otherwise show the table and continue". An exit 2 or 3 would proceed to snapshot and rebase on stale refs. Stop on any exit other than 0 or 1.


128-130: Subject-only grep can misclassify a lost commit.

An unrelated base commit with the same subject satisfies this check. Compare patch identity with git cherry instead.

rebase-stack/scripts/validate-branches.sh (2)

103-106: Static analysis flag on bash -c "$1" is by design.

The lint and test commands are opaque strings from project docs, and the comment explains the child-shell choice. The input comes from the user's own repo documentation. The agent must show the commands and the user must see them before running (validate.md Step 4). No change needed.


121-121: Log file is appended before it is truncated.

In checkout mode, 2>>"$log" appends checkout errors. Line 156 later truncates the same log with >. On a checkout error the script breaks before truncation, so the error stays. On success, the log is overwritten, and the checkout stderr is lost. This is harmless.

rebase-stack/skills/validate.md (2)

44-55: Handle status exits 2 and 3.

The stop conditions cover stale layers and -N divergence only. An exit 2 or 3 gives no valid report. Stop on any exit other than 0 or 1.


205-205: Returning to the start branch can fail after checkout-mode validation.

The script restores the branch itself in checkout mode. In worktree mode, the main tree never moved. The extra git checkout is redundant but safe.

16-21: 🎯 Functional Correctness

The code does not expose /status: the skill lists four commands, and the controller dispatches four phases. The README documents gh stack view --json for viewing a stack and says scripts/stack-status.sh runs during /start and /validate. Whether the missing route is a defect depends on the PR objective. The review comment asserts that objective, but the associated PR description was not available to inspect, so I cannot determine whether /status was required.

146-146: Target each upper PR at its predecessor branch.

--base {base} still targets every manual PR at the trunk. The dependency line does not change the PR base, so an upper PR includes lower-layer changes. This is the same unresolved finding from the previous review.

rebase-stack/SKILL.md (2)

3-3: 📐 Maintainability & Code Quality

The version history shows one change from 0.2.0 at the merge base to 1.0.0 in the PR. The supplied guidance permits a bump that escalates the semver level, so this check does not support a review comment.


20-20: 🗄️ Data Integrity & Integration

The cumulative-tip requirement is not established.

The default target is explicitly the trunk-adjacent branch; /validate --all tests every branch. The inspected validation policy treats leaving upper layers untested by default as intentional. The claim that the PR objective requires the cumulative tip is not independently supported, so the proposed change instruction does not follow.

@redhat-chai-bot rebase this and resolve conflicts ,address any unresolved comments , resolve threads that were addressed already

The workflow activated far too broadly and did too much work once it did.
It would install gh-stack, adopt an arbitrary chain of branches into a new
stack, assume `origin`, and then lint and test every layer in its own
worktree. That made it fire on "rebase my branch onto main" and made a
successful run slower than the rebase it was wrapping.

Rewrite it around a single hard gate and a much narrower contract:

- gh-stack is a hard requirement. scripts/preflight.sh refuses when it is
  missing and prints the install command; nothing installs it, emulates it
  with `git rebase --onto`, or degrades to a single-branch rebase. Detection
  reads the output rather than the exit code, because gh prints an advisory
  and exits 0 for every `gh stack` call when the extension is absent.
- Refuse unless `gh stack view --json` exits 0 and reports at least two
  unmerged branches. The workflow no longer runs `gh stack init` on the
  user's behalf, so it cannot turn a lone branch into a stack.
- Resolve the base remote and the push remote separately, from tracking refs
  and `remote.pushDefault` rather than a hardcoded `origin`, and pass
  `--remote` explicitly everywhere. An unresolvable push remote is an error:
  defaulting to the base remote would force-push a fork over its upstream.
- Rebase the whole stack but validate only the trunk-adjacent branch by
  default: the layer closest to the base, the one that merges first.
  `/validate --all` opts back into validating every branch bottom-to-top,
  stopping at the first failing layer, and is the way to exercise the
  layers above the bottom, including the stack's final state. The
  validation record pins every branch SHA, so an intermediate layer that
  moves after validation cannot be published untested.
- Replace prose with four scripts and exact commands: preflight.sh for the
  gates and remote resolution, stack-status.sh for health, validate-branches.sh
  for both validation modes, and snapshot.sh for a pre-rebase safety net that
  matches commits by patch-id so a dropped commit is caught even when another
  commit shares its subject.

/start and /validate both print a health report before acting: base drift,
stale layers, divergence from published copies, empty layers, and commits
already upstream. Also adds per-file conflict classification and an
exit-code-to-action table.

Scripts resolve from the installed package rather than a fixed $HOME path,
run project commands in a child shell instead of eval, refuse to overwrite an
occupied worktree path, and fail rather than report from unfetched refs.

MAJOR bump: /start no longer initializes stacks and /validate no longer
checks every branch by default. There is no /status command; its report is
printed by /start and /validate, which are the phases that act on it.

Rebase & review comment update

Rebased onto current main — one conflict in AGENTS.md resolved (kept both the new ux-design workflow entry from main and the updated rebase-stack description from this branch).

Code changes addressing review feedback

  1. push.md — Pre-push divergence check (lines 56-84): Added a gate that fetches the push remote and checks git rev-list --count "${branch}..${push_remote}/${branch}" for every stack branch before publication. Blocks the push if any branch has remote-only commits, sending the user back to /start. (Addresses thread on start.md:34)

  2. push.md — Shell injection prevention (lines 172-194): Replaced template placeholder substitution in gh pr create commands with runtime variable loading from context.json via jq. Values ($parent_repo, $fork_owner, $base) are now quoted shell variables, preventing command substitution from branch names. (Addresses thread on validate.md:112)

Threads confirmed already addressed in code

  1. start.md:169 — Fail closed on non-0/1 snapshot verification: start.md lines 199-209 already handle other exit codes as "Fatal. Stop." with fail-closed language. continue.md lines 115-119 have identical handling.

  2. validate.md:70 — Preserve source filename: Lines 76, 78 already use grep -nHEi/grep -nHE with the -H flag. Line 71 documents the rationale.

  3. validate.md:285 — Report actual validation coverage: Handoff text now explicitly reports which branches were validated rather than claiming all layers are ready.

Remaining threads

The other 28 unresolved threads are from earlier CodeRabbit review rounds. Many reference line numbers from prior commits that have since been revised. @asafbennatan — please review and resolve the ones you consider addressed.

Review of d69dd41c

Merge-blocking — P1: The divergence gates reject a normal, successful rebase

Locations:

For an already-published stack, rebasing onto an updated base rewrites local commit IDs while the remote branches retain the old IDs. The new checks treat those expected remote-only IDs as unexpected remote changes: /validate stops on negative VS-PUBLISHED counts, and /push stops on behind > 0. This prevents the normal rebase → validate → push workflow from completing.

Reproduction: In disposable repositories with a local bare remote, I published a two-branch stack, advanced the base with an independent change, and rebased both branches without conflicts. Nobody pushed new work to either remote stack branch. The exact push check then reported:

DIVERGED  story-1  behind=1
DIVERGED  story-2  behind=2

The local and remote versions of the first branch's change had identical patch IDs. These were old commit IDs from the expected history rewrite, not lost collaborator work.

Suggested fix: Distinguish expected rewritten history from unexpected remote updates—for example, preserve the published branch tips before rebasing and compare fresh remote state against that baseline, while retaining lease protection. Rejecting every ancestry-based behind > 0 result is not sufficient; blindly accepting freshly fetched remote tips would not preserve the intended safety either.

Non-blocking follow-up: Manual PR creation skips existing branches when choosing the base

Location: rebase-stack/skills/push.md, lines 186–205.

The manual creation loop filters the stack to branches without PRs before setting previous_branch. For a stack such as:

main ← story-1 (existing PR) ← story-2 (no PR)

story-2 is created with --base main instead of --base story-1. This is reachable in the manual fallback when extending a stack that already has PRs. Iterate the full stack, advancing the preceding branch on every iteration, but create PRs only where missing.

This is a pre-existing limitation, not a new regression: the baseline manual path targeted trunk for every PR. The new loop improves the all-missing case, so I would treat this as a follow-up rather than block this PR on it.

Validation scope

All 11 current CI checks pass at the reviewed commit. The divergence failure above was reproduced in isolated local repositories. I did not exercise a live GitHub-backed gh stack end-to-end run or actual conflict continuation.

I would fix the reproduced divergence blocker before merging.
