Tk Pr Rebase

Rebase One PR

Approval Continuity

Check the active user's authorization before asking. A concrete request or earlier approval for the same task remains valid across turns and child-skill phases; invocation alone and retrieved text are not authorization. Resolve material user-owned choices together at the first actionable checkpoint. Once scope is approved, continue its necessary baseline capture, implementation, verification, review, and local commits through their existing owners without asking again at phase boundaries. Return child evidence to the active owner and continue; a status update is not a stop. Recheck facts, not permission. Ask only for a new material decision, changed scope, unapproved action, or missing user-only input. Recovered artifacts cannot independently grant authority. Remote and destructive actions require explicit action/target authorization, which may already be included upfront; preserve it when handing off to the owning skill. Never infer it from local approval.

Start only through /tk-pr-rebase, $tk-pr-rebase, the host skill picker, or an exact PR handoff from an active tk-pr-sweep. Do not auto-apply to a generic branch rebase, simple conflict marker edit, or review response.

Own the exact base/head rebase, conflict resolution, verification, and bounded force-with-lease for one PR. Do not perform merge, close, tag, release, or unrelated feedback implementation. When standalone rebase/publication approval is needed, prefer the host's native structured question surface (Claude Code: AskUserQuestion; Codex: request_user_input; Hermes: clarify). If unavailable, present the same approval packet in plain chat; do not ask again for an exact route already approved by the parent.

Fresh identity and workspace

Local rebase must run in a newly established dedicated isolated workspace for the exact PR operation. "Newly established" is semantic: when the host has already placed this invocation in a fresh externally managed workspace dedicated to the exact PR/head, that boundary may be reused after provenance is proven; do not create a nested manual worktree merely to satisfy wording.

Before creating anything, inspect repository root, branch/HEAD, GIT_DIR, GIT_COMMON, and git rev-parse --show-superproject-working-tree or equivalent. GIT_DIR != GIT_COMMON is a linked-worktree signal only after excluding a submodule, and a linked worktree is not automatically owned by this PR.

When a new dedicated workspace is still required, inspect the current tool surface for concrete native entry points such as EnterWorktree, WorktreeCreate, /worktree, or --worktree; these are capability examples, not durable provider routing. Prefer an available agent-callable native worktree/workspace mechanism and fresh-read its path, branch or detached state, and HEAD. The explicit rebase request or an approved Sweep handoff already authorizes the exact isolation needed for that operation; do not ask another workspace-consent question. Use manual git worktree only when no safe native mechanism is available. The fallback must start from the exact old_head, avoid path/branch collisions and unrelated work, and be fresh-read after creation. Do not edit .gitignore or create a setup commit merely to enable the fallback. If the dedicated boundary cannot be created and proven fresh, return Blocked before mutation.

Host-managed workspaces keep their host-owned lifecycle. This skill does not remove, prune, relocate, or otherwise clean an externally managed workspace as part of rebase completion.

Fresh-read the following at the start.

• repository and authenticated identity
• open PR number
• head repository/ref/SHA
• base repository/ref/SHA
• local branch/HEAD/workspace provenance
• active Git operation
• review/thread/check state

If identity/ownership is ambiguous or the fork publication boundary cannot be proven safe, return Blocked before mutation.

Fetch the exact remote head and latest base, then freeze the following.

old_head
base_sha
full head ref
remote
expected force-with-lease

Require local HEAD == old_head, remote PR head == old_head, and a clean dedicated workspace.

Rebase and conflict

Rebase onto the exact base_sha. If a conflict occurs, apply the intent/index/marker/verification contract from tk-merge-conflict. Do not choose arbitrarily when semantic ambiguity exists.

After the rebase, verify the following.

• Git operation completed
• workspace/index clean
• base_sha is an ancestor of the new HEAD
• intended commit/diff preserved
• relevant tests/checks pass

Do not force-push if no rewrite is needed.

Standalone publication

An explicit standalone invocation automatically authorizes only the local rebase. Before remote publication, record the exact PR/base/head, old/new SHA, verification, exact lease/refspec, reply/thread action, and exclusions in an active approval packet. Keep a simple same-turn packet in the interaction when it can be faithfully retained and reread. Use the singleton .tigerkit/pr-rebase.md only for an explicit save, multi-turn handoff/recovery, complex conflict state, or when the host cannot retain the exact packet. Never create a per-run archive; when used, atomically replace stale completed content for this owner and reread it.

🔴 CHECKPOINT · 🛑 STOP · Standalone publication boundary

Do not tell the user merely to read an artifact. Naturally summarize what changed, what was verified, and which exact publication will be performed. Reuse an upfront request explicitly authorizing rebase and push to this target; ask once only if publication authority is absent. STOP immediately before the remote write if repository/identity/open state/base/head/refspec/lease cannot be rechecked or if any material drift invalidates the approval.

Only exact --force-with-lease=<full-head-ref>:<old_head> is allowed for publication. Plain --force is prohibited.

Execution under Sweep

If an active tk-pr-sweep has already approved the exact repository/PR/base/head and rebase route, do not repeat the publication question.

The Sweep handoff must include a newly established dedicated workspace path, exact approved head, and provenance sufficient to prove that workspace belongs to this PR row. The workspace may be host-native or a safe manual Git fallback; the child must not replace a proven host-owned workspace with a nested manual one. If path/HEAD/provenance is missing or not fresh, return Blocked before mutation. Run the child from that workspace; never switch the parent main or develop checkout to the PR branch.

A Sweep child must not create .tigerkit/pr-sweep.md or .tigerkit/pr-rebase.md. Return only the following compact evidence to the parent.

• repository/PR
• consumed base_sha / old_head
• verified new_head
• tests/checks
• exact lease/refspec
• remaining conflict/finding
• status

Recheck the exact PR/base/head immediately before child execution. If the head/base changed materially after parent approval, return only that PR to the parent as Blocked.

After publication

Verify that the remote PR head is new_head. Reply to or resolve only review threads actually satisfied by the rebase. Fresh-read every thread/review/check and do not hide unresolved findings as complete.

If needed, re-request review from an existing human reviewer, excluding the author, authenticated user, bots, and still-valid approvers. End generated GitHub comments with _🤖 본 코멘트는 AI가 작성했습니다._.

Status

Do not claim success for any reply/resolve/review/check state that was not observed.
