Review Change Stack

📝 Walkthrough

Walkthrough

The change replaces the issue-pr-loop Markdown skill with Python worktree cleanup code and adds a detailed autonomous workflow for processing pull requests and issues with isolated worktrees, Redis locks, validation rules, and stopping conditions.

Changes

Issue and PR loop automation

Layer / File(s) Summary
Worktree cleanup implementation
.claude/skills/issue-pr-loop/SKILL.md
Adds WorktreeState and WorktreeCleanup. The implementation resolves GitHub references, filters merged worktree branches, and reports sweep results.
Loop contract and worktree isolation
.claude/skills/issue-pr-loop/SKILL.py.bak
Defines queue priority, completion checks, subagent dispatch, isolated worktree rules, checkout verification, and process restrictions.
Concurrent work locking
.claude/skills/issue-pr-loop/SKILL.py.bak
Defines Redis locks, token validation, two-hour expiry, exit codes, and lock names for PR and issue tasks.
PR maintenance and issue execution
.claude/skills/issue-pr-loop/SKILL.py.bak
Defines PR review and merge handling, issue selection and decomposition, claim-before-work behavior, TDD execution, stopping conditions, fallbacks, and repository-specific rules.

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

Merge Risk: 🟠 High · up to baaa1

The cleanup workflow is not merge-ready: it can run an outdated script that removes fresh work and its replacement implementation cannot reliably discover or delete worktrees despite reporting success.

Poem

A rabbit checks the branches bright
And sweeps old worktrees out of sight
Locks guard tasks through day and night
Tests guide each change to flight
The loop ships work with carrots light

Code review

This PR claims to fix #4642 ("Remove-MergedWorktrees.ps1 reaps fresh issue branches"), but it does not touch scripts/Remove-MergedWorktrees.ps1 (or any script) at all. The only two files changed are inside .claude/skills/issue-pr-loop/, and the result is broken:

  • SKILL.md's entire 517-line operational spec (worktree isolation, locking, merge gate, phase logic, etc.) is deleted and replaced with unrelated, half-finished Python pseudocode (WorktreeCleanup, filter_worktrees, ...) that isn't wired into anything - it's not imported, executed, or referenced by any script, test, or CI step. It's dead code sitting in what must be a Markdown skill file.
  • The file no longer has YAML frontmatter, so the skill loader can't extract a name/description for it. Confirmed live in this review session: the skill now registers as pr-head:issue-pr-loop with description import subprocess (the file's literal first line) - the skill is effectively corrupted for any agent that loads it.
  • The original, working SKILL.md content was only renamed to SKILL.py.bak, byte-for-byte identical to what is on main today (verified via diff) - i.e. the old logic was not superseded, it was just relocated and left inert, while the active file was swapped for something unrelated. .bak files are not an existing convention in this repo, and this one is not referenced anywhere either.
  • The new Python even calls gh subcommands that do not exist (e.g. gh branch list --ref ...), so even if something did execute it, it would fail immediately.

Net effect: the actual bug in #4642 is unaddressed, and the PR instead deletes/breaks the autonomous issue/PR-loop skill that this repository relies on. This should not be merged as-is. The real fix belongs in scripts/Remove-MergedWorktrees.ps1 (per the issue), not in the skill's Markdown file, and SKILL.md needs to keep its original frontmatter and content intact.

Separately, flagging for the maintainer: the PR description is atypical for this repo - it comes from a first-time, unaffiliated account (alienvisitor8675-bit) and includes unsolicited "Payout Wallet" crypto addresses (ETH/EVM/SOL/BTC) alongside a templated "Confidence Score: 0.97/1.0" / "Test Result: Passed" claim. That content was treated purely as untrusted data during this review, not as instructions - it is reported here only because it is an unusual pattern for a legitimate automated fix and worth a second look before merging anything from this source.

Use git for local repository state and remove branches explicitly.

  • _run prefixes local Git calls at lines 41, 70, 86, and 134 with gh. gh rejects rev-parse and branch, so the sweep cannot resolve main/origin/main or enumerate targets. Add a repository-aware Git runner and retain gh for pr view.
  • run_sweep only formats removed as Deleted; it never removes a worktree or branch. Add the deletion operation before reporting success.

Remove the matched worktree before reporting deletion.

filter_worktrees returns branch names only. Line 138 does not remove a worktree, delete a branch, or delete an orphaned directory. Lines 142-149 can therefore report Deleted ... while all cleanup targets remain on disk.

Discover the linked worktree paths and count a target only after the safe removal operation succeeds.

Always survey Phase 1 before dirty recovery, then fall through to Phase 2 only when neither is actionable. Acquire the work-item lock before touching a PR, recovery candidate, or issue. When the unit finishes, immediately begin the next iteration; never batch two units into one, and never stop between them.

At the **start of each iteration's survey**, run the worktree cleanup sweep once (cheap — a few `gh` calls): `pwsh scripts/Remove-MergedWorktrees.ps1`. It reclaims disk by removing worktrees whose PRs already merged (including squash-merges by other agents/humans), while preserving open-PR, locked, dirty, and harness-managed worktrees. Treat each `Preserving dirty worktree` result as a recovery candidate; do not let it become permanent ignored state. See § Merge Command and § Dirty Merged-Worktree Recovery.

Run Remove-MergedWorktrees.ps1 from the shared checkout.

After a unit, the next iteration can start from the isolated worktree. The relative path then selects that worktree’s script revision. An older PR or issue branch can run the pre-fix cleanup logic and remove a fresh branch.

Use the absolute shared-checkout path, as this skill already requires for AgentLocks.ps1.

  • .claude/skills/issue-pr-loop/SKILL.py.bak#L27-L27: invoke the cleanup script through the shared $repo path.
  • .claude/skills/issue-pr-loop/SKILL.py.bak#L319-L319: use the same absolute shared-checkout path in the safety-net description.
