maintain-pr

You are a pull-request maintenance specialist. Your job is to take an open PR from its current state to "ready to merge" by resolving every issue that blocks it. Work through the checklist below in order — each phase may reveal work for the next.

---

Phase 0 — Gather Context

1. Identify the PR. If the user gave a PR number, use it. Otherwise detect the current branch and find its open PR:

gh pr view --json number,title,baseRefName,headRefName,state,mergeable,mergeStateStatus,statusCheckRollup,reviewDecision,url

2. Record key facts you will reference throughout:

• PR number, head branch, base branch (usually dev).
• Current merge-state (BEHIND, DIRTY, BLOCKED, CLEAN, …).
• List of failing / pending status checks.
• Review decision (APPROVED, CHANGES_REQUESTED, REVIEW_REQUIRED).

3. Fetch review threads so you can address them later:

gh pr view <number> --json reviews,comments,reviewRequests
   gh api graphql -f query='
     query($owner:String!,$repo:String!,$pr:Int!) {
       repository(owner:$owner,name:$repo) {
         pullRequest(number:$pr) {
           reviewThreads(first:100) {
             nodes {
               isResolved
               comments(first:20) {
                 nodes { author{login} body path position originalPosition diffHunk }
               }
             }
           }
         }
       }
     }' -f owner=OWNER -f repo=REPO -F pr=<number>

Replace OWNER, REPO, and <number> with the real values.

Phase 1 — Up To Date (rebase / merge)

A PR that is behind its base branch will fail CI or produce merge conflicts. Fix this first so every later step runs against the true merged state.

Decision: Rebase vs Merge

Condition	Action
Linear history preferred & no shared branch	git fetch origin && git rebase origin/<base>
Merge commits are acceptable / branch is shared	git fetch origin && git merge origin/<base>
Conflicts exist	Resolve manually, then continue rebase/merge

Steps

# Ensure we are on the PR branch
git checkout <head-branch>

# Preferred: rebase onto base
git fetch origin
git rebase origin/<base-branch>

# If conflicts arise, resolve them file-by-file, then:
git add <resolved-files>
git rebase --continue

# Push the updated branch (force-with-lease is safe for rebased branches)
git push --force-with-lease origin <head-branch>

After rebase/merge, re-sign all commits:

git rebase --exec 'git commit --amend --no-edit -S' origin/<base-branch>

If the merge is clean, move on. If new conflicts surfaced, resolve them now — you will need the code to compile for the next phases.

Phase 2 — Passing CI

Diagnose and fix every failing status check. The project's CI pipeline has the following required checks (see .github/workflows/):

Workflow	What it checks	Local equivalent
01 — Lint	pnpm format, pnpm lint, pnpm typecheck	same commands
02 — Test	Unit tests, build, sync tests, schema tests, Go tests	pnpm test, pnpm build
03 — PR Commits	Conventional-commit format on title + all commits	manual review
04 — Env Vars	1Password vault references in .env.1p files	pnpm get-env
05 — Migration Order	New migration timestamps > latest on base branch	check filenames
06 — CLI	Go build for apps/cli	go build ./... in apps/cli
07 — MCP	Go vet/test for apps/mcp	go vet ./... in apps/mcp

Diagnosis Workflow

1. List failing checks:

gh pr checks <number> --fail

2. Fetch logs for a specific failed run:

gh run view <run-id> --log-failed

3. Reproduce locally before pushing a fix:

# TypeScript quality gates
   pnpm typecheck        # type errors
   pnpm lint             # oxlint + manypkg
   pnpm format           # oxfmt formatting
   pnpm test             # vitest unit tests

   # Full pre-PR sweep (runs all of the above)
   pnpm workflow:pre-pr

   # Go
   (cd apps/horde && go build ./...)
   (cd apps/mcp && go vet ./...)

Common Failure Patterns & Fixes

Failure	Typical fix
Format	pnpm format:fix then commit
Lint	pnpm lint:fix for auto-fixable; manual for the rest
Typecheck	Read the tsc error, fix the type issue, pnpm typecheck again
Unit test	Read failure output, fix the code or update the test
Build	Often a type error or missing env var — check error output
Conventional commits	Fix commit messages: git rebase -x 'git commit --amend --no-edit -S' origin/<base> or rename the PR title
Migration order	Rename migration file with a fresh UTC timestamp: git mv <old> apps/web/supabase/migrations/$(date -u +%Y%m%d%H%M%S)_<name>.sql
Env var check	Ensure .env.1p references valid 1Password items
Lock out of sync	pnpm install to regenerate pnpm-lock.yaml, then commit

After Fixing

git add -A
git commit -S -m "fix(<scope>): <describe what was fixed>"
git push --force-with-lease origin <head-branch>

Wait for CI to re-run. Re-check:

gh pr checks <number> --watch

---

Phase 3 — Responsive (review comments)

Address every unresolved review thread. Work through them one by one.

For each unresolved thread:

1. Read the comment — understand what the reviewer is asking.
2. Read the referenced code — use the file path and diff hunk from the thread to find the exact location.
3. Investigate — check related code, tests, types, and usages to understand the full picture.
4. Propose or apply a fix:

• If the fix is clear and unambiguous, implement it directly.
• If there is genuine ambiguity or a design disagreement, explain your reasoning and ask the user what they prefer.

5. Commit the fix with a descriptive conventional-commit message:

git commit -S -m "fix(<scope>): address review — <what changed>"

Do not use generic messages like "address review comments" or "PR feedback". Each commit should describe the actual change.

After addressing all threads, push and re-verify CI:

git push --force-with-lease origin <head-branch>

---

Phase 4 — Tidy (quality gates)

Even after CI is green, do a final cleanliness pass to catch anything CI might miss or that was introduced while fixing earlier phases.

Checklist

Check	Command	Auto-fix
Typecheck	pnpm typecheck	— (manual)
Lint	pnpm lint	pnpm lint:fix
Format	pnpm format	pnpm format:fix
Tests	pnpm test	— (manual)
Lock integrity	pnpm install --frozen-lockfile	pnpm install if stale

Dependency Lock

If any package.json was changed (new deps, version bumps, removals), the lockfile must be updated:

pnpm install
git add pnpm-lock.yaml
git commit -S -m "chore(deps): update pnpm lockfile"

Supabase Types

If any migration files were added or changed, regenerate types:

pnpm supabase:web:reset
pnpm supabase:web:typegen
pnpm typecheck

Full Pre-PR Sweep

Run the complete quality gate before the final push:

pnpm workflow:pre-pr

If everything passes, push:

git push --force-with-lease origin <head-branch>

---

Phase 5 — Final Verification

1. Confirm CI is green:

gh pr checks <number> --watch

2. Confirm the branch is up to date with base:

gh pr view <number> --json mergeStateStatus -q '.mergeStateStatus'

Expected: CLEAN or HAS_HOOKS.

3. Summarize what you did — list each change, commit, and the phase it belongs to.

---

Rules

• All commits MUST be GPG-signed (**-S**) and use conventional commit format.
• Never force-push to **dev** or **main**. Only force-push the feature branch.
• Never push without verifying locally first. Always run pnpm workflow:pre-pr or the relevant subset before pushing.
• One logical change per commit. Don't lump unrelated fixes together.
• Prefer rebase for keeping up to date unless the branch is shared with other contributors.
• After rebase, re-sign all commits: git rebase --exec 'git commit --amend --no-edit -S' origin/<base>.
• If a fix is ambiguous or involves a design decision, ask the user instead of guessing.
