+---
+
+# review-and-submit
+
+Lightweight autonomous pipeline: review code with a single agent, fix issues (up to 2 rounds), then create PR and merge. Designed for smaller PRs where full parallel review is overkill.
+
+**IMPORTANT**: Execute this entire process autonomously without asking the user for confirmation at any step.
+
+---
+
+## Process Overview
+
+```
+  REVIEW-FIX (max 2 rounds, 1 agent each)  →  CREATE PR  →  WAIT FOR CI  →  MERGE
+```
+
+---
+
+## Step 1: Review-Fix Loop (Max 2 Rounds)
+
+### Round Setup (first round only)
+
+Get the diff to understand what changed:
+
+```bash
+MERGE_BASE=$(git merge-base origin/main HEAD)
+git diff $MERGE_BASE --stat
+git diff $MERGE_BASE
+```
+
+### Each Round: Single-Agent Review
+
+Spawn **one** review agent that covers all review concerns:
+
+```
+Agent(
+  subagent_type: "general-purpose",
+  model: "opus",
+  description: "Review all changes on branch",
+  prompt: """
+    Review all code changes on this branch vs origin/main.
+
+    Run: git diff $(git merge-base origin/main HEAD)
+
+    Review for:
+    - Correctness and logical bugs
+    - Security issues
+    - Type safety issues
+    - Error handling gaps
+    - Performance problems
+    - Dead code or unused imports
+
+    **SCOPE**: Only report issues in changed code or directly caused by the changes.
+    Do NOT report pre-existing issues unrelated to this PR.
+
+    For each finding, output:
+    - File: path/to/file.ts
+    - Line: NN
+    - Severity: Critical|High|Medium|Low
+    - Issue: [description]
+    - Fix: [suggested fix]
+
+    If no issues found, say "No issues found."
+  """
+)
+```
+
+### Fix Phase
+
+If the review found issues:
+
+1. **Skip Low severity issues** — only fix Critical, High, and Medium
+2. Fix issues via a single fix agent:
+
+```
+Agent(
+  subagent_type: "general-purpose",
+  model: "opus",
+  description: "Fix review issues",
+  prompt: """
+    Fix the following review issues:
+
+    [LIST ALL CRITICAL/HIGH/MEDIUM ISSUES FROM REVIEW]
+
+    Instructions:
+    1. Read each file
+    2. Apply fixes using the Edit tool
+    3. Verify fixes don't break syntax
+    4. Report what was fixed
+  """
+)
+```
+
+3. After fixes, run typecheck:
+
+```bash
+pnpm typecheck 2>&1
+```
+
+If typecheck fails, fix type errors (up to 2 attempts).
+
+### Exit Conditions
+
+```
+IF (review found no Critical/High/Medium issues):
+    → EXIT loop — code is clean
+
+IF (fixes applied):
+    → Run another round to verify (unless already at round 2)
+
+IF (round 2 reached):
+    → EXIT loop
+```
+
+### Commit Changes
+
+After the review-fix loop completes, commit any changes:
+
+```bash
+if [ -n "$(git status --porcelain)" ]; then
+    git add -A && git commit -m "fix: address review findings"
+fi
+```
+
+**Continue to Step 2 — do not stop here.**
+
+---
+
+## Step 2: Create PR and Merge
+
+### 2a. Create PR
+
+```
+Use the Skill tool: skill: "create-pr"
+```
+
+After `/create-pr` completes, extract PR info:
+
+```bash
+gh pr view --json number,url --jq '.number, .url'
+```
+
+### 2b. Wait for CI Checks
+
+Wait **2.5 minutes** before the first poll:
+
+```bash
+echo "Waiting 2.5 minutes for CI checks..." && sleep 150
+```
+
+**CRITICAL**: Set `timeout: 210000` (3.5 minutes) on the Bash tool call for this sleep.
+
+### Poll for results (up to 5 polls, 90s apart)
+
+For each poll:
+
+```bash
+CHECKS=$(gh pr checks --json name,state,bucket 2>&1)
+echo "$CHECKS"
+
+if echo "$CHECKS" | jq -e 'length == 0' >/dev/null 2>&1; then
+    echo "RESULT:NO_CHECKS"
+elif echo "$CHECKS" | jq -e '[.[].bucket] | all(. == "pass" or . == "skipping")' >/dev/null 2>&1; then
+    echo "RESULT:PASSED"
+elif echo "$CHECKS" | jq -e '[.[].bucket] | any(. == "fail" or . == "cancel")' >/dev/null 2>&1; then
+    echo "RESULT:FAILED"
+else
+    echo "RESULT:PENDING"
+fi
+```
+
+- `PASSED` → Proceed to merge
+- `FAILED` → Attempt one quick fix iteration (diagnose from `gh run view --log-failed`, fix, push, re-poll)
+- `PENDING` → Wait 90s (`sleep 90`, `timeout: 150000`), then poll again
+- `NO_CHECKS` → Proceed to merge
+
+### 2c. Merge
+
+```bash
+IS_WORKTREE=false
+if [ "$(git rev-parse --git-dir)" != "$(git rev-parse --git-common-dir)" ]; then
+    IS_WORKTREE=true
+fi
+
+BRANCH=$(git branch --show-current)
+
+if [ "$IS_WORKTREE" = "true" ]; then
+    gh pr merge --admin --squash
+    git push origin --delete "$BRANCH" 2>/dev/null || true
+else
+    gh pr merge --admin --squash --delete-branch
+fi
+```
+
+---
+
+## CI Fix Loop (if checks fail)
+
+If CI fails after PR creation, run **one** fix iteration:
+
+1. Diagnose:
+
+```bash
+FAILED_RUN=$(gh run list --branch $(git branch --show-current) --limit 5 --json databaseId,conclusion,name --jq '[.[] | select(.conclusion == "failure")] | .[0].databaseId')
+if [ -n "$FAILED_RUN" ] && [ "$FAILED_RUN" != "null" ]; then
+    gh run view "$FAILED_RUN" --log-failed 2>&1 | tail -200
+fi
+```
+
+2. Fix the issues, run `pnpm typecheck`, commit and push:
+
+```bash
+if [ -n "$(git status --porcelain)" ]; then
+    git add -A && git commit -m "fix: address CI failures"
+    git push --force-with-lease
+fi
+```
+
+3. Wait 2.5 minutes and re-poll. If still failing after one fix attempt, merge with `--admin` anyway.

+
+## Critical Instructions
+
+1. **DO NOT ask for user confirmation** — Execute autonomously
+2. **Max 2 review rounds**, 1 agent per round — keep it lightweight
+3. **Only fix Critical/High/Medium** — skip Low severity
+4. **DO run typecheck** after fixes
+5. **DO use opus model** for review and fix agents
+6. **2.5 minute initial CI wait** (not 8 minutes) — this repo's CI is fast
+7. **DO use --admin --squash** for merge
+8. **DO set Bash timeouts** for sleep commands
+9. **Continue through all steps** — don't stop after review or PR creation
+10. **One CI fix iteration max** — don't loop forever on CI failures
