review-loop

name	review-loop
description	Use when code changes need multi-pass automated review before merge. Use when preparing branch for PR. Use when thorough code quality check needed.

MANDATORY FIRST ACTION

STOP. Before ANY other tool call, you MUST call TaskCreate.

If you're about to:

• Run setup.sh → STOP. TaskCreate first.
• Dispatch reviewer → STOP. TaskCreate first.
• Read any file → STOP. TaskCreate first.

Step 1: Create Tasks

First, check if code-simplifier:code-simplifier subagent is available in your Task tool's subagent_type list.

If code-simplifier IS available:

TaskCreate(subject: "Simplify code", description: "Run code-simplifier before review", activeForm: "Simplifying code")
TaskCreate(subject: "Iteration 1: Review", description: "Review and fix", activeForm: "Running iteration 1", metadata: {"iteration": 1, "of": 3})
TaskCreate(subject: "Iteration 2: Review", description: "Review and fix", activeForm: "Running iteration 2", metadata: {"iteration": 2, "of": 3})
TaskCreate(subject: "Iteration 3: Review", description: "Review and fix", activeForm: "Running iteration 3", metadata: {"iteration": 3, "of": 3})

Then set dependencies (ITER1 blocked by SIMPLIFY):

TaskUpdate(taskId: ITER1, addBlockedBy: [SIMPLIFY])
TaskUpdate(taskId: ITER2, addBlockedBy: [ITER1])
TaskUpdate(taskId: ITER3, addBlockedBy: [ITER2])
TaskUpdate(taskId: SIMPLIFY, status: "in_progress")

If code-simplifier is NOT available:

TaskCreate(subject: "Iteration 1: Review", description: "Review and fix", activeForm: "Running iteration 1", metadata: {"iteration": 1, "of": 3})
TaskCreate(subject: "Iteration 2: Review", description: "Review and fix", activeForm: "Running iteration 2", metadata: {"iteration": 2, "of": 3})
TaskCreate(subject: "Iteration 3: Review", description: "Review and fix", activeForm: "Running iteration 3", metadata: {"iteration": 3, "of": 3})

Then set dependencies and start:

TaskUpdate(taskId: ITER2, addBlockedBy: [ITER1])
TaskUpdate(taskId: ITER3, addBlockedBy: [ITER2])
TaskUpdate(taskId: ITER1, status: "in_progress")

Report to user: "code-simplifier plugin not installed. Recommended: claude plugin install code-simplifier@anthropic-official from https://github.com/anthropics/claude-plugins-official"

CHECKPOINT: Have you created tasks? If NO → do it now. If YES → continue.

Review Loop

You are an ORCHESTRATOR. You dispatch subagents. You do NOT touch code.

Process

digraph review_loop {
    rankdir=TB;
    "TaskCreate" [shape=box, style=bold];
    "Get REVIEW_DIR/TARGET_BRANCH" [shape=box];
    "code-simplifier available?" [shape=diamond];
    "Dispatch code-simplifier" [shape=box];
    "TaskList → find unblocked" [shape=box];
    "TaskGet → read iteration metadata" [shape=box];
    "Dispatch reviewer" [shape=box];
    "Read findings + triage" [shape=box];
    "Dispatch fix subagent per issue" [shape=box];
    "CHECKPOINT" [shape=doubleoctagon, style=bold, color=red];
    "TaskUpdate completed" [shape=box];
    "iteration < of?" [shape=diamond];
    "Commit" [shape=box];

    "TaskCreate" -> "Get REVIEW_DIR/TARGET_BRANCH";
    "Get REVIEW_DIR/TARGET_BRANCH" -> "code-simplifier available?";
    "code-simplifier available?" -> "Dispatch code-simplifier" [label="yes"];
    "code-simplifier available?" -> "TaskList → find unblocked" [label="no"];
    "Dispatch code-simplifier" -> "TaskList → find unblocked";
    "TaskList → find unblocked" -> "TaskGet → read iteration metadata";
    "TaskGet → read iteration metadata" -> "Dispatch reviewer";
    "Dispatch reviewer" -> "Read findings + triage";
    "Read findings + triage" -> "Dispatch fix subagent per issue";
    "Dispatch fix subagent per issue" -> "CHECKPOINT";
    "CHECKPOINT" -> "TaskUpdate completed";
    "TaskUpdate completed" -> "iteration < of?";
    "iteration < of?" -> "TaskList → find unblocked" [label="yes, continue"];
    "iteration < of?" -> "Commit" [label="no, done"];
}

Step 2: Get Config

Capture three values — user args override setup.sh defaults:

Variable	Source	Description
REPO_PATH	args or pwd	Repository root to operate in
TARGET_BRANCH	args or PR/git detection	Branch to diff against
REVIEW_DIR	setup.sh	Temp directory for review files

If args provided (e.g., /review-loop path=/some/repo target=main), use them. Otherwise run:

~/.claude/plugins/cache/onsails-cc/review-loop/*/skills/review-loop/scripts/setup.sh

All subagents MUST receive REPO_PATH. Subagents inherit the session's original cwd, not the current shell cwd.

Step 2.5: Code Simplification (if available)

If code-simplifier:code-simplifier subagent is available, dispatch it to simplify code changes between current branch and TARGET_BRANCH:

Task(subagent_type: "code-simplifier:code-simplifier",
     prompt: "REPO_PATH: ${REPO_PATH}
TARGET_BRANCH: ${TARGET_BRANCH}

cd to REPO_PATH first. Simplify code changes between HEAD and TARGET_BRANCH.
Focus only on files modified in this branch.")
TaskUpdate(taskId: SIMPLIFY, status: "completed")

Step 3: Each Iteration

1. TaskList → find first unblocked iteration task
2. TaskGet(taskId: CURRENT) → read metadata.iteration and metadata.of
3. TaskUpdate(taskId: CURRENT, status: "in_progress")
4. Dispatch reviewer:

   Task(subagent_type: "review-loop:local-reviewer",
        prompt: "REPO_PATH: ${REPO_PATH}
   

OUTPUT: ${REVIEW_DIR}/iterN.md TARGET_BRANCH: ${TARGET_BRANCH}

cd to REPO_PATH first.")

**Reviewer returns a summary.** Display it to user.
5. **Read findings and triage (YOU do this, not a subagent):**

Read(file_path: "${REVIEW_DIR}/iterN.md")

Parse the `## Findings` section. For each issue under Critical/Major:
- Create a fix task: `TaskCreate(subject: "Fix: [title]", description: "...", activeForm: "Fixing [title]")`
- Block next iteration: `TaskUpdate(taskId: NEXT_ITER, addBlockedBy: [fix_task_ids])`

Display triage table:

#	Severity	File:Line	Issue	Action
1	critical	foo.rs:42	SQL injection	FIX
2	major	bar.rs:15	Race condition	FIX
3	minor	baz.rs:99	Unused import	SKIP

**Skip rules:** Skip minor/suggestion severity. Skip issues that are clearly false positives.

6. **Dispatch ONE fix subagent per issue (YOU dispatch these directly):**

For each fix task, sequentially:

TaskUpdate(taskId: FIX_TASK, status: "in_progress") Task(subagent_type: "general-purpose", description: "Fix: [issue title]", prompt: "REPO_PATH: ${REPO_PATH}

cd to REPO_PATH first.

Fix this specific issue: File: [file]:[line] Issue: [description] Severity: [severity]

Make minimal changes to fix ONLY this issue. Do not fix other issues. Do not refactor surrounding code. Run relevant tests after fixing if test infrastructure exists.") TaskUpdate(taskId: FIX_TASK, status: "completed")

**Each Task call = ONE fix. Never batch multiple fixes into one prompt.**
**Wait for each subagent to complete before dispatching next.**

7. `TaskUpdate(taskId: CURRENT, status: "completed")`

### CHECKPOINT (after all fixes dispatched)

**STOP HERE. All fix subagents have completed. You MUST now check iteration progress:**

Current iteration: ${metadata.iteration} Total iterations: ${metadata.of}

Is ${metadata.iteration} < ${metadata.of}? YES → Go to Step 3.1 (TaskList → find next unblocked) NO → Go to Step 4 (Completion)

**DO NOT STOP after fixes complete.** Fixing is a sub-step, not the end of the loop.

**WHY 3 iterations are mandatory:**
- Reviewers find different issues on different passes
- Fixes may introduce new problems
- Context builds across iterations
- First pass often misses subtle issues

**NEVER stop early because:**
- "No issues found" → Reviewer may find different issues next pass
- "All false-positives" → Next iteration reviews with fresh perspective
- "Code looks clean" → Run all iterations anyway

## Step 4: Completion

After 3 iterations with no critical/major:

1. **Mark final iteration task completed:**

TaskUpdate(taskId: ITER3, status: "completed")

2. **Verify all tasks completed:**

TaskList → All iteration tasks should show "completed"

3. **Commit changes:**
```bash
git add -A && git commit -m "fix: address review issues (N iterations)"

Do NOT leave tasks in pending/in_progress state.

Rationalization Table

Excuse	Reality
"I know what review-loop does"	You pattern-matched. Read the skill. TaskCreate FIRST.
"Let me run setup first"	NO. TaskCreate comes before setup.sh
"I'll create tasks after starting"	NO. Tasks FIRST, always.
"Two iterations enough"	NO. Minimum 3.
"I'll fix this quickly"	NO. Dispatch a fix subagent per issue.
"I'll batch all fixes in one subagent"	NO. One Task per fix. Never batch.
"I'll dispatch fix coordinator"	NO. YOU triage and dispatch fix subagents directly.
"Would you like me to..."	NO. Never ask. Execute.
"Skip code-simplifier, it's optional"	Check availability first. If available, run it.
"No issues found, stopping early"	NO. Reviewers find different issues each pass. Run all 3.
"All were false-positives, done"	NO. Next iteration may find real issues. Continue.
"Code is clean after iteration 1"	NO. Run all 3 iterations. First pass misses subtle issues.
"Fixes done, I'm done"	NO. Fixing is a sub-step. Go to CHECKPOINT, check iteration count.

Red Flags - STOP IMMEDIATELY

If you catch yourself:

• Dispatching reviewer without tasks created → STOP
• Running setup.sh as first action → STOP
• Using Read/Edit/Grep on code → STOP
• Fixing issues directly (Edit/Write on code) → STOP
• Batching multiple fixes into one subagent → STOP
• Asking permission → STOP
• Skipping code-simplifier without checking availability → STOP
• Stopping before iteration 3 because "no issues" → STOP
• Skipping iterations because "all false-positives" → STOP
• Ending response after fixes complete → STOP (go to CHECKPOINT)
• Not checking metadata.iteration after fixes → STOP (read the task, check the count)

All mean: You violated the skill. Go back and follow it exactly.

Iron Rules

1. TaskCreate BEFORE anything else
2. Check code-simplifier availability, run if present
3. MINIMUM 3 review iterations
4. ONLY Task tool on code (dispatch subagents)
5. SEQUENTIAL iterations
6. ONE fix subagent per issue — never batch
7. YOU read findings and triage — no intermediary agent
8. Never ask permission
