Superreview

Superreview

5-7 parallel perspective specialists with lane boundaries, shared concern tags, and a rigorous aggregation pipeline. Always runs cleanup pre-pass (reuse / quality / efficiency). Auto-detects spec/plan for coherence review.

NEVER review inline. Always dispatch subagents via the Agent tool.

Arguments

• [base..head | file-list | PR#] — diff source (default: branch diff vs parent)
• --auto critical|high|medium|all — auto-fix findings at or above the given severity. all = zero tolerance (every finding including nits gets fixed).
• --loop — enable fix + re-review loop. Without this, fixes are applied once with no re-review.

Step 1: Scope

Resolve BASE: gh stack view --json 2>/dev/null | jq -r '.trunk // empty' || gt parent 2>/dev/null || gt trunk 2>/dev/null || git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/||'. Args override.

Step 1.5: Cleanup Pre-pass

ALWAYS run unless #<PR> input. Spawn 3 agents in ONE message, each with the full diff. Wait for all three, aggregate findings, and apply each fix directly. Skip false positives without arguing, then proceed to Step 2.

Agent A — Code Reuse

You are reviewing a diff for missed opportunities to reuse existing code.

## Focus
1. **Existing utilities and helpers**: search utility directories, shared modules, and files adjacent to the changed ones. Flag any new function that duplicates existing functionality — name the existing function to use instead.
2. **Inline logic that could use an existing utility**: hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards.

Output: table with File:Line | Issue | Replacement. Brief summary.

Agent B — Code Quality

You are reviewing a diff for hacky patterns.

## Focus
1. **Redundant state**: duplicates existing state, cached values that could be derived, observers/effects that could be direct calls.
2. **Parameter sprawl**: new parameters added instead of generalizing or restructuring existing ones.
3. **Copy-paste with slight variation**: near-duplicate blocks that should unify behind a shared abstraction.
4. **Leaky abstractions**: internal details exposed, existing abstraction boundaries broken.
5. **Stringly-typed code**: raw strings where constants, enums (string unions), or branded types already exist.
6. **Unnecessary JSX nesting**: wrapper Boxes/elements that add no layout value — check if inner component props (flexShrink, alignItems, etc.) already provide the needed behavior.
7. **Unnecessary comments**: comments explaining WHAT, narrating the change, or referencing the task/caller — keep only non-obvious WHY.

Output: table with File:Line | Issue | Fix. Brief summary.

Agent C — Efficiency

You are reviewing a diff for efficiency problems.

## Focus
1. **Unnecessary work**: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns.
2. **Missed concurrency**: independent operations run sequentially when they could run in parallel.
3. **Hot-path bloat**: new blocking work added to startup or per-request/per-render hot paths.
4. **Recurring no-op updates**: state/store updates inside polling loops, intervals, or event handlers that fire unconditionally — add a change-detection guard. If a wrapper takes an updater/reducer callback, verify it honors same-reference returns so callers' early-return no-ops aren't silently defeated.
5. **Unnecessary existence checks**: pre-checking file/resource existence before operating (TOCTOU) — operate directly and handle the error.
6. **Memory**: unbounded data structures, missing cleanup, event listener leaks.
7. **Overly broad operations**: reading entire files when only a portion is needed, loading all items when filtering for one.

Output: table with File:Line | Issue | Fix. Brief summary.

Step 2: Setup + Context

ct tool gitcontext --base $BASE --stat --cochanges → diff-stat, changed-files, log, cochanges.

Auto-detect spec/plan for coherence review:

BRANCH_SLUG=$(git branch --show-current | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/-/g; s/-*$//')
PROJECT=$(git rev-parse --show-toplevel)
SPEC_FILE=$(ct vault search "$BRANCH_SLUG" --project "$PROJECT" --type spec 2>/dev/null | head -1)
PLAN_FILE=$(ct vault search "$BRANCH_SLUG" --project "$PROJECT" --type plan 2>/dev/null | head -1)

Set $HAS_SPEC = true if found. Read spec content for coherence reviewer. If spec found, run ct spec comments <file> — if non-empty, include as "Prior review annotations on the spec" in the coherence reviewer's prompt.

Detect primary language from changed file extensions. Set $LANG if one dominates.

Fetch PR context:

PR_CONTEXT=$(gh pr view --json title,body,labels -q '{title,body,labels}' 2>/dev/null || echo "")

Bugfix detection: If commit messages contain "fix"/"bugfix"/"hotfix", classify changed files as production vs test. ALL test-only → verdict FAIL with Critical: "Bugfix contains no production code changes."

Step 3: Dispatch Reviewers

All agents spawned in ONE message. Pass raw diffs — never summaries.

Large diffs (>3000 lines): Truncate files with >200 lines of diff to first 50 + last 50 lines. Note truncations.

Load perspective prompts from ${CLAUDE_SKILL_DIR}/perspectives/. Each file has a ## Prompt section.

Core (always): architect, code-quality, devils-advocate, operations, test-quality

Conditional (same message):

• perspectives/coherence.md — when $HAS_SPEC is true
• Language reviewer — when $LANG is set (template in ${CLAUDE_SKILL_DIR}/references/reviewer-prompts.md)

Additional (same message):

• Completeness — if cochanges non-empty
• Codex — if available AND (files≥5 or lines≥200), or if --auto all

Append protocol to every prompt:

## Protocol
Return COMPLETE findings as text. Do NOT write files.
Structure findings as phases:

**Phase 1: Critical Issues** — numbered list
**Phase 2: Design Improvements** — numbered list
**Phase 3: Testing Gaps** — numbered list

Only include phases that have findings. Skip empty phases.
For each finding: file, line(s), what's wrong, suggested fix.
Stay in your lane — only flag issues in your domain.
Exception: cross-cutting shared concerns tagged [shared:<category>].

Step 4: Aggregate

4a. Concatenate with source headers

4b. Group shared concerns

Collect [shared:<category>]-tagged findings. Group by category + file. Synthesize into multi-angle findings. Remove individuals from per-perspective sections.

4c. Consensus detection

Same file + same issue by 2+ perspectives = consensus. Critical from any reviewer survives. Non-critical needs 2+.

4d. Approach evaluation

1. Goal alignment: Does the diff achieve what the PR describes?
2. Premise check: Does the fix actually fix the stated problem?
3. Approach fitness: Right approach? Simpler alternatives?
4. Scope assessment: Appropriately scoped?

Rate: Sound | Minor Concerns | Significant Concerns | Alternative Recommended

4e. Correctness verification (MANDATORY)

Every finding verified against source. Read code at file:line ± 20 lines. Classify: Confirmed / False positive (REMOVE) / Pre-existing (downgrade) / Uncertain ([needs-review]).

Be aggressive about pruning. Log verification summary.

4f. Group by root cause

Multiple findings about same issue → ONE finding with multiple facets.

4g. Build unified output

Reviewer Summaries → Approach Assessment → Verification stats → Consensus findings → Perspective Disagreements → Design Coherence (if applicable) → Phase 1/2/3 non-consensus → Verdict (PASS / CHANGES_REQUESTED / FAIL)

Step 5: Store

Scaffold with blueprint_create { kind: "review", topic: "Review: <branch>" }, Edit the body with the review output, then blueprint_commit. Pass source: "<spec-stem>" if $HAS_SPEC.

Step 6: Fix

Determine fix scope from --auto:

• --auto critical → fix Critical only
• --auto high → fix Critical + High
• --auto medium → fix Critical + High + Medium
• --auto all → fix everything including nits
• No --auto → ask user what to fix

Spawn fix agent with FIX items → fix, verify, self-check, report.

--loop: Re-run Step 3 after fixes. Track fixed issues by (file, description). Max 4 iterations — unless --auto all which has no cap. Exit when zero findings remain, user stops, or cap hit.

Without --loop: single fix pass, no re-review.

Step 6b: Failure Learning

After fixes, check if Critical/High findings revealed a codebase-specific antipattern. If yes: create project rule in <project>/.claude/rules/<topic>.md.

Step 7: Summary + Next

Output: Fixes Applied, Ignored, Remaining. Suggest next steps.
