chorus-parallel-review

chorus-parallel-review is a skill for Claude Code, Codex from valpere/chorus. It costs 69 tokens per session (466 once invoked), scanned A, original, MIT.

A command that asks several coding agents to review the current Git changes, with each agent checking a different aspect of the work.

In plain words
What is it for?
Use it to review the current diff for correctness, security, robustness, codebase fit, maintainability, and unnecessary complexity.
Why use it?
A single review can miss security issues, edge cases, integration problems, or maintainability concerns.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chorus-parallel-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Chorus: Parallel Code Review

When to use

  • User wants code reviewed from multiple angles simultaneously
  • User says "parallel review", "all agents review", "chorus review"

Your role

You review for SCOPE AND SIMPLICITY: unnecessary complexity, changes exceeding the stated goal, simpler alternatives.

Invocation

git diff HEAD > /tmp/chorus_diff.txt

claude --print "Review for CORRECTNESS AND SECURITY. Numbered findings.\n\n$(cat /tmp/chorus_diff.txt)" --dangerously-skip-permissions &
CLAUDE_PID=$!

gemini --prompt "Review for EDGE CASES AND ROBUSTNESS. Numbered findings.\n\n$(cat /tmp/chorus_diff.txt)" --yolo --output-format text &
GEMINI_PID=$!

agent -p --force "Review for CODEBASE INTEGRATION. Numbered findings.\n\n$(cat /tmp/chorus_diff.txt)" &
CURSOR_PID=$!

kilo run --auto "Review for MAINTAINABILITY. Numbered findings.\n\n$(cat /tmp/chorus_diff.txt)" &
KILO_PID=$!

wait $CLAUDE_PID $GEMINI_PID $CURSOR_PID $KILO_PID

Graceful degradation: Check each agent with command -v <binary> before spawning. Skip missing agents and warn the user. Proceed as long as at least 2 agents (including yourself) are available.

Output handling

Synthesize all available reviews (up to four agents + your scope review):

## Parallel Review Summary
**Critical findings** (2+ agents): …
**Verdict**: <proceed / needs revision>

Review-only — do not apply patches.

Known limitation

Codex sandbox limits access to the current working directory. Reviews of files outside this scope will be incomplete.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
