coderabbit

coderabbit is a skill for Claude Code, Codex from dmythro/agent-skills. It costs 148 tokens per session (9,304 once invoked), scanned C, original, MIT.

A guide to the CodeRabbit command-line tool, which reviews code changes on your computer, and its repository configuration file.

In plain words
What is it for?
Use it to review uncommitted or committed changes, configure CodeRabbit with .coderabbit.yaml, check usage limits, and repeat a fix-and-review cycle. Reviews send the code diff and related context to CodeRabbit's service.
Why use it?
It helps find problems before changes are pushed or included in a pull request, reducing repeated review cycles. It also helps reduce noisy or duplicate findings.

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 C, and why

coderabbit scanned grade C with 2 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 9d 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.

CodeRabbit CLI and Configuration

Local-first AI code review: catch issues before they reach the PR. The CodeRabbit CLI (coderabbit, alias cr) reviews working-tree or branch changes locally, so the PR-side review becomes confirmation instead of iteration -- this saves billable PR review rounds (both CodeRabbit's own quota and any Copilot credits). Covers the CLI surface -- local reviews, plus the beta cloud Coding Agent commands -- and .coderabbit.yaml tuning. PR-side mechanics (threads, re-requests, the bot loop) live in the git-pr skill.

Verified against CodeRabbit CLI v0.9.0 (2026-10-10): every subcommand's --help on the official build, diffed against v0.8.2, plus the CLI changelog and the agent-mode and cloud-task pages it links. Flags are tagged with the version that introduced them. The billed and pushing coderabbit code commands were not exercised; their handling comes from those docs. If coderabbit --version reports something newer, diff --help of each subcommand against this list and read the changelog entries since v0.9.0 before relying on flag details here.

When to Use

  • Reviewing local changes -- "review my changes", "run coderabbit", pre-commit/pre-push/pre-PR checks
  • Driving a review-fix loop -- run review, fix valid findings, re-run to verify
  • Configuring CodeRabbit -- create or tune .coderabbit.yaml, reduce review noise, disable redundant linters
  • Checking limits -- rate limits per plan, review budgeting
  • Setting up the CLI -- install, auth, updates, headless/CI usage
  • Running cloud Coding Agent tasks -- coderabbit code new/resume/push, handing a local session off to the cloud (beta, v0.9.0)

Critical Rules

  1. Reviews upload code to CodeRabbit's service. A review sends the diff (and context) to CodeRabbit. On a repo with sensitive/unpublished code, confirm the user is OK with that before the first run.
  2. Reviews consume a per-hour quota (Free: 3/hour CLI reviews). Scope deliberately (--committed/--uncommitted, --base) and use coderabbit review findings to replay the last result without spending a review.
  3. Use --agent output when driving fixes programmatically; the default plain-text mode is for humans. There is no --plain flag: v0.7 removed it, and it fails with error: unknown option plus the usage text (v0.9 adds a Remove --plain hint). v0.8+ exits 1 on it; v0.7 exited 0, so on an older binary a piped or tailed run looks clean while nothing was reviewed. Do not guess flags: coderabbit review --help on the installed binary is the supported surface, and the hidden legacy aliases it omits still parse -- --type <all|committed|uncommitted> and --light both start a real review.
  4. Validate findings before fixing -- same rule as PR reviews: judge each finding on its merits; never blind-fix to silence the tool.
  5. CodeRabbit is optional -- check the Code Review Policy first (repo AGENTS.md/CLAUDE.md, falling back to the user's global agent instructions; see git-pr skill) for the preferred reviewer and checkpoints. Never install, authenticate, or run it on a project whose policy or user hasn't opted in.
  6. coderabbit code spends money and pushes code. new, ask, and messages sent through resume start billed agent work; push and Autopilot write to the repository. Run them only on the user's explicit request, and never rerun one that already reported its commit point -- the rerun duplicates the billed work (references/cloud-tasks.md).

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.

coderabbit is a skill published in the GitHub repository dmythro/agent-skills (7 stars, last pushed 10d ago), licensed MIT. It adds 148 tokens to every session and 9,304 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
