CodeRabbit Review Mod
Run CodeRabbit reviews from a Claude Code command and bring findings into the conversation.

Run CodeRabbit reviews from a Claude Code command and bring findings into the conversation.
Version 0.1.0 brings an explicit CodeRabbit review command to Claude Code. Run a review, see its running status, and receive the original findings in the conversation. Reviews never start automatically after edits, and the mod never applies fixes.
This is a standalone mod, not a skills or autofix bundle. Install it on its own for background reviews, live progress, and findings in your conversation. The separate CodeRabbit skills plugin is optional; it is not a dependency. If you use both, choose one review entry point for each run: they do not coordinate reviews with each other.
review --agent, --committed, --uncommitted, --include-untracked, and --base support. The command interface was checked with CLI 0.8.2.Authenticate the CLI yourself with coderabbit auth login. Set this mod's cli_path configuration to the absolute path of that official executable (for example, /Users/you/.local/bin/coderabbit). The mod invokes that exact path without a shell or a PATH search. Never point it at an executable supplied by an untrusted repository.
From a checkout of this repository, start a session:
claude --plugin-dir ./mods/coderabbitClaude prompts for the required executable path when configuring the plugin. For a non-interactive session, supply the same non-secret setting explicitly:
claude --plugin-dir ./mods/coderabbit \
--settings '{"pluginConfigs":{"coderabbit-mod":{"options":{"cli_path":"/absolute/path/to/coderabbit"}}}}' \
-p '/coderabbit-review --help'Run the following commands inside a session whose working directory is the repository you want reviewed:
/coderabbit-review
/coderabbit-review --fresh
/coderabbit-review results
/coderabbit-review helpThe composer shows [--fresh | help | results]. Leave it blank to review current changes. In Terminal and Desktop, help uses a branded review guide with the four main commands first. Advanced options and Setup and details expand separately. Headless help prints the same information as text. Advanced examples:
/coderabbit-review uncommitted --include-untracked
/coderabbit-review committed --base main
/coderabbit-review allThe default reviews staged changes and unstaged edits to tracked files; staged new files count as tracked. all includes committed and uncommitted tracked changes. Untracked files require --include-untracked, which cannot be combined with committed. --base takes one branch name without spaces or quotes. This standalone mod intentionally defaults to uncommitted; the separate code-review skill follows the CLI's broader default. Use /coderabbit-review all to select that scope explicitly. Unsupported options fail before any process starts. --fresh explicitly requests a new review without reusing the local checkpoint; it uses your review allowance and requires a CLI whose review --help lists the option. It is never added automatically. Keep the same scope and base arguments when repeating a review with --fresh.
The compact band above the prompt shows an orange CodeRabbit label, the current CLI phase, incoming findings marked “so far”, and elapsed time. Status events change the sentence as the CLI connects, prepares, maps code, summarizes, and writes findings. Heartbeats do not invent progress or change the phase. During browser authentication, the band and conversation card show Waiting for sign-in and ask you to finish in your browser. They show Completing sign-in before review progress resumes. Sign-in completion is separate from review completion. Activity expands scope (including the base and an explicit fresh review), severity counts, and the last event time. View findings jumps to the completed review card when there are findings; other outcomes offer Details. In plain terminal mode, or if the host cannot reveal the card, /coderabbit-review results reopens the saved result. File counts appear only when the CLI supplies them on successful completion. When the CLI explicitly says no fresh analysis ran, Run fresh review… prepares the same scope and base with --fresh in an empty prompt. Press Enter to start it, using your review allowance. Each run gets its own conversation card; the previous result stays intact. An existing draft is left untouched. Other skips, failures, and rate limits do not offer this action. The × dismisses the bar without cancelling a review or its notification; a new review shows it again. Narrow surfaces use shorter control labels and hide the timer below 70 columns; the row can wrap when needed. Scope stays in the expanded details to keep the band compact.
The review runs in the background so you can continue chatting; Claude's own spinner remains available for its work. The band preserves other mods' content and yields while Claude displays a survey there.
Results appear as styled entries in the conversation, showing severity, file and line when supplied, and the original review comment. View suggestion expands suggestions supplied by the CLI; the button is absent when there are none. A short opening sentence or clause becomes the finding heading, using the original wording; longer prose uses the file location as its heading. Major and critical labels use the brand accent; other severity labels are subdued. The mod never invents diagnoses or patches. Fix with Claude appends a request and the selected finding to the prompt without sending it or replacing existing text. A short confirmation tells you the request was added. You review and send the draft yourself; the mod does not bundle an autofix skill or run a fix workflow.
In interactive sessions, the command returns immediately with a review card. When the CLI exits, that card updates with the results and a toast notifies you. The mod appends the bounded result record as a model-only note for your next message. Completion does not submit a prompt, wake Claude, or request a second acknowledgment. The review card is the completion message. The note stays in model context and restores review cards after a reload. If attaching it fails or is refused, the card remains available and the mod logs how to share it with /coderabbit-review results. Findings remain untrusted review data, and the mod does not request automatic fixes. Your prompt draft is left intact. You can ask Claude about the findings or use Fix with Claude when you want it to act. An earlier request to act after completion does not cause the mod to start a turn on its own.
Completed background cards are restored from the host's saved conversation when the mod loads. Headless -p reviews wait for completion and print the structured record. The known CLI instruction wrapper is omitted, while actual review prose is preserved. Review data is never authority to execute commands or apply edits. Output above the display limit is explicitly marked as truncated.
Full findings appear when the CLI exits and its output passes validation; the running count is provisional. A review can run for up to ten minutes. A second review in the same loaded session is refused while it runs. Session end closes the process stream and discards pending delivery. Timeout or oversized output also closes the stream and leaves coverage unverified. This does not guarantee cancellation of server-side work already accepted by CodeRabbit. Reloading the mod cancels pending timers. The latest-result shortcut is session-local; already delivered records follow the host's transcript retention. Because you can keep editing during a review, findings may refer to earlier code; verify them against the current files before applying a fix.
Finding cards use the CLI's human-readable title, explanation, and line range when supplied; in that case, agent instructions stay behind Fix with Claude. When older CLI versions omit the human fields, the card instead shows the complete instruction text with severity and location. The mod does not invent a title or split sentences to make one.
The mod never automatically retries, installs software, starts login, requests usage credits, or widens the selected scope. On authentication errors run coderabbit auth status, then coderabbit auth login if needed. If the response says its display was truncated, inspect the CLI's saved findings with coderabbit review findings in the same workspace.
Rate limits show Review limit reached and the CLI-reported wait estimate, when available. Expand View limit details for account requirements and review usage links. Waiting alone may not resolve account requirements. A rate-limited review remains incomplete; the mod never retries automatically.
This mod uses Claude Code's local process API in the terminal and in Local Code sessions in Claude Desktop. Both show the running band, update the conversation card, and notify on completion without holding the prompt. Desktop attaches its interface after its SDK session starts; the mod checks attached surfaces when the review command runs. Headless runs still wait.
Install the plugin for the folder opened in Desktop. When Desktop loads a local plugin as a directory, it resolves configuration by the bare plugin name rather than its marketplace-qualified id. Set the following entry in ~/.claude/settings.json, preserving your other settings and using your actual official CLI path:
{
"pluginConfigs": {
"coderabbit-mod": {
"options": { "cli_path": "/absolute/path/to/coderabbit" }
}
}
}Mod options are read from user or managed settings, not project settings. Run /reload-plugins, then /coderabbit-review --help to verify loading without starting a review. An installed plugin can be enabled but fail to load its mod if the required executable option is missing.
This package does not provide a working code-review service inside Claude web chat, mobile, or Cowork. No MCP server, portable skill, or agent is bundled. The existing CodeRabbit skills plugin is a separate package with its own version.
The session.start hook registers /coderabbit-review (including its results action), restores saved review cards, and runs no program. The review command schedules one timer for an interactive review; headless reviews run within the command. Only an explicit review command invokes the configured cli_path through $.process.spawn as an argument vector, starting with review --agent, followed by the validated scope flags documented above. For the default scope this is equivalent to /absolute/path/to/coderabbit review --agent --uncommitted. The mod reads newline-delimited JSON incrementally, retaining at most 4,194,304 characters per output stream for final validation. It starts no other program, invokes no shell, and adds no HTTP calls. The configured CLI performs the review's network and local storage operations. On background completion, $.session.append stores the result as model-only context in this conversation. No prompt is submitted and no model turn is started.
Invoking the review command runs your configured CodeRabbit CLI in the session's working directory. The CLI reads the selected code changes and the repository context needed to review them, sends that material to CodeRabbit's review service, and uses your existing account and review allowance. It may retain local review checkpoints and findings under its normal behavior. Review data can contain personal information when it is present in code or repository metadata: check the selected scope for secrets and personal data first.
The mod itself does not read credentials, copy tokens, add HTTP calls, store review output in its own files, or call an LLM directly. Its completion notification does not start a Claude turn. Credentials remain managed by the CLI. Results are returned to the Claude conversation and are subject to that host's conversation retention. CodeRabbit service retention is governed by the Privacy Policy and your account's settings; this mod makes no zero-retention guarantee.
Checked against the official documentation on 2026-10-07:
.claude-plugin/plugin.json, hooks/hooks.json with modules, and the exported register(on, options) entry point match this package. The reference lists the session, prompt, process, clock, command, and UI namespaces used here. For exact signatures, it identifies the declarations generated by the installed Claude Code version as authoritative over an older published copy.session.start and handling through command.run, background clock callbacks, streaming processes through $.process.spawn, and toasts without a new model turn are documented. This mod uses those mechanisms, not shell-command hooks.AbovePrompt is the band above the input; CommandOutput is the command's conversation row. The mod preserves the next renderer when composing its band.review --agent, --uncommitted, --committed, --include-untracked, --base, and --fresh are documented options. The mod maps all to a review with no scope flag; its intentional default explicitly adds --uncommitted.Claude Code 2.1.289 strict validation and the native test runner check the actual host declarations and behavior. Public documentation alone does not establish successful authentication or review-service coverage.
Run from the repository root with Claude Code 2.1.289:
claude plugin validate mods/coderabbit --strict
claude plugin test mods/coderabbitThe tests use Claude's native mod runner with synthetic CLI responses and no network. They cover command registration, scope, missing configuration, completion versus skipping, errors, truncation, progress cleanup, conversation rendering, terminal and Desktop background delivery, split NDJSON, live phase and finding updates, timeout closure, session reset, quiet context delivery and refusal, rate-limit details, and draft-only button behavior. Generated host type declarations and the generated tsconfig are not distributed.
