| ## How to Review | ||
|
|
||
| ### 1. Check CLI and Authentication | ||
|
|
||
| Resolve the host-installed `coderabbit` to its canonical absolute path. Trust | ||
| and execute only that path when it is an expected user or system binary; reject | ||
| repository, workspace, and temporary paths. Keep discovery sandboxed. If it | ||
| fails or the path is untrusted, report CLI availability as unknown and stop; do | ||
| not claim it is uninstalled. Point the user to <https://www.coderabbit.ai/cli>. | ||
|
|
||
| Run `"/absolute/path/to/coderabbit" auth status --agent` in the same context | ||
| that will run the review. For a local sandboxed agent, use command-scoped host | ||
| execution; in Codex, set `sandbox_permissions: require_escalated` on that exact | ||
| tool call. A sandbox-only result is not authoritative. Host-native agents use | ||
| their normal shell; remote and cloud agents use only their environment's auth. | ||

💡 Result: In the OpenAI Codex CLI, sandbox permissions and escalation requests are governed by the tool's execution policy, which defaults to the on-request approval model [1][2]. Under this policy, commands are executed within a sandbox by default unless a specific override is requested [1]. When a task requires escalated privileges that the default sandbox environment does not permit, the agent is instructed to use the sandbox_permissions and justification parameters within the tool call [1]. The specific request path and parameters are as follows: 1. Sandbox Permissions: To request execution outside the sandbox, the agent sets the sandbox_permissions parameter to "require_escalated" [3][1]. An alternative, "with_additional_permissions," may be used if the agent needs to stay sandboxed but requires widened permissions for that specific command only [3][4]. 2. Justification: Every request for escalated permissions must be accompanied by a justification parameter [3][1]. This should contain a concise, single-sentence explanation detailing why the escalated permissions are necessary to complete the user's task [1]. 3. Approval Policy: The CLI evaluates these requests based on the configured approval policy (e.g., on-request or granular) [2]. If the approval policy is set to on-request, the system prompts the user for consent when a command requests an explicit sandbox override [1][4][2]. The agent is explicitly instructed not to message the user before requesting approval, but rather to include these parameters directly in the tool call if a command fails due to sandboxing [1]. These protocols are managed internally by the Codex protocol, which maps the requested sandbox permissions to the appropriate execution environment [3][5][6]. If the environment is already unrestricted (e.g., under a full-access profile), explicit escalation requests may be omitted or treated as no-ops depending on the specific configuration [7].

| For a local sandboxed agent, use command-scoped host execution; in Codex, set | ||

| check and review invocations authorized by the current task are eligible. Each | ||
| must directly invoke the absolute path with literal, validated arguments—no | ||
| wrappers, pipes, expansions, or session-wide sandbox changes. All other | ||
| CodeRabbit operations are out of scope; only `--version` or `--help` diagnostics | ||
| may run sandboxed. | ||

💡 Result: In the CodeRabbit CLI, these terms refer to specific event types emitted during the review process. When the CLI is executed, it streams various events that provide updates on the review's progress [1]. The specific events you mentioned function as follows: review_context: This event provides the initial context for the review [1]. status: This event reports the current state of the review process [1]. heartbeat: These are periodic keep-alive signals sent to ensure the connection remains active; they should be ignored by your implementation and used only to reset timeout timers [1]. finding: This event represents an issue or suggestion identified by the agent. When handling findings, the CLI suggests using codegenInstructions for automated fixes, falling back to a standard comment if instructions are unavailable [1]. error: This event is emitted if a failure occurs during the process [1]. complete: This event indicates that the review process has finished [1]. Regarding the review_skipped status, if the CLI is run on a scope with no detected file changes, it will emit a review_context event followed by a status event with status: "review_skipped" and a complete event indicating the same, along with a message stating "No changes detected" and a findings count of 0 [1].

💡 Result: The CodeRabbit CLI (cr) provides a comprehensive set of options for configuring local code reviews. Based on the official documentation, the flags you mentioned function as follows: --agent: Configures the CLI to output structured JSON instead of plain text, which is designed for integration with coding agents and automation workflows [1]. --base : Specifies the base branch to be used for the comparison, allowing you to define the target against which your current changes are reviewed [1]. --base-commit : Specifies a particular commit on the current branch to be used as the base for the comparison [1]. --include-untracked: Instructs the CLI to include non-ignored files that have not yet been added to the Git index (tracked) in the review process [1]. In addition to these, the CLI supports other related options such as --committed (review only committed changes), --uncommitted (review staged and unstaged edits to tracked files), and various authentication and configuration validation commands [1]. You can use the cr doctor command to verify your CLI installation and configuration if you encounter issues [1]. Citations: 🏁 Script executed: #!/bin/bash

🌐 Web query:
💡 Result: The SKILL.md specification is a standard format used to define reusable capabilities for AI agents [1][2][3]. The canonical specification is maintained at agentskills.io [1][4]. A skill is defined as a directory containing at least one SKILL.md file [1][5]. This file utilizes YAML frontmatter for structured metadata, followed by Markdown content that provides the instructions, workflows, and guidance an agent uses to perform tasks [1][6][7]. Required Metadata Fields The following fields are required in the YAML frontmatter [1][6][7]: - name: A unique identifier (max 64 characters; lowercase letters, numbers, and hyphens only). - description: A summary (max 1024 characters) that explicitly details what the skill does and when an agent should use it. Optional Metadata Fields Common optional fields include [1][6]: - license: License information or a reference to a bundled license file. - compatibility: Environment or system requirements (max 500 characters). - metadata: An arbitrary key-value mapping for additional data. - allowed-tools: A space-separated list of pre-approved tools (experimental). Operational Architecture When an agent is triggered, it reads the SKILL.md file from the filesystem to pull instructions into its context window [7]. The body of the file is not strictly formatted, allowing authors to include prose, code blocks, or references to other files (such as scripts or supporting documentation) within the same directory [1][7]. Ecosystem Variations While the agentskills.io specification serves as the baseline, various projects implement extensions [2][3][8][5]. For example, some specifications (like AIP-3 or proprietary extensions) may add fields such as versioning, input/output schemas, dependency management (e.g., for MCP servers), and security/permission models [3][8][5]. Despite these variations, most implementations remain backward compatible with the core agentskills.io format [2][5]. Citations:

💡 Result: The AGENTS.md format is an open, community-driven standard designed to serve as a README specifically for AI coding agents [1][2][3]. It provides a predictable location for developers to store instructions, context, and conventions that help agents work more effectively with a codebase [1][4]. Key specifications of the AGENTS.md format include: Standard Format: It uses standard Markdown (CommonMark compatible) with no rigid schema or required fields [1][5][4]. The agent parses the text and headings provided, allowing for flexible organization such as project overviews, build/test commands, and code style guidelines [1][3][5]. File Naming and Location: The canonical filename is exactly AGENTS.md (case-sensitive) [6][5][4]. It is typically placed at the repository root, though it can be placed in subdirectories or packages to provide tailored instructions for specific project segments [1][7][5]. Precedence and Resolution: When multiple AGENTS.md files exist, the file closest to the directory of the file being edited takes precedence [1][7][4]. Explicit user chat prompts always override instructions found in AGENTS.md files [1][7][4]. Optional Extensions: While the core format is simple Markdown, specifications exist for optional YAML frontmatter (using --- delimiters) to support features like progressive disclosure, allowing agents to identify file relevance via metadata such as description or tags [6]. Adoption: The format is intended to be tool-agnostic and is supported by various AI development tools and environments [1][3][7]. Official documentation and community discussions are maintained at agents.md and the associated GitHub repository [3]. Citations:

💡 Result: CodeRabbit does not have a public, standalone documentation file named code-reviewer.md specifically designated as the host agent configuration for general public users. However, in the context of the CodeRabbit Cursor plugin, there is an agents/code-reviewer.md file located within the repository structure [1]. In the broader CodeRabbit ecosystem, instructions for AI agents are typically handled via standardized configuration files that CodeRabbit automatically detects and uses as review criteria [2]. These files include: * AGENT.md and AGENTS.md: Used for general AI agent instructions [2]. * Other standard files: CodeRabbit automatically scans for and applies configurations from files such as.cursorrules, CLAUDE.md,.github/copilot-instructions.md, and.windsurfrules to enforce coding standards during reviews [3][2]. For users looking to configure CodeRabbit behavior, the official documentation specifies that configuration should be managed via a.coderabbit.yaml file in the repository root [3]. Self-hosted deployments, which involve running the CodeRabbit review agent within private infrastructure, are configured through specialized setup processes coordinated with the CodeRabbit team rather than through a public code-reviewer.md document [4].

💡 Result: Git does not have a native flag or option to include untracked files directly in a commit. To include untracked files in a commit, you must first stage them using the git add command. Standard Git workflow requires files to be tracked and staged before they can be committed. While some third-party CLI tools, such as CodeRabbit, provide an --include-untracked flag for their own operations like code reviews, this functionality does not exist within the core git commit command [1]. To include untracked files in your next commit, you must manually add them: git add git commit -m "Your commit message" Citations: 🌐 Web query:
