OpenAI Codex CLI current documentation for sandbox_permissions require_escalated justification approval policy on-request permission request path
💡 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].

🌐 Web query:
site:github.com/openai/codex "Granular approval" "sandbox_permissions" "justification"
💡 Result:
The sandbox_permissions and justification parameters are technical fields used in tool calls—specifically for executing shell commands—to manage security, sandbox overrides, and user authorization [1][2]. Their core function and usage depend on the configured approval_policy [3][4]: 1. Sandbox Permissions (sandbox_permissions): This parameter defines how a specific command interacts with the execution environment's sandbox [5]. Common values include: - UseDefault: Executes the command with the standard, unchanged turn sandbox [5]. - RequireEscalated: Requests that the command be executed outside the sandbox [5]. This is typically used when a task necessitates higher privileges than the default environment provides [6]. - WithAdditionalPermissions: Executes the command within the sandbox but with broadened permissions for that specific operation [5]. 2. Justification (justification): This parameter provides a short (typically one-sentence) explanation required when requesting approval for escalated or altered permissions [6][1]. It serves as a record for the user to understand why a specific command necessitates bypassing standard security constraints [6]. Important Implementation Notes: - Policy Interaction: The runtime behavior depends heavily on the active approval_policy [3]. For instance, when the policy is set to OnRequest, the model is expected to provide these parameters to request necessary escalations [6]. - Granular Limitations: Under the Granular approval policy, the runtime may reject direct shell-based requests for sandbox_permissions (such as require_escalated) if the policy configuration does not allow them [3][7]. In such cases, the recommended path is often to use a dedicated request_permissions tool rather than attempting to pass these parameters directly within a standard shell tool call [3]. - Security Semantics: Technical implementations treat sandbox_permissions as a per-command override rather than a general permissions configuration [5]. Any explicit override is generally considered "prompt-worthy" by the execution policy when operating in restricted sandbox modes [5].

💡 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].

CodeRabbit CLI review --agent --committed --uncommitted --include-untracked --base-commit documentation
💡 Result:
The CodeRabbit CLI cr review command is used to perform AI-driven code reviews directly from your terminal. When using the flags provided in your query, here is how they function: --agent: Configures the CLI to output structured JSON instead of the default plain-text format [1][2]. This is designed for agent-driven workflows and integrations with other tools that require machine-readable data [3][4]. --committed: Restricts the review scope to only include committed changes in your Git repository [1][2]. --uncommitted: Restricts the review scope to include only staged changes and unstaged edits to tracked files [1][2]. --include-untracked: Expands the review scope to include non-ignored files that have not yet been added to Git, in addition to the tracked changes [1][2]. --base-commit: While not a standard top-level flag in the primary CLI documentation, the cr review command supports comparing against a specific commit hash [5][6]. Based on specialized skills documentation, you can use --base-commit <commit-hash> to compare the current state against a specific historical commit [5][6]. General Usage Notes: - The CLI must be run from within an initialized Git repository [2][7]. - By default, cr review analyzes all tracked changes (committed, staged, and unstaged) [1][2]. - If multiple scope flags are combined (e.g., --uncommitted and --include-untracked), the CLI will analyze the union of those files [3][4]. - You can use the short alias cr instead of the full coderabbit command [3][4]. Example: To run an agent-compatible review of all uncommitted changes (including untracked files), you would use: cr review --agent --uncommitted --include-untracked [3]

Agent Skills specification SKILL.md current specification
💡 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].

AGENTS.md open format specification current documentation
💡 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].

CodeRabbit declared host agents code-reviewer.md current public documentation
💡 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"

The term base-commit is not a standard native Git command or parameter. It is a configuration option used by specific third-party development tools, such as the CodeRabbit CLI, to define a specific commit on a branch to use as a reference point for comparisons or reviews [1]. In these contexts, it serves to identify the starting point or base for evaluating changes [1].

github coderabbitai cursor-plugin skills code-review SKILL.md selector validation --committed --uncommitted
💡 Result:
The CodeRabbit Cursor plugin and its associated SKILL.md configurations for code review do not use a command-line flag system specifically named --committed or --uncommitted for selector validation within the plugin's local development or validation scripts [1]. Instead, the plugin architecture and the CodeRabbit CLI operate as follows: 1. Plugin Validation: The repository for the CodeRabbit Cursor plugin includes a local validation script (typically executed via npm test) that checks manifest fields, paths, metadata, and the validity of SKILL.md frontmatter [1]. This script ensures the plugin structure conforms to Cursor's requirements but is distinct from the operational flags used during live code reviews [1]. 2. Code Review Operation: When running CodeRabbit reviews, particularly within Cursor or via the CLI, the --uncommitted flag is used as a functional parameter for the review command (e.g., coderabbit review --uncommitted), not as part of a SKILL.md selector or a validation-specific filter [2]. Using --uncommitted instructs CodeRabbit to review staged and tracked local edits rather than committed branch changes, allowing for immediate feedback during agentic development [2]. 3. Skill Configuration: CodeRabbit SKILL.md files define agent capabilities and triggers (e.g., coderabbit.?review) using standardized frontmatter [3][4]. These files do not include internal logic for filtering commit status (like committed vs. uncommitted) within the SKILL.md itself; rather, they serve as the interface through which the agent invokes the CodeRabbit CLI [3][5]. For developers working on these plugins, the correct process is to run the repository's provided validation scripts for structural integrity [1] and to use the appropriate CLI flags at runtime for controlling the scope of the code review [2].

Before: a sandbox-only preflight could miss host credentials and look unauthenticated, generic elevation prose did not reliably trigger Codex's runtime parameter, and the instructions contained stale scope/severity guidance.
After: the trusted CLI checks its own credential store through one exact host-executed status call. Review calls use the same narrow boundary. Unknown never becomes a login prompt, raw credentials are never retrieved or relayed, and unsupported paths or outputs fail closed.
