codex exec review against uncommitted changes, a specific commit, or a base branch, with optional custom focus prompts. - Options, Idea, and Plan Review: Builds self-contained heredoc prompts from conversation context so Codex can evaluate trade-offs, risks, and sequencing. - Reliability Safeguards: Forces -m gpt-5.4 and model_reasoning_effort=xhigh regardless of user config, and disables configured MCP servers to avoid mid-run disconnections. - Use Case: After drafting an execution plan for a new feature, type /codex review plan to have GPT-5.4 critique completeness, sequencing, and risks before implementation begins. ## Quick Start Ask the assistant to run /codex review code to have Codex review your uncommitted changes with xhigh reasoning.High-intent search queries and answers about installing and using this skill.
Run codex exec review --uncommitted with explicit flags -m gpt-5.4 and -c model_reasoning_effort=xhigh. The review subcommand automatically diffs against git, and you can append a prompt describing the code's intent for more accurate feedback.
codex exec review is the dedicated subcommand for git-based code review, supporting flags like --uncommitted, --commit, and --base. Plain codex exec is used for freeform prompts such as reviewing plans, options, or ideas passed via heredoc.
Codex sessions with xhigh reasoning run 60-180 seconds or longer, and MCP connections frequently disconnect mid-run, causing the entire response to be lost. Disable each configured server with -c mcp_servers.<name>.enabled=false, referencing only servers that exist in ~/.codex/config.toml.
Yes. Pass the plan, options, or idea in a heredoc prompt to codex exec with the model and reasoning flags. Include context such as relevant file paths or requirements, and ask Codex to evaluate trade-offs, risks, sequencing, and missing steps.
This happens when a command references an MCP server that does not exist in ~/.codex/config.toml. Check the [mcp_servers] section of the config and only disable servers that are actually configured.
