codex-cli

使用 Codex CLI 执行代码审查、分析与技术研究。当用户说出“Codex”或“/Codex”，或提出深度代码审查、全代码库分析、漏洞调查、重构建议、基础设施/K8s/Terraform 审查、CI/CD 流水线分析，或需要超越简单 grep/读取操作的技术研究时，即可触发此技能。

description: Execute code review, analysis, and technical research using Codex CLI.

Command Template

bash
codex exec \
  --model {MODEL} \
  --config model_reasoning_effort="{LEVEL}" \

Parameter notes:

  • •gpt-5.3-codex for code tasks, gpt-5.2 for general/infra tasks
  • •Default sandbox to read-only; use workspace-write only when editing files
  • •danger-full-access (network access) requires explicit user confirmation
  • •Add --full-auto only with workspace-write
  • •Append 2>/dev/null only if user requests hidden output

Prompt Format

code
TASK: {clear, specific action}
CONTEXT: {tech stack, environment, constraints}
FOCUS: {specific areas to examine}
OUTPUT: {desired format and detail level}

Rules

  • •Always include --skip-git-repo-check, --model, --config model_reasoning_effort, --sandbox
  • •Never use danger-full-access without user confirmation
  • •Never use --full-auto with read-only

Session Continuation

Resume previous session (inherits model and sandbox settings):

bash
codex exec --skip-git-repo-check resume --last
# Or with additional instructions:
echo "{instructions}" | codex exec --skip-git-repo-check resume --last
