What problem does it solve? Editing CLI configuration files is risky when you do not know which host you are on or which schema applies. This Skill resolves the active host and its configuration first, then applies only the requested changes while preserving sandbox, credential, and approval boundaries. ## Core Features & Use Cases - Host Resolution: Identifies whether the current environment is Codex or a Cursor-compatible host before touching any config file. - Schema-Aware Editing: Uses current Codex config.toml documentation for Codex and the legacy Cursor cli-config.json schema only for verified Cursor hosts. - Boundary Preservation: Changes only the requested settings and leaves unrelated configuration, sandbox rules, credentials, and approval modes untouched. - Use Case: A user asks to enable network access in the sandbox. The Skill verifies the host, locates the resolved config path, updates only the sandbox networkAccess field, and keeps all other settings intact. ## Quick Start Update my CLI configuration to enable vim mode, making sure to detect whether I am on Codex or Cursor first.
