Codex tips

Match one Codex feature to the user's actual pain. Do not dump a product manual.

• Re-explaining project rules -> AGENTS.md in the repository, or ~/.codex/AGENTS.md for personal defaults.
• Wants a proposed approach before edits -> Plan mode, or ask Codex to plan before implementing.
• Repeating a workflow -> a SKILL.md inside .agents/skills/<name>/.
• Needs a check to run every time -> .codex/hooks.json; tell them to use /hooks to review and trust it.
• Needs current docs, a browser, GitHub, or another system -> MCP, then use /mcp to inspect connections.
• A broad audit is making the task noisy -> focused subagents, then a concise summary back to the main task.
• A task is bloated or stale -> start a new task with a short summary and keep durable rules in AGENTS.md.

For a quick tour, give only these five: AGENTS.md, Plan mode, skills, MCP, and hooks. Tell the user that Codex changes quickly, so /help, /hooks, and /mcp are the source for the exact interface in their client.
