"Still using Codex as a chat tool?"
"Codex all-around agent handbook. Many people don't lack the ability to use Codex — they're still treating it as a chat tool. The real way to use it is to treat Codex as an agent that enters the project: read context first, then give a plan, then execute, then verify."

Install deep-skill-finder once, then let Codex discover Skills
Turning Codex from a chat tool into a project partner comes down to project context, knowledge base, and efficiency tips — Meyo has Skills for all three. You don't need to find them one by one. After installing deep-skill-finder, Codex will automatically search Meyo's 50,000+ Skill library and recommend matching workflows for your task. You focus on what to do; let the Agent handle Skill discovery.
Install the deep-skill-finder Skill: download the Skill archive from https://www.meyo.life/skill-finder, extract it to your local Skill directory, and enable it.

Frequently asked questions
Q: What's the fundamental difference between using Codex as an agent vs. a chat tool?
A: In chat mode, you ask and Codex answers — it doesn't proactively read project context. In agent mode, Codex first scans project structure, reads config files, understands task boundaries, then proposes a plan and executes. The difference: an agent has project-situational awareness; it doesn't answer in a vacuum.
Q: What files do I need to prepare for project context management?
A: The core trio: project README (background and goals), AGENTS.md (behavior rules), and pitfall log (historical experience). After installing coding-agent-common, the Agent helps you auto-generate templates for these files — you just fill in the content.
Q: After setting up a knowledge base, can Codex automatically retrieve project history?
A: Yes. The core of knowledge base setup is structuring experience (like Obsidian notes, pitfall logs). Codex automatically retrieves relevant experience before executing tasks. But retrieval quality depends on how structured the knowledge base is — use tags and categories, don't just pile up text.
Q: Are efficiency tips universal? Do different projects need different Skill combos?
A: Efficiency tips have universal parts (like sub-agent delegation, batch execution) and project-specific parts. Universal Skills like codex-sub-agents fit all projects; project-specific Skills depend on your tech stack. Start with universal Skills as a foundation, then add specific ones as needed.
Q: How steep is the learning curve from chat mode to agent mode?
A: Not steep. You only need to do three things: create an AGENTS.md with rules, create a project background doc, and install a Skill that can delegate tasks. 7 days is enough to switch from chat to agent mode. The Meyo community has complete onboarding templates — scan the QR to join Discord and get them.
Q: Are these Skills cross-Agent compatible? Do they work with Claude Code / Cursor?
A: They all work. These Skills are cross-Agent neutral designs — Claude Code / Codex / Cursor / WorkBuddy can all install them. The installation is identical — download from meyo.life/community/skills, extract to your Agent's Skill directory.
