First steps into actual context engineering

Hi fellas. I'm just happy to share that I started to use Agents.md! I've been using for a few days both Opus 4.6 (by default in Claude Code) with my 20$ plan and Codex 5.3 included in my 10$ github copilot pro plan.

But I had two major problems: \- [Claude.md](http://Claude.md) instructions weren't shared with Codex \- I was running out of usage due to lack of context between sessions.

I asked claude to explain the problem and build the files to fix this. So now I'm using [Agents.md](http://Agents.md) as the only "truth source" (term that I learned today), and symlinks are created pointing to the other agents context .md's (claude.md, .cursorrules, .github-copilot-instructions.md... etc).

I also jumped onto my first skill creation. Since I \*knew\* I was doing things wrong, I asked for an auto-audit to look for improvement areas, specially regarding the repository structure, the architecture, the quality of context, security flaws, global tasks performed to purse a certain (main) goal, etc. That reads all that and gives you some results, X over 60 points.

Does this ring a bell for anybody? =D Also: any tips?
