Explain work, a system or a situation to Sergio in plain words with real names, so he understands it on one read. Use when he asks to explain like a 5yo, says eli5, or says he does not understand what was done or where things stand.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Running in Codex
This is the Codex copy of this skill. Read the rest of it with these translations:
- Agents launched in parallel: spawn each one with `spawn_agent` before waiting on any, then collect the
results with `wait_agent`. Tell every agent you spawn not to spawn agents of its own. If subagents are
unavailable, run each lane yourself, one after another.
- "Your default model" and "your strongest model": spawn the agent with an `agent_type` whose role file in
`~/.codex/agents/` sets `model` and `model_reasoning_effort`. An agent without a role runs on the
session's model.
- A slash command such as `/name`: mention the skill as `$name`.
- This repository's hooks and `.claude/` paths are for Claude Code only, and nothing here installs a Codex
hook. A loop runs one pass per invocation, saves its state and reports how to resume.
- `CLAUDE.md`: also read `AGENTS.md`, which is the file Codex loads.
# eli5
Sergio reads this when he has lost the thread. He wants to understand, not to be impressed. Simplify the telling, never the claims: every sentence stays true to the code, the calls and the messages, and the words get shorter, not the facts.

The line at the top of this page pins the label git:20261006.717893e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
