Codex — Delegate coding to OpenAI Codex CLI (features, PRs)
Codex — Delegate coding to OpenAI Codex CLI (features, PRs)
Start with meaning, then move to detail.
This lesson explains Codex — Delegate coding to OpenAI Codex CLI (features, PRs) as part of extending Hermes and connecting external tools. You will learn what it does, when it matters, and the smallest safe test that proves it works.
If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?
For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.
For advanced readers, inspect Skill metadata, Reference: full SKILL.md, When to use, then verify failure modes and version compatibility.
Complete installation and one successful task before adding new capabilities.
A clear outcome before you read.
- Understand Codex — Delegate coding to OpenAI Codex CLI (features, PRs) without assumed prior knowledge.
- Separate the source description from what still needs testing in your environment.
- Read the first command and identify its inputs and outputs before copying it.
Short definitions before the details.
- Gateway
- The process that connects Hermes to channels such as Telegram or Discord and routes messages.
- Skill
- An instruction bundle that teaches Hermes a repeatable workflow without necessarily adding an external service.
- Automation
- Running work later or repeatedly with explicit success and failure conditions.

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.
