Codex App-Server Runtime (optional)
Codex App-Server Runtime (optional)
Start with meaning, then move to detail.
This lesson explains Codex App-Server Runtime (optional) as part of Hermes internals and extension points. 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 Why, What tools the model actually has, 1. Codex's built-in toolset (always on), then verify failure modes and version compatibility.
Know Python, Git, and basic project structure before changing code.
A clear outcome before you read.
- Understand Codex App-Server Runtime (optional) 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.
- MCP
- A standard way to expose external tools, resources, and services to an agent.
- Provider
- The service that runs or provides access and authentication to a model.
- Tool
- A structured action the agent can call to read or change something.
- Automation
- Running work later or repeatedly with explicit success and failure conditions.
What does the source say, and in what order?
- 01Why
Start here to understand the core idea or structure.
- 02What tools the model actually has
Read this after the foundation, then connect it to the previous step.
- 031. Codex's built-in toolset (always on)
Read this after the foundation, then connect it to the previous step.
- 042. Native Codex plugins (auto-migrated from your codex plugin install)
Read this after the foundation, then connect it to the previous step.
- 053. Hermes tool callback (MCP server, registered in ~/.codex/config.toml)
Read this after the foundation, then connect it to the previous step.
- 06What's NOT available on this runtime
Read this after the foundation, then connect it to the previous step.
- 07Workflow features (/goal, kanban, cron)
Read this after the foundation, then connect it to the previous step.
- 08/goal (the Ralph loop)
Read this after the foundation, then connect it to the previous step.
- 09Kanban (multi-agent worktree dispatch)
Read this after the foundation, then connect it to the previous step.
- 10Cron jobs
Finish here to verify the result and special cases.
Copy only after you understand the effect.
npm i -g @openai/codex
codex --version # 0.130.0 or newercodex login # writes tokens to ~/.codex/auth.jsoncodex plugin marketplace add openai-curated
# then via codex's TUI, install Linear / GitHub / Gmail / etc.Read the first command and identify its inputs and outputs before copying it.
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.
