The agent is the harness
Layer 02. The agent that loads the context every session, and the rails around the model that make it safe to use.
What makes an agent effective inside a company is not which model answers. It is what the agent knows before it starts, what it is allowed to do, and what gets recorded when it acts. Those live in files around the model. The model is a setting.
The rails
| Rail | What it does | Page |
|---|---|---|
| Operating manual | AGENTS.md says how the agent works, what it may do, and how you like to work. Every host reads it at session start. | The agent home |
| Permission rails | Allow and deny lists, a sandboxed shell, secrets in a store the agent's own tools cannot read. | Configuration |
| Hooks | Session start loads the context, session end captures it, a guard checks every shell command. Skills advise; hooks enforce. | Hooks |
| Audit trail | Every session captured to a dated file, every task change threaded, the folder under git. | Tasks |
| Observability | The dashboard, the session radar, briefings and pulses. | Daily rhythm |
| Host-neutral | One home works from Claude Code or Codex. What a host provides, and what a new one needs. | Hosts |
How a session runs
Launch from the home. The SessionStart hook loads the identity stack, the wiki index, active memory, the task board, today's date, and the tail of the last session. You type. Skills run when you invoke them; tools do I/O and return prompts for your own session to think with, so nothing bills a metered key. On exit the transcript is captured for the next compile. Your first session walks through one.
Work, not chats
Tasks are one markdown file each with frontmatter, a checklist, and a thread. Projects group them. Parallel work happens in worktrees so agents never collide on one repo. The architecture page shows how the host, the plugin, and the brain fit.
