The places are those the agents' documentation or source gives, not all checked by running them. +### OpenCode 1 and 2 + +OpenCode 2 is another program (`@opencode/cli`) that may answer to the same `opencode` command. It runs one background server per user, which owns its configuration, so what a session's environment says (a config's provider and model, enowX's guide and tools) is ignored once that server runs. So enowX starts `opencode` with `--standalone` when it reports version 2 or later, giving the session a private server and leaving the user's alone; 1.x doesn't start with that flag. A session's config holds the provider in both versions' forms. A plugin named in the user's own OpenCode config loads as it does anywhere: enowX adds none. A session started this way doesn't show in other clients of the shared server. + +### The block in a project + +The agents with no other way get a block at the top of the project's `AGENTS.md`, or its `CLAUDE.md` if that is the one it has, between `` and ``. It says where the guide is, by no path of this machine's, and applies only when `ENOWX_SESSION` is set. The rest of the file stays as it was, and an update rewrites the block rather than adding another. **On by default; a tracked file shows it in `git diff`, and it would be committed with it.** A new `AGENTS.md` it makes goes in `.git/info/exclude` instead. `enowx-app project settings --guide-block off` (`[guide] block = false` in `.enowx.toml`) takes it out.
