 **Filesystem as interface** — if you know how to operate a filesystem, you know how to operate ollie. Any tool that reads and writes files — `ed`, `vim`, Python, `cat`, a shell script — is already a fully capable ollie client. No SDK, no API, no protocol to learn.

 **Crash resiliency** — Memory (`m/`) is written to persistent storage outside the session. If a session crashes or is killed mid-task, it is not lost — a fresh session picks up where the previous one left off.

 **Sub-agents** — `subagent_spawn` implements fork-join over the `b/` namespace: spawn N specialized agents with a shared prompt, wait for all to complete, collect results in submission order. For heterogeneous parallel delegation (N agents, N different prompts), use a `{parallel: [...]}` stage in `execute_code` — each parallel step calls `subagent_spawn` with a different prompt, all running concurrently.
 
-**Environment injection is a front-end concern** — Because the daemon is a long-running process separate from the front-end, any environment variable the session needs (e.g. `SUPERPOWERD_SESSION_TOKEN`) must be injected by the front-end via `s/{id}/env`. This is not a serious limitation, but it makes front-end setup slightly more involved: tools like `superpowers` require the front-end itself to be launched inside the privileged context (`superpowers run-session ollie-tui ...`), rather than simply having the variable present in the daemon's environment.

 **No MCP** — MCP (Model Context Protocol) adds a JSON-RPC client, transport layer, initialization handshake, and subprocess lifecycle management to do what `execute_code {tool: "name"}` already does. Every MCP server can be replaced by a tool script in `t/` and a skill in `sk/`. `x/elevate` proved this: it replaced an MCP server with a shell script. See [doc/NO_MCP.md](NO_MCP.md) for the full justification.

 The 9P filesystem is the lowest level interface to ollie. All interfaces are simply wrappers around filesystem operations, and `s/sh` is the standard chat interface. Other front-ends:
 
-- **[ollie-tui](https://github.com/lneely/ollie-tui)** — a fancier terminal UI for the less curmudgeonly
 - **[ellie](https://github.com/lneely/ollie-el)** — `ellie.el` is the Emacs front-end, just wire it into your `init.el` and `M-x ellie`
 - **Web UI** — browser-based UI; requires `ollie-httpgw` (see above)
