Usage

Server

Start and stop

olliesrv                # start the server (foreground)
# Stop by sending SIGTERM or via the supervisor (e.g. rc-service ollie stop)

TCP listener

To also accept connections over TCP (e.g. for remote access):

olliesrv -tcp :9564

Debug logging

Log level is controlled by OLLIE_LOG (default: warn). Set to debug for verbose output:

OLLIE_LOG=debug olliesrv

Valid levels: debug, info, warn, error.

Security and sandboxing

toolsrv applies the configured policy directly through native Landlock in a short-lived child helper; it does not depend on an external sandbox executable. On Linux, the helper creates and restricts a Landlock ruleset before executing the tool. Use yolo=true only for explicit development cases where enforcement should be disabled.

o — Terminal CLI

o is a multi-call shell script that wraps the 9P namespace into a human-friendly interface. Installed to ~/.local/bin/o by make install-data.

Quick start

o myproj/default new                  # create session + agent
o myproj/default tui                  # launch the tmux TUI

Or without the TUI:

o myproject/default prompt        # interactive prompt REPL (one terminal)
o myproject/default read chat     # stream chat output (another terminal)

o tui — tmux + shell commands

acme — Plan 9 editor

Context model

Context is determined by the first argument — not by environment variables:

o <cmd>                     Root level (no context)
o <session> <cmd>           Session level
o <session>/<agent> <cmd>   Agent level

The slash in <session>/<agent> disambiguates session-only from session+agent. o ls lists the root of the ollie namespace; o with no arguments prints help.

Commands

Command	Context	Description
o ls	root	List sessions, models, backends
o generate <prompt>	root	One-shot generation (no session needed)
o <sess>/<agent> new [cwd]	agent	Create session (if needed) + agent
o <sess> ls	session	List session contents
o <sess> ctl <cmd>	session	Session control
o <sess>/<agent> prompt	agent	Interactive multi-line prompt REPL
o <sess>/<agent> tui	agent	Launch tmux TUI
o <sess>/<agent> ctl <cmd>	agent	Agent control (stop, compact, model, etc.)
o <sess>/<agent> log [-n N]	agent	Show last N lines of agent log
o read [-l] <path>	any	Read a file (-l: loop)
o write <path> [data]	any	Write to a file (args or stdin)
o env	any	Print export statements for current context
o help	any	Show help

Path resolution

When you supply a context, o sets a prefix:

• Session: session/<sess>
• Agent: session/<sess>/agent/<agent>

Paths given to read, write, and ls are resolved relative to this prefix. A leading / escapes the prefix and addresses the root namespace directly:

Invocation	Resolves to
o myproj/coding read chat	session/myproj/agent/coding/chat
o myproj/coding read cfg	session/myproj/agent/coding/cfg
o myproj read env	session/myproj/env
o myproj/coding read /models	models (root)
o myproj/coding ls /bypass	bypass (root)
o read models	models (no context, no prefix)

The leading slash is necessary when you want to access root-level paths (like models, backends, bypass/) while in session or agent context. Without it, the path is concatenated with the context prefix.

Prompt REPL

o <session>/<agent> prompt is an interactive multi-line REPL:

$ o myproj/coding prompt
[myproj/coding]
Type . on a blank line to send, Ctrl+D to exit.
/ prefix runs ctl: /stop, /compact, /model X, /inject X
!q exits the TUI.

> write a fibonacci function in python
  and include a test case
  .

Type your prompt across multiple lines, then send with . on its own line. Any agent ctl command works as a slash command — the / prefix is stripped and the rest is sent to ctl:

Command	Description
/stop	Interrupt running agent
/compact	Compact context window
/clear	Clear history
/kill	Kill the agent
/model [X]	Show or switch model
/models	List available models
/backend	Show current backend
/agent [X]	Show or switch agent profile
/name [X]	Show or set agent display name
/cwd [X]	Show or change working directory
/inject X	Inject text into context (alias: /i)
/tools	List loaded tools
/tool_load X	Load a tool
/tool_unload X	Unload a tool
/peeradd X	Add a bidirectional peer link
/peerdel X	Remove a bidirectional peer link
/peers	List current peers
!q	Kill the tmux TUI session and exit

Piped input is also supported:

echo "explain this error" | o myproj/coding prompt
cat file.go | o myproj/coding write prompt

One-shot generation

No session or agent needed — o generate sends a prompt and returns a response:

o generate "explain monads in one sentence"
cat error.log | o generate   # pipe content as the prompt
echo "write a haiku about filesystems" | o generate | wc -w

o tui — tmux Terminal UI

o <session>/<agent> tui composes o read chat and o prompt into a single tmux layout — two shell commands in two panes, with agent state in the tmux status bar:

Usage

o myproj/coding tui

1. Creates a tmux session named o-<session>.
2. Two panes:
   • Pane 0 (top, 80%): streams chat output (log tail + live read chat).
   • Pane 1 (bottom, 20%): o prompt — multi-line REPL (/ prefix runs ctl commands).
3. A background process subscribes to the agent's state events via echo "session.{s}.agent.{a}.state" | ollie-9p rdwrs event and updates the tmux status bar on each state transition.
4. Focuses the prompt pane and attaches.

No polling. Each read blocks until data arrives. The status bar updates on every state transition via the event stream — zero CPU when idle.

tmux tips

• Ctrl+b ; — toggle between last two panes (fast prompt ↔ tail switch)
• Ctrl+b z — zoom any pane to full screen
• Ctrl+b [ — scroll mode (arrow keys, q to exit)
• Ctrl+b d — detach (session keeps running, reattach with tmux attach -t o-<session>)

---

o env — Context export

o env prints export statements for the current context. This is useful for other tools (raw ollie-9p commands, scripts) that need to know which session and agent are being addressed:

eval $(o myproj/coding env)
# exports OLLIE_SESSION=myproj OLLIE_AGENT=coding
ollie-9p read session/$OLLIE_SESSION/agent/$OLLIE_AGENT/stats

Note: o itself does not read these environment variables — it determines context purely from its positional arguments.
