## Ideas
|
||||
|
||||
### Automation & Scripting
|
||||
|
||||
**Scripting and automation** — shell scripts that submit prompts, poll `state` until idle, then read `chat` for the result. No SDK, no HTTP client, just file I/O. Works in any language that can write to a file.
|
||||
|
||||
**Multiplexing sessions** — run several agents in parallel, each in their own session directory, and fan work out to them from a shell script. Coordinate by watching their `state` files.
|
||||
|
||||
**Hooks and watchers** — poll `state` in a loop to trigger actions when the agent finishes, or use `tail -f chat` to react to new output. Build lightweight event-driven pipelines with standard shell tools.
|
||||
|
||||
### Tooling & Integration
|
||||
|
||||
**Unix tools** — pipe `chat` into `grep`, `awk`, `sed`. Diff two sessions' outputs. Log conversations with `cp`. Search history across sessions with `grep -r`.
|
||||
|
||||
**Editor integration** — any editor that can read/write files gets agent access for free. In `acme` or `sam`, you write to `prompt` and read back `chat` with no plugin required. Fits naturally into the Plan 9 workflow.
|
||||
|
||||
**Lightweight TUI alternatives** — `watch cat state` as a status bar, `tail -f chat` in one pane, prompt submission in another. Compose a working interface entirely from standard tools.
|
||||
|
||||
### Network & Remote Access
|
||||
|
||||
**Remote access** — 9P is a network protocol. Export the namespace over the network and access agent sessions from another machine using the same file interface, with no additional daemon or API layer.
|
||||
|
||||
### Multi-Agent Workflows
|
||||
|
||||
Each session exposes a `reply` file containing only the assistant text from the most recently completed turn. Writing to `prompt` clears `reply` as a side-effect. Together these make agent-to-agent handoffs expressible as plain file operations — no message queue, no orchestration framework, no shared memory.
|
||||
|
||||
A shell script moves text between sessions. The agents communicate only through what the script explicitly passes between them, so information flow is fully under your control. Each agent can use a different backend, model, or tool configuration. A human can intervene at any point by writing directly to a session's `prompt`.
|
||||
|
||||
#### Example: develop → review → test
|
||||
|
||||
Three sessions with specialized agent configs run a feedback loop. The reviewer ends its response with `LGTM` (proceed) or `PTAL` (revise). The tester ends with `Approved` (done) or `Rejected` (revise). A shell script reads the verdict with `grep` and routes accordingly.
|
||||
|
||||
```sh
|
||||
#!/bin/sh
|
||||
workdir=${1:?usage: $0 <workdir>}
|
||||
cd ~/mnt/ollie
|
||||
|
||||
# Count existing sessions so we can identify the newly created ones by offset.
|
||||
n=$(ls s/ | wc -l)
|
||||
|
||||
echo "new agent=developer workdir=$workdir" > ctl
|
||||
echo "new agent=reviewer workdir=$workdir" > ctl
|
||||
echo "new agent=tester workdir=$workdir" > ctl
|
||||
|
||||
dev=$(ls s/ | sort | sed -n "$((n+1))p")
|
||||
rev=$(ls s/ | sort | sed -n "$((n+2))p")
|
||||
tst=$(ls s/ | sort | sed -n "$((n+3))p")
|
||||
|
||||
wait_reply() {
|
||||
while [ "$(wc -c < s/$1/reply)" -eq 0 ]; do sleep 1; done
|
||||
}
|
||||
|
||||
echo "implement a function that parses a JSON config file" > s/$dev/prompt
|
||||
|
||||
while true; do
|
||||
wait_reply $dev
|
||||
code=$(cat s/$dev/reply)
|
||||
|
||||
# review phase
|
||||
printf "Review the following code. End your response with LGTM if it is ready, or PTAL if it needs revision.\n\n%s" "$code" > s/$rev/prompt
|
||||
wait_reply $rev
|
||||
|
||||
if ! grep -qi "LGTM" s/$rev/reply; then
|
||||
{ echo "revise this code based on the feedback below."
|
||||
echo "--- code ---"; echo "$code"
|
||||
echo "--- feedback ---"; cat s/$rev/reply
|
||||
} > s/$dev/prompt
|
||||
continue
|
||||
fi
|
||||
|
||||
# test phase
|
||||
printf "Test the following code. End your response with Approved if all tests pass, or Rejected if they do not.\n\n%s" "$code" > s/$tst/prompt
|
||||
wait_reply $tst
|
||||
|
||||
if grep -qi "Approved" s/$tst/reply; then
|
||||
echo "done."
|
||||
echo "$code"
|
||||
break
|
||||
fi
|
||||
|
||||
{ echo "fix the failures reported below."
|
||||
echo "--- code ---"; echo "$code"
|
||||
echo "--- test report ---"; cat s/$tst/reply
|
||||
} > s/$dev/prompt
|
||||
done
|
||||
```
|
||||
|
||||
Each agent only sees what the script explicitly sends it. Each can use a different backend, model, or tool configuration. A human can intervene at any point by writing directly to a session's `prompt`. The boundary between fully automated and human-in-the-loop is just whether the script pauses to ask.
|
||||
|
||||
### Sub-Agents
|
||||
|
||||
A session can spawn ephemeral child sessions to handle a focused task, then tear them down when done. The parent uses `execute_code` to write `new` to `ctl`, send an initial context and task to the child's `prompt`, poll until `reply` is ready, read the result, and write `kill <id>` to `ctl`. From the child's perspective it is just a normal session; it has no knowledge of its own ephemerality.
|
||||
|
||||
**Sub-agents as function calls** — the parent primes the child with exactly the context it needs (excerpts from its own `chat`, relevant beads, local file contents) and receives a single focused reply. Failures are isolated; a child that errors or stalls can be killed and retried without affecting the parent. The pattern composes naturally: a sub-agent can itself spawn sub-agents, building a call tree bounded only by the number of sessions open at once.
|
||||
|
||||
`spawn_subagents.py` reads a JSON spec from stdin, fans out the work concurrently, and returns a JSON array of results — a single `execute_tool` call from the parent's perspective. Note: this requires adding Python language support to `execute_code`, `execute_tool`, and `execute_pipe`, which is low effort.
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
"""spawn_subagents.py — fan out tasks to ephemeral olliesrv sub-agents.
|
||||
|
||||

print()
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
|
||||
|
||||
The parent agent constructs the spec and makes a single tool call:
|
||||
|
||||
```json
|
||||
[
|
||||
{ "task": "review this code for correctness", "agent": "reviewer", "context": "..." },
|
||||
{ "task": "check this code for security issues", "agent": "security", "context": "..." }
|
||||
]
|
||||
```
|
||||
|
||||
Results come back as:
|
||||
|
||||
```json
|
||||
[
|
||||
{ "agent": "reviewer", "reply": "..." },
|
||||
{ "agent": "security", "reply": "..." }
|
||||
]
|
||||
```
|
||||
|
||||
### Self-Generating Workflows
|
||||
|
||||
Since agents have access to `execute_code`, a session can write and execute a workflow script without any human involvement. Given a task and knowledge of the filesystem layout, an agent can decompose the work, spawn sessions, write the coordination script, and run it — all in a single turn. The README you are reading is essentially its system prompt. Conductor functionality, for free.
|
||||
|
||||
### Persistent Memory
|
||||
|
||||
**Task tracking** — Agent sessions are ephemeral by nature: context windows fill, processes crash, work gets lost. [9beads](https://github.com/lneely/9beads) addresses this by exposing a structured, version-controlled task database as a 9P filesystem. Any session can read the task list, claim work, track dependencies, and mark completion through ordinary file operations. If a session is interrupted, another can pick up exactly where it left off. Task lists are scoped per-project, keeping them focused and bounded. Combined with olliesrv, agents get both a communication surface and a memory layer, with no special integration required between them.
