# agent-procs
Concurrent process runner for AI agents. Processes run in a background daemon and persist across CLI invocations.
## Install
```
cargo install agent-procs
```
## Quick start
```bash
# Start a process
agent-procs run "npm run dev" --name server
# Wait for it to be ready
agent-procs wait server --until "Listening on" --timeout 30
# Check output
agent-procs logs server --tail 50
# See what's running
agent-procs status
# Stop it
agent-procs stop server
```
## Config file
Create an `agent-procs.yaml` to manage multiple processes together:
```yaml
session: myproject # optional — isolates this project's processes
proxy: true # optional — enables reverse proxy
proxy_port: 9095 # optional — pin proxy to a specific port
processes:
db:
cmd: docker compose up postgres
ready: "ready to accept connections"
api:
cmd: ./start-api-server
cwd: ./backend
env:
DATABASE_URL: postgres://localhost:5432/mydb
ready: "Listening on :8080"
port: 8080
depends_on: [db]
```
Processes start in dependency order; independent ones run concurrently.
```bash
agent-procs up # start all
agent-procs up --only db,api # start specific ones
agent-procs down # stop all
```
### Field reference
**Per-process fields:**
| `cmd` | yes | Shell command to execute |
| `cwd` | no | Working directory (relative to config file location) |
| `env` | no | Environment variables (key: value map) |
| `ready` | no | Stdout pattern that signals the process is ready |
| `depends_on` | no | List of process names that must be ready first |
| `port` | no | Port number — injected as `PORT` and `HOST=127.0.0.1` env vars |
**Top-level fields:**
| `session` | no | Session name (overridden by `--session` CLI flag) |
| `proxy` | no | Enable reverse proxy (default: false) |
| `proxy_port` | no | Pin proxy to a specific port (default: auto-assign from 9090-9190) |
## Reverse proxy
Give processes stable named URLs instead of port numbers. Opt-in via `proxy: true` in config or `--proxy` on the CLI.
```bash
$ agent-procs up
Proxy listening on http://localhost:9090
started api (http://api.localhost:9090)
started web (http://web.localhost:9090)
```
- Processes without an explicit `port` get one auto-assigned (4000-4999 range)
- `PORT` and `HOST=127.0.0.1` are injected into the process env (user env takes precedence)
- Each session gets its own proxy port, so two projects can both have `api` without conflict
Ad-hoc usage without a config file:
```bash
agent-procs run "node server.js" --name api --port 3001 --proxy
# → http://api.localhost:9090
```
## Commands
| `run <cmd> [--name N] [--port P] [--proxy]` | Spawn a background process |
| `stop <name>` | Stop a process |
| `stop-all` | Stop all processes |
| `restart <name>` | Restart a process |
| `status [--json]` | Show all process statuses |
| `logs <name> [--tail N] [--follow] [--stderr] [--all]` | View process output |
| `wait <name> --until <pattern> [--regex] [--timeout N]` | Wait for output pattern |
| `wait <name> --exit [--timeout N]` | Wait for process to exit |
| `up [--only X,Y] [--config path] [--proxy]` | Start from config file |
| `down` | Stop config-managed processes |
| `session list` | List active sessions |
| `session clean` | Remove stale sessions |
| `ui` | Open terminal UI |
| `completions <shell>` | Generate shell completions (bash, zsh, fish, powershell) |
## Sessions
Use `--session` to isolate process groups (e.g. per-project):
```bash
agent-procs --session projectA run "make serve" --name app
agent-procs --session projectB run "make serve" --name app
agent-procs --session projectA status # only shows projectA's processes
```
## Architecture
The CLI communicates with a per-session background daemon over a Unix domain socket. The daemon manages process lifecycles, captures stdout/stderr to log files, and handles wait conditions. The daemon auto-starts on first use and exits when all processes are stopped.
## Exit codes
| 0 | Success |
| 1 | Error (timeout, connection failure, unexpected response) |
| 2 | No logs found for target process |
