# Hermes /loop: recurring agent wake-ups with real stop conditions

▶

Chapters / key moments
(click to jump — plays here on the page)

Hermes has shipped `/loop`, a timer-driven wake-up for work that depends on time rather than on you. You set the prompt once; the agent wakes on a recurring timer, re-reads the current state of the world fresh each tick, does the work, reports back, and goes quiet until the next one. The interesting part is the stop conditions — a fixed tick count, a natural-language condition, a judge model that evaluates after every wake-up, or letting the agent decide for itself when the job is done. Fahd Mirza runs the whole thing locally against Qwen 3.8 27B served by llama.cpp, with no API key involved.

## Step-by-Step Breakdown

1. **Update Hermes first — the feature is very recent**
 Run `hermes update` before anything else. He is explicit that `/loop` is a recent addition and that an installation even slightly behind on commits simply will not have it. This is the single most likely reason the walkthrough fails to reproduce.
2. **Create a profile for the loop**
 He creates a profile called `loop demo`. Provider is set to **custom**, pointed at the local llama.cpp server, with the local Qwen 3.8 27B model and a current working directory. Nothing here is loop-specific yet — it is an ordinary Hermes profile.
3. **Add the loop settings to the profile config**
 Creating the profile writes a config file, and the loop behaviour is configured in its own section of that file (see [Loop settings](#loop-settings) below). This is where the pacing and the hard stop live — the interval floor, the maximum number of wake-ups, and the self-paced backoff range.
4. **Build something that actually changes state on its own schedule**
 To demo a loop honestly you need a moving target. He writes a small shell script that simulates a deployment pipeline walking through four stages — `queued`, `building`, `deploying`, `live` — with a 60-second `sleep` between each, writing the current stage to a status file. The loop watches that file.
5. **Start the fake deployer, then start Hermes alongside it**
 The script runs in one terminal; Hermes is launched in parallel in another. The agent is not driving the deployment — it is observing something external, which is precisely the case `/loop` exists for.
6. **Give the loop one prompt with an embedded stop condition**
 The instruction is: check the status file every 30 seconds and report the stage; when the stage reads `live`, end the reply with `loop complete`. That trailing token is the stop condition — Hermes confirms the loop is set, tells you when the first wake-up will fire, and then runs unattended.
7. **Walk away**
 Five wake-ups later the loop closes itself. Each tick it read the status file fresh, reported the stage in one line, and went back to sleep: queued → building → deploying → live → `loop complete`. No terminal was touched after the initial prompt.

## Loop settings shown in the profile config

These are the four knobs he walks through on screen. The behaviour is described exactly as demonstrated; check `hermes`'s own documentation for the precise key spellings before you paste anything into a config file.

- **Minimum interval** — a floor on firing frequency. Set to 30 seconds in the demo, meaning the loop will never wake more often than that no matter what the prompt asks for.
- **Maximum ticks** — the hard stop. Set to 100 wake-ups; on hitting it the loop pauses itself rather than running forever. This is your runaway-cost backstop.
- **Backoff floor and ceiling** — the self-paced range. It starts checking every 30 seconds, and if nothing is changing it slows itself down to once every 2 minutes. A watcher on a quiet target costs progressively less.

## The four stop conditions

This is the part that makes `/loop` more than a timer:

- **A fixed number of runs** — run exactly N times, then stop.
- **A natural-language condition** — "stop when the deploy is live". This is what the demo uses, expressed as a token the agent emits when it judges the condition met.
- **A judge model** — a separate model evaluates after every single wake-up whether the job is done.
- **Agent's own judgement** — let the agent decide when it is finished. This is the presenter's stated preference.

## Gotchas & Caveats

- **An out-of-date install silently lacks the feature.** `/loop` is recent enough that this is the expected failure. Run `hermes update` first and confirm the version.
- **The read tool deduplicates unchanged content.** On the fifth wake-up the agent noticed it was re-reading a file whose content had not changed and switched, on its own, to checking the file's modification time with `stat` instead. Worth knowing if you are building a watcher whose target changes rarely — reading a file is not a reliable change signal, and a timestamp check is the sturdier probe.
- **A loop watching nothing still costs tokens.** The backoff ceiling is what bounds that, and the maximum-ticks value is what stops a forgotten loop from running indefinitely. Set both deliberately.

## /loop vs /goal vs cron — the distinction that matters

All three look similar and solve genuinely different problems. This is the clearest articulation of the difference we have seen:

- **/loop is timer-driven.** Use it when something external is changing on its own schedule and you want the agent watching it.
- **/goal is judge-driven.** Use it when you have a specific objective and want the agent hammering on it until it is done.
- **cron is for work that must survive your terminal closing.** It runs outside any session entirely.

His rule of thumb: **watching something → loop. Fixing something → goal. Scheduling something unattended → cron.**

## Commands & Code Shown

### `hermes update`

```
hermes update
```

**Purpose:** Pulls Hermes up to the latest commits.

**When to use:** Before attempting `/loop` at all. The feature is new enough that a slightly stale install will not expose it, and the failure mode is a missing command rather than a helpful error.

### `/loop`

```
/loop
```

**Purpose:** Starts a recurring, timer-driven wake-up that re-reads state fresh on each tick and stops on the condition you specify.

**When to use:** Watching an external process you do not control — a deployment, a build queue, a file that a different system writes.

### `stat`

```
stat <file>
```

**Purpose:** Reads a file's metadata, including modification time.

**When to use:** As a change probe when the read tool's deduplication makes repeated file reads unreliable — which is exactly what the agent worked out for itself mid-run.

## Key Takeaways

- **The stop condition is the feature.** A recurring timer is trivial; a recurring timer that knows when to stop — by tick count, by natural-language condition, by judge model, or by the agent's own call — is what turns polling into delegation.
- **Fresh reads every tick are the point.** Each wake-up re-reads the current state of the world rather than reasoning over a stale context, which is what makes it usable for genuinely time-dependent work.
- **It runs fully local.** The entire demo is Qwen 3.8 27B on llama.cpp with no API key — see [best free models for Hermes](https://openclawdatabase.com/hermes/free-models/) and [Hermes setup](https://openclawdatabase.com/hermes/setup/).
- **Pick the right primitive.** Watching → `/loop`; fixing → `/goal`; must survive the terminal closing → cron.
- **Bound it before you walk away.** Maximum ticks and the backoff ceiling are the two settings that keep an unattended loop from becoming an unattended bill.
