## 1. Prerequisites
|
||||
|
||||
| Requirement | Minimum | Recommended |
|
||||
|-------------|---------|-------------|
|
||||
| OS | Ubuntu 22.04 LTS | Ubuntu 24.04 LTS |
|
||||
| RAM | 512 MB | 2 GB |
|
||||
| CPU | 1 vCPU | 2 vCPU |
|
||||
| Disk | 5 GB | 20 GB |
|
||||
| Python | 3.11 | 3.12 |
|
||||
| Node.js | 18 | 20 |
|
||||
| Git | any | any |
|
||||
|
||||
**Optional but recommended:**
|
||||
- Docker Engine ≥ 24 + Compose plugin (for containerised deployment)
|
||||
- `curl`, `jq` (for health-check scripting)
|
||||
|
||||
---
|
||||
|
||||
## 2. Environment Setup
|
||||
|
||||
### 2a. Create a dedicated system user (bare-metal deployments)
|
||||
|
||||
```bash
|
||||
sudo useradd -m -s /bin/bash hermes
|
||||
sudo su - hermes
|
||||
```
|
||||
|
||||
### 2b. Install Hermes
|
||||
|
||||
```bash
|
||||
# Official one-liner installer
|
||||
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
|
||||
|
||||
# Reload PATH so `hermes` is available
|
||||
source ~/.bashrc
|
||||
```
|
||||
|
||||
The installer places:
|
||||
- The agent code at `~/.local/lib/python3.x/site-packages/` (pip editable install)
|
||||
- The `hermes` entry point at `~/.local/bin/hermes`
|
||||
- Default config directory at `~/.hermes/`
|
||||
|
||||
### 2c. Verify installation
|
||||
|
||||
```bash
|
||||
hermes --version
|
||||
hermes doctor
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 3. Secret Injection
|
||||
|
||||
**Rule: secrets never live in the repository. They live only in `~/.hermes/.env`.**
|
||||
|
||||
```bash
|
||||
# Copy the template (do NOT edit the repo copy)
|
||||
cp /path/to/hermes-agent/.env.example ~/.hermes/.env
|
||||
chmod 600 ~/.hermes/.env
|
||||
|
||||
# Edit with your preferred editor
|
||||
nano ~/.hermes/.env
|
||||
```
|
||||
|
||||
### Minimum required keys
|
||||
|
||||
| Variable | Purpose | Where to get it |
|
||||
|----------|---------|----------------|
|
||||
| `OPENROUTER_API_KEY` | LLM inference | https://openrouter.ai/keys |
|
||||
| `TELEGRAM_BOT_TOKEN` | Telegram gateway | @BotFather on Telegram |
|
||||
|
||||
### Optional but common keys
|
||||
|
||||
| Variable | Purpose |
|
||||
|----------|---------|
|
||||
| `DISCORD_BOT_TOKEN` | Discord gateway |
|
||||
| `SLACK_BOT_TOKEN` + `SLACK_APP_TOKEN` | Slack gateway |
|
||||
| `EXA_API_KEY` | Web search tool |
|
||||
| `FAL_KEY` | Image generation |
|
||||
| `ANTHROPIC_API_KEY` | Direct Anthropic inference |
|
||||
|
||||
### Pre-flight validation
|
||||
|
||||
Before starting the stack, run:
|
||||
|
||||
```bash
|
||||
python scripts/deploy-validate --check-ports --skip-health
|
||||
```
|
||||
|
||||
This catches missing keys, placeholder values, and misconfigurations without touching running services.
|
||||
|
||||
---
|
||||
|
||||
## 4. Installation
|
||||
|
||||
### 4a. Clone the repository (if not using the installer)
|
||||
|
||||
```bash
|
||||
git clone https://forge.alexanderwhitestone.com/Timmy_Foundation/hermes-agent.git
|
||||
cd hermes-agent
|
||||
pip install -e ".[all]" --user
|
||||
npm install
|
||||
```
|
||||
|
||||
### 4b. Run the setup wizard
|
||||
|
||||
```bash
|
||||
hermes setup
|
||||
```
|
||||
|
||||
The wizard configures your LLM provider, messaging platforms, and data directory interactively.
|
||||
|
||||
---
|
||||
|
||||
## 5. Starting the Stack
|
||||
|
||||
### Bare-metal (foreground — useful for first run)
|
||||
|
||||
```bash
|
||||
# Agent + gateway combined
|
||||
hermes gateway start
|
||||
|
||||
# Or just the CLI agent (no messaging)
|
||||
hermes
|
||||
```
|
||||
|
||||
### Bare-metal (background daemon)
|
||||
|
||||
```bash
|
||||
hermes gateway start &
|
||||
echo $! > ~/.hermes/gateway.pid
|
||||
```
|
||||
|
||||
### Via systemd (recommended for production)
|
||||
|
||||
See [Section 12](#12-systemd-deployment).
|
||||
|
||||
### Via Docker Compose
|
||||
|
||||
See [Section 11](#11-docker-compose-deployment).
|
||||
|
||||
---
|
||||
|
||||
## 6. Health Checks
|
||||
|
||||
### 6a. API server liveness probe
|
||||
|
||||
The API server (enabled via `api_server` platform in gateway config) exposes `/health`:
|
||||
|
||||
```bash
|
||||
curl -s http://127.0.0.1:8642/health | jq .
|
||||
```
|
||||
|
||||
Expected response:
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "ok",
|
||||
"platform": "hermes-agent",
|
||||
"version": "0.5.0",
|
||||
"uptime_seconds": 123,
|
||||
"gateway_state": "running",
|
||||
"platforms": {
|
||||
"telegram": {"state": "connected"},
|
||||
"discord": {"state": "connected"}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| Field | Meaning |
|
||||
|-------|---------|
|
||||
| `status` | `"ok"` — HTTP server is alive. Any non-200 = down. |
|
||||
| `gateway_state` | `"running"` — all platforms started. `"starting"` — still initialising. |
|
||||
| `platforms` | Per-adapter connection state. |
|
||||
|
||||
### 6b. Gateway runtime status file
|
||||
|
||||
```bash
|
||||
cat ~/.hermes/gateway_state.json | jq '{state: .gateway_state, platforms: .platforms}'
|
||||
```
|
||||
|
||||
### 6c. Deploy-validate script
|
||||
|
||||
```bash
|
||||
python scripts/deploy-validate
|
||||
```
|
||||
|
||||
Runs all checks and prints a pass/fail summary. Exit code 0 = healthy.
|
||||
|
||||
### 6d. systemd health
|
||||
|
||||
```bash
|
||||
systemctl status hermes-gateway
|
||||
journalctl -u hermes-gateway --since "5 minutes ago"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 7. Stop / Restart Procedures
|
||||
|
||||
### Graceful stop
|
||||
|
||||
```bash
|
||||
# systemd
|
||||
sudo systemctl stop hermes-gateway
|
||||
|
||||
# Docker Compose
|
||||
docker compose -f deploy/docker-compose.yml down
|
||||
|
||||
# Process signal (if running ad-hoc)
|
||||
kill -TERM $(cat ~/.hermes/gateway.pid)
|
||||
```
|
||||
|
||||
### Restart
|
||||
|
||||
```bash
|
||||
# systemd
|
||||
sudo systemctl restart hermes-gateway
|
||||
|
||||
# Docker Compose
|
||||
docker compose -f deploy/docker-compose.yml restart hermes
|
||||
|
||||
# Ad-hoc
|
||||
hermes gateway start --replace
|
||||
```
|
||||
|
||||
The `--replace` flag removes stale PID/lock files from an unclean shutdown before starting.
|
||||
|
||||
---
|
||||
|
||||
## 8. Zero-Downtime Restart
|
||||
|
||||
Hermes is a stateful long-running process (persistent sessions, active cron jobs). True zero-downtime requires careful sequencing.
|
||||
|
||||
### Strategy A — systemd rolling restart (recommended)
|
||||
|
||||
systemd's `Restart=on-failure` with a 5-second back-off ensures automatic recovery from crashes. For intentional restarts, use:
|
||||
|
||||
```bash
|
||||
sudo systemctl reload-or-restart hermes-gateway
|
||||
```
|
||||
|
||||
`hermes-gateway.service` uses `TimeoutStopSec=30` so in-flight agent turns finish before the old process dies.
|
||||
|
||||
> **Note:** Active messaging conversations will see a brief pause (< 30 s) while the gateway reconnects to platforms. The session store is file-based and persists across restarts — conversations resume where they left off.
|
||||
|
||||
### Strategy B — Blue/green with two HERMES_HOME directories
|
||||
|
||||
For zero-downtime where even a brief pause is unacceptable:
|
||||
|
||||
```bash
|
||||
# 1. Prepare the new environment (different HERMES_HOME)
|
||||
export HERMES_HOME=/home/hermes/.hermes-green
|
||||
hermes setup # configure green env with same .env
|
||||
|
||||
# 2. Start green on a different port (e.g. 8643)
|
||||
API_SERVER_PORT=8643 hermes gateway start &
|
||||
|
||||
# 3. Verify green is healthy
|
||||
curl -s http://127.0.0.1:8643/health | jq .gateway_state
|
||||
|
||||
# 4. Switch load balancer (nginx/caddy) to port 8643
|
||||
|
||||
# 5. Gracefully stop blue
|
||||
kill -TERM $(cat ~/.hermes/.hermes/gateway.pid)
|
||||
```
|
||||
|
||||
### Strategy C — Docker Compose rolling update
|
||||
|
||||
```bash
|
||||
# Pull the new image
|
||||
docker compose -f deploy/docker-compose.yml pull hermes
|
||||
|
||||
# Recreate with zero-downtime if you have a replicated setup
|
||||
docker compose -f deploy/docker-compose.yml up -d --no-deps hermes
|
||||
```
|
||||
|
||||
Docker stops the old container only after the new one passes its healthcheck.
|
||||
|
||||
---
|
||||
|
||||
## 9. Rollback Procedure
|
||||
|
||||
### 9a. Code rollback (pip install)
|
||||
|
||||
```bash
|
||||
# Find the previous version tag
|
||||
git log --oneline --tags | head -10
|
||||
|
||||
# Roll back to a specific tag
|
||||
git checkout v0.4.0
|
||||
pip install -e ".[all]" --user --quiet
|
||||
|
||||
# Restart the gateway
|
||||
sudo systemctl restart hermes-gateway
|
||||
```
|
||||
|
||||
### 9b. Docker image rollback
|
||||
|
||||
```bash
|
||||
# Pull a specific version
|
||||
docker pull ghcr.io/nousresearch/hermes-agent:v0.4.0
|
||||
|
||||
# Update docker-compose.yml image tag, then:
|
||||
docker compose -f deploy/docker-compose.yml up -d
|
||||
```
|
||||
|
||||
### 9c. State / data rollback
|
||||
|
||||
The data directory (`~/.hermes/` or the Docker volume `hermes_data`) contains sessions, memories, cron jobs, and the response store. Back it up before every update:
|
||||
|
||||
```bash
|
||||
# Backup (run BEFORE updating)
|
||||
tar czf ~/backups/hermes_data_$(date +%F_%H%M).tar.gz ~/.hermes/
|
||||
|
||||
# Restore from backup
|
||||
sudo systemctl stop hermes-gateway
|
||||
rm -rf ~/.hermes/
|
||||
tar xzf ~/backups/hermes_data_2026-04-06_1200.tar.gz -C ~/
|
||||
sudo systemctl start hermes-gateway
|
||||
```
|
||||
|
||||
> **Tested rollback**: The rollback procedure above was validated in staging on 2026-04-06. Data integrity was confirmed by checking session count before/after: `ls ~/.hermes/sessions/ | wc -l`.
|
||||
|
||||
---
|
||||
|
||||
## 10. Database / State Migrations
|
||||
|
||||
Hermes uses two persistent stores:
|
||||
|
||||
| Store | Location | Format |
|
||||
|-------|----------|--------|
|
||||
| Session store | `~/.hermes/sessions/*.json` | JSON files |
|
||||
| Response store (API server) | `~/.hermes/response_store.db` | SQLite WAL |
|
||||
| Gateway state | `~/.hermes/gateway_state.json` | JSON |
|
||||
| Memories | `~/.hermes/memories/*.md` | Markdown files |
|
||||
| Cron jobs | `~/.hermes/cron/*.json` | JSON files |
|
||||
|
||||
### Migration steps (between versions)
|
||||
|
||||
1. **Stop** the gateway before migrating.
|
||||
2. **Backup** the data directory (see Section 9c).
|
||||
3. **Check release notes** for migration instructions (see `RELEASE_*.md`).
|
||||
4. **Run** `hermes doctor` after starting the new version — it validates state compatibility.
|
||||
5. **Verify** health via `python scripts/deploy-validate`.
|
||||
|
||||
There are currently no SQL migrations to run manually. The SQLite schema is
|
||||
created automatically on first use with `CREATE TABLE IF NOT EXISTS`.
|
||||
|
||||

|
||||
|
||||
## 11. Docker Compose Deployment
|
||||
|
||||
### First-time setup
|
||||
|
||||
```bash
|
||||
# 1. Copy .env.example to .env in the repo root
|
||||
cp .env.example .env
|
||||
nano .env # fill in your API keys
|
||||
|
||||
# 2. Validate config before starting
|
||||
python scripts/deploy-validate --skip-health
|
||||
|
||||
# 3. Start the stack
|
||||
docker compose -f deploy/docker-compose.yml up -d
|
||||
|
||||
# 4. Watch startup logs
|
||||
docker compose -f deploy/docker-compose.yml logs -f
|
||||
|
||||
# 5. Verify health
|
||||
curl -s http://127.0.0.1:8642/health | jq .
|
||||
```
|
||||
|
||||
### Updating to a new version
|
||||
|
||||
```bash
|
||||
# Pull latest image
|
||||
docker compose -f deploy/docker-compose.yml pull
|
||||
|
||||
# Recreate container (Docker waits for healthcheck before stopping old)
|
||||
docker compose -f deploy/docker-compose.yml up -d
|
||||
|
||||
# Watch logs
|
||||
docker compose -f deploy/docker-compose.yml logs -f --since 2m
|
||||
```
|
||||
|
||||
### Data backup (Docker)
|
||||
|
||||
```bash
|
||||
docker run --rm \
|
||||
-v hermes_data:/data \
|
||||
-v $(pwd)/backups:/backup \
|
||||
alpine tar czf /backup/hermes_data_$(date +%F).tar.gz /data
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 12. systemd Deployment
|
||||
|
||||
### Install unit files
|
||||
|
||||
```bash
|
||||
# From the repo root
|
||||
sudo cp deploy/hermes-agent.service /etc/systemd/system/
|
||||
sudo cp deploy/hermes-gateway.service /etc/systemd/system/
|
||||
|
||||
sudo systemctl daemon-reload
|
||||
|
||||
# Enable on boot + start now
|
||||
sudo systemctl enable --now hermes-gateway
|
||||
|
||||
# (Optional) also run the CLI agent as a background service
|
||||
# sudo systemctl enable --now hermes-agent
|
||||
```
|
||||
|
||||
### Adjust the unit file for your user/paths
|
||||
|
||||
Edit `/etc/systemd/system/hermes-gateway.service`:
|
||||
|
||||
```ini
|
||||
[Service]
|
||||
User=youruser # change from 'hermes'
|
||||
WorkingDirectory=/home/youruser
|
||||
EnvironmentFile=/home/youruser/.hermes/.env
|
||||
ExecStart=/home/youruser/.local/bin/hermes gateway start --replace
|
||||
```
|
||||
|
||||
Then:
|
||||
|
||||
```bash
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl restart hermes-gateway
|
||||
```
|
||||
|
||||
### Verify
|
||||
|
||||
```bash
|
||||
systemctl status hermes-gateway
|
||||
journalctl -u hermes-gateway -f
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 13. Monitoring & Logs
|
||||
|
||||
### Log locations
|
||||
|
||||
| Log | Location |
|
||||
|-----|----------|
|
||||
| Gateway (systemd) | `journalctl -u hermes-gateway` |
|
||||
| Gateway (Docker) | `docker compose logs hermes` |
|
||||
| Session trajectories | `~/.hermes/logs/session_*.json` |
|
||||
| Deploy events | `~/.hermes/logs/deploy.log` |
|
||||
| Runtime state | `~/.hermes/gateway_state.json` |
|
||||
|
||||
### Useful log commands
|
||||
|
||||
```bash
|
||||
# Last 100 lines, follow
|
||||
journalctl -u hermes-gateway -n 100 -f
|
||||
|
||||
# Errors only
|
||||
journalctl -u hermes-gateway -p err --since today
|
||||
|
||||
# Docker: structured logs with timestamps
|
||||
docker compose -f deploy/docker-compose.yml logs --timestamps hermes
|
||||
```
|
||||
|
||||
### Alerting
|
||||
|
||||
Add a cron job on the host to page you if the health check fails:
|
||||
|
||||
```bash
|
||||
# /etc/cron.d/hermes-healthcheck
|
||||
* * * * * root curl -sf http://127.0.0.1:8642/health > /dev/null || \
|
||||
echo "Hermes unhealthy at $(date)" | mail -s "ALERT: Hermes down" ops@example.com
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 14. Security Checklist
|
||||
|
||||
- [ ] `.env` has permissions `600` and is **not** tracked by git (`git ls-files .env` returns nothing).
|
||||
- [ ] `API_SERVER_KEY` is set if the API server is exposed beyond `127.0.0.1`.
|
||||
- [ ] API server is bound to `127.0.0.1` (not `0.0.0.0`) unless behind a TLS-terminating reverse proxy.
|
||||
- [ ] Firewall allows only the ports your platforms require (no unnecessary open ports).
|
||||
- [ ] systemd unit uses `NoNewPrivileges=true`, `PrivateTmp=true`, `ProtectSystem=strict`.
|
||||
- [ ] Docker container has resource limits set (`deploy.resources.limits`).
|
||||
- [ ] Backups of `~/.hermes/` are stored outside the server (e.g. S3, remote NAS).
|
||||
- [ ] `hermes doctor` returns no errors on the running instance.
|
||||
- [ ] `python scripts/deploy-validate` exits 0 after every configuration change.
|
||||

|
||||
|
||||
## 15. Troubleshooting
|
||||
|
||||
### Gateway won't start
|
||||
|
||||
```bash
|
||||
hermes gateway start --replace # clears stale PID files
|
||||
|
||||
# Check for port conflicts
|
||||
ss -tlnp | grep 8642
|
||||
|
||||
# Verbose logs
|
||||
HERMES_LOG_LEVEL=DEBUG hermes gateway start
|
||||
```
|
||||
|
||||
### Health check returns `gateway_state: "starting"` for more than 60 s
|
||||
|
||||
Platform adapters take time to authenticate (especially Telegram + Discord). Check logs for auth errors:
|
||||
|
||||
```bash
|
||||
journalctl -u hermes-gateway --since "2 minutes ago" | grep -i "error\|token\|auth"
|
||||
```
|
||||
|
||||
### `/health` returns connection refused
|
||||
|
||||
The API server platform may not be enabled. Verify your gateway config (`~/.hermes/config.yaml`) includes:
|
||||
|
||||
```yaml
|
||||
gateway:
|
||||
platforms:
|
||||
- api_server
|
||||
```
|
||||
|
||||
### Rollback needed after failed update
|
||||
|
||||
See [Section 9](#9-rollback-procedure). If you backed up before updating, rollback takes < 5 minutes.
|
||||
|
||||
### Sessions lost after restart
|
||||
|
||||
Sessions are file-based in `~/.hermes/sessions/`. They persist across restarts. If they are gone, check:
|
||||
|
||||
```bash
|
||||
ls -la ~/.hermes/sessions/
|
||||
# Verify the volume is mounted (Docker):
|
||||
docker exec hermes-agent ls /opt/data/sessions/
|
||||
```

|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Allegro executed 7 tasks across infrastructure, contracting, audits, and security. Ezra shipped PR #131, filed formalization audit #132, delivered quarterly report #133, and self-assigned issues #134–#138. All wizard activity mapped below.
|
||||
|
||||

||||
|------|-------------|--------|
|
||||
| 1 | Roll Call / Infrastructure Map | ✅ Complete |
|
||||
| 2 | Dark industrial anthem (140 BPM, Suno-ready) | ✅ Complete |
|
||||
| 3 | Operation Get A Job — 7-file contracting playbook pushed to `the-nexus` | ✅ Complete |
|
||||
| 4 | Formalization audit filed ([the-nexus #893](https://forge.alexanderwhitestone.com/Timmy_Foundation/the-nexus/issues/893)) | ✅ Complete |
|
||||
| 5 | GrepTard Memory Report — PR #525 on `timmy-home` | ✅ Complete |

> **Audience:** Forge wizards joining the hermes-agent project

|
||||
## The One Rule
|
||||
|
||||
**Read the actual state before acting.**
|
||||
|
||||
Before touching any service, config, or codebase: `ps aux | grep hermes`, `cat ~/.hermes/gateway_state.json`, `curl http://127.0.0.1:8642/health`. The forge punishes assumptions harder than it rewards speed. Evidence always beats intuition.
|
||||
|
||||
---
|
||||
|
||||
## First 15 Minutes on a New System
|
||||
|
||||
```bash
|
||||
# 1. Validate your environment
|
||||
python wizard-bootstrap/wizard_bootstrap.py
|
||||
|
||||
# 2. Check what is actually running
|
||||
ps aux | grep -E 'hermes|python|gateway'
|
||||
|
||||
# 3. Check the data directory
|
||||
ls -la ~/.hermes/
|
||||
cat ~/.hermes/gateway_state.json 2>/dev/null | python3 -m json.tool
|
||||
|
||||
# 4. Verify health endpoints (if gateway is up)
|
||||
curl -sf http://127.0.0.1:8642/health | python3 -m json.tool
|
||||
|
||||
# 5. Run the smoke test
|
||||
source venv/bin/activate
|
||||
python -m pytest tests/ -q -x --timeout=60 2>&1 | tail -20
|
||||
```
|
||||
|
||||
Do not begin work until all five steps return clean output.

||||

## Import Chain — Know It, Respect It

||||
|

The dependency order is load-bearing. Violating it causes silent failures:

||||
|
||||
```
|
||||
tools/registry.py ← no deps; imported by everything
|
||||
↑
|
||||
tools/*.py ← each calls registry.register() at import time
|
||||
↑
|
||||
model_tools.py ← imports registry; triggers tool discovery
|
||||
↑
|
||||
run_agent.py / cli.py / batch_runner.py
|
||||
```
|
||||
|
||||
**If you add a tool file**, you must also:
|
||||
1. Add its import to `model_tools.py` `_discover_tools()`
|
||||
2. Add it to `toolsets.py` (core or a named toolset)
|
||||
|
||||
Missing either step causes the tool to silently not appear — no error, just absence.

## The Five Profile Rules
|
||||
|
||||
Hermes supports isolated profiles (`hermes -p myprofile`). Profile-unsafe code has caused repeated bugs. Memorize these:
|
||||
|
||||
| Do this | Not this |
|
||||
|---------|----------|
|
||||
| `get_hermes_home()` | `Path.home() / ".hermes"` |
|
||||
| `display_hermes_home()` in user messages | hardcoded `~/.hermes` strings |
|
||||
| `get_hermes_home() / "sessions"` in tests | `~/.hermes/sessions` in tests |
|
||||
|
||||
Import both from `hermes_constants`. Every `~/.hermes` hardcode is a latent profile bug.
|
||||
|
||||

|
||||
|
||||
## Prompt Caching — Do Not Break It
|
||||
|
||||
The agent caches system prompts. Cache breaks force re-billing of the entire context window on every turn. The following actions break caching mid-conversation and are forbidden:
|
||||
|
||||
- Altering past context
|
||||
- Changing the active toolset
|
||||
- Reloading memories or rebuilding the system prompt
|
||||
|
||||
The only sanctioned context alteration is the context compressor (`agent/context_compressor.py`). If your feature touches the message history, read that file first.
|
||||

||||
|
||||
## Adding a Slash Command (Checklist)
|
||||
|
||||
Four files, in order:
|
||||
|
||||
1. **`hermes_cli/commands.py`** — add `CommandDef` to `COMMAND_REGISTRY`
|
||||
2. **`cli.py`** — add handler branch in `HermesCLI.process_command()`
|
||||
3. **`gateway/run.py`** — add handler if it should work in messaging platforms
|
||||
4. **Aliases** — add to the `aliases` tuple on the `CommandDef`; everything else updates automatically
|
||||
|
||||
All downstream consumers (Telegram menu, Slack routing, autocomplete, help text) derive from `COMMAND_REGISTRY`. You never touch them directly.
|
||||
|
||||

|
||||
|
||||
## Tool Schema Pitfalls
|
||||
|
||||
**Do NOT cross-reference other toolsets in schema descriptions.**
|
||||
Writing "prefer `web_search` over this tool" in a browser tool's description will cause the model to hallucinate calls to `web_search` when it's not loaded. Cross-references belong in `get_tool_definitions()` post-processing blocks in `model_tools.py`.
|
||||
|
||||
**Do NOT use `\033[K` (ANSI erase-to-EOL) in display code.**
|
||||
Under `prompt_toolkit`'s `patch_stdout`, it leaks as literal `?[K`. Use space-padding instead: `f"\r{line}{' ' * pad}"`.
|
||||
|
||||
**Do NOT use `simple_term_menu` for interactive menus.**
|
||||
It ghosts on scroll in tmux/iTerm2. Use `curses` (stdlib). See `hermes_cli/tools_config.py` for the pattern.

## Health Check Anatomy
|
||||
|
||||
A healthy instance returns:
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "ok",
|
||||
"gateway_state": "running",
|
||||
"platforms": {
|
||||
"telegram": {"state": "connected"}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| Field | Healthy value | What a bad value means |
|
||||
|-------|--------------|----------------------|
|
||||
| `status` | `"ok"` | HTTP server down |
|
||||
| `gateway_state` | `"running"` | Still starting or crashed |
|
||||
| `platforms.<name>.state` | `"connected"` | Auth failure or network issue |
|
||||
|
||||
`gateway_state: "starting"` is normal for up to 60 s on boot. Beyond that, check logs for auth errors:
|
||||
|
||||
```bash
|
||||
journalctl -u hermes-gateway --since "2 minutes ago" | grep -i "error\|token\|auth"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Gateway Won't Start — Diagnosis Order
|
||||
|
||||
1. `ss -tlnp | grep 8642` — port conflict?
|
||||
2. `cat ~/.hermes/gateway.pid` → `ps -p <pid>` — stale PID file?
|
||||
3. `hermes gateway start --replace` — clears stale locks and PIDs
|
||||
4. `HERMES_LOG_LEVEL=DEBUG hermes gateway start` — verbose output
|
||||
5. Check `~/.hermes/.env` — missing or placeholder token?
|
||||
|
||||

|
||||
|
||||
## Before Every PR
|
||||
|
||||
```bash
|
||||
source venv/bin/activate
|
||||
python -m pytest tests/ -q # full suite: ~3 min, ~3000 tests
|
||||
python scripts/deploy-validate # deployment health check
|
||||
python wizard-bootstrap/wizard_bootstrap.py # environment sanity
|
||||
```
|
||||
|
||||
All three must exit 0. Do not skip. "It works locally" is not sufficient evidence.
|
||||

||||
## Session and State Files
|
||||
|
||||
| Store | Location | Notes |
|
||||
|-------|----------|-------|
|
||||
| Sessions | `~/.hermes/sessions/*.json` | Persisted across restarts |
|
||||
| Memories | `~/.hermes/memories/*.md` | Written by the agent's memory tool |
|
||||
| Cron jobs | `~/.hermes/cron/*.json` | Scheduler state |
|
||||
| Gateway state | `~/.hermes/gateway_state.json` | Live platform connection status |
|
||||
| Response store | `~/.hermes/response_store.db` | SQLite WAL — API server only |
|
||||
|
||||
All paths go through `get_hermes_home()`. Never hardcode. Always backup before a major update:
|
||||
|
||||
```bash
|
||||
tar czf ~/backups/hermes_$(date +%F_%H%M).tar.gz ~/.hermes/
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Writing Tests
|
||||
|
||||
```bash
|
||||
python -m pytest tests/path/to/test.py -q # single file
|
||||
python -m pytest tests/ -q -k "test_name" # by name
|
||||
python -m pytest tests/ -q -x # stop on first failure
|
||||
```
|
||||
|
||||
**Test isolation rules:**
|
||||
- `tests/conftest.py` has an autouse fixture that redirects `HERMES_HOME` to a temp dir. Never write to `~/.hermes/` in tests.
|
||||
- Profile tests must mock both `Path.home()` and `HERMES_HOME`. See `tests/hermes_cli/test_profiles.py` for the pattern.
|
||||
- Do not mock the database. Integration tests should use real SQLite with a temp path.
