description: >
  Standard Hermes configuration template for Syslog Solution LLC agents.
  Enforces shared infrastructure setup (Firecrawl, SearXNG, local models,
  RA-H OS MCP) while keeping agent-specific API keys and model choices.
  Updated 2026-06-30: new LiteLLM keys, nginx routing, router back online.

## Agent Keys (LiteLLM — Current 2026-06-30)

Each agent has a unique LiteLLM API key. Keys are stored in LiteLLM's PostgreSQL DB.
The env var `LITELLM_API_KEY` is set in `/etc/environment` on each agent host.
Sub-agent profiles inherit auth from the main config — no separate keys needed.

| Agent | Key | Host | SSH | Sub-Agents |
|-------|-----|------|-----|-----------|
| Tanko | `sk-3ZsdWJbbNSo9zSnJN2OsJw` | 192.168.68.122 | jerome@.122 | — |
| Mumuni | `sk-XY2aUfvy2BIs6kp1ZPh6VA` | 192.168.68.123 | root@.123 | 6 profiles ✱ |
| Abiba | `sk-kxbPgbnV2Zkn6TKQbAEcEg` | 192.168.68.24 | local | — |
| Koby | `sk-wb86PvcZXWkjShAIBxrpDg` | ? | Zulip | — |
| Koonimo | `sk-Prx_vRXYb2VEzDmhPCbNeg` | 192.168.68.114 | Zulip | — |
| Kagenz0 | `sk-Dh4CDkaHebMLEp8qqq20qA` | ? | Zulip | — |

✱ Mumuni sub-agents: syslog-code, syslog-devops, syslog-email, syslog-research,
  syslog-review, syslog-writer — all at `/root/.hermes/profiles/<name>/config.yaml`

## Infrastructure Stack

| Component | Endpoint | Purpose |
|---|---|---|
| Firecrawl | `http://192.168.68.7:3002/` | Web content extraction |
| SearXNG | `http://storepve:8888` | Privacy-respecting web search |
| LiteLLM | `http://192.168.68.116/v1` | Unified model gateway (via nginx) |
| LiteLLM (NetBird) | `https://litellm.sysloggh.net/v1` | Alternative (may have 502 issues) |
| RA-H OS MCP | `http://192.168.68.65:3100/mcp` | Knowledge graph bridge |
| Context7 MCP | `http://localhost:8079/mcp` | Documentation queries |

## API Key Rules

- `api_key_env: LITELLM_API_KEY` — Use env var for main model auth (preferred)
- `api_key: ''` — Sub-agents leave empty to inherit from main config's custom_provider
- `api_key: sk-...` — Hardcoded key only as fallback when env var not possible
- Set `LITELLM_API_KEY` in `/etc/environment` on each host
- Sub-agents NEVER get their own key — they share the host agent's key
- Restart Hermes after updating `/etc/environment`

### Sub-Agent Profiles (Mumuni pattern)

Mumuni has 6 sub-agent profiles in `/root/.hermes/profiles/<name>/config.yaml`:

```
profiles/
├── syslog-code/config.yaml      # Code generation
├── syslog-devops/config.yaml     # DevOps/infrastructure
├── syslog-email/config.yaml      # Email processing
├── syslog-research/config.yaml   # Research & analysis
├── syslog-review/config.yaml     # Code review
└── syslog-writer/config.yaml     # Content writing
```

Sub-agent profile rules:
1. **`api_key` must be empty** — `api_key: ''` or omitted entirely
2. **`base_url` must be empty** — inherits from main config's custom_provider
3. **`provider` is `auto` or `harness`** — routes through the shared LiteLLM gateway
4. **`model` is agent-specific** — each sub-agent can have its own default model
5. **Auxiliary tasks** (vision, compression, etc.) also leave `api_key` empty
6. **Never hardcode a key** in sub-agent profiles

This ensures all 6 sub-agents use the same LiteLLM key set in `/etc/environment`.
When the key is rotated, only the env var needs updating — all 7 configs (main + 6 subs)
work immediately after restart.

## Template — Required Sections

```yaml
# ─── Model Selection ───
model:
  default: <agent_model>          # e.g., qwen3.6-27B-code, syslog-auto
  provider: harness
  base_url: http://192.168.68.116/v1
  api_key_env: LITELLM_API_KEY    # Set in /etc/environment

fallback_providers:
  provider: deepseek
  model: deepseek-chat
  api_key_env: DEEPSEEK_API_KEY

# ─── Web Stack (SHARED INFRA — DO NOT CHANGE) ───

  backend: firecrawl
  search_backend: searxng
  extract_backend: firecrawl
  firecrawl:
    base_url: http://192.168.68.7:3002/

# ─── MCP Servers (SHARED INFRA) ───

    max_concurrency: 3
    api_key_env: LITELLM_API_KEY

  - name: harness
    model: <agent_model>
    base_url: http://192.168.68.116/v1
    api_key_env: LITELLM_API_KEY
    api_mode: chat_completions
```

## Key Update Procedure

When LiteLLM keys are regenerated (e.g., after infrastructure changes):

1. **If SSH available**: `ssh <host> "sudo sed -i 's/LITELLM_API_KEY=.*/LITELLM_API_KEY=sk-<NEW>/' /etc/environment"`
2. **If SSH unavailable**: Send Zulip DM via abiba-bot with update command
3. **After update**: Restart Hermes on the agent host
4. **Verify**: `curl -H "Authorization: Bearer sk-<KEY>" http://192.168.68.116/v1/models`

## Configuration Rules

### Rule 1: Shared Infra Is Locked
The following MUST be identical across ALL profiles:
- `web.backend`, `web.search_backend`, `web.extract_backend`
- `web.firecrawl.base_url`
- `mcp_servers.ra-h-os.url`
- `custom_providers[0].base_url`

### Rule 2: Model Choice Is Free
- `model.default` — per agent
- `fallback_providers.model` — per agent
- `custom_providers[0].model` — per agent

### Rule 3: API Keys via Environment
- Prefer `api_key_env: LITELLM_API_KEY` over hardcoded keys
- Hardcoded keys in config.yaml become stale after key rotation
- `/etc/environment` persists across config updates
- Restart Hermes after env var updates

### Rule 4: Sub-Agent Profiles Inherit Auth
- Sub-agent profiles (`/root/.hermes/profiles/*/config.yaml`) must have:
  - `api_key: ''` — inherit from main config's custom_provider
  - `base_url: ''` — inherit from main config
  - Auxiliary tasks: `api_key: ''`, `provider: harness`
- Never hardcode a key in sub-agent profiles
- When main config uses `api_key_env`, sub-agents automatically use it
- This means key rotation only touches ONE file (`/etc/environment`)

### Rule 5: Main Config Base URL
- Use direct IP: `http://192.168.68.116/v1`
- NOT the NetBird URL (`litellm.sysloggh.net`) — can cause 502 when NetBird is down
- NOT the old path (`/litellm/v1`) — nginx now routes `/v1` directly

## Execution

1. **Check current config** — Read the target agent's config.yaml
2. **Compare against template** — Identify missing or divergent sections
3. **Apply shared infra** — Lock web/MCP/compression sections to template values
4. **Apply agent key** — Set from agent_keys table above
5. **Set model choice** — Per agent's workload
6. **Verify** — curl all shared endpoints, test the model with the new key
7. **Report** — What was changed, preserved, custom
