# Hermes Agent
Hermes Agent is an open-source AI agent framework by Nous Research that runs in your terminal, messaging platforms, and IDEs. It belongs to the same category as Claude Code (Anthropic), Codex (OpenAI), and OpenClaw — autonomous coding and task-execution agents that use tool calling to interact with your system. Hermes works with any LLM provider (OpenRouter, Anthropic, OpenAI, DeepSeek, local models, and 15+ others) and runs on Linux, macOS, and WSL.
What makes Hermes different:
- **Self-improving through skills** — Hermes learns from experience by saving reusable procedures as skills. When it solves a complex problem, discovers a workflow, or gets corrected, it can persist that knowledge as a skill document that loads into future sessions. Skills accumulate over time, making the agent better at your specific tasks and environment.
- **Persistent memory across sessions** — remembers who you are, your preferences, environment details, and lessons learned. Pluggable memory backends (built-in, Honcho, Mem0, and more) let you choose how memory works.
- **Multi-platform gateway** — the same agent runs on Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, and 10+ other platforms with full tool access, not just chat.
- **Provider-agnostic** — swap models and providers mid-workflow without changing anything else. Credential pools rotate across multiple API keys automatically.
- **Profiles** — run multiple independent Hermes instances with isolated configs, sessions, skills, and memory.
- **Extensible** — plugins, MCP servers, custom tools, webhook triggers, cron scheduling, and the full Python ecosystem.
People use Hermes for software development, research, system administration, data analysis, content creation, home automation, and anything else that benefits from an AI agent with persistent context and full system access.
**This skill helps you work with Hermes Agent effectively** — setting it up, configuring features, spawning additional agent instances, troubleshooting issues, finding the right commands and settings, and understanding how the system works when you need to extend or contribute to it.

---
## Security & Privacy Toggles
Common "why is Hermes doing X to my output / tool calls / commands?" toggles — and the exact commands to change them. Most of these need a fresh session (`/reset` in chat, or start a new `hermes` invocation) because they're read once at startup.
### Secret redaction in tool output
Secret redaction is **off by default** — tool output (terminal stdout, `read_file`, web content, subagent summaries, etc.) passes through unmodified. If the user wants Hermes to auto-mask strings that look like API keys, tokens, and secrets before they enter the conversation context and logs:
```bash
hermes config set security.redact_secrets true # enable globally
```
**Restart required.** `security.redact_secrets` is snapshotted at import time — toggling it mid-session (e.g. via `export HERMES_REDACT_SECRETS=true` from a tool call) will NOT take effect for the running process. Tell the user to run `hermes config set security.redact_secrets true` in a terminal, then start a new session. This is deliberate — it prevents an LLM from flipping the toggle on itself mid-task.
Disable again with:
```bash
hermes config set security.redact_secrets false
```
### PII redaction in gateway messages
Separate from secret redaction. When enabled, the gateway hashes user IDs and strips phone numbers from the session context before it reaches the model:
```bash
hermes config set privacy.redact_pii true # enable
hermes config set privacy.redact_pii false # disable (default)
```
### Command approval prompts
By default (`approvals.mode: manual`), Hermes prompts the user before running shell commands flagged as destructive (`rm -rf`, `git reset --hard`, etc.). The modes are:
- `manual` — always prompt (default)
- `smart` — use an auxiliary LLM to auto-approve low-risk commands, prompt on high-risk
- `off` — skip all approval prompts (equivalent to `--yolo`)
```bash
hermes config set approvals.mode smart # recommended middle ground
hermes config set approvals.mode off # bypass everything (not recommended)
```
Per-invocation bypass without changing config:
- `hermes --yolo …`
- `export HERMES_YOLO_MODE=1`
Note: YOLO / `approvals.mode: off` does NOT turn off secret redaction. They are independent.
### Shell hooks allowlist
Some shell-hook integrations require explicit allowlisting before they fire. Managed via `~/.hermes/shell-hooks-allowlist.json` — prompted interactively the first time a hook wants to run.
### Disabling the web/browser/image-gen tools
To keep the model away from network or media tools entirely, open `hermes tools` and toggle per-platform. Takes effect on next session (`/reset`). See the Tools & Skills section above.
---
## Voice & Transcription
### STT (Voice → Text)
Voice messages from messaging platforms are auto-transcribed.
Provider priority (auto-detected):
1. **Local faster-whisper** — free, no API key: `pip install faster-whisper`
2. **Groq Whisper** — free tier: set `GROQ_API_KEY`
3. **OpenAI Whisper** — paid: set `VOICE_TOOLS_OPENAI_KEY`
4. **Mistral Voxtral** — set `MISTRAL_API_KEY`
Config:
```yaml
stt:
enabled: true
provider: local # local, groq, openai, mistral
local:
model: base # tiny, base, small, medium, large-v3
```
### TTS (Text → Voice)
| Provider | Env var | Free? |
|----------|---------|-------|
| Edge TTS | None | Yes (default) |
| ElevenLabs | `ELEVENLABS_API_KEY` | Free tier |
| OpenAI | `VOICE_TOOLS_OPENAI_KEY` | Paid |
| MiniMax | `MINIMAX_API_KEY` | Paid |
| Mistral (Voxtral) | `MISTRAL_API_KEY` | Paid |
| NeuTTS (local) | None (`pip install neutts[all]` + `espeak-ng`) | Free |
Voice commands: `/voice on` (voice-to-voice), `/voice tts` (always voice), `/voice off`.

## Spawning Additional Hermes Instances
Run additional Hermes processes as fully independent subprocesses — separate sessions, tools, and environments.
### When to Use This vs delegate_task
| | `delegate_task` | Spawning `hermes` process |
|-|-----------------|--------------------------|
| Isolation | Separate conversation, shared process | Fully independent process |
| Duration | Minutes (bounded by parent loop) | Hours/days |
| Tool access | Subset of parent's tools | Full tool access |
| Interactive | No | Yes (PTY mode) |
| Use case | Quick parallel subtasks | Long autonomous missions |
### One-Shot Mode
```
terminal(command="hermes chat -q 'Research GRPO papers and write summary to ~/research/grpo.md'", timeout=300)
# Background for long tasks:
terminal(command="hermes chat -q 'Set up CI/CD for ~/myapp'", background=true)
```
### Interactive PTY Mode (via tmux)
Hermes uses prompt_toolkit, which requires a real terminal. Use tmux for interactive spawning:
```
# Start
terminal(command="tmux new-session -d -s agent1 -x 120 -y 40 'hermes'", timeout=10)
# Wait for startup, then send a message
terminal(command="sleep 8 && tmux send-keys -t agent1 'Build a FastAPI auth service' Enter", timeout=15)
# Read output
terminal(command="sleep 20 && tmux capture-pane -t agent1 -p", timeout=5)
# Send follow-up
terminal(command="tmux send-keys -t agent1 'Add rate limiting middleware' Enter", timeout=5)
# Exit
terminal(command="tmux send-keys -t agent1 '/exit' Enter && sleep 2 && tmux kill-session -t agent1", timeout=10)
```
### Multi-Agent Coordination
```
# Agent A: backend
terminal(command="tmux new-session -d -s backend -x 120 -y 40 'hermes -w'", timeout=10)
terminal(command="sleep 8 && tmux send-keys -t backend 'Build REST API for user management' Enter", timeout=15)
# Agent B: frontend
terminal(command="tmux new-session -d -s frontend -x 120 -y 40 'hermes -w'", timeout=10)
terminal(command="sleep 8 && tmux send-keys -t frontend 'Build React dashboard for user management' Enter", timeout=15)
# Check progress, relay context between them
terminal(command="tmux capture-pane -t backend -p | tail -30", timeout=5)
terminal(command="tmux send-keys -t frontend 'Here is the API schema from the backend agent: ...' Enter", timeout=5)
```
### Session Resume
```
# Resume most recent session
terminal(command="tmux new-session -d -s resumed 'hermes --continue'", timeout=10)
# Resume specific session
terminal(command="tmux new-session -d -s resumed 'hermes --resume 20260225_143052_a1b2c3'", timeout=10)
```
### Tips
- **Prefer `delegate_task` for quick subtasks** — less overhead than spawning a full process
- **Use `-w` (worktree mode)** when spawning agents that edit code — prevents git conflicts
- **Set timeouts** for one-shot mode — complex tasks can take 5-10 minutes
- **Use `hermes chat -q` for fire-and-forget** — no PTY needed
- **Use tmux for interactive sessions** — raw PTY mode has `\r` vs `\n` issues with prompt_toolkit
- **For scheduled tasks**, use the `cronjob` tool instead of spawning — handles delivery and retry
---
## Troubleshooting
### Voice not working
1. Check `stt.enabled: true` in config.yaml
2. Verify provider: `pip install faster-whisper` or set API key
3. In gateway: `/restart`. In CLI: exit and relaunch.
### Tool not available
1. `hermes tools` — check if toolset is enabled for your platform
2. Some tools need env vars (check `.env`)
3. `/reset` after enabling tools
### Performance / latency issues (sluggish responses)
When Hermes feels unresponsive, isolate the bottleneck before changing anything:
1. Identify the current model/provider: `hermes config | grep -A3 Model:`
2. Benchmark raw API latency with a minimal chat call:
```bash
API_KEY=$(grep '^OLLAMA_API_KEY=' ~/.hermes/.env | head -1 | cut -d= -f2)
time curl -s --max-time 15 -X POST https://ollama.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $API_KEY" \
-d '{"model":"<current-model>","messages":[{"role":"user","content":"hi"}],"max_tokens":5}' \
-o /dev/null -w "HTTP: %{http_code} | TTFB: %{time_starttransfer}s | Total: %{time_total}s\n"
```
3. If TTFB > 2s, test alternative models from the same provider:
```bash
curl -s https://ollama.com/v1/models | python3 -c "
import sys,json
models=json.load(sys.stdin)['data']
print(f'Total models: {len(models)}')
[print(m['id']) for m in models if 'deepseek' in m['id'].lower()]"
```
4. Benchmark each candidate with the same curl command above and pick the fastest variant.
5. Switch: `hermes config set model.default <faster-model>`
6. Restart: `hermes gateway restart`
Common pattern: heavy reasoning models (e.g. deepseek-v4-pro) generate internal reasoning tokens before visible output, causing 3-5s+ TTFB even with reasoning display off. Their smaller/flash variants are typically 3-5x faster with minimal capability loss for agent tool-use workflows. Multi-turn agent interactions compound this — a 5-tool-call task at 4s/turn = 20s vs 5s with a flash variant.
### Model/provider issues
1. `hermes doctor` — check config and dependencies
2. `hermes login` — re-authenticate OAuth providers
3. Check `.env` has the right API key
4. **Copilot 403**: `gh auth login` tokens do NOT work for Copilot API. You must use the Copilot-specific OAuth device code flow via `hermes model` → GitHub Copilot.
### Changes not taking effect
- **Tools/skills:** `/reset` starts a new session with updated toolset
- **Config changes:** In gateway: `/restart`. In CLI: exit and relaunch.
- **Code changes:** Restart the CLI or gateway process
### Skills not showing
1. `hermes skills list` — verify installed
2. `hermes skills config` — check platform enablement
3. Load explicitly: `/skill name` or `hermes -s name`
### Gateway issues
Check logs first:
```bash
grep -i "failed to send\|error" ~/.hermes/logs/gateway.log | tail -20
```
Common gateway problems:
- **Gateway dies on SSH logout**: Enable linger: `sudo loginctl enable-linger $USER`
- **Gateway dies on WSL2 close**: WSL2 requires `systemd=true` in `/etc/wsl.conf` for systemd services to work. Without it, gateway falls back to `nohup` (dies when session closes).
- **Gateway crash loop**: Reset the failed state: `systemctl --user reset-failed hermes-gateway`
### Platform-specific issues
- **Discord bot silent**: Must enable **Message Content Intent** in Bot → Privileged Gateway Intents.
- **Slack bot only works in DMs**: Must subscribe to `message.channels` event. Without it, the bot ignores public channels.
- **Windows HTTP 400 "No models provided"**: Config file encoding issue (BOM). Ensure `config.yaml` is saved as UTF-8 without BOM.
### Auxiliary models not working
If `auxiliary` tasks (vision, compression, session_search) fail silently, the `auto` provider can't find a backend. Either set `OPENROUTER_API_KEY` or `GOOGLE_API_KEY`, or explicitly configure each auxiliary task's provider:
```bash
hermes config set auxiliary.vision.provider <your_provider>
hermes config set auxiliary.vision.model <model_name>
```

```
**2. Add to `toolsets.py`** → `_HERMES_CORE_TOOLS` list.
Auto-discovery: any `tools/*.py` file with a top-level `registry.register()` call is imported automatically — no manual list needed.
All handlers must return JSON strings. Use `get_hermes_home()` for paths, never hardcode `~/.hermes`.
### Adding a Slash Command
1. Add `CommandDef` to `COMMAND_REGISTRY` in `hermes_cli/commands.py`
2. Add handler in `cli.py` → `process_command()`
3. (Optional) Add gateway handler in `gateway/run.py`
All consumers (help text, autocomplete, Telegram menu, Slack mapping) derive from the central registry automatically.
### Agent Loop (High Level)
```
run_conversation():
1. Build system prompt
2. Loop while iterations < max:
a. Call LLM (OpenAI-format messages + tool schemas)
b. If tool_calls → dispatch each via handle_function_call() → append results → continue
c. If text response → return
3. Context compression triggers automatically near token limit
```
### Testing
```bash
python -m pytest tests/ -o 'addopts=' -q # Full suite
python -m pytest tests/tools/ -q # Specific area
```
- Tests auto-redirect `HERMES_HOME` to temp dirs — never touch real `~/.hermes/`
- Run full suite before pushing any change
- Use `-o 'addopts='` to clear any baked-in pytest flags
### Commit Conventions
```
type: concise subject line
Optional body.
```
Types: `fix:`, `feat:`, `refactor:`, `docs:`, `chore:`
### Key Rules
- **Never break prompt caching** — don't change context, tools, or system prompt mid-conversation
- **Message role alternation** — never two assistant or two user messages in a row
- Use `get_hermes_home()` from `hermes_constants` for all paths (profile-safe)
- Config values go in `config.yaml`, secrets go in `.env`
- New tools need a `check_fn` so they only appear when requirements are met
### Plugin Pitfalls (learned)
- **Plugins load BEFORE the CLI banner is drawn.** A `print()` in `register()` scrolls off-screen. To display something at startup after the banner: spawn a daemon thread in `register()` that polls `get_plugin_manager()._cli_ref` until `cli._app` is set, then print via `cli._console_print(...)` (prompt_toolkit-safe). Gateway mode never sets `_cli_ref` — thread just exits.
- **Reading past sessions from a plugin:** `SessionDB(read_only=True)` + `list_sessions_rich(order_by_last_active=True, compact_rows=True, exclude_sources=["cron","subagent"])` — cron sessions dominate the DB (thousands) and must be excluded. `last_active` is an epoch float. Use `get_messages(session_id)` for transcripts.
- **User plugins need enabling:** `hermes plugins enable <name>`; they stay disabled-by-default otherwise.

RAM is actually fine (9.1 GiB free of 11 GiB — not full). But two real problems are visible: load average 29.5 on a 6-core box, and kswapd0 (kernel swap daemon) burning 52% CPU = memory thrashing. Also notable: the VPS rebooted just 4 minutes ago. Let me dig into why.

Machine rebooted 4 min ago; previous boot's journal ends at 22:39 with "Under memory pressure, flushing caches" — it likely froze on memory. Right now swap is FULL (2.0/2.0 GiB) and vmstat shows heavy swap-in/out thrashing. Let me pin down who is eating the RAM and whether the last boot was an OOM crash.

Understood on the manual reboot — that clears the crash investigation. Machine is still thrashing though (system CPU at 99%, heavy disk-read storm = pages being faulted back from swap). Let me re-measure now that a few minutes have passed since boot.
Load is coming down (29.5 → 10.4) and memory pressure is easing — the worst was the post-reboot thundering herd. But RAM used is climbing (6.6G → 8.9G in 2 min) and there's a zombie finratio process. Let me check who's ballooning and whether finratio is failed.
The main consumer is finratio (the Rust pair-ratio server): ~3.3 GB RSS and a full core pegged. Let me take two quick samples to see if it's settling after reboot or genuinely stuck, and check the service/port health.
Port 5202 is down and finratio died between samples, leaving a new zombie — and memory is maxed (10.7/11.7G used, swap 100% full, pressure 41%). It looks like finratio is crash-looping: boots, balloons to ~3.3GB, gets OOM-killed, systemd restarts it, repeat. Let me confirm from the service journal.

Root cause found, definitively. finratio.service is in an OOM crash-loop: every restart it "recomputes existing pairs on boot", balloons to ~9.3 GB, gets OOM-killed, systemd restarts it (counter: 16 and climbing) — every ~20 seconds the whole box gets shoved into deep memory pressure. That's your slowness. Since 5202 never comes up anyway, I'll stop the loop now.

Done. The whole story was one problem:
1. RAM wasn't "full" — finratio.service (the FINRATIO pair-ratio server, port 5202) was OOM crash-looping: every restart it "recomputes existing pairs on boot" → balloons to 9.3 GB → OOM-killed → systemd restarts (16+ loops in ~10 min). Each loop shoved the whole VPS into swap-thrash (kswapd0 burning a core, load 29), which is why everything felt slow.
2. I stopped the service. Instant recovery: RAM 2.1/11.7 GB used, load 3.6 and falling, memory pressure ~0%, zombies cleared. Everything else (openalgo brokers, ratio, filler, hermes) is healthy.
Note: finratio is now stopped (state: failed, port 5202 down) — that's deliberate so it doesn't re-flood the box. The real bug is in its boot path: the "recompute existing pairs on boot" loads ~9 GB of data on a 12 GB machine. Next step on the checklist is fixing that startup recompute (limit rows it loads or make it lazy), then re-enable the service. Want me to dig into finratio-trade's boot code?

Session 1 loaded — it's the FINRATIO Rust chart server you were building, which is exactly the service that's now OOM crash-looping. So the fix list is clear: find why its boot recompute eats 9.3 GB, fix it, rebuild, and get port 5202 healthy. Digging in:

Raw DBs are tiny (1-2 MB) — so 9.3 GB is a runaway loop, not data volume. Prime suspect: the Renko brick size for the spread series. Let me check the stored brick size and the actual spread magnitudes:
Smoking gun found: the stored pair brick size is 0.01 rupees on a series whose values are hundreds of thousands of rupees (ULTRACEMCO 50 lots ≈ ₹6L vs ASHOKLEY 5000 lots ≈ ₹7.5L). A 1-paisa Renko brick on a monetary series = millions of bricks = 9.3 GB. Let me see the full brick-size function and the fill API path, then patch:

The API confirms the poison path too: `api_bricks` line 1578 falls back to `latest=1.0` when the pair series is empty → `pair_brick_size` persisted 0.01 into meta → every boot recompute then builds tens of millions of 1-paisa bricks on a ₹1-3 lakh series → 9.3 GB → OOM loop. The UI can also trigger this live via a tiny on-the-fly brick size. Let me check all `build_renko_bricks` call sites, then apply the three-part fix:
All three call sites covered. Now applying the fix — two patches: (1) a hard cap inside `build_renko_bricks` that refuses absurd builds before allocating, (2) `pair_brick_size` rejecting stale/bogus stored sizes that are far below the series' real scale, then wiping the poisoned 0.01 from the DB:

Excellent forensics material — the journal shows the guard DID its job (refused 27M-brick builds), SUM mode built fine (1911 bricks), but SPREAD still got 0.01. Why? My own scale-floor has the same negative-input bug: `nice_round(-301150 × 0.001)` → 0.01, so the poisoned stored 0.01 passed its own floor check.

1. Session 1's FINRATIO server was the exact culprit slowing the VPS: it was OOM crash-looping (16+ restarts, 9.3 GB peak each time).
2. Root cause: ULTRACEMCO-ASHOKLEY SPREAD is NEGATIVE (₹5.86L − ₹8.87L ≈ −₹3.0L). The brick-size function `nice_round()` returns 0.01 for any negative input → 1-paisa Renko bricks on a ₹3-lakh series → ~27 million bricks → RAM explosion → OOM kill → systemd restart → repeat.
3. Fixes applied in finratio-trade:
- brick size now computed from |close| (negative spreads are legal and fine)
- hard guard in the Renko builder: refuses any build above 2M bricks
- stored brick_size sanity floor (won't re-accept a poisoned tiny value)
- UI: brick "2" now means AUTO for pairs (server's pre-computed rupee-scale bricks); custom too-small sizes refused politely
- systemd unit capped at MemoryMax=3G as a last-resort net
4. Verified live: SPREAD builds at ₹2,000/brick (values −₹1.5L to −₹4.4L render correctly), SUM at ₹10,000/brick, boot recompute 0.2s, process RSS 15 MB (was 9.3 GB), API + https://tcharts.openalgo.theworkpc.com/finratio/ both 200.
5. VPS now: load 0.49, RAM 2.4/11.7 GB used, memory pressure 0% — everything fast again.
The bug also explains why it only died after your manual reboot — that reboot triggered the boot-time "recompute existing pairs" which hit the poisoned brick size. It's cured at the source now.

i m not able to see candles 's movement as y axis is fixed - can i do zoom on y axis
The chart auto-fits the Y axis to the visible bars — no manual zoom exists. Let me check the existing mouse handling (X zoom) so the Y zoom integrates cleanly:
Y zoom it is — wheel-to-zoom on the main chart, anchored at the cursor, double-click to reset to auto-fit. Two patches — first make the Y range respect a manual view:

{"output": "patched both panels", "exit_code": 0, "error": null, "approval": "Command was flagged (script execution via heredoc) and auto-approved by smart approval."}
All behaviors verified: zoom-in works, zoom-out now caps at exactly 3× auto-fit (1,740,000 = 580,000×3), double-click resets, no JS errors. Final visual check of the zoomed view with the adaptive label gutter:
[Tool: vision_analyze]
Image loaded into your context — you can see it natively now. Use your built-in vision to answer the user.
Question: Is the main chart now zoomed vertically (Y axis shows a narrow price range, candles magnified)? Are the Y axis labels on the left fully visible without clipping? Do the RSI and MACD panels below align with the main chart's left edge?

Y-axis zoom is live and verified. How to use it on the finratio chart:
1. Mouse wheel over the chart: scroll up = zoom IN, scroll down = zoom OUT. The zoom anchors at your cursor's price level (the price under the mouse stays under the mouse), so you can dive into exactly the region you want to inspect.
2. Double-click: resets to auto-fit.
3. Guards: zoom-out caps at 3× the normal auto-fit range (can't push the chart into a flat line), zoom-in can go deep but not below a few pixels of span, and the zoom resets automatically when you switch pairs (different series = different scale).
4. Bonus fixes while testing: Y-axis labels no longer clip when zoomed (the left gutter now adapts to the widest label — you can see full values like 340764.91), and the RSI/MACD panels stay aligned with the main chart's left edge.
Verified in a real browser: auto-fit −60k→520k, zoom-in to 150k→340k with candles magnified, zoom-out capped exactly at 3× (1.74M), double-click restores −60k→520k, zero JS errors.
Note: it's per-session (not saved with the pair config) — say the word if you want the zoom level saved into saved pairs too.
