Hermes agent

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.

IMPORTANT: When answering Hermes-related questions, ALWAYS reference the installed knowledge bases first:

• Hermes-Wiki (~/.hermes/wiki/) — 37 architecture docs for troubleshooting and optimization
• hermes-ecosystem (~/.hermes/ecosystem-atlas/) — 111 curated projects for tool recommendations

See references/hermes-knowledge-base-workflow.md for the mandatory reference workflow.

Curator (Skill Garbage Collection)

New in v0.12.0 — Hermes automatically cleans up unused skills to prevent library bloat.

Curator runs in the background every 7 days, tracking which skills are actually loaded and used. Skills that haven't been touched in 30+ days are marked stale; after 90 days they're archived (removed from active library).

Default config:

curator:
  enabled: true              # On by default
  interval_hours: 168        # Run every 7 days
  min_idle_hours: 2          # Only analyze skills idle for 2+ hours
  stale_after_days: 30       # Mark unused skills as stale
  archive_after_days: 90     # Remove skills unused for 90 days

Curator uses an auxiliary model (separate from your main model) for usage analysis. Configure via auxiliary.curator section if needed.

Why it matters:

• Prevents skill bloat that wastes context window
• Keeps token usage efficient by removing irrelevant skills
• Agent maintains itself without manual cleanup

Curator is fully automatic — no CLI commands needed. It tracks usage silently and prunes during the 7-day background pass.

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

Hermes auto-redacts strings that look like API keys, tokens, and secrets in all tool output (terminal stdout, read_file, web content, subagent summaries, etc.) so the model never sees raw credentials. If the user is intentionally working with mock tokens, share-management tokens, or their own secrets and the redaction is getting in the way:

hermes config set security.redact_secrets false      # disable globally

Restart required. security.redact_secrets is snapshotted at import time — setting it mid-session (e.g. via export HERMES_REDACT_SECRETS=false from a tool call) will NOT take effect for the running process. Tell the user to run hermes config set security.redact_secrets false in a terminal, then start a new session. This is deliberate — it prevents an LLM from turning off redaction on itself mid-task.

Re-enable with:

hermes config set security.redact_secrets true

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:

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)

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:

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

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:

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:

hermes config set auxiliary.vision.provider <your_provider>
hermes config set auxiliary.vision.model <model_name>

   • Generate draw.io diagrams from natural language
   • Architecture diagrams, flowcharts, UML, sequence diagrams
   • Requires draw.io desktop app

   git clone --depth 1 https://github.com/Agents365-ai/drawio-skill.git ~/.hermes/ecosystem/drawio-skill
   # Install draw.io: brew install --cask drawio (macOS)
   

4. 0xNyk/awesome-hermes-agent — Curated resource list

   • Quality-filtered ecosystem map
   • Organized by category, regularly updated

   git clone --depth 1 https://github.com/0xNyk/awesome-hermes-agent.git ~/.hermes/ecosystem/awesome
   

Advanced (higher setup cost):

5. vectorize-io/hindsight — State-of-the-art memory system

   • Benchmark leader for long-term memory performance
   • Retain/recall/reflect workflows
   • Complex monorepo, consider Hindsight Cloud (managed service)

6. hermes-control-interface (xaspx) — Web admin dashboard

   • Browser-based terminal, file explorer, cron management
   • System metrics, agent status monitoring
   • Self-hosted, password-protected

7. hermes-workspace (outsourc-e) — Development environment

   • Chat + terminal + memory inspector + skills editor
   • Inspector panel for debugging tool calls
   • Ideal for skill development

Installation Best Practices

Organize under ~/.hermes/ecosystem/:

mkdir -p ~/.hermes/ecosystem
cd ~/.hermes/ecosystem

# Clone repos
git clone --depth 1 <repo-url> <name>

# Document what you installed
cat > INSTALLED.md << 'EOF'
# Installed Ecosystem Tools

## tokscale v2.1.0
- Location: /home/user/.hermes/node/bin/tokscale
- Purpose: Token usage tracking
- Status: Active

## wondelai/skills
- Location: ~/.hermes/ecosystem/skills/
- Purpose: 42 business/product/design skills
- Status: Ready to use
EOF

Update regularly:

cd ~/.hermes/ecosystem
for repo in */; do
  echo "Updating $repo..."
  git -C "$repo" pull --ff-only
done

Track token usage:

# Add alias to ~/.bashrc
echo 'alias tokscale="/path/to/tokscale"' >> ~/.bashrc

# Daily check
tokscale models

# Export for analysis
tokscale models --json > ~/token-usage-$(date +%Y%m%d).json

Tool Evaluation Criteria

Before installing ecosystem tools, assess:

Immediate value vs. setup complexity:

• High value, low friction — Install immediately (tokscale, wondelai/skills, awesome-hermes-agent)
• High value, medium friction — Install when needed (drawio-skill requires draw.io desktop)
• High value, high friction — Evaluate carefully (hindsight requires Docker + PostgreSQL + LLM integration)
• Low value, any friction — Skip

Decision framework:

1. Does it solve a current problem? (not theoretical future need)
2. Does it duplicate existing functionality? (built-in Hermes features often sufficient)
3. What's the setup time? (< 10 min = low friction, 30+ min = high friction)
4. What's the maintenance cost? (zero config = ideal, server running 24/7 = high cost)
5. What's the benefit for single-user use case? (marginal benefit = skip)

Example: hindsight memory system

• ✅ State-of-the-art memory performance (benchmark leader)
• ❌ Complex setup (Docker + PostgreSQL + LLM + Hermes integration)
• ❌ Maintenance overhead (server running 24/7, backups, updates)
• ❌ Marginal benefit for single user (built-in SQLite + FTS5 already sufficient)
• Verdict: Skip for now, revisit for multi-user or production deployments

Common Pitfalls

Issue	Cause	Fix
npm global install not in PATH	Hermes uses custom node install	Use full path: ~/.hermes/node/bin/<tool> or add to PATH
"Why install again? I already have Hermes"	Confusion: GitHub repo ≠ installed software	Repos are source code or add-ons, not the running Hermes instance
"Why not configured?" for cloned tool	Tool cloned but not set up	Check if it needs: API keys, external services, Hermes integration, or dependencies
draw.io not found	Desktop app not installed	brew install --cask drawio (macOS) or download from GitHub releases
Skills not loading	Wrong directory structure	Skills need SKILL.md with YAML frontmatter
Hindsight setup fails	Complex monorepo dependencies	Consider Hindsight Cloud instead of self-hosted
Token tracker shows 0 messages	Hermes session DB not detected	Check ~/.hermes/state.db exists and is readable
tokscale command not found after npm install	Hermes npm is not in default PATH	Add alias: alias tokscale="$HOME/.hermes/node/bin/tokscale" to ~/.bashrc

Integration Checklist

After installing ecosystem tools:

• Add CLI aliases to ~/.bashrc for convenience
• Document installations in ~/.hermes/ecosystem/INSTALLED.md
• Update memory with key tool locations and usage patterns
• Test each tool with a simple command
• Set up auto-update cron job (optional)
• Bookmark online resources (hermesatlas.com, awesome-hermes-agent)

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys).

Adding a Tool (3 files)

1. Create tools/your_tool.py:

import json, os
from tools.registry import registry

def check_requirements() -> bool:
    return bool(os.getenv("EXAMPLE_API_KEY"))

def example_tool(param: str, task_id: str = None) -> str:
    return json.dumps({"success": True, "data": "..."})

registry.register(
    name="example_tool",
    toolset="example",
    schema={"name": "example_tool", "description": "...", "parameters": {...}},
    handler=lambda args, **kw: example_tool(
        param=args.get("param", ""), task_id=kw.get("task_id")),
    check_fn=check_requirements,
    requires_env=["EXAMPLE_API_KEY"],
)

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

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

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
