propagate handler exit codes
Live testing the full wizard against the real v0.39.0 binary
(downloaded + extracted via our own install_iron_proxy()) surfaced
three real bugs that the unit tests couldn't catch:
1. `proxy.http_listens` (plural) — NOT a field in v0.39's config struct.
Our code emitted both `http_listen` (string) and `http_listens`
(list) believing v0.39 accepts both forms. The binary actually
rejects with "field http_listens not found in type config.Proxy"
at YAML unmarshal time, so the daemon fails to start. Confirmed
via strings(1) audit of the v0.39 binary — only `http_listen` is
tagged.
2. `log.audit_path` — NOT a field in v0.39's config.Log struct. Same
class of error: "field audit_path not found in type config.Log".
Per-request audit-log records are not separable from server-level
logs at this binary version.
3. `metrics.listen` defaults to ":9090" — which is the SAME port as
our default `tunnel_port: 9090`. Result: every operator who runs
`hermes egress setup` followed by `hermes egress start` gets
"bind: address already in use" because the proxy listener and the
metrics listener fight for port 9090. We now explicitly pin
`metrics.listen: 127.0.0.1:0` to give it an ephemeral loopback
port that can never collide with tunnel_port regardless of what
operator sets.
Plus a fourth bug — pre-existing but surfaced by the egress live
test — that affects every Hermes subcommand:
4. `hermes_cli/main.py` calls `args.func(args)` at the bottom of
main() but discards the return value. Every subcommand handler
that returns a non-zero exit code (cmd_start refusing because
`fail_on_uncovered_providers=true`, cmd_setup refusing because
--from-bitwarden but BWS unreachable, etc.) was silently exiting 0.
Fix: capture the handler's return value and `sys.exit(rc)` when
it's a non-zero int. Other subcommands' contracts unchanged
because they either return 0/None or don't return at all.
Validation:
- 188/188 in test_iron_proxy.py + test_iron_proxy_cli.py +
test_config.py pass post-fix.
- 5333/5337 in tests/hermes_cli/ pass; the 4 unrelated failures
(test_managed_installs.py + test_update_hangup_protection.py)
are pre-existing on main, not touched by this PR.
- Manual wizard run end-to-end with the v0.39.0 binary in an
isolated HERMES_HOME:
* `egress install` — downloads + SHA-256 verifies + extracts
* `egress setup` — generates CA, mints tokens, writes
proxy.yaml that the binary now accepts (no http_listens,
no audit_path, metrics pinned to 127.0.0.1:0)
* `egress start` — daemon binds 127.0.0.1:9090, listens=yes
* `egress status` — shows pid + listening + mappings
* `egress stop` — clean shutdown, pidfile + nonce removed
* Idempotent re-start returns the running pid without spawning
* curl through the proxy with the openrouter token gets
forwarded; an attacker host gets HTTP 403 (allowlist works);
169.254.169.254 gets HTTP 403 (deny CIDR works)
* Refuse-start paths exit 1 with actionable messages:
- `fail_on_uncovered_providers=true` + ANTHROPIC_API_KEY set
- `credential_source=bitwarden` + BWS_ACCESS_TOKEN unset
* `--rotate-tokens` confirmation gate fires via pty:
typing 'cancel' aborts; typing 'rotate' proceeds and
creates a mappings.json.rotated-<timestamp> backup
Test updates:
- `test_default_bind_is_loopback_not_zero_zero` — asserts the
singular `http_listen` is loopback AND asserts `http_listens`
(plural) is NOT in the rendered yaml.
- `test_default_bind_uses_loopback_on_linux` — replaces
`test_default_bind_includes_docker_bridge_on_linux`. v0.39
only supports one bind per daemon process, so the docker bridge
augmentation is dropped from the rendered config; sandboxes
reach the daemon via host.docker.internal -> host-gateway
mapping, so loopback-only is functional.
- `test_metrics_listener_pinned_to_loopback_ephemeral` — new
regression test asserting `metrics.listen == "127.0.0.1:0"`.
- `test_audit_log_kwarg_does_not_inject_audit_path_v039` —
replaces `test_audit_log_path_lands_in_yaml`. audit_log kwarg
is still accepted for forward compatibility but does NOT emit
log.audit_path until upstream supports it.

Hermes Agent ☤
The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
Use any model you want — Nous Portal, OpenRouter (200+ models), NovitaAI (AI-native cloud for Model API, Agent Sandbox, and GPU Cloud), NVIDIA NIM (Nemotron), Xiaomi MiMo, z.ai/GLM, Kimi/Moonshot, MiniMax, Hugging Face, OpenAI, or your own endpoint. Switch with hermes model — no code changes, no lock-in.
| A real terminal interface | Full TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output. |
| Lives where you do | Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity. |
| A closed learning loop | Agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard. |
| Scheduled automations | Built-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended. |
| Delegates and parallelizes | Spawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns. |
| Runs anywhere, not just your laptop | Seven terminal backends — local, Docker, SSH, Singularity, Modal, Daytona, and Vercel Sandbox. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster. |
| Research-ready | Batch trajectory generation, trajectory compression for training the next generation of tool-calling models. |
Quick Install
Linux, macOS, WSL2, Termux
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
Windows (native, PowerShell) — Early Beta
Heads up: Native Windows support is early beta. It installs and runs, but hasn't been road-tested as broadly as our Linux/macOS/WSL2 paths. Please file issues when you hit rough edges. For the most battle-tested Windows setup today, run the Linux/macOS one-liner above inside WSL2.
Run this in PowerShell:
iex (irm https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.ps1)
The installer handles everything: uv, Python 3.11, Node.js, ripgrep, ffmpeg, and a portable Git Bash (MinGit, unpacked to %LOCALAPPDATA%\hermes\git — no admin required, completely isolated from any system Git install). Hermes uses this bundled Git Bash to run shell commands.
If you already have Git installed, the installer detects it and uses that instead. Otherwise a ~45MB MinGit download is all you need — it won't touch or interfere with any system Git.
Android / Termux: The tested manual path is documented in the Termux guide. On Termux, Hermes installs a curated
.[termux]extra because the full.[all]extra currently pulls Android-incompatible voice dependencies.Windows: Native Windows is supported as an early beta — the PowerShell one-liner above installs everything, but expect rough edges and please file issues when you hit them. If you'd rather use WSL2 (our most battle-tested Windows path), the Linux command works there too. Native Windows install lives under
%LOCALAPPDATA%\hermes; WSL2 installs under~/.hermesas on Linux. The only Hermes feature that currently needs WSL2 specifically is the browser-based dashboard chat pane (it uses a POSIX PTY — classic CLI and gateway both run natively).
After installation:
source ~/.bashrc # reload shell (or: source ~/.zshrc)
hermes # start chatting!
Getting Started
hermes # Interactive CLI — start a conversation
hermes model # Choose your LLM provider and model
hermes tools # Configure which tools are enabled
hermes config set # Set individual config values
hermes gateway # Start the messaging gateway (Telegram, Discord, etc.)
hermes setup # Run the full setup wizard (configures everything at once)
hermes claw migrate # Migrate from OpenClaw (if coming from OpenClaw)
hermes update # Update to the latest version
hermes doctor # Diagnose any issues
Skip the API-key collection — Nous Portal
Hermes works with whatever provider you want — that's not changing. But if you'd rather not collect five separate API keys for the model, web search, image generation, TTS, and a cloud browser, Nous Portal covers all of them under one subscription:
- 300+ models — pick any of them with
/model <name> - Tool Gateway — web search (Firecrawl), image generation (FAL), text-to-speech (OpenAI), cloud browser (Browser Use), all routed through your sub. No extra accounts.
One command from a fresh install:
hermes setup --portal
That logs you in via OAuth, sets Nous as your provider, and turns on the Tool Gateway. Check what's wired up any time with hermes portal status. Full details on the Tool Gateway docs page.
You can still bring your own keys per-tool whenever you want — the gateway is per-backend, not all-or-nothing.
CLI vs Messaging Quick Reference
Hermes has two entry points: start the terminal UI with hermes, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.
| Action | CLI | Messaging platforms |
|---|---|---|
| Start chatting | hermes |
Run hermes gateway setup + hermes gateway start, then send the bot a message |
| Start fresh conversation | /new or /reset |
/new or /reset |
| Change model | /model [provider:model] |
/model [provider:model] |
| Set a personality | /personality [name] |
/personality [name] |
| Retry or undo the last turn | /retry, /undo |
/retry, /undo |
| Compress context / check usage | /compress, /usage, /insights [--days N] |
/compress, /usage, /insights [days] |
| Browse skills | /skills or /<skill-name> |
/<skill-name> |
| Interrupt current work | Ctrl+C or send a new message |
/stop or send a new message |
| Platform-specific status | /platforms |
/status, /sethome |
For the full command lists, see the CLI guide and the Messaging Gateway guide.

Migrating from OpenClaw
If you're coming from OpenClaw, Hermes can automatically import your settings, memories, skills, and API keys.
During first-time setup: The setup wizard (hermes setup) automatically detects ~/.openclaw and offers to migrate before configuration begins.
Anytime after install:
hermes claw migrate # Interactive migration (full preset)
hermes claw migrate --dry-run # Preview what would be migrated
hermes claw migrate --preset user-data # Migrate without secrets
hermes claw migrate --overwrite # Overwrite existing conflicts
What gets imported:
- SOUL.md — persona file
- Memories — MEMORY.md and USER.md entries
- Skills — user-created skills →
~/.hermes/skills/openclaw-imports/ - Command allowlist — approval patterns
- Messaging settings — platform configs, allowed users, working directory
- API keys — allowlisted secrets (Telegram, OpenRouter, OpenAI, Anthropic, ElevenLabs)
- TTS assets — workspace audio files
- Workspace instructions — AGENTS.md (with
--workspace-target)
See hermes claw migrate --help for all options, or use the openclaw-migration skill for an interactive agent-guided migration with dry-run previews.
