* fix(nix): fold makeWrapper line continuations into optionalStrings
When rev == null (any dirty-tree build), the empty optionalString
expansion left the previous line's trailing backslash dangling onto a
blank line, ending the makeWrapper command early and running
`--suffix PYTHONPATH ...` as its own shell command (`--suffix: command
not found`, exit 127). Clean trees passed CI; dirty trees with
extraPythonPackages failed — exactly the path the NixOS module
exercises.
The continuation now lives inside each optionalString (" \\\n --set
..."), so the makeWrapper chain stays intact whether or not the
optional flags expand.
Verified by building with rev = null + extraPythonPackages =
[ pyfiglet ]: wrapper builds, PYTHONPATH suffix lands inside the
makeWrapper call, wrapped `hermes --version` runs, and the collision
check still executes (certifi correctly rejected).
* perf(nix): filter derivation sources to shrink rebuild scope
Every derivation previously saw the whole repo, so any file change
rebuilt everything. Each derivation now gets a filtered src with only
the files it consumes:
- lib.nix: derive npm workspace topology from the root package.json
`workspaces` globs (single source of truth — a new workspace member
is picked up with zero nix edits). pythonSrc (cleanSourceWith)
excludes the JS workspace trees, docs/website, docker/.github,
tests, nix/, flake.nix/flake.lock, root docs, and skills/ +
optional-skills/. importNpmLock reads from a fileset-filtered
npmRoot (root manifests + member package.jsons only).
- mkNpmPassthru takes `dirs` — the workspace dirs the package
contains — and builds a per-package fileset src from them. web and
desktop include apps/shared (file: dep). One shared
`nix run .#update-npm-lockfile` replaces the per-package
update_*_lockfile bins that only existed inside build sandboxes.
- python.nix: release venv loads the uv2nix workspace from pythonSrc.
The editable venv keeps an unfiltered ./.. root —
mkEditablePyprojectOverlay calls lib.path.splitRoot, which rejects
a cleanSourceWith set, and the editable install reads the live
checkout anyway.
- hermes-agent.nix: skills ship exclusively via HERMES_BUNDLED_SKILLS
/ HERMES_OPTIONAL_SKILLS (same mechanism as Homebrew packaging;
setup.py's _data_file_tree returns [] for missing dirs), so
SKILL.md edits no longer rebuild the venv. optional-mcps stays in
the wheel — pyproject.toml lists its manifests as explicit
data-files. Bundled assets are symlinked instead of copied, making
the wrapper drv near-instant when only an input changed.
__pycache__ filtered from bundled skills.
- checks.nix: find -L through the new symlinks; assert
optional-skills presence + HERMES_OPTIONAL_SKILLS in the wrapper.
- run_tests.sh: fall back to $HERMES_PYTHON when no local venv
exists, guarded by an `import pytest` probe (HERMES_PYTHON from a
wrapped hermes binary points at the release venv, which has no
pytest — without the guard every test file dies with "No module
named pytest" while the runner exits 0).
Verified: nix flake check exit 0; built .#default .#tui .#web
.#desktop; SKILL.md and flake.nix edits leave the venv drvPath
unchanged; .py edits leave the tui drvPath unchanged; .tsx edits
leave the venv drvPath unchanged (and do change the tui drv);
scripts/run_tests.sh runs 299 tests green through both the venv and
HERMES_PYTHON paths, and rejects a pytest-less HERMES_PYTHON.
* refactor(nix): overlay aliases the flake's own package instead of re-instantiating
The overlay previously re-called callPackage against the consumer's
nixpkgs (final), so pkgs.hermes-agent could be a different derivation
than nix build .#default and the NixOS module's default — an untested
build matrix against arbitrary consumer nixpkgs versions, for a
package whose Python side is uv2nix-locked anyway.
Now the overlay is a pure alias for the flake's own locked package:
one callPackage site (packages.nix), everything else references it.
.override { ... } still works — callPackage's makeOverridable travels
with the derivation.
Verified: direct drvPath == overlaid drvPath; .override produces a
distinct drv.
* fix(nix): dedupe extraPlugins assertions, replace MESSAGING_CWD with terminal.cwd
- Delete the duplicated extraPlugins duplicate-name assertions block
(same assertion declared twice back to back).
- Stop setting the deprecated MESSAGING_CWD env var, which made the
module trip hermes' own startup deprecation warning. The working
directory is now injected as terminal.cwd into the generated
config.yaml; cfg.settings wins via recursiveUpdate, and container
mode maps to the in-container mount path.

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, OpenAI, your own endpoint, and many others. 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 | Six terminal backends — local, Docker, SSH, Singularity, Modal, and Daytona. 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://hermes-agent.nousresearch.com/install.sh | bash
Windows (native, PowerShell)
Heads up: Native Windows runs Hermes without WSL — CLI, gateway, TUI, and tools all work natively. If you'd rather use WSL2, the Linux/macOS one-liner above works there too. Found a bug? Please file issues.
Run this in PowerShell:
iex (irm https://hermes-agent.nousresearch.com/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 fully supported — the PowerShell one-liner above installs everything. If you'd rather use WSL2, the Linux command works there too. Native Windows install lives under
%LOCALAPPDATA%\hermes; WSL2 installs under~/.hermesas on Linux.
After installation:
source ~/.bashrc # reload shell (or: source ~/.zshrc)
hermes # start chatting!
Troubleshooting
Windows Defender or antivirus flags uv.exe as malware
If your antivirus (Bitdefender, Windows Defender, etc.) quarantines uv.exe from the Hermes bin folder (%LOCALAPPDATA%\hermes\bin\uv.exe), this is a false positive. The file is Astral's uv — the Rust Python package manager Hermes bundles to manage its Python environment. ML-based antivirus engines commonly flag unsigned Rust binaries that download and install packages.
To verify your copy is authentic:
# Install GitHub CLI if needed
winget install --id GitHub.cli
# Login to GitHub
gh auth login
# Run verification
$uv = "$env:LOCALAPPDATA\hermes\bin\uv.exe"
$ver = (& $uv --version).Split(' ')[1]
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$zip = "$env:TEMP\uv.zip"
Invoke-WebRequest "https://github.com/astral-sh/uv/releases/download/$ver/uv-x86_64-pc-windows-msvc.zip" -OutFile $zip -UseBasicParsing
gh attestation verify $zip --repo astral-sh/uv
Expand-Archive $zip "$env:TEMP\uv_x" -Force
(Get-FileHash "$env:TEMP\uv_x\uv.exe").Hash -eq (Get-FileHash $uv).Hash
If attestation says "Verification succeeded" and the last line prints True, you're good.
To whitelist Hermes:
- Windows Defender: Run PowerShell as Admin →
Add-MpPreference -ExclusionPath "$env:LOCALAPPDATA\hermes\bin" - Bitdefender: Add an exception in the Bitdefender console (Protection > Antivirus > Settings > Manage Exceptions)
- Whitelist the folder, not the file hash — Hermes updates
uvand the hash changes every version

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 info. 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.
Contributing
We welcome contributions! See the Contributing Guide for development setup, code style, and PR process.
Quick start for contributors — use the standard installer, then work from the
full git checkout it creates at $HERMES_HOME/hermes-agent (usually
~/.hermes/hermes-agent). This matches the layout used by hermes update, the
managed venv, lazy dependencies, gateway, and docs tooling.
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
uv pip install -e ".[all,dev]"
scripts/run_tests.sh
Manual clone fallback (for throwaway clones/CI where you intentionally do not want the managed install layout):
Create the venv outside the cloned source tree — a venv inside the directory the agent operates from can be wiped by a relative-path command the agent runs against its own checkout, destroying the running runtime mid-session.
curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv ~/.hermes/venvs/hermes-dev --python 3.11
source ~/.hermes/venvs/hermes-dev/bin/activate
uv pip install -e ".[all,dev]"
scripts/run_tests.sh
