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:
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.

Full enumeration lives in toolsets.py as the TOOLSETS dict; _HERMES_CORE_TOOLS is the default bundle most platforms inherit from.
Tool changes take effect on /reset (new session). They do NOT apply mid-conversation to preserve prompt caching.
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 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:
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:
hermes config set security.redact_secrets false
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)
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-riskoff — 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=1Note: YOLO / approvals.mode: off does NOT turn off secret redaction. They are independent.
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.
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.

Hermes runs natively on Windows (PowerShell, cmd, Windows Terminal, git-bash mintty, VS Code integrated terminal). Most of it just works, but a handful of differences between Win32 and POSIX have bitten us — document new ones here as you hit them so the next person (or the next session) doesn't rediscover them from scratch.
Alt+Enter doesn't insert a newline. Windows Terminal intercepts Alt+Enter
at the terminal layer to toggle fullscreen — the keystroke never reaches
prompt_toolkit. Use Ctrl+Enter instead. Windows Terminal delivers
Ctrl+Enter as LF (c-j), distinct from plain Enter (c-m / CR), and the
CLI binds c-j to newline insertion on win32 only (see
_bind_prompt_submit_keys + the Windows-only c-j binding in cli.py).
Side effect: the raw Ctrl+J keystroke also inserts a newline on Windows —
unavoidable, because Windows Terminal collapses Ctrl+Enter and Ctrl+J to
the same keycode at the Win32 console API layer. No conflicting binding
existed for Ctrl+J on Windows, so this is a harmless side effect.
mintty / git-bash behaves the same (fullscreen on Alt+Enter) unless you disable Alt+Fn shortcuts in Options → Keys. Easier to just use Ctrl+Enter.
Diagnosing keybindings. Run python scripts/keystroke_diagnostic.py
(repo root) to see exactly how prompt_toolkit identifies each keystroke
in the current terminal. Answers questions like "does Shift+Enter come
through as a distinct key?" (almost never — most terminals collapse it
to plain Enter) or "what byte sequence is my terminal sending for
Ctrl+Enter?" This is how the Ctrl+Enter = c-j fact was established.
HTTP 400 "No models provided" on first run. config.yaml was saved
with a UTF-8 BOM (common when Windows apps write it). Re-save as UTF-8
without BOM. hermes config edit writes without BOM; manual edits in
Notepad are the usual culprit.
execute_code / SandboxWinError 10106 ("The requested service provider could not be loaded
or initialized") from the sandbox child process — it can't create an
AF_INET socket, so the loopback-TCP RPC fallback fails before
connect(). Root cause is usually not a broken Winsock LSP; it's
Hermes's own env scrubber dropping SYSTEMROOT / WINDIR / COMSPEC
from the child env. Python's socket module needs SYSTEMROOT to locate
mswsock.dll. Fixed via the _WINDOWS_ESSENTIAL_ENV_VARS allowlist in
tools/code_execution_tool.py. If you still hit it, echo os.environ
inside an execute_code block to confirm SYSTEMROOT is set. Full

scripts/run_tests.sh doesn't work as-is on Windows — it looks for
POSIX venv layouts (.venv/bin/activate). The Hermes-installed venv at
venv/Scripts/ has no pip or pytest either (stripped for install size).
Workaround: install pytest + pytest-xdist + pyyaml into a system Python
3.11 user site, then invoke pytest directly with PYTHONPATH set:
"/c/Program Files/Python311/python" -m pip install --user pytest pytest-xdist pyyaml
export PYTHONPATH="$(pwd)"
"/c/Program Files/Python311/python" -m pytest tests/foo/test_bar.py -v --tb=short -n 0
Use -n 0, not -n 4 — pyproject.toml's default addopts already
includes -n, and the wrapper's CI-parity guarantees don't apply off POSIX.
POSIX-only tests need skip guards. Common markers already in the codebase:
0o600 file modes — POSIX mode bits not enforced on NTFS by defaultsignal.SIGALRM — Unix-only (see tests/conftest.py::_enforce_test_timeout)@pytest.mark.skipif(sys.platform != "win32", ...)Use the existing skip-pattern style (sys.platform == "win32" or
sys.platform.startswith("win")) to stay consistent with the rest of the
suite.
Line endings. Git may warn LF will be replaced by CRLF the next time Git touches it. Cosmetic — the repo's .gitattributes normalizes. Don't
let editors auto-convert committed POSIX-newline files to CRLF.
Forward slashes work almost everywhere. C:/Users/... is accepted by
every Hermes tool and most Windows APIs. Prefer forward slashes in code
and logs — avoids shell-escaping backslashes in bash.

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

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys).
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.
CommandDef to COMMAND_REGISTRY in hermes_cli/commands.pycli.py → process_command()gateway/run.pyAll consumers (help text, autocomplete, Telegram menu, Slack mapping) derive from the central registry automatically.
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

HERMES_HOME to temp dirs — never touch real ~/.hermes/-o 'addopts=' to clear any baked-in pytest flagsWindows contributors: scripts/run_tests.sh currently looks for POSIX venvs (.venv/bin/activate / venv/bin/activate) and will error out on Windows where the layout is venv/Scripts/activate + python.exe. The Hermes-installed venv at venv/Scripts/ also has no pip or pytest — it's stripped for end-user install size. Workaround: install pytest + pytest-xdist + pyyaml into a system Python 3.11 user site (/c/Program Files/Python311/python -m pip install --user pytest pytest-xdist pyyaml), then run tests directly:
export PYTHONPATH="$(pwd)"
"/c/Program Files/Python311/python" -m pytest tests/tools/test_foo.py -v --tb=short -n 0
Use -n 0 (not -n 4) because pyproject.toml's default addopts already includes -n, and the wrapper's CI-parity story doesn't apply off-POSIX.
Cross-platform test guards: tests that use POSIX-only syscalls need a skip marker. Common ones already in the codebase:
@pytest.mark.skipif(sys.platform == "win32", reason="Symlinks require elevated privileges on Windows") (see tests/cron/test_cron_script.py)@pytest.mark.skipif(sys.platform.startswith("win"), reason="POSIX mode bits not enforced on Windows") (see tests/hermes_cli/test_auth_toctou_file_modes.py)signal.SIGALRM → Unix-only (see tests/conftest.py::_enforce_test_timeout)@pytest.mark.skipif(sys.platform != "win32", reason="Windows-specific regression")Monkeypatching sys.platform is not enough when the code under test also calls platform.system() / platform.release() / platform.mac_ver(). Those functions re-read the real OS independently, so a test that sets sys.platform = "linux" on a Windows runner will still see platform.system() == "Windows" and route through the Windows branch. Patch all three together:
monkeypatch.setattr(sys, "platform", "linux")
monkeypatch.setattr(platform, "system", lambda: "Linux")
monkeypatch.setattr(platform, "release", lambda: "6.8.0-generic")
See tests/agent/test_prompt_builder.py::TestEnvironmentHints for a worked example.
Factual guidance about the host OS, user home, cwd, terminal backend, and shell (bash vs. PowerShell on Windows) is emitted from agent/prompt_builder.py::build_environment_hints(). This is also where the WSL hint and per-backend probe logic live. The convention:
$HOME, cwd) + Windows-specific notes (hostname ≠ username, terminal uses bash not PowerShell)._REMOTE_TERMINAL_BACKENDS: docker, singularity, modal, daytona, ssh, vercel_sandbox, managed_modal) → suppress host info entirely and describe only the backend. A live uname/whoami/pwd probe runs inside the backend via tools.environments.get_environment(...).execute(...), cached per process in _BACKEND_PROBE_CACHE, with a static fallback if the probe times out.TERMINAL_ENV != "local", every file tool (read_file, write_file, patch, search_files) runs inside the backend container, not on the host. The system prompt must never describe the host in that case — the agent can't touch it.Full design notes, the exact emitted strings, and testing pitfalls:
references/prompt-builder-environment-hints.md.
Refactor-safety pattern (POSIX-equivalence guard): when you extract inline logic into a helper that adds Windows/platform-specific behavior, keep a _legacy_<name> oracle function in the test file that's a verbatim copy of the old code, then parametrize-diff against it. Example: tests/tools/test_code_execution_windows_env.py::TestPosixEquivalence. This locks in the invariant that POSIX behavior is bit-for-bit identical and makes any future drift fail loudly with a clear diff.
