Evolutionary optimize-by-metric loop — mutate a target, evaluate against fixed criteria, KEEP if the score improves (commit) or REVERT if it doesn't (git checkout), repeat, plateau-break after N stagnated runs. Adapts Karpathy's `autoresearch` pattern (and the ECC `autoresearch-agent`) with mandatory yool guardrails (§11 caps), git-isolated branch discipline, an anti-Goodhart eval order (correctness gate FIRST, score SECOND, labeled tokenizer), a local-first mutation ladder, and a `simplicio.savings-event/v1` receipt per run.

Hermes Agent is an open-source AI agent framework by Nous Research that runs in your terminal, a native desktop app, messaging platforms, and IDEs. It's in 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, Google, DeepSeek, xAI, local models, and 20+ others) and runs on Linux, macOS, Windows, 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.
Docs: https://hermes-agent.nousresearch.com/docs/
This skill is a concise operating guide, not the complete source of truth for every Hermes feature. If a Hermes feature, command, or setting is not mentioned here, do not treat that absence as evidence that it does not exist. Check the live repository and official docs before giving a negative answer.

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.
Hermes injects project-level instructions into the system prompt by reading context files from the working directory. The discovery order is first match wins — only one project context source is loaded per session.
| File (in priority order) | Discovery | Use when |
|---|---|---|
.hermes.md / HERMES.md | Walks parents up to the git root, stops at git root | You want hierarchical project rules (root + per-package overrides) |
AGENTS.md / agents.md | Cwd only — subdirectory and parent copies are ignored | You want portable agent instructions that work the same in Hermes, Claude Code, Codex, etc. |
CLAUDE.md / claude.md | Cwd only | Same as AGENTS.md, Claude-flavored |
.cursorrules / .cursor/rules/*.mdc | Cwd only | Migrating from Cursor |
SOUL.md (in $HERMES_HOME) is independent and always loaded when present — it sets the agent's identity, not project rules.
.hermes.md when you want Hermes-specific behavior that lives above the cwd (root + subtree), or when you want rules to inherit from a parent directory. The parent walk stops at the git root, so a home-level .hermes.md won't leak into every project (a git repo's root is the boundary).AGENTS.md when the same project will also be worked on by other agents (Codex, Claude Code, OpenCode). Those tools all have their own conventions for AGENTS.md, and the "cwd only" contract keeps the file portable.~/.hermes/AGENTS.md (or any other home-level location). When Hermes runs with that directory as cwd, the file loads — but only for that one directory. For cross-project context, use SOUL.md (in $HERMES_HOME, identity-only) or install a skill via simplicio-agent skills install.Each context file is capped at 20,000 characters. Files longer than that get head + tail truncated (the middle is dropped, with a [...truncated...] marker). For large project rules, prefer splitting into multiple skills over cramming one file.
All context files pass through the threat-pattern scanner before reaching the system prompt. Patterns matching prompt injection or promptware are replaced with a [BLOCKED: ...] placeholder. This means an AGENTS.md containing obvious injection attempts won't reach the model — the scanner blocks the content, not the file, so the rest of the file still loads.
simplicio-agent --ignore-rules skips auto-injection of all project context files (.hermes.md, AGENTS.md, CLAUDE.md, .cursorrules) and SOUL.md identity, plus user config, plugins, and MCP servers. Use it to isolate whether a problem is your setup or Hermes itself.
.hermes.md# My Project
Hermes: when working in this repo, follow these rules.
## Build
- Always run `make test` before declaring a change done.
- Use `uv run` for Python, not `pip install`.
## Style
- Prefer `pathlib.Path` over `os.path`.
- No `print()` in production code — use the `logger`.
That file at /home/me/projects/myrepo/.hermes.md is auto-loaded when Hermes runs in any subdirectory of /home/me/projects/myrepo, but not when it runs in /home/me/other-project.
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 on by default — tool output (terminal stdout, read_file, web content, subagent summaries, etc.) is scanned for strings that look like API keys, tokens, and secrets before it enters the conversation context and logs. Leave it enabled for normal use:
simplicio-agent config set security.redact_secrets true # keep enabled globally
Restart required. security.redact_secrets is snapshotted at import time — toggling 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 change it in config from a terminal, then start a new session. This is deliberate — it prevents an LLM from flipping the toggle on itself mid-task.
Disable only when you deliberately need raw credential-like strings for debugging or redactor development:
simplicio-agent 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:
simplicio-agent config set privacy.redact_pii true # enable
simplicio-agent config set privacy.redact_pii false # disable (default)
By default (approvals.mode: smart), Hermes asks an auxiliary LLM to assess shell commands flagged as destructive (rm -rf, git reset --hard, etc.). The modes are:
smart — auto-approve a low-risk command once, deny high-risk commands, and prompt when uncertain (default)manual — always promptoff — skip all approval prompts (equivalent to --yolo)simplicio-agent config set approvals.mode smart # recommended middle ground
simplicio-agent config set approvals.mode off # bypass everything (not recommended)
Per-invocation bypass without changing config:
simplicio-agent --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 simplicio-agent tools and toggle per-platform. Takes effect on next session (/reset). See the Tools & Skills section above.
Voice messages from messaging platforms are auto-transcribed.

Beyond the CLI and gateway, a few things worth knowing about:
hermes desktop / hermes gui) — native Electron app
for macOS/Linux/Windows: streaming chat, session list, drag-and-drop +
clipboard-paste files, Cmd+K palette, status-bar model picker,
rebindable shortcuts, native notifications, live subagent watch-windows,
VS Code Marketplace themes, and per-profile remote-gateway login (OAuth
or username/password) so a thin local GUI can drive a heavy remote agent.simplicio-agent dashboard) — full admin panel: configure
every messaging channel, the MCP catalog, webhooks/hooks, memory, and a
complete profile builder (model + skills + MCPs) from the browser, plus
an embedded simplicio-agent --tui chat. Secured behind an OAuth/token gate.hermes proxy) — exposes a
http://localhost:port OpenAI API backed by whichever OAuth provider
you're signed into (Claude Pro, ChatGPT Pro, SuperGrok). Point Codex
CLI, Aider, Cline, Continue, or any script at it — no API key.memory tool batch operations — pass an operations array of
add/replace/remove edits applied atomically against the final character
budget, so a single call can free space and add entries even when an add
alone would overflow.session_search — FTS5-backed, no aux-LLM, effectively free. One
tool, three modes inferred from which args are set: discovery (query),
scroll (session_id + around_message_id), browse (no args).grok-composer-2.5-fast coding model.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 (and mintty) grab it
for fullscreen before prompt_toolkit sees it. Use Ctrl+Enter instead (the
CLI binds it to newline on Windows; raw Ctrl+J does the same, harmlessly).
To inspect how your terminal reports a keystroke, run
python scripts/keystroke_diagnostic.py from the repo root.
HTTP 400 "No models provided" on first run — config.yaml was saved with
a UTF-8 BOM (Notepad does this). Re-save as UTF-8 without BOM;
simplicio-agent config edit writes correctly.
execute_code / SandboxWinError 10106 from the sandbox child process — it can't create an
AF_INET socket. Root cause is usually Hermes's env scrubber dropping
SYSTEMROOT/WINDIR/COMSPEC (Python's socket needs SYSTEMROOT to find
mswsock.dll), not a broken Winsock LSP. The _WINDOWS_ESSENTIAL_ENV_VARS
allowlist in tools/code_execution_tool.py covers it; if you still hit it,
echo os.environ inside an execute_code block to confirm SYSTEMROOT is set.
scripts/run_tests.sh is POSIX-only (expects .venv/bin/activate); the
Hermes-installed venv/Scripts/ has no pip/pytest (stripped for size).
Install pytest into a system Python and run directly with -n 0
(pyproject.toml's addopts already sets -n):
"/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
(POSIX-only tests need skip guards — see the cross-platform guard list in the Contributor section below.)
Line endings. Git may warn LF will be replaced by CRLF. 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.

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys) — both under $HERMES_HOME when it is set.
Two files. Auto-discovery imports any tools/*.py with a top-level
registry.register() call, but a tool is only exposed to an agent once
its name appears in a toolset.
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. Wire it into a toolset in toolsets.py — add the name to
_HERMES_CORE_TOOLS (every platform) or to a specific toolset.
All handlers must return JSON strings. Use get_hermes_home() for paths,
never hardcode ~/.hermes. For custom/local-only tools, write a plugin in
~/.hermes/plugins/ instead of editing core — see the developer docs.
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
Use the canonical runner — it enforces CI-parity (hermetic env, unset credentials, TZ=UTC, xdist workers, per-test subprocess isolation):
scripts/run_tests.sh # full suite
scripts/run_tests.sh tests/tools/ # one directory
scripts/run_tests.sh tests/tools/test_x.py # one file
scripts/run_tests.sh -v --tb=long # pass-through pytest flags
HERMES_HOME to temp dirs — never touch real ~/.hermes/..venv, then venv, then the shared worktree venv.Cross-platform test guards: tests using 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 host/backend guidance (OS, $HOME, cwd, terminal backend, shell)
is emitted by agent/prompt_builder.py::build_environment_hints(). The key
invariant for prompt authors: with a remote terminal backend
(docker, singularity, modal, daytona, ssh, managed_modal), host info is
suppressed and every file tool runs inside the backend container — the
prompt must never describe the host the agent can't touch.
