The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
Hermes Agent
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:
- 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, iMessage, Signal, Matrix, Teams, Email, and a dozen more platforms with full tool access, not just chat.
- Many surfaces — the same agent core drives the CLI, the Ink TUI, a native Electron desktop app, a web dashboard, and an ACP server for IDEs (VS Code / Zed / JetBrains).
- 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.

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.
Project Context Files
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 $HERMES_HOME) is independent and always loaded when present — it sets the agent's identity, not project rules.
Pick the right one
- Use
.hermes.mdwhen you want Hermes-specific behavior that lives above the cwd (root + subtree), or when you want rules to inherit from a parent directory. The parent walk stops at the git root, so a home-level.hermes.mdwon't leak into every project (a git repo's root is the boundary). - Use
AGENTS.mdwhen the same project will also be worked on by other agents (Codex, Claude Code, OpenCode). Those tools all have their own conventions forAGENTS.md, and the "cwd only" contract keeps the file portable. - Don't put project rules in
~/.hermes/AGENTS.md(or any other home-level location). When Hermes runs with that directory as cwd, the file loads — but only for that one directory. For cross-project context, useSOUL.md(in$HERMES_HOME, identity-only) or install a skill viahermes skills install.
Size and truncation
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.
Security
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.
Disable for one session
hermes --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.
Example: a small .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.
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
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:
hermes 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:
hermes config set security.redact_secrets false
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-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=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.

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_taskfor 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 -qfor fire-and-forget — no PTY needed - Use tmux for interactive sessions — raw PTY mode has
\rvs\nissues with prompt_toolkit - For scheduled tasks, use the
cronjobtool instead of spawning — handles delivery and retry
Durable & Background Systems
Four systems run alongside the main conversation loop. Quick reference
here; full developer notes live in AGENTS.md, user-facing docs under
website/docs/user-guide/features/.
Delegation (delegate_task)
Spawn a subagent with an isolated context + terminal session.
- Single:
delegate_task(goal, context). - Batch:
delegate_task(tasks=[{goal, ...}, ...])runs children in parallel, capped bydelegation.max_concurrent_children(default 3). - Background:
delegate_task(background=true)returns a handle immediately and keeps the parent loop going; the child's result re-enters the conversation as a new turn when it finishes. - Roles:
leaf(default; cannot re-delegate) vsorchestrator(can spawn its own workers, bounded bydelegation.max_spawn_depth). - Not durable. A backgrounded child is still process-local — if the
parent process exits, the child is lost. For work that must outlive
the process, use
cronjoborterminal(background=True, notify_on_complete=True).
Config: delegation.* in config.yaml.
Cron (scheduled jobs)
Durable scheduler — cron/jobs.py + cron/scheduler.py. Drive it via
the cronjob tool, the hermes cron CLI (list, add, edit,
pause, resume, run, remove), or the /cron slash command.
- Schedules: duration (
"30m","2h"), "every" phrase ("every monday 9am"), 5-field cron ("0 9 * * *"), or ISO timestamp. - Per-job knobs:
skills,model/provideroverride,script(pre-run data collection;no_agent=Truemakes the script the whole job),context_from(chain job A's output into job B),workdir(run in a specific dir with itsAGENTS.md/CLAUDE.mdloaded), multi-platform delivery. - Invariants: 3-minute hard interrupt per run,
.tick.lockfile prevents duplicate ticks across processes, cron sessions passskip_memory=Trueby default, and cron deliveries are framed with a header/footer instead of being mirrored into the target gateway session (keeps role alternation intact).

Background maintenance for agent-created skills. Tracks usage, marks idle skills stale, archives stale ones, keeps a pre-run tar.gz backup so nothing is lost.
- CLI:
hermes curator <verb>—status,run,pause,resume,pin,unpin,archive,restore,prune,backup,rollback. - Slash:
/curator <subcommand>mirrors the CLI. - Scope: only touches skills with
created_by: "agent"provenance. Bundled + hub-installed skills are off-limits. Never deletes — max destructive action is archive. Pinned skills are exempt from every auto-transition and every LLM review pass. - Cost: the deterministic inactivity/prune sweep runs for free. The
aux-model "consolidate overlapping skills into umbrellas" pass is
off by default — opt in with
curator.consolidate: trueorhermes curator run --consolidate. Routine background curation costs zero tokens. - Telemetry: sidecar at
~/.hermes/skills/.usage.jsonholds per-skilluse_count,view_count,patch_count,last_activity_at,state,pinned.
Config: curator.* (enabled, interval_hours, min_idle_hours,
stale_after_days, archive_after_days, backup.*).

Kanban (multi-agent work queue)
Durable SQLite board for multi-profile / multi-worker collaboration.
Users drive it via hermes kanban <verb>; dispatcher-spawned workers
see a focused kanban_* toolset gated by HERMES_KANBAN_TASK, and
orchestrator profiles can opt into the broader kanban toolset. Normal
sessions still have zero kanban_* schema footprint unless configured.
- CLI verbs (common):
init,create,list(aliasls),show,assign,link,unlink,comment,complete,block,unblock,archive,tail. Less common:watch,stats,runs,log,dispatch,daemon,gc. - Worker/orchestrator toolset:
kanban_show,kanban_complete,kanban_block,kanban_heartbeat,kanban_comment,kanban_create,kanban_link; profiles that explicitly enable thekanbantoolset outside a dispatcher-spawned task also getkanban_listandkanban_unblockfor board routing. - Dispatcher runs inside the gateway by default
(
kanban.dispatch_in_gateway: true) — reclaims stale claims, promotes ready tasks, atomically claims, spawns assigned profiles. Auto-blocks a task afterfailure_limitconsecutive spawn failures (default 2; configurable viakanban.failure_limitor per-taskmax_retries). - Isolation: board is the hard boundary (workers get
HERMES_KANBAN_BOARDpinned in env); tenant is a soft namespace within a board for workspace-path + memory-key isolation.

Surfaces & Other Capabilities
Beyond the CLI and gateway, a few things worth knowing about:
- Desktop app (
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. - Web dashboard (
hermes 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 embeddedhermes --tuichat. Secured behind an OAuth/token gate. - OpenAI-compatible proxy (
hermes proxy) — exposes ahttp://localhost:portOpenAI 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. - Automation Blueprints — pick a named automation and Hermes asks for what it needs (no cron syntax). One definition renders as a dashboard form, a slash command, an agent conversation, and a docs-catalog entry.
memorytool batch operations — pass anoperationsarray 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).- xAI Grok via SuperGrok OAuth — sign in with your xAI account (no API
key); includes Cursor's
grok-composer-2.5-fastcoding model.
Windows-Specific Quirks
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.
Input / Keybindings
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.
Config / Files
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;
hermes config edit writes correctly.
execute_code / Sandbox
WinError 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.
Testing on Windows
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.)
Path / Filesystem
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.
Troubleshooting
Voice not working
- Check
stt.enabled: truein config.yaml - Verify provider:
pip install faster-whisperor set API key - In gateway:
/restart. In CLI: exit and relaunch.
Tool not available
hermes tools— check if toolset is enabled for your platform- Some tools need env vars (check
.env) /resetafter enabling tools
Model/provider issues
hermes doctor— check config and dependencieshermes auth— re-authenticate OAuth providers (orhermes auth add <provider>)- Check
.envhas the right API key - Copilot 403:
gh auth logintokens do NOT work for Copilot API. You must use the Copilot-specific OAuth device code flow viahermes model→ GitHub Copilot.
Changes not taking effect
- Tools/skills:
/resetstarts 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
hermes skills list— verify installedhermes skills config— check platform enablement- Load explicitly:
/skill nameorhermes -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=truein/etc/wsl.conffor systemd services to work. Without it, gateway falls back tonohup(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.channelsevent. Without it, the bot ignores public channels. - Windows-specific issues (
Alt+Enternewline, WinError 10106, UTF-8 BOM config, test suite, line endings): see the dedicated Windows-Specific Quirks section above.
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>

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys) — both under $HERMES_HOME when it is set.
Adding a Tool
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.
Adding a Slash Command
- Add
CommandDeftoCOMMAND_REGISTRYinhermes_cli/commands.py - Add handler in
cli.py→process_command() - (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
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
- Tests auto-redirect
HERMES_HOMEto temp dirs — never touch real~/.hermes/. - The script probes
.venv, thenvenv, then the shared worktree venv. - Windows: the wrapper is POSIX-only; see the Windows-Specific Quirks section above for the direct-pytest workaround.
Cross-platform test guards: tests using POSIX-only syscalls need a skip marker. Common ones already in the codebase:
- Symlink creation →
@pytest.mark.skipif(sys.platform == "win32", reason="Symlinks require elevated privileges on Windows")(seetests/cron/test_cron_script.py) - POSIX file modes (0o600, etc.) →
@pytest.mark.skipif(sys.platform.startswith("win"), reason="POSIX mode bits not enforced on Windows")(seetests/hermes_cli/test_auth_toctou_file_modes.py) signal.SIGALRM→ Unix-only (seetests/conftest.py::_enforce_test_timeout)- Live Winsock / Windows-specific regression tests →
@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.
System prompt's execution-environment block
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.
Commit Conventions
type: concise subject line
Optional body.
Types: fix:, feat:, refactor:, docs:, chore:
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()fromhermes_constantsfor all paths (profile-safe) - Config values go in
config.yaml, secrets go in.env - New tools need a
check_fnso they only appear when requirements are met
