Hermes Agent

Consolidated Hermes internals

This umbrella also owns former narrow Hermes maintenance skills:

hermes-routing: configuring skill-router/project-router/skill-index mappings, especially Chinese trigger aliases and route misses.
hermes-s6-container-supervision: modifying or debugging the Docker image s6-overlay supervision tree, gateway/profile services, and Architecture B main-program patterns.

Full original packages are preserved under references/absorbed-skills/ for detailed recipes and support files.

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:

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, Signal, Matrix, Email, and 8+ other platforms with full tool access, not just chat.
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.

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_task for 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 -q for fire-and-forget — no PTY needed
Use tmux for interactive sessions — raw PTY mode has \r vs \n issues with prompt_toolkit
For scheduled tasks, use the cronjob tool instead of spawning — handles delivery and retry

Troubleshooting

Background process running but no output

Full fix reference: references/background-process-maintenance.md

Quick checks: inspect wrapper and child PIDs with ps/pgrep -P, use lsof for active sockets, and on macOS use sample <child-pid> 3 1 to distinguish sleep, network wait, and CPU loop. For long-running helpers, restart with python3 -u and explicit log-file writes under ~/.hermes/logs/ before every long sleep or request.

GPT model misroutes `read` instead of `read_file` (loop / hang)

Full fix reference: references/gpt-read-tool-misroute-failure.md

Quick fix: add alias mapping at gateway layer:

if tool_name == "read" and "path" in args:
    tool_name = "read_file"

Installing external skill repos (Aegis, Superpowers-style)

Full reference: references/aegis-multi-host-install.md

Pattern: clone repo → symlink into the target agent's skills dir only when explicitly requested → restart that agent. Keep Hermes routing/index as the control plane, and prefer direct runtime SKILL.md reads over mirrored host skill directories.

Voice not working

Check stt.enabled: true in config.yaml
Verify provider: pip install faster-whisper or set API key
Restart gateway: /restart

Tool not available

hermes tools — check if toolset is enabled for your platform
Some tools need env vars (check .env)
/reset after enabling tools

Third-party MCP server setup in Windsurf / VS Code-family IDEs

When a user asks to install or wire an external MCP server into Windsurf, GitHub Copilot in Windsurf, or another VS Code-family IDE, do not assume the same config schema everywhere.

Observed working pattern on macOS:

Windsurf reads ~/.codeium/windsurf/mcp_config.json
Windsurf expects top-level key mcpServers
HTTP servers use serverUrl, not VS Code's servers -> type: http -> url
Existing servers in that file should be preserved and merged, not overwritten blindly

Example Windsurf entry:

{
  "mcpServers": {
    "mcp-chat": {
      "serverUrl": "http://127.0.0.1:8080/mcp"
    }
  }
}

Contrast:

VS Code / GitHub Copilot examples may use ~/.vscode/mcp.json with:

{
  "servers": {
    "mcp-chat": {
      "type": "http",
      "url": "http://127.0.0.1:8080/mcp"
    }
  }
}

Do not paste this VS Code schema directly into Windsurf.

Python interpreter mismatch when launching external MCP/chat servers

If a cloned Python MCP/chat server appears to hang or not bind its port even though the process stays alive:

verify which python3 is actually being used
on macOS, /usr/bin/python3 may differ from Homebrew Python and lack the installed packages
a shell may resolve python3 differently from the package-install environment

Observed failure pattern:

background process remains running
no port is listening initially
no obvious logs surface
switching from system Python to Homebrew Python fixes startup

Practical check:

which python3
python3 -c 'import mcp, websockets; print("ok")'

If needed, launch explicitly with the interpreter that has the deps, e.g. /opt/homebrew/bin/python3 server.py.

Streamable HTTP MCP probe gotcha

Some streamable HTTP MCP servers require:

Content-Type: application/json
Accept: application/json, text/event-stream

If you POST initialize without the combined Accept header, the server may reply:

Not Acceptable: Client must accept both application/json and text/event-stream

Minimal probe:

curl -sS -X POST http://127.0.0.1:8080/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"probe","version":"1.0"}}}'

Use this to distinguish config/schema problems from transport/header problems.

macOS launchd for third-party local MCP/chat servers

When making a third-party local MCP/chat server persistent on macOS, prefer a per-user LaunchAgent over ad-hoc background shells.

Observed working pattern:

plist at ~/Library/LaunchAgents/<label>.plist
RunAtLoad + KeepAlive
explicit interpreter path (for example /opt/homebrew/bin/python3)
explicit WorkingDirectory
explicit log files in ~/Library/Logs/
if the server supports env-configured ports, set them in EnvironmentVariables

Skeleton:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

Load/reload:

launchctl bootout gui/$(id -u) "$HOME/Library/LaunchAgents/com.example.mcp-chat.plist" >/dev/null 2>&1 || true
launchctl bootstrap gui/$(id -u) "$HOME/Library/LaunchAgents/com.example.mcp-chat.plist"
launchctl kickstart -k gui/$(id -u)/com.example.mcp-chat

Verify:

launchctl print gui/$(id -u)/com.example.mcp-chat | sed -n '1,120p'
lsof -nP -iTCP:8090 -sTCP:LISTEN
curl -sS http://127.0.0.1:8090/v1/models

Important pitfall:

do not try to change the listen port only with launchd Sockets unless the app is socket-activation aware or actually consumes launchd-passed file descriptors
many Python servers still bind the port from their own code/config, so Sockets alone can leave launchd showing service name = 8090 while the app still serves 8080
prefer patching the app to read env vars like MCP_CHAT_PORT / MCP_CHAT_WS_PORT, then set those vars in the plist

Model/provider issues

hermes doctor — check config and dependencies
hermes login — re-authenticate OAuth providers
Check .env has the right API key

Changes not taking effect

Tools/skills: /reset starts a new session with updated toolset
Config changes: /restart reloads gateway config
Code changes: Restart the CLI or gateway process

Skills not showing

hermes skills list — verify installed
hermes skills config — check platform enablement
Load explicitly: /skill name or hermes -s name

Installing local GitHub skills when `hermes skills inspect/install <url>` does not support the repo

Some GitHub skill repos are not indexed by Hermes skill sources, so hermes skills inspect https://github.com/org/repo can return Could not find ... in any source even when the repo is valid.

Working fallback:

git clone https://github.com/org/repo /tmp/repo-review
# review README/SKILL/install/runtime first
mkdir -p ~/.hermes/skills/<category>
cp -R /tmp/repo-review ~/.hermes/skills/<category>/<skill-name>
hermes skills list | grep -i '<skill-name>'

If the repo ships a binary installer but release download fails, prefer a documented local build path (cargo build --release, etc.) over inventing a second install script. Keep copied runtime skill and installed binary separate: ~/.hermes/skills/... for the skill, ~/.local/bin/... for the executable.

Cross-agent output style normalization

When the user corrects global response format/style, align all active agent prompt surfaces instead of fixing only the current Hermes repo file. See references/cross-agent-output-style-normalization.md for the local Codex / Claude / OpenClaw prompt files and the verification search terms. In particular, do not keep forced bracketed audit fields in global prompt files unless the user explicitly asks for that structured protocol.

Skill context budget exceeded / target skill not visible

Symptom:

Hermes or a downstream agent reports something like Exceeded skills context budget of 2%
the visible skill list is truncated
the skill you need is installed locally but did not make it into the model-visible window

What it means:

this is usually a routing/exposure problem, not a missing-install problem
the agent cannot auto-discover every installed skill when the skill catalog is too large for the prompt budget

Fastest fixes:

Preload the exact skill explicitly:
- hermes --skills <exact-route>
- hermes --skills autonomous-ai-agents/hermes-agent,<exact-route>
In-session, force-load the skill with /skill <route> instead of relying on broad auto-discovery.
Reduce default routing exposure so fewer unrelated skills are described up front.
For repeated workflows, create a lighter profile with only the needed routing/skills enabled.

Where to tune:

~/.hermes/routing/skill-router.md
project-local .hermes/routing/project-router.md
~/.hermes/routing/skill-index.json
oversized skill descriptions/frontmatter that waste prompt budget

Practical guidance:

if a task repeatedly needs one specific skill, prefer explicit preload over hoping the global skill index will fit
if a downstream agent can read the Hermes routing files directly, prefer routing-first resolution over dumping a giant available-skills catalog into prompt context
if an external host agent can read the Hermes routing files directly, prefer routing-first resolution over dumping a giant available-skills catalog into prompt context
keep Hermes routing/index as the control plane; do not mirror Hermes skills into another host agent's skill directory unless the user explicitly asks for that shared-library behavior
after changing routing, index triggers, or skill mappings, restart or open a fresh session because external agents may cache the previous skill list

Common durable fix:

add hard first-load rules for Hermes/routing topics in skill-router.md
add project-specific overrides in project-router.md
add matching trigger phrases for aa/hermes-agent and the target runtime skill in skill-index.json
when the downstream agent still cannot read routing files, pass the exact resolved aliases and a compact routing instruction block inline

Bulk skill renaming / shortening

When a user asks to shorten or rename many local Hermes skills at once, treat it as a compatibility-breaking library migration, not a cosmetic edit.

Observed constraints:

Changing only frontmatter name: is insufficient; runtime lookup commonly depends on directory basename too.
Router and governance docs can pin explicit runtime names and must be updated in the same task.
Existing cross-agent consumers, shell snippets, and user muscle memory will break after aggressive shortening.
A partially interrupted bulk pass can leave the skill tree in a mixed state where some directory names are shortened but some name: fields still hold older names.
Tool surfaces that show numbered lines can contaminate copied skill files if that text is written back directly.

Safe pattern:

Inventory the current runtime tree under ~/.hermes/skills.
Derive a deterministic rename map with collision handling before mutating files.
Rename directory basenames and then rewrite each SKILL.md frontmatter name: to match the final basename.
In the same task, patch routing/governance/index docs under ~/.hermes/routing that mention the old runtime names.
Re-verify:
- every SKILL.md has a name: line
- every name: equals its containing directory basename
- no duplicate skill names remain
- high-value router docs no longer reference superseded names
If a file was rewritten from numbered tool output, strip injected N| prefixes before final verification.

Verification probe:

python3 - <<'PY'
import os, re, json, pathlib
root=os.path.expanduser('~/.hermes/skills')
seen={}; mism=[]; dups=[]; missing=[]
for dp, dn, fn in os.walk(root):
    if 'SKILL.md' not in fn:
        continue
    p=os.path.join(dp,'SKILL.md')
    txt=pathlib.Path(p).read_text()
    m=re.search(r'(?m)^name:\s*(.+?)\s*$', txt)
    if not m:
        missing.append(p)
        continue
    name=m.group(1).strip()
    base=os.path.basename(dp)
    if name != base:
        mism.append((p, name, base))
    if name in seen:
        dups.append((name, seen[name], p))
    seen[name]=p
print(json.dumps({
    'skills': len(seen),
    'missing_name': len(missing),
    'mismatches': len(mism),
    'duplicates': len(dups),
}, ensure_ascii=False))
PY

Pitfalls:

Do not trust stale counts from prior sessions; rescan the live tree first.
Do not stop after renaming directories; fix frontmatter and router docs in the same pass.
Do not copy text from line-numbered readouts back into SKILL.md verbatim.
If loaded skills disappear after the migration, first try the new shorter names rather than assuming the library is broken.

`hermes update` fails on dependency install

Common symptoms:

Failed to fetch: https://pypi.org/simple/...
tls handshake eof
fallback says optional extras failed, then base install fails
venv/bin/python: No module named pip
No matching distribution found for wheel while using a mirror

Fast recovery on macOS/Linux:

cd ~/.hermes/hermes-agent
source venv/bin/activate || true
python3 -m ensurepip --upgrade
PIP_INDEX_URL=https://pypi.org/simple PIP_TRUSTED_HOST=pypi.org python3 -m pip install --upgrade pip setuptools wheel
UV_INDEX_URL=https://pypi.org/simple ~/.local/bin/uv pip install -e . --quiet
hermes --version

If the machine has a bad global pip mirror, inspect and fix it:

python3 -m pip config list -v
nl -ba ~/.config/pip/pip.conf

If index-url points at a stale or incomplete mirror (for example Tsinghua tuna) and installs are failing, replace it with:

[global]
index-url = https://pypi.org/simple

Then verify:

python3 -m pip index versions wheel | head -n 5

Notes:

uv pip can succeed once UV_INDEX_URL is forced to PyPI even if global pip config is broken.
Missing pip inside the Hermes venv is recoverable with python3 -m ensurepip --upgrade.
When debugging install failures, check both network reachability to https://pypi.org/simple/... and local pip config before changing project code.

Gateway issues

Check logs first:

grep -i "failed to send\|error" ~/.hermes/logs/gateway.log | tail -20

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys).

Adding a Tool (3 files)

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 import in model_tools.py → _discover_tools() list.

3. Add to toolsets.py → _HERMES_CORE_TOOLS list.

All handlers must return JSON strings. Use get_hermes_home() for paths, never hardcode ~/.hermes.

Adding a Slash Command

Add CommandDef to COMMAND_REGISTRY in hermes_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

source venv/bin/activate  # or .venv/bin/activate
python -m pytest tests/ -o 'addopts=' -q   # Full suite
python -m pytest tests/tools/ -q            # Specific area

Tests auto-redirect HERMES_HOME to temp dirs — never touch real ~/.hermes/
Run full suite before pushing any change
Use -o 'addopts=' to clear any baked-in pytest flags

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() from hermes_constants for all paths (profile-safe)
Config values go in config.yaml, secrets go in .env
New tools need a check_fn so they only appear when requirements are met

Hermes Agent

Consolidated Hermes internals

This umbrella also owns former narrow Hermes maintenance skills:

hermes-routing: configuring skill-router/project-router/skill-index mappings, especially Chinese trigger aliases and route misses.
hermes-s6-container-supervision: modifying or debugging the Docker image s6-overlay supervision tree, gateway/profile services, and Architecture B main-program patterns.

Full original packages are preserved under references/absorbed-skills/ for detailed recipes and support files.

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, Signal, Matrix, Email, and 8+ other platforms with full tool access, not just chat.
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.

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_task for 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 -q for fire-and-forget — no PTY needed
Use tmux for interactive sessions — raw PTY mode has \r vs \n issues with prompt_toolkit
For scheduled tasks, use the cronjob tool instead of spawning — handles delivery and retry

Troubleshooting

Background process running but no output

Full fix reference: references/background-process-maintenance.md

GPT model misroutes `read` instead of `read_file` (loop / hang)

Full fix reference: references/gpt-read-tool-misroute-failure.md

Quick fix: add alias mapping at gateway layer:

if tool_name == "read" and "path" in args:
    tool_name = "read_file"

Third-party MCP server setup in Windsurf / VS Code-family IDEs

When a user asks to install or wire an external MCP server into Windsurf, GitHub Copilot in Windsurf, or another VS Code-family IDE, do not assume the same config schema everywhere.

Observed working pattern on macOS:

Windsurf reads ~/.codeium/windsurf/mcp_config.json
Windsurf expects top-level key mcpServers
HTTP servers use serverUrl, not VS Code's servers -> type: http -> url
Existing servers in that file should be preserved and merged, not overwritten blindly

Example Windsurf entry:

{
  "mcpServers": {
    "mcp-chat": {
      "serverUrl": "http://127.0.0.1:8080/mcp"
    }
  }
}

Contrast:

VS Code / GitHub Copilot examples may use ~/.vscode/mcp.json with:

{
  "servers": {
    "mcp-chat": {
      "type": "http",
      "url": "http://127.0.0.1:8080/mcp"
    }
  }
}

Do not paste this VS Code schema directly into Windsurf.

Python interpreter mismatch when launching external MCP/chat servers

If a cloned Python MCP/chat server appears to hang or not bind its port even though the process stays alive:

verify which python3 is actually being used
on macOS, /usr/bin/python3 may differ from Homebrew Python and lack the installed packages
a shell may resolve python3 differently from the package-install environment

Observed failure pattern:

background process remains running
no port is listening initially
no obvious logs surface
switching from system Python to Homebrew Python fixes startup

Practical check:

which python3
python3 -c 'import mcp, websockets; print("ok")'

If needed, launch explicitly with the interpreter that has the deps, e.g. /opt/homebrew/bin/python3 server.py.

Streamable HTTP MCP probe gotcha

Some streamable HTTP MCP servers require:

Content-Type: application/json
Accept: application/json, text/event-stream

If you POST initialize without the combined Accept header, the server may reply:

Not Acceptable: Client must accept both application/json and text/event-stream

Minimal probe:

curl -sS -X POST http://127.0.0.1:8080/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"probe","version":"1.0"}}}'

Use this to distinguish config/schema problems from transport/header problems.

macOS launchd for third-party local MCP/chat servers

When making a third-party local MCP/chat server persistent on macOS, prefer a per-user LaunchAgent over ad-hoc background shells.

Observed working pattern:

plist at ~/Library/LaunchAgents/<label>.plist
RunAtLoad + KeepAlive
explicit interpreter path (for example /opt/homebrew/bin/python3)
explicit WorkingDirectory
explicit log files in ~/Library/Logs/
if the server supports env-configured ports, set them in EnvironmentVariables

Skeleton:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>

  <key>ProgramArguments</key>
  <array>

    <string>/path/to/server.py</string>
  </array>

    <string>8090</string>
    <key>MCP_CHAT_WS_PORT</key>
    <string>8091</string>
  </dict>
</dict>
</plist>

Load/reload:

launchctl bootout gui/$(id -u) "$HOME/Library/LaunchAgents/com.example.mcp-chat.plist" >/dev/null 2>&1 || true
launchctl bootstrap gui/$(id -u) "$HOME/Library/LaunchAgents/com.example.mcp-chat.plist"
launchctl kickstart -k gui/$(id -u)/com.example.mcp-chat

Verify:

launchctl print gui/$(id -u)/com.example.mcp-chat | sed -n '1,120p'
lsof -nP -iTCP:8090 -sTCP:LISTEN
curl -sS http://127.0.0.1:8090/v1/models

Important pitfall:

do not try to change the listen port only with launchd Sockets unless the app is socket-activation aware or actually consumes launchd-passed file descriptors
many Python servers still bind the port from their own code/config, so Sockets alone can leave launchd showing service name = 8090 while the app still serves 8080
prefer patching the app to read env vars like MCP_CHAT_PORT / MCP_CHAT_WS_PORT, then set those vars in the plist

Installing local GitHub skills when `hermes skills inspect/install <url>` does not support the repo

Some GitHub skill repos are not indexed by Hermes skill sources, so hermes skills inspect https://github.com/org/repo can return Could not find ... in any source even when the repo is valid.

Working fallback:

git clone https://github.com/org/repo /tmp/repo-review
# review README/SKILL/install/runtime first
mkdir -p ~/.hermes/skills/<category>
cp -R /tmp/repo-review ~/.hermes/skills/<category>/<skill-name>
hermes skills list | grep -i '<skill-name>'

Cross-agent output style normalization

Skill context budget exceeded / target skill not visible

Symptom:

Hermes or a downstream agent reports something like Exceeded skills context budget of 2%
the visible skill list is truncated
the skill you need is installed locally but did not make it into the model-visible window

What it means:

this is usually a routing/exposure problem, not a missing-install problem
the agent cannot auto-discover every installed skill when the skill catalog is too large for the prompt budget

Fastest fixes:

Preload the exact skill explicitly:
- hermes --skills <exact-route>
- hermes --skills autonomous-ai-agents/hermes-agent,<exact-route>
In-session, force-load the skill with /skill <route> instead of relying on broad auto-discovery.
Reduce default routing exposure so fewer unrelated skills are described up front.
For repeated workflows, create a lighter profile with only the needed routing/skills enabled.

Where to tune:

~/.hermes/routing/skill-router.md
project-local .hermes/routing/project-router.md
~/.hermes/routing/skill-index.json
oversized skill descriptions/frontmatter that waste prompt budget

Practical guidance:

if a task repeatedly needs one specific skill, prefer explicit preload over hoping the global skill index will fit
if a downstream agent can read the Hermes routing files directly, prefer routing-first resolution over dumping a giant available-skills catalog into prompt context
if an external host agent can read the Hermes routing files directly, prefer routing-first resolution over dumping a giant available-skills catalog into prompt context
keep Hermes routing/index as the control plane; do not mirror Hermes skills into another host agent's skill directory unless the user explicitly asks for that shared-library behavior
after changing routing, index triggers, or skill mappings, restart or open a fresh session because external agents may cache the previous skill list

Common durable fix:

add hard first-load rules for Hermes/routing topics in skill-router.md
add project-specific overrides in project-router.md
add matching trigger phrases for aa/hermes-agent and the target runtime skill in skill-index.json
when the downstream agent still cannot read routing files, pass the exact resolved aliases and a compact routing instruction block inline

Bulk skill renaming / shortening

When a user asks to shorten or rename many local Hermes skills at once, treat it as a compatibility-breaking library migration, not a cosmetic edit.

Observed constraints:

Changing only frontmatter name: is insufficient; runtime lookup commonly depends on directory basename too.
Router and governance docs can pin explicit runtime names and must be updated in the same task.
Existing cross-agent consumers, shell snippets, and user muscle memory will break after aggressive shortening.
A partially interrupted bulk pass can leave the skill tree in a mixed state where some directory names are shortened but some name: fields still hold older names.
Tool surfaces that show numbered lines can contaminate copied skill files if that text is written back directly.

Safe pattern:

Inventory the current runtime tree under ~/.hermes/skills.
Derive a deterministic rename map with collision handling before mutating files.
Rename directory basenames and then rewrite each SKILL.md frontmatter name: to match the final basename.
In the same task, patch routing/governance/index docs under ~/.hermes/routing that mention the old runtime names.
Re-verify:
- every SKILL.md has a name: line
- every name: equals its containing directory basename
- no duplicate skill names remain
- high-value router docs no longer reference superseded names
If a file was rewritten from numbered tool output, strip injected N| prefixes before final verification.

Verification probe:

python3 - <<'PY'
import os, re, json, pathlib
root=os.path.expanduser('~/.hermes/skills')
seen={}; mism=[]; dups=[]; missing=[]
for dp, dn, fn in os.walk(root):
    if 'SKILL.md' not in fn:
        continue
    p=os.path.join(dp,'SKILL.md')
    txt=pathlib.Path(p).read_text()
    m=re.search(r'(?m)^name:\s*(.+?)\s*$', txt)
    if not m:
        missing.append(p)
        continue
    name=m.group(1).strip()
    base=os.path.basename(dp)
    if name != base:
        mism.append((p, name, base))
    if name in seen:
        dups.append((name, seen[name], p))
    seen[name]=p
print(json.dumps({
    'skills': len(seen),
    'missing_name': len(missing),
    'mismatches': len(mism),
    'duplicates': len(dups),
}, ensure_ascii=False))
PY

Pitfalls:

Do not trust stale counts from prior sessions; rescan the live tree first.
Do not stop after renaming directories; fix frontmatter and router docs in the same pass.
Do not copy text from line-numbered readouts back into SKILL.md verbatim.
If loaded skills disappear after the migration, first try the new shorter names rather than assuming the library is broken.

`hermes update` fails on dependency install

Common symptoms:

Failed to fetch: https://pypi.org/simple/...
tls handshake eof
fallback says optional extras failed, then base install fails
venv/bin/python: No module named pip
No matching distribution found for wheel while using a mirror

Fast recovery on macOS/Linux:

cd ~/.hermes/hermes-agent
source venv/bin/activate || true
python3 -m ensurepip --upgrade
PIP_INDEX_URL=https://pypi.org/simple PIP_TRUSTED_HOST=pypi.org python3 -m pip install --upgrade pip setuptools wheel
UV_INDEX_URL=https://pypi.org/simple ~/.local/bin/uv pip install -e . --quiet
hermes --version

If the machine has a bad global pip mirror, inspect and fix it:

python3 -m pip config list -v
nl -ba ~/.config/pip/pip.conf

If index-url points at a stale or incomplete mirror (for example Tsinghua tuna) and installs are failing, replace it with:

[global]
index-url = https://pypi.org/simple

Then verify:

python3 -m pip index versions wheel | head -n 5

Notes:

uv pip can succeed once UV_INDEX_URL is forced to PyPI even if global pip config is broken.
Missing pip inside the Hermes venv is recoverable with python3 -m ensurepip --upgrade.
When debugging install failures, check both network reachability to https://pypi.org/simple/... and local pip config before changing project code.

Config: ~/.hermes/config.yaml (settings), ~/.hermes/.env (API keys).

Adding a Tool (3 files)

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 import in model_tools.py → _discover_tools() list.

3. Add to toolsets.py → _HERMES_CORE_TOOLS list.

All handlers must return JSON strings. Use get_hermes_home() for paths, never hardcode ~/.hermes.

Adding a Slash Command

Add CommandDef to COMMAND_REGISTRY in hermes_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

source venv/bin/activate  # or .venv/bin/activate
python -m pytest tests/ -o 'addopts=' -q   # Full suite
python -m pytest tests/tools/ -q            # Specific area

Tests auto-redirect HERMES_HOME to temp dirs — never touch real ~/.hermes/
Run full suite before pushing any change
Use -o 'addopts=' to clear any baked-in pytest flags

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() from hermes_constants for all paths (profile-safe)
Config values go in config.yaml, secrets go in .env
New tools need a check_fn so they only appear when requirements are met
