[Bug]: google-workspace skill setup.py fails — hermes_constants import + missing Google API deps

[jerome-benoit]

Bug Description

The google-workspace skill scripts (setup.py and google_api.py) cannot run with a standard python or python3 invocation:

1. setup.py imports hermes_constants at module level, which is only available inside the Hermes nix/pip environment — not on the system Python. The fallback (Path(__file__).resolve().parents[4]) assumes a specific directory layout that does not match the installed skill path (~/.hermes/skills/productivity/google-workspace/scripts/).

2. Neither script can install its own deps because the Hermes nix environment does not include pip or ensurepip. The _ensure_deps() auto-install in setup.py always fails with No module named pip.

3. google_api.py does NOT depend on hermes_constants (it uses os.getenv("HERMES_HOME")), creating an inconsistency between the two scripts in the same skill.

Steps to Reproduce

# System python — fails (no hermes_constants)
python3 ~/.hermes/skills/productivity/google-workspace/scripts/setup.py --check

# Hermes nix python — fails (no Google API deps, no pip)
$HERMES_PYTHON ~/.hermes/skills/productivity/google-workspace/scripts/setup.py --check

Expected Behavior

setup.py should work the same way as google_api.py — using os.getenv("HERMES_HOME") as fallback when hermes_constants is unavailable, and the Google API deps should either be bundled in the Hermes environment or the skill should document the correct invocation.

Actual Behavior

setup.py crashes with ModuleNotFoundError: No module named 'hermes_constants' on any Python that is not the Hermes package environment with the correct PYTHONPATH.

Affected Component

• Skills (skill loading, skill hub, skill guard)

Messaging Platform

N/A (CLI only)

Debug Report

N/A — this is a code-level issue visible by reading setup.py lines 31-37 vs google_api.py line 34.

Operating System

macOS (nix-managed Hermes installation)

Python Version

System: 3.9.6, Hermes env: 3.12.13

Hermes Version

0.9.0

Root Cause Analysis

setup.py lines 31-37:

try:
    from hermes_constants import display_hermes_home, get_hermes_home
except ModuleNotFoundError:
    HERMES_AGENT_ROOT = Path(__file__).resolve().parents[4]
    if HERMES_AGENT_ROOT.exists():
        sys.path.insert(0, str(HERMES_AGENT_ROOT))
    from hermes_constants import display_hermes_home, get_hermes_home

The fallback re-raises the same ModuleNotFoundError. Compare with google_api.py line 34:

HERMES_HOME = Path(os.getenv("HERMES_HOME", Path.home() / ".hermes"))

Additionally, Google API dependencies (google-api-python-client, google-auth-oauthlib, google-auth-httplib2) are not included in the Hermes nix environment, and the nix env lacks pip/ensurepip to self-install them.

Proposed Fix

1. In setup.py, replace the hermes_constants import with a fallback matching google_api.py:

try:
    from hermes_constants import display_hermes_home, get_hermes_home
    HERMES_HOME = get_hermes_home()
except (ModuleNotFoundError, Exception):
    HERMES_HOME = Path(os.getenv("HERMES_HOME", Path.home() / ".hermes"))
    def display_hermes_home():
        return "~/.hermes" if str(HERMES_HOME) == str(Path.home() / ".hermes") else str(HERMES_HOME)

2. Add google-api-python-client, google-auth-oauthlib, google-auth-httplib2 to the Hermes environment dependencies (nix or pip).
