Triage Analysis

Error Type: Missing system libraries in slim container image

Root Cause:
The workflow uses python:3.12-slim which does not include system libraries required by WeasyPrint. When the workflow attempts to generate a letterhead PDF, WeasyPrint fails to load required GLib/Pango libraries.

Error Message:

OSError: cannot load library 'libgobject-2.0-0': libgobject-2.0-0: cannot open shared object file: No such file or directory.

Context:

Container: python:3.12-slim (minimal Debian-based image)
Trigger: workflow_dispatch on main branch
Failing step: Generate letterhead reference (calls skills/letterhead/scripts/run.py)
WeasyPrint depends on: libcairo2, libpango-1.0-0, libgdk-pixbuf2.0-0, libglib2.0-0

Recommendation: @agent can fix by adding a step to install required system libraries before the "Install dependencies" step:

- name: Install system dependencies
  run: |
    apt-get update -qq && apt-get install -y -qq \\
      libcairo2 \\
      libpango-1.0-0 \\
      libgdk-pixbuf2.0-0 \\
      libglib2.0-0 \\
      > /dev/null

Alternative: Use python:3.12 (full image) instead of python:3.12-slim.

Fixed in commit 9d69fda. Added system dependency installation step to the workflow:

libpango-1.0-0, libpangocairo-1.0-0, libpangoft2-1.0-0
libgdk-pixbuf-2.0-0
libffi-dev, libcairo2
git (for checkout operations)

The next workflow run should succeed. Closing this issue.
