AGENTS guide (concise, actionable)

Critical Importance

Keep responses short; show code over prose.
do not use getattr/hasattr and try/except blocks unless it really can't be avoided
if you already know an instance has certain attributes because of it's type, then don't check for the attributes
you must ask permission to use getattr/hasattr

Run tests isolated from external plugins: PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 pytest -q.
This only prevents third‑party plugin autoload; behavior is unchanged.
be sure to use @pytest.fixture markers on test data and locate fixtures in t/confest.py
try to re-use the fixtures as much as you can rather than always creating new ones.
when testing lots of really similar things, be sure to use @pytest.mark.parametrize

Build a light projection from common PagerDuty fields: id, status, severity/priority, service summary, created_at, assignments, alerts.
When listing things for the humans (--format text, etc); always try to align things vertically
a human's terminal is os.environ.get('COLUMNS', 80) wide
Use textwrap with break_long_words=False and break_on_hyphens=False to preserve URLs.
Do not allow word wrapping to break up markers like [status: triggered])
