Before Writing Any Test Code — Non-Negotiable Checklist

Run through this before creating or editing any file under test/:

1. Helpers first: Check test/db_test_helpers.py for existing factories (make_db, make_device_dict, insert_device_from_dict, DummyDB). Use them. If what you need doesn't exist, add it there — never define it locally in the test file.
2. MAC literals must be lowercase: Every MAC string in fixtures, parametrize, assertions, docstrings, and comments must be lowercase hex (e.g. aa:bb:cc:dd:ee:01). No exceptions.
3. Test file location: Place new tests under a subdirectory of test/ that mirrors the source path (e.g. test/scan/ for server/scan/). Don't add new files directly in test/ root - a handful of existing ones there (e.g. test_plugin_helper.py, test_wol_validation.py) predate this convention; that's not license to add more, but don't migrate them unprompted either.
4. No inline imports: All imports at the top of the file.

Before Acting on Any PR Comment

1. Load the code-standards skill — all code changes must comply with it before replying.
2. Load the testing-workflow skill — any test additions or changes must follow it.
3. Load any domain-specific skill relevant to the files being changed (e.g. database-patterns for DB writes, settings-management for config).

Comment Classification

For each comment, determine:

Acting on Comments — Step by Step

1. Identify all actionable comments before touching any file.
2. Load relevant skills to understand conventions that apply.
3. Prepare a plan — list each file and the exact change required.
4. Make changes one comment at a time — keep commits focused.
5. Run targeted tests after each change (testing-workflow skill).
6. Reply only after the commit is pushed. Include the short SHA.

Reply Guidelines

• Be concise. Do not summarize or restate the original comment.
• State what was done and (optionally) why.
• Include the short commit hash when relevant.
• Do not thank or compliment the reviewer.

What to Check After Every Batch of Changes

• MAC literals lowercase — grep for uppercase hex in every changed test file: grep -Pn '[0-9A-F]{2}:[0-9A-F]' test/ must be empty.
• No local DB helpers — no DummyDB, make_db, or inline DDL defined outside test/db_test_helpers.py.
• No inline imports — all imports at the top of the file.
• Tests live under a subdirectory of test/ matching the source path, not in test/ root.
• Secret scan before committing.

Stacked / Base-Branch Issues

When a PR targets a non-default branch (e.g. next_release):

• Do not retarget the branch yourself; note it in a reply so the author can do it from the GitHub UI.
• Check CI failures on the base branch first before checking your branch.
