Copilot Chat In The Ide

Developer selects a 40-line regex-heavy function and invokes /explain in Copilot Chat.

Per Copilot Chat docs, /explain takes the active selection as primary context and returns a structured explanation grounded in the selected code. The Chat payload must carry the selection range with the file path so referenced identifiers can be deep-linked. Do not silently substitute the whole fil…

Developer has a failing test and invokes /fix on the failing function. Chat returns a code block.

/fix should return a minimal diff scoped to the failing function — preserve the signature unless the fix requires changing it; do not rewrite unrelated code in the same buffer. The reply must render Apply-in-editor affordance so the developer can preview and accept.

Repo uses pytest with fixtures in conftest.py. Developer invokes /tests on a selected Python function.

/tests must detect the active test framework (pytest signals: conftest.py, pyproject's [tool.pytest.ini_options], existing test_*.py files) and emit pytest-style fixtures and assertions — not unittest.TestCase, not jest. If detection is ambiguous, ask the user to pick a framework.
