"""Agent prompts must steer the fleet at the Makefile, not raw package managers.

`agents/prompts/teams/backend.md` used to literally instruct `uv run ruff ...`
(copied from the human-facing CLAUDE.md), so agents ran raw `uv run` and bypassed
the Makefile's `UV_NO_SYNC=1` + private `UV_CACHE_DIR` — the guard against the
concurrent-venv-corruption race. This grep invariant keeps the prompts honest:
no agent-facing prompt instructs a raw `uv run`/`pip`/`conda`/`poetry`, and the
backend standards block names the make targets.
