• uv pip install targets .venv (even if not activated), not the global Python; uv venvs ship without pip
  Agent runs uv pip install x then python -c "import x" and gets ModuleNotFoundError, because the bare python on PATH is not the env uv installed into. Fix: In projects prefer uv add requests (updates pyproject.toml +…

• TypeScript 7 ships as `typescript` with a `tsc` binary — stop installing @typescript/native-preview / running tsgo

• Go 1.24+: track dev tools with the go.mod `tool` directive and `go get -tool` instead of a blank-import tools.go
  Agents create a tools.go file with //go:build tools and blank imports ( "github.com/.../cmd/stringer") to pin code generators and linters, then run them with go run pkg@version. Fix: In //go:generate lines use go tool…
