## Skylark Design Documents

Changes to the Bazel build and extension language (Skylark) should go
through the [Skylark Design Process](/designs/skylark/skylark-design-process.html).

1. [Parameterized Skylark Aspects](/designs/skylark/parameterized-aspects.html).
2. [Declared Providers](/designs/skylark/declared-providers.html).
3. [Saner Skylark Sets](/designs/skylark/saner-skylark-sets.html).
