ic

Use after editing any Bazel file — BUILD.bazel, MODULE.bazel (including bazel/rust.MODULE.bazel), or a .bzl file — to validate the change without paying for a full build, and to auto-format it.

Use when you need to run a command (build, test, tool) inside the IC dev container via ./ci/container/container-run.sh — including on a host that has Docker but not podman (set CONTAINER_RUNTIME=docker) — or when you need to keep a namespace.so devbox awake during long-running work.

Use this when asked to fix flaky bazel tests.

Use when you need to run a Bazel build or test outside DFINITY's internal infrastructure — i.e. without access to the internal remote cache / remote downloader (bazel-remote.idx.dfinity.network), e.g. on a personal machine, in a sandbox, or for a reproducibility check. Two ways: --config=local, or bypassing the workspace bazelrc.

Use this when asked to fix a Bazel build reproducibility / determinism issue — a target whose outputs differ between builds (e.g. across machines, users, or checkout locations), typically because something bakes an absolute build path or a timestamp into an artifact.

Guide the governance backend canister upgrade process — pick RC commit, determine targets, create proposal texts, submit proposals, create forum posts, schedule votes, and update changelogs.
