TiDB Bazel Prepare Gate

Overview

Use this skill before build/test commands when you are unsure whether make bazel_prepare is required. Policy source: AGENTS.md -> Build Flow -> When make bazel_prepare is required. In normal coding loops, skip this skill unless one of the decision-rule triggers is likely present.

Inspect Local Changes

Run from repository root:

git status --short
git diff --name-status
git diff --name-status --cached
git ls-files --others --exclude-standard
git diff -U0 -- '*.go'
git diff -U0 --cached -- '*.go'

Decision Rules

Trigger conditions are defined in AGENTS.md -> Build Flow -> When make bazel_prepare is required. Compare the output from the commands above against those conditions.

For the top-level test-function trigger in existing *_test.go files, inspect added lines in git diff -U0 -- '*.go' and git diff -U0 --cached -- '*.go' output for patterns like:

+func TestXxx(t *testing.T) {

and treat that as requiring make bazel_prepare.

For import-section changes in existing Go files, inspect git diff -U0 -- '*.go' and git diff -U0 --cached -- '*.go' for added/removed import lines, for example:

+import (
-import "fmt"
+	"context"

and treat those changes as requiring make bazel_prepare.

If any condition matches, run make bazel_prepare. If none of the rules match, continue without make bazel_prepare and report the evidence.
