List directory contents in tree structure. Use this instead of shell ls.
<when_to_use> Use LS when:
- Exploring project structure
- Finding what's in a directory
- Understanding folder organization
- Checking if files/directories exist
Do NOT use LS when:
- Finding files by pattern → use
glob - Searching file contents → use
grep - Reading file contents → use
view</when_to_use>
List src excluding tests:
path: "src"
ignore: ["*_test.go", "*.test.ts"]
For large projects, use `glob` to find specific files instead of browsing the entire tree.
