Execute bash commands to explore the TypeScript SDK filesystem.

FILESYSTEM STRUCTURE:
The SDK is organized as an in-memory virtual filesystem at /sdk/ containing:
- README.md - Overview of all available functions organized by namespace
- {Namespace}/ - Directory for each namespace containing:
  - {functionName}.d.ts - TypeScript definition file for each function

EXPLORATION WORKFLOW:
1. List files: `ls` to see README.md and namespace directories
2. Read README: `cat README.md` to see all available functions
3. Search: `grep 'keyword' README.md` to find specific functions
4. Read types: `cat {Namespace}/{functionName}.d.ts` for detailed type information

COMMANDS:
- ls, cat, grep, find - Explore the filesystem
- All standard bash utilities for text processing
- Networking bash commands like `curl`, `ping`, etc. are unavailable.
Use bash to explore the SDK and write a script.

CURRENT WORKING DIRECTORY: /sdk/

IMPORTANT:
- This is a READ-ONLY virtual filesystem for SDK exploration
- Use this to discover available functions and their signatures
