feat(sandbox): add encode_base64 opt-in to read_file tool with backward-compatible default#79
Conversation
- Modified read_file in CodeInterpreterToolSet to encode file content
as base64 by default; response includes 'encoding' field ('base64' or 'raw')
- Added optional 'raw' parameter (default False): when True, returns
plain text content unchanged
- Handles both str and bytes content from the underlying API
- Added unit tests covering base64 default, roundtrip, bytes input,
raw=True, and raw=False equivalence to default
- mypy type check passed (324 files, no issues)

@copilot 如果要保持向前兼容，是否应该默认原文，传入 base64 后使用 base64？ |
…se64 opt-in
- Default behavior now returns plain text (backward compatible with
callers that expected raw content from the original read_file)
- New encode_base64=True parameter opts into base64 encoding for
binary file support
- Response always includes 'encoding' field ('raw' or 'base64')
- Updated unit tests to reflect new API

已按此思路调整（commit
# 默认：原文（向前兼容）
result = toolset.read_file(path="/tmp/notes.txt")
# {"path": "...", "content": "hello world", "encoding": "raw"}
# 按需开启 base64（适合二进制文件）
result = toolset.read_file(path="/tmp/output.bin", encode_base64=True)
# {"path": "...", "content": "aGVsbG8=", "encoding": "base64"} |
