BaseSandbox

Download multiple files from the sandbox. Implementations must support partial success.

Edit a file by replacing string occurrences.

Uses downloadFiles() to read, performs string replacement in TypeScript, then uploadFiles() to write back. No runtime needed on the sandbox host.

Execute a command in the sandbox. This is the only method concrete implementations must provide.

Structured glob matching returning FileInfo objects.

Uses pure POSIX shell (find + stat) via execute() to list all files, then applies glob-to-regex matching in TypeScript. No Python or Node.js needed on the sandbox host.

Glob patterns are matched against paths relative to the search base:

• * matches any characters except /
• ** matches any characters including / (recursive)
• ? matches a single character except /
• [...] character classes

Search for a literal text pattern in files using grep.

List files and directories in the specified directory (non-recursive).

Uses pure POSIX shell (find + stat) via execute() — works on any Linux including Alpine. No Python or Node.js needed.

Read file content with line numbers.

Uses pure POSIX shell (awk) via execute() — only the requested slice is returned over the wire, making this efficient for large files. Works on any Linux including Alpine (no Python or Node.js needed).

Read file content as raw FileData.

Uses downloadFiles() directly — no runtime needed on the sandbox host.

Upload multiple files to the sandbox. Implementations must support partial success.

Create a new file with content.

Uses downloadFiles() to check existence and uploadFiles() to write. No runtime needed on the sandbox host.
