Module output 

Output helpers for CLI subcommands: aligned tables and JSON.

Functions

image_dimensions

(width, height) of a PNG or JPEG from its header bytes, without an image crate. None for anything else or a truncated header.

print_json

Print a serializable value as pretty JSON, followed by a newline.

print_table

Print rows as a simple aligned table.

terminal_width

Best-effort terminal width for human table formatting.

write_private_file

Write bytes to path and restrict it to the current user (0600 on Unix). Shared by the file-writing MCP tools; the cookie/fetch CLI writers follow the same contract.
