qzx checkSystemPath

What it does

Diagnoses the system PATH variable, lists broken or duplicate folders, and locates all instances of a binary

Command maturity: Alpha

Available for real use and feedback while its interface and behavior can still evolve. This is the current development-checkout assessment. Every future immutable release tag preserves the exact assessment shipped by that version. Available in PyPI 0.2.2.0.8. This page documents the 0.2.2.0.8 alpha development checkout.

Behavior and built-in protections

Inspects without changing state

Direct execution for this operation

Works without invoking native programs

Works without network access

No elevation required by design

Representative output example

This illustrative JSON is derived from the current implementation-backed result contract. It shows what the command can return without claiming a recorded execution; values vary with inputs, host, permissions, and optional tools.

Errors and limits

The public contract requires success=false and a descriptive message on failure. This catalog does not yet declare a command-specific error taxonomy; inspect the result and do not invent error codes.

QZX is alpha software. Optional dependencies, permissions, and host capabilities can change the result.
