Matrix Warnings

Manage "personal grudges" - warnings for problematic files or packages.

Parse user arguments from the skill invocation (text after the trigger phrase).

Use the matrix_warn tool with the appropriate action parameter.

Actions

List warnings (default, or "list"): Use matrix_warn with action: "list" to show all warnings.

• Optional: type: "file" or type: "package" to filter
• Optional: repoOnly: true to show only repo-specific warnings

Add warning ("add <type> <target> <reason>"): Use matrix_warn with action: "add" and:

• type: "file" or "package"
• target: file path/pattern or package name
• reason: why this is problematic
• severity: "info", "warn", or "block" (default: warn)
• repoSpecific: true if warning should only apply to current repo

Remove warning ("remove <target>" or "rm <target>"): Use matrix_warn with action: "remove" and either:

• id: the warning ID to remove, or
• type + target: to remove by type and target

Check target ("check <target>"): Use matrix_warn with action: "check" and:

• type: "file" or "package"
• target: file path or package name
