Rule reference

Over a hundred rules come with an automatic fix. Preview them as a diff with custos fix --dry-run --diff, or apply them all at once.

custos fix

A single static Go binary with its own PHP parser and type inference. Files are analysed in parallel, each in one pass over its syntax tree.

Install

custos lsp shows diagnostics as you type and offers quick-fixes, fix-all and suppressions. It runs alongside your main PHP language server.

Editor setup

Text, JSON, Checkstyle, GitHub annotations and SARIF output. A baseline lets legacy projects report only new findings.

CI recipes

Rule IDs match Php Inspections (EA Extended), so your existing @noinspection comments keep working.
