Style Codex — your code's real conventions, written up as a standards document

Drop your source files and the browser measures what the code actually does across nineteen convention categories — indentation, quotes, semicolons, brace placement, naming case per declaration kind, comment style, line length, function length, nesting depth, blank-line rhythm, imports — each with exact variant counts, the majority, a conformance percentage and every deviating line named by file and number. From those counts alone it writes a complete standards document, an .editorconfig and a deviations CSV, free and with no model call. The metered pass adds the wording, the rationale, the enforcement advice and the judgement about what is too split to codify — then every rule it wrote is reconciled against the counts in public: each measured category must be claimed exactly once, no rule may contradict its measured majority, and a conformance figure that drifts from the count is shown as written beside the corrected number. A derived work of the @github/write-coding-standards-from-file skill.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
