What it does This plugin keeps Claude Code’s output in plain language. It is built on the principles of the ISO 24495 series, the international plain language standards. You get three things: Five skills. Core plain language rules (Part 1), legal writing (Part 2), technical writing (Part 3), organisational roll-out (Part 4, provisional), and document design (Part 5, provisional). Claude activates the right one for the task. An advisory hook. After Claude writes or edits a markdown file, the hook audits it and reports rule counts in one line: sentence length, paragraph density, legalese terms, heading depth. It never blocks a write. Clean files produce silence. A per-project config switches it off. An output style. Every response follows the same rules the skills enforce: short sentences, active voice, front-loaded structure, one term per concept. How to install /plugin marketplace add GaZmagik/iso-24495 /plugin install iso-24495-plain-language@iso-24495 The skills work everywhere. The hook and the background corpus monitor need Bun. What it does not claim The full ISO texts are licensed and were not consulted. The plugin is built from the standards’ public principles. Those come from the freely published International Plain Language Federation framework. Every numeric rule is this project’s own proxy, not a clause of any standard. Nothing the plugin produces is a statement of ISO conformance. Repo: https://github.com/GaZmagik/iso-24495 This post follows the plugin’s rules. submitted by /u/gazmagik
