Two loadouts for the Markdown your agent writes. One is about voice: rules and a linter that catch 'seamlessly', 'not just X, it's Y', fake proof and em-dash runs in READMEs, pull requests and release notes. The other is about correctness: markdownlint-cli2, plus an offline check that relative links, images and heading anchors resolve and that every npm run command in the docs names a script that exists.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
Agent-written READMEs and docs checked offline: markdownlint-cli2, relative links and #anchors resolve, and every npm run command in the docs exists.
Rules and a linter that stop agents writing 'seamlessly empowers', 'not just X, it's Y', fake proof and em-dash runs into your docs, PRs and release notes.
