## Rules - One pass per finished file or batch, not per edit. Do not reload mid-session; run this once work is otherwise done. - Preserve nearest repository Markdown config and style convention; never impose this skill's style on a repo that already picked its own. ## README files - Always treat as human-facing. - New root README with no existing repo convention: start from self-contained template `templates/MAIN-README.md`. HTML comments mark required vs. optional sections, state the license-section rule, and instruct deleting the comments once filled. Drop unused optional sections cleanly (no placeholder/"N/A" text). ## AI-agent facing Markdown - No maximum line width. Do not break lines. - Optimize layout for AI-agent consumption. No decoration. ## Human-facing Markdown - One `#` per file, title only. - `##` sections wrapped above and below with an HTML-comment dash decorator, no blank line between decorator and heading: ```markdown <!-------------------------------------------------------------------------------------------------> ## Section title <!-------------------------------------------------------------------------------------------------> ``` - `###` is the deepest default level. Going past it needs a concrete reason (deep reference material). Avoid `####`+. - Skip decorators entirely on agent-facing (lint-only) files unless the file already uses them. - Never retrofit this style onto a repo whose Markdown already has an established heading convention. ## Linting - `skills/artifact-markdown/scripts/lint.sh <file>.md`. - `skills/artifact-markdown/scripts/lint.sh --recursive <directory>`. ## Boundaries - Format/lint checks do not prove factual accuracy, reachable external links, or good prose quality.
