morgankrey 10504e3ce1 Improve docs AI readiness (#59577) ... Context This PR makes the Zed docs easier for AI tools, search crawlers, and users to consume without changing the visible docs content. The current production docs are primarily optimized for browser navigation. They do not expose first-class Markdown URLs, an `llms.txt` index, page-level copy affordances, or machine-readable freshness metadata that let users and agents grab clean, current page content. Changes - Generate Markdown copies for docs pages during the mdBook postprocess step, including `/docs/index.md` as an alias for Getting Started. - Generate `/docs/llms.txt` from the mdBook chapter list, grouped by `SUMMARY.md` sections and annotated with page frontmatter descriptions. - Generate `/docs/sitemap.xml` with `<lastmod>` values for every docs page. - Emit machine-readable freshness metadata in HTML via `last-modified` and `article:modified_time` meta tags. - Generate Cloudflare Pages `_redirects` for `.html`, extensionless, and `.md` redirect variants, with channel-aware docs destinations. - Add discovery hints for agents and crawlers: `rel="llms.txt"`, `rel="alternate" type="text/markdown"`, and a short generated `llms.txt` directive in copied Markdown pages. - Update the docs proxy so `Accept: text/markdown`, `/docs.md`, and direct `.md` requests can resolve to the generated Markdown artifacts. - Move primary docs content earlier in the HTML source while preserving the visible layout, so crawlers and agent scorers encounter the article before sidebar chrome. - Move the existing copy-as-Markdown control from the top navigation into the page-title row, using the generated Markdown alternate link as the source of truth. - Split AI-discovery artifact generation out of `docs_preprocessor/src/main.rs` into a focused module. Best Practices Adopted - Use `llms.txt` as a concise navigation index, not a dump of full page content. - Link to absolute, canonical Markdown URLs from `llms.txt`. - Preserve the docs hierarchy in `llms.txt` instead of emitting a flat sitemap-like list. - Include short per-link descriptions from existing metadata rather than inventing summaries. - Keep `llms.txt`, Markdown copies, sitemap data, redirects, and freshness metadata generated from the same mdBook source to avoid drift. - Advertise Markdown alternates with standard HTML metadata and same-origin URLs. - Support both explicit Markdown URLs and content negotiation for clients that prefer Markdown. - Keep browser copy behavior pointed at generated Markdown alternate links instead of duplicating route inference in JavaScript. - Keep the copy-as-Markdown affordance in the page title row without duplicating header chrome controls. Validation - `cargo check -p docs_preprocessor` - `cargo test -p docs_preprocessor` - `./script/clippy -p docs_preprocessor` - `mdbook build ./docs --dest-dir=../target/deploy/docs/` - `node --check docs/theme/plugins.js` - `pnpm dlx prettier@3.5.0 docs/theme/plugins.js --check` - `git diff --check` - Local artifact checks confirmed generated Markdown pages, `llms.txt`, `sitemap.xml` lastmod values, HTML freshness metadata, Markdown alternate links, redirect targets, and preprocessed action/keybinding tags resolve as expected. - Worker URL rewrite mock covered `/docs/`, `/docs.md`, `/docs/index.md`, extensionless docs routes, `.html` routes, `/docs/llms.txt`, and `/docs/sitemap.xml`. - High-effort adversarial subagent review found blockers around channel-aware redirects, shallow-checkout date fallback, file size, duplicated Markdown path inference, and process spawning. Those were addressed. Remaining Notes - Local `python -m http.server` does not emulate Cloudflare Pages pretty URLs, `_redirects`, or the docs-proxy Worker, so full local `afdocs` still cannot prove content negotiation end to end. - Existing production remains unchanged until this PR is deployed through the docs workflow. - Production baseline `npx afdocs check https://zed.dev/docs/ --fixes --verbose` still reports the original failures before this PR is deployed: 12 passed, 8 failed, 3 skipped. Release Notes: - Improved docs AI-readiness by adding machine-readable discovery, Markdown access, and freshness metadata. --------- Co-authored-by: Katie Geer <katie@zed.dev> Co-authored-by: Ben Kunkle <ben@zed.dev>		2026-07-08 20:54:51 +00:00
