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.

This PR adds the ability to collapse section in the docs sidebar (which
are persistent until you close the tab), and some design facelift to the
docs, which makes its design close to the site as well as polishing up
many elements and interactions (like moving the search to a modal and
making the table of content visible in smaller breakpoints).

Release Notes:
- N/A
## Summary
Adds a "Copy as Markdown" button to the documentation toolbar that
allows users to easily copy the raw markdown content of any
documentation page.
This feature is inspired by similar implementations on sites like
[Better Auth docs](https://www.better-auth.com/docs/installation) and
[Cloudflare Workers docs](https://developers.cloudflare.com/workers/)
which provide easy ways for users to copy documentation content.
## Features
- **Button placement**: Positioned between theme toggle and search icon
for optimal UX
- **Content fetching**: Retrieves raw markdown from GitHub's API for the
current page
- **Consistent styling**: Matches existing toolbar button patterns
## Test plan
- [x] Copy functionality works on all documentation pages
- [x] Toast notifications appear and disappear correctly
- [x] Button icon animations work properly (spinner → checkmark → copy)
- [x] Styling matches other toolbar buttons
- [x] Works in both light and dark themes
## Screenshots
The button appears as a copy icon between the theme and search buttons
in the left toolbar.

This PR enables dark mode on the documentation. This is done without any
special plugins, just pure JavaScript and CSS variables. I may open
fast-follow PRs to fine-tune design and code details that haven't been
super polished yet. For example, when switching to dark mode, the
`class` attribute on the `html` tag would change immediately, whereas
other attributes such as `data-theme` and `data-color-scheme` would
require a full refresh. This seems to be resolved, but not 100%
confident yet.

Release Notes:
- Enabled dark mode on the documentation
This PR significantly expands the assistant documentation, breaking it
out into sections, adding examples and further documenting features.
This PR introduces a convention in docs for swapping keybindings for mac
vs linux:
`<kbd>cmd-enter|ctrl-enter</kbd>`
In the above example, the first will be shown for mac, the second for
linux or windows.
TODO:
- [ ] Fix table style (for `/assistant/configuration`)
- [x] Add script to swap keybindings based on platform
- It should take in this format: [`cmd-n` (mac)|`ctrl-n`(linux)] and
return just the correct binding for the viewer's platform.
- [ ] Add image/video assets (non-blocking)
Release Notes:
- Updated assistant documentation
