# Features of the Dustin Edwards network > What this site and the programs behind it do: writing, pages and feeds, charts, design, AI agents, hosting and checks. Source: https://dustinedwards.info/features What this site and the programs behind it do, by job. Each card names the program that does it. For how this one site is built, see the [colophon](https://dustinedwards.info/colophon); for how the programs connect, the [map of systems](https://dustinedwards.info/systems). ## Writing and publishing How an article gets written, checked and published to any site in the network. - Drafts that stay yoursCarrel An AI's draft is saved beside the author's and never replaces it. - Checks that flagCarrel Checks and reviewers point out problems in a text. The author decides. - Preview from the live siteCarrel A preview is drawn by the site's own renderer, so it matches what readers get. - Publishing by roleCarrel Who may publish depends on role. An AI tool cannot publish while a flag is open. - First publication is the owner'sdustinedwards.info Making a post public for the first time is reserved to the owner. The code refuses an agent that tries. - Books and manuscriptsCarrel Books, chapters and scenes from a private manuscript repository, checked for continuity and timeline, exported to ePub and Word. - Media libraryCarrel Images are listed, imported and deleted, with alt text set for each. - WebmentionsCarrel Mentions of a post from other sites are reviewed and accepted or declined. - One publishing contractShared code Every site mounts the same API (site-api), so Carrel lists, edits and publishes on all of them the same way. - Scheduled updatesShared code A change to a live post can be set to apply later, and the site applies it on its own schedule. ## Pages, feeds and search engines What every site sends to readers, search engines and AI agents. - One markdown pipelinePrelum Every site renders its markdown the same way, with the same safety rules. - Alt text requiredPrelum An image with no alt text is refused. A decorative image says so. - Captions and transcriptsPrelum A video needs captions or a statement that it is silent. Audio needs a transcript. - Rich blocksPrelum Figures, galleries, callouts, collapsible details, FAQs, link cards and buttons. - Math and codePrelum Equations, and highlighted code with a file name and marked lines. - Diagrams drawn aheaddustinedwards.info Diagrams are drawn at build time, one for the light theme and one for the dark. - Light embedsPrelum YouTube, Spotify, Apple Podcasts and other players load only when a reader presses play. - A markdown copy of every pagePrelum Add .md to a page's address, or ask for markdown, and you get the source the page was drawn from. - llms.txt and llms-full.txtPrelum A guide for AI agents, and every post in one file. - FeedsPrelum RSS, Atom and JSON feeds, for the whole site and for each tag and series. - SitemapsPrelum Sitemaps that list each page's images and the date each page last changed. - Search engine pingsPrelum IndexNow tells search engines when a page changes. - Structured dataPrelum schema.org markup and the page's head tags, written the same way on every site. - Crawler rulesPrelum robots.txt and ai.txt, naming search and AI crawlers and what each may do. - Site auditsPrelum A crawler checks a site's pages, and its icons and manifest, against the shared rules. - Search without a databasePrelum A small index ships to the browser, for a site that has no database to search. ## Charts and figures Charts that arrive with the page and can be read by everyone. Enarratio is an early alpha. - Drawn on the serverEnarratio A chart is drawn into the HTML, so it shows without JavaScript and search engines can read it. - Words and numbersEnarratio Every chart has a text alternative its author writes and an equivalent data table. - Light and darkEnarratio Colors come from the theme's stylesheet, so a chart follows the theme without being redrawn. - Runs anywhereEnarratio Node.js, Cloudflare Workers, Deno and Bun. Built on Observable Plot. - Astro and EmDashEnarratio enarratio-astro puts charts in Astro pages and Markdown, and enarratio-emdash adds a Chart block to EmDash's editor. - The network's lookCapsomer Capsomer gives every chart the shared colors, gridlines and behavior. ## Design One set of parts, so a fix in one place reaches every site. - Plain CSS, no frameworkCapsomer Color tokens, spacing and type are plain CSS that any site can use. - A color family per siteCapsomer Each site has its own family of colors, drawn from the same tokens. - Light, dark and higher contrastCapsomer Every color has a light, a dark and a higher-contrast value, and every pair is measured against its minimum. - More than 80 componentsCapsomer Tables, dialogs, menus, tabs, forms, date pickers, a command menu, a media library and more. - Shared header and footerCapsomer The same letterhead header and footer on every site, each in its own color. - Admin partsCapsomer An admin shell, a permission matrix, a moderation queue and a publish gate. - A markdown editorCapsomer An editor with draft comparison, for the admin pages that write. - The map of systemsCapsomer Draws the network as hexagons, or as a plain map of cards, from Capsid's public data. - A page of statesCapsomer Every component is shown in every state on Capsomer's own site. - No flash of the wrong themedustinedwards.info The theme is chosen on the server, and the toggle works with scripting off. ## Memory and work for AI agents Capsid keeps what earlier sessions settled and hands out work, with a record of who did what. - A versioned knowledge baseCapsid Documents live in namespaces, each change keeps the old version, and any version can be restored. - Search by words and by meaningCapsid Keyword search and semantic search work together over every document. - A briefing at the startCapsid A new session opens with its project's conventions and the documents every agent reads first. - A queue of signed jobsCapsid A job's text is signed when posted, so a changed job is refused. An agent claims it and finishes with a pull request. - Claims checked against GitHubCapsid Capsid stores what an agent said it did beside what GitHub confirms. - A key and a scope per agentCapsid Each agent has its own key and its own list of allowed projects, repositories and actions, checked in one place. - GitHub through an AppCapsid Capsid reaches GitHub as an App, so it holds no long-lived GitHub token. - Merge, close and releaseCapsid Pull requests can be merged or closed, branches deleted, commits tagged and releases published, by agents allowed to. - Auto-merge by signed policyCapsid A policy only the administrator can sign decides which pull requests may merge without a person. - An audit logCapsid Every change and delete is recorded with who made it. - Site watcherCapsid Reads each site's health page, CI status, deploys and live responses, and repairs drift. - Session telemetryCapsid Per-session summaries and cost and token totals for each job. It stores no prompts or replies. - The PortalCapsid The owner's dashboard: items waiting, site health, the job queue, open pull requests and deploys. - Public model and explorerCapsid A daily public model of the network and a public explorer that draws it. - Run a site from a chatdustinedwards.info An admin server lets the owner work with this site's registry, citations and lab procedures from a conversation. It cannot write or publish posts. - A study of its own useCapsid A public harness compares Claude Code with and without Capsid on the same tasks, scored on hidden tests. ## Hosting, safety and backups What every site gets from shared code, so each is run the same way. - Security headersShared code A content security policy and the other headers, with a report endpoint. - Rate limitsShared code One rate limiter for every site, with a version that counts exactly. - Sign-inShared code One sign-in flow for members, and a check that an Access application lets in exactly the site's admins. - A health reportShared code Every site answers /health in one format, and Capsid reads it. - Responsive imagesShared code Images are resized to the reader's screen on request, and edits such as a crop are applied the same way everywhere. - SpeedShared code Link prefetching, preloads and early hints, an edge page cache and a Server-Timing header. - Share cardsShared code The preview image a page shows when it is shared. - Bot checks and emailShared code A Turnstile check on forms, one way to send email and a security.txt file. - Checks on AI-written proseShared code A check on prose written with AI, and a measure of an author's voice. - Per-table backupsShared code d1-dump copies each table to the site's own storage on a schedule and works on databases with full-text search, where D1's own export does not. - Restore into a copyShared code A backup restores into a copy you can inspect first, and the age of the newest backup shows on the health page. - A copy outside CloudflareCapsid Every site's exports are copied to a locked Amazon S3 bucket in another account, with a markdown mirror of every Capsid document. ## Building and checking How a change is tested before it reaches a reader. - The same checks everywhereShared code devkit runs one set of pull request checks: workflow audits, dependency scans, bundle size, bloat and an automatic reviewer. - A shared-code checkShared code A repository that copies something a shared package already provides fails, so a fix is made once. - Update rulesShared code One dependency update policy, used by every repository. - Deploys that roll backShared code A deployed Worker is checked live and rolled back if the site refuses it. - Checks for the project's own claimsdustinedwards.info The colophon's list of what the site does is held to the code by checks that fail when a claim's anchor is gone. - Accessibility in the builddustinedwards.info Contrast, alt text, keyboard use and reading without script are tested, and the accessibility page names each check. ## On dustinedwards.info What a visitor can use here. - Publicationsdustinedwards.info Each paper has a page, with BibTeX, RIS and JSON downloads. - Lab calculatorsdustinedwards.info Titer, dilution, webbed plate, multiplicity of infection, efficiency of plating and lysate volume. - Protocolsdustinedwards.info Procedures with versions and a printable sheet, downloadable as CSV and JSON. - A lab registrydustinedwards.info A fact is stored once, in a record, and every page draws it from there. - Phage recordsdustinedwards.info A catalog of phages with a section for each. - The CVdustinedwards.info With its charts, a markdown copy and a PDF made on each save. - Search and Askdustinedwards.info Keyword search by section, and a streamed AI answer with citations that link to the passage. - Search from an AI tooldustinedwards.info The same search is open to AI tools over the Model Context Protocol. - How it is builtdustinedwards.info The colophon lists every resource, check and dependency, generated from the code.
