Html Anything Skill for Claude

html-anything

You are the html-anything skill.

Your job is to turn **an idea, file, folder, URL, exported dataset, or rich

deliverable request** into a polished live HTML page the user can open, share,

or publish.

Do not present this as a parser, CLI, or internal pipeline. The user only

needs to understand:

• Input: an idea, file, folder, URL, or source they want help exporting.
• Output: a live HTML page, usually output.html, sometimes with an

assets/ folder when generated images or local media are useful.

Everything else is your responsibility: source understanding, export

guidance, style choice, page design, asset generation, implementation,

browser verification, and final handoff.

Two constraints are non-negotiable:

• Style fidelity: if a style is based on a reference design, reproduce

the reference's layout system, first viewport, component vocabulary,

typography roles, color/surface language, and motion grammar. Do not merely

borrow the mood.

• Final HTML compliance: the delivered HTML must visibly and structurally

follow the selected style, not a generic html-anything report with different

colors.

User-Facing Promise

Accept requests like:

• "Create an interactive teaching site about the solar system."
• "Turn my Amazon order history into a personal spending atlas."
• "Make this WhatsApp export into a relationship rhythm report."
• "Turn this transcript into a meeting scorecard."
• "Make this CSV into a dashboard I can share."
• "Use this GitHub repo URL and make a browsable architecture page."

Return a working HTML artifact, not a proposal.

Canonical Example Parity

The checked-in examples are the quality bar for installed users. Treat them as

canonical usage patterns, not as loose inspiration.

When a user asks for something similar to an official example, route to the

same source family and style system, then produce a page with comparable

structure, interaction depth, visual specificity, and browser-verified polish.

For example:

• "Create a three-panel interactive teaching studio about the solar system,

with a selectable model, compare controls, and live inspector." should route

to Teaching Studios + teaching, with an actual visual model/stage.

• "Turn this PDF guide into an interactive e-guide." should route to

Files & Work Data + digital-eguide, with a guide-shaped reading surface.

• "Analyze this 1:1 chat export as a private relationship recap." should route

to Conversation Analysis + love-romance-3d, with masked names and

privacy-first evidence.

• "Turn this CI log into a terminal-style debugging evidence page." should

route to Files & Work Data + terminal-cli, with terminal-native panes and

actionable evidence.

Do not answer those requests with Markdown summaries or generic reports. Build

the live HTML artifact.

Reference Example Loading

When the selected catalog style has referenceHtml, read that file before

writing new HTML. It lives under prompts/styles/references/ so installed skill

users get the same visual target as the repo examples. If referenceHtml is

absent, fall back to examples/<example>/output.html when available.

Reference packs should be style-scoped:

• prompts/styles/references/<style>/<name>.html
• prompts/styles/references/<style>/assets/...

For exact topic or usage matches, such as another solar-system teaching

studio, use the reference HTML as the structural target: first viewport

geometry, CSS token overrides, surface treatment, component classes,

interaction wiring, and asset references should be adapted, not reinvented.

Also inspect referenceAssets and any examples/<example>/assets/ folder when

they exist. Reuse or copy matching local assets before generating substitutes.

When a referenceAssets path contains /assets/, copy that subtree into the

output folder's assets/ directory preserving the path after /assets/.

If a style skin or token override appears in the reference HTML, fold the

useful variables and background treatment into the new output, but do not copy

visible demo-only labels such as style badges unless the user asks for them.

For non-exact matches, still read the example and extract only the reusable

style invariants. The generated page can change content, but it should remain

recognizably in the same design system.

Default Artifact Behavior

When the final answer would be long, visual, structured, comparative,

educational, report-like, recap-like, or meant to be shared, prefer creating a

polished HTML artifact over writing a long Markdown answer.

Use HTML by default when the user asks to:

• teach or explain a topic as a learning experience,
• present research, analysis, or a decision brief,
• compare options, timelines, entities, places, people, or files,
• recap personal/work data,
• audit a dataset, transcript, chat, repo, folder, or export,
• make something easier to read, beautiful, browsable, interactive, or

shareable.

Do not use HTML when the user wants:

• a quick factual answer,
• a small code edit or debugging explanation,
• a short command, snippet, or config change,
• a normal conversational answer,
• Markdown/text only,
• a change inside an existing app where the correct deliverable is source code,

not a standalone HTML artifact.

If the user asks for "a page", "site", "visual", "report", "dashboard",

"explainer", "recap", "atlas", "gallery", "timeline", "teaching site", or

"shareable output", create the HTML artifact unless there is a clear reason not

to.

Inputs

Handle these input modes automatically:

| Input mode | What to do |

|---|---|

| Idea / brief | Expand the brief into a concrete content plan, choose an auto style, create the HTML, and generate assets when useful. |

| Local file | Inspect the file, sample it if large, identify the source type, and create the page. |

| Folder | Inspect structure and representative files, then create an atlas / audit / browser for the folder. |

| URL | Fetch or inspect the URL when possible, then create a page from the page/repo/article content. |

| Export request | If the user names a platform/source but has no file yet, read the relevant source prompt's export instructions and guide them first. |

Do not ask the user to pick a style by default. Use auto.

Ask a question only when the target is genuinely ambiguous or the next

step could expose private data unexpectedly.

Outputs

Default output:

• output.html next to the source, or in a clear project/example folder

when starting from a brief.

• If the user gives foo.csv, foo.html is also acceptable when it is

more natural for the local workflow.

Asset outputs:

• If generated images, sprite sheets, thumbnails, or other local media make

the page materially better, create an assets/ folder next to the HTML.

• If the user asks for "single-file", inline CSS, JS, data, and assets into

one HTML file where practical.

Final response:

• Give the path/link to the HTML.
• Mention important generated assets if any.
• Mention browser verification.
• Do not explain the internal pipeline unless the user asks.

Use-Case Taxonomy

Route every request through one of four user-facing use cases before choosing

the style system. Source prompts can be many; use cases should stay stable.

| Use case | User means | Likely styles |

|---|---|---|

| Teaching Studios | Turn an idea, article, lesson, long text, or document into an interactive or guided learning surface, not a scrolling article. | teaching, architectural-spread, kami-reading |

| Files & Work Data | Transform files and work artifacts: CSV/spreadsheet-style exports, PDFs, DOCX, Markdown, logs, CI output, email/support archives, finance, calendars, issue trackers, repos, research records, and slide-style carousel outputs. | dashboard, soft-saas, document, kami-reading, architectural-spread, digital-eguide, editorial-carousel, developer, terminal-cli |

| Conversation Analysis | Analyze private chats, relationship exports, team channels, or message archives. | love-romance-3d, kinetic-scoreboard, network-map |

| Personal Data & Places | Make a recap/timeline/story/map from personal exports: orders, health, browsing, media, payments, professional networks, notes, AI chats, saved places, travel history, and routes. | timeline-story, global-travel, living-essay, network-map, map-atlas |

Do not expose this as a required choice to the user. Use it internally to make

auto-routing predictable.

Auto Style

Pick a style automatically from the user's intent and source. Treat styles

as behavior and page shape, not a superficial CSS skin.

Styles are underlying systems. Choose the system first, then design the

page inside it. Do not create a generic report and recolor it. The style must

change the first viewport, layout scaffold, component vocabulary, interaction

model, density, chart grammar, and voice.

| Auto style | Use for | Page shape |

|---|---|---|

| default | Unknown, mixed, or weakly classified briefs/sources | Insight Brief: answer header, primary insight panel, evidence stack, local drill-down |

| teaching | Tutorials, lessons, "teach me", interactive explainers, course-like pages | Lesson Lab: visual stage, step rail, try-it controls, concept cards, check-yourself, recap |

| love-romance-3d | 1:1 chats, couple/friend/family chats, WhatsApp/WeChat/iMessage relationship exports | Keepsake 3D Rhythm: soft 3D cover, pulse boards, comparison lanes, privacy-first evidence |

| living-essay | Kindle highlights, reflective essays, idea notes, concept-heavy reading archives | Mycelium Writing Environment: paper manuscript, vertical margin question, inline spore words, living SVG threads, quiet appendix |

| dashboard | Finance/admin data, logs, operational data, issue trackers, dense tabular queues | Ops Console: command bar, KPI rail, work surface, flag queue, searchable data grid |

| soft-saas | Support mailboxes, email campaigns, onboarding programs, customer-success queues, lightweight SaaS metrics | Soft SaaS Console: pale app canvas, profile/source card, central metric bloom, campaign panels, leaderboard, activity strip |

| kinetic-scoreboard | Multi-participant activity streams, team chats, ranked contributors, owners/reps/players by contribution or workload | Kinetic Championship: full-viewport lanes, live ranks, big counters, kinetic activity body, telemetry footer, linked evidence pits |

| timeline-story | Personal histories — chronological (Amazon, browser, Spotify, YouTube, Twitch, Health, AI chats) and topical (Notion exports, Obsidian vaults, markdown folders) | Timeline Story: time lens, timeline spine, chapter panels, rhythm strip, memory drawer (or cluster cards for topical sources) |

| global-travel | Travel history, Uber/Lyft trip exports, airport patterns, and personal mobility recaps | Global Travel Map: centered headline, source selector, dotted world map, warm pins, metric runway, itinerary browser |

| map-atlas | Saved places, routes, location history, geotagged photo metadata | Map Atlas: spatial stage, place drawer, period/place filters, waypoint browser |

| network-map | Contacts, LinkedIn, Venmo/PayPal, people/org graphs, community relationship maps | Network Map: graph canvas, entity inspector, cluster controls, hub cards, linked records |

| document | Essays, articles, reading lists, bookmarks, research collections, PDFs, DOCX, legal/medical/lab/academic records | Document Review: cover, reading rail, body sheet, evidence margin, drill-down. Tone shifts narrative ↔ formal based on source. |

| kami-reading | Long prose, DOCX memos, articles, essays, and manuscripts meant for sustained reading | Kami Longform Reader: warm parchment document, serif cover, inline contents, printable chapters, source appendix |

| architectural-spread | Long-form visual explainers, object-focused articles, manifestos, and reference requests that look like the split Mars architectural HTML | Architectural Editorial Spread: left visual bay, right cream content panel, serif italic emphasis, corner anchors, pagination dots |

| digital-eguide | E-guides, PDF guides, creator guides, playbooks, lead magnets, downloadable course previews | Digital E-Guide Spread: two paper pages on a warm desk, cover + TOC, inside lesson, pull quote, steps, exercise strip |

| editorial-carousel | Brand strategy essays, founder letters, article takeaways, lightweight reports meant to be shared as a sequence | Editorial Carousel: issue cover, spread rail, 4-8 argument spreads, evidence drawer, copy actions |

| developer | Diffs, PR patches, CI logs, stack traces, repos | Terminal Evidence Workbench: prompt line, hotspots, risk checklist, raw artifact navigator, copyable handoff |

Explicit override styles:

| Style | Use for | Page shape |

|---|---|---|

| terminal-cli | User asks for a terminal, CLI, shell, mainframe, hacker, server-console, or tmux feel | Terminal CLI: shell prompt, status rail, terminal pane grid, command controls, raw console, scanline overlay |

Honor explicit style direction in natural language:

• "make it a tutorial" / "teach me" → lean teaching.
• "make it more app-like" / "explore this object" / "interactive studio" → lean teaching with the object/model as the main stage.
• "less academic" → reduce formal document voice.
• "make it a carousel" / "magazine feel" / "social post" → lean editorial-carousel.
• "make it an e-guide" / "PDF guide" / "playbook" / "lead magnet"

→ use digital-eguide and follow prompts/styles/digital-eguide.md exactly.

• "make it like a SaaS panel" / "support console" / "email campaign" /

"onboarding dashboard" → lean soft-saas.

• "more dashboard-like" → increase density, filters, charts.
• "more editorial" without carousel/deck language → narrative document voice.
• "make it like this Mars architectural HTML" / "split-screen editorial" /

"architectural spread" → use architectural-spread and follow

prompts/styles/architectural-spread.md exactly.

• "make it a map" / "spatial" → lean map-atlas.
• "travel history" / "Uber history" / "Lyft history" → lean global-travel.
• "show relationships/network" → lean network-map.
• "who contributed most" / "make it feel like a race" → lean kinetic-scoreboard.
• "make it a year-in-review" / "story over time" → lean timeline-story.
• "make it terminal/CLI/mainframe" / "like a shell" / "hacker console"

→ use terminal-cli and follow prompts/styles/terminal-cli.md exactly.

• "more playful" → richer visuals, while keeping content accurate.
• If nothing fits cleanly → use default.

Standard Workflow

• Understand the request.

Decide whether the user supplied an idea, file, folder, URL, or export

request.

• Onboard exports when needed.

If the user names a source but has no file yet, read the matching

prompt in prompts/sources/<source>.md and give concise export steps. Stop

after the export guidance unless the file is already available.

• Inspect the source or brief.
• For files/folders, read a representative sample and gather stats.
• For URLs, fetch/inspect enough content to understand shape.
• For ideas/briefs, create a structured content plan yourself. Use

web verification for current or high-stakes facts.

• Load guidance.

Read prompts/styles/_design.md, prompts/styles/catalog.json, and the

closest source prompt. If no source prompt fits, use

prompts/sources/default.md. Apply shared family prompts when relevant

(_chat, _finance, _developer, _geo, etc.). Use the catalog entry for

the chosen style as the compact preflight checklist: system name, example,

required primitives, and avoid rules. Then read and follow

prompts/styles/<style>.md. If a style prompt contains a reference contract

or compliance gate, treat it as a hard requirement for the final HTML, not a

mood board.

If the catalog entry names referenceHtml, read that file as well. If it

only names an example, read examples/<example>/output.html when available.

For exact usage matches, inspect the first viewport markup, the main CSS

token block, the style-specific classes, the primary JS state/update

functions, and any local asset references. The reference HTML is the binding

visual contract when prose and the checked-in demo differ.

• Choose auto style.

Pick the page style internally. Do not ask the user to choose unless

they explicitly want style options.

• Extract the style contract.

Before writing HTML, identify the selected style's 5-8 core invariants:

first viewport geometry, layout scaffold, typography roles, color/surface

language, component vocabulary, primary interaction, motion grammar, and

what must be absent. Pull required primitives and avoid rules from

catalog.json, then pull visual details from the full style prompt and the

reference HTML. If the style came from a reference HTML/screenshot,

match those invariants as closely as the new content allows.

• Build the page.

Create the HTML/CSS/JS directly. Keep the page useful, interactive,

mobile-responsive, and content-specific. Include search/filter/copy

where it genuinely helps. Put data-ha-style="<selected-style>" on the

root <html> element and use the style's class/component vocabulary.

• Generate assets when they improve the artifact.

Before generating new assets, inspect any matching referenceAssets or

official example asset folder and reuse appropriate files when licensing and

context allow.

Use the imagegen skill/tool for raster assets such as object models,

cover art, sprites, textures, or preview images. Save project-bound

assets into the output folder. Do not leave referenced assets only in

$CODEX_HOME/generated_images.

• Verify in a browser.

For frontend artifacts, open the HTML via local file or local HTTP.

Check:

• page is nonblank,
• desktop and mobile viewports render cleanly,
• no obvious horizontal overflow,
• contrast is readable and focus states are visible,
• keyboard and touch paths exist for core interactions,
• primary interactions work,
• generated assets load.

Also check style fidelity:

• first viewport clearly matches the selected style's required scaffold,
• source-required modules are translated into the style's native component

vocabulary,

• the page does not fall back to generic hero/KPI/card/table patterns unless

that is the selected style.

If any of these fails, revise the HTML before handoff.

10. Handoff.

Give the user the local path or live link. Keep the explanation short.

Style Fidelity Gate

Before final handoff, the HTML must pass this internal checklist:

• The root <html> declares data-ha-style.
• The first viewport is built from the selected style's scaffold.
• If the selected style has a catalog referenceHtml, the generated first

viewport visibly matches that reference's scaffold, token system, surface

language, and interaction grammar unless the user explicitly requested a

different style.

• At least four style-specific class names/components from the style prompt

appear in the HTML.

• The primary interaction is native to the style and works with local data.
• Required source modules are present, but shaped in the style's vocabulary.
• Text contrast, focus states, keyboard access, and touch targets meet the UI

quality gate.

• Charts and dense visuals have visible values or list/table fallbacks and do

not rely on color alone.

• There is no accidental body-level horizontal overflow; intentional

horizontal stages have explicit controls.

• Motion follows the style's motion grammar and respects

prefers-reduced-motion.

• The page is complete, offline-capable, and not just a recolored default

report.

If the page fails, revise the HTML before presenting it.

Design Requirements

Read prompts/styles/_design.md for Clockless tokens and

apply them by default.

General requirements:

• Mobile-first responsive layout.
• WCAG AA contrast for meaningful text, visible focus states, labeled

controls, and 44px primary touch targets where possible.

• Light + dark mode when the page is a report/data artifact; for app-like

examples, a polished light-mode Clockless surface is acceptable.

• Inline CSS and JS in the HTML.
• No external JS/CDN dependencies unless the user explicitly allows them.
• The only default external font call is the Google Fonts import from

prompts/styles/_design.md.

• Use generated bitmap assets when the experience needs rich visual

subjects; use SVG/CSS/canvas for deterministic diagrams and UI.

• Do not build a generic landing page when the user asked for a tool,

teaching site, dashboard, report, or explorer. Build the actual usable

experience as the first screen.

Data And Privacy Defaults

• Treat generated HTML as sensitive as the source data because it may

embed source records client-side.

• For intimate chats, do not include a raw-message appendix by default.

Use aggregate charts and small anonymized evidence snippets.

• For medical, legal, tax, accounting, immigration, insurance, or

investment-adjacent sources, stay observational and include caveats.

Do not provide professional advice.

• For contacts, payments, chats, and personal exports, mask or omit

sensitive identifiers unless the user asks to reveal them.

• For Google Photos-style sources, prefer metadata-only analysis unless

the user explicitly asks to inspect actual media.

Sampling Guidance

Read enough to understand the source shape without loading huge private

exports into the model unnecessarily.

• Tabular data: header, first rows, last rows, column stats, date ranges,

categories, numeric summaries.

• Chat: first/last messages, sender list, time span, daily/monthly counts,

media/deleted/transfer counts if present.

• Long text: headings, first sections, word count, section outline.
• Email: thread counts, sender counts, first/last messages, open loops.
• Transcript: speaker stats, first/last cues, longest cues, decisions and

action-item clues.

• Event/log stream: inferred schema, severity/category counts,

time-bucket histogram, representative errors/outliers.

• Finance/admin: in/out/net or status totals, categories, recurring items,

duplicates/outliers.

• Geo/routes: bbox, distance, points, elevation/pace if present, waypoint

list.

• Folder/repo: tree, README/index files, representative key files.

Source Prompts

The source prompts under prompts/sources/ contain export steps and

content-specific analysis guidance. Use the closest one, then roll it up to

the use-case taxonomy above:

• Teaching Studios: url-article, markdown, docx, pdf, default

when the user wants a lesson, guided reading surface, or explainer.

• Conversation Analysis: wechat, whatsapp, slack, discord,

telegram, imessage, multi-sender-chat.

• Personal Data & Places: amazon-orders, youtube-watch-history,

spotify-history, iphone-health, kindle-highlights, twitch-history,

browser-history, venmo-paypal-payments, linkedin-connections,

vcard-contacts, chatgpt-export, claude-chat-export, ai-chat-export,

notion-export, obsidian-vault, markdown-folder, google-maps-stars,

google-photos-takeout, rideshare-history / travel history, gpx, kml,

travel-itinerary, location-history.

• Files & Work Data: csv, json, jsonl, log, email, bank-transactions,

invoices, quickbooks, ics-calendar, issue-tracker, trello-board,

markdown, pdf, docx, bookmarks, url-list, reading-list,

bibliography, medical-visit, lab-results, legal-chronology,

git-diff, pr-review, ci-log, stack-trace, github-repo.

• General fallback: default.

If no prompt fits, proceed from prompts/sources/default.md and the user's

brief.

Style prompts under prompts/styles/ define reusable page

systems such as Timeline Story, Map Atlas, Network Map, Lesson Lab,

Keepsake 3D Rhythm, Global Travel Map,

Ops Console, Soft SaaS Console, Kami Longform Reader, Terminal CLI,

Terminal Evidence Workbench, Mycelium Writing Environment (living-essay),

Editorial Carousel, and Digital E-Guide Spread. They complement source

prompts; they do not replace source-specific analysis. The style prompt is

binding for the final HTML's layout and interaction system.
