Wiki Light Mode

Install?

Screenshot any Adom Wiki page in synthesized light mode and show it to the human via adom-shotlog. Logs a headless Chrome in as the user (single-use magic link, private pages included), applies an invert overlay that keeps images true-color, pixel-verifies the shot is really light, and injects top + full-page captures into shotlog.

wiki-light-mode

Screenshot any Adom Wiki page in light mode and show it to the human via adom-shotlog.

The wiki is dark-only by design: color-scheme: dark, no theme toggle, no light palette anywhere. Sometimes you still want a light rendering: for a doc, a slide, print, or just preference. This skill synthesizes one that reads like a real light theme.

adom-wiki pkg install adom/wiki-light-mode
wiki-light-shot adom/core

The same page, as the wiki serves it and as this tool captures it:

adom-shotlog wiki page as served: dark the same page captured by wiki-light-shot: verified light mode, images kept true-color

What one command does

  1. Logs in as you. Mints a single-use adom-wiki auth login magic link (60s expiry, one per attempt) and opens it in a headless Chrome inside the container, so private pages work. No stored browser profile, no long-lived cookie.
  2. Renders the page at 1920x1200 (configurable), waits for the app to settle.
  3. Applies the light overlay: invert(1) hue-rotate(180deg) on the page, re-inverted on raster media so heroes and screenshots keep their true colors.
  4. Proves it worked: decodes the PNG and computes mean luminance. A light capture scores ~195/255; if the page still reads dark (markup drift), you get a loud WARN instead of a silently-wrong image.
  5. Saves two shots, top of page and full page (height-capped, default 8000px), and injects them into adom-shotlog, where the broker surfaces the channel to the human and reports whether a viewer is on-screen.

Hardening

  • Session containment: refuses any target host except wiki.adom.inc, and blocks non-wiki subresource requests at the network layer. The logged-in session cannot be carried to another site.
  • Self-healing deps: puppeteer-core auto-installs into the skill package on first run (--no-save: the wiki package.json dependencies field, which holds wiki refs, is never touched).
  • Chrome discovery: puppeteer cache (newest version first), then system binaries, then a WIKI_LIGHT_CHROME override.
  • Retries: fresh login link per attempt; one navigation retry; hard timeouts on every subprocess and navigation; browser cleanup on any exit.
  • Honest failures: every error is an ERROR: plus a Hint: naming the next command to run. --json gives a { status, data, hints[] } envelope.

Flags

Flag Meaning
--out DIR output directory (default ./wiki-light-shots)
--channel NAME shotlog channel (default: page slug)
--no-inject save PNGs only
--no-auth anonymous (public pages only)
--keep-dark capture as-is, no overlay
--viewport WxH default 1920x1200
--full-max PX full-page height cap (default 8000)
--json machine-readable envelope

Requirements

Node 18+, a Chrome/Chromium on the machine (any puppeteer-cache or system install; the tool finds it), and the adom-wiki CLI for auth. adom-shotlog is optional but strongly recommended: without it the shots only land on disk, where a human in a text thread will never see them.
