What it does

Stitched Full Page Capture is an agent skill from nirholas/three.ws. Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts (for example `agents/openai.yaml`, `demo/PROMPT.md` and `demo/expected-output.md`).

It sits in Game Development, covering 3D graphics and WebGL. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

When your agent uses it

  • Full-page screenshots are blank
  • Show a tiny content strip
  • Disagree with a working scroll video
  • Article evidence/section crops must be derived from a trustworthy full-page image

Example prompts

  • “/stitched-full-page-capture”

Requirements

  • Node.js

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Open the real page URL, not a marketplace thumbnail, cover image, remix page, or asset URL.
  2. Warm the page by scrolling from top to bottom once so lazy media and reveal sections mount.
  3. Return to the top.
  4. Scroll downward in viewport-sized or slightly-overlapping steps.
  5. Wait about 2 seconds after each scroll stop.
  6. Capture the settled viewport.
  7. Stitch the viewport captures vertically into one full-page image.
  8. Cut section crops from that stitched image, not from the native browser fullPage screenshot.
  9. Validate the stitched image against the representative still, MP4, and motion frames.

What it can do on your machine

Read from SKILL.md and the folder at commit ec8d1d2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Stitched Full Page Capture loads about 944 tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 361 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~944

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

Stitched Full-Page Capture

Overview

Use settled viewport screenshots instead of trusting one-shot browser fullPage captures. This is especially important for Framer pages and other lazy/scroll-animated sites where the MP4 can look correct while the tall screenshot is mostly blank.

Core Workflow

  1. Open the real page URL, not a marketplace thumbnail, cover image, remix page, or asset URL.
  2. Warm the page by scrolling from top to bottom once so lazy media and reveal sections mount.
  3. Return to the top.
  4. Scroll downward in viewport-sized or slightly-overlapping steps.
  5. Wait about 2 seconds after each scroll stop.
  6. Capture the settled viewport.
  7. Stitch the viewport captures vertically into one full-page image.
  8. Cut section crops from that stitched image, not from the native browser fullPage screenshot.
  9. Validate the stitched image against the representative still, MP4, and motion frames.

Reject a full-page candidate when it has blank/gray/white bands, very low visual content, missing lazy-loaded sections, an extremely narrow content column, or obvious disagreement with the scroll video.

Script

For daily UI inspiration articles, use the helper script from this skill directory when available:

bash
node <skills-root>/stitched-full-page-capture/scripts/stitch_full_page_capture.mjs \
  --manifest articles/YYYY-MM-DD-ui-inspiration-capture/manifest.json

The script:

  • reads items[].pageUrl, fullPageImage, and sectionImages;
  • opens each live page in Playwright Chromium;
  • warms lazy content by scrolling once;
  • captures settled viewport slices;
  • stitches slices into fullPageImage;
  • regenerates each existing section crop from the stitched image;
  • updates manifest.json with fullPageCaptureMethod: "stitchedViewportScreenshots", viewport, step, segment count, and corrected crop coordinates.

Useful options:

bash
--item 4              # repair only item 4, 1-based
--viewport 1440x1100 # default
--step 950           # default; use less than viewport height for overlap
--wait 2000          # ms to wait after each scroll stop
--quality 3          # ffmpeg JPEG quality, lower is better
Show full SKILL.md (124 more words)Show less

Validation

After capture or repair:

  • Inspect at least the page that was visibly wrong before.
  • Confirm sips -g pixelWidth -g pixelHeight full-page/*.jpg reports expected wide/tall dimensions.
  • Confirm the full-page image is not mostly blank and includes lower-page content.
  • Confirm section crop coordinates are contiguous and end at the full-page image height.
  • Run the project’s normal checks, for example:
bash
git diff --check -- articles/YYYY-MM-DD-ui-inspiration-capture/content.md articles/YYYY-MM-DD-ui-inspiration-capture/manifest.json
node scripts/check-ui-inspiration-duplicates.mjs articles/YYYY-MM-DD-ui-inspiration-capture/manifest.json
for f in articles/YYYY-MM-DD-ui-inspiration-capture/videos/*.mp4; do ffprobe -v error "$f" >/dev/null; done

Notes

  • The scroll video is evidence that the page can render during real scrolling, but it is not a substitute for full-page still evidence.
  • Native fullPage screenshots can still be saved as comparison candidates, but do not use them as source of truth unless they visually match the stitched capture.
  • For daily UI articles, update the manifest and commit only the repaired article assets and metadata.
