explainer-board-system is a skill in sirioberati/YouTube-AI-Motion-Graphics, last changed 27 Oct 2026. It can name web addresses.

From the author
The look, layout and motion system for 16:9 YouTube explainer boards, in the "Clean minimal" starter theme (white paper, thin-bordered cards with one soft shadow, Inter / JetBrains Mono / Instrument Serif, one blue accent, footage tiles at true aspect, camera box bottom-right). Use whenever you design, build, review or animate an explainer board, slide, chart, diagram or end screen; when someone asks for the board colours, fonts, sizes, safe zones, camera keep-out, chart rules, motion, easings or word-sync rules; when choosing which board fits a line ("which board for a price breakdown?"); or when QA-checking boards before export. It owns how boards look and move; explainer-board-brief owns what goes on them.

Pattern check

Pattern check: nothing flagged · commit 52b5b94 · 3 Nov 2026

We checked every text file in this skill, at commit 52b5b94 on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

  • Agent Skills specPasses

    The open format from agentskills.io, held to the strictest version of each rule among the agents we check.

    • Note

      The first sentence of the description is 278 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

    • Note

      There is no license field, so readers can't tell whether they may reuse the skill. O2

      Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/board-catalog.md (103 lines), references/charts.md (124 lines), references/components.md (197 lines) and references/motion.md (176 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude CodePasses

    Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

    • Note

      The first sentence of the description is 278 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/board-catalog.md (103 lines), references/charts.md (124 lines), references/components.md (197 lines) and references/motion.md (176 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude apps & API uploadPasses

    Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.

    • Note

      The description is 718 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4

      Fix: If the claude.ai upload refuses it, trim the description to 200 characters.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/board-catalog.md (103 lines), references/charts.md (124 lines), references/components.md (197 lines) and references/motion.md (176 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • OpenAI (Codex & API)Passes

    Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.

    • Note

      The first sentence of the description is 278 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

board-syncAnimate explainer boards to the presenter's voice. Takes the board HTMLs from Claude Design (04-boards), the final-cut WAV and its words.tsv, the marked script and the board brief; makes every element land on its spoken word; renders one clip per board and a full-length board-track.mp4; checks itself (qa-report.md with contact sheets); and writes the editor timeline for DaVinci Resolve (FCPXML) and Premiere (FCP7 XML) with the camera in the bottom-right zone. Step 5 of the explainer pipeline. Use when the editor says "animate the boards", "sync the boards to his voice", "board video", "render the boards", "build the editor timeline", re-runs one board after a fix, or asks why a board lands early, sits static or covers the camera zone. Runs end to end on Windows and Mac with one setup command (Python via uv, ffmpeg, the installed Edge or Chrome).

explainer-board-briefDecide WHAT goes on the explainer boards (slides, cards, diagrams) for a YouTube video script, before anyone designs them. Reads a pasted script line by line, finds every line, word, number and paragraph a viewer would not understand from the voice alone, groups them into one-picture boards, and writes a complete, never-empty brief that a board designer (the youtube-explainer-boards skill, Claude Design, or a human) can build from without guessing. Use whenever someone pastes or attaches a script and asks for boards, slides, a deck, visuals, diagrams, an explainer board plan, "what should go on screen", "which lines need a visual", a brief for Claude Design, or a check of whether existing boards are clear, empty or too wordy. Content only: it never chooses colours, fonts or layout styling. Runs end to end in any Claude account from a pasted script.
