Essay Authoring Skill

When writing or editing an MDX essay for this site, follow these patterns to produce rich, scrollytelling-style content with sticky figures, callouts, and embedded media.

Article Structure

Every essay should use the Scene component to pair figures with text. Scenes create a two-column layout where the figure sticks to the viewport while the reader scrolls through the accompanying text. This is the core reading experience — articles without Scenes feel flat.

Scene component

<Scene figure={<MyFigure />} caption="Short description of the figure.">

## Section heading

Body text that scrolls alongside the sticky figure. Can include
multiple paragraphs, lists, callouts, etc.

</Scene>

Props:

• figure (required): A React SVG figure component. These live in components/mdx/figures.tsx.
• caption (optional): Short uppercase label below the figure.
• side (optional): "left" (default) or "right". Alternate sides for visual rhythm.

Rules:

• Alternate side="left" and side="right" across consecutive Scenes for visual variety.
• Each Scene should contain 1-3 sections of text — enough to scroll past the figure, but not so much the figure feels abandoned.
• The first Scene in an article should appear early (within the first 2-3 paragraphs) to establish the scrollytelling pattern.
• On mobile, Scenes stack vertically (figure above text), so content must make sense in both layouts.

Figure components

Figures are custom SVG React components in components/mdx/figures.tsx. They use a shared color constant object C:

const C = {
  paper: "#fbf6ec",
  ink: "#2a2521",
  inkSoft: "#4d4640",
  faint: "#8a7f74",
  rule: "#e8ddc8",
  peach: "#ffd6bf",
  butter: "#fbe7a6",
  sage: "#c8dcbf",
  lavender: "#dccaee",
  rose: "#f2c4cd",
  sky: "#bedcef",
  terracotta: "#d98a6b",
  moss: "#6c8a5e",
  plum: "#7a5d8c",
};

When creating a new figure:

1. Add it to components/mdx/figures.tsx using the C color constants.
2. Register it in components/mdx/mdx-components.tsx.
3. Use viewBox="0 0 320 320" as the default canvas size (square, fits the Scene column).
4. Use className="w-full" on the SVG.
5. Keep figures illustrative and diagrammatic — not decorative. They should teach something.

Existing figures for reference:

• PollingFigure — clock face with polling arrows (reactive loop)
• ProactiveFigure — world-to-agent push arrow
• TripleFigure — three circles (clock/listener/inbox) connected by dashed lines
• WebhookTaxFigure — list of webhook plumbing steps
• RuntimeFigure — architecture diagram with runtime at center
• PromptLayerFigure — two-layer diagram (prompt advises, runtime enforces)
• GapMapFigure — table-style comparison grid

Callout components

Use Callouts to surface key insights, asides, or further reading that break out of the main text flow.

<Callout tone="thought" label="Short label here">
Content goes here. Can include *markdown* and **formatting**.
</Callout>

Tones:

• "thought" — for key insights or "aha" moments
• "warm" — for human observations, ironies, or gentle critiques
• "cool" — for further reading, technical references, or next steps

Rules:

• Use 2-4 Callouts per essay. Too many dilutes their impact.
• Labels should be short (3-6 words) and intriguing.
• Don't use Callouts for content that should be in the main text. They're for insights that stand on their own.

PullQuote component

For a single memorable line that deserves emphasis:

<PullQuote>
The first time you add a webhook, it takes an afternoon. The third time — correctly — it takes longer than a sprint.
</PullQuote>

Use sparingly — one per essay at most.

Sidenote component

Some main text.<Sidenote>Aside that appears in the margin on desktop.</Sidenote>

Caution: Sidenotes use absolute positioning and can overlap body text below them. Only use when there is enough vertical space. If overlap is a risk, use a Callout instead.

Embedded media

iframes (LinkedIn, Twitter, etc.)

<iframe src="https://..." height="264" width="504" frameborder="0" allowfullscreen="" title="Embedded post"></iframe>

Place contextually near the content the embed illustrates.

Voice guardrails

Before publishing, check the essay against these anti-patterns. Each one slipped past earlier drafts and became a recurring tic across the series.

• "That is/That's the [noun]." Do not end paragraphs with short declaratives that name the thing the reader just read about. ("That's the gap." "That is the wedge.") They say nothing. Cut or integrate.
• Dramatic closers. No grand closing lines that could be taglines. End with a specific observation or nothing. The reader doesn't need a drumroll.
• Branded phrase repetition. "Clock, listener, inbox" at most 2-3 times per essay (except three-primitives.mdx). Vary with "the three primitives," "the runtime's core," or just describe the concept.
• Tricolon overuse. "Not X. Not Y. Not Z." at most once per essay. Multiple parallel structures with identical openings are an LLM tell.
• Em-dash density. 1-2 per section. Convert excess to commas, colons, parentheses, or restructure.

Checklist for every article

Before considering an article complete:

• At least 2 Scene blocks with figures (alternating sides)
• Figures are illustrative SVGs that teach, not decorate
• 2-4 Callouts with varied tones
• All external references are linked
• Internal essay references use relative paths (/posts/slug)
• No HTML entities — use real Unicode characters (—, ', ", etc.)
• No markdown tables — use HTML <table> elements
• Frontmatter summary uses plain text (no HTML entities)
• Card illustration added in components/card-illustrations.tsx for the post slug
• New figure components registered in components/mdx/mdx-components.tsx
• No "That is/That's the [noun]." declarative closers
• No dramatic mic-drop closing lines
• "Clock, listener, inbox" exact phrase used at most 2-3 times
• No more than one tricolon per essay
• Em dashes limited to 1-2 per section
• No "This matters because" sentence openers
• No "uncomfortable truth/math/pattern" labels
• No fabricated incidents, outages, or operational claims the founder didn't experience
