Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

Measuring text in Remotion
Prerequisites
Install @remotion/layout-utils if it is not already installed:
npx remotion add @remotion/layout-utils
Measuring text dimensions
Use measureText() to calculate the width and height of text:
import { measureText } from "@remotion/layout-utils";
const { width, height } = measureText({
text: "Hello World",
fontFamily: "Arial",
fontSize: 32,
fontWeight: "bold",
});
Results are cached - duplicate calls return the cached result.
Fitting text to a width
Use fitText() to find the optimal font size for a container:
import { fitText } from "@remotion/layout-utils";
const { fontSize } = fitText({
text: "Hello World",
withinWidth: 600,
fontFamily: "Inter",
fontWeight: "bold",
});
return (
<div
style={{
fontSize: Math.min(fontSize, 80), // Cap at 80px
fontFamily: "Inter",
fontWeight: "bold",
}}
>
Hello World
</div>
);
Checking text overflow
Use fillTextBox() to check if text exceeds a box:
import { fillTextBox } from "@remotion/layout-utils";
const box = fillTextBox({ maxBoxWidth: 400, maxLines: 3 });
const words = ["Hello", "World", "This", "is", "a", "test"];
for (const word of words) {
const { exceedsBox } = box.add({
text: word + " ",
fontFamily: "Arial",
fontSize: 24,
});
if (exceedsBox) {
// Text would overflow, handle accordingly
break;
}
}
Best practices
Load fonts first: Only call measurement functions after fonts are loaded.
import { loadFont } from "@remotion/google-fonts/Inter";
const { fontFamily, waitUntilDone } = loadFont("normal", {
weights: ["400"],
subsets: ["latin"],
});
waitUntilDone().then(() => {
// Now safe to measure
const { width } = measureText({
text: "Hello",
fontFamily,
fontSize: 32,
});
});
Use validateFontIsLoaded: Catch font loading issues early:
measureText({
text: "Hello",
fontFamily: "MyCustomFont",
fontSize: 32,
validateFontIsLoaded: true, // Throws if font not loaded
});
Match font properties: Use the same properties for measurement and rendering:
const fontStyle = {
fontFamily: "Inter",
fontSize: 32,
fontWeight: "bold" as const,
letterSpacing: "0.5px",
};
const { width } = measureText({
text: "Hello",
...fontStyle,
});
return <div style={fontStyle}>Hello</div>;
Avoid padding and border: Use outline instead of border to prevent layout differences:
<div style={{ outline: "2px solid red" }}>Text</div>
