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.

| charts | Chart and data visualization patterns for Remotion. Use when creating bar charts, pie charts, line charts, stock graphs, or any data-driven animations. |
|
Charts in Remotion
Create charts using React code - HTML, SVG, and D3.js are all supported.
Disable all animations from third party libraries - they cause flickering.
Drive all animations from useCurrentFrame().
Bar Chart
const STAGGER_DELAY = 5;
const frame = useCurrentFrame();
const { fps } = useVideoConfig();
const bars = data.map((item, i) => {
const height = spring({
frame,
fps,
delay: i * STAGGER_DELAY,
config: { damping: 200 },
});
return <div style={{ height: height * item.value }} />;
});
Pie Chart
Animate segments using stroke-dashoffset, starting from 12 o'clock:
const progress = interpolate(frame, [0, 100], [0, 1]);
const circumference = 2 * Math.PI * radius;
const segmentLength = (value / total) * circumference;
const offset = interpolate(progress, [0, 1], [segmentLength, 0]);
<circle
r={radius}
cx={center}
cy={center}
fill="none"
stroke={color}
strokeWidth={strokeWidth}
strokeDasharray={`${segmentLength} ${circumference}`}
strokeDashoffset={offset}
transform={`rotate(-90 ${center} ${center})`}
/>;
Line Chart / Path Animation
Use @remotion/paths for animating SVG paths (line charts, stock graphs, signatures).
Install: npx remotion add @remotion/paths
Docs: https://remotion.dev/docs/paths.md
Convert data points to SVG path
type Point = { x: number; y: number };
const generateLinePath = (points: Point[]): string => {
if (points.length < 2) return "";
return points.map((p, i) => `${i === 0 ? "M" : "L"} ${p.x} ${p.y}`).join(" ");
};
Draw path with animation
import { evolvePath } from "@remotion/paths";
const path = "M 100 200 L 200 150 L 300 180 L 400 100";
const progress = interpolate(frame, [0, 2 * fps], [0, 1], {
extrapolateLeft: "clamp",
extrapolateRight: "clamp",
easing: Easing.out(Easing.quad),
});
const { strokeDasharray, strokeDashoffset } = evolvePath(progress, path);
<path
d={path}
fill="none"
stroke="#FF3232"
strokeWidth={4}
strokeDasharray={strokeDasharray}
strokeDashoffset={strokeDashoffset}
/>;
Follow path with marker/arrow
import {
getLength,
getPointAtLength,
getTangentAtLength,
} from "@remotion/paths";
const pathLength = getLength(path);
const point = getPointAtLength(path, progress * pathLength);
const tangent = getTangentAtLength(path, progress * pathLength);
const angle = Math.atan2(tangent.y, tangent.x);
<g
style={{
transform: `translate(${point.x}px, ${point.y}px) rotate(${angle}rad)`,
transformOrigin: "0 0",
}}
>
<polygon points="0,0 -20,-10 -20,10" fill="#FF3232" />
</g>;
