- Post excerpt:
- Plannotator natively integrates with coding agent plan modes via hooks. The core feature set is the ability to annotate plans throughout the planning mode process. Users submitted a feature request to be able to annotate any file. This is what that does. More on how Plannotator works in the video demo here: https://www.youtube.com/watch?v=a_AT7cEN_9I
- Post excerpt:
- Plannotator opens a local diff viewer (git, jj, p4). You annotate lines, tokens, or comment on files, and when you're done they feed straight into your agent session; creating an automated feedback loop. It works on local diffs, commits, branches, worktrees, and GitHub/GitLab PRs. The PR view lets you annotate the descriptions and comments while also being a

# Design Brief: Dark Developer (with Gradient Glow)
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #0c0e16;
--surface: #1a1d28;
--foreground: #f4f5f8;
--muted-foreground: #9aa0ae;
--accent: #8b7cff;
--radius: 16px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #0C0E16 (~62%) · Surface #1A1D28 (~14%) · Text #F4F5F8 (~12%) · Muted Text #9AA0AE (~7%) · Accent #8B7CFF (~5%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Large Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Download App / Install Extension · Trust bar uses Customer / Press Logo Strip
- Headline hook: Category Positioning Anchor
- Hero components: Code & Terminal, Customer Logo Wall, Metrics Strip
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and customer / press logo strip.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring centered headline + cta layout and code block / terminal / cli visuals.
## Avoid
- Warm pastel backgrounds
- Playful cartoon illustrations
- Oversized pill buttons everywhere
Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
