Create professional, dark-themed architecture diagrams as standalone HTML files with SVG graphics. Use when the user asks for system architecture diagrams, infrastructure diagrams, cloud architecture visualizations, security diagrams, network topology diagrams, or any technical diagram showing system components and their relationships.

Use these semantic colors for component types:
| Component Type | Fill (rgba) | Stroke |
|---------------|-------------|--------|
| Frontend | rgba(8, 51, 68, 0.4) | #22d3ee (cyan-400) |
| Backend | rgba(6, 78, 59, 0.4) | #34d399 (emerald-400) |
| Database | rgba(76, 29, 149, 0.4) | #a78bfa (violet-400) |
| AWS/Cloud | rgba(120, 53, 15, 0.3) | #fbbf24 (amber-400) |
| Security | rgba(136, 19, 55, 0.4) | #fb7185 (rose-400) |
| Message Bus | rgba(251, 146, 60, 0.3) | #fb923c (orange-400) |
| External/Generic | rgba(30, 41, 59, 0.5) | #94a3b8 (slate-400) |
Use JetBrains Mono for all text (monospace, technical aesthetic):
<link href="https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@400;500;600;700&display=swap" rel="stylesheet">
Font sizes: 12px for component names, 9px for sublabels, 8px for annotations, 7px for tiny labels.
Background: #020617 (slate-950) with subtle grid pattern:
<pattern id="grid" width="40" height="40" patternUnits="userSpaceOnUse">
<path d="M 40 0 L 0 0 0 40" fill="none" stroke="#1e293b" stroke-width="0.5"/>
</pattern>
Component boxes: Rounded rectangles (rx="6") with 1.5px stroke, semi-transparent fills.
Security groups: Dashed stroke (stroke-dasharray="4,4"), transparent fill, rose color.
Region boundaries: Larger dashed stroke (stroke-dasharray="8,4"), amber color, rx="12".
Arrows: Use SVG marker for arrowheads:
<marker id="arrowhead" markerWidth="10" markerHeight="7" refX="9" refY="3.5" orient="auto">
<polygon points="0 0, 10 3.5, 0 7" fill="#64748b" />
</marker>
Arrow z-order: Draw connection arrows early in the SVG (after the background grid) so they render behind component boxes. SVG elements are painted in document order, so arrows drawn first will appear behind shapes drawn later.
Masking arrows behind transparent fills: Since component boxes use semi-transparent fills (rgba(..., 0.4)), arrows behind them will show through. To fully mask arrows, draw an opaque background rect (e.g., fill="#0f172a") at the same position before drawing the semi-transparent styled rect on top:
<!-- Opaque background to mask arrows -->
<rect x="X" y="Y" width="W" height="H" rx="6" fill="#0f172a"/>
<!-- Styled component on top -->
<rect x="X" y="Y" width="W" height="H" rx="6" fill="rgba(76, 29, 149, 0.4)" stroke="#a78bfa" stroke-width="1.5"/>
Auth/security flows: Dashed lines in rose color (#fb7185).
Message buses / Event buses: Small connector elements between services. Use orange color (#fb923c stroke, rgba(251, 146, 60, 0.3) fill):
<rect x="X" y="Y" width="120" height="20" rx="4" fill="rgba(251, 146, 60, 0.3)" stroke="#fb923c" stroke-width="1"/>
<text x="CENTER_X" y="Y+14" fill="#fb923c" font-size="7" text-anchor="middle">Kafka / RabbitMQ</text>
CRITICAL: When stacking components vertically, ensure proper spacing to avoid overlaps:
Example vertical layout:
Component A: y=70, height=60 → ends at y=130
Gap: y=130 to y=170 → 40px gap, place bus at y=140 (20px tall)
Component B: y=170, height=60 → ends at y=230
Wrong: Placing a message bus at y=160 when Component B starts at y=170 (causes overlap) Right: Placing a message bus at y=140, centered in the 40px gap (y=130 to y=170)
CRITICAL: Place legends OUTSIDE all boundary boxes (region boundaries, cluster boundaries, security groups).
Example:
Kubernetes Cluster: y=30, height=460 → ends at y=490
Legend should start at: y=510 or below
SVG viewBox height: at least 560 to fit legend
Wrong: Legend at y=470 inside a cluster boundary that ends at y=490 Right: Legend at y=510, below the cluster boundary, with viewBox height extended
<rect x="X" y="Y" width="W" height="H" rx="6" fill="FILL_COLOR" stroke="STROKE_COLOR" stroke-width="1.5"/>

development
Deep review of branch diffs, working trees, or GitHub PRs at any size. Use when the user asks for CodeRabbit-grade review, an incremental re-review after new pushes, publication of findings to a PR, a cross-LLM peer-review verdict round, or conformance review against spec artifacts. Don't use for applying fixes, reviewing specs or PRDs as documents, or quick single-file feedback.
tools
Orchestrate Claude and Codex worker TUIs from a controller agent through herdr panes and the herdr socket CLI. Use when delegating bounded tasks to herdr worker panes, running user-activated plan-first delegations (Claude Code plan mode, Codex Plan mode), waiting on native agent status (idle, working, blocked, done), or verifying worker reports. Workers launch as interactive TUIs via herdr agent start — never through headless runners (compozy exec, claude -p, codex exec). Not for cmux workspaces (see cmux-orchestration) and not for end-user herdr control.
tools
TanStack Query, Router, and Form patterns for React. Use when writing useQuery/queryOptions, mutations, caching, file-based routes, search params, loaders, or TanStack Form validation. Don't use for TanStack Start, TanStack DB/collections, Zustand client state, or non-TanStack routing.
development
Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary. Not for backend-only or non-UI tasks.
