Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.01839 |
| Opus 5 | $0.00028 | $0.00920 |
| Sonnet 5 | $0.00011 | $0.00368 |
| Haiku 4.5 | $0.00006 | $0.00184 |
Grade A, and why
architecture-diagram scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to architecture-diagram — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Architecture Diagram Skill
Create professional technical architecture diagrams as self-contained HTML files with inline SVG graphics and CSS styling.
Design System
Color Palette
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) |
Typography
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.
Visual Elements
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.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architecture-diagram is a skill published in the GitHub repository compozy/skeeper (85 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 1,839 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to architecture-diagram, differing in 0 lines, and is treated as a copy.
