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 | $0.00000 | $0.02641 |
| Opus 5.5 | $0.00000 | $0.01056 |
| Sonnet 5.5 | $0.00000 | $0.00528 |
| Haiku 4.5 | $0.00000 | $0.00264 |
Grade A, and why
bos-code-quality 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.
BOS Code Quality
This skill activates during code review, PR review, quality checks, or when phrases like "check quality", "review code", "verify compliance", or "design system check" appear. Auto-activates after any UI component work.
Core Purpose
Ensure all code meets BOS (Brand Operating System) standards for design system compliance, accessibility, and brand consistency. This skill integrates with code reviews to add BOS-specific quality gates.
Quality Dimensions
1. Design System Compliance
Color Usage
✅ CORRECT ❌ WRONG
var(--bg-primary) bg-white
var(--fg-secondary) text-gray-500
var(--border-primary) border-slate-200
Verification Command:
# Find hardcoded colors (should return empty)
grep -rE "#[0-9A-Fa-f]{3,6}|rgb\(|rgba\(" --include="*.tsx" --include="*.css" | grep -v "var(--"
# Find forbidden Tailwind classes
grep -rE "bg-white|bg-black|text-white|text-black|border-white|border-black" --include="*.tsx"
Border Patterns (Style 2 Syntax)
// ✅ CORRECT - Subtle, supportive (Style 2 mapped classes)
className = 'border border-border-secondary hover:border-border-primary';
// ❌ WRONG - Harsh, dominant
className = 'border-2 border-white';
className = 'border border-brand'; // Never brand color for borders
Brand Color (Aperol #FE5102) Usage
ALLOWED FORBIDDEN
─────────────────────────────────────────────────────
Primary CTA buttons Borders
Active/selected states Backgrounds (except buttons)
Badge accents Decorative elements
Link hover states Large areas
2. Component Patterns
React Aria Requirement
All interactive elements MUST use React Aria Components:
// ✅ CORRECT
import { Button, Input, Select } from 'react-aria-components';
// ❌ WRONG
<button onClick={...}> // Missing accessibility
<input type="text" /> // Missing ARIA support
What ships with it
2 files 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.

bos-code-quality is a skill published in the GitHub repository opensesh/karimo-overview (11 stars, last pushed 5mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,641 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
