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 | $0.00054 | $0.01062 |
| Opus 5.5 | $0.00022 | $0.00425 |
| Sonnet 5.5 | $0.00011 | $0.00212 |
| Haiku 4.5 | $0.00005 | $0.00106 |
Grade A, and why
usage-monitor-design 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 yesterday.
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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Usage Monitor — design system
A fonte de verdade visual deste repositório é docs/design-system/.
Ela é normativa: divergência entre o Compose e o design system é defeito do Compose. A tabela
completa de precedência está em CLAUDE.md, seção Sistema visual → Design
system — precedência.
Antes de desenhar qualquer coisa
- Ler
docs/design-system/readme.mdinteiro. Ele carrega os fundamentos de conteúdo (voz, casing, "todo estado carrega uma palavra", "controle desabilitado sempre diz por quê") e as fundações visuais. - Ler os tokens em
docs/design-system/tokens/. Eles já têm equivalente exato em Kotlin —AppSpacing,AppShapes,AppElevation,AppMotion,AppThemePreset.OBSIDIANA_DARK/PORCELANA_LIGHTeAppAccentsemsrc/commonMain/kotlin/com/usagemonitor/presentation/ui/theme/. Não introduza um valor novo: se falta um degrau, a decisão vai para o design system antes de ir para o código. - Ler o contrato da primitiva que você vai usar em
docs/design-system/components/. Cada*.prompt.mddiz o que a primitiva resolve e o que é proibido dentro dela. - Abrir o mockup da tela no protótipo aprovado,
docs/planos/prototipo-visual-opencode.html, e o kit correspondente emdocs/design-system/ui_kits/desktop-app/.
Regras que não se negociam
- Nenhuma tela reimplementa uma primitiva. Antes de escrever
Surface,Card,Modifier.border,.backgroundcom cor de superfície ouRoundedCornerShape, procure empresentation/ui/components/AppStructure.kt,AppControls.kt,AppStates.kte nos vizinhosAppTabs.kt,AppSettingsNav.kt,AppSurfaceDepth.kt,AppChips.kt,AppMenu.kt,AppTooltip.kteAppStatusPill.kt. - Primitiva construída e não adotada não conserta nada. O commit que cria e o que consome são o mesmo.
- Cor de acento vem de
AppAccents.currenteAppTone, nunca dedarkAppAccents/lightAppAccentsdiretamente —valde topo de arquivo não lê o tema em vigor. - Cor nunca informa sozinha. Todo estado carrega ponto e palavra (
AppStatusIndicator). - Animação infinita só atrás de
AppMotionPolicy.continuous. Fora dela, trava owaitForIdledos testes de componente. Carregamento é esqueleto estático, sem shimmer e sem spinner. - Sem emoji. Os ícones são marcas Unicode em IBM Plex Mono, e a lista está no
readme.md. - Escala tipográfica fechada em 10/12/14/16/20/28; raio com teto de 10dp; elevação 8 só para janela, diálogo, menu e overlay.
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.

usage-monitor-design is a skill published in the GitHub repository edilsonvilarinho/usage-monitor (16 stars, last pushed yesterday), licensed MIT. It adds 54 tokens to every session and 1,062 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-16.
