Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; reads ~/.codex paths.

This is edilsonvilarinho/usage-monitor's own configuration. It tells Codex and OpenCode how to work on usage-monitor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything usage-monitor configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

usage-monitor AGENTS.md 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 8d 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.

Build commands (Windows)

Todos os comandos usam gradlew.bat ou .\gradlew.bat no PowerShell:

gradlew.bat run                               % roda a app desktop
gradlew.bat desktopJar                        % gera o JAR executavel
gradlew.bat build                             % compila + roda checks
gradlew.bat allTests                          % suite agregada de testes
gradlew.bat desktopTest                       % testes JVM/Desktop
gradlew.bat desktopTest --tests "com.usagemonitor.domain.*"        % foco em domain/common tests
gradlew.bat desktopTest --tests "com.usagemonitor.presentation.*"  % foco em ViewModel/common tests
gradlew.bat desktopTest --tests "com.usagemonitor.ui.*"            % testes Compose Desktop
gradlew.bat createDistributable               % gera distribuicao desktop
gradlew.bat packageInstaller                  % gera instalador NSIS se o NSIS estiver instalado
gradlew.bat clean                             % limpa artefatos

Importante: a task raiz test nao existe neste projeto KMP. Use allTests, desktopTest ou build.

Chaves obrigatórias para MiniMax e DeepSeek:

Ao habilitar qualquer uma das duas em Configurações -> APIs, a aplicação abre um campo mascarado para a API key. A chave é persistida em ~/.usage-monitor/api-keys.json, com escrita atômica e acesso restrito ao usuário. As variáveis de ambiente não são lidas pela aplicação.

Architecture

Arquitetura em tres camadas com dependencia unidirecional: presentation -> domain <- data

Source set Platform Contents
commonMain shared domain + data (DTOs, mappers, repositories) + presentation/UI
desktopMain JVM only data sources locais com java.io.File, AutoStartManager, Main.kt (arranque), AppGraph.kt (DI) e hosts de janela
commonTest shared testes unitarios de domain, mappers e ViewModel
desktopTest JVM only testes de componentes Compose Desktop
installer Windows only scripts e assets do NSIS installer

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.
