LEIA ANTES de salvar textos, posts, JSONs ou strings que possam conter Emojis ou caracteres Unicode especiais no MySQL. Se não ler: o banco rejeita o UPDATE silenciosamente e o registro fica NULL/não persiste.

JSON seguro para MySQL utf8 de 3 bytes
⚡ Gatilho Obrigatório
- TRIGGER: Gravar dados textuais ricos, posts de redes sociais, feedbacks de usuários ou JSONs arbitrários em colunas MySQL.
- SKIP APENAS SE: Colunas estritamente numéricas, booleanas ou slugs ASCII controlados.
- CONSEQUÊNCIA DE IGNORAR: Falha silenciosa de gravação no MySQL (
Incorrect string value), perda irrecuperável de conteúdo digitado pelo usuário e campos persistidos como NULL.
- Enquanto a conexão usar
mysqli_set_charset(..., "utf8"), trate caracteres de 4 bytes como incompatíveis com gravação direta. - Codifique payloads JSON com
json_encode($dados, JSON_UNESCAPED_SLASHES). - Não adicione
JSON_UNESCAPED_UNICODE: os escapes\uXXXXmantêm o valor ASCII-safe ejson_decoderecompõe Unicode/emoji na leitura. - Verifique erro/linhas afetadas após INSERT/UPDATE; helpers legados podem falhar silenciosamente.
- Se a migration existe mas a coluna continua nula, investigue charset antes de concluir que o caminho de persistência não executou.
- Se o projeto migrar integralmente para
utf8mb4, reavalie esta compatibilidade antes de remover o padrão.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
