• reply_to_thread — Responde em uma thread existente
• read_thread — Lê mensagens de uma thread
• list_threads — Lista threads recentes do canal
• find_thread — Busca threads por tópico ou conteúdo

Formato de mensagem:

Usa templates handlebars configuráveis (ex: 🤖 *{{identity}}'s Agent* — {{message}})

Motivacao e Contexto

Permitir que agentes AI de diferentes desenvolvedores se comuniquem de forma assíncrona, coordenando trabalho cross-team via Slack threads. Complementa o agent-teams-lead (comunicação intra-time) com comunicação inter-times.

Como Isso Foi Testado?

• Testes Unitarios
• Testes de Integracao
• Testes e2e (playwright)
• Testes de Aceitacao (QA)
• Testes de Performance
• Outros (quais?)
• Nenhum (por que?) — TypeScript compila limpo, lint passa. Testes de integração requerem Slack bot token real.
