Building an autonomous Slack agent with OpenCode
Short summary
Pipa is a Slack-native autonomous agent using OpenCode (reasoning), Inngest (scheduling), E2B (execution), and Composio (integrations). The architecture separates concerns: Slack for interface, OpenCode for agent logic, E2B sandboxes for execution, and Inngest for orchestrating triggers and retries. This pattern powers real systems at Duolingo (180+ MCP tools), Shopify (River), and Mintlify (docs agent).
- •Slack-native autonomous agent combining OpenCode, Inngest, E2B sandbox, and Composio integrations
- •Architecture separates interface (Slack), reasoning (OpenCode), execution (E2B), and orchestration (Inngest)
- •Production adoption by Duolingo, Shopify, and Mintlify validates the pattern for agent autonomy
