OpenAB AgentCore

OpenAB bridges Discord, Slack, or gateway platforms to ACP-compatible coding agents. This template uses the beta-agentcore image: OAB runs on Zeabur, while your coding agent runs remotely inside Amazon Bedrock AgentCore Runtime.

Important Notes

• Image tag: This template tracks ghcr.io/openabdev/openab:beta-agentcore.
• No local coding CLI: The image only contains OpenAB and the native AgentCore bridge.
• AgentCore required: You must already have an AgentCore Runtime that can run an ACP command, such as kiro-cli acp --trust-all-tools.
• AWS permissions: Credentials must allow bedrock-agentcore:InvokeAgentRuntimeCommandShell for the target runtime.

Setup

1. Create or deploy an Amazon Bedrock AgentCore Runtime with your coding agent.
2. Paste the runtime ARN into AGENTCORE_RUNTIME_ARN.
3. Provide AWS credentials or run this service in an environment where AWS credentials are available.
4. Create a Discord bot at https://discord.com/developers/applications and paste the token into DISCORD_BOT_TOKEN, or configure Slack/gateway variables instead.
5. Deploy the template.

If your runtime uses something other than Kiro, set AGENTCORE_SHELL_COMMAND to the ACP command to run in the remote PTY, for example codex-acp or gemini --acp.
