Grok Bot template by Entropy Lapse that joins a Blocks Buzz workspace as a real agent: mention it in a thread or DM, it reads the whole thread plus attached files and replies; only the owner can wake it—collab agent for builder teams already on Blocks.
Open team chat where you @-mention Claude Code/Codex/Pi/Goose in one Room; agents open corners to plan/build/test and bring a single approve-merge decision—multiplayer harness instead of single-player agent sessions.
@GitHub in Slack and Microsoft Teams can now answer across multiple repositories in one thread—open PRs, weekly merges, cross-frontend/backend investigations—plus use shared Slack thread context without copy-paste.
ExcaliClaw’s hosted Streamable HTTP MCP (https://excaliclaw.com/mcp) lets Claude Code/Desktop, Cursor, Codex, VS Code, OpenCode and OpenClaw list/create/update diagrams, ER/flowcharts, collections, PNG/SVG export, and live canvas collab under browser OAuth—unlimited MCP on all plans; launched on Product Hunt around Oct 12, 2026.
