 All three companies in the article converge on **Slack as the primary invocation surface**. Open SWE does the same:
 
 - **Slack** — Mention the bot in any thread. Supports `repo:owner/name` syntax to specify which repo to work on. The agent replies in-thread with status updates and PR links.
-- **Linear** — Comment `@openswe` on any issue. The agent reads the full issue context and posts results back as comments.
+- **Linear** — Comment `@openswe` on any issue. The agent reacts with 👀 to acknowledge, reads the full issue context, and posts results back as comments.
 - **GitHub** — Tag `@openswe` in PR comments on agent-created PRs to have it address review feedback and push fixes to the same branch.
 
 Each invocation creates a deterministic thread ID, so follow-up messages on the same issue or thread route to the same running agent.
