+
+After Claude publishes a page from a channel or a thread, it keeps watching that page for comments. Open the page, start a comment on the part you want changed, and send the comment with **Send to Claude** or mention `@claude` in it. The comment reaches the Claude session behind the Slack thread that published the page, even if that thread has been quiet for a while. Claude answers in the comment thread on the page, in the Slack thread, or both, and when the comment asks for a change, it edits the page and publishes the update to the same link, so everyone with the page open sees it.

+
+Comments reach Claude on pages it published from a channel or from a thread in a channel. For a page Claude published in a direct message, or an artifact you published from your own Claude Code session and linked in Slack, ask for changes in the conversation where the page was made. If a comment you sent goes unanswered, ask in the Slack thread. A message there reaches Claude whether or not it is still watching the page, and Claude can pick the page back up from the link it posted.

 ### Keep a capture channel
 
 Planning inputs arrive over a month, not in one sitting. Forward messages and ideas to one channel as you find them, then ask for a synthesis when you need the artifact.

 ## Establish key criteria

 * **Capabilities:** What specific features or capabilities will you need the model to have to meet your needs?
 * **Speed:** How quickly does the model need to respond in your application? Claude Opus 5 and Claude Opus 4.8 support [fast mode](https://platform.claude.com/docs/en/build-with-claude/fast-mode) (research preview), which delivers up to 2.5x higher output speed at premium pricing.
 * **Cost:** What's your budget for both development and production usage?
-* **Effort:** Recent Opus and Sonnet models support an [effort parameter](https://platform.claude.com/docs/en/build-with-claude/effort) that trades intelligence for latency and cost within a single model. Tuning effort is often a better lever than switching models. On Claude Opus 5, start with the default (`high`) and adjust up or down based on your evals. On Claude Opus 4.8 and Claude Opus 4.7, the `xhigh` effort level, between `high` and `max`, is the best setting for most coding and agentic use cases.
