5252The footer under each reply names the model that handled it. You can [choose a different model](/docs/claude-tag/users/models) yourself, and admins [set the default model for each channel](/docs/claude-tag/admins/customize#choose-the-model-for-a-scope). In a channel, the footer also has a **Configure** link; open it to [tailor how Claude works in this channel](/docs/claude-tag/users/good-habits#configure-claude-for-a-channel). Replies in DMs and in org-shared channels have no Configure link.

6060## Hand Claude a task

8080After you've handed Claude a task, the first question is what it has to work with. The short version: it reads the thread you tagged it in, it can search your workspace's public channels, and anything beyond Slack depends on what your admin connected.

82| What you give Claude | Can Claude read it? |
83| :---------------------------------------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
84| Messages in this thread | Yes. Mentioning it mid-thread also gives it the thread's earlier messages |
85| A file you attach (image, screenshot, PDF, or another type) | Yes, up to a size limit that depends on the file type. See [Files you attach](#files-you-attach) |
86| Other public channels in your workspace | By searching only, the same way a person searches Slack; Claude can find a message by keyword but can't read a channel's full history unless it's been added there |
87| Private channels and DMs | Only from inside them. Adding Claude to a private channel lets it work there, but the channel stays unreadable from any other channel or DM. |
88| A link you paste, like a Google Doc or a webpage | If your admin allowed that site for this channel, or, for a file behind your own login, if you've [allowed Claude to use your connectors](/docs/claude-tag/concepts/personal-connectors). If neither applies, Claude tells you it can't reach it. |
89| A Slack canvas | No |
90| A message you edited after sending | Yes. Each edit sends Claude a note showing the text before and after the edit. An edit never starts a new task on its own, so to be sure a correction is picked up, say it in a new reply; see [Reply in the thread to steer](/docs/claude-tag/concepts/how-it-works#reply-in-the-thread-to-steer) |

9292The fastest way to find out for your channel is to ask: `@Claude can you read the doc I just linked?` gets you a yes or a "that site isn't allowed here."
