122122### Instruction layers
123123
124Three kinds of standing instruction can apply in a channel, written by different people:
124The table lists the kinds of standing instruction that can apply in a channel and who writes each.

126| Layer | Who writes it | Where |
127| :------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------- |
128| Custom instructions | Owner for any scope; channel members and [channel managers](/docs/claude-tag/admins/restrict-access#delegate-channel-setup-to-channel-managers) for the channel scope, unless members are [restricted](#restrict-who-can-set-channel-instructions) | The scope's panel in admin settings, or the **Configure** link in any reply footer for the channel scope |
129| Channel memory | Anyone in the channel | By telling Claude to remember |
130| Task prompt | The requester | The message itself |

132133Channel members can shape how Claude responds in their channel through memory, but they can't change which credentials or repositories it has; that's bundle configuration. See [who controls what](/docs/claude-tag/admins/customize) for the full split.

142143The field is plain text, inserted as written; there is no include or template syntax, and `{{include:...}}` is passed through literally. To give Claude a repository's `CLAUDE.md`, [grant the repository](/docs/claude-tag/admins/configure-github#grant-repository-access) and name it in the request; its `CLAUDE.md` loads after the clone completes.

144What Claude reads in a channel is the concatenated custom instructions of its scope chain, plus the `CLAUDE.md` of any repository it clones. Projects in claude.ai don't apply here; Claude doesn't read a Project's instructions or knowledge in Slack, and a channel can't be pointed at a Project.
145What Claude reads in a channel is the concatenated custom instructions of its scope chain, the channel's [managed instructions](/docs/claude-tag/admins/managed-by#how-managed-instructions-load) if another channel manages it, and the `CLAUDE.md` of any repository it clones. Projects in claude.ai don't apply here; Claude doesn't read a Project's instructions or knowledge in Slack, and a channel can't be pointed at a Project.

146147A new instruction applies to sessions started after you save it. Claude reads it in every new thread right away, keeps the old text in a thread that's already running, and picks it up at the channel's top level on the next channel message, when it replaces the channel's session (see [Attach the bundle](#attach-the-bundle)). Claude doesn't read a channel's instructions in another channel or in a DM. To confirm what a session is reading, start a new thread and ask Claude to repeat its admin instructions.
