Working with files
Ask Tag to review attachments and save and update files in your workspace.
Your workspace is the folder where Tag works on your files. Upload a brief in Slack and ask Tag to save the open questions there. As you answer them, ask Tag to update the saved file.
This guide works with Codex or Claude Code and assumes you have completed
your first Tag task. Claude uses the same
workspace with .claude/skills and .mcp.json.
Turn a brief into questions you can resolve
Before a launch meeting, attach your existing brief as a text or Markdown file to a Slack message mentioning Tag. Ask it to flag anything you need to settle before launch, then answer its questions in the same thread.
Tag has updated open-questions.md. One decision remains: who makes the final
call to launch?
Click ↗️ open-questions.md to open the saved file, or 📁 Open folder to browse
its folder. Both open on the computer running Tag. If someone else hosts Tag,
they open on that person's computer.
Uploading the brief lets Tag read it for the request. It does not automatically
save a copy of the brief in the workspace. In this example, you asked Tag to save
open-questions.md. New saved artifacts go in artifacts/CHANNEL_ID/ inside
your Tag folder, so files from different Slack channels stay separate. Channel
IDs keep these folders stable when channels are renamed. An explicit output
path is respected, and edits to existing files stay in place. Older files remain
where they were saved; Tag does not guess which channel owns them.
Files and indexing
Files saved in the workspace are not automatically indexed. However, Tag can still locate and read them using a filename you mention or one already in the conversation. See What Tag knows for how indexed search works.
Also attach saved files in Slack
By default, Tag keeps each requested deliverable locally and uploads a copy to the requesting Slack thread. The reply keeps one 📁 Open folder button for access to the local copies. Successful uploads omit individual Open file buttons; local-only files and files that could not upload keep those file buttons.
To keep saved deliverables local-only, configure your Tag:
tag config set OPENTAG_FILE_DELIVERY local
tag restartUse local+slack to restore the default. Existing installations automatically
adopt this default during startup if no delivery preference is saved. An explicit
local setting is preserved. This applies to requested final file deliverables,
not supporting files or every file in the workspace. Generated images retain
their existing delivery behavior.
An individual request can override the default: ask for an attachment to upload a copy, or explicitly ask to keep the file local to prevent an upload.
Slack attachments are copies, not synchronized files. Later edits to the local file do not update an earlier attachment. Files above Tag's 15 MiB upload limit remain available through their local Open button. If Slack delivery fails, Tag keeps the local file, reports the failure, and continues with other files. Ask Tag to attach it again after resolving the failure, or to create a smaller copy for an oversized file.
Use earlier files in a thread
Tag automatically opens the files on your current message. If your message has none, it opens the most recent message with files. When a request depends on other files earlier in the thread, such as "what do you think about both?", Tag opens those files too, up to 15 MB each. It can open only files shared in the current channel. If it cannot open a file, it says so instead of commenting on it. An earlier file over 15 MB is skipped rather than blocking the request, so you can give Tag a local path or link to it instead.
Images Tag returns in a thread are also kept in the channel's images folder
under artifacts/ in the workspace, so Tag can reopen its own earlier results.
Use a forwarded Slack file
Tag can read supported files attached to forwarded Slack messages, as well as files you upload directly. Forward the message containing the file into a conversation where you use Tag, then mention Tag in that thread and explain what you want it to do with the file.
The file must be accessible to Tag through Slack. If Tag cannot retrieve it, attach a copy you intend to share directly in the task thread. Forwarding a message does not give Tag access to the rest of the original conversation.
Forwarded files use the same attachment limits as direct uploads: downloaded files are limited to 15 MiB each, and text included in the request is truncated at 12,000 characters per item. Reading images and other file formats also depends on the backend's available tools. Tag reads bounded thread context, so keep the file and request together in a short thread.
Like a direct upload, forwarding a file does not automatically save it in your workspace. Ask Tag to save a copy if you want to keep working on it later.
Find your workspace
The workspace lives on the computer running Tag. If someone else hosts Tag for your team, the folder is on their machine. In the Tag app, open the Tag, choose Details, and click Show next to Working folder. From a terminal, run:
tag pathsFind the workspace path in the output. A normal installation names each Tag's
folder after its Slack workspace and app IDs, in lowercase, such as
~/Tag/t0abc123-a0xyz789. Tags created by earlier releases in ~/Tag/default
or ~/Tag/NAME are moved there automatically once their Slack app is known.
Custom installations can use a different location, so use the path Tag reports.
Tag keeps this folder separate from its application releases. Files and local
skills stay in place when you upgrade. Its hidden .tag directory holds this
Tag’s settings, credentials, integrations, and conversation state. Keep that
directory with the working files when moving the folder. You can organize it like any working
folder:
workspace/
artifacts/
C0123456789/
open-questions.md
meeting-notes/
templates/
weekly-report.mdThe workspace is the agent's starting directory. Its actual file and command access depends on the backend's permissions; the folder itself is not a sandbox. See the security policy for the execution model.
Keep working on the result
Files Tag saves are ordinary files. Open the checklist in your editor, make changes yourself, or use it in another tool. On a later request, tell Tag which file to read so it can work from the current version. Your work stays in your working folder when Tag is upgraded.
