Hane Cowork
Work on this PC
How work started from New work runs in the bundled harness, which local tools it can use, the work folder, reading progress, stopping, and on-device history.
This page explains how a request sent from 「新しい作業」 (New work) runs on your PC, which tools it can use, how to read progress and stop work, and how history is kept.
Recorded in the actual Hane Cowork app (connected to a test Platform with scripted model responses). The app UI is in Japanese; English captions explain each step.
How a request runs
Section titled “How a request runs”A request sent from 「新しい作業」 (New work) becomes 「この PC での作業」 (work on this PC). For each request, Cowork does the following:
- Reads the organization policy from Platform and starts a Cowork model session.
- Starts the bundled harness and passes it the request text.
- The harness plans the steps, calls the model as needed, and uses local tools.
- Each time a tool is used, Cowork checks the organization policy. For actions that need confirmation, it waits for your decision on screen.
- When the reply arrives and the work ends, Cowork shows 「応答が完了しました」 (Reply complete). Whether the work completes, is stopped, or fails, Cowork revokes the model session at that point.
The harness is a fixed version bundled with Cowork. Cowork never uses other tools installed on your PC. The model is one that your organization has allowed for Cowork. There is no screen for choosing a model.
When you send another request in the same work, the harness keeps the context of the earlier requests. If the connected Platform, organization, or model changes, Cowork starts fresh without carrying the old context over.
Available tools
Section titled “Available tools”Cowork gives the harness the tools below. Tools for capabilities that the organization denies are not even listed to the harness.
| Organization policy capability | Tools | Scope |
|---|---|---|
| 「作業フォルダのファイル」 (Work-folder files) | List the work folder, read a file, save a file | UTF-8 text inside the chosen work folder |
| 「Chrome の操作」 (Chrome actions) Preview | Check shared tabs, read a page, click, type, scroll | Only Chrome tabs you shared (Use your everyday Chrome) |
| 「PC の操作」 (Computer use) Preview | Capture the chosen app’s screen, operate the chosen app | Only the window you chose (Operate apps) |
Typing into a page can also send local content outward, so it follows both the Chrome actions rule and the external transfer rule.
Work folder
Section titled “Work folder”You choose a work folder for each task. Press the folder button below the request box (「作業フォルダを選ぶ」, Choose work folder), and the chosen folder’s name appears below the box. Press 「作業フォルダを外す」 (Remove work folder) next to it to remove it.
- A folder chosen for new work becomes that task’s work folder when you send the first request. It is not carried over to the next new task, so choose one for each task.
- Follow-up requests in the same task use the same folder. You can choose again or remove it from the request box only while the work is not running.
- The tools accept only paths inside the work folder. Links must also resolve to a location inside the folder.
- Only UTF-8 text files of up to 1 MB can be read.
- Even with a work folder selected, whether files can be read or written depends on the organization policy.
- If the chosen folder was moved or deleted, Cowork does not start the work and shows 「作業フォルダが見つかりません。フォルダを選び直してから、もう一度依頼してください。」 (The work folder was not found. Choose the folder again and resend the request).
For work you keep coming back to in the same folder, use a work group so you don’t have to choose the folder every time.
If the agent tries to save outside the work folder, Cowork does not do it and records the reason in progress: 「作業フォルダの外、または選んでいないフォルダは使えません。」 (Cannot use a location outside the work folder or a folder you did not choose).
Reading progress
Section titled “Reading progress”「作業の進行」 (Progress) under the request lists the tools the harness used, in order. Each action has a status such as:
| Status | Meaning |
|---|---|
| 「作業しています」 (Working) | The action is running |
| 「確認を待っています」 (Waiting for confirmation) | Waiting for your decision |
| 「実行しませんでした」 (Not run) | Stopped by the organization policy or your decision. The reason is shown |
| 「進行の確認が必要です」 (Progress needs checking) | The result could not be confirmed because of a stop or disconnection |
Progress for earlier requests is collapsed and can be reopened from 「この依頼の進行」 (Progress for this request). Actions whose completion could not be confirmed are never shown as successful.
While work is running, you can write a draft of your next request in the request box. You can send it after the current work ends.
Stopping work
Section titled “Stopping work”While work runs, the send button changes to 「作業を止める」 (Stop work). Pressing it:
- Terminates the harness together with the processes it started.
- Revokes the Platform model session so that further model calls are rejected.
- Never reports unfinished work as complete.
If you quit or restart the app, work that was running is not resumed; it returns to a stopped state.
Results and history
Section titled “Results and history”Files saved by the harness appear in your work folder. You can copy reply text, and export conversations as Markdown.
Press the pen button next to a work item in the sidebar to open 「会話を管理」 (Manage conversation), where you can:
- Rename, pin, or archive the conversation
- 「会話を Markdown に書き出す」 (Export the conversation as Markdown)
- 「この端末の履歴を削除」 (Delete from this device’s history)
Conversations and harness records are saved in the app data on this device and are not synced between devices. Deleting a conversation also deletes its harness records. For what is stored, see How Cowork keeps things safe.
