src/content/docs/agents/tools/workspace.mdx:92,212,432—WranglerConfigrequires TOML input (JSON is auto-generated). Also use$todayforcompatibility_date. - HIGH
src/content/docs/agents/tools/workspace.mdx:367— Baretscode block for a type interface; useTypeScriptExample. - MEDIUM
src/content/docs/agents/tools/workspace.mdx:15,76,129— Run-on sentences and typo. - MEDIUM

Add PackageManagers to imports for install commands:

| Most work performed by an agent that requires a filesystem doesn't require a heavy Linux environment. Workspaces live inside a [Durable Object](/durable-objects/) right next to your agent harness. | ||

| Take advantage of the speed of working on files within the Worker environment and should a Linux environment be needed, you can drop into a [Cloudflare Container](/containers/) to execute bash commands, changes in either environment are reflected everywhere. |

Remove await from constructor — constructors cannot be async:

| const report = await this.#workspace.fs.readFile("/workspace/data/report.csv", "utf8"); | |
| } | |

| 1. A Durable Object constructs a `Workspace` backed by the Durable Object SQLite storage and configures a backend (currently a Cloudflare Container). | ||
| 2. The backend starts the container, whose entrypoint is the a small `wsd` client. `wsd` mounts the workspace at a path inside the container using FUSE. |

| ## Shell API | ||
|
|
||
| `ws.shell.exec(command, options?)` spawns a command inside the container and returns an `ExecHandle` stub. Today's API is run-and-wait — call `handle.result()` to await the exit code and collected output. Streaming exec is coming soon. |
