This issue was created from Discord post 1473270947413885040:

Workspace options like skills, instructions, model, tools, and memory all support dynamic functions that receive requestContext:

skills: (context) => { ... }          // :white_check_mark: dynamic

But filesystem only accepts a static instance:

// no way to resolve dynamically per request
filesystem: new LocalFilesystem({
    basePath: './workspace',
    readOnly: false,
})

Use case: We run a multi-role agent on a shared workspace. Each role should be scoped to a different filesystem root or have different read/write permissions. Today we're forced to create separate Workspace instances per role at the run time.

Requested: Allow filesystem to accept a function that receives requestContext, matching the pattern of every other dynamic option:

const workspace = new Workspace({
    filesystem: ({ requestContext }) => {
      const role = requestContext.get('agent-role');
      return new LocalFilesystem({
        basePath: `/workspaces/${role}`,
      });
    },
    // ...
});

This would let a single Workspace instance dynamically scope filesystem access per request different base paths, different permissions, or even different filesystem implementations (local vs S3).
