## Problem The `local` sandbox uses the run's `source_directory` (the CLI's cwd at invocation time) as its working directory and `create_dir_all`s it on the server (`LocalSandbox::initialize` in `fabro-sandbox`). That is correct when the CLI and the server share a host — the agent operates directly on the user's project tree. When the server is **remote** from the CLI — e.g. `fabro serve` running in a container in Kubernetes, driven over HTTP with the `local` sandbox — the client's cwd (e.g. `/Users/alice/project`) does not exist on the server. The sandbox then tries to create that path as the (often unprivileged) server user and fails at init: ``` sandbox.failed provider="local" error="Failed to create working directory" causes=["Permission denied (os error 13)"] ``` and the run dies with `workflow_error` before the agent starts. ## Fix When `source_directory` is absent or does not exist on the server, fall back to a server-writable `workspace` directory under the run's scratch dir instead of recreating the client path. **Same-host behavior is unchanged**: an existing `source_directory` is still used as-is. The selection is extracted into a small pure helper, `local_working_directory(source_directory, run_dir)`, so it can be unit-tested directly. ## Testing - `cargo test -p fabro-workflow local_working_directory` — 3 new tests (existing source dir → used; absent → fallback; present-but-missing-on-server → fallback) - `cargo check -p fabro-workflow` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Thanks for fabro @brynary! --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |
