yoni-at-strixandGitHub 8551339130 feat: place caller-provided files into the sandbox workspace (extra_files, --workspace-file) (#1085)
* add extra-files plumbing so orchestrators can drop single files into the sandbox workspace

* reject extra-file paths that collide with a local source tree

* add --workspace-file so CLI users can place files in the sandbox workspace

* reject repeated and control-character workspace paths

* revalidate persisted workspace files when resuming a run

* drop the workspace-file size limit

<Tip>
Be specific. Good instructions help Strix prioritize the most valuable attack paths.
</Tip>
## Workspace files
Instructions become part of the prompt. To give Strix a file to work with, such
as a wordlist, an API specification, or notes, use `--workspace-file`. Strix
places the file into the sandbox workspace before the scan starts.
```bash
strix --target https://app.com --workspace-file ./wordlist.txt
```
The file lands at `/workspace/<file name>`. To choose the destination, write
`PATH:DEST`. `DEST` is a path inside `/workspace`.
```bash
strix --target https://app.com \
--workspace-file ./openapi.yaml:specs/openapi.yaml \
--workspace-file ./notes.md
```
Repeat the option for every file you want to place. Strix lists the files in the
agent task, so the agent knows where to read them.
Rules that apply to every workspace file:
- The file is read-only inside the sandbox.
- The destination must stay inside `/workspace`.
- The destination must not fall inside a target directory, because target files
come from the target itself. Strix skips such a file and logs a warning.
- Two files cannot claim the same destination.
<Note>
A workspace file is data for the agent to use. It is not a scan target, and its
contents do not change the instructions.
</Note>
<Warning>
Do not place secrets in a workspace file. The sandbox runs untrusted target
code, so treat anything you place there as readable by the target.
</Warning>
