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

LLMs have broad but shallow security knowledge. They know _about_ SQL injection but lack the nuanced techniques that experienced pentesters use, such as parser quirks, bypass methods, validation tricks, and chain attacks.

Both use the same engine and produce the same validated findings and SARIF, so agents can pick per situation or combine them:
- **Open-source CLI (self-hosted):** Runs locally in a Docker sandbox with your own LLM key. It is free, fully local, and air-gap capable. It suits local development loops and full control.
- **Managed cloud:** Runs on Strix infrastructure through the [app.strix.ai REST API](https://docs.app.strix.ai). It needs no Docker, LLM key, or local installation. The Enterprise plan adds team dashboards, scheduling, pull request reviews, and downloadable PDF or DOCX reports. It suits sandboxed or CI environments and teams.

## Agent-Friendly Interfaces
Everything an agent needs is machine-readable:
- **Headless CLI:** `strix -n` runs without the TUI. It exits with `0` for a clean scan, `1` for an error, or `2` for vulnerabilities.
- **REST API:** The managed platform exposes a documented [OpenAPI](https://docs.app.strix.ai/openapi.json) at `https://app.strix.ai/api/v1`. It supports scans, vulnerabilities, assets, pull request reviews, schedules, and webhooks. The API uses bearer tokens and scopes.
- **Structured results:** Each self-hosted run writes `vulnerabilities.json`, `vulnerabilities.csv`, and `findings.sarif` in SARIF 2.1.0 format. It also writes per-finding Markdown under `strix_runs/<run-name>/`. The cloud exposes the same data as JSON and provides SARIF export.
- **Budget controls:** `--max-budget` and `--max-turns` set cost and turn limits.
- **`AGENTS.md`:** The [repository's agent guide](https://github.com/usestrix/strix/blob/main/AGENTS.md) provides a quick reference.
- **`llms.txt`:** The index is available at [docs.strix.ai/llms.txt](https://docs.strix.ai/llms.txt). The full export is available at [docs.strix.ai/llms-full.txt](https://docs.strix.ai/llms-full.txt). Every page is also available as Markdown by appending `.md` to its URL.
- **Headless CLI** `strix -n` runs without the TUI and exits with `0` (clean), `1` (error), or `2` (vulnerabilities found).
- **REST API** — the managed platform exposes a documented [OpenAPI](https://docs.app.strix.ai/openapi.json) at `https://app.strix.ai/api/v1` (scans, vulnerabilities, assets, PR reviews, schedules, webhooks) with bearer tokens and scopes.
- **Structured results** — every run writes `vulnerabilities.json`, `vulnerabilities.csv`, `findings.sarif` (SARIF 2.1.0), and per-finding Markdown under `strix_runs/<run-name>/`; the cloud exposes the same as JSON plus SARIF export.
- **Budget controls** `--max-budget` and `--max-turns` give agents hard cost/time caps.
- **`AGENTS.md`** — the [repository's agent guide](https://github.com/usestrix/strix/blob/main/AGENTS.md) with a quick reference.
- **`llms.txt`** — this documentation is indexed at [docs.strix.ai/llms.txt](https://docs.strix.ai/llms.txt) and fully exported at [docs.strix.ai/llms-full.txt](https://docs.strix.ai/llms-full.txt); every page is also available as Markdown by appending `.md` to its URL.

### Fixes by server
**llama.cpp (`llama-server`)**
- Run with `--jinja` and a correct tool-use chat template (`--chat-template` or `--chat-template-file` matching the model). Recent builds enable `--jinja` by default. Upgrade if yours does not.
- For thinking models, align or disable reasoning (`--reasoning-format` or `-rea off`) so it does not break tool-call parsing.
- A low temperature, such as `--temp 0.2`, improves tool-call reliability.

- For thinking models, align or disable reasoning (`--reasoning-format`, `-rea off`) so it doesn't break tool-call parsing.
- A low temperature (e.g. `--temp 0.2`) improves tool-call reliability.
**Ollama**
- Use a recent Ollama and a model whose template wires tools. Modern Ollama returns `tools param requires --jinja flag` if the template lacks tool support.
- For reasoning models such as qwen3, disable the model's **thinking** mode. Thinking left on can push the tool call into `content` instead of the structured `tool_calls` field. Turn it off on the Ollama side with a non-thinking model variant, `think: false` in the model's parameters, or `Modelfile`.
- Raise **`num_ctx`** to at least 16k to 32k. Strix sends a large system prompt plus many tool schemas. At Ollama's small default context, the tool definitions can be truncated from the prompt. The model can then stop emitting valid calls. A short test prompt can look fine while a real scan fails. Set this explicitly instead of inferring it from a quick check.

Strix exposes the Caido proxy to your host machine, so you can interact with it alongside the automated scan. When the sandbox starts, the Caido URL is displayed in the TUI sidebar — click it to copy, then open it in Caido Desktop.
### Accessing Caido
1. Start a scan as usual
2. Find the **Caido** URL in the sidebar stats panel, such as `localhost:52341`

4. Click **Continue as guest** to access the instance
### What You Can Do
- **Inspect traffic:** Browse all HTTP/HTTPS requests the agent is making in real time
- **Replay requests:** Take any captured request and resend it with your own modifications
- **Intercept and modify:** Pause requests mid-flight, edit them, then forward
- **Explore the sitemap:** See the full attack surface the agent has discovered
- **Manual testing:** Use Caido's tools to test findings the agent reports, or explore areas it has not reached

<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.

Each ``extra_files`` entry (``{"workspace_path": "/workspace/<rel>",
"content": bytes | str}``) lands as a single file at its ``workspace_path``
regardless of backend: an in-memory ``File`` manifest entry on manifest
backends, a read-only bind mount of a host-staged copy on bind-mount
backends.
