Restores the legacy persistent-IPython tool's *ergonomics* (proxy helpers pre-bound, structured stdout/stderr/error returns) without the in-container daemon: each call ships ``strix.tools.proxy._calls`` source into ``/tmp`` alongside a per-call driver, runs ``python3 -u`` against it, and parses a sentinel-delimited JSON payload back from stdout. The driver fetches its own guest token from Caido at ``localhost:48080`` and binds ``list_requests`` / ``view_request`` / ``send_request`` / ``repeat_request`` / ``scope_rules`` to that client; user code runs inside an ``async def`` wrapper so top-level ``await`` works. The proxy SDK call sequences live in one file — ``strix/tools/proxy/_calls.py`` — and are reused by both the host-side ``@function_tool`` wrappers (which add JSON serialization for the LLM) and the in-container kernel (which exposes the bare async functions). No code duplication; the helper logic itself is host-shipped, so tweaking the proxy helpers does not require an image rebuild. Image: a single ``pip install caido-sdk-client`` line so the driver's ``import caido_sdk_client`` resolves. Skill ``tooling/python`` is always-loaded alongside ``tooling/agent_browser``. Trade-off accepted: state does not persist across calls (no kernel). For multi-step workflows the agent combines into one ``code`` block or writes a script to ``/workspace/scratch/`` and runs via ``exec_command``. If a workflow surfaces that genuinely needs persistence, the same tool surface migrates to a kernel-backed executor without changing the LLM contract.

"""Caido proxy tools — host-side ``@function_tool`` wrappers around ``_calls``.
|
|
|
|
The five tools delegate to :mod:`strix.tools.proxy._calls` for the actual
|
|
caido-sdk-client work and add LLM-friendly JSON serialization + error
|
|
wrapping on top. The shared call layer is also reused by the
|
|
``python_action`` tool to expose the same proxy surface inside the
|
|
sandbox's Python kernel — single source of truth for the SDK shapes.
|
|
|

Tools: ``list_requests``, ``view_request``, ``send_request``,
|

``repeat_request``, ``scope_rules``.

``req.port.eq:443``.
|
|
- **Text/byte fields** (``req.method``, ``req.host``, ``req.path``,
|
|
``req.query``, ``req.ext``, ``req.raw``) — ``regex``, ``cont``
|
|
(substring), ``eq``. Examples: ``req.method.eq:"POST"``,
|
|
``req.path.cont:"/api/"``, ``req.host.regex:".*\\.example\\.com"``.
|

- **Date fields** (``req.created_at``) — ``gt``, ``lt`` with ISO
|
|
timestamps: ``req.created_at.gt:"2024-01-01T00:00:00Z"``.
|
|
- **Combine** with ``AND`` / ``OR``: ``req.method.eq:"POST" AND

resp.code.gte:400``.
|
|
- **Special**: ``source:intercept`` (only intercepted requests),
|

``preset:"name"``.
