* fix(proxy,tooling): serialize+reconnect Caido client, actionable HTTPQL errors, sandbox tool guidance
Addresses the top recurring agent tool-call failures observed in telemetry:
- proxy: the shared Caido client had no locking or reconnect, so concurrent
agent calls raced ("Transport is already connected") and a dead transport
poisoned the rest of the run ("Connector is closed"/"Server disconnected").
Add an asyncio lock + bounded reconnect in caido_api.call_with_client (sandbox
path) and a scan-wide caido_lock in the run context that host-side proxy tools
hold around every call. Deterministic errors are not retried.
- proxy: list_requests now returns Caido's exact parser message, echoes the
offending query, and includes a corrected-syntax hint so agents self-correct
instead of retrying a broken HTTPQL filter.
- shell/prompt: document that write_stdin requires a process started with
tty=true; nudge toward writing Python to a file over deeply-nested one-liners;
note the venv pre-installs common libs.
- agent-browser: distinguish daemon/connection failures (run doctor, don't loop)
from malformed commands; invoke directly (no sh -c wrapper).
- containers: use POSIX '.' instead of the bashism 'source' in generated rc
files (fixes 'sh: source: not found'); add file + xxd and pre-install
requests/httpx/beautifulsoup4/lxml/pyjwt/cryptography in the sandbox venv.
- tests: cover proxy serialization/reconnect/no-retry and HTTPQL errors.
* fix(proxy): host-side reconnect, close stale clients, don't retry mutations
Addresses Greptile review on the reconnect logic:
- Host path had no reconnect: a dead shared context client (Caido restart /
network blip) previously disabled proxy tools for the rest of the scan. Add
SharedCaidoClient, a serialized reconnect-safe holder stored once per scan in
the run context and shared across agents. On a dead transport it rebuilds via
reconnect_caido, which re-selects the SAME Caido project (preserving captured
traffic) instead of creating a new empty one.
- Don't repeat completed mutations: call_with_client / SharedCaidoClient.call
take idempotent=. Reads retry once on reconnect; replay + scope
create/update/delete heal the client but re-raise instead of risking a
double-apply.
- Don't leak replaced clients: the stale client is aclose()d (best-effort) on
every reconnect.
- Extend tests to cover close-on-reconnect, non-idempotent re-raise, and the
SharedCaidoClient holder.
* fix(proxy): close replacement Caido client when project.select fails
Addresses Greptile P1: in reconnect_caido (and bootstrap_caido) a successful
connect() followed by a failing project.select()/create() discarded the
connected client without closing it, so a missing/unavailable project could
leak a transport on every retry. Close the client before re-raising.

AGENT_BROWSER_ARGS parser splits on commas, so any flag value
containing one (--disable-features=A,B, --window-size=1920,1080,
--lang=en-US,en) shredded into garbage positionals and Chromium
rejected the launch with "Multiple targets are not supported in
headless mode". Reduce to a comma-separated list of comma-free
flags that keeps the AutomationControlled anti-detection bit.
Default screenshot path now resolves inside the workspace root so
view_image accepts it; entrypoint pre-creates the dir at runtime
(the build-time mkdir is shadowed by the /workspace mount). Skill
examples updated to favor the no-arg form, plus brief fallback
guidance when view_image is unavailable on text-only models and a
viewport-resize note for sites that gate on real desktop dims.
Also drop the stale STRIX_DISABLE_BROWSER doc entry — no code
reference exists.
Combined commits 2+3 of the migration plan because the FastAPI sidecar
removal in commit 2 broke ``browser_action`` (which lived in the
sidecar); they have to land together.
Sandbox tool layer (commit 2 piece):
- ``build_strix_agent`` now returns a ``SandboxAgent`` with
``capabilities=[Filesystem(), Shell()]``. The SDK runtime binds the
capabilities to the live sandbox session per-run; agents get
``exec_command``, ``write_stdin``, ``apply_patch``, ``view_image``
function tools auto-merged into their tool list. Plain ``Agent``
short-circuits capability binding (``agents/sandbox/runtime.py:190``).
- Drop ``Compaction`` from the default capability set — it's
OpenAI-Responses-API-only and useless for our litellm-routed
Anthropic setup.
- Delete the entire custom in-container tool layer:
- ``strix/tools/terminal/`` (5 files, 748 LoC libtmux)
- ``strix/tools/file_edit/`` (3 files, 276 LoC)
- ``strix/tools/python/`` (5 files, 459 LoC)
- ``strix/runtime/tool_server.py`` (163 LoC FastAPI sidecar)
- ``strix/tools/_sandbox_dispatch.py`` (117 LoC)
- ``strix/tools/registry.py`` (109 LoC)
- ``strix/tools/context.py`` (12 LoC)
- Drop the corresponding TUI renderers (``terminal_renderer.py``,
``file_edit_renderer.py``, ``python_renderer.py``) and update
``interface/tool_components/__init__.py``.
Browser → agent-browser CLI (commit 3 piece):
- Install ``agent-browser@0.26.0`` globally in the Dockerfile right
after the existing ``npm install -g`` block. Run
``agent-browser install --with-deps`` (apt, root) and
``agent-browser install`` (Chrome download, pentester) +
``agent-browser doctor --offline --quick`` smoke test.
- Drop the explicit Playwright system-deps apt list (replaced by
``--with-deps``) and ``RUN .venv/bin/python -m playwright install
chromium``.
- Vendor ``agent-browser/skill-data/core/SKILL.md`` →
``strix/skills/tooling/agent_browser.md`` (476 lines). Adapt
frontmatter to Strix format; strip the install/Quickstart and the
``agent-browser skills get electron|slack|...`` specialized-skills
block; add the "Caido proxy is wired via env vars; do not pass
``--proxy``" note.
- ``_resolve_skills`` now eagerly loads ``tooling/agent_browser`` for
every agent (matches the previous unconditional ``browser_action``
in ``_BASE_TOOLS``).
- Delete ``strix/tools/browser/`` (5 files, 1338 LoC) and the
``browser_renderer.py`` TUI render.
Sandbox plumbing:
- Drop ``bearer`` token, ``tool_server_host_port`` resolution + bundle
keys, ``TOOL_SERVER_TOKEN``/``TOOL_SERVER_PORT``/
``STRIX_SANDBOX_EXECUTION_TIMEOUT`` from the manifest env in
``session_manager.create_or_reuse``. Caido proxy env vars
(``http_proxy``, ``https_proxy``, ``ALL_PROXY``) stay; manifest
applies them to every ``docker exec``-spawned process.
- Drop ``sandbox_token`` and ``tool_server_host_port`` params from
``make_agent_context`` and the ``create_agent`` graph tool.
- Drop the tool-server health-check from ``entry.py`` (only Caido's
``wait_for_tcp_ready`` remains).
- ``docker-entrypoint.sh``: delete the ~30 line
``Starting tool server...`` block (sudo + uvicorn launch + curl
/health poll). Add ``NO_PROXY=localhost,127.0.0.1`` to
``/etc/profile.d/proxy.sh`` and ``/etc/environment`` so the
agent-browser daemon's CDP traffic on localhost isn't routed
through Caido.
pyproject.toml:
- ``[project.optional-dependencies] sandbox = []`` (every member of
the previous list — fastapi, uvicorn, ipython, openhands-aci,
playwright, libtmux — is gone with the sidecar).
- Drop ``numpydoc.*``, ``IPython.*``, ``openhands_aci.*``,
``playwright.*``, ``uvicorn.*``, ``pyte.*``, ``libtmux.*`` from
the missing-imports module list.
- Drop the per-file ruff ignores for the deleted modules.
Net delta: −5512 LoC. ruff drops to 3 errors (was 21 baseline). mypy
falls to 69 errors over 3 files (was 84 over 8 — the drop comes from
deleting the modules with the worst untyped-import problems).

Drop our 797-LoC manual GraphQL ``ProxyManager`` and the in-container
sandbox dispatch. Caido goes host-side via the official async Python
SDK. The Caido CLI still runs as a sidecar in the container — only the
control-plane moves.
Bootstrap moves host-side:
- New ``strix/sandbox/caido_bootstrap.py``: ``loginAsGuest`` via
aiohttp (5 retries), then ``client.project.create(temporary=True)``
+ ``client.project.select(...)``, then return the connected
``caido_sdk_client.Client``. Drop the equivalent bash from
``docker-entrypoint.sh`` (~60 lines of curl + jq).
- ``entry.py`` calls ``bootstrap_caido_client`` after the
``wait_for_tcp_ready`` healthcheck, stashes the client in the bundle
and threads it through ``make_agent_context(caido_client=...)``.
``agents_graph.create_agent`` propagates the same client to children.
- ``session_manager.cleanup`` ``await``s ``client.aclose()`` before
tearing down the container.
- Drop ``CAIDO_PORT`` from the manifest env (only the in-container
ProxyManager read it) and ``CAIDO_API_TOKEN`` from the entrypoint's
``/etc/profile.d/proxy.sh`` + ``/etc/environment`` heredocs.
Tools (``strix/tools/proxy/tools.py``):
- ``list_requests`` → ``client.request.list().filter().first().after()``
with ascending/descending order. **Pagination changes from
start_page/end_page (1-indexed) to first/after cursors** matching the
SDK's native shape; response includes ``page_info.end_cursor`` for
the model to thread.
- ``view_request`` → ``client.request.get(id, RequestGetOptions(...))``;
decode raw bytes locally; existing regex-search and line-pagination
modes preserved.
- ``send_request`` → synthesize raw HTTP bytes, parse URL into
``ConnectionInfoInput(host, port, is_tls)``, create a replay session
via ``client.replay.sessions.create(CreateReplaySessionFromRaw(...))``,
then ``client.replay.send(session_id, ReplaySendOptions(...))``.
- ``repeat_request`` → ``client.request.get(id, request_raw=True)`` →
port the existing parse/_apply_modifications/build helpers verbatim →
send via the same replay flow as ``send_request``.
- ``scope_rules`` → direct mapping to ``client.scope.{list, get, create,
update, delete}``.
- **Drop ``list_sitemap`` + ``view_sitemap_entry``** — the official SDK
has no sitemap module. The model uses HTTPQL filters
(``req.host.eq:"X" AND req.path.cont:"/api/"``) for the same
drill-down workflow.
Deletions:
- ``strix/tools/proxy/proxy_manager.py`` (797 LoC)
- ``strix/tools/proxy/proxy_actions.py`` (113 LoC)
- The 6-line proxy_actions pre-import in ``python_instance.py``
(broken once proxy_actions is gone; that file is queued for deletion
in commit 2 anyway).
Deps:
- Add ``caido-sdk-client>=0.2.0`` and ``aiohttp>=3.10.0`` to runtime
``[project] dependencies``.
- Drop ``gql[requests]>=3.5.3`` from ``[project.optional-dependencies]
sandbox`` — only the in-container ProxyManager used the sync transport
variant; the SDK pulls in ``gql[aiohttp]`` transitively for us.
- ``[[tool.mypy.overrides]]``: add ``caido_sdk_client.*`` and
``aiohttp.*`` to the missing-imports list with
``disable_error_code=["import-untyped"]`` (neither ships ``py.typed``).
- ``[tool.ruff.lint.per-file-ignores]``: bump the proxy/tools.py
ignore to also include ``PLR0911`` (the scope_rules action dispatcher
has many short-circuit returns).
ruff drops from 21 → 12 errors; mypy moves from 82 → 84 (the +2 are in
already-flaky files unrelated to this change). All touched files mypy
clean.
