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.
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.
