Thinking content was previously returned as non-standard top-level
fields (thinking, thinking_duration). Now follows the official OpenAI
Responses API format:
- Reasoning appears as a 'type: reasoning' item in the output array
with summary[].text containing the thinking content
- Message item follows after the reasoning item
- thinking_signature kept as proxy extension (internal multi-turn data)
- Removed ResponseOutput/OutputContent structs in favor of
serde_json::Value for polymorphic output items
Tools are only needed by the Antigravity webview for tool-call UI.
Our proxy doesn't need them — the model generates text responses fine
without tool definitions. Stripping all 20 tools saves ~15KB per request.
- Only set HTTPS_PROXY/HTTP_PROXY when iptables UID isolation is NOT
available. With iptables, double-proxying caused profile picture
fetches to fail with 'lookup http' DNS errors.
- Fix is_agent detection: handle JSON with spaces after colons
("requestType": "agent" vs "requestType":"agent")
- Suppress wrapper-not-installed warning in standalone mode
- Show 'iptables (standalone)' in banner instead of 'not installed'
When the MITM can't extract a cascade ID from the intercepted request
(Content-Length: 0 / chunked encoding), usage is stored under '_latest'.
Now usage_from_poll and completions try the exact cascade_id first,
then fall back to '_latest' so MITM-captured tokens are actually used.
- Spawn standalone LS as dedicated 'antigravity-ls' user via sudo
- UID-scoped iptables redirect (port 443 → MITM proxy) via mitm-redirect.sh
- Combined CA bundle (system CAs + MITM CA) for Go TLS trust
- Transparent TLS interception with chunked response detection
- Google SSE parser for streamGenerateContent usage extraction
- Timeouts on all MITM operations (TLS handshake, upstream, idle)
- Forward response data immediately (no buffering)
- Per-model token usage capture (input, output, thinking)
- Update docs and known issues to reflect resolved TLS blocker
