Network spy #115

dimavrem22 · 2026-01-29T20:44:26Z

[Alex] Async CDP monitors + unit tests
[Ray] DOM monitor
light refactor of network monitoring module:
- moved constants out
- track minor data for providing summary to agents
- no fetch requests are blocked, but we skip logging telemetry, tracking, and analytics
Adapted the (soon to be deprecated) data store to use the data from async monitors:
- required edits to guide agent and quick start scripts
NEW data store for network monitoring:
- first attempt of a data store that removes the need for vectorstores
- reads new data format from async monitors
- implements convenience functions that allow agent to quickly query the network traffic data
- unit tests added
Network SPY (beta): [THIS AGENT IS NOT FINALIZED - WILL BE FINALIZED WHEN WE REFACTOR DISCOVERY]
- agent that has access to new network data store and tools to interact with it
- autonomous mode allows mimicking first step of routine discovery (takes 5-10s on avg)
- run_network_spy script allows chatting with network spy agent
To run network spy:
python scripts/run_network_spy.py --jsonl-path ./cdp_captures/network/events.jsonl

To test how this will fit into discovery, use /autonomous <TASK>

into collect_dom_data

DOM Data Monitor

into network-spy

Code Review

I've completed a thorough review of PR #115 and found 6 issues that need to be addressed:

CLAUDE.md Violations

1. Lazy imports in `bluebox/agents/network_spy.py`

Lines 733-734:

bluebox-sdk/bluebox/agents/network_spy.py

Lines 731 to 738 in 0e5f82d

    
           def _tool_execute_python(self, tool_arguments: dict[str, Any]) -> dict[str, Any]: 
        
               """Execute Python code with har_dict pre-loaded from NetworkDataStore.""" 
        
               import io 
        
               import sys 
        
               code = tool_arguments.get("code", "") 
        
               if not code: 
        
                   return {"error": "No code provided"}

import io
import sys

According to CLAUDE.md L49:

IMPORTANT: NO lazy imports! All imports must be at the top of the file

Fix: Move these imports to the top of the file.

2. Lazy import in `bluebox/sdk/discovery.py`

Line 87:

bluebox-sdk/bluebox/sdk/discovery.py

Lines 85 to 91 in 0e5f82d

    
           def _default_message_handler(self, message: RoutineDiscoveryMessage) -> None: 
        
               """Default message handler that logs to console.""" 
        
               from bluebox.data_models.routine_discovery.message import RoutineDiscoveryMessageType 
        
               if message.type == RoutineDiscoveryMessageType.INITIATED: 
        
                   logger.info(f"🚀 {message.content}") 
        
               elif message.type == RoutineDiscoveryMessageType.PROGRESS_THINKING:

from bluebox.data_models.routine_discovery.message import RoutineDiscoveryMessageType

According to CLAUDE.md L49:

IMPORTANT: NO lazy imports! All imports must be at the top of the file

Fix: Move this import to the top of the file alongside the existing import from the same module.

Bugs

3. 🔴 CRITICAL: Arbitrary code execution via `execute_python` tool

File: bluebox/agents/network_spy.py, line 753

bluebox-sdk/bluebox/agents/network_spy.py

Lines 750 to 758 in 0e5f82d

    
               "har_dict": har_dict, 
        
               "json": json, 
        
           } 
        
           exec(code, exec_globals)  # noqa: S102 
        
           output = captured_output.getvalue() 
        
           return { 
        
               "output": output if output else "(no output)", 
        
           }

The _tool_execute_python method uses exec() to execute arbitrary Python code without sandboxing:

exec_globals = {
    "har_dict": har_dict,
    "json": json,
}
exec(code, exec_globals)  # noqa: S102

Security Risk: The LLM analyzes network traffic that could contain malicious content. An attacker could embed prompt injection payloads in HTTP responses, headers, or URLs to trick the LLM into generating malicious code. The exec() has no restrictions on imports or builtins, allowing full system access.

Attack chain: Malicious network traffic → LLM context → prompt injection → LLM calls execute_python → arbitrary code execution

Recommendation: Either:

Remove this tool entirely if not essential
Implement proper sandboxing (restricted builtins, no imports, timeout)
Use a safer alternative like AST-based expression evaluation for limited operations

4. `unique_terms_found` double-counts terms across search scopes

File: bluebox/agents/network_spy.py, lines 804-820

bluebox-sdk/bluebox/agents/network_spy.py

Lines 800 to 832 in 0e5f82d

    
           if "headers" in search_in: 
        
               headers_str = json.dumps(entry.request_headers).lower() 
        
               for term in terms_lower: 
        
                   count = headers_str.count(term) 
        
                   if count > 0: 
        
                       unique_terms_found += 1 
        
                       total_hits += count 
        
                       if "headers" not in matched_in: 
        
                           matched_in.append("headers") 
        
           # Search body 
        
           if "body" in search_in and entry.post_data: 
        
               post_data_str = json.dumps(entry.post_data) if isinstance(entry.post_data, (dict, list)) else str(entry.post_data) 
        
               body_lower = post_data_str.lower() 
        
               for term in terms_lower: 
        
                   count = body_lower.count(term) 
        
                   if count > 0: 
        
                       unique_terms_found += 1 
        
                       total_hits += count 
        
                       if "body" not in matched_in: 
        
                           matched_in.append("body") 
        
           if unique_terms_found > 0: 
        
               score = (total_hits / len(terms_lower)) * unique_terms_found 
        
               results.append({ 
        
                   "id": entry.request_id, 
        
                   "method": entry.method, 
        
                   "url": entry.url, 
        
                   "matched_in": matched_in, 
        
                   "unique_terms_found": unique_terms_found, 
        
                   "total_hits": total_hits, 
        
                   "score": round(score, 2), 
        
               })

The unique_terms_found counter is incremented for each term found in each scope (url, headers, body) independently:

if count > 0:
    unique_terms_found += 1  # Incremented per scope
    total_hits += count

Bug: If term "api" appears in both URL and headers, unique_terms_found becomes 2 instead of 1, inflating the relevance score.

Impact: With 3 terms each appearing in all 3 scopes, unique_terms_found would be 9 instead of 3, inflating scores by 3x.

Fix: Track found terms in a set and count unique terms only once:

found_terms = set()
# ... in each scope loop:
if count > 0:
    found_terms.add(term)
    total_hits += count
# ... after all scopes:
unique_terms_found = len(found_terms)

5. Hardcoded max iterations in autonomous mode

File: bluebox/agents/network_spy.py, line 1348

bluebox-sdk/bluebox/agents/network_spy.py

Lines 1345 to 1359 in 0e5f82d

    
           # Add finalize tool availability notice 
        
           if self._finalize_tool_registered: 
        
               # Get urgency based on iteration count 
        
               remaining_iterations = 10 - self._autonomous_iteration 
        
               if remaining_iterations <= 2: 
        
                   finalize_notice = ( 
        
                       f"\n\n## CRITICAL: YOU MUST CALL finalize_result NOW!\n" 
        
                       f"Only {remaining_iterations} iterations remaining. " 
        
                       f"You MUST call `finalize_result` with your best findings immediately. " 
        
                       f"Do NOT call any other tool - call finalize_result right now!" 
        
                   ) 
        
               elif remaining_iterations <= 4: 
        
                   finalize_notice = ( 
        
                       f"\n\n## URGENT: Call finalize_result soon!\n" 
        
                       f"Only {remaining_iterations} iterations remaining. "

remaining_iterations = 10 - self._autonomous_iteration

Bug: The run_autonomous method accepts a configurable max_iterations parameter (default 10), but _get_autonomous_system_prompt hardcodes 10 when computing remaining iterations.

Impact: If caller passes max_iterations=20, urgency notices trigger prematurely (at iteration 8 instead of 18), causing incorrect LLM behavior.

Fix: Pass max_iterations to _get_autonomous_system_prompt and use it:

remaining_iterations = max_iterations - self._autonomous_iteration

6. `sessionId` attached to all CDP commands including browser-level commands

File: bluebox/cdp/async_cdp_session.py, lines 259-260

bluebox-sdk/bluebox/cdp/async_cdp_session.py

Lines 255 to 264 in 0e5f82d

    
               "id": cmd_id, 
        
               "method": method, 
        
               "params": params or {}, 
        
           } 
        
           if self.page_session_id: 
        
               msg["sessionId"] = self.page_session_id 
        
           msg_json = json.dumps(msg) 
        
           await self.ws.send(msg_json) 
        
           return cmd_id

if self.page_session_id:
    msg["sessionId"] = self.page_session_id

Bug: The code unconditionally attaches page_session_id to ALL CDP commands. However, browser-level commands (e.g., Target.getTargets, Target.attachToTarget) should NOT include a sessionId.

Impact: Sending sessionId with browser-level commands routes them to the wrong target, causing CDP protocol errors.

Fix: Only attach sessionId to page-level commands:

if self.page_session_id and is_page_level:
    msg["sessionId"] = self.page_session_id

(The is_page_level check already exists at line 241 for warning purposes.)

Commit and push changes

Root Cause

The 400 error occurred in bluebox/agents/network_spy_agent.py:640 when constructing messages for the OpenAI API. The code was using the wrong field name for tool calls.

Issue: The code used "call_id" as the field name, but the OpenAI API requires "id":

msg["tool_calls"] = [
    {
        "call_id": tc.call_id,  # ❌ Wrong - API expects "id"
        "name": tc.tool_name,
        "arguments": tc.tool_arguments,
    }
]

This caused the API to see null for the required tool_calls[0].id field, resulting in:

Error code: 400 - {'error': {'message': "Invalid type for 'messages[2].tool_calls[0].id': 
expected a string, but got null instead."}}

Fix Applied

Changed "call_id" to "id" in the tool_calls dictionary:

msg["tool_calls"] = [
    {
        "id": tc.call_id if tc.call_id else f"call_{idx}_{chat_id[:8]}",  # ✓ Correct
        "name": tc.tool_name,
        "arguments": tc.tool_arguments,
    }
]

The fix has been committed and pushed to the network-spy branch.

| Branch: network-spy

The OpenAI API expects tool_calls to have an 'id' field, not 'call_id'. This was causing a 400 error: 'Invalid type for messages[2].tool_calls[0].id: expected a string, but got null instead.' Co-authored-by: Ruizhi (Ray) Liao <[email protected]>
