Summary

Refactored the embedded tool call removal logic to use a more precise regex pattern that only matches complete tool call markers (<< {...} >>), preventing accidental removal of unmatched << operators (like shell/Terraform heredocs or C++ operators) that may appear in Holmes responses.

Key Changes

• Extracted regex pattern and functions: Created EMBEDDED_TOOL_CALL_RE constant with improved pattern (<<\s*\{.*?\}\s*>>) that only matches complete JSON-wrapped tool calls, and extracted strip_embedded_tool_calls() helper function
• Fixed streaming response handling: Introduced strip_embedded_tool_calls_from_answer() function that applies stripping only to specific answer text fields (analysis, content) rather than the entire SSE event, preventing JSON corruption from regex operations on raw event data
• Updated both code paths: Applied the new stripping logic to both the holmes_chat() function and the stream_and_render_graphs() streaming handler
• Added comprehensive test: Added test_holmes_chat_streaming_keeps_unmatched_heredoc_in_answer() to verify that unmatched << operators in answers are preserved while embedded tool calls are correctly removed, and that conversation history remains intact

Implementation Details

The original regex pattern r"<<.*?>>" was too greedy and would match from the first << to the first >>, potentially spanning across multiple fields in the JSON response and corrupting the data structure. The new pattern requires a JSON object between the markers and operates only on the relevant text fields, ensuring safe removal of tool call markers without side effects.

Walkthrough

Graph rendering removes embedded JSON tool-call markers from answer text. Streaming sanitization applies only to the analysis and content string fields in answer-end events. Other event data is preserved.

Changes

Answer marker sanitization

Layer / File(s)	Summary
Marker removal and validation src/robusta/core/playbooks/internal/ai_integration.py, tests/test_ai_integration.py	Graph rendering removes matching markers from answer text. Streaming sanitization changes only analysis and content string fields and preserves other event data. The regression test checks heredoc text and unchanged conversation_history.

Full details: Docstring Coverage

Explanation

Docstring coverage is 33.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
