Co-authored-by: Dhivya-Bharathy <[email protected]>
2026-06-08 07:47:16 +01:00
praisonai-triage-agent[bot]andMervin Praison 8b4db44159 fix: resolve Gemini reviewer issues - remove redundant arguments and fix temp file pollution
- Remove redundant argument from workflow.run() in basic_workflow.py since variables are already set in constructor
- Fix temp file pollution by using system temp directory instead of repository directory in auto_rag_agent_basic.py and knowledge-agents-task.py

Build context with cache boundary markers for prompt prefix caching optimization.
Returns a dictionary with 'stable_prefix' and 'cache_boundary' keys.
The stable prefix contains deterministically ordered content that should
remain constant between turns for effective prompt caching.

user_id: Optional user ID for personalized memory
additional: Additional context to include in search
max_items: Maximum items per memory category
