feat(agents): propagate tool_call_id through middleware context - #4023
Conversation
📝 WalkthroughWalkthroughThe change forwards each tool call’s ID through async dispatch and middleware context metadata. Unit tests verify ID propagation for synchronous and asynchronous execution paths. ChangesTool-call identity propagation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change forwards tool-call identity to middleware, but the required end-to-end agent-flow test is still missing to verify that the identity survives a real tool invocation; merge should wait until that validation is added.

@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Focus ONLY on Python packages (praisonaiagents, praisonai). Do NOT modify praisonai-rust or praisonai-ts. Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding. Phase 1: Review per AGENTS.md

Greptile SummaryThe PR exposes each originating tool-call identifier through middleware invocation metadata and forwards the identifier through the legacy asynchronous chat path.
Confidence Score: 5/5The PR appears safe to merge, with tool-call identity consistently propagated through the changed middleware and legacy async paths. The changed paths pass the existing identifier into middleware metadata while preserving the established execution flow, and no concrete behavioral, compatibility, or security failure remains.

Add the required real agentic test.
These tests call tool execution or _achat_completion directly. They do not call agent.start() with a real prompt, invoke the LLM, and print the full output. Add the required agentic test in the appropriate test category. Verify that the provider-originated tool-call ID reaches middleware during the full agent flow.
src/praisonai-agents/tests/unit/hooks/test_tool_call_identity_context.py#L10-L68: retain these unit tests and add coverage for the full agent flow.src/praisonai-agents/tests/unit/agent/test_achat_unified_dispatch.py#L88-L122: include legacy dispatch in the real agentic coverage if that path remains supported.
As per coding guidelines, “Every feature requires both smoke tests and a real agentic test in which an Agent calls agent.start() with a real prompt, invokes the LLM, and prints the full output.”

Hi Mervin, thanks again for merging the tool_call identity changes. One thing we noticed while testing this pattern across different agent runtimes is that preserving tool identity is only one part of the lifecycle. The harder boundary seems to be separating policy decision from execution outcome (for example ASK vs DENY vs handler failure). Curious whether PraisonAI has any plans around exposing more structured lifecycle states for these cases, or if this is something better handled at middleware level. |
Problem
Tool middleware lacks stable access to the originating tool-call identity across the sync, async, and legacy async chat dispatch paths.
Change
tool_call_idintoInvocationContext.metadatafor sync and async middleware execution.Value
Any middleware can correlate a decision or result with the original tool invocation without adding vendor-specific logic to core.
