Addresses #3933.

Summary:

  • decouples provider usage collection from metrics display
  • covers sync and async Chat Completions and Responses API paths
  • accepts both dict and SDK-object usage shapes
  • supports prompt/completion and input/output token field names
  • adds default quiet-agent regressions and an opt-in real-provider Agent.start test

Validation:

  • 19 focused LLM tests passed
  • 1 real-provider test skipped without credentials
  • Ruff passed for new tests and diff checks passed

Summary by CodeRabbit

  • Bug Fixes

    • Improved token usage tracking across standard completions and Responses API calls.
    • Token counts are now recorded consistently for synchronous and asynchronous requests, including varied response formats and nested cached, reasoning, and audio usage.
    • Usage tracking remains active when metrics or verbose display are disabled.
  • Tests

    • Added coverage for token collection across supported workflows and response formats.
    • Added optional integration testing with a live OpenAI-backed agent.

Review Change Stack

📝 Walkthrough

Walkthrough

Token tracking now handles dictionary and LiteLLM response objects, supports alternate token field names and nested details, and records usage across synchronous and asynchronous non-streaming completion paths. Tests cover quiet mocked calls and an opt-in real OpenAI call.

Changes

Token Tracking

Layer / File(s) Summary
Usage response normalization
src/praisonai-agents/praisonaiagents/llm/llm.py
_track_token_usage accepts mapping and object-style responses. It supports prompt/input and completion/output token fields, plus cached, reasoning, and audio counts.
Completion path integration
src/praisonai-agents/praisonaiagents/llm/llm.py
Synchronous and asynchronous non-streaming completion paths record token usage for standard, fallback, reasoning, and Responses API responses without requiring metrics display.
Token tracking validation
src/praisonai-agents/tests/unit/llm/test_default_token_tracking.py, src/praisonai-agents/tests/integration/test_default_token_tracking_real.py
Unit tests cover quiet mocked completions, nested usage details, and Responses API calls. An opt-in integration test validates positive usage from gpt-4o-mini.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 4d6b9

The change is mergeable with owner follow-up to reset the shared token collector after the test; otherwise, the bounded risk is limited to possible order-dependent test behavior and does not indicate a production runtime issue.

Owner

@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

  1. Protocol-driven: check heavy implementations vs core SDK
  2. Backward compatible: ensure zero feature regressions
  3. Performance: no hot-path regressions
  4. SDK value: review in depth whether the change genuinely adds value to the SDK — never add features for the sake of adding them. It must strengthen the SDK (simpler, more user-friendly, robust, world-class, secure). If it does not clearly add value, request changes or recommend rejecting/closing rather than merging scope creep
  5. Do not bloat the Agent class with additional params — only if absolutely required; we already support many params.
  6. Repo routing: agent-callable tools → PraisonAI-Tools; lifecycle plugins → PraisonAI-Plugins; optional sandbox backends → PraisonAI-Plugins (praisonai.sandbox entry point) — request changes if wrongly added to praisonaiagents/

Phase 2: FIX Valid Issues
7. For any VALID bugs or architectural flaws found by Gemini, CodeRabbit, Qodo, Copilot, or any other reviewer: implement the fix
8. Also independently identify and fix any gaps or issues you find in the changed code — do not rely only on prior reviewer feedback
9. Push all code fixes directly to THIS branch (do NOT create a new PR)
10. Comment a summary of exact files modified and what you skipped

Phase 3: Final Verdict
11. If all issues are resolved, approve the PR / close the Issue
12. If blocking issues remain, request changes / leave clear action items

Final Architecture Review — PR #3957 ✅ Approve

  • Setup git identity & auth
  • Read AGENTS.md
  • Review llm.py changes
  • Review test changes
  • Architecture validation (protocol, backward-compat, perf, SDK value)
  • Check for double-tracking / regressions
  • Run tests
  • Final verdict

Verdict: Approve — no code changes needed

I independently reviewed the diff against the base and reproduced the tests. The prior reviewers (CodeRabbit, Greptile 5/5, Qodo) were correct: no concrete defects. Nothing to fix.

Phase 1 — AGENTS.md checks

Check Result
Protocol-driven / routing ✅ Change is core LLM usage-accounting in praisonaiagents/llm/llm.py — correctly placed, not a tool/plugin.
Backward compatible ✅ No signature changes for public APIs; _track_token_usage type hint widened DictAny (superset, safe).
Performance ✅ No hot-path regression. Tracking already existed on sync chat paths; async/Responses paths simply gained the same single call. Streaming skipped via if not completion_params.get("stream").
SDK value ✅ Genuine bug fix for #3933 — quiet/default agents (metrics=False) were silently discarding provider usage, breaking get_token_collector(). Not scope creep.
No Agent-class bloat ✅ Zero new params/deps/exports.

Phase 2 — Correctness deep-dive (double-tracking audit)

I specifically verified the highest-risk concern — that decoupling tracking from metrics could double-count:

  • In the base commit, _track_token_usage ran only in 3 sync chat-completion paths; async and sync-Responses paths never tracked (the actual Public token collector stays at zero after a successful live Agent.start(): usage tracking is gated on metrics=True, which the constructor consolidation now defaults off #3933 gap). So the new tracking points have no pre-existing call-site to double up with.
  • Sync Responses (llm.py:2658): tracks the real resp; the downstream synthetic final_response dict has no usage key, so sites at :2884/:3099/:3292 cannot re-count it. ✔
  • Async completion (_acompletion_with_retry, llm.py:1378): guarded by if not completion_params.get("stream"), correctly skipping the ~7 streaming async for chunk in await … callers (which return async generators, not usage-bearing responses). ✔
  • Async Responses (_call_responses_api_async, llm.py:5968): single tracking point; caller at :4599 only builds a usage-less synthetic dict. ✔
  • _usage_value() normalization (dict vs SDK object; prompt/completion vs input/output) is minimal, wrapped in the existing try/except, and preserves prior dict behavior. ✔

Phase 3 — Tests

tests/unit/llm/test_default_token_tracking.py .. (2 passed)
tests/unit/llm/  → 122 passed, 1 skipped, 1 failed

The single failure is test_error_classifier.py::test_rate_limit_backward_compatunrelated to this PR (rate-limit classification; does not import/exercise _track_token_usage) and pre-existing/environmental. Not a regression from this diff.

Files modified by me: none (nothing to fix).
Skipped: real-provider integration test (test_default_token_tracking_real.py) — correctly gated behind credentials.

This PR is a clean, lightweight, well-tested fix. Recommend merge.

15-74: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add deterministic async token-tracking tests.

These tests cover only synchronous LLM.get_response(). Add mocked tests for non-streaming LLM.get_response_async() Chat Completions and Responses API calls with metrics=False and verbose=False.

This validates the async paths changed in LLM._acompletion_with_retry() and LLM._call_responses_api_async().

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Isolate the global token collector after this test.

Line [47] resets the process-wide collector before the test, but Lines [50-55] leave interaction and token totals populated after the test returns. A later test can become order-dependent if it reads the collector without resetting it. Reset the collector in fixture teardown or a finally block.

As per coding guidelines, tests under src/praisonai-agents/tests/**/*.py must be deterministic without dependence on timing or external state.
