Greptile SummaryThis PR follows up on #1853 by adding test coverage and three targeted production fixes: billing errors are now non-retryable (surfaced immediately), "quota exceeded" is reclassified as billing instead of rate_limit, and
Confidence Score: 4/5The production changes in llm.py are safe to merge. The test files added alongside them contain multiple broken assertions that will fail immediately on the first CI run. The three llm.py changes (billing non-retryable, billing-before-rate-limit ordering, max_iter default) are correct and well-scoped. The idle-timeout-breaker tests are accurate. However, test_error_classification.py has at least 8 individual test cases whose input strings do not match the classifier's actual indicator lists and will trigger assertion failures, making the claimed coverage invalid until corrected. src/praisonai-agents/tests/unit/test_error_classification.py — four test methods contain strings that do not match the indicators in classify_error_kind Important Files Changed

206-248: ⚡ Quick winConsider testing tool-call iteration limits via agent execution.
This test directly calls
llm.get_response()to verify max_iter enforcement in tool loops, which is better than pure constructor tests. However, for a true integration test, consider usingagent.start()with tools to verify the limit is enforced in the full agentic flow (Agent → LLM → tools → response). The bareExceptioncatch on line 245 is acceptable in test context to handle both success and exception paths.Source: Coding guidelines

check so callers can pass 0 or other falsy values intentionally; set
self.max_iter = 20 if max_iter is None else max_iter (and ensure the initializer
signature allows None as the default), updating the assignment that currently
uses "max_iter or 20" where self.max_iter is set.
- Around line 804-805: The patch added "billing" to the non-retryable list but
classify_error_kind() currently returns "rate_limit" for 429 cases, causing
billing errors to be retried; update classify_error_kind() to detect and return
"billing" before it tests/returns "rate_limit" (e.g., explicitly check for 429 +
billing-related text/headers and return "billing" early) so the existing
non-retryable check (if error_kind in ["auth_permanent", "model_not_found",
"format_error", "billing"]) correctly surfaces billing errors without retries.

praisonaiagents.agent.agent.LLM to control responses; assert the run produces a
response and that the mocked LLM received max_iter==12 (check
MockLLM.call_args.kwargs['max_iter']) during execution, and keep references to
Agent, ExecutionConfig, AutonomyConfig, Agent.start (or the actual start method)
and MockLLM to locate the changes.

prompt and await/collect its response to verify behavior, instead of only
asserting MockLLM.call_args; update the vague comment to a concrete assertion
that either (a) the produced run used the LLM default max_iter or (b)
Agent._exec_config provided the default max_iter by checking MockLLM was
constructed with the expected max_iter in MockLLM.call_args and/or by inspecting
the runtime behavior (e.g., number of iterations or responses returned). Ensure
you use the existing MockLLM and self.test_llm_config references and replace the
current placeholder comment with an explicit assert about max_iter or iteration
count after agent.start().
- Around line 121-151: The test test_different_llm_init_paths_respect_max_iter

that is the runtime entrypoint) after creating Agent(name=..., instructions=...,
llm=llm_config, execution=execution_config) and then assert the LLM was invoked
during execution and that iteration-limiting behavior occurred (e.g., MockLLM

the existing patch for LLM._chat_completion and the MockLLM instantiation, then
assert runtime behavior: verify the mocked LLM was actually invoked during
agent.start (e.g., mock_llm_instance._chat_completion/MockLLM.assert_called()),
confirm the agent produced a text response (non-empty string) and optionally
assert that the number of LLM calls or iterations respects max_iter (inspect
mock call count or any iteration-tracking on Agent) so the test both preserves
constructor checks (MockLLM.call_args contains 'max_iter':15) and validates
enforcement during Agent.start.

name: resolve_failover_decision, inspect uses of self._failover_manager and
classify_error_kind) to explicitly return a decision with action "surface_error"
and reason "auth" when classify_error_kind(error) == "auth" and
self._failover_manager is None (preserve existing behavior when
_failover_manager is present), or alternatively adjust the test to expect the
current retry behavior—pick the code change if the intent is to surface auth
errors without a failover manager.
- Around line 348-359: The test test_overloaded_retry_with_exponential_backoff
expects the wrong backoff value; update the assertion and its comment to match
resolve_failover_decision's formula (2000 * (2 ** (attempt - 1))). For
attempt_state = {"attempt": 2, "max_retries": 3} change the comment to reflect
2000 * (2 ** (2 - 1)) = 4000ms and update the assertion to assert
decision.backoff_ms == 4000 so the test matches the implementation.
- Around line 174-245: The test fixtures in test_billing_classification,
test_overloaded_classification, test_empty_response_classification, and
test_format_error_classification are out of sync with LLM.classify_error_kind
(the classifier at LLM.classify_error_kind) — update the test inputs or expected
labels to match the implementation rather than the current assumptions: remove
or replace strings not present in the classifier patterns (e.g. "subscription
expired", "try again later", "server busy", "no content", "blank output", "null
response") or change their expected outputs to whatever LLM.classify_error_kind
actually returns, and change the expectation for "malformed response" from
"format_error" to "empty_response" (or adjust the classifier if you prefer
feature change); ensure each test method (test_billing_classification,
test_overloaded_classification, test_empty_response_classification,
test_format_error_classification) only asserts labels that exist in
LLM.classify_error_kind.

Respect explicit max_iter values instead of silently coercing falsy input.
Line 409 uses max_iter or 20, so an explicit max_iter=0 is silently replaced with 20. That breaks explicit config propagation and can hide invalid input instead of surfacing it.

Billing non-retryable policy is currently bypassable by classification order.
Line 805 adds billing to non-retryable errors, but billing messages that include 429 are still classified as rate_limit first in classify_error_kind(). That causes retries instead of immediate surfacing for common quota/billing failures.

Integration test should execute the agent via agent.start(), not just verify constructor wiring.
Per coding guidelines: "Real agentic tests are MANDATORY for every feature: Agent must call agent.start() with a real prompt, call the LLM, and produce actual text response—not just smoke tests of object construction." This test constructs an agent and verifies max_iter is passed to the LLM constructor, but never executes the agent to confirm the limit is enforced during actual agentic flow.

Test expects old default value; will fail after LLM default increase.
According to the PR changes in the same cohort ("LLM constructor now defaults max_iter to 20 instead of 10 when not explicitly provided"), the LLM default was increased to 20. This test still expects 10 and will fail. The TODO comment confirms this mismatch was known but not fixed.

- # Currently defaults to 10, should be aligned with ExecutionConfig default (20)
assert hasattr(llm, 'max_iter')
- # This documents current behavior - will be fixed in implementation

Integration test should execute the agent, not just verify wiring.
This test creates an agent but never calls agent.start() to verify that max_iter behavior works end-to-end. Additionally, the comment on lines 106-108 is vague ("This verifies the current wiring behavior") and doesn't make a clear assertion about expected behavior. Per coding guidelines, integration tests must execute the agent with a real prompt and produce actual responses.

Integration test should execute agents with different LLM initialization paths.
While this test verifies that max_iter is passed to the LLM constructor across different initialization paths (dict, string, base_url), it never calls agent.start() to confirm the limit is actually enforced during execution. Per coding guidelines, integration tests must execute the agent flow, not just verify constructor wiring.

llm=llm_config, execution=execution_config) and then assert the LLM was invoked
during execution and that iteration-limiting behavior occurred (e.g., MockLLM
instance call count or a mocked step method was not called more than 30 times);
ensure you still reset MockLLM between test cases and keep the assertions that
call_args.kwargs['max_iter']==30.

🛠️ Refactor suggestion | 🟠 Major | 🏗️ Heavy lift
Integration test should verify autonomy + max_iter in actual execution.
This test creates an agent with both ExecutionConfig and AutonomyConfig but never calls agent.start() to verify they work together during actual agent execution. Per coding guidelines, integration tests must execute the agent with a real prompt and produce responses, not just verify that configs can coexist in the constructor.

Several classifier fixtures don't match LLM.classify_error_kind().
These cases are currently out of contract with src/praisonai-agents/praisonaiagents/llm/llm.py:697-784, so the unit suite will fail as written. Examples: Line 180 "subscription expired" is not in the billing patterns; Lines 194-195 ("try again later", "server busy") are not overloaded patterns; Lines 222-224 ("no content", "blank output", "null response") are not empty-response patterns; and Line 236 "malformed response" is classified as empty_response, not format_error, because that branch runs first.

This assertion is ahead of the current auth failover logic.
With the supplied resolve_failover_decision() implementation in src/praisonai-agents/praisonaiagents/llm/llm.py:786-876, "auth" only returns "rotate_profile" when _failover_manager exists. Otherwise it falls through to the default retry branch, so Line 329 will fail unless the production code also adds an explicit "auth" -> "surface_error" path.

The expected overloaded backoff is off by one step.
resolve_failover_decision() uses 2000 * (2 ** (attempt - 1)), so attempt = 2 yields 4000, not 2000. The assertion on Line 359 and the comment above it currently disagree with the supplied implementation.
