Code Review
This pull request introduces automatic retry support with exponential backoff and jitter for transient tool failures by adding the ToolRetryConfig configuration class and integrating it into the agent's tool execution flow. The feedback highlights a critical runtime bug where ToolExecutionError is instantiated with an unsupported error_category keyword argument. Additionally, the reviewer suggests resolving tool_retry_config from booleans or dictionaries for API consistency, replacing self.name with self.display_name to handle nameless agents safely, and scaling the jitter calculation proportionally with the backoff delay.

CRITICAL BUG: ToolExecutionError.__init__ does not accept error_category as a keyword argument. Passing it directly will raise a TypeError at runtime, completely breaking the retry mechanism when a tool returns an error dictionary. Instead, instantiate the error first and set the error_category attribute on it. Also, use self.display_name to avoid None values for nameless agents, and convert result["error"] to a string defensively.
error_msg = str(result["error"])
is_retryable = True
# Determine error category from the error dict or message
if result.get("circuit_open"):
error_category = "circuit_breaker"
elif 'timeout' in error_msg.lower():
error_category = 'timeout'
elif 'network' in error_msg.lower() or 'connection' in error_msg.lower():
error_category = 'network'
elif 'rate limit' in error_msg.lower() or 'too many requests' in error_msg.lower():
error_category = 'rate_limit'

To maintain consistency with other configuration parameters in the PraisonAI Agent API (such as memory, knowledge, planning, etc.), tool_retry_config should support resolution from a boolean (e.g., True to enable with defaults) or a dictionary of configuration fields, rather than strictly requiring a ToolRetryConfig instance.

Using self.name directly can result in None for nameless agents. It is safer and more robust to use self.display_name which is guaranteed to return a valid string identifier.

The current jitter calculation uses retry_config.jitter * retry_config.initial_delay_s, which remains constant across all retry attempts. To effectively prevent thundering herd collisions at higher retry attempts, the jitter should scale proportionally with the calculated backoff delay.

Confidence Score: 3/5Not safe to merge as-is — the refactor accidentally removed prompt-injection protection for external tools, and the timeout boundary now swallows retries.

|
| Filename | Overview |
|---|---|
| src/praisonai-agents/praisonaiagents/agent/tool_execution.py | Core refactor introduces _execute_tool_with_retry_support; removes wrap_if_external call (security regression) and wraps the entire retry loop inside the per-call timeout boundary (breaks retry when _tool_timeout is set). |
| src/praisonai-agents/praisonaiagents/agent/tool_execution_fixed.py | Orphaned draft file — defines a partial ToolExecutionMixin that is never imported anywhere; should be removed. |
| src/praisonai-agents/praisonaiagents/config/feature_configs.py | Adds ToolRetryConfig dataclass with validated fields; validation in __post_init__ looks correct. |
| src/praisonai-agents/praisonaiagents/agent/agent.py | Adds tool_retry_config parameter to Agent with consistent bool/dict/instance normalization. |
| src/praisonai-agents/praisonaiagents/hooks/events.py | Fixes duplicate attempt field in OnRetryInput, renames delay_seconds to retry_delay_seconds; legacy fields retained. |
| src/praisonai-agents/praisonaiagents/config/init.py | Exports ToolRetryConfig via __all__ and _MODULE_MAP; straightforward bookkeeping change. |

src/praisonai-agents/praisonaiagents/agent/tool_execution.py, line 20 (link)Prompt-injection protection silently dropped
The refactor removed the
wrap_if_external(function_name, result)call that previously ran after every tool execution.wrap_if_externalis still imported at line 20, but no longer called anywhere in the file. Any agent that uses external tools (internet_search,duckduckgo,tavily_search,scrape_page, etc.) will now return raw, unwrapped content to the model instead of content fenced inside<external_tool_result>markers. Prompt injection payloads embedded in web pages or search results will reach the LLM instruction stream directly, with no mitigation. The fix is to addresult = wrap_if_external(function_name, result)after the retry block (around line 356), immediately before the truncation step.

_execute_tool_with_retry_support is only called from the synchronous execute_tool path (lines 244 and 261 of this file). The async agent chat loop — the primary execution path — passes execute_tool_fn=self.execute_tool_async (in chat_mixin.py lines 1021 and 2173). execute_tool_async in execution_mixin.py calls tools directly and has no retry mechanism. As a result, any agent created with tool_retry_config=ToolRetryConfig(...) will silently ignore the configuration during normal chat()/achat() operation, defeating the entire purpose of the feature.

time.sleep blocks the event loop when the sync bridge is active
When _execute_tool_with_retry_support is called on the non-timeout path (line 261), time.sleep(delay) runs on the calling thread. If execute_tool is invoked from a synchronous bridge over a running event loop (e.g., loop.run_until_complete), this blocks the entire event loop for the full retry delay — potentially several seconds per attempt. The retry delay should either be shifted into the ThreadPoolExecutor path (already used for the timeout case) or, for a proper async-aware retry, moved to asyncio.sleep in the async path.

In `@src/praisonai-agents/praisonaiagents/agent/agent.py`:
- Around line 1522-1540: Locate the clone_for_channel() method in the Agent
class and update the creation of the new Agent instance to include the
tool_retry_config parameter, passing self.tool_retry_config as its value. This
ensures that when agents are cloned for a channel, the tool retry configuration
is preserved from the original agent to the cloned agent.
- Line 600: The tool_retry_config parameter has inconsistent type annotation and
documentation compared to its runtime behavior. Update the type annotation on
the parameter definition to use Union type to document that it accepts None,
False, True, dict, and ToolRetryConfig instance (not just Optional
ToolRetryConfig). Update the docstring to document all these accepted types.
Additionally, the clone_for_channel() method is missing tool_retry_config from
its kwargs propagation, so add tool_retry_config to the cloned agent
configuration in the clone_for_channel() method's kwargs to ensure the
configuration is preserved during agent cloning.
In `@src/praisonai-agents/praisonaiagents/agent/tool_execution_fixed.py`:
- Around line 103-109: The list comprehension in the annotation handling block
uses `!=` comparison with `type(None)` instead of the identity comparison
operator `is not`. In the line where types are filtered from
`annotation.__args__`, replace the `!= type(None)` comparison with `is not
type(None)` to comply with Ruff E721 style guidelines and properly use identity
comparison for type checking.
- Around line 27-132: The file tool_execution_fixed.py is dead code and a merge
artifact that should be removed entirely. It is not imported anywhere in the
codebase; instead, agent.py (line 20) imports the complete mixin from
tool_execution.py. Since tool_execution_fixed.py contains only partial duplicate
helper methods and the full, actively-used mixin already exists in
tool_execution.py, delete the entire tool_execution_fixed.py file to eliminate
maintenance burden and reduce code duplication.
In `@src/praisonai-agents/praisonaiagents/agent/tool_execution.py`:
- Around line 886-900: The error_category values being assigned (timeout,
network, rate_limit, tool) may not match the category names expected in
retry_config.retryable_on due to naming inconsistencies elsewhere in the file
(such as connection_error vs network). Before comparing error_category to
retry_config.retryable_on on line 900, create a mapping or normalization logic
that standardizes the error_category names to ensure they match the expected
values in the retry configuration. This ensures that retryable errors are
properly matched regardless of which naming convention was used to classify the
error.
- Around line 330-355: The current implementation calls future.cancel() when a
timeout occurs, but this does not actually stop the running thread, allowing
_execute_tool_with_retry_support() to continue retrying in the background and
waste executor resources. Modify _execute_tool_with_retry_support() to accept a
deadline parameter (calculated from tool_timeout at the point of execution),
then add deadline checks before each sleep and retry attempt in the retry loop
so that retries stop immediately once the timeout deadline is reached,
preventing any background continuation after the timeout is returned to the
caller.
- Around line 871-873: Replace the call to
`_execute_tool_with_circuit_breaker()` at line 872 with a no-retry execution
primitive (a base execution method that does not contain retry logic). Move the
retry logic from within `_execute_tool_with_circuit_breaker()` to the current
method so that retry attempts are centralized and controlled by the
ToolRetryConfig filter. Add logic to classify and handle retryable error
dictionaries (those with `{"error": ...}` structure) within this method before
returning, ensuring that the new ToolRetryConfig retry policy controls all retry
behavior and prevents retry attempt multiplication.
- Around line 925-941: The `OnRetryInput` object being created in the `ON_RETRY`
hook emission is missing critical tool context information. Add the `tool_name`
field and a `target` field (representing the function name) to the retry_input
construction to align with the existing retry hook path and ensure hook
consumers can properly identify and filter retries by the tool being executed.
These fields should capture the relevant tool information from the current
execution context to provide complete attribution of the retry event.
In `@src/praisonai-agents/praisonaiagents/config/feature_configs.py`:
- Around line 1412-1425: The __post_init__ method in this configuration class
validates multiple parameters but does not validate the retryable_on field,
allowing invalid entries to pass through and fail later at runtime during retry
filtering. Add validation logic in __post_init__ after the existing parameter
checks to validate the contents of the retryable_on field, ensuring each entry
is of the appropriate type (likely exception classes), and raise a descriptive
ValueError if any invalid entries are found, so configuration errors are caught
immediately at initialization time rather than during runtime retry operations.
In `@src/praisonai-agents/praisonaiagents/hooks/events.py`:
- Around line 183-193: The retry event structure in the RetryEvent class has
inconsistent delay field handling and is dropping the legacy delay_seconds key,
breaking backward compatibility for downstream consumers. In the RetryEvent
definition (around line 183-193), add back the legacy delay_seconds field and
ensure it's consistently populated alongside the newer delay_ms and
retry_delay_seconds fields. Additionally, at the location where the retry event
payload is constructed (line 204-209), normalize the delay values so that all
three delay-related keys (delay_seconds, delay_ms, and retry_delay_seconds) are
included in the event payload, with appropriate unit conversions where needed,
to maintain backward compatibility while supporting current delay field usage.
In `@src/praisonai-agents/test_retry_fix.py`:
- Line 39: Replace all `assert False` statements with explicit `raise
AssertionError()` calls to prevent test validation from being silently skipped
when Python runs with optimization flags (python -O). This affects three
locations in the test file: the statement at line 39 that validates ValueError
should be raised, the one at line 47, and the one at line 55. Each `assert
False` statement should be replaced with `raise AssertionError()` to ensure
these validation checks always execute regardless of Python optimization
settings.
- Line 26: In the test_retry_fix.py file, simplify the assertion statement that
checks err.is_retryable by removing the redundant `== True` comparison. Change
the assertion from comparing the boolean attribute to True to directly asserting
the attribute itself, making the code more idiomatic and cleaner.

Nitpick comments:
In `@src/praisonai-agents/test_retry_fix.py`:
- Around line 1-86: The test_retry_fix.py file containing test functions like
test_error_category_attribute and test_retry_config_validation is currently
located in the src/praisonai-agents/ directory which mixes tests with source
code. Move this test script to a dedicated tests/ directory at the project root
to follow Python packaging conventions and improve project organization. Update
any import paths in the script if necessary to maintain correct module
resolution from the new location.
In `@src/praisonai-agents/test_tool_retry.py`:
- Around line 76-84: The __main__ block currently executes only
test_only_imports() while leaving test_tool_retry_config_import() and
test_agent_with_retry_config() undefined and unused. Either modify the __main__
block to run all three test functions sequentially (testing that all conditions
pass) or add a clear comment explaining why only the import test is being run.
If these other test functions are not needed, consider removing them entirely to
avoid confusion.

Add tool_retry_config to clone propagation and align type annotation/documentation with runtime behavior.
The tool_retry_config parameter accepts None, False, True, dict, and ToolRetryConfig instance at runtime (lines 1526–1540), but the type annotation (line 600) and docstring (line 717–720) only describe ToolRetryConfig instance. Additionally, clone_for_channel() omits tool_retry_config from the cloned configuration, causing state loss during agent cloning.
💡 Required fixes
- Update type annotation to document all accepted forms:
- tool_retry_config: Optional['ToolRetryConfig'] = None, # Automatic retry/backoff for tool failures
+ tool_retry_config: Optional[Union[bool, Dict[str, Any], 'ToolRetryConfig']] = None, # Automatic retry/backoff for tool failures- Update docstring to document all accepted types:
tool_retry_config: Automatic retry with exponential backoff for transient tool failures.
When configured, retryable ToolExecutionErrors (network timeouts, rate limits,
external service errors) will automatically retry before surfacing to the model.
- Default: None (no retry, preserves current behavior). Accepts ToolRetryConfig instance.
+ Default: None (no retry, preserves current behavior). Accepts:

tool_retry_config parameter has inconsistent type annotation and documentation

Preserve tool_retry_config when cloning agents.
self.tool_retry_config is now set here, but clone_for_channel() doesn’t pass it into the new Agent(...), so cloned agents silently lose tool retry/backoff behavior.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Prevent retries from continuing after the caller-visible timeout.
future.cancel() does not stop a running thread, so a timed-out _execute_tool_with_retry_support() can keep sleeping/retrying in the background and occupy the 2-worker executor. Pass a deadline/cancellation signal into the retry helper and check it before each sleep/attempt, or move timeout enforcement inside the retry loop so no retry runs after the tool timeout has been returned to the agent.

330 - 355, The current implementation calls future.cancel() when a timeout
occurs, but this does not actually stop the running thread, allowing
_execute_tool_with_retry_support() to continue retrying in the background and
waste executor resources. Modify _execute_tool_with_retry_support() to accept a
deadline parameter (calculated from tool_timeout at the point of execution),
then add deadline checks before each sleep and retry attempt in the retry loop
so that retries stop immediately once the timeout deadline is reached,
preventing any background continuation after the timeout is returned to the
caller.

Include tool context in the retry hook payload.
The new ON_RETRY emission omits tool_name and does not pass target=function_name, unlike the existing retry hook path. Hook consumers cannot reliably filter or attribute retries to a tool.

925 - 941, The `OnRetryInput` object being created in the `ON_RETRY` hook
emission is missing critical tool context information. Add the `tool_name` field
and a `target` field (representing the function name) to the retry_input
construction to align with the existing retry hook path and ensure hook
consumers can properly identify and filter retries by the tool being executed.
These fields should capture the relevant tool information from the current
execution context to provide complete attribution of the retry event.

1412 - 1425, The __post_init__ method in this configuration class validates
multiple parameters but does not validate the retryable_on field, allowing
invalid entries to pass through and fail later at runtime during retry
filtering. Add validation logic in __post_init__ after the existing parameter
checks to validate the contents of the retryable_on field, ensuring each entry
is of the appropriate type (likely exception classes), and raise a descriptive
ValueError if any invalid entries are found, so configuration errors are caught
immediately at initialization time rather than during runtime retry operations.

The retry event structure in the RetryEvent class has inconsistent delay field
handling and is dropping the legacy delay_seconds key, breaking backward
compatibility for downstream consumers. In the RetryEvent definition (around
line 183-193), add back the legacy delay_seconds field and ensure it's
consistently populated alongside the newer delay_ms and retry_delay_seconds
fields. Additionally, at the location where the retry event payload is
constructed (line 204-209), normalize the delay values so that all three
delay-related keys (delay_seconds, delay_ms, and retry_delay_seconds) are
included in the event payload, with appropriate unit conversions where needed,
to maintain backward compatibility while supporting current delay field usage.
