Confidence Score: 3/5Not safe to merge without fixes: the native sandbox config raises an unhandled ValueError, the context manager leaks resources when stop fails, and most of the new test suite would fail on first run. Three independent defects in newly added code: SandboxConfig.native() produces a type the manager cannot dispatch, aexit skips cleanup whenever stop() throws, and the test file references methods and patch targets that do not exist. Focus on sandbox/manager.py (aexit cleanup logic), sandbox/config.py (native type routing), and tests/unit/sandbox/test_sandbox_manager.py (non-existent method and wrong patch paths).

metadata key added to kwargs when security warnings exist is passed all the way through to sandbox.execute(). None of the SandboxProtocol.execute implementations accept a metadata keyword argument (the signature is code, language, limits, env, working_dir), so this will raise TypeError: execute() got an unexpected keyword argument 'metadata' on every code execution that triggers a security warning.

print() output
In e2b-code-interpreter>=1.0.0, standard output from print() is captured in execution.logs.stdout (a list of strings), not in execution.results. The results list holds rich display objects (matplotlib figures, DataFrames, etc.). Because the code only iterates execution.results, a plain print("Hello") will produce an empty stdout in the returned SandboxResult. The correct extraction should read from execution.logs.stdout and execution.logs.stderr.

There was a problem hiding this comment.
asyncio.get_event_loop() is deprecated in Python 3.10+ when called from within a running coroutine; asyncio.get_running_loop() is the correct replacement. This pattern appears throughout the file (stop, _execute_python_code, _execute_bash_command, write_file, read_file).

super().__init__() triggers all other mixin constructors after Agent is fully built
SandboxMixin.__init__ calls super().__init__(*args, **kwargs) which chains through the entire remaining MRO (UnifiedExecutionMixin, ToolExecutionMixin, etc.). Because this call is at the very end of Agent.__init__, all those constructors run after every self.* attribute has already been set. Before this PR, no super().__init__() was called from Agent.__init__ at all — it is worth verifying that none of the existing mixins have side effects when their __init__ runs at this late stage.

67-84: ⚡ Quick win
run_codeprovides only an async API — consider a sync wrapper.Per coding guidelines, "All I/O operations must have both sync and async variants" and core SDK should "wrap sync callers for async contexts without forcing conversions".
SandboxManageronly exposes async entry points, which forces non-async callers (e.g., the sync tool functions returned bySandboxMixin._get_code_execution_tools) to spin up their ownasyncio.run/loop handling. Arun_code_sync(with safe handling for already-running loops) would centralize that.As per coding guidelines: "All I/O operations must have both sync and async variants; never block the event loop with sync I/O in async context".

Inline comments:
In `@src/praisonai-agents/praisonaiagents/agent/agent.py`:
- Line 559: The constructor parameter "sandbox: Optional[Union[bool,
'SandboxConfig']]" uses a forward-ref string for SandboxConfig but SandboxConfig
is not imported in the TYPE_CHECKING block; add "SandboxConfig" to the
TYPE_CHECKING imports alongside MemoryConfig, ContextConfig, AutonomyConfig,
ApprovalConfig so static type checkers and linters see the symbol (update the
TYPE_CHECKING import list where other Config classes are imported and ensure any
references to SandboxConfig match the forward reference used in the Agent
__init__ signature).
In `@src/praisonai-agents/praisonaiagents/agent/sandbox_mixin.py`:
- Around line 223-226: The code in sandbox_mixin.py reads result.output which is
not part of the SandboxResult contract and can raise AttributeError; update the
handling in the execute path of the block using execute_code_sync (and the
similar block later in the same class) to return result.stdout if present,
otherwise fallback to result.stderr or an empty string (e.g., return
result.stdout or result.stderr or ""), and remove any use of result.output;
ensure you update both the first success branch around execute_code_sync and the
similar success branch further down so all uses conform to
stdout/stderr/error/success fields.
- Around line 239-241: The call to asyncio.run(self.run_shell_command(command))
in execute_shell_command can raise RuntimeError when an event loop is already
running; change it to detect a running loop and run the coroutine safely (mirror
the pattern used by execute_python_code/execute_code_sync): implement a
run_shell_command_sync (or reuse execute_code_sync pattern) that checks
asyncio.get_running_loop() and if a loop exists, schedule
self.run_shell_command(command) on a ThreadPoolExecutor (or use
asyncio.run_coroutine_threadsafe) otherwise call asyncio.run; update
execute_shell_command to call run_shell_command_sync instead of asyncio.run
directly.
In `@src/praisonai-agents/praisonaiagents/sandbox/manager.py`:
- Around line 280-300: The loop in manager.py that iterates over sandbox types
always sets "available": False even when the import and getattr succeed; change
the try branch to mark the package-as-present and, if possible, call a
class-level availability check (prefer an is_available classmethod on the
sandbox class, similar to how Docker/E2B are probed by attempting instantiation)
and set "available" to that result, otherwise set "available": True but add a
note (e.g., "verified": False or leave a comment) that the runtime could not be
fully verified without required args so callers can distinguish "package
installed but unverified" from "package missing"; update any is_available usage
to be a classmethod on Sandlock/SSHSandbox/ModalSandbox/DaytonaSandbox if
currently instance-based.
In `@src/praisonai-agents/praisonaiagents/sandbox/security.py`:
- Around line 297-299: The code in format_warnings and get_security_summary
assumes warning.severity is always one of {"critical","high","medium","low"}
which can raise KeyError for unexpected values; update the accumulation logic in
the loop that builds by_severity (and the similar loop at lines ~327-329) to
safely handle unknown severities by using dict.setdefault or dict.get with a
default list (e.g., by_severity.setdefault(warning.severity, []).append(warning)
or by_severity.get(warning.severity, by_severity["low"]).append(warning)),
ensuring unknown severities are placed into a sensible bucket (or a new bucket)
before appending so no KeyError occurs in format_warnings and
get_security_summary.
In `@src/praisonai/praisonai/sandbox/e2b.py`:
- Around line 258-269: In execute_file, avoid blocking the event loop by
replacing the synchronous open/read (the with open(...).read() that sets
variable code) with an asynchronous file read: either call await
asyncio.to_thread(lambda: Path(file_path).read_text()) or use an async file
library (e.g., aiofiles) to await reading the file content into code; ensure the
rest of execute_file uses the awaited code variable and keep error handling
intact around the async read.
- Around line 373-381: The cleanup() method currently does nothing and may leak
sandbox resources; update cleanup() to terminate the remote sandbox by calling
or delegating to the existing stop() logic (e.g., await self.stop() or invoke
the sandbox termination API on self._sandbox when present), ensure you only call
it if self._sandbox is truthy, properly await async teardown, and catch/log any
exceptions (use logger.warning or logger.exception) so failures are recorded;
reference the cleanup() and stop() methods and the self._sandbox attribute when
making the change.
- Around line 258-277: execute_file currently accepts an args parameter but
never forwards it; update execute_file to pass the args through to self.execute
for all branches (the calls to self.execute in execute_file should include
args=args), ensuring you handle the Optional[List[str]] value (pass None through
unchanged) and update the docstring if needed; reference the execute_file method
and the self.execute calls when making the change.
In `@test_sandbox_implementation.py`:
- Line 52: Remove the unnecessary f-string prefixes on constant print strings
(e.g., the print call that currently uses f"✅ Sandbox execution successful!" and
the other similar print at the later occurrence) — replace the f-prefixed
strings with plain string literals (remove the leading f) so they become "✅
Sandbox execution successful!" and the other constant string to avoid Ruff F541.
- Around line 30-113: Tests currently swallow exceptions and use prints instead
of assertions in test_sandbox_manager, test_security_checks, and
test_agent_integration; remove the try/except blocks that hide failures
(specifically the except blocks around manager.run_code in test_sandbox_manager
and around Agent creation/execution in test_agent_integration) so exceptions
propagate and tests fail, and replace print checks with assertions: assert
manager.get_available_types() contains the subprocess type from
SandboxConfig.subprocess(), assert the result from manager.run_code (via
manager.run_code or Agent.execute_code_sync) has expected
stdout/exit_code/duration properties, assert check_code_safety(safe_code)
returns empty and check_code_safety(dangerous_code) returns non-empty and that
format_warnings(warnings) returns a non-empty string; also assert
agent.has_sandbox is True and agent.sandbox_config.sandbox_type equals the
expected sandbox type.

Add SandboxConfig to TYPE_CHECKING imports for consistency with other Config classes.
The sandbox parameter uses a forward reference to SandboxConfig (as a string literal), which is valid and does not trigger linting errors. However, for consistency with similar Config classes (MemoryConfig, ContextConfig, AutonomyConfig, ApprovalConfig) and improved type checker support, SandboxConfig should be imported in the TYPE_CHECKING block.

Wrap asyncio.run() with event loop detection to prevent RuntimeError in async contexts.
The execute_shell_command tool at line 240 calls asyncio.run() directly without checking for an active event loop, unlike the adjacent execute_python_code tool which uses execute_code_sync() for proper handling. Since tools can be invoked from async agent flows, this will crash with RuntimeError. Apply the same pattern: create a run_shell_command_sync() method or detect the running loop with asyncio.get_running_loop() and use ThreadPoolExecutor to safely submit the async call if needed, following the guideline "One event loop per thread; never nest event loops; use asyncio.run() only at top level."

Loop reports available: False even when the import succeeds.
For sandlock/ssh/modal/daytona, the try block successfully imports the class but always sets "available": False, making the successful-import branch indistinguishable from the except branch. The comment says "Can't easily check without required args", yet Docker and E2B above do instantiate to check — the policy is inconsistent.
Suggested directions:
- If
is_availablerequires construction, mirror the Docker/E2B approach (and apply the fix from the previous comment to make it classmethod-style). - Otherwise, at minimum distinguish "package installed but unverified" from "package missing" so callers/UIs can give actionable guidance.

Convert these into assertion-based tests and fail on exceptions.
At Line 57 and Line 109, exceptions are swallowed and only logged; plus the test bodies rely on prints instead of assertions. This can let regressions pass undetected.

stop() raises inside __aexit__
stop() and cleanup() share a single try block, so an exception from stop() prevents cleanup() from running and leaves resources (processes, file handles, remote VMs) unreleased. The test test_context_manager_cleanup_error explicitly asserts that cleanup is called even after stop fails, confirming this is the intended contract. Each should be wrapped independently so cleanup always runs.

SandboxManager
Five tests — test_get_available_types, test_check_availability_subprocess, test_check_availability_docker, test_check_availability_not_available, and test_check_availability_unknown — call or patch SandboxManager._check_availability. This method does not exist in the SandboxManager class; the class exposes get_available_types() directly without a helper. All five tests will raise AttributeError (or the patch will silently no-op and assertions will fail).

test_create_sandbox_subprocess patches 'praisonai.sandbox.subprocess.SubprocessSandbox', but _create_subprocess_sandbox in manager.py imports via from praisonai.sandbox import SubprocessSandbox — resolved through the lazy __getattr__ in praisonai/sandbox/__init__.py. The patch never intercepts the live call, so the mock class is never used and the assertions will fail. The same issue affects the docker and e2b create-sandbox tests. The correct targets are 'praisonai.sandbox.DockerSandbox', etc.

Fix Needed: Add 3. Missing SandboxConfig Import (MEDIUM)Issue: TYPE_CHECKING block missing SandboxConfig import. Location: Fix Needed: Add SandboxConfig to TYPE_CHECKING imports. 4. DRY Violations FoundA. Duplicated Security Analysis (MEDIUM)Issue: Security checks run both regex and AST passes, creating duplicate warnings. B. Inconsistent Async/Sync Bridging (MEDIUM)Issue: Multiple patterns for async/sync bridging instead of using centralized utility. C. Availability Check Inconsistency (LOW)Issue: Some sandbox types always return 5. Architecture Compliance Issues✅ GOOD: Protocol-Driven Core
✅ GOOD: Backward Compatibility
❌ ISSUE: Missing Sync APIProblem: SandboxManager only provides async API, violating AGENTS.md principle:
Fix Needed: Add 6. Test Infrastructure IssuesIssue: Multiple test files found with overlapping coverage:
