Code Review
This pull request widens the type hints for several parameters in the Agent constructor, including context, autonomy, approval, and learn, to support strings and dictionaries. However, the review identifies multiple instances where the underlying implementation has not been updated to handle these new types, which could lead to runtime errors or features being silently disabled.

The widened type hint for approval includes Dict[str, Any], but the implementation (lines 1624-1659) does not convert a dictionary to an ApprovalConfig or backend instance. Instead, it assigns the dictionary directly to self._approval_backend in the else block at line 1654. This will cause runtime errors when the agent attempts to call backend methods on a dictionary object.

context/autonomy type hints now advertise unsupported runtime inputs.
Line 491 and Line 492 add str (and dict for context), but current runtime paths don’t normalize these forms (context_manager has no str/dict branch; _init_autonomy treats unsupported types as disabled). This creates a silent contract mismatch.

Pull request overview
This PR cherry-picks a commit that broadens Agent.__init__ configuration type hints to accept additional shorthand forms (e.g., str/dict/bool) for several consolidated feature parameters, aiming to make agent initialization more flexible and consistent with config-driven usage.
Changes:
- Widened type hints for
context,autonomy,output,execution,templates,caching,hooks,skills,approval, andlearn. - Expanded several parameters to allow
Dict[str, Any](and in some casesstr/bool) in the constructor signature.

The type hint now allows autonomy to be a str, but _init_autonomy() currently only handles True, dict, or AutonomyConfig and will silently disable autonomy for string inputs (e.g. documented autonomy="full_auto"). Either add explicit string handling (map presets like "full_auto"/"auto_edit"/"suggest" to an AutonomyConfig(level=...)) or remove str from the public signature to match behavior.

The signature now claims context supports str/dict, but context_manager initialization only recognizes True, ManagerConfig, ContextConfig, or a ContextManager-like object; str/dict fall through to the “unknown type, disable” branch. Either implement parsing for dict/str (e.g. dict -> ManagerConfig(**...) / ContextConfig.from_dict(...), and define what string means), or narrow the type hint so callers don’t get a false affordance.

templates is now typed as accepting str, but the resolver path doesn’t interpret non-path-like strings for TemplateConfig (it will generally return an empty TemplateConfig() which has no effect). If the intent is to accept a template preset name or file path, add explicit handling for those string forms; otherwise, remove str from the type hint to avoid misleading API docs/type-checkers.

approval is now typed to accept a Dict[str, Any], but the approval initialization logic only handles str presets, bool, or ApprovalConfig; a dict will fall into the “plain backend object” branch and likely fail later when treated as an ApprovalProtocol. Either support dict form explicitly (e.g. approval={"backend": ..., "all_tools": ..., "timeout": ...} -> ApprovalConfig(**...)) or drop Dict[...] from the type hint.

learn is now typed to accept a str, but __init__ currently passes unknown types through into memory["learn"], and Memory.learn only enables learning for bool, dict, or LearnConfig (other types return None). If you want a string shorthand (e.g. learn="agentic"), convert it into LearnConfig(mode=...); otherwise, remove str from the type hint to match runtime behavior.

output/execution type hints were widened to include bool and Dict[str, Any], but the Args: docstring section still only documents the str preset and *Config forms.

1. Autonomy preset strings ignored 🐞 Bug ≡ Correctness
Agent.__init__ now advertises autonomy can be a string, but _init_autonomy does not handle str values and will disable autonomy instead of applying presets like "full_auto". This breaks the public contract implied by AUTONOMY_PRESETS and AutonomyConfig docs.
Agent Prompt
### Issue description
`Agent.__init__` now type-hints `autonomy` as accepting `str`, but the runtime path (`_init_autonomy`) does not handle strings and silently disables autonomy when a string is passed (e.g. `"full_auto"`).
### Issue Context
The repo already defines `AUTONOMY_PRESETS` containing `"full_auto"`, and `AutonomyConfig` docs show `Agent(autonomy="full_auto")`, so string presets appear to be a supported user-facing API.
### Fix Focus Areas
- src/praisonai-agents/praisonaiagents/agent/agent.py[1314-1320]
- src/praisonai-agents/praisonaiagents/agent/agent.py[2137-2188]
- src/praisonai-agents/praisonaiagents/config/presets.py[298-307]
- src/praisonai-agents/praisonaiagents/config/param_resolver.py[600-610]
### Suggested fix
Either:
1) Implement `str` handling by resolving presets before `_init_autonomy` (e.g., use `AUTONOMY_PRESETS` / `resolve_autonomy()` to produce an `AutonomyConfig`), or
2) Revert the type hint to remove `str` if string presets are not intended to be supported.
Add/adjust a unit test for `Agent(autonomy="full_auto")` to assert `agent.autonomy_enabled is True` and that the configured level/mode matches the preset.

2. Context presets/dicts ignored 🐞 Bug ≡ Correctness
Agent.__init__ now advertises context can be a str or dict, but context_manager lazy-init only supports bool, ManagerConfig/ContextConfig, or a ContextManager instance; str/dict values fall into the unknown-type branch and disable context. This causes silent misconfiguration where context management never activates.
Agent Prompt
### Issue description
`Agent.__init__` now type-hints `context` as accepting `str` and `dict`, but the runtime context initialization only recognizes `True/False`, `ManagerConfig`/`ContextConfig`, or `ContextManager`. Passing a preset string or a dict results in context being silently disabled.
### Issue Context
The repo already provides `CONTEXT_PRESETS` and a canonical `resolve_context()` helper (supports string presets and dict-to-config conversion), but Agent stores the raw value and never resolves it.
### Fix Focus Areas
- src/praisonai-agents/praisonaiagents/agent/agent.py[1753-1761]
- src/praisonai-agents/praisonaiagents/agent/agent.py[1876-1964]
- src/praisonai-agents/praisonaiagents/config/presets.py[287-296]
- src/praisonai-agents/praisonaiagents/config/param_resolver.py[586-598]
### Suggested fix
Implement one of:
1) Resolve `context` in `__init__` before assigning `self._context_param`:
- `str` -> apply `CONTEXT_PRESETS` and build a `ContextConfig` (or ManagerConfig alias)
- `dict` -> `ContextConfig(**context)` with key validation
2) Alternatively, add handling for `str`/`dict` inside `context_manager` property.
Add tests for `Agent(context="summarize")` and `Agent(context={...})` ensuring `agent.context_manager` is not `None`.

3. Approval dict backend crash 🐞 Bug ≡ Correctness
Agent.__init__ now advertises approval can be a dict, but approval setup stores unknown types directly as _approval_backend, so a dict becomes the backend. Tool execution then calls backend.request_approval(...), which will raise AttributeError on a dict.
Agent Prompt
### Issue description
`Agent.__init__` now type-hints `approval` as accepting a `dict`, but the approval initialization code does not handle dicts and will store them as `_approval_backend`. Later, tool execution calls `backend.request_approval(...)`, which will crash with `AttributeError` for dict backends.
### Issue Context
There is an `ApprovalConfig` dataclass intended for structured configuration, and the runtime expects `_approval_backend` to implement `ApprovalProtocol` (`request_approval`).
### Fix Focus Areas
- src/praisonai-agents/praisonaiagents/agent/agent.py[1619-1658]
- src/praisonai-agents/praisonaiagents/agent/tool_execution.py[426-485]
- src/praisonai-agents/praisonaiagents/approval/protocols.py[55-83]
### Suggested fix
Add an explicit dict branch in Agent approval setup, e.g.:
- `elif isinstance(approval, dict): approval = ApprovalConfig(**approval)` (and optionally validate allowed keys)
Then let the existing `isinstance(approval, ApprovalConfig)` branch configure `_approval_backend`.
Alternatively, remove `Dict[str, Any]` from the type hint if dict configuration is not supported.
Add a unit test that passes `approval={"backend": SomeBackend(), "all_tools": True, "timeout": 10}` and verifies tool execution reaches the backend without crashing.
