Fixes #1856

Summary

This PR addresses three concrete wrapper layer violations of PraisonAI's core principles (DRY, protocol-driven, minimal API, multi-agent + async safe):

1. Duplicate arun() method definitions

Problem: Both FrameworkAdapter Protocol and BaseFrameworkAdapter class defined arun() twice, creating dead code and maintenance confusion.

Solution:

  • Removed duplicate Protocol declaration (lines 95-121 in base.py)
  • Removed first base implementation (lines 160-181 in base.py)
  • Kept single authoritative implementation with improved documentation

2. CLI tool resolution bypass

Problem: CLI's _load_tools() bypassed the unified ToolResolver, directly accessing TOOL_MAPPINGS, causing CLI/YAML/Python inconsistency.

Solution:

  • Updated CLI to use ToolResolver.resolve(tool_name, instantiate=True)
  • Now CLI, YAML, and Python all use the same 5-layer resolution chain
  • Maintains same instantiation semantics across all interfaces

3. Async scheduler divergence

Problem:

  • AsyncAgentScheduler had explicit TODO comments admitting missing daemon state updates
  • ScheduleParser existed in both base.py and shared.py (duplication)

Solution:

  • Created shared _BaseAgentScheduler class for common logic
  • Implemented missing _update_state_if_daemon() calls in async scheduler
  • Consolidated ScheduleParser to single source in shared.py
  • Both schedulers now use shared _build_stats() method

Verification

  • All files compile without syntax errors
  • Basic import and inheritance tests pass
  • Maintains backward compatibility
  • Follows protocol-driven design principles

Changes

  • framework_adapters/base.py: Remove duplicate arun() definitions
  • cli/main.py: Use ToolResolver instead of direct TOOL_MAPPINGS access
  • scheduler/_base_scheduler.py: New shared base class (created)
  • scheduler/base.py: Remove duplicate ScheduleParser, import from shared
  • scheduler/agent_scheduler.py: Inherit from base, use shared methods
  • scheduler/async_agent_scheduler.py: Inherit from base, implement missing daemon updates

πŸ“ Walkthrough

Walkthrough

This PR consolidates scheduler code by introducing a shared base class for common stats building and daemon state persistence, unifies CLI tool loading to use the ToolResolver, and enhances the framework adapter protocol with a cleanup hook and clarified async documentation. Changes preserve public APIs while eliminating sync/async scheduler duplication.

Changes

Scheduler Consolidation and Daemon State Updates

Layer / File(s) Summary
Shared base scheduler foundation with stats and daemon state
src/praisonai/praisonai/scheduler/_base_scheduler.py
New _BaseAgentScheduler class provides _build_stats() to compute execution runtime, success rates, budget remaining, and cost-per-execution metrics, and _update_state_if_daemon() to scan ~/.praisonai/schedulers for JSON state files, match entries by current PID, update execution counts and cost, and persist changes with exception safety.
Schedule parser unified source
src/praisonai/praisonai/scheduler/base.py
ScheduleParser moved from local class definition to import from .shared, establishing a single canonical source and eliminating duplicate implementation.
Sync scheduler inherits shared base
src/praisonai/praisonai/scheduler/agent_scheduler.py
AgentScheduler now inherits from _BaseAgentScheduler and delegates stats dictionary construction in get_stats() to the shared _build_stats() helper.
Async scheduler inherits shared base and calls daemon state update
src/praisonai/praisonai/scheduler/async_agent_scheduler.py
AsyncAgentScheduler inherits from _BaseAgentScheduler, uses shared _build_stats() in get_stats_async(), and calls _update_state_if_daemon() on both execution success and failure paths in _execute_with_retry().

CLI Tool Resolution and Framework Adapter Enhancements

Layer / File(s) Summary
CLI unified tool loading via ToolResolver
src/praisonai/praisonai/cli/main.py
_load_tools() now resolves comma-separated tool names using ToolResolver.resolve(..., instantiate=True) instead of legacy praisonaiagents.tools.TOOL_MAPPINGS, unifying CLI tool loading with YAML and Python code paths.
Framework adapter cleanup hook and async documentation
src/praisonai/praisonai/framework_adapters/base.py
Protocol FrameworkAdapter gains a cleanup() method declaration; BaseFrameworkAdapter.arun() docstring is refined to explicitly document thread-pool offload behavior for sync-only adapters (e.g., crewai/autogen v0.2).

Greptile Summary

This PR refactors three wrapper-layer concerns in PraisonAI: removing duplicate arun() declarations from the FrameworkAdapter protocol and BaseFrameworkAdapter, routing CLI tool loading through the shared ToolResolver instead of accessing TOOL_MAPPINGS directly, and consolidating sync/async scheduler logic into a new _BaseAgentScheduler base class that also backfills the missing _update_state_if_daemon() calls in the async scheduler.

  • framework_adapters/base.py: One redundant arun() stripped from both the Protocol stub and BaseFrameworkAdapter; the surviving implementation receives updated documentation and a cleanup() no-op default.
  • cli/main.py: _load_tools() now delegates name resolution to ToolResolver.resolve(instantiate=True), giving CLI the same 5-layer lookup chain used by YAML and Python paths.
  • scheduler/: New _BaseAgentScheduler provides _build_stats() and _update_state_if_daemon(); AgentScheduler and AsyncAgentScheduler inherit them; the previously TODO-blocked daemon-state updates in the async scheduler are wired via asyncio.to_thread, and AsyncAgentScheduler.__init__ now properly initialises self._start_time = None.

Confidence Score: 5/5

Safe to merge; all three changes are straightforward consolidations with no altered runtime paths that could cause data loss or crashes.

The duplicate-method removals are mechanical and confirmed correct by reading the surviving implementations. The CLI tool-resolver switch is additive (more resolution layers, not fewer), and the async daemon-state fix properly offloads blocking I/O via asyncio.to_thread. The _start_time initialisation gap called out in the previous review is resolved. The only new finding is a minor precision change on runtime_seconds in the consolidated stats builder, which does not affect correctness.

No files require special attention; the _base_scheduler.py rounding change on runtime_seconds is worth a quick check if any downstream code formats or compares that field to a fixed precision.

Important Files Changed

Filename Overview
src/praisonai/praisonai/scheduler/_base_scheduler.py New shared base class; correctly uses is not None for remaining_budget guard; runtime_seconds is now unrounded (was round(runtime, 1) in AgentScheduler), a minor schema change for existing callers.
src/praisonai/praisonai/scheduler/async_agent_scheduler.py Fixes missing _start_time init and previously TODO'd _update_state_if_daemon() calls via asyncio.to_thread; get_stats_sync() inline dict still diverges from the new _build_stats() schema (pre-existing, noted in previous review).
src/praisonai/praisonai/scheduler/agent_scheduler.py Cleanly delegates get_stats() and _update_state_if_daemon() to the shared base; logic is functionally unchanged; remaining_budget is now added to the stats dict (was absent before).
src/praisonai/praisonai/scheduler/base.py Duplicate ScheduleParser class removed; re-exported from shared.py as the single source of truth; no functional changes to remaining classes.
src/praisonai/praisonai/cli/main.py Tool resolution correctly switched to ToolResolver; empty-string filtering added; error handling improved; behavioral change is intentional and consistent with YAML/Python paths.
src/praisonai/praisonai/framework_adapters/base.py Removes two redundant arun() stubs cleanly; the single surviving implementation is correct; cleanup() default no-op added to BaseFrameworkAdapter.

Initialize _start_time before delegating to _build_stats().

get_stats_async() now depends on _build_stats(), which reads self._start_time, but _start_time is never initialized in AsyncAgentScheduler. This can raise AttributeError on stats reads.

Do not run daemon-state sync I/O directly on the event loop.

_update_state_if_daemon() performs blocking filesystem/JSON operations. Calling it directly in async retry paths can stall the loop and delay other async work.

Final Architecture Review and Fixes βœ…

Acting as the final architecture reviewer for PR #1857. Here's my systematic analysis:

Phase 1: Architecture Review per AGENTS.md

  • Read AGENTS.md guidelines
  • Check protocol-driven design compliance βœ… PASSES - Changes are in wrapper layer, proper inheritance from shared base
  • Verify backward compatibility βœ… PASSES - No breaking changes to public APIs, maintains same interface signatures
  • Check for performance regressions βœ… PASSES - Actually reduces duplication and import overhead

Phase 2: Fixed Critical Issues from Other Reviewers

  • CRITICAL: Fix AsyncAgentScheduler missing _start_time initialization

    • βœ… FIXED: Added self._start_time: Optional[datetime] = None in __init__
    • βœ… FIXED: Set self._start_time = datetime.now() when scheduler starts
  • MAJOR: Fix blocking I/O in async context (_update_state_if_daemon())

    • βœ… FIXED: Wrapped calls with await asyncio.to_thread(self._update_state_if_daemon) in both success and failure paths
  • MINOR: Fix max_cost=0.0 handling in _base_scheduler.py

    • βœ… FIXED: Changed if self.max_cost to if self.max_cost is not None to properly handle zero budgets

Phase 3: Architecture Compliance Analysis

Protocol-Driven Design βœ…

  • Core SDK (praisonaiagents/) contains only protocols and base classes
  • Wrapper layer (praisonai/) contains heavy implementations (schedulers, CLI, framework adapters)
  • Changes follow proper layering: shared base class extracts common logic without polluting core SDK

DRY Principle βœ…

  • Removes duplicate arun() method definitions in framework adapter (Protocol + base class)
  • Consolidates ScheduleParser to single source in shared.py
  • Creates _BaseAgentScheduler to eliminate duplicate stats/daemon logic between sync/async schedulers

Multi-Agent + Async Safe βœ…

  • Async scheduler properly uses asyncio.to_thread() for blocking I/O
  • No shared mutable global state
  • Each scheduler instance owns its state and primitives

Performance βœ…

  • No hot-path regressions
  • CLI tool loading now uses unified ToolResolver (consistent with YAML/Python paths)
  • Lazy loading patterns preserved

Files Modified in This Review:

  • src/praisonai/praisonai/scheduler/async_agent_scheduler.py - Fixed critical _start_time initialization and async I/O
  • src/praisonai/praisonai/scheduler/_base_scheduler.py - Fixed zero budget handling

What Was Not Modified (Correctly Addressed in Original PR):

  • CLI tool resolution unification - βœ… Already properly implemented using ToolResolver
  • Framework adapter duplication removal - βœ… Clean protocol-driven consolidation
  • Schedule parser deduplication - βœ… Single source in shared.py
  • Sync scheduler inheritance - βœ… Properly inherits from _BaseAgentScheduler

Final Verdict: APPROVED βœ…

This PR successfully addresses the three concrete wrapper layer violations outlined in issue #1856:

  1. βœ… Duplicate arun() removal - Clean consolidation with single authoritative implementation
  2. βœ… CLI tool resolution unification - Now uses ToolResolver like YAML/Python paths
  3. βœ… Async scheduler consolidation - Shared base class eliminates duplication, fixes missing daemon state updates

All critical bugs identified by other reviewers have been fixed and tested.

The changes are minimal, focused, and follow PraisonAI's architecture principles. Ready for merge.


| Branch: claude/issue-1856-20260605-0814

…, zero budget handling

- Initialize _start_time in AsyncAgentScheduler.__init__ to prevent AttributeError in get_stats()
- Set _start_time when scheduler starts to track runtime properly
- Wrap _update_state_if_daemon() calls with asyncio.to_thread() to avoid blocking event loop
- Fix max_cost=0.0 handling by using 'is not None' instead of truthiness check

Fixes critical issues identified in PR review by CodeRabbit, Greptile, and Copilot.
