Release v4.5.134

Enhance `bump_and_release.py` and `release.py` scripts to add specific
release files instead of all changes. Introduced a check for
uncommitted changes with informative error messages. This reduces the
risk of accidental changes during the release process.

         CRITICAL INSTRUCTION: If your task involves modifying codebase files to add a feature or fix a bug:
-        1. ALWAYS create a new git branch appropriately named (e.g. \`feature/issue-<number>\`).
-        2. MANDATORY: Before writing any code, you MUST carefully read "src/praisonai-agents/AGENTS.md" to understand this repository's extremely specific Architecture, Protocol-First design rules, and Agent-Centric Philosophy.
-        3. Make your necessary code changes honoring the rules in AGENTS.md.
-        4. Commit your changes and push the branch to the remote repository.
-        5. Use the GitHub CLI (\`gh pr create --title "..." --body "Fixes #<number>"\`) to open a Pull Request containing your work.

+        STEP 0 — SETUP GIT IDENTITY:
+        git config user.name "MervinPraison"
+        git config user.email "[email protected]"
+
+        STEP 1 — READ GUIDELINES:
+        MANDATORY: Before writing any code, you MUST carefully read "src/praisonai-agents/AGENTS.md" to understand this repository's extremely specific Architecture, Protocol-First design rules, and Agent-Centric Philosophy.
+
+        STEP 2 — ARCHITECTURE VALIDATION & ROUTING (MANDATORY before writing code):
+        Before implementing anything, answer these questions:
+        - CORE vs WRAPPER vs TOOLS ROUTING:
+          1. Core SDK (praisonaiagents/): Only core protocols, base classes, decorators. No heavy implementations.
+          2. Wrapper (praisonai/): CLI, heavy implementations, optional dependencies.
+          3. Tools (PraisonAI-Tools): Specific integrations, external tools (e.g. SurrealDB, Slack), and community extensions MUST go to the `MervinPraison/PraisonAI-Tools` repository. If the feature is a tool, clone `https://github.com/MervinPraison/PraisonAI-Tools`, implement it there, and create the PR using `gh pr create -R MervinPraison/PraisonAI-Tools`.
+        - Does it duplicate existing functionality? Check if Agent already supports this via existing params (reflection, planning, tools, hooks, memory).
+        - Does it inherit from Agent properly? New agent types MUST inherit Agent, not wrap it with composition.
+        - Does it add new dependencies? Only optional deps allowed, must be lazy-imported.
+        - Will agent.py grow larger? If the change adds >50 lines to agent.py, find a way to extract instead.
+        - Is there a name collision with existing exports in __init__.py?
+        If ANY of these conceptual checks fail (excluding routing), add a comment to the issue explaining why and close it. Do NOT create a PR.
+
+        STEP 3 — IMPLEMENT:
+        - Create a new git branch appropriately named (e.g. \`feature/issue-<number>\`)
+        - Follow protocol-driven design: protocols in core SDK, heavy implementations in wrapper
+        - Keep changes small and backward-compatible
+
+        STEP 4 — TEST:
+        - Run: cd src/praisonai-agents && PYTHONPATH=. python -m pytest tests/ -x -q --timeout=30
+        - Ensure no regressions
+
+        STEP 5 — CREATE PR:
+        - Commit with descriptive message, push the branch
+        - Use the GitHub CLI (\`gh pr create --title "..." --body "Fixes #<number>"\`) to open a Pull Request
+        CRITICAL: You MUST create the PR automatically using \`gh pr create\`. Do NOT just provide a link.

-            git config user.email "[email protected]"
+            STEP 0 — SETUP GIT IDENTITY & AUTH (GLOBAL — required for all repos):

+            git config --global user.email "[email protected]"
+            gh auth setup-git
+
 
             STEP 1 — READ GUIDELINES:
             Read AGENTS.md to understand the architecture rules.
 
-            STEP 2 — ARCHITECTURE VALIDATION (MANDATORY before writing code):
+            STEP 2 — ARCHITECTURE VALIDATION & ROUTING (MANDATORY before writing code):
             Before implementing anything, answer these questions:
-            - Does this add heavy implementations to the core SDK (praisonaiagents)? If YES → move it to the wrapper (praisonai) or make it a plugin.
+            - CORE vs WRAPPER vs TOOLS vs DOCS vs PLUGINS ROUTING:
+              1. Core SDK (praisonaiagents/): Only core protocols, base classes, decorators. No heavy implementations.
+              2. Wrapper (praisonai/): CLI, heavy implementations, optional dependencies.
+              3. Tools (PraisonAI-Tools): Capabilities Agents actively call during execution (e.g. SurrealDB tool, Slack tool).
+              4. Documentation (PraisonAIDocs): Documentation pages, guides, API references.
+              5. Plugins (PraisonAI-Plugins): Framework lifecycle extensions replacing systemic behavior (e.g. tracing, logging, metrics, hooks, guardrails).
+              For items routed to an EXTERNAL repository (Tools, Docs, Plugins), follow STEP 3-ALT below.
             - Does it duplicate existing functionality? Check if Agent already supports this via existing params (reflection, planning, tools, hooks, memory).
             - Does it inherit from Agent properly? New agent types MUST inherit Agent, not wrap it with composition.
             - Does it add new dependencies? Only optional deps allowed, must be lazy-imported.
             - Will agent.py grow larger? If the change adds >50 lines to agent.py, find a way to extract instead.
             - Is there a name collision with existing exports in __init__.py?
-            If ANY of these checks fail, add a comment to the issue explaining why and close it. Do NOT create a PR.
+            If ANY of these conceptual checks fail (excluding routing), add a comment to the issue explaining why and close it. Do NOT create a PR.
 
-            STEP 3 — IMPLEMENT:
+            STEP 3 — IMPLEMENT (for changes in THIS repo — PraisonAI):
             - Create a fix branch and implement a minimal, focused fix
             - Follow protocol-driven design: protocols in core SDK, heavy implementations in wrapper
             - Keep changes small and backward-compatible
 
+            STEP 3-ALT — IMPLEMENT IN EXTERNAL REPO (for PraisonAI-Tools, PraisonAIDocs, PraisonAI-Plugins):
+            When work must happen in a different repository, follow these steps EXACTLY. Do NOT attempt to use `cd`, as directory state is not preserved. Use `git -C` for all commands.
+            a) Clone the repository:
+               gh repo clone MervinPraison/<REPO_NAME> /tmp/<REPO_NAME>
+            b) Copy GitHub authentication from the main repository so push works seamlessly:
+               git -C /tmp/<REPO_NAME> config http."https://github.com/".extraheader "$(git config --get http."https://github.com/".extraheader)"
+            c) Create a feature branch (NEVER commit to main):
+               git -C /tmp/<REPO_NAME> checkout -b claude/issue-$ISSUE_NUMBER-$(date +%Y%m%d)
+            d) Make your changes using absolute paths (e.g. edit /tmp/<REPO_NAME>/docs.json)
+            e) Commit:
+               git -C /tmp/<REPO_NAME> add -A
+               git -C /tmp/<REPO_NAME> commit -m "feat: <description> (fixes #$ISSUE_NUMBER)"
+            f) Push the branch:
+               git -C /tmp/<REPO_NAME> push origin claude/issue-$ISSUE_NUMBER-$(date +%Y%m%d)
+            g) Create PR in the EXTERNAL repo:
+               gh pr create -R MervinPraison/<REPO_NAME> --head claude/issue-$ISSUE_NUMBER-$(date +%Y%m%d) --title "feat: <title>" --body "Fixes MervinPraison/PraisonAI#$ISSUE_NUMBER
+
+               <body>"
+

-            - Run: cd src/praisonai-agents && PYTHONPATH=. python -m pytest tests/ -x -q --timeout=30
+            - For SDK changes: cd src/praisonai-agents && PYTHONPATH=. python -m pytest tests/ -x -q --timeout=30
+            - For docs changes: verify files exist and are valid markdown/MDX
             - Ensure no regressions
 
             STEP 5 — CREATE PR:
             - Commit with descriptive message, push, and create PR using `gh pr create`
-            CRITICAL: You MUST create the PR automatically using `gh pr create`. Do NOT just provide a link.
+            - For external repos, use `gh pr create -R MervinPraison/<REPO_NAME>`
+            CRITICAL: You MUST create the PR automatically using `gh pr create`. Do NOT just provide a link or say "manual push required".
+            NOTE: If you worked on an external repo, the wrapper action will report "No commits" for the main repo at the end. This is expected, do not worry about it.

+# PraisonAI PR Reviewer Integration Guide
+
+This guide provides step-by-step instructions for integrating PraisonAI as an automated PR reviewer in your GitHub CI/CD pipeline.
+
+## Overview
+
+PraisonAI PR Reviewer implements a **Zero-Code, Multi-Agent PR Review System** that deploys specialized agents to analyze pull requests from multiple perspectives:
+
+- 🔐 **Security Reviewer**: Identifies vulnerabilities and security issues
+- ⚡ **Performance Reviewer**: Analyzes for bottlenecks and inefficiencies  
+- 📋 **Maintainability Reviewer**: Evaluates code quality and best practices
+- 👨‍💼 **Lead Reviewer**: Synthesizes feedback and posts comprehensive reviews
+
+## Architecture
+
+This integration follows PraisonAI's **Agent-Centric** and **Protocol-Driven Core** design principles:
+
+```
+GitHub PR → @praisonai trigger → Multi-Agent Workflow → Comprehensive Review
+```
+
+The solution leverages:
+- **GitHub Actions** for CI/CD orchestration
+- **PraisonAI CLI** for agent execution
+- **YAML Configuration** for agent team definition
+- **GitHub CLI** for PR interaction
+
+## Prerequisites
+
+1. **Repository Setup**:
+   - GitHub repository with Actions enabled
+   - Required secrets configured (see [Secrets Configuration](#secrets-configuration))
+
+2. **PraisonAI Installation**:
+   - The workflow automatically installs PraisonAI via `pip install praisonai`
+   - No additional dependencies required
+
+3. **GitHub App/Token**:
+   - GitHub App with required permissions OR
+   - Personal Access Token with `repo` and `pull_requests` permissions
+
+## Installation Steps
+
+### Step 1: Copy Agent Configuration
+
+The agent configuration is already provided at:
+```
+.github/praisonai-reviewer.yaml
+```
+
+This file defines the multi-agent team and their specific responsibilities.
+
+### Step 2: Create GitHub Workflow
+
+**IMPORTANT**: Due to GitHub App permissions, the workflow file must be manually created.
+
+1. Copy the template from:
+   ```
+   examples/yaml/praisonai-pr-review.yml.template
+   ```
+
+2. Save it as:
+   ```
+   .github/workflows/praisonai-pr-review.yml
+   ```
+
+### Step 3: Configure Secrets
+
+Add the following secrets to your repository (`Settings > Secrets and variables > Actions`):
+
+| Secret | Description | Required |
+|--------|-------------|----------|
+| `PRAISONAI_APP_ID` | GitHub App ID | Yes (if using GitHub App) |
+| `PRAISONAI_APP_PRIVATE_KEY` | GitHub App private key | Yes (if using GitHub App) |
+| `OPENAI_API_KEY` | OpenAI API key for LLM access | Yes |
+
+**Alternative**: Use `GH_TOKEN` instead of GitHub App if you prefer PAT authentication.
+
+### Step 4: Update Review Chain (Optional)
+
+The review chain documentation has been updated to include PraisonAI:
+```
+CodeRabbit/Qodo → Gemini/PraisonAI (parallel) → Copilot → Claude (final)
+```
+
+This ensures PraisonAI integrates seamlessly with existing review workflows.
+
+## Usage
+
+### Manual Trigger
+
+1. **Workflow Dispatch**: 
+   - Go to `Actions > PraisonAI PR Review > Run workflow`
+   - Enter the PR number to review
+
+### Automatic Trigger
+
+1. **Comment Trigger**:
+   - Comment `@praisonai` on any pull request
+   - Only repository owners, members, and collaborators can trigger
+
+2. **With Instructions**:
+   - `@praisonai focus on security vulnerabilities`
+   - `@praisonai check performance and memory usage`
+   - `@praisonai review for maintainability issues`
+
+## Expected Output
+
+When triggered, PraisonAI will post a comprehensive review with this structure:
+
+```markdown
+## 📋 Review Summary
+[Brief overview and assessment]
+
+## 🔍 General Feedback  
+[Overall patterns and observations]
+
+## 🎯 Specific Feedback
+### 🔴 Critical
+[Security vulnerabilities, breaking changes, major bugs]
+
+### 🟡 High 
+[Performance issues, design flaws, significant bugs]
+
+### 🟢 Medium
+[Code quality improvements, minor optimizations]
+
+### 🔵 Low
+[Documentation, naming suggestions, minor refactoring]
+
+## ✅ Highlights
+[Positive aspects worth mentioning]
+
+---
+*Review completed by PraisonAI Multi-Agent Team*
+```
+
+## Integration with Existing Workflows
+
+PraisonAI integrates seamlessly with the existing review chain:
+
+1. **Parallel Execution**: Runs alongside Gemini for faster reviews
+2. **No Conflicts**: Uses unique trigger (`@praisonai`) to avoid interference
+3. **Complementary Analysis**: Provides different perspectives from other tools
+4. **Chain Continuation**: Claude final review incorporates PraisonAI feedback
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Authentication Errors**:
+   - Verify `PRAISONAI_APP_ID` and `PRAISONAI_APP_PRIVATE_KEY` secrets are correctly set
+   - Ensure GitHub App has required permissions
+
+2. **PraisonAI Installation Fails**:
+   - Check if Python setup step completed successfully
+   - Verify internet connectivity for pip installation
+
+3. **Agent Execution Fails**:
+   - Check `OPENAI_API_KEY` secret is valid
+   - Verify agent configuration YAML syntax
+
+4. **Permission Denied**:
+   - Ensure triggering user has required repository permissions
+   - Check workflow file permissions configuration
+
+### Debug Steps
+
+1. **Check Workflow Logs**:
+   - Go to `Actions > PraisonAI PR Review`
+   - Click on failed run to see detailed logs
+
+2. **Validate Configuration**:
+   - Ensure `.github/praisonai-reviewer.yaml` syntax is valid
+   - Test agent configuration locally if possible
+
+3. **Test Manual Trigger**:
+   - Use workflow dispatch to isolate comment trigger issues
+
+## Advanced Configuration
+
+### Custom Agent Teams
+
+Modify `.github/praisonai-reviewer.yaml` to:
+- Add specialized agents (e.g., Architecture Reviewer)
+- Adjust agent responsibilities
+- Customize review output format
+
+### Integration with External Tools
+
+Extend agents to integrate with:
+- Code quality tools (SonarQube, CodeClimate)
+- Security scanners (Snyk, SAST tools)  
+- Performance profilers
+
+### Environment-Specific Reviews
+
+Configure different agent teams for:
+- Backend vs Frontend changes
+- Different programming languages
+- Specific project domains
+
+## Performance Considerations
+
+- **Execution Time**: Typically 3-5 minutes for comprehensive review
+- **Rate Limits**: Respects GitHub API and OpenAI rate limits
+- **Cost**: Uses OpenAI API - monitor usage for cost control
+- **Parallel Execution**: Agents run concurrently for efficiency
+
+## Security
+
+- **Secret Handling**: All credentials stored securely in GitHub Secrets
+- **Permissions**: Minimal required permissions for workflow execution
+- **Code Access**: Review-only access, no code modification capabilities
+- **Audit Trail**: All reviews logged in GitHub Actions logs
+
+## Contributing
+
+To improve the PraisonAI PR Reviewer:
+
+1. **Agent Enhancement**: Improve agent prompts and capabilities
+2. **Workflow Optimization**: Enhance GitHub Actions workflow
+3. **Documentation**: Update guides and troubleshooting info
+4. **Integration**: Add support for additional tools and platforms

 CodeRabbit and Qodo skip `github-actions[bot]` authored PRs by default. The `bot-pr-trigger-reviews` job in `auto-pr-comment.yml` explicitly triggers them via comments.
 
+## PraisonAI Integration
+
+PraisonAI provides multi-agent PR review capabilities through the native PraisonAI agent framework. When triggered with `@praisonai`, it deploys a team of specialized agents:
+
+- **Security Reviewer**: Analyzes for vulnerabilities, authentication issues, and unsafe code practices
+- **Performance Reviewer**: Identifies bottlenecks, inefficient algorithms, and resource usage issues  
+- **Maintainability Reviewer**: Evaluates code quality, documentation, and adherence to best practices
+- **Lead Reviewer**: Synthesizes feedback and posts comprehensive review comments
+
+The workflow uses the agent configuration at `.github/praisonai-reviewer.yaml` and leverages the `praisonai` CLI for execution.
+
 ## Key rules
 
 - **Copilot ignores bot comments.** All `@copilot` mentions MUST use `GH_TOKEN` (not `GITHUB_TOKEN`) so comments post as `MervinPraison`.

+Memory Adapter Factory Functions
+
+Provides factory functions for heavy memory adapters that replace hardcoded imports
+in memory/memory.py. These enable lazy loading of heavy dependencies while maintaining
+the protocol-driven architecture.
+
+Each factory function:
+1. Lazy imports the required dependencies 
+2. Creates and returns an adapter instance that implements MemoryProtocol
+3. Raises clear ImportError with installation instructions if dependencies missing
+
+This approach follows the protocol-driven core principle by moving heavy implementations
+out of the core Memory class while preserving backward compatibility.
