Release v4.6.7

* fix: complete n8n integration minor gaps and enhancements (fixes #1402)

- Fix Typer test assertion for modern API (handles both registered_commands list and legacy commands dict)
- Add loop: → splitInBatches mapping in YAMLToN8nConverter with proper node creation
- Add n8n module documentation in main __init__.py (direct import recommended)
- Create comprehensive N8N_INTEGRATION_TEST_GUIDE.md for GitHub Actions setup
- All 18 tests now pass with enhanced CLI command detection logic

* fix: address reviewer feedback on n8n integration

- Update n8n documentation to use API key authentication instead of deprecated basic auth
- Fix N8nClient constructor signature in examples (use api_key parameter)
- Remove n8n from __all__ to enforce direct import pattern
- Consolidate CI job setup in documentation to avoid duplication

+description: Comprehensive analysis workflow that produces a detailed GitHub issue — combines deep codebase analysis with issue creation for implementation-ready tickets
+---
+
+# Analysis → GitHub Issue Workflow
+
+Deep Analysis → Gap Analysis → Critical Review → Plan → Create GitHub Issue.
+
+> **When to use this:** You need to analyze a feature, integration, or system deeply and produce a GitHub issue that another agent/developer can implement immediately without asking follow-up questions.
+> **When NOT to use this:** Use `/analysis` for analysis-only (no issue). Use `/local-fix` if you're implementing yourself.
+
+---
+
+## PRINCIPLES (apply throughout)
+
+- **Agent-centric**: Agents, workflows, sessions, tools, memory, multi-agent safety.
+- **Protocol-driven core**: praisonaiagents = lightweight, protocol-first (protocols/hooks/adapters only).
+- **DRY**: identify reuse; avoid duplication.
+- **No perf impact**: preserve import-time and hot-path; heavy deps optional + lazy.
+- **Async-safe + multi-agent safe** by default.
+- **Easy for non-developers**: "Few lines of code to do the task!"
+
+---
+
+## CANONICAL PATHS
+
+```
+Core SDK:    /Users/praison/praisonai-package/src/praisonai-agents (praisonaiagents)
+Wrapper:     /Users/praison/praisonai-package/src/praisonai (praisonai)
+Tools:       /Users/praison/PraisonAI-tools
+Docs:        /Users/praison/PraisonAIDocs
+TypeScript:  /Users/praison/praisonai-package/src/praisonai-ts
+Extension:   tools/base.py, tools/decorator.py, db/*
+```
+
+---
+
+## Phase 1 — Acceptance Criteria
+
+Translate the request into testable criteria:
+- API expectations (classes, methods, signatures)
+- CLI expectations (commands, flags, help text)
+- Documentation expectations (pages, examples)
+- Test expectations (unit, integration, smoke, real agentic)
+- Performance constraints (import time, hot-path)
+
+---
+
+## Phase 2 — External Research (if applicable)
+
+### 2a. Read official sources
+
+If analyzing an external integration, research from primary sources:
+
+```bash
+# Use read_url_content tool for:
+# - Official site / announcement pages
+# - GitHub README and docs
+# - Framework documentation
+# - Third-party write-ups
+```
+
+**Capture:**
+- What is it? Purpose and design goals
+- Key terminology and concepts
+- Architecture overview
+- Current ecosystem state
+- References list (all URLs)
+
+### 2b. Clone & analyze external codebase (if applicable)
+
+```bash
+git clone <repo-url> ~/<repo-name> --depth=1
+ls -la ~/<repo-name>/
+```
+
+Key files to read:
+- `AGENTS.md` / `README.md` — architecture overview
+- Base class files (abstract methods, signatures)
+- Factory / registry files (registration pattern)
+- Model/config files (data structures)
+- Example implementations (minimal + full-featured)
+- `pyproject.toml` / `package.json` — dependencies
+
+---
+
+## Phase 3 — PraisonAI Codebase Inventory
+
+### 3a. Inventory with evidence
+
+Go through ALL relevant files, understand current logic end-to-end.
+
+```bash
+# Core SDK
+ls /Users/praison/praisonai-package/src/praisonai-agents/praisonaiagents/
+grep -r "class.*Protocol" praisonaiagents/ --include="*.py" | wc -l
+
+# Wrapper
+ls /Users/praison/praisonai-package/src/praisonai/praisonai/
+ls /Users/praison/praisonai-package/src/praisonai/praisonai/cli/commands/
+
+# TypeScript
+ls /Users/praison/praisonai-package/src/praisonai-ts/src/
+```
+
+**Document:**
+- Public APIs: modules/classes/functions and exports
+- Protocols/adapters/hooks and extension points
+- CLI commands, options, help text
+- Integrations (db/observability/tools)
+- Tests (unit/integration), fixtures, CI config
+- Docs (Mintlify), examples, recipes
+
+Provide: **file paths + key symbols + grep counts + entry points**.
+
+### 3b. Identify DRY opportunities
+
+- Existing abstractions that can be reused
+- Duplicated code that should be consolidated
+- Existing protocols before creating new ones
+
+---
+
+## Phase 4 — Detailed Analysis
+
+### 4a. Architecture and behavior
+
+- Control flow and data flow
+- Concurrency model (sync/async)
+- Multi-agent interactions
+- Dependency boundaries (core/wrapper/tools)
+- Failure modes and error handling
+
+### 4b. Invariants check
+
+Verify these are preserved:
+- [ ] Protocol-driven core (no heavy impls in praisonaiagents)
+- [ ] Lazy imports (optional deps never at module level)
+- [ ] Backward compatible (public API changes need deprecation)
+- [ ] Safe defaults (new features opt-in)
+
+---
+
+## Phase 5 — Gap Analysis
+
+Compare acceptance criteria vs current state.
+
+### Checklist
+
+| Area | Current State | Gap | Severity | Impact | Placement |
+|------|---------------|-----|----------|--------|-----------|
+| Core SDK | | | | | |
+| Wrapper | | | | | |
+| Tools/plugins | | | | | |
+| CLI | | | | | |
+| Docs | | | | | |
+| Tests | | | | | |
+| Exports | | | | | |
+| Perf | | | | | |
+| Multi-agent + async | | | | | |
+
+### Gap severity levels
+- **Critical**: Blocks functionality
+- **High**: Significant limitation
+- **Medium**: Missing feature
+- **Low**: Nice-to-have
+
+---
+
+## Phase 6 — Critical Review
+
+### 6a. Risks and footguns
+
+- API ambiguity or edge cases
+- Backward compatibility concerns
+- Coupling violations
+- Performance regressions
+- Concurrency hazards
+- Misuse risks
+- Operational concerns
+
+### 6b. Mitigation strategies
+
+For each risk, document:
+- "Safe by default" recommendation
+- Explicit opt-in for dangerous behavior
+- Documentation warnings
+
+---
+
+## Phase 7 — Implementation Plan
+
+Step-by-step plan (DO NOT implement):
+
+### 7a. Test-first (TDD)
+
+1. Unit tests for new functionality
+2. Integration tests for cross-component behavior
+3. Smoke tests for quick validation
+4. **Real agentic tests** (REQUIRED):
+   ```python
+   from praisonaiagents import Agent
+   agent = Agent(name="test", instructions="You are helpful")
+   result = agent.start("Say hello in one sentence")
+   print(result)  # Must call LLM and produce response
+   ```
+
+### 7b. Implementation order
+
+1. Tests (TDD)
+2. Core implementation
+3. CLI integration
+4. Documentation
+5. Verification
+
+### 7c. Files to change/create
+
+| File | Action | Purpose |
+|------|--------|---------|
+| | | |
+
+### 7d. Verification commands
+
+```bash
+# Unit tests
+pytest tests/unit/test_<feature>.py -v
+
+# Integration tests
+pytest tests/integration/test_<feature>.py -v
+
+# Smoke test
+python -c "from praisonaiagents import <Feature>; print('OK')"
+
+# Real agentic test
+python examples/<feature>_example.py
+```
+
+---
+
+## Phase 8 — Draft GitHub Issue
+
+The issue must be **self-contained**. Another agent must be able to implement by reading only the issue.
+
+### Required sections

+
+## Phase 9 — Create GitHub Issue
+
+### 9a. Create via `gh` CLI
+
+```bash
+gh issue create \
+  --repo MervinPraison/PraisonAI \
+  --title "<Type>: <Descriptive Title>" \
+  --body "<issue body>"
+```
+
+**Title formats:**
+- `Feature: <What>` — new functionality
+- `Analysis: <Topic>` — analysis/research
+- `Integration: <External System>` — external integration
+- `Fix: <Problem>` — bug fix proposal
+
+### 9b. Verify issue created
+
+```bash
+gh issue view <number> --repo MervinPraison/PraisonAI | head -20
+```
+
+---
+
+## Checklist — Before Creating Issue
+
+- [ ] Acceptance criteria defined and testable
+- [ ] All relevant PraisonAI files read (not skimmed)
+- [ ] External sources researched (if applicable)
+- [ ] Gap analysis completed with severity ratings
+- [ ] Critical review identifies risks and mitigations
+- [ ] Implementation plan is step-by-step with file list
+- [ ] Issue body has working code examples (not pseudocode)
+- [ ] All file paths are absolute and verified
+- [ ] CLI commands are copy-pastable
+- [ ] Acceptance criteria are verifiable (not vague)
+- [ ] References section includes all URLs
+- [ ] Issue is self-contained — no "see docs" without details
+
+---
+
+## Quick Reference — Common Mistakes
+
+| Mistake | Fix |
+|---------|-----|
+| Pseudocode in examples | Use real, runnable code with imports |
+| Vague file paths | Use absolute paths |
+| Skipping gap analysis | Every gap needs severity + impact |
+| Missing real agentic test | Include `agent.start()` test, not just construction |
+| No verification commands | Include copy-pastable pytest/python commands |
+| Claiming "done" without evidence | Every claim references specific files/symbols |
+| Implementing instead of analyzing | This workflow produces issues, not code |
+
+---
+
+## Hard Rules
+
+1. **DO NOT implement** — this workflow produces analysis and issues only
+2. **DO NOT claim done** without evidence
+3. **Every claim must reference** specific files/symbols
+4. **Issue must be self-contained** — implementer needs no follow-up questions
+5. **Working code examples required** — no pseudocode

+ISSUE_NUM=$(gh issue view <number> --repo MervinPraison/PraisonAI --json number --jq '.number')
+echo "Tracking issue #$ISSUE_NUM"
+```
+
+---
+
+# PART B — IMPLEMENTATION MONITORING (Phases 10–15)
+
+After the issue is filed, other agents (`@claude`, GitHub Copilot agent, CodeRabbit) pick it up automatically. This part watches, shepherds, validates, and merges.
+
+## Phase 10 — Wait ~10 min for implementing agents
+
+After `gh issue create`, Claude and Copilot typically start work within seconds and finish a first pass in 5–15 minutes.
+
+```bash
+echo "Waiting 10 minutes for implementing agents..."
+echo "Start: $(date)"
+sleep 600
+echo "End: $(date)"
+```
+
+### Then check: did they open a PR?
+
+```bash
+REPO=MervinPraison/PraisonAI
+ISSUE_NUM=<number>
+
+# Check for PRs that reference the issue
+gh pr list --repo $REPO --state open --search "fixes #$ISSUE_NUM OR closes #$ISSUE_NUM" --json number,title,headRefName
+
+# Also check for branches matching claude/issue-<N>-* naming convention
+gh api repos/$REPO/branches --paginate --jq ".[] | select(.name | startswith(\"claude/issue-$ISSUE_NUM\")) | .name"
+```
+
+---
+
+## Phase 11 — Create PR if none exists
+
+If Claude pushed a branch but did not open a PR, open one yourself.
+
+```bash
+REPO=MervinPraison/PraisonAI
+ISSUE_NUM=<number>
+BRANCH=$(gh api repos/$REPO/branches --paginate --jq ".[] | select(.name | startswith(\"claude/issue-$ISSUE_NUM\")) | .name" | head -1)
+
+if [ -n "$BRANCH" ]; then
+  TITLE=$(gh api repos/$REPO/commits/$BRANCH --jq '.commit.message' | head -1)
+  gh pr create --repo $REPO --head "$BRANCH" --base main \
+    --title "$TITLE" \
+    --body "Automated PR from Claude's work on issue #$ISSUE_NUM.
+
+Branch: \`$BRANCH\`
+
+Closes #$ISSUE_NUM"
+fi
+```
+
+### If no branch exists after 10 minutes
+
+Re-trigger Claude by commenting on the issue, then wait another 10 minutes and re-check:
+
+```bash
+gh issue comment $ISSUE_NUM --repo $REPO \
+  --body "@claude please pick up this issue — full analysis and plan are in the issue body."
+sleep 600
+```
+
+---
+
+## Phase 12 — Wait ~10 min for reviewing agents
+
+Once a PR exists, `CodeRabbit`, `Copilot`, and CI pipelines run. Give them time to complete.
+
+```bash
+echo "Waiting 10 minutes for PR reviewers and CI..."
+sleep 600
+```
+
+### Collect status
+
+```bash
+PR=<pr-number>
+gh pr view $PR --repo $REPO --json state,mergeable,mergeStateStatus,updatedAt,commits,files \
+  | python -c "
+import json,sys
+d=json.load(sys.stdin)
+print(f\"  State: {d['state']}  Mergeable: {d['mergeable']}  MergeState: {d['mergeStateStatus']}\")
+print(f\"  Commits: {len(d['commits'])}\")
+for f in d['files']:
+    print(f\"    {f['path']}: +{f['additions']} -{f['deletions']}\")
+"
+
+# CI & review checks
+gh pr view $PR --repo $REPO --json statusCheckRollup > /tmp/pr-checks.json
+python -c "
+import json
+for c in json.load(open('/tmp/pr-checks.json'))['statusCheckRollup']:

+    if s and s not in ('SKIPPED',):
+        print(f'  {name}: {s}')
+"
+```
+
+---
+
+## Phase 13 — Validate the PR locally
+
+**Never merge an unvalidated PR.** Always clone the branch and run tests.
+
+```bash
+REPO_URL=https://github.com/MervinPraison/PraisonAI.git
+BRANCH=<branch-name>
+WORKDIR=/tmp/pr-validate
+
+rm -rf $WORKDIR
+git clone --depth 1 --branch "$BRANCH" $REPO_URL $WORKDIR
+cd $WORKDIR
+
+# Files touched by the PR
+gh pr view $PR --repo $REPO --json files --jq '.files[].path'
+
+# Run the tests for changed files — ALWAYS use timeout (user global rule)
+timeout 120 python -m pytest <test-paths> -v --tb=short
+
+# Critical invariant checks (adapt per feature):
+# 1) Lazy-import: heavy deps never imported at module level
+timeout 30 python - <<'PY'
+import sys
+from praisonai.observability import <NewThing>  # example
+assert 'heavy_dep' not in sys.modules, "eager import — violates AGENTS.md §4.2"
+print("OK: lazy import preserved")
+PY
+
+# 2) Cold-import benchmark (no regression)
+timeout 30 python -c "import time; t=time.time(); import praisonaiagents; print(f'{(time.time()-t)*1000:.1f} ms')"
+```
+
+### Mergeability gate
+
+A PR is **ready to merge only if ALL of these are true**:
+
+- [ ] `gh pr view` reports `mergeable=MERGEABLE` and `mergeStateStatus` in `CLEAN`/`UNSTABLE` (not `DIRTY`/`BLOCKED`).
+- [ ] All `test (3.x)` matrix jobs report `SUCCESS`.
+- [ ] Local `pytest` on the changed test files passes with **zero failures** (skipped/xfailed tests are OK).
+- [ ] Lazy-import invariant preserved (if the feature adds an optional dep).
+- [ ] Cold-import time within ±2 % of `main` (AGENTS.md §4.2).
+- [ ] No files outside the issue's declared scope were changed.
+- [ ] The diff respects all invariants in AGENTS.md §4.6.
+
+If **any** is false → go to Phase 14 (feedback). Do not merge.
+
+---
+
+## Phase 14 — Feedback to `@claude` when issues found
+
+When validation fails, post a precise, actionable comment tagging `@claude`, referencing the exact test name, error, file, and the AGENTS.md principle violated.
+
+```bash
+gh pr comment $PR --repo $REPO --body "$(cat <<'EOF'
+Hold on merge: validated locally on HEAD `<short-sha>` and found these issues:
+
+**Test failures:**
+```
+FAILED tests/.../test_x.py::TestY::test_z
+  AssertionError: <actual-message>
+```
+
+**Root cause:** <one-line diagnosis referencing the exact file and line>.
+
+**AGENTS.md violation(s):**
+- §<section>: <principle>
+
+**Requested fix (minimal):**
+- Change `<file>:<line>` to `<what>`.
+- Or update the test assertion to `<what>` (if the test is wrong, not the code).
+
+**What already passes:**
+- N/M tests pass.
+- Lazy-import invariant preserved ✅ (or not — state explicitly).
+
+@claude please push a fix. Follow AGENTS.md principles: minimal change, protocol-driven, no perf impact, lazy imports, backward-compatible, safe defaults. Make sure the PR is robust — run the tests locally before force-pushing.
+EOF
+)"
+```
+
+### Loop
+
+After commenting:
+
+```bash
+echo "Waiting 10 minutes for Claude to push fixes..."
+sleep 600
+# → return to Phase 12 (fetch new commits, re-run checks)
+```
+
+Repeat Phases 12 → 13 → 14 until the mergeability gate in Phase 13 is fully green, or escalate to a human after 3 failed rounds.
+
+### When the PR has merge conflicts
+
+If `mergeStateStatus=DIRTY`, ask Claude to rebase rather than resolving conflicts yourself on non-trivial logic:
+
+```bash
+gh pr comment $PR --repo $REPO --body "@claude this PR has merge conflicts with \`main\` (PR #<X> was merged, touching the same regions). Please rebase onto latest \`main\`, re-run \`pytest <paths>\`, and force-push."
+```
+
+---
+
+## Phase 15 — Merge to `main`
+
+Once Phase 13's gate is fully green:
+
+### 15a. Final diff review against AGENTS.md
+
+```bash
+gh pr diff $PR --repo $REPO | less
+```
+
+**Hard gate — every box must be ticked before merge:**
+
+- [ ] **Protocol-driven core (§4.1)**: no heavy implementations leaked into `praisonaiagents`.
+- [ ] **No perf impact (§4.2)**: lazy imports confirmed; import benchmark within ±2 %.
+- [ ] **DRY (§4.3)**: no new duplication; existing protocols/adapters reused where possible.
+- [ ] **Agent-centric (§4.4)**: API centers on agents/sessions/tools/memory.
+- [ ] **Async-safe + multi-agent safe (§4.5)**: no shared mutable globals; locks where needed.
+- [ ] **Invariants preserved (§4.6)**: backward compatible, safe defaults, deterministic tests.
+- [ ] **Naming conventions (§4.9)**: `XProtocol` for interfaces, `XAdapter` for impls, `add_*`/`get_*`/`save`/`load` verbs.
+- [ ] No `.md` files added beyond those explicitly requested (per user global rule).
+- [ ] Tests run locally with `timeout` — never hang (per user global rule).
+
+### 15b. Merge
+
+```bash
+gh pr merge $PR --repo $REPO --squash --delete-branch
+# --squash preserves linear main; --delete-branch keeps the repo clean

+## Checklist — Before Merging
+
+- [ ] Issue exists and describes the work
+- [ ] PR exists and references the issue (`Closes #N`)
+- [ ] Branch was fetched and tests were run **locally** — not just CI-trusted
+- [ ] All PR-relevant tests pass with zero failures
+- [ ] CI matrix (3.10 / 3.11 / 3.12) is all green
+- [ ] Lazy-import / cold-import invariants verified if optional deps added
+- [ ] Diff reviewed against every AGENTS.md §4 principle
+- [ ] `mergeStateStatus` in `CLEAN`/`UNSTABLE`, never `DIRTY`/`BLOCKED`
+- [ ] No files outside the issue's scope were changed
+- [ ] If feedback was given, `@claude` had a chance to respond and fixed everything
+
+---
+
+## Quick Reference — Common Mistakes
+
+| Mistake | Fix |
+|---------|-----|
+| Merging without running tests locally | Always `git clone` the branch and run `pytest` |
+| Resolving complex conflicts manually | Ask `@claude` to rebase instead |
+| Trusting CI alone | CI jobs can be skipped / out-of-date; local validation is source of truth |
+| Vague feedback to `@claude` | Every comment must cite file, line, test name, error, and AGENTS.md section |
+| Waiting forever | Cap loops at 3 rounds, then escalate to a human |
+| Running commands without `timeout` | Always `timeout 60 ...` per user global rule |
+| Creating `.md` docs proactively | Don't — user rule forbids unrequested `.md` files |
+| Skipping diff review | Every merge needs a full-diff AGENTS.md pass |
+
+---
+
+## Hard Rules
+
+1. **Never merge without local test validation.**
+2. **Never merge when `mergeStateStatus = DIRTY` or `BLOCKED`.**
+3. **Every `@claude` comment must be actionable** — file, line, exact fix, AGENTS.md ref.
+4. **Cap feedback loops at 3 rounds** — escalate after that, don't spin forever.
+5. **Use `--squash --delete-branch`** to keep `main` linear and the repo clean.
+6. **Always verify** the issue auto-closed after merge.
+7. **All `run_command` calls use `timeout`** to avoid hangs (user global rule).
+8. **No proactive `.md` creation** beyond this workflow file (user global rule).

+This module consolidates sync/async execution paths into a single async-first

+chat()/achat() and execute_tool()/execute_tool_async().
+
+Architecture:
+- Single async core: _unified_chat_impl() contains all business logic
+- Sync bridge: chat() delegates to asyncio.run() or run_coroutine_threadsafe
+- Maintains full backward compatibility for public APIs
+- Zero performance regression (sync calls still work efficiently)
+
+Design principles:
+- Protocol-driven: follows existing chat_mixin patterns
+- DRY: eliminates duplicate retrieval, hooks, guardrail, tool logic
+- Agent-centric: preserves all existing Agent functionality
+- Async-safe: handles event loop management correctly

+Streaming Protocol Extension - implements Gap 3 from Issue #1392.
+
+This module completes the streaming adapter pattern by extending LLM adapters
+with comprehensive streaming capabilities, removing provider-specific conditionals
+from the core LLM loop.
+
+Architecture:
+- Extends existing LLMProviderAdapterProtocol with streaming interface
+- Each adapter owns its streaming decisions and error recovery  
+- Core llm.py contains no provider-name conditionals for streaming
+- StreamEvent protocol is used consistently for all streaming deltas
+- Observable fallback events instead of silent streaming->non-streaming fallback
+
+Design principles:
+- Protocol-driven: complete the existing adapter pattern
+- DRY: eliminate scattered streaming conditionals
+- Extensibility: new providers = new adapter only (no core changes)
+- Observable: emit events for streaming capability decisions
