From 5c70d1b1a2dce8494fd86293f8eff5234099428f Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 8 Nov 2025 01:14:05 +0000 Subject: [PATCH 1/9] Add Livebook integration for interactive learning This commit introduces a comprehensive Livebook-based interactive learning system to complement the existing workbooks and study guides. ## Changes ### Infrastructure - Updated mix.exs with Kino dependencies (kino, kino_vega_lite, kino_db) - Created livebooks/ directory structure for all 15 phases - Added `make livebook` target to Makefile - Created .progress.json for tracking student progress ### Interactive Notebooks (Phase 1) Created 7 executable livebooks for Phase 1 (Elixir Core): 1. 01-pattern-matching.livemd - Pattern matching & guards 2. 02-recursion.livemd - Tail-call optimization & accumulators 3. 03-enum-stream.livemd - Eager vs lazy evaluation with benchmarks 4. 04-error-handling.livemd - Tagged tuples & with statements 5. 05-property-testing.livemd - StreamData & property-based testing 6. 06-pipe-operator.livemd - Pipelines & data structures 7. 07-advanced-patterns.livemd - Final challenge: Statistics calculator ### Support Files - setup.livemd - Onboarding guide with environment checks - dashboard.livemd - Progress tracking with VegaLite visualizations - livebooks/README.md - Comprehensive usage guide ### Smart Cells - lib/livebook_extensions/test_runner.ex - Run Mix tests for labs apps - lib/livebook_extensions/k6_runner.ex - Execute k6 load tests ### Documentation Updates - README.md - Added "Getting Started with Livebook" section - LESSON-PLANNING-SYSTEM.md - Added Livebook as 5th learning layer ## Features - **Interactive execution**: Students run code directly in browser - **Visual feedback**: Benchmarks and progress charts with VegaLite - **Self-assessment**: Kino forms track understanding of each concept - **Progress tracking**: JSON-based persistence across sessions - **Property testing**: Integrated StreamData examples and exercises - **Real-world challenges**: Statistics calculator with CSV streaming ## Benefits - Eliminates copy-paste to IEx workflow - Immediate feedback on exercises - Encourages experimentation - Visual learning with charts and benchmarks - Consistent progress tracking across all phases ## Testing All 7 Phase 1 livebooks have been tested with: - Executable code cells - Interactive forms and visualizations - Self-assessment checklists - Navigation between checkpoints --- Makefile | 3 + README.md | 25 + docs/LESSON-PLANNING-SYSTEM.md | 57 +- lib/livebook_extensions/k6_runner.ex | 119 ++++ lib/livebook_extensions/test_runner.ex | 117 ++++ livebooks/.progress.json | 1 + livebooks/README.md | 270 +++++++++ livebooks/dashboard.livemd | 365 +++++++++++ .../phase-01-core/01-pattern-matching.livemd | 282 +++++++++ livebooks/phase-01-core/02-recursion.livemd | 352 +++++++++++ livebooks/phase-01-core/03-enum-stream.livemd | 442 ++++++++++++++ .../phase-01-core/04-error-handling.livemd | 425 +++++++++++++ .../phase-01-core/05-property-testing.livemd | 441 ++++++++++++++ .../phase-01-core/06-pipe-operator.livemd | 458 ++++++++++++++ .../phase-01-core/07-advanced-patterns.livemd | 566 ++++++++++++++++++ livebooks/setup.livemd | 224 +++++++ mix.exs | 6 +- 17 files changed, 4151 insertions(+), 2 deletions(-) create mode 100644 lib/livebook_extensions/k6_runner.ex create mode 100644 lib/livebook_extensions/test_runner.ex create mode 100644 livebooks/.progress.json create mode 100644 livebooks/README.md create mode 100644 livebooks/dashboard.livemd create mode 100644 livebooks/phase-01-core/01-pattern-matching.livemd create mode 100644 livebooks/phase-01-core/02-recursion.livemd create mode 100644 livebooks/phase-01-core/03-enum-stream.livemd create mode 100644 livebooks/phase-01-core/04-error-handling.livemd create mode 100644 livebooks/phase-01-core/05-property-testing.livemd create mode 100644 livebooks/phase-01-core/06-pipe-operator.livemd create mode 100644 livebooks/phase-01-core/07-advanced-patterns.livemd create mode 100644 livebooks/setup.livemd diff --git a/Makefile b/Makefile index 3cb4384..739654d 100644 --- a/Makefile +++ b/Makefile @@ -59,3 +59,6 @@ load: ## Run load tests smoke: ## Run smoke tests k6 run tools/k6/smoke.js + +livebook: ## Start Livebook server + livebook server --home livebooks/ diff --git a/README.md b/README.md index eae5210..3cfe6ad 100644 --- a/README.md +++ b/README.md @@ -54,6 +54,31 @@ make db-up make fmt ``` +## 📓 Getting Started with Livebook + +Interactive learning notebooks are available in `livebooks/`. + +```bash +# Install dependencies (includes Kino for Livebook) +mix deps.get + +# Start Livebook server +make livebook + +# Open your browser to http://localhost:8080 +# Navigate to setup.livemd to begin +``` + +**What's in Livebook?** + +- **Interactive exercises** -

Mon Sep 17 00:00:00 2001 From: chops Date: Sun, 9 Nov 2025 17:43:50 -0700 Subject: [PATCH 4/9] Add LLM integration to Jido educational AI agents MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds real LLM support to all three educational AI agents (Code Review, Study Buddy, Progress Coach) while maintaining backward compatibility with simulated mode. ## New Modules - **LabsJidoAgent.LLM**: Multi-provider LLM abstraction - Supports OpenAI, Anthropic (Claude), and Google Gemini - Configurable via LLM_PROVIDER environment variable - Three model tiers: :fast, :balanced, :smart - Automatic fallback to simulated mode when no API key - **LabsJidoAgent.Schemas**: Ecto schemas for structured LLM responses - CodeReviewResponse with embedded CodeIssue schemas - StudyResponse for Q&A interactions - ProgressAnalysis with recommendations - Full validation via changesets ## Updated Actions All three actions now support real LLM integration: - **CodeReviewAction**: Uses GPT-4/Claude for code analysis - Structured feedback with severity levels - Educational suggestions appropriate for learning phase - Falls back to pattern-based analysis if LLM unavailable - **StudyBuddyAction**: LLM-powered Q&A with three modes - :explain - Direct explanations - :socratic - Guided learning through questions - :example - Code examples with explanations - Context-aware responses based on learning phase - **ProgressCoachAction**: Personalized coaching recommendations - Analyzes student progress data - Identifies strengths and challenges - Suggests next phases with reasoning - Estimates time to completion ## Updated Agents All agent wrapper functions now accept :use_llm option: - CodeReviewAgent.review/2 - StudyBuddyAgent.ask/2 - ProgressCoachAgent.analyze_progress/3 Default is use_llm: true, allowing tests to force simulated mode with use_llm: false. ## Documentation - .env.example: Template for API key configuration - LLM_SETUP.md: Comprehensive setup and usage guide - Getting API keys for all three providers - Model selection and cost considerations - Usage examples and troubleshooting - Architecture overview ## Testing All 14 existing tests pass without API keys (simulated mode). The system gracefully falls back to simulated responses if: - No API key is configured - LLM request fails - use_llm: false is explicitly set This ensures the application works in all environments while providing enhanced educational feedback when LLM is available. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- apps/labs_jido_agent/.env.example | 18 ++ apps/labs_jido_agent/LLM_SETUP.md | 224 ++++++++++++++++++ .../lib/labs_jido_agent/code_review_action.ex | 155 ++++++++++-- .../lib/labs_jido_agent/code_review_agent.ex | 3 +- .../lib/labs_jido_agent/llm.ex | 152 ++++++++++++ .../labs_jido_agent/progress_coach_action.ex | 116 +++++++-- .../labs_jido_agent/progress_coach_agent.ex | 6 +- .../lib/labs_jido_agent/schemas.ex | 116 +++++++++ .../lib/labs_jido_agent/study_buddy_action.ex | 78 +++++- .../lib/labs_jido_agent/study_buddy_agent.ex | 3 +- 10 files changed, 823 insertions(+), 48 deletions(-) create mode 100644 apps/labs_jido_agent/.env.example create mode 100644 apps/labs_jido_agent/LLM_SETUP.md create mode 100644 apps/labs_jido_agent/lib/labs_jido_agent/llm.ex create mode 100644 apps/labs_jido_agent/lib/labs_jido_agent/schemas.ex diff --git a/apps/labs_jido_agent/.env.example b/apps/labs_jido_agent/.env.example new file mode 100644 index 0000000..f4b20b0 --- /dev/null +++ b/apps/labs_jido_agent/.env.example @@ -0,0 +1,18 @@ +# LLM Provider Configuration +# Choose one: openai, anthropic, or gemini +LLM_PROVIDER=openai + +# OpenAI Configuration +# Get your API key from: https://platform.openai.com/api-keys +OPENAI_API_KEY=sk-proj-... + +# Anthropic Configuration +# Get your API key from: https://console.anthropic.com/settings/keys +ANTHROPIC_API_KEY=sk-ant-... + +# Google Gemini Configuration +# Get your API key from: https://aistudio.google.com/app/apikey +GEMINI_API_KEY=... + +# Note: You only need to set the API key for the provider you're using. +# The system will automatically fall back to simulated mode if no API key is configured. diff --git a/apps/labs_jido_agent/LLM_SETUP.md b/apps/labs_jido_agent/LLM_SETUP.md new file mode 100644 index 0000000..57bc679 --- /dev/null +++ b/apps/labs_jido_agent/LLM_SETUP.md @@ -0,0 +1,224 @@ +# LLM Integration Setup Guide + +This guide explains how to configure the LabsJidoAgent educational AI system to use real LLM providers. + +## Overview + +LabsJidoAgent supports three LLM providers: +- **OpenAI** (GPT-4, GPT-3.5) +- **Anthropic** (Claude 3.5 Sonnet, Claude 3 Haiku) +- **Google Gemini** (Gemini 1.5 Pro, Gemini 1.5 Flash) + +The system automatically falls back to simulated mode if no API key is configured, ensuring the application works without requiring LLM access. + +## Quick Start + +1. **Copy the environment template:** + ```bash + cp .env.example .env + ``` + +2. **Choose your provider and add your API key:** + + Edit `.env` and set: + ```bash + LLM_PROVIDER=openai # or anthropic, or gemini + OPENAI_API_KEY=sk-proj-your-key-here + ``` + +3. **Load environment variables before running:** + ```bash + source .env + mix test + ``` + + Or use `direnv` for automatic loading: + ```bash + echo "dotenv" >> .envrc + direnv allow + ``` + +## Getting API Keys + +### OpenAI +1.

Changed params from map to keyword list for Instructor.chat_completion - Pass API key and config as second argument, not in params - Added required config fields: api_key, api_url, http_options 2. **Schema simplification** - Changed embeds_many to {:array, :map} in Ecto schemas - Instructor 0.0.5 doesn't support embeds_many properly - CodeReviewResponse.issues now array of maps - ProgressAnalysis.recommendations now array of maps 3. **Code updates for map handling** - Updated format_suggestions to handle string/atom keys - Updated recommendation_to_map to handle both formats - Removed unused issue_to_map function 4. **Test improvements** - Added test_llm.exs for manual LLM testing - All 14 tests still pass ## Testing Successfully tested all three agents with real OpenAI API: - Code Review: Generates scores, identifies issues, provides suggestions - Study Buddy: Answers questions with concepts and resources - Progress Coach: Analyzes progress and gives recommendations All agents correctly show llm_powered: true when using LLM and fall back to simulated mode when LLM unavailable. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../lib/labs_jido_agent/code_review_action.ex | 27 +++--- .../lib/labs_jido_agent/llm.ex | 27 +++++- .../labs_jido_agent/progress_coach_action.ex | 11 +-- .../lib/labs_jido_agent/schemas.ex | 10 +-- apps/labs_jido_agent/test_llm.exs | 89 +++++++++++++++++++ 5 files changed, 134 insertions(+), 30 deletions(-) create mode 100644 apps/labs_jido_agent/test_llm.exs diff --git a/apps/labs_jido_agent/lib/labs_jido_agent/code_review_action.ex b/apps/labs_jido_agent/lib/labs_jido_agent/code_review_action.ex index c565ce7..72decc2 100644 --- a/apps/labs_jido_agent/lib/labs_jido_agent/code_review_action.ex +++ b/apps/labs_jido_agent/lib/labs_jido_agent/code_review_action.ex @@ -65,10 +65,10 @@ defmodule LabsJidoAgent.CodeReviewAction do temperature: 0.3 ) do {:ok, %Schemas.CodeReviewResponse{} = review} -> -

212 **Recursion in Elixir**
213
214 Recursion is when a function calls itself. In Elixir, it's fundamental for processing lists.
215
216 **Key Concepts:**
217 1. **Base case** - Stops recursion
218 2. **Recursive case** - Calls itself with modified arguments
219
220 **Example:**
221 ```elixir
222 def sum([]), do: 0
223 def sum([h | t]), do: h + sum(t)
224 ```
225
226 **Important**: For large lists, use tail-call optimization with an accumulator.

230 """
231 **Tail-Call Optimization (TCO)**
232
233 A tail-recursive function has the recursive call as the LAST operation.
234
235 **Non-tail-recursive** (builds up stack):
236 ```elixir
237 def sum([]), do: 0
238 def sum([h | t]), do: h + sum(t) # Addition happens AFTER
239 ```
240
241 **Tail-recursive** (constant stack):
242 ```elixir
243 def sum(list), do: sum(list, 0)
244 defp sum([], acc), do: acc
245 defp sum([h | t], acc), do: sum(t, acc + h) # Call is LAST

2494 :pattern_matching ->
250 """
251 **Pattern Matching**
252
253 The `=` operator matches left to right in Elixir.

256 - `{:ok, value} = {:ok, 42}`
257 - `[head | tail] = [1, 2, 3]`
258 - `%{name: n} = %{name: "Alice", age: 30}`
