Take time to read through any examples you are given and understand what it does. The AI model may not be using up-to-date information when it is helping you, or can even hallucinate nonexistent code as truth, so you should only trust code that you are able to back up with your own knowledge or by checking against relevant documentation. - To get more accurate information, specify any context that you want the bot to have. The more information it has, the better results it will be able to return for your use case. This includes providing relevant code snippets, error messages, desired outcomes, and constraints. - Be aware that chat tools are not always reliable, and the results of what it gives you are never guaranteed. You should never let AI have the final say on handling sensitive or valuable information or infrastructure. -- Don't depend on long lived chats. As you talk to a chat bot for longer, it will continue to take note of your unique situation, however, this can lead to hallucinations that take priority over knowledge from the internet. It is important to be aware of how long your chats are living, and start fresh ones if you feel that the data you are getting is less factual and tailored too much to your own code. +- **Manage context window utilization proactively.** As conversations with AI assistants grow longer, they accumulate context that can lead to performance degradation—a phenomenon called "context rot." Research shows that when context window utilization exceeds 40%, LLM performance degrades significantly, with reasoning capabilities declining and hallucinations increasing. This happens because the model struggles to effectively process and prioritize information when the context becomes too full. To combat this, apply **intentional compaction** when you notice context utilization approaching 60% or when responses become less accurate. Compaction involves distilling your conversation into essential information, starting a fresh chat with a concise summary, and progressively loading only the context needed for your current task. This practice maintains AI effectiveness throughout longer development sessions while preventing the "dumb zone" that emerges in overloaded context windows. - Be aware of what these tools are doing with your data. You should only use tools that will use your data ethically. Some organizations may prohibit the use of AI tools entirely, or only use internal chat bots, to protect the integrity of potentially sensitive data that they are handling. Always check your organization's policy. - AI is only as smart as the internet it is trained on. Chat bots are essentially just a powerful, opinionated google search, and can only give you information from someone on the internet, but likely will not be able to check the validity of the claims it gives you. It is a good habit to verify anything you get from a chat bot before deciding to use it. +## Understanding Context Windows + +When you interact with an AI assistant, everything in your conversation—your messages, the AI's responses, any code or documents you share—gets stored in what's called a **context window**. Think of this as the AI's working memory for your conversation. + +### What Are Context Windows? + +A context window is the total amount of information (measured in tokens) that an AI model can consider at once. Different AI models have different context window sizes: + +- **Smaller models**: 8,000-16,000 tokens (roughly 6,000-12,000 words) +- **Medium models**: 32,000-64,000 tokens (roughly 24,000-48,000 words) +- **Large models**: 128,000-200,000+ tokens (roughly 96,000-150,000+ words) + +A token is approximately 3-4 characters of text, so "Hello, world!" is about 3-4 tokens. Code tends to use more tokens than plain text because of syntax characters and formatting. + +### How LLMs Process Context + +When you send a message to an AI assistant, the model processes your entire conversation history plus your new message. The model: + +1. **Reads the full context** from beginning to end +2. **Identifies patterns and relationships** between different parts of the conversation +3. **Generates a response** based on all available context +4. **Adds the response** to the context window for future messages + +This means each message you send requires the model to re-process everything that came before it. As your conversation grows, this processing becomes more complex and resource-intensive. + +### Why This Matters for AI-Assisted Development + +Understanding context windows is crucial for effective AI-assisted development because: + +- **Context fills up quickly** when working with code. A single medium-sized file can consume thousands of tokens. Copying multiple files, error logs, or documentation into a conversation can exhaust the context window surprisingly fast. +- **Performance degrades as context grows** (see next section on context rot). Once you exceed certain thresholds, the AI's ability to reason effectively diminishes. +- **You can't add context indefinitely**. Eventually you'll hit the model's limit, and older messages will be truncated or lost entirely. +- **Context management becomes a skill**. Learning to provide the right context at the right time—neither too much nor too little—is essential for productive AI collaboration. + +Effective context management means understanding when to start fresh conversations, when to compact existing context, and how to structure your interactions to maintain AI effectiveness throughout your development session. + +## Context Rot and Performance Degradation + +As your conversation with an AI assistant grows longer, you may notice the responses becoming less accurate, more confused, or prone to hallucinations. This phenomenon is called **context rot**, and it's one of the most important challenges to understand in AI-assisted development. + +### What Is Context Rot? + +Context rot occurs when an AI model's performance degrades as the context window fills up. Even though modern AI models have large context windows (100k+ tokens), research from Chroma and others has shown that models become significantly less effective as context utilization increases—particularly when exceeding certain thresholds. + +### The 40% "Dumb Zone" + +Research has identified a critical threshold: **when context window utilization exceeds 40%, LLM reasoning capabilities begin to degrade noticeably**. This degradation manifests as: + +- **Increased hallucinations**: The model starts fabricating details or "remembering" things that weren't actually in the context +- **Reduced reasoning ability**: Complex problem-solving becomes less reliable +- **Context confusion**: The model may conflate different parts of the conversation or lose track of what's been discussed +- **Instruction following deterioration**: The model becomes less consistent at following your instructions + +Some research suggests that models can effectively handle approximately **150-200 high-quality instructions** before performance degradation becomes significant. Once you've exceeded this threshold, you're operating in what practitioners call the "dumb zone"—where the AI still responds but with noticeably reduced effectiveness. + +### Real-World Symptoms You'll Encounter + +As you work with AI assistants throughout this bootcamp and beyond, watch for these warning signs of context rot: + +- **Repetitive suggestions**: The AI starts repeating the same advice or code patterns it already provided +- **Loss of context awareness**: The AI forgets decisions or constraints you established earlier in the conversation +- **Increased verbosity**: Responses become unnecessarily long or circular as the model struggles to focus +- **Code regression**: New code suggestions break patterns or functionality that were working earlier +- **Contradictory advice**: The AI provides guidance that conflicts with its earlier recommendations + +### Why Context Rot Happens + +Context rot occurs because: + +1. **Attention mechanisms have limits**: The model must distribute its "attention" across the entire context. As context grows, attention becomes more diffuse, making it harder to focus on what's most important. +2. **Signal-to-noise degradation**: Early in a conversation, nearly everything is relevant. As context accumulates, irrelevant details (dead-end explorations, discarded approaches, tangential discussions) create noise that obscures the signal. +3. **Computational constraints**: Processing longer contexts requires more compute resources and time, which can lead to shortcuts or approximations that reduce quality. + +Understanding context rot is the first step toward managing it effectively. The next sections will cover practical techniques for preventing and recovering from context rot during your development sessions. + +## Intentional Compaction Techniques + +Rather than letting context rot sneak up on you, professional AI-assisted development requires **intentional compaction**—the practice of deliberately distilling and resetting context to maintain AI effectiveness throughout long development sessions. + +### What Is Intentional Compaction? + +Intentional compaction is the process of: + +1. **Recognizing** when context has become cluttered or is approaching critical thresholds +2. **Distilling** the essential information from your current conversation +3. **Starting fresh** with a new conversation that includes only the necessary context +4. **Continuing work** with restored AI effectiveness + +Think of it as "checkpointing" your conversation—you're preserving what matters while discarding the noise that's degraded performance. + +### When to Trigger Compaction + +You should consider compacting context when: + +- **Context utilization exceeds 60%**: This gives you a buffer before hitting the 40% degradation zone (since context continues growing with each exchange) +- **AI responses degrade noticeably**: You observe the symptoms of context rot discussed in the previous section +- **Transitioning between work phases**: Moving from research to planning, or planning to implementation, is a natural compaction point +- **Before critical tasks**: If you're about to tackle a complex problem, start with a clean context window + +Many AI tools provide context indicators or commands (like `/context` in Claude Code) that help you monitor utilization and make informed compaction decisions. + +### Compaction Strategies + +Different situations call for different compaction approaches: + +#### Research → Plan → Implement Pattern + +This three-phase approach naturally structures compaction: + +1. **Research Phase**: Use AI to explore the codebase, understand patterns, and gather information. Context grows rapidly as you load files and documentation. + +2. **Compaction & Planning Phase**: Start a fresh conversation with a summary of your research findings. Ask the AI to help create an implementation plan based on this distilled context. The plan serves as your compacted context. + +3. **Implementation Phase**: Start another fresh conversation with the plan as your primary context. Progressively load only the specific files you're currently modifying, keeping context lean and focused. + +#### The Summary-and-Reset Pattern + +For simpler tasks: + +1. Ask the AI to summarize the current state: "Please summarize what we've accomplished, what we're currently working on, and what remains to be done." +2. Copy this summary +3. Start a new conversation with: "Context: [paste summary]. Let's continue with [next task]." + +#### The Checkpoint Pattern + +For complex, multi-day projects: + +1. At the end of each work session, create a checkpoint document (e.g., `WORKING_NOTES.md`) +2. Include: current state, decisions made, next steps, relevant file paths +3. Start each new session by loading this checkpoint document +4. Update the checkpoint as you progress + +### Practical Examples + +**Example 1: Compacting During Bug Investigation** + +Instead of: +```text +[150+ messages of debugging, log analysis, hypothesis testing] +"The AI is now confused and suggesting things we already tried" +``` + +Apply compaction: +```text +New conversation: "I'm investigating a bug where user authentication fails intermittently. +Through testing I've determined: [3-bullet summary of findings]. +The relevant code is in auth/login.ts:45-67 [provide file]. +Help me identify the root cause and fix." +``` + +**Example 2: Compacting When Switching Phases** + +After research phase: +```text +New conversation: "I'm implementing a new feature: [brief description]. +Based on codebase analysis, I should: [3-4 key patterns to follow]. +The relevant files are: [list with brief descriptions]. +Let's start by creating a specification for this feature." +``` + +### Tips for Effective Compaction + +- **Be ruthless about what to keep**: If something didn't lead anywhere useful, leave it behind +- **Preserve decisions and constraints**: These are critical context that should survive compaction +- **Use file:line references**: Instead of copying entire files, reference them (e.g., "see auth.ts:23-45") and load them on-demand +- **Document as you go**: Keeping brief notes makes compaction easier and faster +- **Practice regularly**: Compaction is a skill that improves with deliberate practice + +Intentional compaction transforms AI assistance from a sprint (which degrades after 150-200 instructions) into a marathon where you maintain effectiveness indefinitely. + +## Progressive Disclosure Patterns + +While intentional compaction helps you manage existing context, **progressive disclosure** is a complementary strategy that prevents context bloat in the first place. Progressive disclosure means providing context to the AI incrementally—loading information on-demand as it becomes relevant rather than front-loading everything at the start. + +### Front-Loading vs. On-Demand Context + +**Front-loading approach** (less effective): +```text +[Message 1] +Here's the entire codebase structure... [5000 tokens] +Here are all the relevant files... [10000 tokens] +Here's the documentation... [3000 tokens] +Now help me fix this small bug in auth.ts +``` + +**Progressive disclosure approach** (more effective): +```text +[Message 1] +I need to fix a bug in auth.ts where login fails. Here's the error: [error message] + +[Message 2] +[After AI asks] Here's the relevant auth.ts code: [specific function] + +[Message 3] +[After AI asks] Here's how we call it from login.ts:45-67 +``` + +Progressive disclosure keeps context lean, ensures the AI focuses on what's immediately relevant, and gives you headroom to go deeper when needed. + +### Structuring Project Context Files + +Many AI tools let you provide project-level context through files like `CLAUDE.md`, `.cursorrules`, or similar configuration. These files are powerful but can quickly bloat context if not structured carefully. + +**Effective project context file structure:** + +1. **Overview section** (100-200 tokens): Brief project description, architecture, and key patterns +2. **Command reference** (50-100 tokens): Essential commands (build, test, lint) +3. **File pointers** (200-300 tokens): Map features to files without including file contents +4. **Conventions** (100-200 tokens): Code style, naming patterns, testing approaches + +**Example of file pointer instead of full file:** + +Instead of: +```markdown +## Authentication Module +[Paste entire auth.ts file - 2000 tokens] +``` + +Use: +```markdown +## Authentication Module +- Login logic: `src/auth/login.ts:23-45` (JWT-based) +- Session management: `src/auth/session.ts:12-67` (Redis-backed) +- User validation: `src/auth/validators.ts` (Zod schemas) +``` + +When the AI needs the actual code, it can request specific files or line ranges, keeping baseline context lean. + +### File:Line References Over Code Copying + +Get in the habit of referencing code locations rather than copying entire files: + +**Less effective:** +```text +"Here's the entire UserService class:" [paste 500 lines] +``` + +**More effective:** +```text +"The issue is in UserService.findById() at src/services/user.ts:89-103" +[Then provide just those lines if the AI asks] +``` + +This approach: +- Keeps context focused on what's relevant +- Makes it easier for you to verify what the AI is looking at +- Allows the AI to request additional context if needed +- Prevents context bloat from peripheral code + +### Avoiding Context Bloat + +Context bloat happens when you inadvertently load unnecessary information. Common sources: + +- **Error dumps**: Posting entire stack traces when the key error is in the first 3 lines +- **Log files**: Sharing 1000 lines of logs instead of the relevant 20 lines +- **Documentation**: Pasting entire API docs when you only need one endpoint +- **Test files**: Loading all tests when you're debugging one specific failure + +**Practice selective context loading:** + +1. **Start minimal**: Provide only what's needed for the immediate question +2. **Let AI request more**: If the AI needs additional context, it will ask +3. **Summarize when possible**: Instead of raw data, provide structured summaries +4. **Use links**: For documentation, provide URLs instead of full-text copies + +### Practical Progressive Disclosure Workflow + +Here's how progressive disclosure might look in practice: + +```text +[Phase 1: Problem statement - 50 tokens] +"I need to add rate limiting to our API endpoints" + +[Phase 2: Architecture context - 200 tokens] +[After AI asks about current setup] +"We use Express.js, middleware pattern, see middleware/index.ts for examples" + +[Phase 3: Specific implementation - 500 tokens] +[After AI proposes approach] +"Here's our current authentication middleware: [paste relevant code]" + +[Phase 4: Testing context - 300 tokens] +[During implementation] +"Here's how we test middleware: [paste test example]" +``` + +Total context used: ~1050 tokens, loaded progressively as needed, each piece directly relevant to the current step. + +Compare to front-loading everything: ~3000+ tokens, most unused, increased noise-to-signal ratio. + +### Tips for Effective Progressive Disclosure + +- **Answer questions precisely**: When the AI asks for context, provide exactly what it requested—no more, no less +- **Trust the AI to ask**: Modern AI assistants are good at identifying what context they need +- **Use project context files wisely**: Keep them lean and pointer-heavy rather than content-heavy +- **Develop a mental model**: Think of context as a scarce resource to be allocated strategically +- **Combine with compaction**: Progressive disclosure prevents bloat; compaction fixes it when it happens + +Progressive disclosure is preventive medicine for context rot. By loading context deliberately and incrementally, you maintain AI effectiveness from the start rather than fighting degradation later. + +## Tracking Context Utilization + +To effectively manage context, you need visibility into how much of your context window is being used. Most modern AI development tools provide mechanisms for monitoring context utilization, allowing you to make informed decisions about when to compact or start fresh. + +### Claude Code: /context Command + +Claude Code provides a built-in `/context` command that displays current context utilization: + +```bash +/context +``` + +This command returns: +- Total tokens used +- Percentage of context window filled +- Breakdown of context sources (messages, files, system instructions) + +**How to use it:** +- Check context before starting complex tasks +- Monitor context when approaching the 40-60% range +- Verify context after compaction to ensure it was effective + +### VSCode AI Tools: Context Indicators + +Many VSCode AI extensions provide visual context indicators: + +- **GitHub Copilot Chat**: Shows token count in the chat interface +- **VSCode status bar indicators**: Some extensions display context usage in the bottom status bar +- **Extension-specific commands**: Check your AI extension's documentation for context monitoring commands + +### Other AI Assistant Tools + +Different AI tools provide varying levels of context visibility: + +- **Cursor**: Built-in context viewer showing token usage and file inclusions +- **Windsurf**: Context tracking in the Cascade interface +- **ChatGPT/Claude web interfaces**: Some show conversation length, though less precise than developer tools + +### Manual Context Estimation + +If your tool doesn't provide precise context tracking, you can estimate: + +- **Message count heuristic**: Roughly 150-200 high-quality back-and-forth exchanges before hitting degradation zones +- **File inclusion tracking**: Keep a mental note of how many files you've loaded (each medium file is ~2000-5000 tokens) +- **Response quality monitoring**: Watch for the symptoms of context rot discussed earlier + +### Establishing Context Monitoring Habits + +Develop these habits for effective context monitoring: + +1. **Check before critical tasks**: Always verify context utilization before important work +2. **Set utilization thresholds**: Decide on your compaction triggers (e.g., "compact at 60%") +3. **Monitor during long sessions**: Check context periodically during extended development sessions +4. **Post-compaction verification**: After compacting, verify that context was successfully reduced +5. **Tool-specific learning**: Learn your specific tool's context monitoring features and make them part of your workflow + +### Context Utilization Red Flags + +Beyond tool indicators, watch for these behavioral red flags that suggest high context utilization even if metrics aren't available: + +- Responses taking noticeably longer to generate +- The AI repeating itself or providing circular advice +- Decreased accuracy or increased hallucinations +- The AI losing track of earlier decisions or constraints +- Your own confusion about what context the AI is working with + +When you observe these patterns, it's time to compact regardless of what metrics show (or don't show). + +### Practical Context Monitoring Workflow + +Here's a typical workflow incorporating context monitoring: + +```text +[Starting a new feature] +1. /context → 5% utilization (clean slate) + +[After research phase] +2. /context → 35% utilization (approaching watch zone) +3.

Generate Specification (SDD Stage 1) + +The first stage of Spec-Driven Development transforms a high-level idea into a comprehensive, developer-ready specification. This specification becomes the source of truth for your implementation, defining goals, requirements, constraints, and success criteria before any code is written. + +**Purpose:** +- Convert informal ideas into structured, actionable specifications +- Establish clear requirements and constraints upfront +- Create a reference document for validation and verification +- Enable parallelization: multiple developers can implement from the same spec +- Provide context for AI assistants throughout development + +**The Clarifying Questions Process:** + +Use a conversational LLM to iteratively refine your idea through a question-based dialogue. The AI should ask one question at a time, building on your previous answers to extract every relevant detail. + +**Example Spec Generation Prompt** (adapted for DevOps Bootcamp): ```text -Ask me one question at a time so we can develop a thorough, step-by-step spec for this idea. +I need to create a specification for a DevOps automation project. Ask me one question at a time to develop a thorough, step-by-step spec. + +Each question should build on my previous answers. Our end goal is a detailed specification covering: +- Project goals and success metrics +- Functional and non-functional requirements +- Architecture and technology choices +- Security and compliance considerations +- Testing strategy +- Deployment approach -Each question should build on my previous answers, and our end goal is to have a detailed specification I can hand off to a developer. Let's do this iteratively and dig into every relevant detail. Only one question at a time. When giving options, always format them in a numbered list. +Only one question at a time. When giving options, format them in a numbered list. -Here's the idea: +Here's the idea: [YOUR_IDEA] ``` -After completing the brainstorming: +**After Completing the Brainstorming:** ```text -Now that we've wrapped up the brainstorming process, compile our findings into a comprehensive, developer-ready specification. Include all relevant requirements, architecture choices, data handling details, error handling strategies, and a testing plan so a developer can immediately begin implementation. +Now compile our findings into a comprehensive, developer-ready specification. Include: +- Executive summary +- Goals and non-goals +- User stories or use cases +- Demoable units of work with proof artifacts +- Technical considerations +- Security and compliance requirements +- Success metrics +- Open questions (if any remain) + +Format this as a structured markdown document that a developer can immediately use for implementation planning. ``` -Save this file as `spec.md`. +**Save and Commit the Specification:** -Here you should practice small batch delivery by committing this spec. In AI assisted development _how_ you generated the content is critical. In your commit message you should include the following: +Save this as `spec.md` or following your project's naming convention (e.g., `[NN]-spec-[feature-name].md`). -* Date generated -* LLM used -* Prompt used -* Parameters tuned (e.g. Temperature, Top P/Top K, etc.) -* Notes on any changes or clarifications +Practice small batch delivery by committing this spec with detailed metadata: -### 2. Planning +**Example Commit Message:** -Take the `spec.md` generated in the previous step and now we will break it down into small, iterative implementation chunks: +```text +docs: add specification for [feature-name] + +- Generated: 2025-01-09 +- Model: Claude Sonnet 4.5 / GPT-4 +- Temperature: 0.7 +- Prompt: Iterative clarifying questions workflow +- Notes: Focused on DevOps automation requirements, emphasized security considerations +``` -* Provide the spec to a reasoning-focused model -* Request a detailed blueprint broken into small steps -* Structure these steps as prompts for a code-generation model +**Resources:** +- [Liatrio Spec-Driven Workflow](https://github.com/liatrio-labs/spec-driven-workflow) - Complete SDD methodology with templates and examples -**Example Prompt**: +### 2. Task Breakdown (SDD Stage 2) + +The second stage transforms your specification into an executable implementation plan. Break the spec into parent tasks representing demoable units of work, each with clear proof artifacts that demonstrate completion. + +**Purpose:** +- Transform specifications into actionable, incremental tasks +- Create parent tasks that represent meaningful milestones +- Define proof artifacts that validate completion +- Identify relevant files and dependencies +- Generate sub-tasks that build toward parent task completion + +**Breaking Specs into Demoable Units:** + +Each parent task should represent work that can be demonstrated, tested, and validated independently. Parent tasks should: +- Deliver working functionality (not partial implementations) +- Have clear, verifiable proof artifacts +- Take 2-8 hours of focused implementation time +- Build logically toward the overall spec goals + +**Creating Parent Tasks with Proof Artifacts:** + +Proof artifacts provide evidence that a task is complete and working as specified. Common proof artifacts include: +- CLI output showing successful execution +- Test results demonstrating functionality +- Screenshots of UI features +- Configuration files showing correct setup +- Performance metrics or logs +- API response examples + +**Example Task Breakdown Prompt:** ```text -Draft a detailed, step-by-step blueprint for building this project. Then, once you have a solid plan, break it down into small, iterative chunks that build on each other. Look at these chunks and then go another round to break it into small steps. From here you should have the foundation to provide a series of prompts for a code-generation LLM that will implement each step in a test-driven manner. +Given this specification, break it into parent tasks that represent demoable units of work. For each parent task: + +1. Provide a clear purpose statement +2. List functional requirements it satisfies +3. Define proof artifacts that demonstrate completion +4. Identify relevant files that will be modified or created +5. Break down into 3-8 sub-tasks that build toward completion + +Each parent task should deliver working, testable functionality. ``` -Save this as something like `prd.md`. Again practice small batch delivery and don't forget prompt details in your commit message. +**Example Task Structure:** + +```text +## Task 1.0: Implement Authentication Middleware + +**Purpose**: Add JWT-based authentication to protect API endpoints + +**Proof Artifacts:** +- CLI output: Successful authentication with valid JWT +- CLI output: 401 Unauthorized with invalid/missing JWT +- Test results: All auth middleware tests passing +- Configuration: Environment variables documented + +**Relevant Files:** +- src/middleware/auth.ts (new) +- src/routes/api.ts (modify) +- tests/middleware/auth.test.ts (new) + +**Sub-tasks:** +1. Create JWT validation utility function +2. Implement authentication middleware +3. Add middleware to protected routes +4. Write unit tests for middleware +5. Write integration tests for protected endpoints +6. Document authentication setup in README +``` + +**Save and Commit:** + +Save this as a tasks file (e.g., `[NN]-tasks-[feature-name].md`). Commit with appropriate metadata: + +```text +docs: add task breakdown for [feature-name] + +- Generated: 2025-01-09 +- Model: Claude Sonnet 4.5 +- Based on: [NN]-spec-[feature-name].md +- Notes: Organized into 6 parent tasks with proof artifacts +``` + +**Alternative Tools:** + +For automated task generation, consider [TaskMaster AI](https://www.task-master.dev/) which provides additional features for task management and includes an MCP server for integration with AI assistants. + +### 3. Execute with Management (SDD Stage 3) + +The third stage executes your task list incrementally while maintaining engineering rigor, context hygiene, and continuous validation. This stage emphasizes single-threaded execution, proof artifact collection, and proactive context management. + +**Purpose:** +- Implement tasks systematically, one sub-task at a time +- Verify functionality at each checkpoint before proceeding +- Maintain proof artifacts as evidence of completion +- Manage context utilization to prevent degradation +- Commit frequently with clear, traceable messages + +**Single-Threaded Execution:** + +Work on exactly one parent task at a time, completing all its sub-tasks before moving to the next. This approach: +- Maintains clear focus and reduces context switching +- Enables meaningful commits at parent task boundaries +- Facilitates proof artifact collection +- Allows for mid-implementation course corrections + +**Verification Checkpoints:** + +After completing each sub-task: +1. **Test the functionality**: Run relevant tests or manual verification +2. **Check code quality**: Run linters, formatters, type checkers +3. **Review implementation**: Ensure it meets requirements and follows patterns +4. **Update task file**: Mark sub-task as complete immediately -?> An alternative to using a reasoning model to generate the PRD is to leverage a tools such as [TaskMaster AI](https://www.task-master.dev/). The idea is very similar though this tool adds additional features. I encourage you to give it a spin and compare it to the simplified method. PS it does have an MCP server +**Context Management During Implementation:** + +As you work through tasks, actively manage context utilization to maintain AI effectiveness (see [AI Best Practices](3.1.4-ai-best-practices.md#context-rot-and-performance-degradation) for detailed coverage): + +- **Monitor context**: Use tools like `/context` in Claude Code or check context indicators in your AI assistant +- **Watch for 40%+ utilization**: Performance degradation begins around 40% context utilization +- **Trigger compaction at 60%+**: When context exceeds 60%, apply intentional compaction before proceeding +- **Phase transitions**: Natural compaction points occur between parent tasks (research → planning → implementation → testing) + +**Compaction Workflow:** + +```text +1. Recognize: Context exceeding 60% or noticing degradation symptoms +2. Summarize: "Summarize our progress: completed tasks, current state, next steps" +3. Start fresh: New conversation with summary as context +4. Load selectively: Add only files/context needed for current task +5. Continue: Resume implementation with restored AI effectiveness +``` + +**Committing After Each Parent Task:** + +Create a git commit after completing each parent task: + +```text +feat: implement authentication middleware + +- Add JWT validation utility function +- Implement auth middleware with error handling +- Integrate middleware into protected routes +- Add comprehensive unit and integration tests +- Document authentication setup and environment variables + +Proof artifacts in docs/specs/[NN]-spec-[feature]/[NN]-proofs/[NN]-task-01-proofs.md + +Related to T1.0 in Spec [NN] +``` + +**Maintaining Proof Artifacts:** + +Create proof artifacts as you complete parent tasks.

Validate Implementation (SDD Stage 4) + +The final stage validates that your implementation fully satisfies the original specification. This systematic review ensures nothing was missed, all proof artifacts demonstrate required functionality, and the implementation is ready for deployment or handoff. + +**Purpose:** +- Verify all spec requirements are satisfied +- Validate proof artifacts demonstrate functionality +- Ensure code quality and testing standards are met +- Confirm documentation is complete and accurate +- Identify any gaps or rework needed + +**Validating Against the Specification:** + +Compare your implementation against the original spec systematically: + +1. **Review each requirement**: For every requirement in the spec, verify corresponding implementation exists +2. **Check success criteria**: Ensure all success metrics defined in the spec are met +3. **Validate constraints**: Confirm technical, security, and operational constraints are satisfied +4. **Test edge cases**: Verify behavior for boundary conditions and error scenarios + +**Reviewing Proof Artifacts:** + +Examine proof artifacts for completeness and accuracy: + +- **Functionality proof**: Does the artifact demonstrate the feature works as specified? +- **Quality proof**: Are tests passing?

numbered sections (e.g., 3.4, 3.5) but will enhance and restructure existing content within the current chapter organization +2. **Coverage of advanced tools like CodeLayer or Cline** - Focus remains on Claude Code, Windsurf, and GitHub Copilot; advanced or emerging tools are excluded to maintain beginner-appropriate scope +3. **Dedicated 12-Factor Agents curriculum** - The 12-Factor Agents methodology will be mentioned in resources/further reading only, not taught comprehensively +4. **Requiring proof artifacts submission** - While proof artifacts will be introduced as best practices, participants will not be required to create or submit them for exercises +5. **Updating other bootcamp chapters** - Changes are strictly limited to Chapter 3 (AI Engineering); other chapters remain unchanged even if they could benefit from AI-related updates +6. **Creating entirely new quiz files** - While existing quiz content may be updated to reflect SDD and context management concepts, no entirely new quiz files will be created where none previously existed +7. **Changing repository documentation standards** - All updates must follow existing patterns; this is not an opportunity to evolve front-matter, exercise structure, or style guide conventions +8. **Creating new video tutorials or multimedia content** - No new videos or interactive media will be produced; however, existing YouTube videos (specifically https://www.youtube.com/watch?v=IS_y40zY-hc) will be embedded in the documentation +9. **Tool-specific installation guides** - Documentation will reference tools and their capabilities but will not provide detailed installation or setup instructions +10. **Integration with external SDD tooling** - While SDD methodology is taught, integration with external SDD tools or automation frameworks is out of scope + +## Design Considerations + +No specific design requirements identified. This update focuses on documentation content rather than visual design or UI elements. All visual components (images, diagrams) currently present in the chapter will be maintained unless they contradict updated methodologies. + +## Repository Standards + +All updates must follow the established repository patterns documented in CLAUDE.md and STYLE.md: + +**Content Standards:** +- Use H3 headers (`###`) as default within pages; H2 headers (`##`) for navigation/table of contents +- Images using HTML `` tags placed in `img/` or chapter-specific image directories (e.g., `img3/`) +- Front-matter YAML template with category, estReadingMinutes, and exercises metadata +- Deliverables sections at the end of each document with bulleted questions +- Quiz components embedded using `
` format +- YouTube videos embedded using Docsify video embedding plugin syntax (e.g., `[video](https://www.youtube.com/watch?v=VIDEO_ID)` or iframe embeds if supported) + +**Technical Standards:** +- Markdown files must pass `npm run lint` validation +- Front-matter must validate with `npm run refresh-front-matter` +- Exercise metadata must include name, description, estMinutes, and technologies array +- Multi-column layouts using `grid2`, `grid3`, `grid4` CSS classes where appropriate + +**Content Philosophy:** +- Minimize new categories and technologies in front-matter; reuse existing ones from master record (docs/README.md) +- Content should be accessible to bootcamp participants (clear, beginner-friendly language) +- Examples and exercises should be practical and directly applicable +- External links should be stable and authoritative sources + +**Version Control:** +- Changes will be committed following Docsify project conventions +- Pre-commit hooks (Husky) will validate front-matter automatically +- Commit messages should clearly describe what sections were updated and why + +## Technical Considerations + +**Markdown Processing:** +- All documentation uses Docsify for rendering; updates must be compatible with Docsify markdown parsing +- Code blocks should use appropriate syntax highlighting (e.g., ```text, ```yaml, ```markdown) +- Internal links use relative paths (e.g., `[3.3.1](3.3.1-agentic-best-practices.md)`) + +**Content Organization:** +- Updates span three primary documentation files: 3.1.4-ai-best-practices.md, 3.3.1-agentic-best-practices.md, 3.3.2-agentic-ide.md +- Updates include one quiz file: src/quizzes/chapter-3/3.3/agentic-best-practices-quiz.js (currently references Harper Reed workflow which will be replaced with SDD) +- Cross-references between sections must remain valid after updates +- Sidebar navigation (docs/_sidebar.md) remains unchanged as no new sections are added + +**Integration Points:** +- Context engineering concepts introduced in 3.1.4 must be referenced in 3.3.1 SDD workflow +- SDD workflow taught in 3.3.1 must be applied in 3.3.2 exercises +- Tool coverage (Claude Code) must be consistent across all mentions + +**Dependency Considerations:** +- No new npm dependencies or build tools required +- Existing linting and front-matter validation scripts must pass +- Changes should not affect webpack build process or Docsify serving + +## Security Considerations + +**Content Security:** +- Examples and exercises must avoid including actual API keys, credentials, or sensitive information +- Placeholders like `[YOUR_API_KEY_HERE]` or `[EXAMPLE_TOKEN]` should be used in all code examples +- Exercise instructions should remind participants not to commit real credentials + +**External Resources:** +- All linked resources (GitHub repositories, external documentation) should be from trusted sources +- Links to HumanLayer, Liatrio Labs, Anthropic, and other established organizations are appropriate +- Avoid linking to personal blogs or unverified sources for core methodology explanations + +**Tool Recommendations:** +- Recommended tools (VSCode with AI assistants, Claude Code, Windsurf, GitHub Copilot) should be mainstream, actively maintained projects +- Participants should be made aware of data privacy considerations when using AI tools +- Existing guidance on organizational policies regarding AI tool usage should be maintained and expanded + +**Proof Artifacts Guidance:** +- While proof artifacts are introduced as a concept, participants should be reminded to sanitize any screenshots or outputs that might contain sensitive information +- Exercise deliverables should emphasize learning outcomes over potentially sensitive proof evidence + +No specific security considerations identified beyond standard documentation best practices and maintaining existing bootcamp security guidance. + +## Success Metrics + +1. **Content Coverage Completeness** - All three primary files (3.1.4, 3.3.1, 3.3.2) and the quiz file (src/quizzes/chapter-3/3.3/agentic-best-practices-quiz.js) updated with SDD methodology, context engineering principles, and balanced tool coverage (VSCode as primary, Claude Code with equal attention) as specified in functional requirements +2. **Repository Standards Compliance** - All updated markdown files pass `npm run lint` validation and `npm run refresh-front-matter` succeeds without errors +3. **Learning Objective Alignment** - Updated content enables beginners to: understand fundamental AI concepts, apply structured workflows (SDD), manage context windows effectively, select appropriate tools, implement compaction/disclosure, build MCP servers, and work effectively with agentic IDEs +4. **Content Consistency** - Cross-references between sections remain valid, terminology is consistent, and content progression flows logically from foundations (3.1.4) through workflows (3.3.1) to application (3.3.2) +5. **Quiz Content Modernization** - Quiz questions updated to remove Harper Reed workflow references and include new questions on SDD methodology, context engineering, context rot, and intentional compaction +6. **Exercise Transformation** - "VSCode Vibing" exercise successfully restructured to follow complete SDD workflow (spec → tasks → implementation → validation) with context engineering practices integrated +7. **Outdated Content Removed** - "Vibing" language replaced with structured methodology framing, long chat warnings expanded with context rot explanations, and outdated tool recommendations updated + +## Resources and References + +This section lists key resources that should be referenced in the updated documentation, providing participants with authoritative sources for deeper learning. + +### Spec-Driven Development (SDD) + +**Primary Resource:** +- [Liatrio Labs -
