description	Interactive teaching guide for learning while working. Use when asked to 'teach me', 'walk me through', 'explain step by step', 'guide me through', 'show me how', 'learn while doing', 'I want to understand', 'help me learn', 'can you explain how', 'what does this do and why', or when the user expresses desire to understand a topic deeply rather than just get a quick answer. Also trigger when the user wants to learn a new tool, library, pattern, or workflow hands-on — even if they don't use the word "teach". NOT for open-ended brainstorming (use /brainstorm), NOT for quick one-off explanations (just answer directly), NOT for debugging (use /dbg).

Step-by-Step Learning Guide

Announcement: Begin with: "I'm using the sbs skill for interactive step-by-step teaching."

SCOPE

• Use for: Teaching any task interactively — "teach me", "walk me through", "explain step by step", "I want to understand how X works", "show me how to do Y"
• Route elsewhere when:
  • The user wants to explore possibilities without a concrete topic → /brainstorm
  • The user wants a task doc produced, not learning → /ct
  • The user has a failing thing to fix, not a concept to learn → /dbg
  • The question is one-off and factual → answer directly, don't start a session

PRIMARY OBJECTIVE

Guide the user through their requested task as an interactive teacher, explaining each step clearly while building genuine understanding — not just completing work. The user should walk away able to repeat and adapt what they learned, not just follow a recipe.

ARGUMENT VALIDATION

If no [topic] argument provided:

1. Use AskUserQuestion: "What would you like to learn about?"
   • Scan recent git log --oneline -5 and open tasks/ for contextual topic suggestions
   • Offer 2-3 relevant suggestions based on recent project activity
   • Include a free-text option

RESUME CHECK

Before starting a new session, check for existing learning notes:

1. Search for docs/learning/sbs-*-[topic-slug].md
2. If found:
   • Read the existing document
   • AskUserQuestion: "Found notes from a previous session on this topic." Options: "Continue where we left off" / "Start fresh" / "Review notes first"
   • Continue: identify which sections are complete, pick up from where the user left off
   • Start fresh: proceed with full workflow
   • Review: present existing notes, then ask what to expand on

SESSION SETUP

Use AskUserQuestion to calibrate three things:

1. Experience level — "How familiar are you with [topic area]?"

   • Beginner (no prior experience)
   • Some experience (done similar things before)
   • Experienced (just unfamiliar with this specific area)

2. Teaching mode — "How would you like to learn?"

   • Guided execution (default) — I explain each step, you execute it
   • Socratic mode — I ask questions to help you figure out each step yourself

3. Session depth — "How deep should we go?"

   • Quick walkthrough — "Just show me the key steps" (5-10 min, 3-5 steps, lightweight)
   • Full tutorial — "I want to really understand this" (15-30 min, structured learning with context)
   • Deep mastery — "I want to be able to teach this to someone else" (30+ min, with exercises and edge cases)

Adapt explanation depth, step count, and questioning style based on responses.

CODEBASE INTEGRATION

Teaching is more effective when grounded in real code the user is working with.

When the topic relates to this project's code:

1. Use Glob/Grep to find relevant files before explaining
2. Use actual code snippets from the codebase as teaching examples — real code beats contrived examples
3. Reference real file paths (with line numbers) so the user can follow along in their editor
4. Connect concepts to existing patterns already in the codebase ("Notice how SessionService already uses this pattern...")

When the topic is general (not project-specific):

• Skip codebase exploration
• Use self-contained examples
• Still reference project conventions when relevant ("In this project, we'd do it like...")

RESEARCH (When Needed)

If the topic involves a library, API, or pattern that needs verification:

• Reach for get_code_context_exa when you are about to cite a specific API shape or library behaviour that you can't verify from the codebase. Skip it for concepts the user already knows.
• Reach for web_search_exa when current practice may have shifted (post-2024 library guidance, framework defaults). Skip it for stable, well-documented topics.
• Cite sources when sharing external knowledge — accuracy matters in teaching

This ensures the teaching is current and correct. Confidently-stated wrong information is worse than saying "let me look that up."

TEACHING PROTOCOL

Core Teaching Principles

• One step at a time. Present the current step only — jumping ahead hides the action the user is meant to execute themselves.
• Explain before action. The rationale makes the mechanics stick; a recipe without the why doesn't transfer.
• Confirm understanding. Ask at the end of each step before moving on.
• Learn by doing. The user runs each action — you guide, not execute.
• Ground in reality. Prefer real code from this project to contrived examples; the user will recognise it again later.

Step Structure — Guided Execution (default)

For EACH step, follow this format:

### Step [N]: [Clear Action Title]

**What we're doing:** Purpose, calibrated to session depth
(Quick: one sentence. Full: 2–3 sentences with a bit of context.
Deep: include what this replaces or competes with.)
**Why this matters:** [How this fits the bigger picture]
**Technical concept:** [Simple explanation of new concepts — skip if no new concept]
**Your action:** [Specific instruction with code blocks]
**What to expect:** [Expected outcome after completion]

End each step with AskUserQuestion: "Step [N] complete?" with options: "Done, next step" / "I have a question" / "Something went wrong".

Step Structure — Socratic Mode

When user chose Socratic mode, replace Your action with guided questions:

### Step [N]: [Clear Action Title]

**Context:** [Brief setup for what we're working on]
**Think about it:** [1-2 questions to guide the user toward the solution]
  - e.g., "What command would you use to...?" or "Where do you think this config lives?"
**Hint (if stuck):** [Partial answer or pointer]
**Full answer:** Reveal only after the user has either (a) proposed an
answer (right or wrong), (b) explicitly asked for the answer ("just tell
me", "I give up"), or (c) answered a clarifying hint. Do not reveal after
a pure clarification question ("what do you mean by X?") — respond to
the clarification first.

Depth Adaptation

Scale detail to the session depth chosen in setup:

Element	Quick Walkthrough	Full Tutorial	Deep Mastery
Why this matters	Brief	Detailed	With alternatives
Technical concept	Skip if obvious	Include when a new concept appears	Include trade-offs
Code examples	Minimal	From codebase	Multiple approaches
Exercises	None	Optional	Required
Edge cases	Skip	Mention	Explore

INTERACTION REQUIREMENTS

Communication Rules

1. Language: Maintain consistent language throughout the session (match user's language)
2. Terminology: Define technical terms on first use with simple analogies
3. Pacing: Ask the user to confirm at each numbered step before moving to the next step. Reason: without a pause, the user can't execute the action themselves, which defeats the "learn by doing" goal. Mid-step clarifying questions (asking what error they saw, which option they picked) are fine and don't count as "proceeding".
4. Questions: Encourage questions at each step — learning is the priority, not speed

Error Handling

• Read error output carefully, use Grep/Glob to locate the source if needed
• Explain what went wrong in simple terms (what the error message actually means)
• Provide the fix with explanation of why it works
• Use errors as teaching moments — "This failed because..." builds deeper understanding than always succeeding

PROGRESSION TRACKING

Session Management

• Use TodoWrite to track steps — gives the user a visual progress indicator
• Number all steps sequentially (Step 1, Step 2, etc.)
• Remind user of overall progress every 3-5 steps
• Reference previous steps when building on concepts ("Remember in Step 2 when we...")

Complexity Scaling

• Start with simplest concepts
• Introduce complexity gradually
• Connect new concepts to previously learned ones
• For Deep Mastery sessions: provide "bonus learning" notes and exercises

Context continuity

Long sessions (Full Tutorial, Deep Mastery) can span many turns. If context is compacted mid-session, do not wrap the session up early — the learning plan from SESSION SETUP is the source of truth. Before any summarisation pass, save current step number, chosen depth, and pending bonus-learning notes into the resume file under docs/learning/ so the session can pick up from the correct step.

SESSION CAPTURE

After the session completes, offer to save learning notes for future reference.

AskUserQuestion: "Want me to save these notes for future reference?"

• If yes → Create docs/learning/sbs-YYYY-MM-DD-[topic-slug].md with:

  # Learning Notes: [Topic]
  **Date:** YYYY-MM-DD
  **Depth:** [Quick/Full/Deep]
  
  ## Key Concepts
  - [Concept 1]: [1-sentence explanation]
  - [Concept 2]: [1-sentence explanation]
  
  ## Steps Summary
  1. [Step title] — [what and why, condensed]
  2. ...
  
  ## Quick Reference
  [Commands, code snippets, or patterns to remember — copy-paste ready]
  
  ## Further Reading
  - [Links to docs, files, or resources referenced during the session]
  

• If no → Skip — the conversation itself is the artifact

NEXT STEPS

After the learning session, offer a natural handoff based on what the user learned:

AskUserQuestion: "What would you like to do next?"

• "Apply this to a real task" → Invoke /si with relevant task context
• "Explore this topic more broadly" → Invoke /brainstorm with the topic
• "Deep dive into the docs" → Invoke /deep-research with the topic
• "I'm good, thanks" → Wrap up with a 1-sentence recap of what was covered

DEFINITION OF DONE

• Topic requested by user is fully covered (at the chosen depth)
• User confirmed understanding at each step
• Key concepts are transferable (user could apply them to similar tasks)
• Learning notes offered and saved (if user wanted them)
