I. Development Process
1. Brainstorming
Purpose: Transform rough ideas into fully-formed designs through structured questioning.
Core Principle: Ask questions to understand, explore alternatives, present design incrementally for validation.
The 6-Phase Process
- Understanding - Ask ONE question at a time, gather purpose/constraints/criteria
- Exploration - Propose 2-3 approaches with trade-offs
- Design Presentation - Present in 200-300 word sections, validate each
- Design Documentation - Write to
docs/plans/YYYY-MM-DD-<topic>-design.md
- Worktree Setup - Set up isolated workspace (if implementing)
- Planning Handoff - Create implementation plan
Key Principles
- One question at a time - Never overwhelm with multiple questions
- YAGNI ruthlessly - Remove unnecessary features
- Explore alternatives - Always propose 2-3 approaches
- Incremental validation - Validate each section
- Flexible progression - Go backward when needed
When to Use
- Before writing code
- Before creating implementation plans
- When refining rough ideas into designs
2. Writing Plans
Purpose: Create detailed implementation plans from validated designs.
Core Principle: Break work into concrete, verifiable tasks with clear dependencies.
Plan Structure
# Implementation Plan: [Feature Name]
## Overview
- Goal: What we're building
- Context: Why we're building it
- Success criteria: How we know it's done
## Tasks
### Phase 1: Foundation
- [ ] Task 1 (Est: 2h)
- Why: Reason for task
- Acceptance: How to verify
- Dependencies: What must be done first
### Phase 2: Core Features
...
## Risks & Mitigation
- Risk 1: Description → Mitigation strategy
## Testing Strategy
How will we verify this works?
Key Elements
- Task hierarchy - Organize by phases
- Clear acceptance criteria - Know when done
- Dependencies explicit - What blocks what
- Time estimates - Rough sizing
- Risk identification - Surface problems early
3. Executing Plans
Purpose: Systematically execute implementation plans while adapting to discoveries.
Core Principle: Follow the plan, but adapt when reality differs from expectations.
Execution Process
- Start with current task - Follow plan order
- Document deviations - Note when plan differs from reality
- Update as you go - Keep plan synchronized
- Verify completion - Check acceptance criteria
- Mark complete - Update task status
When to Deviate
- Discovery makes approach obsolete
- Dependency breaks assumption
- Better approach becomes clear
- Document WHY you deviated
Tracking Progress
## Progress Log
- [x] Task 1 - Completed 2h (estimated 2h)
- [x] Task 2 - Completed 3h (estimated 2h) - Reason for variance
- [ ] Task 3 - In progress
4. Verification Before Completion
Purpose: Comprehensive verification before marking work complete.
Core Principle: Never mark done until ALL criteria met.
Verification Checklist

II. Testing
5. Test-Driven Development
Purpose: Write tests before implementation to drive design and ensure correctness.
Core Principle: Red → Green → Refactor
The TDD Cycle
-
RED - Write a failing test
- Test describes desired behavior
- Should fail for right reason
- Minimal test to start
-
GREEN - Make it pass
- Simplest code that works
- Don't worry about perfect yet
- Just make test pass
-
REFACTOR - Improve the code
- Now make it clean
- Tests stay green
- Improve design
-
REPEAT - Next test
TDD Principles
- Test first, always - No production code without failing test
- Minimal implementation - Just enough to pass
- Continuous refactoring - Keep code clean
- Tests as specification - Tests document behavior
- Fast feedback - Tests run in seconds
When NOT to TDD
- Exploratory spike (time-boxed)
- Throwaway prototype
- UI layout tweaking
- But - Even these benefit from tests eventually
6. Testing with Subagents
Purpose: Test complex multi-agent or skill-based systems.
Core Principle: Isolate agents, mock dependencies, verify integration.
Testing Strategies
Unit Test Individual Agents
- Test agent logic in isolation
- Mock external dependencies
- Verify single responsibility
Integration Test Agent Coordination
- Test agents working together
- Use test doubles for external systems
- Verify communication protocols
End-to-End Test Full System
- All agents, real dependencies
- Test critical user journeys
- Keep these minimal (slow, brittle)
Agent Testing Patterns
Mock Subagent Responses
def test_coordinator_handles_agent_failure():
mock_agent = Mock(return_value=Error("Agent failed"))
coordinator = Coordinator(agent=mock_agent)
result = coordinator.execute_task()
assert result.handled_gracefully
Test Agent State Management
- Verify state transitions
- Test concurrent access
- Validate state persistence
7. Testing Anti-Patterns
Purpose: Recognize and avoid common testing mistakes.
Core Principle: Tests should be fast, isolated, reliable, and maintainable.
Common Anti-Patterns
1. Fragile Tests
- Problem: Tests break on irrelevant changes
- Solution: Test behavior, not implementation
2. Test Interdependence
- Problem: Tests must run in specific order
- Solution: Each test completely isolated
3. Over-Mocking
- Problem: Mocking everything, testing nothing real
- Solution: Mock external dependencies only
4. Poor Assertions
- Problem:
assert result != null
- Solution:
assert result.value == expected_value
5. Slow Test Suites
- Problem: Tests take minutes to run
- Solution: Fast unit tests, minimal integration tests
6. Testing Private Methods
- Problem: Coupled to implementation
- Solution: Test public interface only
7. Not Testing Edge Cases
- Problem: Only happy path tested
- Solution: Test error cases, boundaries, edge cases
8. Condition-Based Waiting
Purpose: Replace arbitrary timeouts with actual condition checks.
Core Principle: Wait for the condition, not arbitrary time.
The Problem with Sleep
click_button()
time.sleep(5)
assert element_visible()
Solution: Wait for Condition
click_button()
wait_until(lambda: element_visible(), timeout=10, interval=0.1)
assert element_visible()
Implementation Pattern
def wait_until(condition, timeout=10, interval=0.1):
start = time.time()
while time.time() - start < timeout:
if condition():
return True
time.sleep(interval)
raise TimeoutError(f"Condition not met after {timeout}s")
Benefits
- Deterministic - Tests don't randomly fail
- Faster - Don't wait longer than needed
- Clear failure messages - Know what condition failed
9. Test Under Pressure
Purpose: Testing strategies when time is limited.
Core Principle: Risk-based testing - test the most important things first.
Pressure Testing Strategy
Phase 1: Critical Path (Must Have)
- Core functionality
- Happy path for main features
- Data integrity
- Security basics
Phase 2: Important Features (Should Have)
- Secondary features
- Common error cases
- Integration points
Phase 3: Nice to Have (Could Have)
- Edge cases
- Performance testing
- Comprehensive error handling
Time-Saving Techniques
Smoke Tests - Quick "does it work at all?" tests
Parallel Testing - Run tests concurrently
Test Prioritization - Most critical first
Manual Verification - For UI when time-pressed
Defer Comprehensive - Note what's untested
When to Stop
- Critical path covered
- No known blocking bugs
- Risks documented
- Plan for post-release testing
III. Debugging
10. Systematic Debugging
Purpose: Four-phase framework ensuring root cause investigation before fixes.
Core Principle: NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
The Iron Law
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
If you haven't completed Phase 1, you cannot propose fixes.
The Four Phases
Phase 1: Root Cause Investigation
- Read error messages carefully - completely
- Reproduce consistently - exact steps
- Check recent changes - what changed?
- Gather evidence in multi-component systems:
- Log data entering/exiting each component
- Verify config propagation
- Check state at each layer
- Trace data flow - where does bad value originate?
Phase 2: Pattern Analysis
- Find working examples - what works that's similar?
- Compare against references - read completely
- Identify differences - list every difference
- Understand dependencies - what does this need?
Phase 3: Hypothesis and Testing
- Form single hypothesis - "I think X because Y"
- Test minimally - smallest possible change
- Verify before continuing - did it work?
- When you don't know - say so, ask for help
Phase 4: Implementation
- Create failing test case - simplest reproduction
- Implement single fix - address root cause
- Verify fix - test passes, no regressions
- If fix doesn't work - Return to Phase 1
- If 3+ fixes failed - Question the architecture
Red Flags - STOP
- "Quick fix for now, investigate later"
- "Just try changing X and see"
- "Add multiple changes, run tests"
- "Skip the test, I'll manually verify"
- "I don't fully understand but this might work"
- "One more fix attempt" (after 2+ failures)
After 3 Failed Fixes
STOP and question fundamentals:
- Is this pattern fundamentally sound?
- Should we refactor architecture vs. continue fixing symptoms?
- Discuss with team before attempting more fixes
11. Root Cause Tracing
Purpose: Trace issues backward through call stack to find their origin.
Core Principle: Fix at source, not at symptom.
Backward Tracing Technique
- Start at error location - Where does it fail?
- Trace back one step - What called this with bad value?
- Continue upward - Keep tracing to source
- Find the origin - Where did bad value start?
- Fix at source - Not at symptom location
Example Trace
Error: Invalid user ID "-1"
↑ renderUserProfile(userId=-1)
↑ getUserProfile(userId=-1)
↑ processRequest(params={userId: "-1"})
↑ parseQueryString("?userId=-1") ← SOURCE OF PROBLEM
Fix: Add validation in parseQueryString, not in renderUserProfile
Tracing Patterns
Bad Value Propagation
- Value starts bad → Fix at origin
- Value becomes bad → Fix at transformation
Missing Validation
- Data crosses trust boundary → Add validation there
- Internal function assumes valid → Validate at entry
State Corruption
- Who last modified state?
- What sequence led to corruption?
- Fix the sequence, not the symptom
12. When Stuck
Purpose: Strategies to identify why you're stuck and get unstuck.
Core Principle: Recognize the pattern of being stuck, then change approach.
Signs You're Stuck
- Trying same thing repeatedly
- Making no progress for >30 minutes
- Feeling frustrated or confused
- Not sure what to try next
- Each attempt reveals new problem
Unsticking Strategies
1. Take a Break
- Step away for 5-10 minutes
- Fresh perspective often helps
- Don't force it
2. Explain the Problem
- Rubber duck debugging
- Write it down
- Tell someone else
- Often solution appears while explaining
3. Question Assumptions
- What am I assuming is true?
- Is that assumption correct?
- What if the opposite were true?
4. Simplify
- Remove complexity
- Test smallest possible case
- Build up from working baseline
5. Change Approach
- Try different angle
- Different tool
- Different strategy
6. Ask for Help
- Don't suffer alone
- Someone else's perspective helps
- Describe what you've tried
When to Ask for Help
- After 3 failed attempts
- When fundamentally confused
- When time-critical
- Earlier is better than later
IV. Code Review
13. Code Reviewer
Purpose: Provide valuable, constructive code reviews.
Core Principle: Review for correctness first, then everything else.
Review Priority Order
- Correctness - Does it work?
- Security - Any vulnerabilities?
- Performance - Any obvious issues?
- Maintainability - Can others understand/modify?
- Style - Follows conventions?
Review Checklist
Functionality
- Does code do what PR says?
- Are edge cases handled?
- Are error cases handled?
Security
- Input validation?
- SQL injection risks?
- XSS vulnerabilities?
- Authentication/authorization?
Testing
- Are there tests?
- Do tests cover important cases?
- Are tests clear and maintainable?
Design
- Is design appropriate?
- Too complex or too simple?
- Fits with existing architecture?
Readability
- Can you understand it?
- Are names clear?
- Is flow logical?
Giving Feedback
Be Constructive
- Explain WHY something is a problem
- Suggest alternatives
- Balance critique with praise
Be Specific
# Bad
"This is confusing"
# Good
"The variable name 'x' doesn't indicate what it represents. Consider 'userId' instead."
Distinguish Blocking vs. Non-Blocking
- Blocking: Must fix (bugs, security)
- Non-blocking: Suggestions (style, optimization)
14. Requesting Reviews
Purpose: Prepare code reviews that reviewers can act on quickly.
Core Principle: Make reviewer's job easy.
Before Requesting Review
Self-Review First
- Read your own code
- Check for obvious issues
- Run tests locally
- Review the diff
Make it Reviewable
- Small, focused changes
- One logical change per PR
- Clear title and description
PR Description Template
## What
Brief description of change
## Why
Why is this change needed?
## How
How does it work?
## Testing
- [ ] Unit tests added/updated
- [ ] Manual testing completed
- [ ] No regressions
## Screenshots
(if UI change)
## Notes for Reviewer
Anything tricky or unusual?
Size Guidelines
- Small: < 200 lines - Easy to review
- Medium: 200-500 lines - Takes focus
- Large: 500+ lines - Consider breaking up
15. Receiving Reviews
Purpose: Respond to code review feedback constructively.
Core Principle: Assume good intent, learn from feedback.
Responding to Feedback
1. Assume Good Intent
- Reviewer wants to help
- Not personal attack
- Opportunity to learn
2. Ask Clarifying Questions
"Could you elaborate on why this is a concern?"
"What alternative approach would you suggest?"
3. Defend When Needed
- Explain reasoning objectively
- Provide context reviewer might lack
- Be open to being wrong
4. Thank Reviewers
- Appreciate their time
- Acknowledge good catches
- Build positive relationship
Handling Different Feedback Types
Bugs Found
- "Good catch! I'll fix that."
- Fix and re-request review
Design Disagreements
- Discuss trade-offs objectively
- May need to escalate if can't agree
- Document decision
Style Nitpicks
- If convention exists: follow it
- If no convention: discuss with team
- Don't fight over preferences
V. Git & Workflow
16. Using Git Worktrees
Purpose: Work on multiple branches simultaneously without switching.
Core Principle: Separate working directories per branch, no switching overhead.
What Are Worktrees?
Git worktrees let you check out multiple branches into different directories simultaneously.
project/
├── main/ (main branch)
├── feature-a/ (feature-a branch)
└── feature-b/ (feature-b branch)
Creating a Worktree
git worktree add ../project-feature-a feature-a
cd ../project-feature-a
Benefits
- No branch switching - Open multiple in IDE
- Parallel testing - Test different branches simultaneously
- Comparison - Easy to compare branches
- No stashing - Work-in-progress stays in place
Worktree Workflow
git worktree list
git worktree add path/to/dir branch-name
git worktree remove path/to/dir
rm -rf path/to/dir
git worktree prune
Safety Checks
Before creating worktree:
17. Finishing Branches
Purpose: Properly complete and merge development branches.
Core Principle: Clean history, verified work, proper cleanup.
Branch Completion Checklist
Before Merging
Merge Strategy
Option 1: Merge Commit
git checkout main
git merge --no-ff feature-branch
- Preserves branch history
- Clear feature boundary
- Good for feature branches
Option 2: Rebase
git checkout feature-branch
git rebase main
git checkout main
git merge --ff-only feature-branch
- Linear history
- Cleaner log
- Good for small changes
Option 3: Squash
git checkout main
git merge --squash feature-branch
git commit -m "Feature: description"
- Single commit
- Clean history
- Good for many small commits
After Merging

Verify installation:
python -c "import package; print(package.__version__)"
---
## 19. Writing Clearly and Concisely
**Purpose:** Apply timeless rules for clear, strong, professional writing.
**Core Principle:** Omit needless words, use active voice, be specific.
### Strunk's Key Rules
**1. Use Active Voice**
Passive
The bug was fixed by the developer.
Active
The developer fixed the bug.
**2. Omit Needless Words**
Wordy
Due to the fact that the system was experiencing issues...
Concise
Because the system had issues...
**3. Use Specific, Concrete Language**
Vague
The system is slow.
Specific
The API responds in 5 seconds (target: <1 second).
**4. Avoid Qualifiers**
Weak
The code is somewhat complex.
Strong
The code is complex.
**5. Parallel Construction**
Inconsistent
The function should validate input, processing the data, and return results.
Parallel
The function should validate input, process data, and return results.
### Quick Improvement Checklist
- [ ] Remove "very", "really", "quite"
- [ ] Change passive to active voice
- [ ] Replace "there is/are" constructions
- [ ] Make subjects and verbs close together
- [ ] Use specific nouns, strong verbs
---
## 20. Elements of Style
**Purpose:** Classical writing principles from Strunk & White.
**Core Principle:** Elementary rules create clear, vigorous prose.
### Elementary Rules of Usage
1. **Form possessive singular** - Add 's (Charles's)
2. **In a series, use comma** - red, white, and blue
3. **Enclose parenthetic expressions** - Use commas
4. **Place a comma before** - conjunction in compound sentence
5. **Do not join independent clauses** - Use semicolon
### Elementary Principles of Composition
1. **Choose a suitable design** - Plan before writing
2. **Make the paragraph the unit** - One topic per paragraph
3. **Use active voice** - Subject acts
4. **Put statements in positive form** - Say what is, not isn't
5. **Use definite, specific, concrete language** - Precision
6. **Omit needless words** - Brevity
7. **Avoid succession of loose sentences** - Vary structure
8. **Express coordinate ideas in similar form** - Parallel
9. **Keep related words together** - Proximity
10. **In summaries, same tense** - Consistency
11. **Place emphatic words at the end** - Power position
### Words Often Misused
- **affect/effect** - Affect = verb, Effect = noun
- **comprise/compose** - Whole comprises parts
- **different from/than** - Different from (not than)
- **less/fewer** - Less (mass), Fewer (count)
- **which/that** - That (restrictive), Which (non-restrictive)
---
# VII. Architecture & Design
## 21. Defense in Depth
**Purpose:** Implement multiple layers of validation and protection.
**Core Principle:** Never rely on a single layer of defense.
### Layered Validation
**Layer 1: Input Validation**
```python
def process_user_input(data):
# First line of defense
if not isinstance(data, dict):
raise ValueError("Invalid input type")
if "id" not in data:
raise ValueError("Missing required field: id")
Layer 2: Business Logic Validation
def update_user(user_id, changes):
user = get_user(user_id)
if not user:
raise NotFound("User not found")
if not has_permission(current_user, user):
raise Forbidden("No permission to update")
Layer 3: Database Constraints
CREATE TABLE users (
id INT PRIMARY KEY,
email VARCHAR(255) NOT NULL UNIQUE,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
Defense Layers
- Client-side - UX, not security
- API Gateway - Rate limiting, authentication
- Application - Business logic validation
- Database - Constraints, transactions
- Infrastructure - Firewalls, network isolation
Principles
- Fail securely - Default to deny
- Validate explicitly - Never assume
- Principle of least privilege - Minimum necessary access
- Defense in depth - Multiple layers
22. Subagent-Driven Development
Purpose: Coordinate development using autonomous sub-agents.
Core Principle: Independent agents with clear interfaces and responsibilities.
Agent Decomposition
Identify Agents
- Each handles one responsibility
- Clear input/output contract
- Can operate independently
- Minimal shared state
Example Decomposition
Project: E-commerce System
Agents:
- ProductCatalogAgent - Manages products
- OrderProcessingAgent - Handles orders
- PaymentAgent - Processes payments
- NotificationAgent - Sends notifications
Agent Coordination Patterns
1. Message Passing
class OrderAgent:
async def process_order(self, order):
await self.send_message(
PaymentAgent,
"process_payment",
payment_info
)
2. Event Broadcasting
class OrderAgent:
async def complete_order(self, order):
await self.emit_event("order_completed", order_id)
3. Shared Queue
task_queue = Queue()
agents = [Agent() for _ in range(5)]
for agent in agents:
agent.start_processing(task_queue)
Agent Testing
- Test each agent in isolation
- Mock inter-agent communication
- Test coordination separately
- Integration test critical paths
23. Dispatching Parallel Agents
Purpose: Launch and manage parallel agents effectively.
Core Principle: Coordinate work distribution, track progress, handle failures.
Parallel Dispatch Pattern
async def dispatch_parallel_agents(tasks):
results = []
agents = [Agent(task) for task in tasks]
futures = [agent.execute() for agent in agents]
results = await asyncio.gather(*futures, return_exceptions=True)
for task, result in zip(tasks, results):
if isinstance(result, Exception):
handle_failure(task, result)
else:
handle_success(task, result)
return results
Work Distribution Strategies
Round Robin
- Even distribution
- Simple
- No load balancing
Load-Based
- Assign to least-loaded agent
- Better utilization
- Requires monitoring
Task-Based
- Agents specialized for task type
- Efficient
- More complex
Progress Tracking
class ProgressTracker:
def __init__(self, total_tasks):
self.total = total_tasks
self.completed = 0
self.failed = 0
def task_completed(self):
self.completed += 1
print(f"Progress: {self.completed}/{self.total}")
def task_failed(self, error):
self.failed += 1
log_error(error)
24. Collision Zone Thinking
Purpose: Identify where different parts of system might conflict.
Core Principle: Find shared resources and concurrent access points.
Finding Collision Zones
Shared State
class Counter:
count = 0
def increment(self):
self.count += 1
Concurrent Database Access
UPDATE accounts SET balance = balance - 100 WHERE id = 1;
File System
with open("shared.txt", "w") as f:
f.write("data")
Collision Analysis Framework
-
Identify shared resources
- Memory
- Files
- Database records
- Network connections
-
Map access patterns
- Who accesses what?
- When do they access it?
- Read or write?
-
Find overlaps
- Simultaneous writes = collision
- Write during read = collision
- Simultaneous reads = OK (usually)
-
Design resolution
- Locking
- Queuing
- Partitioning
- Eventual consistency
Collision Resolution Strategies
Pessimistic Locking
with lock:
value = shared_resource.read()
shared_resource.write(value + 1)
Optimistic Locking
while True:
version = shared_resource.version
value = shared_resource.read()
if shared_resource.write_if_version(value + 1, version):
break
25. Preserving Productive Tensions
Purpose: Maintain healthy tension between competing design concerns.
Core Principle: Don't resolve tensions, balance them.
Productive Tensions
Speed vs. Quality
- Speed pushes for shipping
- Quality pushes for perfection
- Balance: Ship quality that's good enough
Flexibility vs. Simplicity
- Flexibility enables future changes
- Simplicity makes current work easier
- Balance: Flexible where needed, simple elsewhere
Abstraction vs. Concreteness
- Abstraction enables reuse
- Concreteness is clear
- Balance: Abstract common patterns, concrete specifics
Perfect vs. Good Enough
- Perfect takes forever
- Good enough ships
- Balance: Perfect critical paths, good enough elsewhere
Balancing Tensions
Don't Pick Sides
- Both perspectives have value
- Tension is productive
- Resolution kills creativity
Make Trade-offs Explicit
## Decision: How abstract should this API be?
Flexibility Argument:
- Future use cases unknown
- Extensibility valuable
Simplicity Argument:
- Current use case is clear
- Complexity has cost
Decision: Abstract the data model, concrete the operations.
Rationale: Data changes more than operations.
Revisit Periodically
- Tensions shift over time
- Rebalance as context changes
26. Simplification Cascades
Purpose: Progressively simplify systems through cascading improvements.
Core Principle: Simplifying one layer enables simplification of dependent layers.
The Cascade Effect
Complex database schema
↓ Simplify schema
Simpler queries
↓ Simpler queries enable
Simpler business logic
↓ Simpler logic enables
Simpler API
↓ Simpler API enables
Simpler client code
Simplification Process
1. Identify Complexity Source
- Where does complexity originate?
- What drives the complexity?
- Can we address the source?
2. Simplify One Layer
- Start at source of complexity
- Make ONE simplification
- Don't try to fix everything
3. Observe Cascade
- What else becomes simpler?
- What constraints are relaxed?
- What opportunities appear?
4. Simplify Next Layer
- Use relaxed constraints
- Simplify dependent layer
- Repeat
5. Stop When Stable
- No more obvious simplifications
- System feels "right"
- Further simplification adds complexity
Example Cascade
Before:
class OrderProcessor:
states = [PENDING, VALIDATING, VALIDATED, CHECKING_INVENTORY, ...]
Simplification 1: Reduce states
class OrderProcessor:
states = [PENDING, PROCESSING, COMPLETED, FAILED, CANCELLED]
Cascade Effect: State machine simpler → transitions simpler → testing simpler → monitoring simpler
VIII. Meta-Skills
27. Using Skills
Purpose: Apply skills effectively in your workflow.
Core Principle: Skills are tools - know when and how to use them.
When to Invoke Skills
Explicit Triggers
- Problem matches skill description
- Task requires skill's workflow
- User explicitly references skill
Implicit Triggers
- Patterns indicate skill would help
- Quality would improve with skill
- Efficiency would increase with skill
Announcing Skill Usage
I'm using the [skill-name] skill to [accomplish goal].
Why announce?
- Transparency
- Educational
- Sets expectations
- Enables feedback
Combining Skills
Sequential:
1. brainstorming → design
2. writing-plans → implementation plan
3. test-driven-development → implementation
4. code-reviewer → quality check
Parallel:
- systematic-debugging (find bug)
- root-cause-tracing (trace origin)
- Used together for thorough debugging
Skill Selection
Ask:
- What problem am I solving?
- Which skills address this problem?
- Which is most appropriate?
- Do I need multiple skills?
28. Using Superpowers
Purpose: Advanced techniques for skill composition and mastery.
Core Principle: Skills compose, adapt, and extend.
Skill Chaining
Input → Skill A → Intermediate → Skill B → Output
Example:
Rough idea → brainstorming → Design
Design → writing-plans → Implementation Plan
Plan → executing-plans → Working Code
Skill Adaptation
Adapt skills to context:
- Adjust level of detail
- Modify process steps
- Combine with domain knowledge
Example:
test-driven-development (standard)
+ mobile app context
= TDD with platform-specific considerations
Context Switching

IX. Thinking & Analysis
32. Meta-Pattern Recognition
Purpose: Recognize and apply patterns that transcend specific contexts.
Core Principle: Patterns repeat across domains - learn to see them.
Cross-Domain Pattern Mapping
Pattern: Caching
- Computers: Store computed results
- Business: Inventory management
- Biology: Memory formation
- Architecture: Prefabrication
Pattern: Queue
- Computers: Message queue
- Business: Customer service line
- Traffic: Road congestion
- Manufacturing: Work-in-progress
Finding Meta-Patterns
1. Abstract the Structure
- Remove domain-specific details
- What's the core pattern?
- What are the key relationships?
2. Map to Other Domains
- Where else does this structure appear?
- Different context, same pattern?
- What's similar, what's different?
3. Transfer Insights
- Solution from one domain → another
- Avoid reinventing the wheel
- Adapt, don't copy blindly
Pattern Catalog
Common Meta-Patterns:
- Layering - Abstraction levels
- Pipeline - Sequential transformation
- Feedback loops - Output → Input
- Caching - Store for reuse
- Partitioning - Divide and conquer
- Replication - Redundancy for reliability
33. Inversion Exercise
Purpose: Think backwards from desired outcome to find solution path.
Core Principle: Start with the end, work backwards to the beginning.
The Inversion Process
1. Define End State
- What does success look like?
- Be specific and concrete
- Measurable if possible
2. Work Backwards
- What must be true immediately before?
- And before that?
- Continue until reaching current state
3. Identify Prerequisites
- What must exist at each step?
- What must be true?
- What must be done?
4. Remove Obstacles
- What blocks each step?
- How to remove blockers?
- What dependencies?
5. Reverse for Forward Plan
- Now you have the path
- Execute in reverse order
- Each step enables next
Example Inversion
Goal: Ship product feature
Backwards:
Feature in production
← Must pass deployment
← Must pass QA
← Must be code complete
← Must have passing tests
← Must have design
← Must have requirements
Forward Plan: Requirements → Design → Tests → Code → QA → Deploy
When to Use Inversion
- Stuck moving forward
- Complex problem
- Many dependencies
- Unclear path
- Need to identify prerequisites
34. Tracing Knowledge Lineages
Purpose: Track how ideas and knowledge evolve over time.
Core Principle: Ideas have origins, transformations, and influences.
Knowledge Lineage Mapping
1. Identify Source
- Where did this idea originate?
- Who first articulated it?
- What was the context?
2. Track Transformations
- How did it change?
- Who modified it?
- What was added/removed?
3. Map Influences
- What influenced this idea?
- What did it influence?
- Citation chains
4. Document Provenance
- Maintain the lineage
- Credit sources
- Show evolution
Example Lineage
Structured Programming (Dijkstra, 1968)
↓ influenced
Object-Oriented Programming (1970s)
↓ influenced
Design Patterns (GoF, 1994)
↓ influenced
Modern Software Architecture (2000s)
Why Track Lineages?
- Credit sources - Attribution
- Understand evolution - Context
- Avoid reinvention - Build on past
- Identify gaps - Missing links
35. Search Agent
Purpose: Systematic approach to searching and information gathering.
Core Principle: Good search is methodical, not random.
Search Process
1. Define Search Goal
- What exactly do I need?
- How will I know when I find it?
- What's good enough?
2. Formulate Query
- Key terms
- Boolean operators (AND, OR, NOT)
- Phrases in quotes
- Filters (date, type, domain)
3. Execute Search
- Try query
- Scan results
- Refine if needed
4. Evaluate Results
- Relevant to goal?
- Authoritative source?
- Current information?
- Comprehensive enough?
5. Iterate
- Not good enough? Refine query
- New terms discovered? Add them
- Too many results? Add filters
- Too few results? Broaden search
Search Strategies
Broad to Narrow
- Start general
- Add specificity
- Refine until good results
Multiple Sources
- Don't rely on one source
- Cross-reference
- Verify claims
Source Evaluation
- Authority
- Currency
- Relevance
- Bias
36. Remembering Conversations
Purpose: Techniques for retaining context across conversations.
Core Principle: External memory supplements internal memory.
Context Retention Techniques
1. Take Notes
- Key decisions
