Problem: A store has 15 apples. They sell 60% in the morning and
half of what's left in the afternoon. How many remain?

Please solve this step-by-step:
1. Calculate morning sales
2. Calculate remaining after morning
3. Calculate afternoon sales
4. Calculate final remaining

Question: What are the security implications of storing JWTs
in localStorage?

Let's think step by step:

Analyze this code for issues. Structure your response as:

<analysis>
  <security_issues>
    <issue severity="high|medium|low">
      <description>What's wrong</description>
      <location>File and line number</location>
      <fix>How to fix it</fix>

Stage 1: "Analyze this codebase structure and list the main components"
[Get response]

Stage 2: "Now, for the authentication component you identified,
show me the security review"
[Get response]

Stage 3: "Based on that review, generate fixes for the high-severity issues"

ROLE: Senior TypeScript Developer
TASK: Implement user authentication service
CONSTRAINTS:
- Use JWT with refresh tokens
- TypeScript with strict mode
- Include comprehensive error handling
- Follow SOLID principles
OUTPUT: Complete TypeScript class with JSDoc comments
REASONING_EFFORT: high (for complex business logic)

"Implement this feature step-by-step, asking for confirmation
before each major decision"

OR

"Complete this task end-to-end without asking for guidance.
Persist until fully handled."

"Provide a concise implementation (under 100 lines) focusing
only on core functionality"

Think through this architecture decision step by step:
1. First, identify the requirements
2. Then, list possible approaches
3. Evaluate trade-offs for each
4. Make a recommendation with reasoning

BAD: "Make the response professional"
GOOD: "Use formal business language, avoid contractions,
address the user as 'you', keep sentences under 20 words"

"Write some code for user authentication"

"Write a TypeScript class called AuthService that:
- Accepts email/password credentials
- Validates against a User repository
- Returns a JWT token on success
- Throws AuthenticationError on failure
- Includes comprehensive JSDoc comments
- Follows dependency injection pattern"

"Convert these variable names to camelCase"

"Convert these variable names to camelCase:

user_name → userName
total_count → totalCount
is_active → isActive
