Help developers achieve and maintain deep focus through:
Invoke this skill when:
Evaluate:
Select based on context:
Optimize for focus:
During session:
Best for: General coding, learning, documentation
Method:
1. Choose a task
2. Set timer for 25 minutes
3. Work with full focus (no distractions)
4. Take 5-minute break
5. After 4 pomodoros, take 15-30 minute break
Implementation:
// Pomodoro Timer
const WORK_DURATION = 25 * 60 * 1000; // 25 minutes
const SHORT_BREAK = 5 * 60 * 1000; // 5 minutes
const LONG_BREAK = 30 * 60 * 1000; // 30 minutes
class PomodoroTimer {
private pomodorosCompleted = 0;
async startWorkSession(): Promise<void> {
console.log('š
Pomodoro started - Focus for 25 minutes');
await this.timer(WORK_DURATION);
this.pomodorosCompleted++;
if (this.pomodorosCompleted % 4 === 0) {
console.log('š 4 pomodoros done! Take a 30-minute break');
await this.timer(LONG_BREAK);
} else {
console.log('ā
Pomodoro complete! Take a 5-minute break');
await this.timer(SHORT_BREAK);
}
}
private timer(duration: number): Promise<void> {
return new Promise(resolve => setTimeout(resolve, duration));
}
}
Tips:
Best Use Cases: ā Learning new concepts ā Writing documentation ā Code review ā Bug fixing ā Refactoring
Best for: Full-day planning, multiple projects
Method:
1. Plan day in advance
2. Assign specific time blocks to tasks
3. Include buffer time (10-15%)
4. Schedule breaks and deep work
5. Protect blocked time fiercely
Example Schedule:
08:00-08:30 Morning review & planning
08:30-10:30 Deep Work: Feature implementation
10:30-10:45 Break
10:45-12:00 Code review & PR feedback
12:00-13:00 Lunch
13:00-15:00 Deep Work: Complex algorithm
15:00-15:15 Break
15:15-16:30 Meetings & collaboration
16:30-17:00 Email, Slack, admin tasks
17:00-17:30 End-of-day review & tomorrow planning
Implementation:
interface TimeBlock {
start: string;
end: string;
task: string;
type: 'deep-work' | 'meeting' | 'break' | 'admin';
}
const dailySchedule: TimeBlock[] = [
{ start: '08:30', end: '10:30', task: 'Feature implementation', type: 'deep-work' },
{ start: '10:30', end: '10:45', task: 'Break', type: 'break' },
{ start: '10:45', end: '12:00', task: 'Code review', type: 'admin' },
];
function getCurrentTask(schedule: TimeBlock[]): TimeBlock | null {
const now = new Date();
const currentTime = `${now.getHours()}:${now.getMinutes()}`;
return schedule.find(block =>
block.start <= currentTime && block.end > currentTime
) || null;
}
Tips:
Best for: Complex problems, architecture design, learning
Method:
1. Schedule 2-4 hour uninterrupted blocks
2. Eliminate ALL distractions
3. Single complex task only
4. No context switching
5. Full cognitive engagement
Pre-Session Checklist:
During Session:
Hour 1: Warm-up, context loading
Hour 2: Peak productivity
Hour 3: Maintain momentum
Hour 4: Wrap up, document progress
Tips:
Best Use Cases: ā System architecture design ā Complex algorithm implementation ā Learning new framework deeply ā Major refactoring ā Performance optimization
Best for: Small tasks, preventing task accumulation
Method:
If a task takes less than 2 minutes, do it immediately
Don't add it to your todo list
Examples:
Implementation:
function handleTask(task: Task): void {
if (task.estimatedTime <= 2) {
// Do it now
executeTask(task);
} else {
// Schedule it
addToBacklog(task);
}
}
Tips:
Best for: Similar tasks, administrative work
Method:
1. Group similar tasks together
2. Schedule specific time for batch
3. Process all at once
4. Minimize context switching
Batchable Tasks:
Schedule Example:
Monday 4-5pm: Email & Slack
Tuesday 2-3pm: Code reviews
Wednesday 4-5pm: Documentation
Thursday 2-3pm: Bug triage
Friday 3-5pm: Weekly review & planning
Tips:
Best for: Creative work, complex problem-solving
Prerequisites for Flow:
How to Enter Flow:
1. Choose challenging but achievable task
2. Set clear, specific goal
3. Eliminate all distractions
4. Start with warm-up coding
5. Increase difficulty gradually
6. Maintain for 90-120 minutes
7. Take break before burnout
Flow State Indicators:
Tips:
Eliminate:
# macOS: Block distracting sites
sudo echo "127.0.0.1 facebook.com" >> /etc/hosts
sudo echo "127.0.0.1 twitter.com" >> /etc/hosts
sudo echo "127.0.0.1 reddit.com" >> /etc/hosts
# Use browser extensions:
# - Freedom (block sites/apps)
# - Cold Turkey (distraction blocker)
# - RescueTime (track time)
Communication Boundaries:
Slack: Status "šÆ Deep Work - Back at 2pm"
Email: Auto-responder "Checking email at 12pm and 4pm"
Phone: Do Not Disturb mode
Calendar: Block as "Focus Time"
Optimize:
Focus Music:
Identify Your Peak:
Morning person: 8am-12pm (deep work here)
Evening person: 2pm-6pm (deep work here)
Track for 2 weeks:
- When do you feel most alert?
- When do complex problems feel easier?
- When do you get into flow?
Match Tasks to Energy:
