Personal Operating System

Converts a syllabus or topic list into an evidence-based study plan - material atomized into testable units, a spaced-repetition flashcard schedule with expanding intervals, active recall and Feynman-technique prompts instead of rereading, interleaved weekly sessions, and a practice-testing cadence with an error log. Use when someone says "help me study for this exam", "build me a study schedule", "I keep rereading and forgetting everything", or wants to learn a curriculum efficiently. Do NOT use for acquiring a spoken language specifically - use language-learning instead - or for building everyday habits - use habit-builder instead.

Designs a sustainable daily journaling practice - morning pages, gratitude, intention setting, evening reflection, and weekly review - matched to the user's goal, with copy-paste templates and a rotating prompt library. Use when someone asks "help me start journaling", "give me journal prompts", "I keep abandoning my journal", or "build me a morning pages routine". Do NOT use for building a general habit or streak system - use habit-builder instead; do NOT use for organizing notes and knowledge into a retrieval system - use second-brain instead; for structured end-of-week planning reviews, see weekly-review.

Runs a structured decision process for high-stakes choices - reversibility classification, weighted decision matrices, expected value with explicit probabilities, pre-mortems, second-order thinking, and 10/10/10 - and produces a documented recommendation plus a decision-journal entry. Use when someone asks "should I take this job or stay", "how do I decide between these two paths", "I keep going back and forth on a big decision", or "help me think through whether to relocate". Do NOT use for evaluating a specific large purchase like a house, car, or equipment - use big-purchase-decision instead.

Builds a personalized one-page stress toolkit - mapped triggers, three rehearsed in-the-moment interventions, a recovery menu, and prevention habits - from a week of trigger tracking. Use when someone says "I'm constantly stressed", "I can't switch off after work", "help me deal with anxiety before meetings", or "I keep snapping at people". General wellness education, not medical or mental-health treatment. Do NOT use when the primary complaint is poor sleep - use sleep-optimizer instead; for building a single recurring habit, use habit-builder; for broader life direction and goals, use life-coach.

Turns vague intentions into SMART goals with both lagging targets and controllable leading indicators, then keeps them alive with a 10-minute weekly check-in template, an accountability structure (visible goals, public commitments, partner check-ins), and a quarterly reflection that converts the quarter into lessons. Use when someone says "help me set goals I'll actually stick to", "I set resolutions and abandon them by February", "build me a goal tracking system", or wants a weekly review cadence for personal targets. Do NOT use for company or team objective-setting - use okr-builder instead - or for building daily habits - use habit-builder instead.

Sets up a PARA-based second brain in any notes app (Notion, Obsidian, Apple Notes, Logseq) - Projects, Areas, Resources, Archives buckets, a frictionless universal capture inbox, weekly organizing, wiki-link and map-of-content linking, progressive summarization for recall, and maintenance rituals. Use when someone says "help me set up a second brain", "my notes are a mess and I can never find anything", "how do I organize Obsidian with PARA", or captures ideas but never uses them. Do NOT use for designing the underlying Notion database properties and relations - use notion-database instead - or for a task-management workflow - use gtd-system instead.

Designs a daily schedule that protects deep work - classifies tasks as deep or shallow, places 2-4 focus blocks of 60-120 minutes at peak energy hours, batches shallow work into fixed windows, and defines each session with a goal, definition of done, distraction plan, and first action, plus startup/shutdown rituals and a weekly scorecard. Use when someone says "I can't get any focused work done", "plan my day around deep work", "how do I stop context switching", or wants to defend calendar time for demanding work. Do NOT use for processing an email backlog - use inbox-zero instead - or for a full task-capture system - use gtd-system instead.
