pragmatic-programmer
Apply meta-principles of software craftsmanship: DRY, orthogonality, tracer bullets, and design by contract. Use when the user mentions "best practices", "pragmatic approach", "broken windows", "tracer bullet", "software craftsmanship", "avoid technical debt", "code ownership", or "how do I become a better developer". Also trigger when evaluating build-vs-buy decisions, designing estimation approaches, or choosing between reversible and irreversible architectural decisions. Covers estimation, domain languages, and reversibility. For code-level quality, see clean-code. For refactoring techniques, see refactoring-patterns.

# The Pragmatic Programmer Framework
A systems-level approach to software craftsmanship from Hunt & Thomas' "The Pragmatic Programmer" (20th Anniversary Edition). Apply these meta-principles when designing systems, reviewing architecture, writing code, or advising on engineering culture -- how to think about software, not just how to write it.
## Core Principle
**Care about your craft.** Software development demands continuous learning, disciplined practice, and personal responsibility -- pragmatic programmers think beyond the immediate problem to context, trade-offs, and long-term consequences. Great software comes from great habits: avoid duplication ruthlessly, keep components orthogonal, and treat every line of code as a living asset that must earn its place. The goal is not perfection -- it is systems that are easy to change, easy to understand, and easy to trust.
## Scoring
**Goal: 10/10.** Score against the seven Quick Diagnostic rows: award ~1.4 points per row answered "yes" (7 yes = 10). Then band the result:
- **9-10**: every principle holds -- DRY knowledge, orthogonal layers, a working tracer slice, contracts at boundaries, no broken windows, reversible vendor/DB choices, ranged estimates.
- **5-6**: 1-2 violations that cost real change-effort (e.g. business logic coupled to the DB, single-point estimates).
- **<=3**: pervasive duplication, global state, or accumulated broken windows -- entropy is winning.
