prompt-engineering

A deep, practical guide to engineering reliable LLM prompts — role/context, instructions, few-shot, structured output, chain-of-thought, delimiting untrusted data, injection defense, and evaluation. Includes worked prompts and a runnable output validator.

Overview

Reliable model behavior comes from specificity and structure, not magic words. A good prompt reads like a precise spec: it states the role, the task, the constraints, shows examples, and pins the exact output shape. This package is the deep reference; technique detail lives in references/, worked prompts in examples/, and a runnable output check in scripts/.

Your own Claude Code — no API keys
api-paginationImplement correct, fast API pagination — cursor vs offset trade-offs, opaque cursor encoding, stable sort keys, page-size limits, total-count costs, and consumer-side iteration that survives inserts, deletes, and retries. With runnable cursor checks.app-store-optimizationHow to optimize an app-store listing (ASO) for discovery and conversion — title, subtitle, keywords, screenshots, icon, ratings, and the metadata that drives installs. A deep reference with worked Apple and Google listings and a runnable listing linter.audit-loggingDesign tamper-evident audit logs that satisfy security and compliance — what to record (who/what/when/where/outcome), what to never log (secrets/PII), structured immutable events, hash-chaining for tamper-evidence, retention, and access control. A deep reference with runnable validation.background-jobsDesign background job systems that don't lose or double work — enqueue-after-commit, retry policies with jitter, idempotent handlers, visibility timeouts, priority lanes, scheduled and recurring jobs, worker scaling, and observability for async work. With a runnable retry-policy check.backup-and-recoveryDesign and operate a tested backup and disaster-recovery strategy — the 3-2-1 rule, RPO/RTO targets, full vs incremental vs differential, point-in-time recovery, encryption, offsite/immutable copies, retention, and the restore drills that prove a backup actually works.c4-diagrammingDocument software architecture with the C4 model (Context, Container, Component, Code) as text-based diagrams in version control. Covers the four abstraction levels, notation discipline, when to draw each level (and when to stop), supplementary diagrams, and Mermaid/Structurizr tooling.
