tcp-ip-fundamentals

The networking fundamentals every engineer needs — the layered model and encapsulation, IPv4 addressing/subnetting/CIDR, TCP vs UDP, the 3-way handshake and connection states, ports/sockets, NAT, MTU/fragmentation, and diagnosing issues with ping/traceroute/ss. Deep reference with runnable subnet math.

Overview

Most networking problems become obvious once you know which layer they live at. This skill is the deep reference for the model that runs the internet — the layers, the addressing math, the transport trade-offs, and the diagnostic moves that turn "the network is broken" into a precise, fixable fault. Heavy detail lives in references/; copy-paste material in examples/; runnable subnet math in script

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.
