Use whenever creating, renaming, or editing any file under docs/ in this repo, or when asked to compile/build the book PDF. Enforces the exact .mdx frontmatter, ID scheme, and heading-depth rules required by the go-pretty-pdf tool (https://github.com/sazardev/go-pretty-pdf) so the whole book keeps compiling.

Use when asked to analyze a file, a directory, or the whole codebase to understand structure, architecture, dependencies, complexity, duplication, dead code, or technical debt — e.g. "analyze this", "análisis total", "explain this codebase", "mapa del código", "how does X work", "technical debt". Produces a complete…

Use when asked to audit or harden security in this repo — e.g. "security audit", "auditoría de seguridad", "revisa la seguridad", "is this secure", "hardening", "vulnerabilities". Audits code, config, workflows, and secrets exposure. Covers injection, secrets, TLS, untrusted input, dependency risk, and CI supply-chain…
Skill Claude CodeCodex
Use when reviewing the structure, ordering, coherence, and narrative flow of the book as a whole or across chapters. Checks chapter sequencing against the ID scheme, cross-references and forward hooks between chapters, README/index link integrity, exercise-to-chapter pairing, duplicate or contradictory content, and…

Use when writing, expanding, rewriting, or drafting any chapter (.mdx) or Go exercise for this book. Encodes the authorial voice, the mdx-pdf-format rules, the ID/naming scheme, the zero-emoji rule, chapter/exercise pairing, and the "theory first, then code" pedagogy so new or edited content reads like the rest of the…
Skill Claude CodeCodex
Use when brainstorming, evaluating ideas, designing architectures, writing technical plans, or choosing between approaches — e.g. "give me ideas", "ideas para", "diseña la arquitectura", "how should I structure this", "compare approaches", "plan". Turns vague ideas into concrete, prioritized, buildable designs with…

Use when proofreading, copy-editing, or verifying English in any docs//.mdx chapter or code comment in this repo. Catches grammar, punctuation, spelling, syntax, article/tense/agreement errors, wordiness, tone drift, and style inconsistencies, and rewrites text in the book's confident second-person voice without…
Skill Claude CodeCodex
Use when reviewing, writing, or debugging Go code under exercises/part2/ (and matching embedded code in docs/part2//.mdx). Thinks hard about correctness, idiomatic Go, error handling, resource cleanup, concurrency, and — crucially — what the tests would catch: edge cases, races, leaks, timeouts, and port conflicts.…
Skill Claude CodeCodex
Use when asked to map or analyze flows, pipelines, processes, or sequences of events in this repo — e.g. "mapa el flujo", "flow", "pipeline", "ciclo de vida", "trace the request", "how does the build/release flow work", "diagrama del flujo". Maps data flows, request lifecycles, CI/CD pipelines, and state transitions…

Use when reviewing, debugging, or improving frontend code in this repo (website/ HTML, CSS, JS, service workers, PWA assets) or when asked to "review frontend", "revisa el html/css", "review JS", or "audita el frontend". Reviews for correctness, browser compatibility, accessibility, performance, security (XSS)…
Skill Claude CodeCodex
Use when reviewing, debugging, or giving feedback on Go code in this repo (exercises/part2, website/tools, or any .go file) or when asked for a "code review", "review this Go", "revisa este código Go", or "crítica de código". Reviews for correctness, idiomatic Go, error handling, resource cleanup, concurrency…
Skill Claude CodeCodex
Use when reviewing, debugging, or hardening Shell/Bash scripts in this repo (.github/workflows/.yml steps, website build scripts, or any .sh file) or when asked to "review bash", "revisa el script", "shellcheck", or "revisa el pipeline shell". Reviews for robustness, error handling, quoting, portability, injection…
