citypaul/.dotfiles

Design, audit, and evolve physical source and package structures that expose real architectural boundaries while keeping related behavior together.

Review test quality using Dave Farley's eight properties of good tests.

citypaul/.dotfiles

A skill your agent uses when modifying existing code that lacks tests and you need to document its actual current behavior before making changes -- the legacy code dilemma where you need tests to…

citypaul/.dotfiles

Research and compare established libraries, open-source tools and applications, managed services, and standard, framework, or platform primitives against an explicit bespoke baseline before…

citypaul/.dotfiles

Decide where a learning, gotcha, or decision should live so it is not lost, and capture it there while context is fresh.

citypaul/.dotfiles

A skill your agent uses when existing code has untestable dependencies that prevent writing tests -- direct construction of collaborators, static or global function calls, tight coupling to external…

citypaul/.dotfiles

Functional programming patterns with immutable data. An agent skill from citypaul/.dotfiles.

citypaul/.dotfiles

Set up and run mutation testing with Stryker, including full-project and focused diff runs against the current review base, then use surviving mutants to strengthen weak or missing tests.

citypaul/.dotfiles

Create an application-specific production parity skill by inspecting an app's docs, source, tests, CI, deployment, infrastructure, config, auth, and environment setup, then asking targeted harness…

React component testing patterns including components, hooks, context, and forms.

citypaul/.dotfiles

Refactoring assessment and behavior-preserving patterns for code with a passing baseline and proportionate preservation evidence.

citypaul/.dotfiles

Turn fuzzy intent into shared understanding and acceptance criteria — specification as a conversation, run one question at a time, before any story is split or planned.

citypaul/.dotfiles

Decide whether planned vertical implementation work should ship as independent pull requests or as a stack of small ordered pull requests, then plan, build, review, update, and merge the stack safely.

citypaul/.dotfiles

Turn broad requirements, large stories, epics, features, initiatives, or backlog items into small end-to-end child stories without turning them into technical component tasks.

citypaul/.dotfiles

Produce a mock-audit storyboard — a single HTML page embedding related UX surfaces side-by-side, with per-mock audit checklists, a flow diagram, and gap cards for missing mocks.

citypaul/.dotfiles

Twelve-Factor App patterns for software-as-a-service and long-running process applications.

citypaul/.dotfiles

TypeScript strict mode patterns including schema-first development, branded types, type vs interface guidance, and tsconfig strict flags.

citypaul/.dotfiles

Decide whether a system needs a backend-for-frontend, how many, and what each one may own: adoption signals and honest costs, one-experience-one-BFF granularity with frontend-team ownership, the…

citypaul/.dotfiles

Design and evaluate deep modules: cohesive responsibility behind a small, stable caller-facing contract, with information hiding, justified seams, explicit effects, dependency strategy, and…

citypaul/.dotfiles

WHEN diagnosing a reproducible or observable software failure outside a CI-pipeline-specific workflow; NOT for speculative cleanup, general code review, or speculative behavior changes presented as…

citypaul/.dotfiles

Compose installed agent skills into one orchestrated multi-agent run: an agent graph where each node is a sub-agent that loads exactly one skill, edges carry structured data, and stages fan work…

citypaul/.dotfiles

Audit an existing repository or multi-module subsystem for evidence-backed architecture improvements, rank bounded candidates, and present them in a visual HTML report with before-and-after diagrams…

citypaul/.dotfiles

Reduce total mechanism in a selected existing system or behavior path while conserving its agreed observable behavior and non-functional guarantees.

citypaul/.dotfiles

Design, implement, audit, test, troubleshoot, or migrate secure OAuth 2.0 and OpenID Connect (OIDC) systems using RFC 9700 / BCP 240.

Unix-composable CLI design patterns. An agent skill from citypaul/.dotfiles.

citypaul/.dotfiles

citypaul/.dotfiles

Event sourcing patterns for functional TypeScript — persist state as an append-only log of past events and rebuild it by folding them.

citypaul/.dotfiles

Adversarially review an existing written artifact — stories, plans, acceptance criteria, specs, or design mocks — to surface missing states, unhandled edge cases, unstated assumptions, unverifiable…

citypaul/.dotfiles

Behavior-driven UI testing patterns across Vitest Browser Mode, Playwright E2E evidence boundaries, and DOM Testing Library.

citypaul/.dotfiles

A skill your agent uses when the user or project explicitly adopts hexagonal (ports and adapters) architecture — a README, CLAUDE.md, or ADR that says so is the opt-in.

citypaul/.dotfiles

Planning work as vertical slices or an explicitly selected mechanism-reduction program in small, known-good increments, with independent pull requests or an optional stacked-PR topology across one…

citypaul/.dotfiles

Structured learning and tutoring for any topic. An agent skill from citypaul/.dotfiles.

citypaul/.dotfiles

Testing patterns for behavior-driven tests. An agent skill from citypaul/.dotfiles.

citypaul/.dotfiles

One ubiquitous language per bounded context, with a repository-declared glossary as the naming authority and explicit decisions for language changes.

citypaul/.dotfiles

WHEN deciding whether a PR, branch, diff, or current implementation satisfies an authoritative issue, specification, or decision contract; NOT for improving the written artifact, reconstructing…

citypaul/.dotfiles

Create or audit maintainable diagrams when relationships, sequence, state, hierarchy, or quantitative comparisons are materially clearer visually than in prose.

citypaul/.dotfiles

Re-explain the immediately previous LLM response when it did not land, using plain, precise UK English.

citypaul/.dotfiles

Writing developer-facing prose that can be skimmed first and trusted enough to finish — READMEs, guides, tutorials, reference docs, proposals, PR descriptions, release notes.
