Maintain docs/RISKREGISTER.md, the living, append-only list of every deferred item, interim shortcut, and open architecture decision for this project. Use when a shortcut is taken, a decision is postponed, a follow-up is filed, or an existing entry is actually resolved. DO NOT use for accepted, finalized architecture…

Maintain docs/TECHDEBT.md, the living list of code-level cleanup that isn't a risk, a shortcut, or an open decision (that's the risk-register skill's job) and isn't a future feature (that's ROADMAP.md's job). Use when a lint/format/style violation slips past an existing gate, a small known cleanup is noticed while…
Skill Claude CodeCodex
Investigate a candidate library, dependency, or file format against a fixed question set and end with exactly one cited recommendation (adopt / keepcurrent / reject / needsmoreresearch) -- never "it depends." Validates the structured output against a JSON schema before writing a human-readable finding. Use when…

Integrate Biome into Nx monorepos with deterministic setup, caching, migration from ESLint and Prettier, and plugin-based inferred tasks; use when adding Biome, replacing ESLint/Prettier, tuning cache inputs, or scaling lint and format workflows across projects.
Skill Claude Code
Integrate Bun runtime into Nx monorepos with deterministic plugin setup, executor configuration, migration from Node.js toolchains, and cache-aware build/test workflows; use when adding the nx-bun plugin, converting projects, or standardizing Bun targets across Nx workspaces.
Skill Claude CodeCodex
Create Nx plugins with custom generators and executors for TypeScript monorepos. Covers plugin scaffolding, Tree API usage, schema-driven options, ExecutorContext API, template generation, project-graph-safe updates, cache-aware outputs, and testable workflows. Use when creating Nx plugins, building custom generators…

Configure and integrate Vite in Nx monorepos for applications and libraries. Covers vite.config.ts setup, framework plugins, TypeScript path resolution, asset copying, library mode builds, and Vitest integration. Use when: adding Vite to an Nx project, migrating from Webpack, configuring Vitest, fixing tsconfig path…
Skill Claude CodeCodex
Configure and optimize Nx monorepo workspaces with deterministic project-graph structure, boundary enforcement, cache-aware pipelines, and affected-command CI workflows; use when designing workspace architecture, tightening dependency rules, or reducing CI cost through Nx task orchestration.
Skill Claude CodeCodex
Find what a change could break somewhere else before it ships, beyond the diff, and prove the one fact it's safe because of by running real code instead of writing it up. Use for 'blast radius of X', 'what could this break', or reviewing a small diff you don't trust. DO NOT use for explaining how existing code works…

Capture a cross-project connection the moment it surfaces, such as a shared pattern, a person carrying context between projects, a story that lends another project credibility, a feedback loop. Use when one project feeds, reuses, reinforces another: 'connects to', 'feeds into', 'same pattern as'. Writes one YAML file…

Challenge, push back, play devil's advocate on AI output. Use when: challenge this, are you sure, push back, prove it, what if you're wrong, devil's advocate, stress test, poke holes, second opinion, sanity check, too confident, really?, question this decision. Subcommands: anchor (committed too fast), verify (facts…
Skill Claude CodeCodex
Given a user-provided set of coding standards (either as direct text input or as a link to a file/URL), systematically review the codebase to identify violations, report findings, and optionally remediate them. The model MUST ask the user for the standards — never guess or assume them.

Stress-test an unwritten idea or decision by spawning independent subagents in genuinely OPPOSING roles (advocate, skeptic, migration/risk) rather than complementary review lenses — grounded in real repo investigation, not assumption, and concluding in a synthesized verdict rather than a list of opinions. Use for…
Skill Claude CodeCodex
Apply Clean Architecture principles to define layer boundaries, identify dependency violations, and structure domain vs infrastructure code. Use when designing service boundaries, separating business logic from infrastructure, evaluating hexagonal/onion/ports-and-adapters architecture, structuring module layout, or…
Skill Claude Code
TypeScript design patterns that use the type system to enforce correctness at compile time — the builder pattern with required-field tracking, type-safe state machines and event emitters, dependency injection, plugin systems, recursive/deep-readonly utility types, type-safe module encapsulation, advanced generic…
Skill Claude CodeCodex
Apply SOLID principles (SRP, OCP, LSP, ISP, DIP) for tactical class design, method extraction, and interface definition. Use when reviewing class design, refactoring code for maintainability, or designing interfaces and abstractions.
Skill Claude CodeCodex
Design code for testability using boundary isolation, dependency injection, and testable architecture patterns. Use when designing test strategies, writing unit tests, improving test coverage, refactoring untestable or hard-to-test code, working with mocking or test doubles, or applying TDD practices.
Skill Claude Code
Master higher-order functions, map/filter/reduce patterns for expressive data transformations.
Skill Claude Code
Apply immutability principles across languages for safer, more predictable code.
Skill Claude Code
Write pure functions and avoid side effects for predictable, testable code.
Skill Claude Code
Sense-making before action. Classify problem using Cynefin triangulation (3 tests + decomposition) to route to the right skill chain. Use when: frame, what approach, how should I start, which skill, where to begin, unsure what to do. NOT for known tasks — just do them.
Skill Claude CodeCodex
Use for "how does X work", code walkthroughs before changing something, and placement / ownership / layering questions ("where should this live", "which package owns this", "is this the right layer"). Explains subsystem architecture, runtime flow, onboarding mental models. Can critique architecture. DO NOT use for…

Safe-to-fail experiment for Complex domain problems where cause-effect is only visible in retrospect. Two-phase: foreground qualify → background probe → sense result. Use when: probe, safe-to-fail, test hypothesis, experiment with hypothesis, Complex domain with hypothesis. NOT for brainstorming (use brainstorm) or…
Skill Claude Code
Use when designing solutions, adding features, or refactoring by applying KISS, YAGNI, and Principle of Least Astonishment to write simple, predictable code.
