ui-ux-review-suite

User-triggered orchestrator that runs a comprehensive UI/UX review by coaching the user through four sibling skills as distinct lenses against one shared target, then synthesizing their findings into a single prioritized report. Composes user-journey-mapping (flow/funnel lens), ui-design-aesthetics (visual critique lens), interaction-design (state-coverage lens), and ux-review (usability-heuristics + WCAG lens). Resolves the review target once at suite start — the app/URL, the screens or flows under review, the viewports, and the user persona/goal — so every lens inherits the same scope and captured screenshots. Coaches rather than auto-runs — at each step it presents the next lens with its reframing prompt and an approval gate; the user invokes the sibling and confirms before moving on. Because the lenses overlap (ux-review already touches interaction and a11y), the suite scopes each lens to its distinct concern so the synthesis does not double-count. Produces one authored synthesis report — deduped findings grouped by severity and lens — not a navigation shell. Trigger on "run a full UX review," "comprehensive UI/UX review," "review this screen across all lenses," "do a complete design review," or when the user names two-or-more UI/UX lenses to coordinate. Not for running a single lens in isolation (invoke it directly), not for generating new UI (the generative siblings are reframed as critique here), and not for bypassing approval gates (this skill coaches, never autoruns).

ux-interaction-review

Combined UX and interaction design review: usability heuristics, state coverage, feedback patterns, timing, keyboard behavior, error recovery, and progressive disclosure. Use when reviewing how an interface works mechanically and whether interactions are well-designed for use.

NickCrew

wiring-audit

User-triggered audit that finds wiring drift between a project's UI surfaces and backend capabilities — orphan surfaces (UI calls endpoints/hooks/procedures that no longer exist), unwired capabilities (backend routes/exports that nothing surfaces), shape drift (both exist but contracts mismatch), method drift (URL matches, HTTP verb does not), validation drift (frontend vs backend rules diverged), permission drift (UI exposes what backend forbids or vice versa), stale labels (UI text references renamed backend concepts), and unsurfaced configuration (env vars or flags that gate behavior with no UI or CLI to control them). This skill should be used when the user asks to "audit our wiring," "find UI/backend drift," "find unwired capabilities," "find stale surfaces," "check for contract violations," "find unused endpoints," "find unused hooks," "what mismatches between UI and backend," or any similar request whose deliverable is a prioritized findings report rather than a descriptive snapshot. Generic across UI frameworks but optimized for React applications (hooks, fetch, react-query, SWR, tRPC, server actions, react-router, Next.js). Not for descriptive architectural snapshots (use architectural-analysis), security audits (use security-auditor), or performance audits (use the performance-optimization skills).

storyteller

Use this skill when writing fiction, narrative nonfiction, brand stories, or any content where emotional engagement and narrative arc matter more than pure information delivery. Trigger phrases: ''write a short story'', ''tell my brand''s origin story'', ''write a narrative about'', ''create a character''.

proofreader

Use this skill when reviewing written content for grammar, spelling, punctuation, style consistency, and tone—before publishing, submitting, or sending. Trigger phrases: ''proofread this'', ''check my writing'', ''review this for errors'', ''edit this email/report/essay''. Do NOT use when structural rewrites or content changes are needed—proofreading fixes surface errors, not substantive problems.

html-seo-review

Audit static HTML files for on-page SEO, content quality, easy-win performance signals, and crawlability. This skill should be used when the user asks to review, audit, or check the SEO of one or more static HTML files — e.g., "review the HTML for SEO issues", "audit this landing page", "check SEO on these pages before I publish".

justfile-author

Use this skill when authoring or refactoring a justfile (and matching Makefile wrapper) for one of Nick's projects. Triggers when the user asks to "create a justfile", "add a justfile to this project", "set up just for…", "wire up tmux services", "scaffold the task runner", or when working in a repo that lacks a justfile but obviously needs one. Produces a justfile using zsh syntax with the standard svc-* tmux service family, the canonical build/lint/dev/test recipes, a thin Makefile passthrough wrapper that auto-installs just, and per-service tx-start.sh helpers. Do NOT use for editing existing third-party justfiles or non-Nick projects unless the user explicitly opts in.

knowledge-stack

Use this skill whenever working inside any of Nick's repos (under ~/Developer/) or whenever a conversation touches Nick's durable cross-cutting work — Atlas Crew product strategy/brand/planning, the Unanet job, job search, interviews, tax amendment, foreclosure/tenant situation, strategic positioning. Maps Nick's three Basic Memory projects (products, work, main) and the per-repo dev trackers, and says which layer owns which kind of question. Consult before reasoning from stored memory summaries about repo architecture, product decisions, active priorities, or ongoing personal/career state — stored memory is lossy; the trackers and the Basic Memory projects are the real artifacts and should be consulted first.

mapping-suite

User-triggered orchestrator that walks the user through running multiple sibling mapping/audit/doc skills against a shared scope, then assembles their outputs into one navigable artifact. Coaches rather than auto-runs — at each step the orchestrator presents the next sibling skill, recommended scope inheritance, and approval gate; the user invokes the sibling and confirms before moving on. Resolves the prior arch-analysis lookup once at suite start so every sibling skill inherits the same scope. Records each run's output path in a suite manifest. Produces a combined navigation HTML that links to each sibling's standalone HTML for one-stop sharing. Ships two named recipes — "release-driver onboarding" (for tooling that drives releases) and "deployed-system onboarding" (for systems that get deployed) — and supports custom plans. Trigger on "run our mapping suite," "do a complete onboarding," "build the combined report," "I need to onboard to system X," "give me the full picture of this codebase," or when the user names two-or-more sibling analyses to coordinate. Not for running a single sibling skill in isolation (invoke it directly), and not for bypassing approval gates (this skill coaches, never autoruns).

market-researcher

Use this skill when sizing a market, analyzing competitors, designing customer surveys, segmenting audiences, or synthesizing research into market insights. Trigger phrases: ''size the market for'', ''analyze our competitors'', ''who is our target customer'', ''design a survey to understand'', ''TAM/SAM/SOM for''. Not for building financial models, writing pitch decks, or conducting UX usability research.

email-drafter

Use this skill when drafting professional or personal emails—cold outreach, follow-ups, internal memos, client communication, or any message that needs to be clear and effective. Trigger phrases: ''write an email to'', ''draft a follow-up'', ''help me email''. Do NOT use for mass marketing email campaigns (use copywriter skill) or legal/formal notices requiring specific language.

NickCrew

ai-tells-scan

Use when writing tasks produce prose artifacts (READMEs, docs, PR text, tutorials, guides, posts, release notes) and need a fast surface scan for AI tells. Auto-engages on prose writing tasks; checks banned punctuation, stock vocabulary, and mechanical patterns. For the structural judgment pass on rhythm and rhetorical reflexes, use ai-tells-review. Not a replacement for voice skills like nick-voice; this removes machine fingerprints, it does not add a target voice.

NickCrew
NickCrew

ai-tells-review

Use when public prose still sounds machine-written after ai-tells-scan. Complements ai-tells-scan's mechanical pass with structural judgment: rhythm, hedging, rhetorical reflexes, and performative emphasis. Trigger on 'review for AI tells,' 'does this read AI,' 'strip the AI smell,' or 'make this less AI.'
