Trigger phrases: ''critique this design'', ''give feedback on my UI'', ''review this wireframe'', ''what''s wrong with this design''. Do NOT use for writing code, implementing designs, or marketing material critique.
design-journey-review
Combined visual design and user journey review: color systems, typography, spacing, information density, visual hierarchy, workflow stages, emotional curve, friction points, and daily-use optimization.

doc-claim-validator
Validate that claims in documentation match codebase reality. Extracts verifiable assertions (file paths, commands, function references, behavioral claims, dependencies) from markdown docs and checks them against the actual project. Use after code changes, before releases, or when docs feel untrustworthy.
doc-completeness-audit
Audit documentation completeness by mapping what a doc set should cover against what it actually covers. Produces a prioritized gap report by topic, not just by file. This skill should be used after shipping features, before releases, or when users report missing documentation.
doc-health-audit

Runs each phase in dependency order with phase gating. This skill should be used for pre-release audits, periodic health checks, or comprehensive documentation assessments.
doc-maintenance
Systematic documentation audit and maintenance. This skill should be used when documentation may be stale, missing, or misorganized — after feature work, refactors, dependency upgrades, or as a periodic health check. It prescribes folder structure for docs/ and manual/, dispatches haiku subagents for codebase/doc scanning, and routes doc creation to specialized agents (reference-builder, technical-writer, learning-guide) with docs-architect as quality gate.
doc-quality-review
Assess documentation quality across readability, consistency, audience fit, and prose clarity. Produces a scored review with actionable findings. This skill should be used before releases, during doc reviews, or when documentation feels unclear or inconsistent.

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.

legacy-modernization
Modernize legacy systems using proven migration patterns like strangler fig, feature flags, and incremental refactoring. Use when planning system migrations, modernizing monoliths, or managing technical debt.
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.

multi-llm-consult
