UncategorizedView skill →

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).

UncategorizedView skill →

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).

agent-loops

Complete operational workflow for implementer agents (Codex, Gemini, etc.) making code changes and writing tests. Drives all work through atomic commits — each loop operates on the smallest complete, reviewable change. Defines the Code Change Loop, Test Writing Loop, Lint Gate, and Issue Filing process with circuit breakers, severity levels, and escalation rules. Requires `cortex git commit` for all commits. Includes bundled provider-aware review scripts that keep same-model shell-outs as the last resort, plus a fresh-context Codex fallback for code review and test audit. Use this skill when starting any implementation task.

UncategorizedView skill →

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.'

UncategorizedView skill →

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.

This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

UncategorizedView skill →

Use when filing, updating, sequencing, or querying tasks in any atlas-crew repo (Facet + the Atlas Crew Security repos: Apparatus, Chimera, Crucible, Synapse, Bridge). These repos track work in GitHub Issues on Projects v2 boards, NOT backlog.md. Covers the two boards, the Type/Area/Status field model, cross-repo Initiative grouping, gh seq execution ordering, and the non-obvious gh/GraphQL mechanics for setting issue types and project fields. Trigger on: file an issue, create a task, set priority/type/area/status, add to board, what should I work on next, execution order, sequencing, blocked-by, milestone, where does this task go.
