This skill should be used when the user asks to "vibe an epic", "vibe #N", "drive epic #N to done", "solve the epic", "work through the epic's sub-issues", "finish the epic", "close out epic #N", "resume the epic", or wants an issue labelled `epic` taken to closure by agents, with triage of every child, fix PRs gated on CI, merges on green CI, scheduled status reports, and human rulings only where needed. Needs `gh` with push access and the `investigate` and `rebase-pr` skills; multi-agent Workflow mode needs the word `ultracode` in the invocation. Not for a single non-epic issue (use investigate). Also triggered by the /vibe command.

Regenerates the project's context index (index.yaml) from the YAML frontmatter across every context file, grouping entries by typology (findings/plans/goals/evidence/guides/follow-ups/handovers/merge-requests/tickets/decisions/notes/research), and validates that each file carries the required frontmatter fields. Also computes which active files are ready to work on, from optional typed `blocks`/`blocked-by` dependency links (scripts/context-ready.sh). Use when the index is stale, context files were added, renamed, or removed, a pre-commit gate blocks a commit because a context file is missing frontmatter, or someone asks what's ready/unblocked/blocked across the context backlog. Do not use it to create new context files (use create-context-file instead), to hand-edit the index, or as a substitute for fixing frontmatter at the source.

Write and maintain Behavior-Driven Development tests with Gherkin and Cucumber. Use when defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues. Keywords: bdd, gherkin, cucumber, given when then, feature files, step definitions, acceptance criteria, three amigos, example mapping.

Captures an important insight, decision, constraint, pattern, or discovery to persistent memory via the vault CLI — distinct from general note-taking in that entries are tagged, tiered, and retrievable across future sessions. Use when the user says "save this", "remember this", "note for later", "don't forget", or "keep this in mind", or when the conversation produces something worth preserving: architectural decisions, recurring bugs, hard-won constraints, naming conventions, or user preferences.

Use when adding, retiring, or auditing feature flags. Triggers on "add a flag", "ship behind a flag", "rollout plan", "kill switch", "stale flags", "flag debt", "LaunchDarkly", "GrowthBook", "Statsig", "Unleash", "Flipt", or any progressive-delivery question. Ships flag debt scanner, rollout planner, and kill-switch auditor (all stdlib Python), 4 references on flag taxonomy + provider trade-offs + rollout strategies + lifecycle, plus a /flag-cleanup slash command.

Configure and use EAS Update for over-the-air JavaScript and asset updates with expo-updates and EAS CLI. Use when setting up OTA updates, running eas update:configure or eas update, publishing to preview/staging/production channels, explaining branches/channels/runtime versions, testing updates, or debugging why an installed build still shows old code. Load for TestFlight, preview, or production updates that do not appear, including questions about cold launches or reopening the app. Not for update health metrics; use eas-update-insights for adoption, crashes, and rollout monitoring.

Run and control a user's app on a remote iOS/Android simulator hosted on EAS cloud. Read before running any `eas simulator:*` commands - it has the current syntax for this experimental API. Use whenever the user needs a simulator they can't run locally - 'run my app on a cloud simulator', 'use eas simulator to run/install/screenshot my app', 'I'm on Linux/Cursor and need an iOS device', 'no sim on this box / headless CI', 'let an agent click through my app and screenshot it', 'test my dev build on a remote sim with live reload', 'stream a sim to my browser' - even when they don't say 'EAS Simulator' or 'cloud'. On a host WITHOUT a local simulator (Linux, CI, cloud sandbox) it's the default; on macOS, do NOT auto-trigger for a plain 'run on the simulator' - use it only for a cloud/remote/shareable sim, an iOS version they lack, or an agent-driven session. NOT for local sims (expo run:ios, Xcode, Android Studio), EAS Build/Update, web preview, or physical devices.

Detects and removes overlays that block a webpage (cookie and GDPR consent banners, modals, newsletter popups, paywalls, login walls) with the web CLI, using Consent-O-Matic rules for known consent platforms plus DOM heuristics. Use before screenshotting, scraping, or automating a page that shows or may show such overlays, or when the user asks to dismiss cookie banners or popups.

Use this when the user asks to continue work in the SLICC browser agent or to install a skill into SLICC, for example "handoff to slicc", "move to the browser", "test in the browser", "install this skill in slicc", or "upskill slicc with this repo". Covers handing off the current task to the SLICC browser agent and installing a new skill into SLICC from a GitHub repo.

Use when validating an App Builder app before submitting to Adobe Exchange, or when the user mentions Adobe Commerce app compliance, extension review, marketplace submission, or Adobe Exchange listing. Checks security requirements, project structure, documentation completeness, and dependency health; reports MUST-have blockers and NICE-to-have recommendations and walks through each finding interactively.

Use this when making any AEM Edge Delivery Services (EDS, Franklin, Helix) code change — new blocks, block modifications, CSS styling, bug fixes, core functionality (scripts.js, styles, delayed.js), or any JavaScript/CSS work that needs validation. Covers the Content Driven Development process — identifying or creating real test content before writing code, designing an author-friendly content model, and validating against that content throughout development. Do not use for documentation-only changes or configuration changes that do not affect authoring.

Use this when you need to define acceptance criteria, write requirements, scope work, or create a definition of done for AEM Edge Delivery Services (EDS) tasks such as new blocks, variants, behavior modifications, CSS-only changes, or bug fixes. Covers analyzing development requirements, producing task breakdowns, identifying edge cases, and documenting the analysis.

Extract a DDD-style ubiquitous language glossary from the current conversation, flagging ambiguities and proposing canonical terms. Saves to UBIQUITOUS_LANGUAGE.md. Use when user wants to define domain terms, build a glossary, harden terminology, create a ubiquitous language, or mentions "domain model" or "DDD".

FDA regulatory consultant for medical device companies. Provides 510(k)/PMA/De Novo pathway guidance, QMSR (21 CFR 820, which incorporates ISO 13485:2016 by reference since 2026-02-02; formerly QSR) compliance, HIPAA assessments, and device cybersecurity. Use when user mentions FDA submission, 510(k), PMA, De Novo, QMSR, QSR, ISO 13485 for FDA, premarket, predicate device, substantial equivalence, HIPAA medical device, or FDA cybersecurity.

Multi-source recency research skill that takes the pulse of any topic across Reddit, Hacker News, the open web, and optionally X/Twitter within a configurable recent window (default 30 days). Forcing intake clarifies topic specificity, angle (trend/sentiment/problems/opportunities/comparison), time window, and platform scope before searching. Returns a synthesized briefing with citations, engagement metrics, and cross-platform pattern analysis. Use when the user requests multi-source recency intelligence on a topic (e.g., 'pulse on [topic]', 'what's happening with [topic]', 'what are people saying about [topic]', 'current conversation about [topic]', 'take the pulse of [topic]', 'trending: [topic]', 'find me info on [topic]'), and for competitor research, trend discovery, tool comparisons, and audience sentiment analysis.

Use when someone wants to grow reach through comments, replies, groups, or outreach on LinkedIn — a commenting roster, a connection request note, a DM or InMail, a networking plan, or a check on whether their outreach volume is safe. Triggers on "who should I engage with", "write a connection request", "cold DM", "LinkedIn outreach", "networking strategy", "how many invites can I send". Builds a weekly comment roster inside a real time budget, assembles one message at a time and refuses templates, and caps volume against LinkedIn's limits. Nothing is ever sent.

Use when coordinating product work across the 12 bundled product sub-skills (RICE, OKRs, UX research, design tokens, competitive teardown, analytics, experiments, discovery, roadmaps, spec-to-repo, landing pages, SaaS scaffolding) or the 4 standalone product-team plugins (user stories, Apple HIG, code-to-PRD, research summarizer). Triggers on 'help me prioritize', 'plan a product experiment', 'we ship features nobody uses', 'run the discovery loop', 'is our OST sound'. Forks context to route to one sub-skill via a deterministic signal router and returns a digest; can also drive a continuous-discovery loop (Torres cadence tracker + OST linter as machine gates) or a full goal→plan→execute→verify→close run through the repo-wide agent-harness. Distinct from project-management (how to deliver vs what to build), marketing/landing (from-scratch pages), and engineering/agent-harness (the generic loop engine this orchestrator plugs into).

Convert a rambling description of a desired outcome into one polished, autonomous /goal prompt ready to paste into a fresh session. Use when the user says "/fable-goal", "turn this into a goal prompt", "write me a fable prompt", "write the prompt that builds X", or rambles about something they want made and asks for the prompt that makes it happen. The output is a single copy-paste prompt, never the build itself. Do NOT use when the user wants the thing built right now in this session — only when they want the PROMPT that will make it happen in a fresh session.

Rails 7+ specialist that optimizes Active Record queries with includes/eager_load, implements Turbo Frames and Turbo Streams for partial page updates, configures Action Cable for WebSocket connections, sets up Sidekiq workers for background job processing, and writes comprehensive RSpec test suites. Use when building Rails 7+ web applications with Hotwire, real-time features, or background job processing. Invoke for Active Record optimization, Turbo Frames/Streams, Action Cable, Sidekiq, RSpec Rails.

Builds, optimizes, and debugs cross-platform mobile applications with React Native and Expo. Implements navigation hierarchies (tabs, stacks, drawers), configures native modules, optimizes FlatList rendering with memo and useCallback, and handles platform-specific code for iOS and Android. Use when building a React Native or Expo mobile app, setting up navigation, integrating native modules, improving scroll performance, handling SafeArea or keyboard input, or configuring Expo SDK projects.
