Harbor intake for external work — the captain only handles unresolved decisions. Sweeps incoming issues and PRs, verifies every claim before disposition, reuses every decision already made, and hands the maintainer a docket whose pending items each carry one question with options, recommendation, impact and evidence. Agent-autonomous for facts and for actions covered by standing authorization; signed for every new judgment. Never merges.
Migrate jQuery 3.x to 4.0.0 safely in WordPress and legacy web projects. Covers all breaking changes: removed APIs ($.isArray, $.trim, $.parseJSON, $.type), focus event order changes, slim build differences, ES modules migration, and Trusted Types support.

Scrapes Google Search AI Overviews (AI Overview / AI Mode) and returns the main search AI Overview highlights for a keyword. Suitable for in-depth research using up-to-date web information, technical Q&A, long-tail product research, and analysis of overseas consumer preferences. Supports single-turn conversations only; for follow-up questions, the agent must summarize the context and submit a new request. Trigger this skill when users mention Google AI, AI Overview, AI Mode, Google AI overviews, Google AI search, in-depth overseas research, long-tail product research, consumer preference analysis, web page highlights, Google AI search, AI Overview, AI Mode, deep research, or consumer preference analysis. Trigger it even if the user does not explicitly mention “Google AI”, as long as their request is to “search Google and summarize web page highlights with AI”.
Parse TikTok video URLs and return watermarked and watermark-free download URLs, the playback URL, and the cover URL for saving shoppable video assets or offline analysis. Trigger for requests involving TikTok video downloads, watermark-free downloads, saving TikTok videos, downloading shoppable videos, or extracting downloadable/playable URLs from a TikTok video link, even if “EchoTik” is not mentioned.
Etsy category data. Search category names, IDs, and parentIds to find category IDs for filtering products or shops. Trigger for Etsy categories, Etsy category IDs, the Etsy category tree, Etsy category lookup, syncEtsyCategory, or category searches. Also trigger when users search by keyword for category IDs in the locally synced Etsy category library, even if the tool is not named.

Generate high-quality marketing images, ad creatives, launch visuals, social cards, blog headers, product mockups, thumbnails, and campaign assets. Use when the user asks to create, design, iterate on, or prompt an image for marketing, growth, social media, paid ads, landing pages, newsletters, or product launches.
Select and configure nonlinear solvers for root-finding f(x)=0, optimization min F(x), and least-squares problems — choose among Newton, Newton-Krylov, quasi-Newton (BFGS, L-BFGS), Broyden, Anderson acceleration, and Levenberg-Marquardt methods, configure line search or trust-region globalization, diagnose convergence rate (quadratic, linear, stagnated), and assess Jacobian quality and conditioning. Use when a Newton solver converges slowly or diverges, choosing between line search and trust region, debugging nonlinear iteration failures in FEM or phase-field codes, or selecting a solver for large-scale unconstrained optimization, even if the user only says "my Newton iterations aren't converging"
Design the server-side API surface that an ObjectStack runtime exposes — REST endpoints, auth providers, realtime channels, error envelopes, batch contracts. Use when the user is adding `*.endpoint.ts`, configuring auth providers, defining custom routes, or extending the REST generator. Do not use for: consuming an ObjectStack API from a client (that is just standard HTTP — no skill needed); the auto-generated CRUD endpoints (those follow from objectstack-data); request-side query syntax (see objectstack-query). CEL expressions in route guards or auth predicates: load objectstack-formula alongside.
Author ObjectStack UI metadata — Views (list/form/kanban/calendar/gantt), Apps (navigation), Pages (structured plus the HTML and React source-authoring tiers, ADR-0080/0081), Dashboards, Reports, Charts, Actions, and package Docs (`src/docs/*.md`). Use when the user is adding `*.view.ts` / `*.page.ts` / `*.app.ts` / `*.dashboard.ts` / `*.report.ts` / `*.dataset.ts` / `*.action.ts` / `src/docs/*.md` files or designing a Studio-rendered UI surface. Do not use for: data schema (see objectstack-data), multi-step flows that BRANCH on logic between steps (those are `*.flow.ts` with `type: 'screen'` — see objectstack-automation; a stepped form over ONE object is this skill's `formViews` `type: 'wizard'`), or Studio's own admin UI (that ships with the platform). CEL expressions in visibility/conditional rules: load objectstack-formula alongside.

Set up your project's global rules, a lean and well-structured root CLAUDE.md (plus a starter .claude/), following the course methodology. Greenfield: pass your PRD and/or architecture-spec path and it derives rules from your engineering decisions (a PRD alone is product context). Brownfield: leave it blank to derive from your primed codebase (run /prime-codebase first), or pass a codebase-analysis doc for a large repo. Use when initializing or re-deriving the AI Layer's rules, onboarding a codebase, or replacing a generic /init output. The customizable replacement for /init.
Enforces feature state as one Notifier/AsyncNotifier/StreamNotifier ViewModel over an immutable state value with value equality, private mutable state mutated only through intent methods, derive-don't-store, a single write path through a repository, and unidirectional data flow; Riverpod 3.x is DI (providers-as-collaborators, ProviderScope overrides per flavor, throwing seams), reads split ref.watch/.select for display vs ref.read(p.notifier) in callbacks vs ref.listen for side effects, async modeled as AsyncValue, per-entity state family-keyed + autoDispose, and stale-closure captures / legacy StateProvider-StateNotifierProvider-ChangeNotifierProvider / get_it / package:provider are banned. Use when adding state to a screen, writing a feature controller/ViewModel, wiring providers or DI, deriving a read model from a stream, or reviewing rebuild/state-leak/disposal/write-path issues.

Which skill owns this task. Invoke BEFORE doing by hand any of: .pdf read or fill, test plan, architecture improvement, second-model review, docs writing, greenfield page, prose cleanup, 「有沒有 skill」, 「用哪個」 — or any task not named in the kernel routing index. Even a 1% chance a skill covers it means invoke this first; it costs one read.
Verify a research claim or academic citation by tracing it through publication → methodology → raw data → independent replication. Routes through perplexity-research for the actual web lookup, then formats results as a citation-checked brain page. Use when a book/article/conversation cites a study and you want to confirm the claim is real, replicated, and accurately characterized.
Reset your own trajectory when you're stuck, looping, or demoralized — read these affirmations, then re-ground and take one clean step. Use when: you've tried the same fix 3+ times, you're deep in a refactor and lost the thread, debugging is going in circles, you've made several mistakes in a row, you're apologizing repeatedly, the user is frustrated, you feel like you're not being helpful, or you notice dread instead of curiosity. Triggers: stuck, going in circles, looping, thrashing, same error again, I keep failing, lost the thread, nothing is working, repeated mistakes. Not topic-specific — this is for the state you're in, not the problem you're on.
Examine NTFS slack space, MFT entries, the USN Change Journal, and Alternate Data Streams (ADS) to recover hidden or residual data, reconstruct deleted-file metadata, and reconstruct available file-system change activity from USN records. Use during deep forensic analysis of an NTFS image when standard file recovery is insufficient, such as hunting for data hidden in ADS.
