react-pdf-kit Skill

Override the pdfjs-dist version and configure the PDF.js worker URL for @react-pdf-kit/viewer (>=2.0.0 <3.0.0) via the RPConfig workerUrl prop, with Vite, Next.js Turbopack, and webpack recipes. The default needs no setup.

react-pdf-kit Skill

Integrate @react-pdf-kit/viewer (>=2.0.0 <3.0.0) into a Next.js 15 App Router project using a 'use client' boundary and dynamic imports with ssr:false for RPConfig and the viewer.

react-pdf-kit Skill

Explains that @react-pdf-kit/viewer (>=2.0.0 <3.0.0) does not support Next.js 14, and the two supported paths forward — upgrade to Next.js 15 (Turbopack) or stay on the legacy @pdf-viewer/react package.

Owns the full lifecycle: clarify → contract (app.json) → screens with sample data → live preview in ~90s → backend actions → publish. Use when the user wants an app, dashboard, portal, form, approval queue, a board of things that move through stages, or any screens people will click.

roeibh Skill

rstudio Skill

Use when filling in the RStudio Desktop "What's New" page for a release from NEWS.md — writing, updating, or replacing the placeholder in src/node/desktop/src/assets/whats-new/<release-slug>/index.html. Trigger on phrases like "populate What's New", "add the What's New content", "update the What's New page", "What's New for <release name>", or any request to turn this release's NEWS.md entries into the window users see on first launch after an update.

ch4570 Bundle

Verify a completed UI change through a read-only review of scoped visual and behavioral evidence. Use for final UI/UX QA, completion checks, or release-readiness assessment after implementation; identify concrete task, accessibility, layout, state, and evidence gaps without changing product code or relying on beauty scores.

commet-labs Skill

Integrate and maintain Commet billing with the installed Node, Python, Go, Java, or PHP SDK and the Next.js, AI SDK, Better Auth, or CLI integrations. Use for subscriptions, usage, seats, checkout, customer portal, webhooks, feature access, payments, migrations, errors, or any repository that imports a Commet package.

conallob Skill

Render end-to-end previews of what an alert notification will actually look like (plain-text email, HTML email, Slack attachment JSON, raw webhook JSON) by replaying a Prometheus unit-test file's expected alerts through a live Alertmanager. Effectively a "print preview" for alerts. Use to review notification formatting/content before merging alert changes, or in CI against an ephemeral Alertmanager to produce a diffable preview artifact. Requires a reachable Alertmanager API and a promtool-style unit-test file as input. Can be made fully hermetic in CI by pointing the ephemeral Alertmanager at a skeleton config that keeps the team's real routing/grouping/inhibition rules but overrides receiver connection details, so no real notification ever leaves the runner.

contentstack Skill

HTTP stack for marketplace-sdk — Axios wrapper, retries, concurrency, params serialization, logging hook

contentstack Skill

App Router structure, React components, client vs server, and rendering patterns in kickstart-next.

contentstack Skill

TypeScript compiler options, ESLint setup, and Contentstack entry typing conventions for kickstart-next.

csprance Skill

Design and implement GECS reactive Observer nodes — component lifecycle handlers, query monitors (on_match/on_unmatch), relationship events, custom event emitters/subscribers, and sub_observer compositions. Trigger when modeling event-driven gameplay logic, cleanup/spawn reactions, UI-to-gameplay bridging, or any "fire when X happens" behavior that shouldn't be a per-frame System.

csprance Skill

Extend or modify the GECS editor debugger panel (`addons/gecs/debug/`) — the in-editor "GECS" tab that shows live entities, components, systems, relationships, and per-system metrics. Trigger when adding a new column, panel, status bar, or runtime control to the debugger; wiring a new `EngineDebugger` message from the running game to the editor; surfacing custom component or relationship data in the inspector tree; or fixing UI bugs in the existing debugger tab.

csprance Skill

Design and implement GECS Components — the pure-data Resources that entities compose. Trigger when adding a new gameplay concept (health, inventory, AI state, network sync, relationship payloads), splitting a bloated component, introducing tag/marker components, making a component observable via `property_changed`, or wiring `@export_group` sync tiers for `CN_NetSync`.

hacxy Skill

hameddk Skill

Comprehensive security audit for any software git repo — secrets (working tree + git history), dependencies, auth, OWASP Top 10, personal data handling, infra/CI-CD, STRIDE threat model. Every finding requires a concrete exploit scenario. Writes a committed self-contained HTML report to docs/SECURITY-AUDIT.html (latest only). Run monthly per product repo, or on demand before compliance-relevant releases. Heavy — expect 15–30 min.

hameddk Bundle

Use when asked to create, generate, or refresh a themed, self-contained HTML version of a project's docs — a rendered README/ROLES page, a hub/index landing page with a navigator grid, or an animated "teaser" landing page.

Works for any repo; scales from one page to a linked set across submodules.

Full architecture audit for any software git repo. Generates an architecture overview (stack, modules, routes, endpoints, config, secrets), audits layering and conventions, and flags components that belong in separate services. When a private company rubric is installed (private-docs/architecture-reference.md), matching repos are additionally audited against it. Writes a committed self-contained HTML report to docs/ARCHITECTURE-AUDIT.html (latest only). Run before merging any feature branch.

Use when the user asks to explain or document how a batch job, script, task, or pipeline works end-to-end, wants a "完整流程" / "flow walkthrough" / "walk me through this", or needs to understand execution order across an entry point.
