ak-ship Skill

Find and fix the actual bottleneck — not the one you assume. Profiles before optimizing, measures before and after, refuses to "rewrite for perf" without numbers. Covers React/Vue rendering, bundle size, database query plans, N+1 patterns, memory leaks, and Node.js event-loop lag. Use when the user says "make this faster", "why is this slow", "optimize this", "the page is laggy", "the query is slow", or "this endpoint times out".

mryll Bundle

Create or review C4 model architecture documentation (official c4model.com notation) as diagrams-as-code in Markdown — C4-PlantUML where the target renders it (GitLab.com does; verify Self-Managed instances), Mermaid flowchart/sequence conventions otherwise. Use whenever the user wants to visualize or document the architecture of a system or codebase — even if they never say "C4" — for requests like "diagram this service", "document the architecture", "how do the pieces of this repo fit together", "draw the system/containers/components", or when reviewing existing C4/Mermaid architecture diagrams for correctness. Covers system context, system landscape, container, component, dynamic, and deployment views. Do not use for generic flowcharts, ER diagrams, standalone Kubernetes topology, API contract documentation (OpenAPI/AsyncAPI), or architecture prose without diagrams.

objectstack-ai Bundle

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.
