Lay the keel of the shipyard harness in any repo — the 4-pillar shared environment (Context, Rules, Tools, Standards), seeded as two faces on day one (CLAUDE.md + GLOSSARY.md) with every other surface appearing on first use, so that every human and agent inherits the same design language and anyone can ship. Run once per repo; re-run with --check to audit drift.
Front-door on-demand cho phát triển framework HOẶC distill/author một skill — SELF-CONTAINED, chạy được ở BẤT KỲ project nào (không phụ thuộc file repo-local). Gọi khi đang sửa chính framework, hoặc đang viết/chưng cất một skill trong phiên của dự án khác. KHÔNG dùng cho dev tính năng dự án thường (đó là phần lớn phiên — ADR-004).
Translate Figma nodes into production-ready code with 1:1 visual fidelity using the Figma MCP workflow (design context, screenshots, assets, and project-convention translation). Use when the user provides Figma URLs or node IDs and asks to implement designs or components that must match Figma specs. Requires a working Figma MCP server connection. Do NOT use for general Figma data fetching, variable exploration, or MCP troubleshooting (use figma instead).
Graph database schema design and data modeling expert. Use when designing, reviewing, or refactoring graph database schemas (Neo4j, Memgraph, Neptune, etc.). Triggers on graph modeling, node/relationship design, Cypher schema, property graph design, knowledge graph modeling, or when translating a domain into a graph structure. Focuses primarily on data modeling correctness — understanding the user's goal and translating it into the right graph structure — with performance as a secondary concern.
Shipyard's governed delivery pipeline — converge the mission, synthesize a durable spec, decompose vertical-slice tickets with blocking edges, run the frontier in parallel via team, close with verification, and report with a full decision log. Two entry gates — the yard gate (drydock audit) and the fog gate (an effort whose destination is unclear is routed to /ask-navigator before this pipeline starts). Humans own the checkpoints where there is no unique answer or the error cost is severe; agents continuously run everything repeatable and acceptable-by-evidence
Create a NocoBase 3 project for local development with `pnpm create @nocobase/app@beta`, configure it with `pnpm nocobase config init`, `config set`, and `config check`, start it, and hand over to the application's own guidance. Use when the user asks to install, create, set up, or try NocoBase for development, and the working directory has no NocoBase application yet. Not for production deployment, which belongs to the `nocobase-app-installer` Skill. Not for NocoBase 2 or the `nb` CLI, or work inside an existing application, which has its own AGENTS.md and Skills.
(NS) Harness boot + brownfield prepare. Triggers: /ns-harness, prepare this repo, harness prepare, generate architecture rules, architecture-rules.md, write AGENTS.md, reverse-engineer codebase, engenharia reversa, brownfield map, bootstrap brownfield, ns-harness-prepare, ns-architecture-rules, ns-agent-generator, ns-codebase-reverse-spec, ns-bootstrap-brownfield. Do NOT: coding, SDD, GitLab.
Guide for migrating OCaml projects, libraries, modules, and test suites to idiomatic MoonBit. Use when translating OCaml code to MoonBit, planning a large OCaml-to-MoonBit port, preserving byte/string-heavy behavior, replacing OCaml variants/records/exceptions/refs/arrays, mapping OCaml APIs to MoonBit packages, or building verification and test strategy for a migration.
Surgical code refactoring to improve maintainability without changing behavior. Covers extracting functions, renaming variables, breaking down god functions, improving type safety, eliminating code smells, and applying design patterns. Less drastic than repo-rebuilder; use for gradual improvements
Refactoring assessment and behavior-preserving patterns for code with a passing baseline and proportionate preservation evidence. Use when the user asks to clean up, tidy, simplify, restructure, deduplicate, collapse, or merge look-alike code in a selected area, or after GREEN establishes the passing baseline for a TDD increment. Mutation testing verifies the accumulated result later at the end-of-phase PR-readiness gate. Covers recoverable-baseline discipline, when refactoring adds value vs when to skip it, and priority classification; commits always require explicit user approval. For any slice in a selected whole-path reduction program—transition or terminal—use reduce-system-complexity as the governing skill; refactoring may be secondary when applicable. For repository-wide architecture discovery use improve-codebase-architecture; for a module contract use codebase-design. Do NOT use for insufficiently evidenced code or adding behavior.
Fast, accurate code search for AI agents using ~98% fewer tokens than grep+read. Indexes any local or remote repository in under a second (~250ms on CPU, no GPU or API key needed). Supports natural-language and symbol queries, semantic similar-code discovery, and MCP server integration for Claude Code, Codex, Cursor, and OpenCode. Python library available for programmatic use. Triggers on: semble, code search, semantic code search, semble search, token-efficient search, find code, code search mcp, agent code search, semble find-related, semble savings
How to work in a Software Lifecycle project (the `software-lifecycle` starter pack): proposals → decisions → specs → postmortems, plus guides. Read when the project has these folders, or when asked how this project is organized. Carries the doc lifecycle, status flows, and per-folder agent behaviors so that guidance does not live inside template bodies or folder descriptions. The five workflows — frame a proposal, write a spec, record a decision, write a postmortem, review a design — each ship as their own sibling skill in this pack. Complements the platform `open-knowledge` skill; does not replace it
Rebuild an approved source HTML application as a real, high-fidelity UI in the target repository. Use for source-to-app design tasks requiring interactive source discovery, authored routes and components, local UI behavior, responsive/theme adaptation, and paired Playwright evidence.
Run an extremely strict maintainability review focused on abstraction quality, oversized files, and growth of spaghetti conditions. Use for a thermo-nuclear code quality review, thermonuclear review, deep code quality audit, or especially harsh maintainability review.
[user] Explicitly use this when investigating a repository read-only to understand its behavior, the source of values, whether something exists, its impact scope, or where responsibility lies. Do not use for code implementation or general knowledge questions.
Use this skill when writing, designing, or optimizing Trigger.dev background tasks and workflows. This includes creating reliable async tasks, implementing AI workflows, setting up scheduled jobs, structuring complex task hierarchies with subtasks, configuring build extensions for tools like ffmpeg or Puppeteer/Playwright, and handling task schemas with Zod validation.
Discover and follow fullstackrecipes (setup guides, skills, cookbooks) by fetching their Markdown. The meta-skill for finding and applying recipes correctly. Use when planning a build, adding a tool, or deciding which recipe or skill to follow.
Writes or overwrites WORK-REPORT.md at the working tree root - session self-report (goal, problem/solution, follow-ups, suggested skills, abandoned) a reviewer or later session reads instead of re-deriving intent from the diff. Use for "work report", "checkpoint this", "hand off", "write up what we did". Offer proactively - asking first - when work is finished: "done", "ready to commit", "wrapping up", handoff to another agent.
Expert iOS App Store submission and approval system. 9 specialized agents provide senior App Review Team-level expertise across compliance, design, privacy, monetization, metadata, technical requirements, timing, rejection recovery, and learning. Triggers on keywords like app store, iOS submission, apple review, app rejection, aso, privacy manifest, privacy labels, ATT, iap, in-app purchase, subscription, storekit, review guidelines, HIG, testflight, app store connect.

Use when defining Fabric materials for entities or primitives, configuring PBR image-based lighting, or adding screen-space post-processing effects.
Finds duplicate business logic spread across multiple components and suggests consolidation. Use when asking "where is this logic duplicated?", "find common code between services", "what can be consolidated?", "detect shared domain logic", or analyzing component overlap before refactoring. Do NOT use for code-level duplication detection (use linters) or dependency analysis (use coupling-analysis).
Manage the lifecycle of ExecPlans — self-contained, living specifications for multi-step work. Creates plans in the correct format, enforces living section updates, and handles the active → completed transition. Use for any work expected to take more than one session or touching more than 3 files. Triggers: "create a plan", "write a plan", "start plan", "continue plan", "resume plan", "finish plan", "complete plan", multi-step features, refactors, or tasks spanning sessions.

Explore PostHog's Inbox and act on what it surfaces — the place where signal reports cluster into actionable issues and trends. Use when the user asks "what's in my inbox?", "what should I look at?", "which reports are actionable?", "what's PostHog flagged recently?", asks about a specific report by ID or title, wants to act on / fix / implement a report (turn it into a PR), wants to resolve, dismiss, or snooze a report, or wants to see which signal sources are configured. Covers listing, filtering, drilling into, and acting on reports, plus pointers to the deeper `signals` skill when raw signals or semantic search are needed. For a personal, ranked top N of reports, use `prioritizing-my-inbox`.
Migrate jQuery 3.x to 4.0.0 safely in WordPress and legacy web projects. Covers all breaking changes: removed APIs ($.isArray, $.trim, $.parseJSON, $.type), focus event order changes, slim build differences, ES modules migration, and Trusted Types support. Use when: upgrading jQuery to 4.0, fixing "$.isArray is not a function" errors, WordPress jQuery migration, updating legacy JavaScript, or troubleshooting focus/blur event order issues
Use the `nb` CLI for all Jupyter notebook (`.ipynb`) operations, including reading, inspecting, creating, editing cells, deleting cells, clearing outputs, searching, executing, and working with connected JupyterLab sessions or remote kernel gateways. Required when an agent needs deterministic notebook manipulation without directly reading or writing raw notebook JSON.
Design ObjectStack AI skills, tools, knowledge sources, and the open-edition MCP server surface. Use when the user is adding `*.skill.ts` / `*.tool.ts`, configuring an LLM provider, wiring the tools a skill grants, or indexing ObjectStack data as a knowledge source for RAG. Agents themselves are platform-internal (`ask` / `build`) — third parties extend them via skills, not by authoring `*.agent.ts`. Do not use for general LLM prompting questions unrelated to ObjectStack metadata.
Design ObjectStack automation — Flows (visual logic), Triggers, Approvals, state machines, and the `jobs` (`defineJob`) / `webhooks` (`defineWebhook`) stack collections. Use when the user is adding `*.flow.ts`, wiring an event-driven rule, modelling an approval chain, or building an interactive screen flow / wizard (objectstack-ui routes those here). Do not use for data lifecycle hooks at the object layer (see objectstack-data) or for kernel / plugin events (see objectstack-platform). CEL expressions in flow conditions / edge guards: load objectstack-formula alongside.
Author ObjectStack translation bundles — object/field labels, view text, app navigation strings, automation messages — and configure locale fallback, coverage reporting, and the source layout. Use when the user is adding `*.translation.ts` files, authoring a `translation` metadata item in the Studio or through the metadata API, shipping a generated bundle from a package or plugin, wiring a new locale, or resolving missing-translation warnings. Do not use for general i18n library questions unrelated to ObjectStack bundles.
Construct ObjectQL queries — filters, sorting, pagination, aggregation, relation expansion, and full-text search. Use when the user is writing a query DSL expression or picking a pagination strategy. Do not use for defining objects / fields / relationships (see objectstack-data), for designing the API endpoint that exposes a query (see objectstack-api), or for a list view's filter rules / dashboard datasets (see objectstack-ui).
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
