When the user wants to optimize electronics manufacturing supply chains, manage semiconductor sourcing, handle PCB assembly, or navigate component allocation. Also use when the user mentions "electronics manufacturing," "semiconductor supply chain," "PCB assembly," "EMS/ODM," "component allocation," "lead time management," "electronics sourcing," "PCBA," "contract manufacturing," or "electronics lifecycle management." For general manufacturing, see production-scheduling. For quality, see quality-management.
Prepare submissions to Elsevier journals (including The Lancet family style notes, Cell-independent Elsevier titles, and thousands of society journals) using the elsarticle LaTeX class, the CAS single/double-column templates or Word, covering highlights, graphical abstracts, keywords, CRediT author statements, declarations of interest, generative-AI disclosure, data availability, reference styles per journal, Editorial Manager submission and "Your Paper Your Way" format-free first submission. Use when targeting an Elsevier journal or fixing elsarticle/CAS template issues.
Build or update a canonical EPISTEMIC-MAP.md sorting a project's knowledge into four states: validated Facts, open Questions, undocumented Assumptions, and inferred Risks. Purpose-built for prototype-to-production handoff, where a signed contract means a new engineering team must take over before the original builder's tacit knowledge walks out the door. Spawns subagents across docs and the codebase to find what's proven, what's asked, what's silently assumed, and what nobody has noticed, then runs a dedicated synthesis pass for systemic risks no single source states. Use whenever a user mentions \"epistemic map\", \"knowledge map\", \"EPISTEMIC-MAP.md\", \"known unknowns\", \"unknown unknowns\", \"what do we actually know vs assume\", \"map our assumptions\", \"handoff risk map\", \"prototype handoff\", or \"onboarding a team onto a prototype\". Always prefer this skill over ad-hoc knowledge-gap documentation.
Designs neural network architectures that respect validated symmetry groups, recommending architecture families (G-CNN, steerable CNN, e3nn), layer patterns, and implementation libraries. Use when you have validated symmetry groups and need equivariant architecture design, or when user mentions equivariant layers, G-CNN, e3nn, steerable networks, or building symmetry into a model.
Turn original SRT and design into editable B-roll through an independent Director, focused chapter creators, and visual review. Use for SRT-to-video production or revisions; preserve existing legacy projects and explicit Remotion choices.
Safely diagnose and fix ESLint errors, warnings, and configuration compatibility issues. Use when the user asks to run lint, explain ESLint errors, perform scoped auto-fixes, or migrate ESLint configuration; prefer the project's locked package manager and versions, pre-check before modifying, and do not automatically download the latest version or bulk-rewrite unrelated source code.
Use when you have an approved implementation plan document and need to execute it step by step. Triggers on /execute command, when transitioning from planning with an approved plan, or when resuming execution of a partially completed plan. Provides batch-based execution with TDD, checkpoint reviews, and verification gates.
SQL injection detection and exploitation using sqlmap, manual techniques, and custom payloads. Use this skill when the user needs to test for SQL injection vulnerabilities, extract database information, or exploit SQLi in parameters, headers, or cookies.
Lints, tests, simulates, and formats Fastly VCL code using the falco tool. Also serves as the authoritative VCL reference via the falco Go source, which implements Fastly's full VCL dialect. Use when validating VCL syntax, running VCL linting, testing VCL locally, simulating VCL request handling, formatting VCL files, writing VCL unit tests with assertions, debugging VCL logic errors, looking up VCL function signatures or variable scopes, understanding VCL subroutine behavior, or running `falco lint`/`falco simulate`/`falco test`/`falco fmt`. Also applies when working with VCL syntax errors, type mismatches in VCL, choosing which VCL subroutine to use, or setting up a local VCL development and testing environment.
Design feedback and status communication that works across senses — visual, auditory, and haptic. Use when designing loading states, success messages, progress indicators, notifications, alerts, or any system response to user action. Triggers on: feedback, status, notification, alert, loading, progress, success message, confirmation, toast, snackbar, screen reader announcement, aria-live, colour alone.
Diagnose and fix Flutter text display issues including text overflow, orphaned words, line breaking, truncation, multi-style spans, and text scaling. Use when text clips, leaves dangling single words, overflows containers, or requires rich inline spans; route typography tokens and visual hierarchy to flutter-ui-design and screen-level layout constraints to flutter-responsive-layout.
Use when you need to derive a "page inventory → feature points → business processes → business rules" chain from frontend code with evidence, especially when the project has more than one routing entry point, complex dynamic routes/permissions/backend menus, and the team tends to speculate or miss evidence links.
Use this skill for frontend UI work that must preserve or extend a product's real design system: new screens/components, high-fidelity rebuilds, restyles, non-trivial forms, role-gated UI, substantial behavior changes, or UI implementation that needs layout, experience, style-guide, clean implementation planning, and final code generation. This is the single frontend skill to install; it is self-contained and routes between lightweight UI edits and the full frontend workflow using bundled references.
Invoke when the user works with Unity or asks about C#, MonoBehaviour, DOTS/ECS, Shader Graph, Addressables, UI Toolkit, URP/HDRP, or ScriptableObjects. Triggers on: "Unity", "MonoBehaviour", "DOTS", "ECS", "Shader Graph", "Addressables", "UI Toolkit", "URP", "HDRP", "ScriptableObject", ".unity", ".cs". Do NOT invoke for engine-agnostic architecture (use game-technical-director) or Godot/Unreal questions. Part of the AlterLab GameForge collection.
Detect host inventory and effective CPU, memory, disk, scheduler, container, and accelerator limits when a user asks for resource-aware planning or before a clearly resource-sensitive local workload. Produces a redacted JSON snapshot and conservative planning helpers without stress tests or assuming visible host hardware is usable.
Use when the user needs help with conventional commits, semantic versioning, changelog generation, or commit message quality improvement. Triggers: user says "commit", "version bump", "changelog", "commit message", staging changes for commit, preparing a release.
Use when a Git merge or rebase produces code conflicts, especially when AI-automated conflict resolution is error-prone (picking the wrong side, losing a refactor, reverting to an older version) and semantic analysis plus logic verification is needed. Also applies when a multi-round rebase stops repeatedly and conflict files need to be aggregated across rounds. Triggers — 「解冲突」「处理冲突」「git-conflict-resolve」「解决 merge 冲突」「解决 rebase 冲突」「冲突解决」 / conflict resolve, resolve merge conflict, resolve rebase conflict.

Query Huawei Cloud ECS elastic cloud server information. For queries only; it does not perform write operations such as creating, deleting, or changing instance specifications. Use when the user wants to view Huawei Cloud ECS instance lists, details, or status. Supports AK/SK and Token authentication, table and JSON output, and multi-region queries. Enhanced output with --detail/--full adds operational fields such as system/data disk size and type, security groups, VPC/subnet, image name, key pair, tags, EIP bandwidth, and billing mode. Trigger when the user asks to "query cloud server list", "view ECS instance details", check "ECS status", "list ECS", or "view server status", or requests read-only information about ECS properties other than updates/modifications/creation/deletion (such as flavor, availability zones, or images). Use another skill for write requests (create, delete, change specifications, start/stop).
Find roll options for existing short positions OR find best covered call/put to open against long stock. Use when user asks about rolling shorts, finding roll candidates, writing covered calls, or managing option positions. Requires TWS or IB Gateway running locally.
Build a sized Instagram hashtag set for a post using the 2026 reality that 3 to 5 well-chosen tags beat 30 random ones. Sizes each tag as niche (under 50k posts), mid (50k to 500k), or broad (500k+), then assembles a 2-3 niche, 1-2 mid, 0-1 broad mix that a small or mid account can actually rank in, matched to the post content and rotated to avoid spam patterns. Use to choose hashtags for a caption, carousel, or Reel. Not for writing the caption itself (use ig-caption-writer)
Chooses and applies the correct Kubernetes Pod Security Standard (Privileged, Baseline, Restricted) for a workload: what each profile forbids, how to map existing workloads to a profile, which securityContext fields must change, and how to plan a PodSecurityPolicy-to-PSS migration without breaking running pods. Use when deciding which pod security profile a namespace or workload should run under, auditing which workloads would fail Restricted, planning a PSP migration, or mapping pod security posture to a compliance control. Keywords: Pod Security Standards, PSS, Privileged, Baseline, Restricted, securityContext, runAsNonRoot, drop ALL capabilities, seccomp RuntimeDefault, PSP migration. Do not use for configuring the admission controller that enforces these profiles - use implementing-pod-security-admission-controller.
Use to assess the software architecture of a codebase, a module, or the current branch's changes against quality attributes and design principles (coupling/cohesion, layering/hexagonal adherence, separation of concerns, scalability, maintainability, testability). Produces a traceable assessment report with rated findings and prioritized recommendations. Invoke standalone to audit a system or design, or from another flow (incu-way-development at planning, incu-way-docs, incu-way-init) to evaluate a proposed or existing design before committing to it. Especially important before a large change, a refactor decision, or when tech debt and structural risk need to be made explicit.
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.
