Use this skill when working with Unreal Engine animation: AnimInstance, montage playback, blend space, state machine, anim notify, IK, AnimGraph, skeletal mesh, or linked anim graphs. See references/anim-notify-reference.md for notify patterns and references/locomotion-setup.md for locomotion setup. For montage integration with GAS, see ue-gameplay-abilities.
Invoke the `slack-cli` binary to read and act on a Slack workspace from the command line — list channels, read/search conversation history and threads, fetch unread messages, search users, manage user groups, post messages, add reactions, mark channels read, and manage saved items. Use whenever a task needs Slack data or actions, such as "what are the unread messages in
Spatial and spatiotemporal regression with GNNWR (Geographically Neural Network Weighted Regression). Use when Claude needs to: (1) Build spatially varying coefficient regression models, (2) Analyze geographic non-stationarity in spatial data, (3) Generate spatial coefficient maps for publication, (4) Run spatiotemporal regression with GTNNWR, (5) Scale geographically weighted regression to large datasets (N > 10k) with KNN mode, (6) Diagnose spatial model performance with F-tests, AIC, and residual maps.
Apply typography, color theory, spacing systems, and iconography principles to create cohesive visual designs. Use when establishing design tokens, building style guides, or improving visual hierarchy and consistency.
Create a standard PRD document package structure. Call it when starting a new project or initializing a PRD workspace.
Identify the core constraints that truly define a domain, profession, role, product, or debate. Classify these constraints into World/Rules/Interpretation (Hard/Soft/Self-imposed) categories, then analyze how this set of constraints defines identity, completes the problem statement, frames the solution space, and explains actual behaviors. It is particularly useful for distinguishing solution divergences caused by different constraints despite the same goal, and identifying old interpretations that are mistakenly treated as hard facts. USE WHEN the user says 'constraint', 'find constraints', 'what are the constraints of this domain', 'essential constraints', 'what defines its boundaries', 'is this a hard constraint or self-imposed constraint', 'where are the boundaries', 'why does this behavior happen', 'constraint', '/ljg-constraint', or provides any domain/profession/role/product/debate and requests mapping of its defining constraints and solution space. NOT FOR deep-dive generators (use ljg-rank, which focuses on generative power rather than boundaries), vertical deep dives into a single viewpoint (use ljg-think), book decomposition (use ljg-book), or concept dissection (use ljg-learn).
Generate EventSettings metadata to enable or disable Platform Tracing (TraceSpanEvent publishing) in Event Monitoring. Use this skill for any EventSettings enablePlatformTracing metadata work. TRIGGER when: user mentions Platform Tracing, TraceSpanEvent, enable tracing in Event Monitoring Settings, event monitoring tracing toggle, enablePlatformTracing, .settings-meta.xml for Event settings tracing, turn on trace span events, or stop publishing trace spans. DO NOT TRIGGER when: user wants Agentforce agent tracing to Data Cloud (use platform-tracing-agentforce-configure), wants Event Log Files or ELF generation, wants Change Data Capture (use integration-eventing-cdc-configure), or wants ManagedEventSubscription (use integration-eventing-subscription-configure).
Scaffold a new Rust+Node.js hybrid monorepo with pnpm workspaces, Cargo workspace, CI workflows, and publish infrastructure. Use when: (1) starting a new project from scratch, (2) adding missing infrastructure to an existing repo, (3) figuring out the canonical project structure for a Rust+Node.js tool. Triggers on "bootstrap", "scaffold", "new project", "set up project", or "init" in a Rust+Node.js context.
Merges mature lessons from a domain memory file into its instruction file. Syntax: `/memory-merger >domain [scope]` where scope is `global` (default), `user`, `workspace`, or `ws`.
Umbrella router for Graphistry workflows across SDK and API surfaces. Use to dispatch between Python SDK, REST API, and (future) JavaScript SDK workflows.
Databricks SQL query optimizer: analyzes a slow SQL query, rewrites it for speed using SQL-level optimizations only, validates byte-for-byte result equivalence, and benchmarks both versions with statistical significance testing. Use this skill whenever the user wants to optimize, speed up, tune, or benchmark a SQL query on Databricks. Trigger on: "/databricks-sql-autotuner", "optimize this SQL", "make this query faster", "tune my Databricks query", "benchmark SQL on Databricks", "speed up this spark SQL", "SQL performance on Databricks", "EXPLAIN this query", "why is my query slow on Databricks", "SQL query optimization Databricks", or whenever a user pastes a SQL query and mentions performance, slowness, or runtime.
End-to-end retail ETL pipeline using PySpark, SQL Server, and Medallion Architecture (Bronze/Silver/Gold layers) for data warehousing
