Use this skill whenever the user wants to work with Obsidian in any capacity. This is the ONLY skill for Obsidian vaults, .base files, Obsidian Markdown, Obsidian plugins, and Obsidian Web Clipper. Trigger for: creating or editing notes with wikilinks, callouts, embeds, or frontmatter; building or debugging .base files (formulas, filters, views, YAML quoting); Obsidian plugin development or hot-reload; Web Clipper JSON templates or AI Interpreter prompts; vault structure, daily notes, or the obsidian CLI. Also trigger when the user describes Obsidian-specific problems without naming Obsidian — like .base YAML errors, foldable callout syntax, base formula for tasks due this week, or clipper template for arxiv. Do NOT trigger for Logseq, Notion, Dataview plugin queries, generic markdown processing scripts, or general-purpose Chrome extensions.

Vercel AI Gateway expert guidance. Use when configuring model routing, provider failover, cost tracking, or managing multiple AI providers through a unified API.

Shape an article as a journey of beats, choose-your-own-adventure style. The user picks a starting beat from the raw material, you write only that beat, then offer options for where to pivot next, beat by beat, until the article reaches a natural end. Use when the user has raw material and wants to assemble it as a narrative rather than an argument.

Excel MCP Server skill for Windows workbook automation. Use when an assistant needs rich MCP tools to create, inspect, modify, format, or analyze Excel files. Supports Power Query (M), Data Model/DAX, PivotTables, Tables, Ranges, Charts, Slicers, formatting, screenshots, VBA macros, connections, and calculation mode. Triggers: Excel, spreadsheet, workbook, xlsx, xlsm, Power Query, DAX, PivotTable, chart, dashboard, VBA, MCP.

Extract durable working preferences from recent Cursor chats and convert them into skills, rules, or workflow docs. Use when asked to learn preferences, mine feedback, personalize workflows, or generate team/person-specific agent guidance.

Replace the client-side agent loop with Databricks Supervisor API (hosted tools + client-side function tools). Use when: (1) User asks about Supervisor API, (2) User wants Databricks to run the agent loop server-side, (3) Connecting Genie spaces, UC functions, agent endpoints, or MCP servers as hosted tools, (4) Mixing client-side function tools (Python callables your app executes) with hosted tools.

Implement GitOps workflows with ArgoCD and Flux for automated, declarative Kubernetes deployments with continuous reconciliation. Use when implementing GitOps practices, automating Kubernetes deployments, or setting up declarative infrastructure management.

Creates, configures, and updates Databricks Lakeflow Spark Declarative Pipelines (SDP/LDP) using serverless compute. Handles data ingestion with streaming tables, materialized views, CDC, SCD Type 2, and Auto Loader ingestion patterns. Use when building data pipelines, working with Delta Live Tables, ingesting streaming data, implementing change data capture, or when the user mentions SDP, LDP, DLT, Lakeflow pipelines, streaming tables, or bronze/silver/gold medallion architectures.

Creates complete AEM components with dialog, HTL template, Sling Model, unit tests, and clientlibs. Supports extending Core Components and project components. When a Figma design URL is provided, fetches the design via Figma MCP (get_design_context) and translates it into pixel-perfect HTL, CSS, and JS. Follows Adobe Experience League best practices for AEM Cloud Service and 6.5. Use this skill whenever the user mentions creating, building, generating, or scaffolding an AEM component, or mentions component types like teaser, card, hero, banner, accordion, tabs, carousel, list, navigation, breadcrumb, or any custom AEM component. Also trigger when the user wants to extend a Core Component, create a component dialog, add a Sling Model, or convert a Figma design into an AEM component.

Create or edit the Universal Editor component configuration (component-definition.json, component-models.json, component-filters.json) for AEM Edge Delivery Services blocks. Use this skill whenever the user mentions component models, component definitions, component filters, block configuration for the Universal Editor, UE block setup, adding a new block to UE, configuring block properties, block authoring fields, or any task involving the three JSON config files that control how blocks appear in the Universal Editor. Also trigger when the user wants to create a new EDS/Franklin block with UE support, modify block fields, add a block to the section filter, or asks about how blocks connect to the Universal Editor.

Runs 3 isolated reviewer sub-agents; consolidates PASS/BLOCK verdict by majority. Use when user requests independent review of code changes, pull requests, design documents, or release notes.

Use this skill to interactively debug Antithesis test runs using the multiverse debugger (MVD session). Open a debugging-session URL, inspect container filesystems and runtime state, run shell commands, and extract evidence from inside the Antithesis environment. Supports both the simplified debugger (default) and the advanced notebook mode.

Triage Antithesis test reports to understand what happened in a run: look up runs, check status, investigate failed properties (assertions), view metadata, download logs, inspect findings, and examine environmental details. Load after a run completes or when investigating a failure.

Use when authoring, creating, refining, or troubleshooting agent skills — scaffold SKILL.md and frontmatter, write and optimize the trigger description, structure the body with progressive disclosure, validate structure, and test or debug activation. Also when building a new skill from scratch, when a skill won't trigger, loads incorrectly, or the agent ignores it entirely. Use when a skill misbehaved in the current session and needs adjustment based on learnings.

Use for **any DSA question — interview prep OR day-to-day code work** — algorithm paradigms (BFS, Dijkstra, sliding window, monotonic stack, Union-Find, binary search, backtracking, topological sort, trie, DP), data structures (heap, segment tree, fenwick, trie), Java collection choice (HashMap/TreeMap, ArrayList/LinkedList, ArrayDeque/PriorityQueue, Comparator) while writing production code, graph primitives, complexity analysis, or refactoring existing code for better Big-O. Answers in Signal/Technique/Invariant/Complexity (STIC) card format; persists cards to a user-writable skill-state directory (see references/path-config.md). **Not for software design patterns** — use `design-pattern-practice`. Triggers on "classify this problem", "Java template for X", "shortest path", "HashMap vs TreeMap", "next greater element", "top K elements", "why is this loop slow", "is this O(N²)", "which collection should I use", "optimize this nested loop", "review this for algorithmic complexity".
