OpenTelemetry SDK and package version lookup across languages. Use when choosing the latest compatible released OpenTelemetry SDK or package version and locating setup docs or examples.

This skill should be used when users request code review, refactoring, or code quality improvements for Ruby codebases. Apply Sandi Metz's four rules for writing maintainable object-oriented code - classes under 100 lines, methods under 5 lines, no more than 4 parameters, and controllers instantiate only one object. Use when users mention "Sandi Metz", "code quality", "refactoring", or when reviewing Ruby code for maintainability.

OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the OpenTelemetry Collector. Use when authoring or reviewing `transform`, `filter`, `tail_sampling` processor configs or `routing` connector configs, debugging OTTL syntax or semantics, transforming traces, metrics, logs, or profiles, or converting data-processing requirements into OTTL statements.

Diagnoses and fixes slow Neo4j Cypher queries by reading execution plans, identifying bad operators (AllNodesScan, CartesianProduct, Eager, NodeByLabelScan), and prescribing fixes (indexes, hints, query rewrites, runtime selection). Use when a query is slow, when EXPLAIN or PROFILE output needs interpretation, when dbHits or pageCacheHitRatio are poor, when cardinality estimation diverges from actuals, or when deciding between slotted/pipelined/parallel runtimes. Covers USING INDEX / USING SCAN / USING JOIN hints, db.stats.retrieve, SHOW QUERIES, SHOW TRANSACTIONS, TERMINATE TRANSACTION. Does NOT write new Cypher from scratch — use neo4j-cypher-skill. Does NOT cover GDS algorithm tuning — use neo4j-gds-skill. Does NOT cover index/constraint creation syntax details — use neo4j-cypher-skill references/indexes.md.

Wires the Aura Topbar (@aura/topbar) into Flows/Fusion apps as the single top navigation bar — breadcrumbs, optional center Tabs or Segmented control, right utility strip (Share, notifications, theme menu, Atlas, user Avatar), and light/dark theme switching. Use when adding a topbar, app header, navigation bar, breadcrumbs, or theme switcher to a Flows or Fusion app, or when scaffolding a new Flows/Fusion application.

Plan and execute product launches using a tiered framework — from major new products down to small improvements. Use this skill whenever someone asks to plan a launch, create a launch checklist, define launch tiers, write launch messaging, or coordinate a product release. Also trigger when someone says "we're launching X" or "how should we announce this feature" or "what's our launch plan" — even if they don't use the word "strategy." Covers messaging, naming, launch assets, timelines, and post-launch retros. This is the master launch skill; it references the companion skills (launch-tweet, launch-landing-page, launch-distribution, launch-email, launch-video, launch-metrics) for specific execution.

Deploy sites, configure serverless and edge functions, and verify builds on Netlify. Use when the user mentions: 'deploy preview', 'configure netlify.toml', or 'debug a failed deploy'. Trigger terms: build error, Netlify Functions, deploy logs, deploy preview

Fast in-memory DataFrame library for datasets that fit in RAM. Use when pandas is too slow but data still fits in memory. Lazy evaluation, parallel execution, Apache Arrow backend. Best for 1-100GB datasets, ETL pipelines, faster pandas replacement. For larger-than-RAM data use dask or vaex.

Find Key Opinion Leaders (KOLs) in a given domain by combining web research with LinkedIn post search. Given a company/idea and target domain, generates authority keywords, searches LinkedIn posts to find prolific authors with high engagement, and merges with web-researched influencers. Use when someone wants to "find influencers in X space" or "who are the KOLs for Y industry."

Run the mandatory pre-push baseline verification for Meshtastic-Android — bootstrap, then spotlessApply/spotlessCheck/detekt/assembleDebug/test/allTests (plus kmpSmokeCompile and sort-strings when relevant) via the gradle-runner subagent, restore the host-render screenshot diff, and report a single pass/fail. Use before every push. This is the check CI fails on when skipped.

Scroll mouse wheel in specified direction. When you need to scroll page/document content, navigate long lists, or zoom in/out with Ctrl. Directions - up/down/left/right.

Execute keyboard shortcuts. When you need to copy/paste (Ctrl+C/V), save files (Ctrl+S), close windows (Alt+F4), undo/redo (Ctrl+Z/Y), or select all (Ctrl+A).

Find desktop UI elements using UIAutomation (fast, accurate) or vision recognition (fallback). When you need to locate buttons/menus/icons, get element positions before clicking, or verify UI state. For browser webpage elements, use browser_* tools instead.

Click desktop elements or coordinates. When you need to click buttons/icons in applications, select menu items, or interact with desktop UI. Supports element description, name prefix, or coordinates. For browser webpage elements, use browser_click instead.

Create, edit, review, and finalize editable Microsoft PowerPoint .pptx presentations. Use for new decks, source- or template-based presentations, targeted slide edits, charts, tables, images, speaker notes, visual QA, and legacy .ppt conversion. Do not use for HTML/browser presentations, Google Slides, or live Microsoft PowerPoint control.

Investor-first workflow for reviewing an existing financial model, forecast, or sensitivity analysis. Use for prompts like "review this model", "stress test these assumptions", "what breaks in this forecast", or "is this model decision-ready". Best when you have a spreadsheet export, pasted assumptions, key drivers, and the decision the model supports. Optional Open Brain search and capture can pull prior model context and store the final review memo.

Scaffold a langchain-oracledb store layer — multi-collection OracleVS wrapper, metadata-as-string monkeypatch, embedder-dim assertion, OracleChatHistory subclass (langchain-oracledb does not ship one). Use when a project needs Oracle as its LangChain vector store and chat-history backend.

Write PR titles and descriptions the way a staff engineer would. Use when drafting or editing a pull request title and body, before running `gh pr create`, or any time the user asks for a PR description, summary, or release-notes-style writeup of a change. Apply this skill from the start, not as a cleanup pass after a generic first draft.

Generate beautiful interactive timeline HTML pages from JSON data, with vertical, horizontal, or dual-side layouts, collapsible details, and custom colors. Ideal for project milestones, company histories, or resumes. Triggered when a user mentions 'timeline', 'history of events', 'project milestones', 'release log', or asks to visualize a chronological sequence of data.
