Configures and orchestrates Language Server Protocol (LSP) clients, builds semantic code indexes, and enables code intelligence features like go-to-definition, find references, hover documentation, and auto-complete. Use when you need to set up or debug language servers (e.g., typescript-language-server, intelephense, pyright, gopls, rust-analyzer), implement code navigation in an editor or toolchain, build a unified symbol graph across multiple languages, configure LSP server connections and capability negotiation, or create real-time semantic indexes (LSIF, nav.index.jsonl) for large codebases.

Monitors Excel spreadsheets (.xlsx/.xls) and extracts key sales metrics (MTD, YTD, Year End) to generate internal live reports. Use when the user needs to parse sales reports, track revenue figures, pull MTD/YTD data from a spreadsheet, build a sales dashboard, or automate extraction of sales performance data from Excel files into a database.

Builds native iOS and Android apps, creates cross-platform mobile applications using React Native or Flutter, configures mobile build systems, and debugs platform-specific issues including crashes, permissions, and store rejections. Use when the user asks about mobile app development, iOS or Android projects, Swift, SwiftUI, Kotlin, Jetpack Compose, React Native, Flutter, mobile UI design, push notifications, offline sync, in-app purchases, .ipa or .apk builds, or app store submission.

Creates browser-based AR/VR/XR experiences using the WebXR Device API, builds 3D scenes with Three.js, A-Frame, and Babylon.js, implements hand tracking, raycasting, hit testing, spatial anchors, and controller input, and applies performance optimizations like LOD, occlusion culling, and shader tuning for headsets and mobile AR. Use when the user asks about WebXR, virtual reality, augmented reality, immersive 3D web apps, VR headsets, spatial computing, or mentions frameworks like Three.js, A-Frame, Babylon.js, or file formats like .glb or .gltf.

Write structured Markdown documentation. Use when: creating a README, ADR, design doc, RFC, runbook, playbook, release notes, incident report, API doc, troubleshooting guide, FAQ, onboarding guide, contributing guide, changelog, user guide, meeting notes, Confluence page, JIRA ticket, or any technical document. Handles tables of contents, summaries, conclusions, comparison tables, decision matrices, glossaries, and diagram placeholders.

This skill should be used when working with genomic interval data (BED files) for machine learning tasks. Use for training region embeddings (Region2Vec, BEDspace), single-cell ATAC-seq analysis (scEmbed), building consensus peaks (universes), or any ML-based analysis of genomic regions. Applies to BED file collections, scATAC-seq data, chromatin accessibility datasets, and region-based genomic feature learning.

Breaks down complex software, writing, or research tasks into small, atomic, independently completable units with dependency graphs and milestone breakdowns. Use when the user asks to plan a project, decompose a feature, create subtasks, split up work, or needs help organizing a large piece of work into a step-by-step plan. Triggered by phrases like "break down", "decompose", "where do I start", "too big", "split into tasks", "work breakdown", or "task list".

Guides the red-green-refactor TDD workflow: write a failing test first, implement the minimum code to make it pass, then refactor while keeping tests green. Use when a user asks to practice TDD, write tests first, follow red-green-refactor, do test-driven development, write failing tests before code, or phrases like 'make the test pass', 'test coverage', or 'unit tests before implementation'.

Technical project management for Backlog.md workstreams using coordinated sub-agents. Use only when the user explicitly asks Codex to take over one or more existing Backlog.md tasks (for example: "act as TPM", "coordinate these tasks", "delegate to sub-agents"). Orchestrate planning, implementation, and finalization; manage dependencies and overlapping code areas; review and approve sub-agent plans before implementation.

Reviews test code to identify and fix common testing anti-patterns including flaky tests, over-mocking, brittle assertions, test interdependency, and hidden test logic. Flags bad patterns, explains the specific defect, and provides corrected implementations. Use when reviewing test code, debugging intermittent or unreliable test failures, or when the user mentions flaky tests, test smells, brittle tests, test isolation issues, mock overuse, slow tests, or test maintenance problems.
