Industrial-strength NLP with spaCy 3.x for text processing and custom classifier training. Use when: installing spaCy, selecting models (en_core_web_sm/md/lg/trf), tokenization, POS tagging, named entity recognition, dependency parsing, training TextCategorizer models, troubleshooting errors (E050/E941 model errors, E927 version mismatch, memory issues), batch processing with nlp.pipe, or deploying models to production. Includes data preparation scripts, config templates, and FastAPI serving examples.

Sets up a new Rust/Python hybrid library project using maturin and uv. Creates project structure with PyO3 bindings, installs dev dependencies, and optionally configures git remote. Use when the user wants to initialise a Python library with Rust extensions.

Guide for creating and working in Git worktrees with a consistent workflow. Use when a user wants to run a task in a separate worktree, create or clean up worktrees, migrate a repo into a main/worktrees layout, or implement work based on an issue ID using GitHub/GitLab tooling.

Create GitHub issues from TASK-???.md files. Use when you need to bulk-create GitHub issues from task markdown files with frontmatter containing title, label, parent, and project attributes. Automatically extracts frontmatter, creates issues via gh CLI, links parent issues, and adds to specified projects.

Reviews finished and in-progress digital products to assess adherence to design specifications and discover potential issues with those specifications. Validates implementation against design intent, identifies visual and interaction discrepancies, and provides actionable feedback for design and engineering teams.

Build production-grade FastAPI backends with SQLModel, Dapr integration, and JWT authentication.Use when building REST APIs with Neon PostgreSQL, implementing event-driven microservices withDapr pub/sub, scheduling jobs, or creating CRUD endpoints with JWT/JWKS verification.NOT when building simple scripts or non-microservice architectures.

Integration patterns for combining Agent-to-Agent (A2A) Protocol with Model Context Protocol (MCP) for hybrid agent communication. Use when building systems that need both agent-to-agent communication and agent-to-tool integration, implementing composite architectures, or when user mentions A2A+MCP integration, hybrid protocols, or multi-agent tool access.

TLA+ formal verification for modeling and verifying concurrent algorithms and distributed systems.Use when asked about: TLA+, formal verification, model checking, verify algorithm, verify spec,check invariants, race condition analysis, concurrency model, TLC, Apalache, formal spec,temporal logic, prove correctness, state machine verification, model concurrent, TOCTOU,double-check locking, create TLA spec, run TLC, explain counterexample, verify safety,liveness property, deadlock detection, formal methods.Capabilities: Create specs from templates, run TLC/Apalache, generate CI pipelines,check code-spec drift, explain counterexamples, generate tests from invariants.

Master javascript ecosystem & es6+. Production-ready code examples, best practices, and real-world applications.

Generate and validate plugin manifest files (plugin.json, marketplace.json). Use when creating new plugins, updating manifests, adding plugins to marketplaces, or preparing for distribution.

Expert in managing YouTube content using YouTube Data API v3 and yt-dlp. **Use this skill whenever the user mentions 'YouTube', 'video download', 'playlist', 'YouTube videos', 'download from YouTube', or requests to list playlists, search videos, download videos, manage playlists, or any YouTube-related operations.** Handles authentication via OAuth, listing playlists (including Watch Later and Liked Videos), getting playlist items, downloading videos with yt-dlp, searching videos, getting video details, creating/deleting playlists, and adding/removing videos from playlists. (project, gitignored)

Implements persistent agent lifecycle management with 6 lifespans (ephemeral, turn, context, session, workflow, project). Use when creating agents that survive across turns, managing workflow-scoped execution, or needing automatic cleanup at lifecycle boundaries.

GitHub/Railway housekeeping for CI env/secret management and DX maintenance.Use when setting or auditing GitHub Actions variables/secrets, syncing Railway env → GitHub, or fixing CI failures due to missing env.

Load when working on data pipelines, datasets, reproducibility, or datainfrastructure topics. Contains best practices for data engineering,ETL/ELT patterns, and ensuring reproducible data workflows.

Use when planning animation workflows, deciding between spontaneous vs controlled approaches, or balancing creative freedom with structural precision.

Podcast production patterns and workflows. Use when recording podcasts, editing audio, transcribing episodes, generating show notes, RSS feed management, or podcast distribution.

Comprehensive diagnostic tool for troubleshooting OADP/Velero backup and restore problems with automated checks and recommendations.
