Coding & Dev Tools

Use when implementing trpc functionality with production-grade patterns and safeguards.

Expert content repurposing skill for creators and professionals who want to get more out of content they've already created. Use this skill whenever the user wants to turn one piece of content into multiple formats — for example: turning a blog post into social media posts, converting a YouTube video or podcast into a newsletter or article, transforming a long-form piece into short clips or quotes, or adapting any content for a different platform or audience. Triggers: "repurpose this", "turn this into a post", "make a LinkedIn post from this", "convert this blog to a tweet thread", "I have a video/podcast, can you make it into a newsletter", "get more out of this content", "adapt this for [platform]", or any request to transform existing content into a new format. Do NOT limit to obvious repurposing requests — if the user shares content and mentions another platform or format, use this skill.

Foundational Python patterns covering core syntax, idioms, type hints, testing, and modern tooling. Use when writing Python code, understanding Pythonic patterns, working with type hints, or needing guidance on which specialized Python skill to use. This is the entry point for Python development.

Convert Java code to idiomatic C++. Use when migrating Java projects to C++, translating Java patterns to idiomatic C++, or refactoring Java codebases. Extends meta-convert-dev with Java-to-C++ specific patterns.

Develop reusable library code across languages. Use when designing public APIs, organizing modules, managing versioning, or creating utility libraries. Provides foundational patterns that language-specific *-lib-* skills extend.

Bidirectional conversion between Roc and Scala. Use when migrating projects between these languages in either direction. Extends meta-convert-dev with Roc↔Scala specific patterns. Use when migrating Roc projects to JVM/Scala, translating pure functional patterns to object-functional hybrid, or refactoring Roc codebases. Extends meta-convert-dev with Roc-to-Scala specific patterns.

Bidirectional conversion between Elixir and Roc. Use when migrating projects between these languages in either direction. Extends meta-convert-dev with Elixir↔Roc specific patterns. Use when migrating Elixir projects to Roc, translating BEAM/OTP patterns to platform-based architecture, or refactoring Elixir codebases. Extends meta-convert-dev with Elixir-to-Roc specific patterns.

Convert Objective-C code to idiomatic Swift. Use when migrating Objective-C projects to Swift, translating Objective-C patterns to modern Swift, modernizing legacy codebases, or establishing gradual migration strategies with interop. Extends meta-convert-dev with Objective-C-to-Swift specific patterns including bridging and @objc attributes.

Develop OpenFeature SDK implementations from the specification. Use when implementing the OpenFeature spec in a new language, extending existing SDKs with new features, building custom providers, or contributing to official SDK repositories.

C++-specific library development patterns. Use when creating C++ libraries, designing header-only vs compiled libraries, configuring CMake for library targets, managing ABI stability and versioning, integrating with Conan/vcpkg, documenting with Doxygen, or testing with GoogleTest/Catch2. Extends meta-library-dev with C++ tooling and idioms.

Bidirectional conversion between Erlang and Fsharp. Use when migrating projects between these languages in either direction. Extends meta-convert-dev with Erlang↔Fsharp specific patterns.

Store and inspect source-indexed proof material extracted from papers, notes, PDFs, or LaTeX sources. Use when Codex needs stable material IDs, source locations, reusable abstractions, proof skeletons, tags, and public attribution before any proof ideas are cooked into proof-usage.

Inventory Items in a Fabric Workspace

Delete a Fabric Workspace (with safety hook)

Unified Diary System: A context-preserving automated logger for multi-project development.

Rewrite the previous response more briefly while preserving the substance.

Interact with GitHub issues - create, list, and view issues.

Scanpy is a scalable Python toolkit for analyzing single-cell RNA-seq data, built on AnnData. Apply this skill for complete single-cell workflows including quality control, normalization, dimensionality reduction, clustering, marker gene identification, visualization, and trajectory analysis.

Modern Angular (v20+) expert with deep knowledge of Signals, Standalone Components, Zoneless applications, SSR/Hydration, and reactive patterns.

Use HasData APIs for web scraping and structured web data extraction.

Human-in-the-loop web studio to tune AI-generated output by eye. Stand up a local interactive studio (sliders, pickers, drag handles) or an inline edit/highlight/comment annotation studio for prose & media, instead of guessing values or shipping a static comparison grid.

When the user wants help with pricing decisions, packaging, or monetization strategy. Also use when the user mentions 'pricing,' 'pricing tiers,' 'freemium,' 'free trial,' 'packaging,' 'price increase,' 'value metric,' 'Van Westendorp,' 'willingness to pay,' 'monetization,' 'how much...

Design user flows and navigation structure following proven UX patterns

Ask which skill or flow fits your situation. A router over the user-invoked skills in this repo.

Configure and maintain Python projects, dependencies, packaging, environments, linting, formatting, type checking, testing, builds, and publishing. Use for pyproject.toml, an existing repository toolchain, or repository-level Python tooling work, not for a standalone script.

Use to build a data-subject erasure plan for support conversations — GDPR right to erasure, CCPA deletion, right to be forgotten. Trigger for "delete this customer's data", DSR or SAR erasure request, GDPR deletion from our helpdesk, redacting personal data from tickets, or working out what can and cannot be erased.

Use to find the activation blockers visible in support contacts from new customers, before they show up in retention numbers months later. Trigger for "why aren't new customers activating", "what do new customers contact us about", onboarding drop-off, time-to-value analysis, first-90-days support experience, or a retention problem that traces back to activation.

Use to quantify what support quality failures cost — rework, credits, escalation handling, complaints and churn — with the causal limits stated. Trigger for "what do our quality failures cost", "cost of rework in support", "business case for improving quality", "how much is bad support costing us", or a quality investment that needs a number attached.

Use to run customer support communications during an outage or major incident — banners, macros, status page, volume planning, and postmortem inputs. Trigger for "incident comms playbook", "support during outage", status page and help centre banner, macro for widespread issue, staffing surge, or freeze non-incident work.

Use to analyse touch time vs elapsed time across the resolution path — queue wait, customer wait, back-office wait, and where elapsed time hides real delay. Trigger for "flow efficiency", "touch time vs elapsed time", "where is the time going", "customers waiting on us", back-office bottlenecks, idle time in cases, or end-to-end time much longer than handle time.
