All Skills

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

Expert email writing skill for professionals and individuals. Use this skill whenever the user wants to write, draft, improve, or get help with ANY email — including cold outreach, follow-ups, complaints, negotiations, thank-you notes, difficult conversations, reconnection emails, or any other professional or personal email. Also trigger for email marketing requests: promotional offers, newsletters, welcome emails, re-engagement campaigns, or clickbait-style emails. Trigger for: "help me write an email", "draft an email", "how should I phrase this email", "I need to reach out to someone", "I need to follow up", "I want to send a thank you", "I have a complaint to write", "write a newsletter", "create a welcome email", "write a promotional email", "re-engage my subscribers", or any situation where someone needs to communicate via email. Do NOT limit this to obvious requests — if the user describes a situation where an email would be the right output, use this skill proactively.

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.

Rust documentation practices for HASH codebase. Use when writing doc comments, documenting functions/types/traits/modules, creating error sections, using intra-doc links, following rustdoc conventions, or exploring crate APIs with cargo doc.

Bidirectional conversion between Elm and Haskell. Use when migrating projects between these languages in either direction. Extends meta-convert-dev with Elm↔Haskell specific patterns. Use when migrating Elm frontend code to Haskell, translating Elm patterns to idiomatic Haskell, or refactoring Elm codebases. Extends meta-convert-dev with Elm-to-Haskell specific patterns.

Go-specific library/package development patterns. Use when creating Go libraries, designing public APIs with Go idioms, configuring go.mod, managing module versioning, publishing packages, or writing package documentation. Extends meta-library-dev with Go tooling and ecosystem practices.

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.

Build Retrieval-Augmented Generation (RAG) systems for LLM applications with vector databases and semantic search. Use when implementing knowledge-grounded AI, building document Q&A systems, or integrating LLMs with external knowledge bases.

Strategic search planning for agent-driven research. Generates structured search-term matrices with tiered fallback strategies, engine-specific operators, and grading criteria before executing any searches. Use this skill whenever research requires more than a single search query — comparing technologies, verifying claims across sources, surveying a landscape, investigating a multi-faceted question, or building evidence for a decision. Do NOT use for quick factual lookups, fetching a single known URL, or questions answerable from a single source. Covers tech, academic, regulatory, and general domains. Think of it as "research planning" — the matrix is the plan, execution comes after.

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.

Look up and apply the cooked, indexed proof playbook built from proof-material. Use when the user is proving a theorem, planning a proof, seeking reusable proof moves by task shape, assumptions, tags, desired move, or material source ID, or adapting cooked local moves and macro strategies with public source attribution.

Review Markdown prose against agent-style's 21 rules. `/style-review FILE` audits the file and (on user confirm) writes a polished copy at `FILE.reviewed.md`. `/style-review A.md B.md` A/B-compares two drafts and emits a per-rule delta table. Complements the generation-time rules installed via `agent-style enable <tool>`.

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.

21-rule prose review workflow for technical and academic Markdown/LaTeX excerpts. Use when the user asks for muxing-style-review, wants a complete agent-style check combining check-human.md with agent-style audit-only evidence, wants a compact-rule check, wants a DeepSeek/Codex manuscript draft checked for clarity, evidence, citation discipline, terminology, AI-tell prose, or wants an A/B draft comparison. Prefer a dedicated review subagent when available for non-trivial reviews. Use the sibling style-review skill for the upstream post-hoc audit/polish workflow.

Chrome-dependent academic paper fetching and BibTeX curation. Use when the user provides a planNN.md, paper list, citation list, or literature plan and wants Codex to use Google, Google Scholar, publisher pages, DBLP, arXiv, and the user's Chrome-accessible permissions to fetch the best available PDFs and create or update references.bib.
