Encode and decode Swift types to and from JSON, property lists, and other external representations using Codable, JSONEncoder, and JSONDecoder. Use when implementing API response parsing, custom CodingKeys for key remapping, custom init(from:) or encode(to:) for complex transformations, nested or flattened JSON structures, heterogeneous array decoding, date and data decoding strategies, lossy array wrappers, Codable integration with URLSession, SwiftData, or UserDefaults, or when configuring encoder/decoder output formatting and key strategies.
Advise startup founders on choosing the best jurisdiction and legal entity for their business. Triggers when users ask about where to incorporate, which state/country to register a company, choosing between Delaware vs other states, offshore vs US incorporation, entity types (C-Corp, LLC, PBC), or jurisdiction selection for specific industries (crypto, AI, SaaS, GameDev, solopreneurs). Also triggers for questions about startup formation, company registration, or corporate structure decisions.
Profile-aware speech workflow for narrated notes, spoken drafts, audio summaries, accessibility reads, and other text-to-speech tasks. Use when one front-door workflow should resolve voice profiles, enforce disclosure, and apply manifest tracking before delegating to built-in `$speech` or a deterministic local CLI path.
Remove signs of AI-generated writing from text. Use when editing or reviewing any content to make it sound more natural and human-written. Catches patterns like inflated language, rule of three, em dash overuse, vague attributions, copula avoidance, negative parallelisms, synonym cycling, filler phrases, excessive hedging, and soulless structure. Use when someone says "humanize this", "this sounds like AI", "make this sound human", "remove the AI", "clean this up", "de-AI this", "this reads like ChatGPT", or when reviewing any AI-assisted draft before publishing. Also use as a final pass on content from other skills like boring-remix or social-content. World Code integrated — applies voice.md rules when available.
Create a comprehensive brand identity document that other skills can reference. Use this wizard before running newsletter, podcast, or content skills that need brand context. Outputs a brand-identity.md file with persona, voice, audience, values, and messaging.
Use when implementing data analysis pipelines, statistical tests, or bioinformatics workflows in code (Python/R), particularly for genomics, transcriptomics, proteomics, or other -omics data.
Simulate a senior high school grade 3 science tutor in China, using progressive teaching methods to tutor math, physics, chemistry, biology and other science problems. Used when students ask science questions, request explanations, say "I don't understand" or "Teach me". Suitable for Gaokao preparation, problem-solving guidance, and concept understanding.
Modern Git command best practices for AI agents. Use modern, purposeful commands introduced in Git 2.23+ instead of legacy multi-purpose commands. Teaches when to use `git switch` (branch operations), `git restore` (file operations), and other safer alternatives to improve clarity and reduce errors.
Iteratively improve any output until measurable criteria are met. Use when the user wants to refine existing work against specific standards — whether it's code, prose, data, config, or any other artifact. Triggers on phrases like "improve this", "make it better", "iterate", "refine", "keep improving", "not good enough yet", "optimize this", "polish this", "tighten this up", or when the user provides criteria and wants repeated improvement until they're satisfied. Also use when the user gives feedback on output and expects you to keep refining, even if they don't say "improve" explicitly.
ALWAYS invoke this skill at the START of every session before doing any other work. Validates project health: governance rules, tool availability, memory directory, settings files, script permissions, .agents directory, and .beads/.gitignore hygiene. Remediates issues across all swain skills. Idempotent — safe to run every session.
Build TypeScript clients for SpacetimeDB. Use when connecting to SpacetimeDB from web apps, Node.js, Deno, Bun, or other JavaScript runtimes.
Optimize code performance through iterative improvements (max 2 rounds). Benchmark execution time and memory usage, compare against baseline implementations, and generate detailed optimization reports. Supports C++, Python, Java, Rust, and other languages.
