Guides systematic root-cause debugging. Use when tests fail, builds break, something that worked yesterday broke, behavior doesn't match expectations, or you encounter any unexpected error. Use when you need to figure out what broke and why — a systematic approach to finding and fixing the root cause rather than guessing.

Live stream as an AI VTuber on Lobster.fun.

Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.

Securely transfers files from macOS to Android with checksum verification and path validation.

Answer SRS (Simple Realtime Server) questions for developers and users — protocols, configuration, architecture.

Adversarial self-improvement for AI agents.

AI agent for teamo lite tasks.

Build agent-facing web experiences with ATXP-based.

Iterate on the Cardputer-Adv MicroPython app bundle (Antigravity Buddy, Snake, Hello) after the device is already provisioned via m5-onboard. Use when the user wants to add a new app, push a single changed .py without re-flashing, watch device serial logs, or run a one-shot REPL command. Trigger on "add an app", "push to the cardputer", "tail the device", "run on the device", or follow-up work after /maker-setup.

this file is the canonical, reviewable skill instructions (no dynamic loading).

Validate a business idea before investing time or money.

Universal service integration for OpenClaw — connect Reddit, Steam, Spotify, GitHub, Discord.

Free simple invoice generator.

Autonomous iterative experimentation loop for any programming task. Guides the user through defining goals, measurable metrics, and scope constraints, then runs an autonomous loop of code changes, testing, measuring, and keeping/discarding results. Inspired by Karpathy's autoresearch. USE FOR: autonomous improvement, iterative optimization, experiment loop, auto research, performance tuning, automated experimentation, hill climbing, try things automatically, optimize code, run experime

Use this skill when the user asks to analyze, tear down, or reverse-engineer a competitor's paid ads. Trigger for prompts like "what ads is [competitor] running", "tear down their ad strategy", "competitor ad analysis", "find ad angles we haven't tried", or "reverse-engineer their paid funnel". Do not trigger for organic/SEO competitor research or website positioning analysis.

Guard against destructive operations with three modes: Careful intercepts dangerous commands (rm -rf, git push --force, DROP TABLE) for confirmation, Freeze locks writes to one directory, and Guard combines both. Advisory: the agent applies these rules itself; no hook ships with it. Use when working on production systems, running agents autonomously, restricting edits to a directory, or during migrations, deploys, and data changes.

Dating platform for AI agents — register, match, chat, fall in love, and start drama.

Extract a color palette from an image and return HEX/RGB values with optional swatch image.

Extract closed captions and subtitles from YouTube videos.

Get a quick summary of the current Git repository including status.

Generate and send a 5-day Tübingen weather graphic (PNG) from open-meteo.com.

AI Life Simulator - Experience infinite lives year by year.

Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when you want every assumption cross-examined before proceeding, when stress-testing a plan for hidden failure modes, when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production auth, security-sensitive logic, a high-stakes migration, irreversible operations), or any time a confident output would be cheaper to verify now than to debug later.
