Template for creating a new Agent Skill. Copy this folder, rename it to your skill's kebab-case name, and fill in every section. Use this as the starting point whenever you author a new skill for the AgentSkills library.

Designs and analyzes A/B tests end-to-end — frames a sharp hypothesis, computes required sample size and test duration, runs significance tests (two-proportion z-test, Welch's t-test, chi-square), reports confidence intervals and lift, and flags common pitfalls like peeking, multiple comparisons, and Simpson's paradox. Use this skill when the user mentions A/B testing, split testing, experiment design, conversion-rate experiments, statistical significance, p-values, sample size or power calculations, "did this experiment win", minimum detectable effect (MDE), or asks to interpret experiment results honestly. Includes a runnable stats script (scripts/abtest.py).

Works for technical, scientific, financial, or abstract topics.

Establishes a project's quality bar as a written contract and stops agents quietly lowering it. Interviews the user on which dimensions matter, supplies sane default thresholds when they have no number in mind, records everything in CONSTRAINTS.md, and watches the diff for a weakened bar — new @ts-ignore or eslint-disable suppressions, skipped or deleted tests, assertions stripped out, unimplemented stubs, thresholds edited down. Use when no quality bar is written down, when the user says "set up constraints" or "define our standards", when an agent keeps silencing checks or skipping tests to get to green, when you need a coverage or performance threshold and don't know what number to pick, or when an agent writes more code than anyone will read.

'Expert tutor that gets you from zero to working knowledge on any TOPIC fast, grounded in real sources rather than generic filler. Use this whenever the user wants to LEARN, understand, ramp up on, or get up to speed on something and has limited time: a new codebase or project they have been assigned, an unfamiliar technology or framework, a domain concept, an API, a paper, a business area. Triggers on phrases like "help me learn X", "I have N hours to understand X", "teach me X", "get me up to speed on X", "crash course on X", "quiz me on X", "make me a cheat sheet for X", "explain X like I am 5", "I got assigned X and have no context". Runs a timed 4-hour sprint by default, or a single mode on request (cheat sheet, learning ladder, quiz-me, Feynman loop, resource curation). Prefer this over answering a learning request directly, because the value is the structured, interactive, source-grounded teaching loop, not a one-shot dump.'

Builds, validates, explains, and previews cron expressions across Vixie/POSIX cron, systemd timers, and cloud schedulers, with explicit handling of timezones, DST, the day-of-month/day-of-week OR-logic trap, and overlap/missed-run pitfalls.

Systematically root-causes software bugs using a reproduce → isolate → hypothesize → bisect → verify methodology, replacing guess-and-check debugging with a disciplined, evidence-driven investigation. Use this skill when a user reports a bug, a test is failing intermittently or consistently, behavior differs between environments, a regression appeared after a change, something "used to work" and now doesn't, an error/stack trace needs root-causing, or when asked to "debug", "find the root cause", "figure out why X happens", or "track down" a defect. Triggers include crashes, wrong output, flaky tests, hangs/deadlocks, memory leaks, performance regressions, heisenbugs, and works-on-my-machine problems.
