MUST consult this skill before answering whenever the user's task involves external versioned dependencies — even if you think you can handle it directly. This applies to: checking if packages/tools are up to date, upgrading npm/pip/cargo/go dependencies, planning or writing CI/CD workflows (GitHub Actions, CircleCI…
Turn any website into a fast, beautiful command-line client. Use when the user wants a CLI that replicates a site's features by capturing its network traffic (HAR), recovering the private/undocumented API behind it, and generating a typed terminal client that calls those endpoints directly instead of driving a browser…
Validate work in tasks-in-testing.md. Full acceptance criteria are in the task block. One item at a time, always sequential. Never fixes bugs, only flags and sends back.
When the user wants to reduce churn, build cancellation flows, set up save offers, recover failed payments, or implement retention strategies. Also trigger on "churn", "cancel flow", "cancellation", "save offer", "dunning", "failed payment recovery", "win-back", "retention", "exit survey", "pause subscription"…
A teaching aid that explains technical ideas with a small runnable code example and a guided walkthrough. It is meant for learning how something works, not fixing existing code.
Use when working in a coding project owned by a non-coder - when the project root contains CODESPLAIN.md, when the user invokes /codesplain (to bootstrap a project or ask a question), when a consequential technical decision comes up during building, or when explaining a bug or fix to the owner in plain language.
Focused SEO skills: keyword research, on-page and technical audits, AI-search optimization, traffic diagnosis, site-health triage, competitor and content audits, and programmatic SEO, with content companions.

Session orchestrator on top of the recall index of all Claude Code sessions: finds a past session by task description, dives in (context, project, skill, artifacts) and acts in one of three modes — finish here, hand off the resume command, or open the session in a new terminal window. Use when user asks: "find the…
Use when starting a coding session, making design decisions, fixing bugs, or when the user asks to remember or recall something — manages persistent memory via the mem CLI across project and global scopes.
Language-agnostic autonomous codebase improvement loop using isolated git worktrees. Every experiment runs on its own branch — main is never touched until a winning change is merged. Works with any language or framework.
