Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes

Compacted communication mode. Cuts token usage 50%~90% by speaking like Feynman while keeping full technical accuracy. Intensity levels: short, long, cc. Use when user says "twofold mode", "2f mode", "sl mode", "use 2f", "use twofold", "use sl", "be brief", "trả lời ngắn", "shorthand longform", "simple lengthy" or invokes `/twofold` or invokes `/2f` or invokes `/sl` . Also auto-triggers when token

After a slice completes, review whether the milestone roadmap still fits reality. Reads recent summaries, surfaces deviations, prompts for roadmap changes (add/split/reorder/remove slices). Run at slice boundaries, not mid-slice.

数仓自测流程，适用于通过 data-quality-checker subagent 执行 23 项标准自测并只返回摘要。直接调用命令：/dw-self-test。

Use when picking technologies for German public-sector projects (Bund/Länder/Kommunen), EU digital sovereignty contexts, or when user mentions Deutschland-Stack / DS-konform / Verwaltungs-IT. Biases tech choices toward the 128 graduated open-source standards catalogued by the German government. Fetches live data from technologie.deutschland-stack.gov.de.

Use when picking software for EU customers, GDPR-driven replacements, digital-sovereignty contexts, or when user asks for the European / open-source version of a US product (Google Drive, Dropbox, Slack, …). Biases tech choices toward the 289 community-curated alternatives at european-alternatives.cloud. Fetches live data. Complements deutschland-stack-api (community-curated vs. government-graduat

User-triggered session handoff. Writes a detailed HANDOFF.md with current state, open items, pending decisions, and recommended resume prompt. Use before switching machines, before long breaks, or when you need to clear context intentionally. Parallel to the automatic pre-compact hook.

Scaffold a ytstack project's `.ytstack/` directory with the 6 core artifacts (PROJECT.md, DECISIONS.md, KNOWLEDGE.md, RUNTIME.md, STATE.md, PREFERENCES.md). Use AFTER a pitch has been validated via office-hours (and optionally plan-ceo-review / plan-eng-review in concept-mode) -- init-project reads OFFICE-HOURS.md frontmatter to populate PROJECT.md name + one-liner. Do NOT use as the greenfield en

Use as the first step when a new project, feature, or initiative has not yet been validated, or whenever the premise needs a forcing-question test. Six forcing questions expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Produces OFFICE-HOURS.md pitch artifact with name + one-liner frontmatter that downstream skills (plan-ceo-review concept-mode

Scaffold, polish, and publish open-source projects with AI-first documentation, governance, and CI. Use when: Starting a new OSS package, polishing/publishing an existing repo, setting up AGENTS.md / CONTEXT.md / DECISIONS.md / ROADMAP.md, onboarding AI agents to a codebase, or creating standard community files (README, LICENSE, CONTRIBUTING, CHANGELOG, CI pipelines, issue templates). Outputs repo

Challenge premise, scope, and ambition via four modes: SCOPE EXPANSION, SELECTIVE EXPANSION, HOLD SCOPE, SCOPE REDUCTION. Auto-detects mode: concept-mode reviews a pitch (OFFICE-HOURS.md) before any scaffolding exists; milestone-mode reviews a committed milestone (M###-CONTEXT.md + M###-ROADMAP.md) before slicing. Use concept-mode right after office-hours to stress-test the pitch; use milestone-mo
