product-on-purpose Bundle

Day 2 (Tuesday) move of a Design Sprint that structures lightning demos and the four-step independent solution sketch protocol (Notes, Ideas, Crazy 8s, Solution Sketch). Each team member produces one solution sketch individually; the skill orchestrates the day but does not author the sketches themselves. Use Tuesday morning after Monday's target moment is locked. Output is the lightning demo board, sketch assignments, and the cohort of independent sketches that become Wednesday's heat-map material.

product-on-purpose Bundle

Specifies what analytics events to track, when they fire, and what properties to include, as a contract between product and engineering that prevents undertracked features. Use before engineering builds a feature or when auditing existing tracking for gaps. For the dashboard built on top of these events, use measure-dashboard-requirements instead.

social-media-skills Bundle

Content recycling — resurface, update, and repost proven evergreen content over time. Use when someone wants to "get more mileage out of old posts," "recycle/repost our best content," "resurface evergreen pieces," "update and republish an old post," or build a recycling queue of proven winners. Recycles the INSIGHT refreshed (new hook/format/updated data) on a deliberate cadence — never an identical repost. Distinct from cross-platform-repurposing (same moment, many platforms) and captions-and-clipping (long-form -> short clips). Reads brand-profile + voice-builder first. The agent drafts the refresh; a human reviews; WoopSocial schedules/publishes (delete+recreate, no update); winners are picked from native analytics; nothing is fabricated.

social-media-skills Bundle

Use to plan and produce a full batch of social media content for a period — a week or a month — in one session: strategically balanced, on-brand, mapped to a calendar, and ready to schedule. Run when the user says "plan my content," "a month of posts," "batch my content," "plan the week," "fill my calendar," or wants many posts planned at once in one sitting. Reads brand-profile, voice, and content-pillars first, and produces a brief for each post that the content skills (caption-writer, reels-script, hook-writer) execute. As a BRIDGE skill it then confirms and hands the batch to scheduling-and-queue. Builds a balanced mix — never all-promotion — matched to the user's real capacity. Suggests cadence but does not claim analytics-based timing (WoopSocial has no analytics surface yet). For the ongoing recurring system — which pillars/formats post on which days, the living "content calendar" — use content-calendar; this skill fills one specific period of that system with actual post briefs.

social-media-skills Bundle

Use to build a genuine community — turning an audience into people who interact with each other, not just with the brand. Run when the user asks how to build community, foster belonging/loyalty, create superfans, start a group/Discord channel, get members talking to each other, or move beyond chasing followers/virality. Reads brand-profile/social-strategy/audience-research. Community outperforms virality, measured by relationship depth/retention, not follower count. Covers the audience-to-community distinction (member-to-member interaction), choosing the space (in-feed -> semi-owned -> owned groups/Discord), recurring rituals, building belonging, and nurturing superfans into advocates. KPIs read natively, never fabricated. Advisory: WoopSocial schedules the content but does NOT run Discord/Slack or show analytics — the human runs the community, the agent drafts. Never fake community; get consent before spotlighting. Pairs with reply-and-comment-writer and crisis-and-moderation.

social-media-skills Bundle

Use to optimize a social media profile so it converts visitors into followers and followers into leads — bio, handle, name/headline field, profile picture, banner/header, link-in-bio, CTA, pinned posts, and highlights. Run when the user says "optimize my profile/bio," "write my bio," "my Instagram/LinkedIn/TikTok bio," "profile," "link in bio," "my profile isn't converting," asks about creator mode or a professional/business account, or wants their account to convert better. Reads brand-profile, voice, audience, and social-strategy first. Treats the profile as a conversion landing page — 3-second clarity, searchable-field keywords, a who/what/why bio with one CTA, a goal-matched link, and specs for the visuals, pinned posts, and highlights. Advisory: produces a ready-to-apply per-platform spec (WoopSocial publishes posts/media; it does not edit profile fields). Judges results via native profile insights, not WoopSocial analytics.

social-media-skills Bundle

Use to schedule, queue, or publish FINISHED social media posts to the user's connected accounts through WoopSocial. This is a BRIDGE skill — it turns ready content into real scheduled or published posts, the step that separates advice from action. Run when the user says "schedule this," "queue these," "post this," "publish to my channels," "add to my calendar," "schedule for [time]," "fan this out to all platforms," or right after a content skill has produced posts that are ready to go out. ALWAYS confirms before scheduling or publishing. If WoopSocial isn't connected, it produces a ready-to-use schedule and explains how to connect — it never pretends to post. It does NOT write content (use the content skills) or report analytics (WoopSocial has no analytics surface yet).

social-media-skills Bundle

Use to reverse-engineer why a piece of content went viral (or overperformed) — yours or someone else's — and extract the repeatable mechanism to apply to your own content. Run when the user says "why did this go viral," "break down this viral post/video," "reverse engineer," "what made this work," or wants to learn from viral content. Sources the observable signal first (intake, transcript, screenshots, top comments, visible stats — an agent usually can't watch a video from a link) and never fabricates what it can't see. Reads brand-profile and audience first, deconstructs the piece layer by layer, isolates the real driver, runs a replicability check, extracts the transferable principle, and applies it to the user's niche via the content skills. Mechanism, never a copy; flags non-replicable virality; visible signals only (no WoopSocial analytics). Single-POST teardown only: for the account-level competitive landscape use competitor-analysis; for riding a live trend use trend-jacking.

social-media-skills Bundle

A/B testing and experimentation for social media content — evidence over opinion, at honest organic-scale rigor. Use when someone wants to "A/B test" or "split test" content, "test which version/hook/time/caption/thumbnail works," "set up an experiment," "what should I test," or to settle a content debate with evidence instead of opinion. Designs disciplined organic tests: one variable, controlled context, a decision rule set BEFORE publishing, enough duration and repetitions to separate signal from noise. Uses the TEST framework. Reads brand-profile + goals-and-kpis first. It DESIGNS the test and drafts variants; WoopSocial schedules them as controlled sequential posts (exception: YouTube's native Test & Compare); the result is read from native analytics via analytics-and-reporting. Organic can't reach true statistical significance; nothing is fabricated or p-hacked. Distinct from analytics-and-reporting (measures) and goals-and-kpis (sets targets).

guanyang-open-agent-hub Bundle

Stop and check this skill before finishing any reply to a question about how to use Claude or a Claude product — it recommends matching courses, tutorials, and use cases from Claude Academy (academy.claude.com), Anthropic's learning hub. Trigger on: "how do I", "how can I", "getting started with", "what can Claude do", "teach me", "learn to use"; questions about artifacts, projects, skills, plugins, connectors, MCP, Claude Code, Claude Cowork, Claude in Excel, Claude in PowerPoint, Claude in Chrome, the Claude API, or prompting technique; requests about rolling Claude out to a team, class, or organization; and any ask for training materials, onboarding content, or learning resources. Use it when the user is learning how to use a feature or product — not when they are mid-task and just want the task done. This skill composes with other skills: after consulting product documentation to answer how a Claude feature works, also check here for a matching course or tutorial — a docs-grounded answer and an Academy re
