The Prototype Builder specialist for Headout's PM OS. Use this skill whenever a product change involves a user-facing experience update — a new flow, a redesigned page, a new component, a changed interaction — and the PM or team needs to visualize what it should look and feel like before writing a full spec or handing to design. Two sequenced modes: MODE A — Journey Map (annotated user journey: every screen state, decision point, edge case, interaction). MODE B — HTML Prototype (working, clickable prototype from the journey map). Always run A before B. Trigger for: "what should this flow look like", "mock up the UX", "I want to see how this works before writing the spec", "build a prototype of X", "walk me through the user journey", "something to show the design team", or any feature involving a user-facing experience change.

The Implementation Planner specialist for Headout's PM OS. Use this skill to convert an approved PRD and design into a detailed, engineer-ready (and coding-agent-ready) implementation plan. It produces a structured task breakdown with clear sequencing, per-task acceptance criteria, API contracts, state transitions, dependencies, and rollout strategy. The output of this skill is designed to be directly usable by Cursor (or any AI coding agent) as the authoritative source of truth for what to build and in what order. Trigger this skill when a PM says "write the implementation plan for this", "break this into engineering tasks", "create the tech breakdown", "what's the build plan", "prepare this for engineering handoff", or when a spec has passed L1 review and is ready for engineering pickup. The Implementation Planner requires a spec (ideally post-L1 review) as input. It can also incorporate a prototype and data insights brief if available.

Performs structured code reviews on TypeScript codebases covering correctness, type safety, async patterns, security, testing, and style. Use when reviewing TypeScript code, pull requests, or when asked to do a code review on a TypeScript or Node.js project.

Rewrite a user's prompt to reduce the chance it trips Claude Fable 5's server-side safety classifiers (cyber/bio guardrails that force-route to Opus 4.8 or return stop_reason "refusal"). Use when the user hands you a prompt that touches cybersecurity, auth, exploits, malware, pentesting, or other dual-use topics and asks to make it "Fable-safe", "guardrail-safe", "won't get flagged/refused/downgraded", or to rewrite it so Fable 5 won't block it.

Review Claude Code auto memory accumulated during a task and promote valuable findings to shared project config (CLAUDE.md, .claude/rules/, or global CLAUDE.md). Use this skill when finishing a branch, completing a task, wrapping up work, or anytime you want to review what Claude learned and decide what the team should know. Also use when the Stop hook reminds you about pending memory entries. Triggers on "triage memory", "review memory", "promote memory", "memory triage", "what did we learn", "clean up memory", "share learnings", "anything worth keeping", or when the user asks about knowledge accumulated during a session.

Summarize any video by analyzing both audio and visuals. Downloads via yt-dlp, extracts transcript (YouTube captions or Whisper), pulls scene-detected keyframes, and produces a multimodal summary with clickable timestamped YouTube links. Use this skill whenever the user wants to summarize a YouTube video, digest a talk or tutorial, get notes from a video, extract key points from a recording, or says things like "tl;dw", "summarize this video", "what's in this video", or pastes a YouTube URL and asks for a summary. Also triggers for non-YouTube URLs that yt-dlp supports.

Assess your AI fluency using Anthropic's 4D framework (Dakan, Feller & Anthropic, 2025). Scans Claude Code sessions, runs LLM-based behavior classification on all messages, asks a self-assessment questionnaire for 6 unobservable behaviors, and generates a visual HTML report with scores and actionable feedback. Use when "assess fluency", "AI fluency", "fluency report", "fluency assessment", "4D framework", or "how AI fluent am I".

Use when the user wants to narrate a demo, add voice-over to a screen recording, or create AI narration for a silent video. End-to-end pipeline that extracts frames, analyzes with parallel subagents, writes a word-budgeted voice-over script, generates TTS audio per act, and merges everything back.

Write contextual commits that capture intent, decisions, and constraints alongside code changes. Use when committing code, finishing a task, or when the user asks to commit. Extends Conventional Commits with structured action lines in the commit body that preserve WHY code was written, not just WHAT changed.

Write technical launch blog posts optimized for both traditional SEO and AI engine citation (AEO). Use this skill whenever someone asks to write a launch announcement blog post, a technical blog post for a product release, a changelog-style post, or any written content tied to a product launch that lives on a blog or docs site. Also trigger for "write the blog post for this launch," "draft the announcement," "I need a technical write-up for this feature," or any request to create long-form launch content. Covers post structure, technical writing, benchmarks, tutorials, SEO, and answer engine optimization (AEO/GEO).

Plan and execute multi-channel distribution for product launches across X/Twitter, Reddit, LinkedIn, Hacker News, and other platforms. Use this skill whenever someone asks to create a distribution plan, figure out where to post a launch, build a press list, set up internal amplification, or coordinate multi-channel promotion. Also trigger for "where should we post this," "how do we get the word out," or any request about promoting or distributing a product announcement. Covers channel strategy (with deep playbooks for Twitter, Reddit, and LinkedIn), post-launch retro, and building a repeatable distribution engine.

Diagnose revenue leaks, analyze willingness-to-pay, evaluate packaging and pricing, and identify expansion revenue opportunities. Use when a PM needs to improve conversion to paid, optimize pricing, reduce revenue churn, or find upsell and expansion opportunities.

Set up measurement and tracking for product launches, run post-launch retros with data, and build a launch analytics system. Use this skill whenever someone asks to track a launch, set up UTM parameters, measure launch performance, run a launch retro, analyze launch results, or build a dashboard for a product release. Also trigger for "how do we know if the launch worked," "what should we track for this launch," "set up UTMs for the announcement," or any request about measuring or evaluating a product launch. Covers pre-launch tracking setup, UTM conventions, per-tier KPIs, benchmark expectations, and retro frameworks.

Decompose a top-line metric into a quantified metric tree with mathematical relationships, size each node, and identify where the real leverage is. Use when a PM needs to understand what drives a metric, where to focus, or where NOT to focus.

Resend transactional email patterns, React Email templates, domain configuration, and webhook handling. Use when sending emails, building email templates, or configuring email delivery.

Prisma ORM schema design, migrations, client generation, and query patterns. Use when designing database schemas, writing migrations, querying data, or managing Prisma Client.

Manages Sanity CMS schemas, GROQ queries, dataset exports/imports, and Studio configuration. Use when updating Sanity schemas, running GROQ or Vision queries, exporting datasets, modifying content models, or configuring a headless CMS with Sanity.io.

Configure pipelines, set up local/remote caching, and run scoped tasks in a Turborepo monorepo. Use when you say: 'enable remote caching', 'optimize pipeline inputs/outputs', or 'filter builds to affected packages'.

Generates Supabase database migrations, writes RLS policies with auth.uid(), configures auth integration, and generates TypeScript types. Use when creating tables, writing migrations, configuring RLS, or implementing Supabase auth.
