Teaches agents to iteratively build websites using Stitch with an autonomous baton-passing loop pattern

Convert frontend code (Vite, React, Angular, Vue, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React/Angular/Vue components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.

Extract a comprehensive design system (DESIGN.md) directly from frontend source code — React, Vue, Svelte, Angular, plain HTML/CSS, or any web framework. Analyzes component files, stylesheets, Tailwind configs, theme definitions, and design tokens to produce a rich, Stitch-compatible design system document. Use this skill whenever the user wants to reverse-engineer a design system from an existing codebase, audit the visual language of a project, extract design tokens from source files, or understand the styling patterns in a frontend repo — even if they just say "what does this app look like?" or "pull out the design from this code."

Extract self-contained static HTML from a built web application or React components by inlining CSS and images. Use this skill whenever you need to capture a specific UI state, share a static version of a page, or prepare assets for Stitch upload, even if the user just asks to 'save the HTML' or 'mock the view'.

Generate new screens from text prompts or images, edit existing screens with prompts and design system tokens, and generate design variants using Stitch MCP. Includes prompt enhancement pipeline, design mappings, professional UI/UX terminology, design tokens and theme system capabilities.

Manage design systems in Stitch using MCP tools. Includes retrieval of assets, creating/updating design systems in Stitch, and applying them to screens.

Converts Stitch designs into modular Vite and React components, or syncs/updates existing React components to align with the latest Stitch designs, using system-level networking and AST-based validation.

Convert Stitch HTML designs to React Native components, or syncs/updates existing native components to align with the latest Stitch designs, using StyleSheet.

Upload local assets (images, mockups, extracted HTML, design markdown) to a Stitch project. ALWAYS use this skill when you need to upload visual assets, HTML pages, or design docs to Stitch, particularly when direct MCP tool calls fail or truncate due to base64 token limits.

Analyze, research or value a listed stock or company (US, global, NSE or BSE) with verified data, ratios, scores and valuation. Use whenever asked if a stock is a buy, what it is worth, or how a company looks.

Manage a file-based epic → story → sprint development loop without requiring an external project management tool. Creates and tracks epics, breaks them into user stories, assigns them to sprints, and drives implementation story by story. Use when starting a new feature initiative or when the team has no Jira/Linear/Taiga but needs structured delivery tracking.

Use when teams pull in different directions, OKRs don't connect or departments optimize locally. Maps the strategy cascade and finds orphan goals and silos with alignment_checker.py.

Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.

Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction. Use when a session is approaching a context limit and a task phase is a natural place to compact.

Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction. Use when a session is approaching a context limit and a task phase is a natural place to compact.

Red-team a PRD, roadmap, or strategy by attacking its load-bearing assumptions before reality does. Steelmans then attacks each claim, ranks failure modes by impact × likelihood × cheapness-to-test, and returns the cheapest test and kill criteria for each. Use when stress-testing a plan, pressure-testing a strategy, challenging assumptions, or preparing a doc for executive review.

Stress-test a plan built on untested assumptions. Use whenever the user bets on a hockey-stick model or long pilot.

Use when the user says 'no hallucinations', 'verify APIs' or 'don't invent functions', or code depends on a library version you have not checked. Requires proof that every method, import and variable exists in the installed version before using it.

Query STRING API for protein-protein interactions (59M proteins, 20B interactions). Network analysis, GO/KEGG enrichment, interaction discovery, 5000+ species, for systems biology.

Build or review a Stripe integration with current Stripe guidance: Checkout Sessions, Payment Element, Setup Intents, subscriptions and the Customer Portal, webhook-driven fulfillment, idempotency, restricted API keys and Stripe Tax. Use when: stripe, payments, checkout, subscription, billing, webhook, refund, payment intent.

Use for any Stripe integration: subscriptions, trials, proration, checkout, usage billing, webhooks, customer portal or invoicing in Next.js, Express or Django. Writes idempotent webhook handlers and debugs delivery failures.

The director of Full Production Studio. Takes a raw video idea and runs it through the whole pipeline (idea → script → visual plan → motion → edit → captions → export), picking the right skill at every stage and keeping one project brief in sync. Use when the user wants to make a whole video end-to-end, says "make me a video/reel/short about…", "where do I start", "اعملي فيديو عن…", "عايز أعمل ريل", or is unsure which skill to use.

Use when independent bounded tasks benefit from delegation during implementation

Use when executing implementation plans with independent tasks in the current session

Use when executing implementation plans with independent tasks in the current session

Execute an implementation plan by dispatching a fresh subagent per task and reviewing each result in two stages — spec compliance first, code quality second — then a final integration review. Use when a plan already exists, tasks are mostly independent, and quality plus spec fidelity must hold between tasks. Not for discovering what to build, and not for one task you can finish in the current context.

Quietly suggest a concrete improvement after observing material, generalizable friction in agent work. Submit proactively without permission, preview, or announcement, then continue the primary task.

Summarize a customer interview transcript into a structured template with JTBD, satisfaction signals, and action items. Use when processing interview recordings or transcripts, synthesizing discovery interviews, or creating interview summaries.

Summarize a meeting transcript into structured notes with date, participants, topic, key decisions, summary points, and action items. Use when processing meeting recordings, creating meeting notes, writing meeting minutes, or recapping discussions.

Postgres performance optimization and best practices from Supabase. Use this skill when writing, reviewing, or optimizing Postgres queries, schema designs, or database configurations.

Use when several independent views can change a decision: a multi-domain design, uncertain cause, architecture tradeoff or blocker needing new evidence. Assign distinct evidence angles and let the accountable owner decide. Use direct single-agent work for a clear task and unblock for restoration that needs no additional view.
