Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Use when the user wants to optimize any form that is NOT signup/registration—including lead capture forms, contact forms, demo request forms, application forms, survey forms, or checkout forms. Also use when the user mentions “form optimization,” “lead form conversions,” “form friction,” “form fields,” “form completion rate,” “contact form,” “nobody fills out our form,” “form abandonment,” “too many fields,” “demo request form,” or “lead form isn't converting.” Use this for any non-signup form that captures information. For signup/registration forms, see signup-flow-cro. For popups containing forms, see popup-cro.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics
Generate documentation from existing code or prototypes. Triggers on: "document this", "reverse document", "generate docs from code", "onboard to codebase", "document existing system". Do NOT invoke for writing new design docs from scratch (use game-brainstorm or game-design-review). Part of the AlterLab GameForge collection.
Interactive SKILL.md builder. Use this skill whenever the user asks to "create a skill", "generate a skill", "scaffold a SKILL.md", "write a SKILL.md", or "turn this workflow into a skill" — even if they don't say "skill" and only describe wanting to make a repeatable agent workflow, checklist, or convention. Do NOT use for grading an existing SKILL.md (see rate-skill) or project roadmaps (see track-roadmap).
Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions. Use `gh` to inspect checks and logs, summarize the failure context, draft a fix plan, and implement only after explicit approval. Treat external providers (for example, Buildkite) as out of scope and report only the details URL.
Data persistence patterns in Go covering raw SQL with sqlx/pgx, ORMs like Ent and GORM, connection pooling, migrations with golang-migrate, and transaction management. Use when implementing database access, designing repositories, or managing schema migrations.
Cursor-native offensive security engagement and exploitability autoresearch orchestrator inspired by offensive-claude. Use for an authorized offensive engagement, red-team or pentest workflow, Kill Chain style assessment, scoped web/network/cloud/mobile/AD/bug-bounty offensive plan, or exploitability validation of defensive findings. In validate-findings mode it runs a bounded, user-controlled autoresearch loop over deduplicated findings: several hypothesis passes / cycles of hypothesize, experiment, observe, refine. Use it whenever the user asks to run an autoresearch loop, an iterative or multi-pass hypothesis loop, or to loop or iterate over findings for a set number of cycles. Supports engagement mode and validate-findings mode. Instruction-only: ships no scanners, exploit runners, payload builders, or local scripts.
Use when a task involves Halo CLI, Halo CMS command-line operations, or terminal-based Halo management. Also use when you need shared rules for profiles, JSON output, help discovery, config paths, and destructive actions. Trigger this skill whenever the user mentions 'halo', 'Halo CLI', or terminal operations for Halo CMS, even if the specific command area is not yet clear.
Translates vague user prompts into HeyEddi product docs (personas, route intent, voice), route-specific handoff artifacts (wireframes, user mockups, or briefs), and skill-routing under .heyeddi/. Use first on new projects before @heyeddi-design, @heyeddi-handoff, or @flutter-engineering. Never hand-write product.md: use write_product.

Apply these opinionated JavaScript conventions whenever writing or reviewing JS or Node: ESM-first packaging, choosing between Promise combinators, error handling that doesn't swallow failures, AbortController for cancellation, keeping the event loop unblocked, and reaching for platform APIs before dependencies.
Comprehensive guide for creating effective landing pages using Next.js or React. This skill should be used when users request to create landing pages, marketing pages, or product pages that require the 11 essential elements for high-converting landing pages. Specifically designed for Next.js 14+ App Router with ShadCN UI components.
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific proof obligation benefits from formal verification; use proof-writer for ordinary mathematical drafting
Create learning assessments including quizzes, exams, rubrics, and evaluation criteria aligned with learning objectives. Supports multiple question types, difficulty levels, and learning analytics. Use when the user asks to create quizzes, design tests, build grading rubrics, evaluate student learning, or generate assessment questions.
Amazon Multi-Channel Fulfillment (MCF) management for the new outbound fulfillment version. Use to get shipping offers and order previews, create, query, list, update, or cancel fulfillment orders, view packages and tracking, proof of delivery, delivery photos, recipient and locker/drop-off information, and query related invoice headers. Trigger when the user mentions Fulfillment Outbound, MCF, multi-channel fulfillment, fulfilling Amazon inventory to off-site customers, shipping offers, getOffers, getOrderPreview, createOrder, getInvoiceHeaders, receivedBy, unitIdentifiers, or v2026-07-04.

ONLY when the user explicitly wants a thorough, exhaustive, or comprehensive multi-source investigation or report that can run for minutes — due diligence, market landscapes, "compare X across many entities", verified fact-finding. ALSO read this when writing code that integrates the /v1/research endpoint (modes, reasoning depths, async polling). Slower and more expensive than linkup-search. For normal lookups and research use linkup-search instead; for bulk records from a page use linkup-extract. Uses Linkup's async /v1/research REST endpoint. Requires LINKUP_API_KEY.
When the user wants to build local backlinks, earn links from community organizations, or develop a local link building strategy. Also use when the user mentions "local links," "local backlinks," "community links," "sponsor links," "chamber of commerce link," or "local PR." For citation building, see local-citations. For content strategy, see local-content.
Discovers, enriches, and scores local businesses in any neighborhood using Nimble Web Search Agents (WSAs) and web data. Returns a structured, ranked list with confidence scores, reviews, social presence, and an interactive map. Use this skill when the user asks about local businesses, places, or neighborhood discovery.

Use when the user asks to "read/parse/open a document", uploads .doc/.docx/.xls/.xlsx/.ppt/.pptx/.pdf/.html files, or provides a URL.
Bring a project's formal verification back in line with the code after the code changes: find the commits that touched verified code, update the model, harness, or properties to describe the code as it is now, rerun, and say whether each failure is drift in the verification or a bug in the code. Use for /maintain-formal-verification-skill, \"is the model still true to the code\", or after merges and refactors that touched verified code without rechecking it.
This skill should be used when analyzing recent market-moving news events and their impact on equity markets and commodities.
