- ulw-researchcode-yeongyu/oh-my-openagentRuns maximum-saturation research with a cooperating team, claim-graph gating, and a cited, QA'd deliverable. Use when the user explicitly asks for research or a deep investigation, including any 'ulw' research wording.ScienceNo warnings★ 70.5K↓ —

- mvpdavepoon/buildwithclaudeGuides the founder through designing and optionally building the simplest MVP or prototype that validates their current hypotheses. Use when the founder wants to build something to test assumptions, discusses what to build next, wants to interpret results from a live MVP, or is deciding whether the current approach is still right. Also use when a founder proposes something to build — the skill will check whether the proposed form is the simplest thing that generates honest signal.TestingNo warnings★ 3.7K↓ —
- ugc-ad-remixdavepoon/buildwithclaudeTurn a proven UGC video ad into a shot-by-shot script for your own product. Use when the user shares a TikTok, Reels or Shorts ad (link or transcript) and wants a version for their product, asks to "remix", "rewrite" or "copy the structure of" an ad, or needs a UGC script that is ready to film. Uses the free UGCfy AI MCP when it is connected; works from pasted ad text without it.MarketingNo warnings★ 3.7K↓ —

- hey-researchNewdavepoon/buildwithclaudeResearches Robinhood Chain (chain id 4663) projects and tokens with HEY Research Lab's public, source-backed record. Use when someone asks about a Robinhood Chain project, token, $TICKER or 0x contract: is it still being built, what did it ship and when, what changed this week, which project a contract belongs to, or what HEY does not know. Read-only, no key. Not price predictions, trading advice or safety verdicts.ScienceNo warnings★ 3.7K↓ —
- golang-data-structuressamber/cc-skills-golangGolang data structures — slices (internals, capacity growth, preallocation, slices package), maps (internals, hash buckets, maps package), arrays, container/list/heap/ring, strings.Builder vs bytes.Buffer, generic collections, pointers (unsafe.Pointer, weak.Pointer), and copy semantics. Use when choosing or optimizing Go data structures, implementing generic containers, using container/ packages, unsafe or weak pointers, or questioning slice/map internals. Not for applying optimization patterns once profiling has identified a bottleneck (→ See `samber/cc-skills-golang@golang-performance` skill).MarketingNo warnings★ 3.7K↓ —
- golang-concurrencysamber/cc-skills-golangGolang concurrency design — goroutine lifecycle and leak prevention, channels and `select`, channel ownership and direction, `sync.Mutex`/`RWMutex`/`sync.Map`/`sync.Once`/atomics, `errgroup`, `singleflight`, worker pools, and fan-out/fan-in pipelines. Use when writing or reviewing concurrent Go code, when choosing between channels and mutexes, when protecting a shared map or counter, or when a goroutine has no clear exit. Not for defensive coding unrelated to concurrency such as nil panics, slice aliasing, or numeric overflow (→ See `samber/cc-skills-golang@golang-safety` skill), and not for debugging a specific hung, crashing, or racing program after the fact (→ See `samber/cc-skills-golang@golang-troubleshooting` skill).DesignNo warnings★ 3.7K↓ —
- golang-dependency-injectionsamber/cc-skills-golangComprehensive guide for dependency injection (DI) in Golang. Covers why DI matters (testability, loose coupling, separation of concerns, lifecycle management), manual constructor injection, and DI library comparison (google/wire, uber-go/dig, uber-go/fx, samber/do). Use this skill when designing service architecture, setting up dependency injection, refactoring tightly coupled code, managing singletons or service factories, or when the user asks about inversion of control, service containers, or wiring dependencies in Go. For a specific DI library, → See `samber/cc-skills-golang@golang-google-wire`, `samber/cc-skills-golang@golang-uber-dig`, `samber/cc-skills-golang@golang-uber-fx`, or `samber/cc-skills-golang@golang-samber-do` skills.PlanningNo warnings★ 3.7K↓ —
- implement-patchtrailofbits/skillsUse when a confirmed local bug needs an invariant-level fix, variant search, tests, and one local commit.TestingNo warnings★ 7.9K↓ —
- whymichael-denyer/pstack-claudeUse for 'why does X work this way', 'why we picked Y', design rationale, regressions, postmortems, or data-backed thresholds. Discovers available MCPs and queries each evidence category (source control, issue tracker, long-form docs, real-time chat, infrastructure observability, error tracking, product analytics warehouse) in parallel, then returns a cited read on decisions and tradeoffs. Use how for runtime behavior.DevOpsNo warnings★ 3.6K↓ —
- closing-costsdavepoon/buildwithclaudeCalculates itemized state-specific closing costs for mortgage refinance transactions across 10 licensed states, with product-specific fees for Conventional, FHA, FHA Streamline, VA IRRRL, and VA Cash-Out.PlanningNo warnings★ 3.7K↓ —
- reproduce-bugtrailofbits/skillsUse when a named runtime or compiler bug in a local repository needs independent reproduction.OtherNo warnings★ 7.9K↓ —
- patching-bugstrailofbits/skillsUse when a known bug or falsifiable bug hypothesis in a local codebase needs a patch commit and reviewable proof report.EngineeringNo warnings★ 7.9K↓ —
- pr-gardeningpaperclipai/paperclipDiscover the pull requests this Paperclip instance opened (never community contributions), report what each is for and how confident we are that it is merge-ready, and automatically drive the non-ready ones back to green with /prepare-paperclip-pr — without ever merging.OtherNo warnings★ 108.5K↓ —
- report-regressionstrailofbits/skillsUse when assembling or refreshing an evidence-linked regression report from saved campaign decisions.MarketingNo warnings★ 7.9K↓ —
- ops-speedupdavepoon/buildwithclaudeCross-platform, hardware-adaptive system optimizer. Auto-detects macOS / Linux / WSL / Windows (MINGW/Cygwin/MSYS2) and CPU/RAM/disk/GPU profile, then picks the right cleanup strategy. Scans reclaimable disk space, memory pressure, runaway processes, startup bloat, network issues. CleanMyMac built into Claude Code.EngineeringNo warnings★ 3.7K↓ —
- prove-patchtrailofbits/skillsUse when a local security patch commit needs independent scoped and three-arm proof.SecurityNo warnings★ 7.9K↓ —
- dwarf-experttrailofbits/skillsAnalyzes DWARF debug information in compiled binaries. Use when inspecting .debug_* sections, DIE trees, or DW_TAG_/DW_AT_ entries with dwarfdump/llvm-dwarfdump or readelf, verifying debug info with llvm-dwarfdump --verify, answering DWARF standard questions, or writing code that parses DWARF (libdwarf, pyelftools, gimli).WritingNo warnings★ 7.9K↓ —

TestingUpdated Oct 15, 2026
From the author
Direct-invocation specialist for low-fidelity, self-contained HTML wireframes that test information hierarchy, content, navigation, task flow, and responsive structure before visual design. Use when the user explicitly invokes html-wireframe or the broad html skill routes a wireframe request here. Do not activate independently from a general request. Do not use for polished mockups or production-like interaction; use html-prototype for those.
