- cf-proxydavepoon/buildwithclaudeDeploy a free VLESS proxy/VPN node on Cloudflare Pages using edgetunnel. Automates code download, UUID generation, Pages deployment, free domain registration (DNSExit), DNS configuration, custom domain binding, and client setup for Shadowrocket/v2rayN/Clash. Uses Cloudflare Pages (not Workers) because Pages supports CNAME-based custom domains from any DNS provider, avoiding the need to host DNS on Cloudflare.DevOpsNo warnings★ 3.7K↓ —

- gsd:workstreamsdavepoon/buildwithclaudeManage parallel workstreams — list, create, switch, status, progress, complete, and resumeOtherNo warnings★ 3.7K↓ —
- team-reviewNewwesammustafa/Claude-Code-Everything-You-Need-to-KnowThe team's review of a change to linkcheck, run the same way on a laptop and in CI. Use on a staged diff or a pull request.EngineeringNo warnings★ 3.5K↓ —
- htmlplannotator/effective-htmlCreate or redesign self-contained single-file HTML artifacts with a visual direction shaped by the user's brief, project, and subject. Use when HTML is the deliverable for a report, explainer, landing page, presentation, tool, mixed artifact, or broad request. This is the collection's only implicit router. Route clear wireframe, prototype, mockup, plan, or diagram requests to the matching direct-invocation specialist when available. Do not use for ordinary application implementation when a standalone HTML file is not the deliverable.DesignNo warnings★ 3.8K↓ —
- codejeremylongshore/tons-of-skills-marketplaceUse BEFORE generating, refactoring, reviewing, or debugging code. Trigger phrases include "write a function/script/class for X", "review this code/diff/PR", "refactor this", "debug this error", "is this implementation correct", "what's wrong with this code", "improve this code", "translate from X to Y", or any prompt with a code block the user wants you to act on. Also fires when planning architectural changes, picking algorithms or data structures, or evaluating dependency upgrades. Calls the code MCP tool to retrieve an engineering scaffold (failure pattern, procedure, correct-pattern example, verification step) before generating. Catches hallucinated APIs, lost edge cases, premature algorithm commitment, silent contract violations, refactors that change behavior masked by passing tests. Do NOT trigger for pure code reading with no action requested, simple syntax questions, file system operations, running existing tests, or confirming an existing pattern is fine.EngineeringNo warnings★ 2.9K↓ —
- web-analyticsjeremylongshore/tons-of-skills-marketplaceAnalyze Umami or GA4 traffic with evidence-backed specialist reviews and deliver a concise portfolio pulse, decision brief, or deep dive. Use when the user asks to check analytics, explain a traffic change, inspect funnels, compare site performance, or prepare an analytics report. Trigger with "/analytics", "check my analytics", "how's my traffic", "site stats", "traffic report", or "analytics brief".DataNo warnings★ 2.9K↓ —

- html-planplannotator/effective-htmlDirect-invocation specialist for clear, self-contained HTML plans that preserve source material while improving hierarchy, sequence, ownership, dependencies, and reviewability. Use when the user explicitly invokes html-plan or the broad html skill routes a plan request here. Do not activate independently from a general request.PlanningNo warnings★ 3.8K↓ —
- gsd:extract-learningsdavepoon/buildwithclaudeExtract decisions, lessons, patterns, and surprises from completed phase artifactsOtherNo warnings★ 3.7K↓ —
- sharpenmichael-denyer/pstack-claudeMake a task deeper, not bigger, then rewrite the prompt. Use for /sharpen.ProductivityNo warnings★ 3.9K↓ —
- cross-linkerAr9av/obsidian-wikiFind and add missing cross-references between wiki pages. Use when pages are disconnected or after large ingestion. This modifies pages to add links; use wiki-lint for report-oriented structural auditing.OtherNo warnings★ 3.7K↓ —

- risk-analysisjeremylongshore/tons-of-skills-marketplaceAnalyze supplied contract clauses and prepare an evidence-linked issue register with triggers, possible impacts and questions for review. Use when assessing contract risks from an identified party's perspective. Trigger with "risk-analysis" or "what are the risks in this contract".LegalNo warnings★ 2.9K↓ —
- impeccablepbakaus/impeccableUse when the user wants to design, redesign, shape, critique, audit, polish, simplify, harden, animate, or otherwise improve a frontend interface: websites, landing pages, dashboards, product UI, components, forms, settings, onboarding, empty states, and native iOS or Android screens. Handles UX review, hierarchy, layout, typography, color, motion, UX copy, accessibility, responsive behavior, edge cases, and capturing or documenting design systems (DESIGN.md, tokens). Also for making bland UI bolder, loud UI quieter, or ambitious visual effects. Not for backend-only or non-UI tasks.DesignNo warnings★ 101.2K↓ —
- pulumi-cdk-to-pulumipulumi/agent-skillsLoad this skill when a user wants to migrate, convert, port, translate, or move an AWS CDK application (including CDK stacks, constructs, or CloudFormation-synthesized templates) to Pulumi. Phrases such as "convert CDK to Pulumi", "migrate CDK app", "port CDK stacks", "replace CDK with Pulumi", "stop using CDK". Do NOT load for general CDK questions, CDK-only help, or CDK vs Pulumi comparisons where no migration is requested.OfficialDevOpsNo warnings★ 78↓ —
- pulumi-terraform-to-pulumipulumi/agent-skillsMigrate Terraform/OpenTofu projects to Pulumi, including translating HCL source code and/or importing Terraform state into a Pulumi stack. Use when a user wants to convert Terraform to Pulumi, migrate from HCL, or import tfstate into Pulumi.

variant-analysis
trailofbits/skills
SecurityUpdated 22 hours ago
From the author
Hunts for the other instances of a bug already found — the variants of one root cause across a codebase. Use immediately after a vulnerability, logic bug, or bad pattern turns up in a specific file and the question becomes where else it occurs, including the bare conversational form ("are there others like this?", "is this the same bug?"). Also for generalizing one known instance into a CodeQL or Semgrep query for its whole pattern family, and for triaging a set of look-alike candidates against a known root cause. Not for initial discovery with no bug in hand.
