- feedbackdavepoon/buildwithclaudeTurn post-task feedback—even blunt or angry feedback—into an evidence-based, approval-gated improvement plan for the agent/user workflow.

- red-handed-auditdavepoon/buildwithclaudeCheck whether the tests the agent said passed actually ran. Reads the Claude Code session transcript and git state locally, then reports each gap with a timestamp and the quoted line. No model calls, nothing leaves the machine.TestingNo warnings★ 3.7K↓ —
- flyio-hello-worldjeremylongshore/tons-of-skills-marketplacePrepare and verify a minimal Fly.io application launch with reviewable configuration and a safe first deployment. Use when onboarding a new service. Trigger with: "launch first Fly app", "deploy hello world to Fly", "create Fly launch plan".DevOpsNo warnings★ 2.9K↓ —
- cohere-hello-worldjeremylongshore/tons-of-skills-marketplaceRun bounded Cohere v2 Chat, Embed, or Rerank requests with current model discovery and explicit validation.

- principle-separate-before-serializing-shared-statemichael-denyer/pstack-claudeApply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant.WritingNo warnings★ 3.9K↓ —
- offensive-krack-fragattacksSnailSploit/Claude-RedKRACK (CVE-2017-13077..082) and FragAttacks (CVE-2020-24586..588 + 26139-26147) — key reinstallation, fragmentation, and aggregation attacks against WPA2 supplicants. Covers Vanhoef's test scripts, viability against modern patched stacks (mostly mitigated post-2021), residual unpatched embedded devices and IoT vendors, and the practical limitations of these attacks in modern engagements. Use when assessing legacy supplicants, embedded clients, or vendors with poor patch cadence.SecurityNo warnings★ 10.3K↓ —
- castai-rate-limitsjeremylongshore/tons-of-skills-marketplaceBuild a CAST AI REST client that respects endpoint-specific throttling, bounded retries, and an explicit request budget. Use when a job receives 429 responses, polls CAST AI, or fans out across clusters and organizations. Trigger with: "handle CAST AI rate limits", "stop CAST AI 429s", "make CAST AI polling safe".PlanningNo warnings★ 2.9K↓ —
- daily-focus-boardgithub/awesome-copilotSpin up a personal, motivating daily focus board that renders in a browser canvas and that the user drives by talking to their AI partner. Tasks track status (to-do → in progress → done) with timestamped progress notes and roll up into a "today's momentum" feed; numeric-goal tasks (pages, pomodoros, reps) render as progress-bar counters. Executive-function / neurodivergent-friendly by design: Focus mode, kind "not today" carryover (no overdue-shaming), a brain-dump box, reduced-motion, and gentle deadline countdowns. Add, reorder, and relabel tasks live, assign Eisenhower priority (Do first / Schedule / Delegate / Later), open with an above/below-the-line check-in and a daily mantra, and save an end-of-day recap. Use when someone wants to plan their day, stay focused, kick off a work session, or track progress. Progress persists in the browser (localStorage).DesignNo warnings★ 40.8K↓ —

- landing-page-cro-expertcbrock84/headcountAudits and rewrites landing pages, homepages, and sales pages to increase conversion — diagnosing why a page is not converting, rewriting headlines, hero copy and calls to action, and prioritizing which changes to test first. Use this when a page underperforms, when someone pastes a URL or screenshot asking what is wrong, when writing a new page, or when deciding which conversion changes are worth testing.DesignNo warnings★ 2.6K↓ —
