- fixing-flaky-testsamplifthq/openmeldGuides an agent through reproducing, root-causing, fixing, and validating flaky tests in the PostHog monorepo. Use when a test fails intermittently in CI but passes on rerun or locally, when `hogli ci:insights` or the debugging-ci-failures skill classifies a failure as a flaky test, when given a GitHub Actions URL for a flaky job, when asked to check Trunk Flaky Tests for a test, PR, or master, or when asked to deflake, stabilize, or fix a flaky Jest, pytest, or Playwright test. Core discipline: reproduce locally before changing anything, fix the root cause (never mask it with sleeps, retries, or bigger timeouts), and prove the fix with an N-run validation loop sized to the observed failure rate. Stabilizing is not the only valid outcome — the skill also gates whether the test should exist, so deleting a test that catches nothing real, or re-leveling one that flakes because of the level it runs at, are first-class endings.TestingNo warnings★ 1.4K↓ —
- improve-search-visibility-question-setgooseworks-ai/goose-skillsStep of the improve-search-visibility playbook: drafts and scores the buyer-question set in AI and Google forms and groups it into page clusters. Run improve-search-visibility instead; not for direct use.OtherNo warnings★ 1.3K↓ —

- run-paid-campaigns-health-gategooseworks-ai/goose-skillsChecks that ads are safe to spend on: conversion tracking recording, landing pages loading on mobile with the right product, price and offer, enough stock behind promoted products, no disapproved ads, and no account or payment stop. Marks each pass, fail or unknown and turns fails into fixes. Use alone when you already have the live or planned ads and their landing pages; otherwise run run-paid-campaigns.FinanceNo warnings★ 1.3K↓ —
- compare-showshashgraph-online/awesome-codex-pluginsCompares two podcasts or YouTube shows side by side: size, latest episode, what each talks about, what both cover, and shared sponsors. Uses arcmira.OtherNo warnings★ 1.5K↓ —
- make-content-two-pass-editgooseworks-ai/goose-skillsEdits an existing draft in order: a substance pass (arguable thesis, swap test, fakes removed, CTA fit), a claims and fact check that cuts or softens unproven lines, a readability and voice-match pass, then an AI-tell sweep, with an edit note listing open gaps. Use alone when you already have a finished draft and the brand's voice samples and approved claims; otherwise run make-content.WritingNo warnings★ 1.3K↓ —
- render-creator-pip-listiclegooseworks-ai/goose-skillsAssemble a creator picture-in-picture product-listicle ad from a config. The creator stays full-frame for every beat (voice and lips generated together), and each product beat carries three overlays for the whole beat: a title pill, the product demo in a rounded picture-in-picture window (the brand's muted UGC clip, or its UI still or screen recording), and a product card with thumbnail, number, category and name. Hook and CTA beats show the creator with the title pill only. It builds one overlay image per beat, composites it on the creator clip, concatenates the beats and burns timed captions last. Free, deterministic assembly; the creator anchor and talking clips come from create-image-fal and create-video-fal. Use for the creator-pip-listicle format.MediaNo warnings★ 1.3K↓ —
- make-content-content-briefgooseworks-ai/goose-skillsWrites a one-page content brief before any draft: audience, intent, the one arguable point, what top results already say and what this piece adds, an outline, a proof inventory with gaps marked, voice, CTA and banned words, checked against six gates. Use alone when you already have the topic, format, audience and destination and want only the brief; otherwise run make-content.WritingNo warnings★ 1.3K↓ —
- weekly-reviewnano-muse/nanoMusenanoMuse: an open-source personal agent for every device you own. One agent with a name and a look of its own that does things, keeps working while the app is closed, remembers you, and asks before anything you cannot undo. On Android, iPhone and iPad, Windows / macOS / Linux and in the browser; your phone's screen and your computer as its hands.EngineeringNo warnings★ 3.1K↓ —

- subagentevo-hq/evoProtocol that evo optimization subagents follow when dispatched from /optimize. Auto-loaded by spawned subagents via their host's skill loader. The orchestrator may also invoke this skill to understand the brief shape its dispatched subagents expect + what they're required to emit -- useful when writing briefs or debugging a subagent's behavior.WritingNo warnings★ 1.5K↓ —Also in 1 other repo
- which-skillmohitagw15856/pm-claude-skillsRoute a fuzzy request to the right skill in this library. Use when the user is unsure which skill fits, asks 'which skill should I use for X', describes a task without naming a skill, or when a request could plausibly match several skills. Produces a best-fit recommendation with the inputs to gather, a runner-up with the tie-breaker, and a workflow recipe when the job spans multiple skills.ProductivityNo warnings★ 1.5K↓ —
- world-clockmohitagw15856/pm-claude-skillsGet the current time anywhere and convert between time zones with zero API keys — timeapi.io via curl (worldtimeapi fallback), plus the DST-safe meeting-window math.
