- pitch-vs-teachmohitagw15856/pm-claude-skillsKnow which talk you're giving — the pitch (drive one decision) vs. the teach (build understanding) — because mixing their structures fails both, and most bad presentations are one wearing the other's clothes. Use when asked is this a pitch or a training, my informative deck didn't land the ask, my pitch felt like a lecture, or structure this talk for the right job. Produces the mode diagnosis, the structural implications, the mixed-mandate split, and the mode-check on an existing deck.DocumentsNo warnings★ 1.5K↓ —
- howNewhashgraph-online/awesome-codex-pluginsExplain how a part of the codebase works, from trigger to result, at the depth an experienced engineer needs to start changing it. Use for "how does X work", "walk me through Y", "where should this code go", "which layer owns Z".EngineeringNo warnings★ 1.5K↓ —
- pentest-reportmohitagw15856/pm-claude-skillsWrite a clear penetration-test report from findings of an authorized engagement.

- skill-creation-walkthroughrampstackco/claude-skillsStep-by-step guide for creating your own Claude Skills, from deciding whether a skill is the right tool to writing the SKILL.md file, structuring reference material, and making it trigger reliably. Use when you want to package a workflow, framework, or repeated task into a reusable Skill, when an existing skill is not triggering or not loading the right context, when you are auditing a skill that is underperforming, or when you want to publish a skill for others. Also triggers when someone asks "how do I make a skill" or "what makes a good skill". Useful for individuals, teams, and anyone publishing skills publicly.WritingNo warnings★ 1K↓ —
- performance-optimizationrampstackco/claude-skillsDiagnose and fix web performance issues including Core Web Vitals (LCP, INP, CLS), bundle size, asset optimization, render performance, and runtime efficiency. Use this skill whenever the user wants to improve page speed, fix Core Web Vitals, optimize assets, reduce bundle size, debug slow renders, or systematically improve a site's performance. Triggers on performance, page speed, Core Web Vitals, LCP, INP, CLS, FID, TTFB, bundle size, code splitting, image optimization, lazy loading, render blocking, slow page, performance audit, Lighthouse score. Also triggers when traffic or conversion is dropping due to perceived slowness.MediaNo warnings★ 1K↓ —
- one-hard-truthmohitagw15856/pm-claude-skillsGet the single honest thing you're avoiding about a situation — said kindly but not softened away. Use when asked tell me the hard truth, what am I avoiding here, be honest with me about this, or what do I not want to hear. Produces the one thing you already half-know but keep sidestepping, said plainly and with care (not cruelty), why it's hard to face, and what facing it would actually make possible — because the truth you're avoiding is usually the one that would change things, and a kind voice can say what your own keeps ducking.OtherNo warnings★ 1.5K↓ —
- ndss-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an NDSS submission calendar — choosing between the summer and fall cycles, backward-planning from the AoE deadline through early-reject, rebuttal, notification, camera-ready, and the Seoul symposium, and placing NDSS honestly inside the security big-four retargeting year.ProductivityNo warnings★ 1.4K↓ —
- hook-failure-audithoangsonww/Claude-Code-Agent-MonitorAudit hook delivery health from Agent Monitor data — balance PreToolUse vs PostToolUse (a gap means tools that started but never reported back), detect missing Stop/SubagentStop terminators (sessions/subagents that never closed), and check for stale ingestion (no recent events). Use when hooks look unreliable or events seem to be dropping.OtherNo warnings★ 1.1K↓ —
- releasehyhmrright/brooks-lintCut a brooks-lint release: set the version in package.json, propagate it across all four plugin manifests and every version-bearing text file (README badges, docs site metadata), write the CHANGELOG entry, validate, then commit, push, tag, and publish the GitHub release. Triggers when the maintainer asks to "release", "cut a release", "ship a new version", or "bump and publish" brooks-lint. Do NOT trigger for: propagating an already-decided version without releasing (use `npm run bump` directly), CHANGELOG edits alone, or questions about the release process that don't ask to perform it.WritingNo warnings★ 1.6K↓ —
- daily-standuphoangsonww/Claude-Code-Agent-MonitorGenerate a daily standup summary from recent Claude Code sessions — completed work grouped by project (cwd), session costs from the pricing engine, tool invocations, error/compaction/APIError events, and turn velocity metrics from session metadata (turn_count, total_turn_duration_ms).EngineeringNo warnings★ 1.1K↓ —
- inithashgraph-online/awesome-codex-pluginsFirst-time Archcore setup. Wires the host (MCP config, hooks, CLAUDE.md/AGENTS.md managed block), measures the authored context the repo already holds, then composes a first-day seed — stack rule, run guide, data-model, integrations, config, entry points, public surface, a linked architecture overview, and specs for the top hotspot modules — shown in ONE preview and created on a single confirm. Modes, named as the first word: init import converts the repo's authored context — CLAUDE.md, AGENTS.md, .cursor/rules and other agent instructions, ADR and RFC folders, contributor docs, internal pages of a published docs site, recoverable git history — into native typed documents with no import marks, staged by a plan when the volume is large; init refresh adds facts that appeared since, or drills into one domain with init refresh <domain>. Use on a fresh clone, empty `.archcore/`, 'set up archcore', 'migrate our CLAUDE.md to archcore', 'import our docs and ADRs', or to wire host configs. Not for individual docs or pPlanningNo warnings★ 1.5K↓ —

- oncall-handoffmohitagw15856/pm-claude-skillsWrite a structured end-of-shift on-call handoff so the incoming engineer inherits state, not surprises. Use when asked to write an on-call handoff, oncall handover, shift handoff, pager handoff, or end-of-week SRE summary. Produces a handoff note with open incidents, watchlist alerts, in-flight investigations, recent changes, and one-line asks.FinanceNo warnings★ 1.5K↓ —
- seo-backlink-auditrampstackco/claude-skillsAudit a backlink profile using Ahrefs MCP data: profile health, anchor text distribution, toxic link identification, lost link reclamation, and gap analysis against competitors. Use this skill when reviewing backlink health, scoping a disavow project, recovering from a manual action, planning link building, or doing M&A due diligence on a property's link equity. Triggers on backlink audit, link profile, toxic links, disavow, anchor text analysis, lost links, link reclamation, referring domains, link gap. Also triggers when traffic decline correlates with link loss or when an unnatural link warning appears in Search Console.MarketingNo warnings★ 1K↓ —
- flight-trackermohitagw15856/pm-claude-skillsTrack live aircraft positions with zero API keys — adsb.lol's open ADS-B network primary, OpenSky fallback, via curl: by callsign, registration, or area.

- explain-simplymohitagw15856/pm-claude-skillsExplain anything in plain language — a contract clause, a medical term, a tax rule, a tech acronym, a news story — layered from a one-liner to as much depth as you want. Use when asked to explain like I'm 5, explain this simply, break this down in plain English, or what does this even mean. Produces the one-sentence version, a plain-language explanation with a concrete analogy, the 'why it matters to you,' and an honest note on anything genuinely uncertain or oversimplified.ScienceNo warnings★ 1.5K↓ —

- ai-tool-pickermohitagw15856/pm-claude-skillsFigure out which AI tool actually fits the task in front of you — chatbot, coding assistant, image model, agent, or none — instead of forcing one tool onto everything. Use when asked which AI tool should I use for, what's the best AI for, do I even need AI for this, or should I use ChatGPT or something else. Produces a match between your task and the right kind of AI tool (with why), the trade-offs that matter for your case, when the answer is a non-AI tool or plain human effort, and how to try it cheaply before committing — so you pick by fit, not by hype or habit.MediaNo warnings★ 1.5K↓ —
