- running-github-actions-efficientlykajisho5/ffmpeg-skillCut GitHub Actions minutes and wall-clock time without losing coverage — the OS billing multiplier (macOS 10x / Windows 2x / Linux 1x), trigger hygiene that stops push+pull_request double-firing, concurrency that cancels superseded runs, dependency caching keyed on lockfiles, matrix discipline, and auditing scheduled crons that bill 24/7. Use when CI is burning included minutes, when runs feel slow, when setting up a new repo's workflows, or when reviewing an existing workflow for waste.DevOpsNo warnings★ 4.3K↓ —
- write-outreachgooseworks-ai/goose-skillsCold outreach a person sends to business buyers: email and LinkedIn sequences, a first line per prospect, reply and objection answers, and a read of replies. Use when the marketer says "write a cold email sequence", "what do I send to this list", "write LinkedIn messages for these leads", "how do I reply to this prospect" or "handle this objection", "reply to this demo request", "win back or reconnect with accounts that churned or went quiet", or "why is nobody replying to my outreach". Drafts only; the marketer sends from their own tool. Not for finding the people — use research-audience; not for emails to subscribers or users, or consumer win-back — use email-lifecycle.WritingNo warnings★ 1.3K↓ —
- generate-release-noteshuytieu/COG-second-brainGenerate categorized release notes from any source (GitHub, Linear, Jira, or manual input) with optional publishingProductivityNo warnings★ 1.3K↓ —
- email-lifecycle-flow-writergooseworks-ai/goose-skillsStep of the email-lifecycle playbook: writes one lifecycle flow as a build sheet for the brand's email tool, every message finished in the brand voice. Run email-lifecycle instead; not for direct use.WritingNo warnings★ 1.3K↓ —

- offer-lettermohitagw15856/pm-claude-skillsDraft a job offer — the written offer letter and a verbal-offer script. Use when asked to write an offer letter, a job offer, an employment offer, or to prepare to extend/verbal an offer to a candidate. Produces a clear, warm offer letter (role, comp, start, key terms, contingencies, acceptance) plus a verbal-offer call script — flagging that employment terms need HR/legal review. Not legal advice.LegalNo warnings★ 1.5K↓ —
- fedrampSushegaad/Claude-Skills-Governance-Risk-and-ComplianceExpert guidance for FedRAMP certification and compliance under CR26 (FedRAMP Consolidated Rules for 2026). Use this skill whenever a user asks about FedRAMP authorization, ATO (Authority to Operate), cloud security for federal government, NIST SP 800-53 controls, CSP compliance, or any of the core FedRAMP document types: SSP, SAP, SAR, POA&M, CIS/CRM workbooks. Also trigger for questions about FedRAMP Certification Classes (A, B, C, D — new baseline labels: A = pilot/transitional, B = LI-SaaS/Low, C = Moderate, D = High, per NTC-0004), FedRAMP 20x (now the primary authorization pathway), OSCAL mandate (September 2026), 3PAO assessments, continuous monitoring (ConMon), gap assessments, system boundary definition, or architecture reviews for federal cloud. FedRAMP Ready retired July 28, 2026 (Legacy FedRAMP Ready). When in doubt, use this skill — it covers the full FedRAMP lifecycle from readiness through continuous monitoring.SecurityNo warnings★ 1K↓ —
- dac-workflowbrycewang-stanford/Awesome-Journal-SkillsUse to plan a full ACM/IEEE Design Automation Conference (DAC) Research-Manuscript campaign backward from the mid-to-late-November manuscript deadline through the two-stage abstract-then-manuscript submission on Softconf, the winter review, the March notification, the April camera-ready and copyright for the ACM Digital Library, and the July conference in Long Beach — with the Engineering-Track and Late-Breaking-Results side calendars.ProductivityNo warnings★ 1.4K↓ —
- legacy-lettermohitagw15856/pm-claude-skillsWrite a letter to the people you love, to be read later — the things you'd want them to know, the stories only you hold, the permission and the love that outlive you. Use when someone says 'help me write a letter to my kids/partner', 'legacy letter', 'ethical will', 'something for them to have when I'm gone', or is facing illness, aging, deployment, or simply wants to. Produces a warm, true letter in the writer's own voice — one to each person, or one to all — plus a light plan for when and how it's found. An emotional-legacy tool, not legal (it is not a will).DevOpsNo warnings★ 1.5K↓ —
- iso27701Sushegaad/Claude-Skills-Governance-Risk-and-ComplianceExpert ISO 27701 Privacy Information Management System (PIMS) compliance advisor. Use this skill whenever a user asks about ISO/IEC 27701:2025, ISO/IEC 27701:2019, privacy information management, PIMS certification, PII controller or processor obligations, privacy risk assessment, Statement of Applicability for privacy, privacy by design, data subject rights, DPIA, records of processing activities, transitioning from ISO 27701:2019, GDPR alignment with ISO 27701, or any privacy management system topic. Also trigger for questions about Annex A.1 (controller controls), A.2 (processor controls), A.3 (shared security controls), or implementing a standalone PIMS without ISO 27001. When in doubt, use this skill — it covers the full ISO 27701 lifecycle from gap assessment through certification.SecurityNo warnings★ 1K↓ —
- churn-analysismohitagw15856/pm-claude-skillsProduce a structured churn analysis that separates avoidable from unavoidable churn. Use when investigating why customers are leaving, identifying at-risk segments, calculating net revenue retention, or building a retention intervention plan. Produces a churn report with rate calculations, categorised reasons by avoidability, segment breakdown, timing analysis, early warning signals, and prioritised interventions ranked by estimated impact.FinanceNo warnings★ 1.5K↓ —
- podc-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an ACM PODC campaign end to end — running the single annual cycle backward from the February deadline through abstract registration, lightweight double-blind review, the late-April notification, the May camera-ready, and the arXiv full version — and coordinating the regular-paper-vs-Brief-Announcement decision along the way.ProductivityNo warnings★ 1.4K↓ —
- nsdi-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an NSDI campaign across the spring and fall deadlines — sequencing abstract and paper gates, notification waits, one-shot revision windows, artifact evaluation, and the May symposium — so a networked-systems project always knows which of the two yearly gates it is really building toward.ProductivityNo warnings★ 1.4K↓ —
- cloudflare-email-servicefcakyon/claude-codex-settingsImplement or troubleshoot Cloudflare Email Sending and Email Routing integrations and their delivery configuration.DevOpsNo warnings★ 1.2K↓ —
- building-livekit-agentsfcakyon/claude-codex-settingsBuilds voice and chat AI agents with LiveKit Agents on LiveKit Cloud or a self-hosted server. Use when the user asks to "build a voice agent", "create a LiveKit agent", "add voice AI to my app", "implement handoffs", "structure an agent workflow", "my agent is slow / too chatty", "it says it booked but nothing was saved", "make it confirm before committing", "it keeps re-asking things the caller already said", or is writing code against the LiveKit Agents SDK. Covers architecture: designing for latency, keeping context small, splitting a monolithic agent into handoffs and tasks, and designing for voice. Also covers keeping the model in charge of meaning while code owns state, approvals, and effects. For API specifics use reading-livekit-docs. To check behavior use debugging-livekit-agents and testing-livekit-agents.TestingNo warnings★ 1.2K↓ —
- regulator-eyesmohitagw15856/pm-claude-skillsRead your marketing claims, landing page, or ad copy the way a consumer-protection investigator would (FTC/ASA framing) and draft the inquiry letter they could send. Use when asked to check my marketing claims, read this like a regulator, audit my landing page for claim risk, or is this ad compliant. Produces a claim inventory with substantiation demands, the inquiry letter, and a fix-or-drop debrief per claim.LegalNo warnings★ 1.5K↓ —
- atc-related-workbrycewang-stanford/Awesome-Journal-SkillsUse when writing or auditing the related-work and positioning of an ATC (ACM SIGOPS Annual Technical Conference, formerly USENIX ATC) systems paper — covering the systems literature lanes, positioning against OSDI/SOSP/NSDI/EuroSys/FAST, writing delta-first comparisons, and keeping self-citation double-blind.ScienceNo warnings★ 1.4K↓ —
- icdm-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when auditing an ICDM (IEEE International Conference on Data Mining) submission for readiness, covering Research-vs-Applied track choice and its anonymity regime, the triple-blind sweep, the 10-page IEEE all-inclusive cap, the single June deadline, in-paper artifact references, and the desk-level triggers that get an ICDM paper rejected without review.ScienceNo warnings★ 1.4K↓ —
- fse-related-workbrycewang-stanford/Awesome-Journal-SkillsUse when positioning an ESEC/FSE submission against the software-engineering literature across ICSE, FSE, ASE, ISSTA, MSR, and the SE journals (EMSE, TSE, TOSEM), writing delta-first contrast rather than a citation catalog, keeping self-citations double-anonymous, and handling concurrent, preprint, and prior-version overlap.WritingNo warnings★ 1.4K↓ —
- kdd-camera-readybrycewang-stanford/Awesome-Journal-SkillsUse when preparing an accepted KDD paper for ACM proceedings, covering the 12-page proceedings budget with 9 content pages, the extra content page over the submission, the 3-page cap on references plus appendix, ACM e-rights and TAPS source processing, ACM Open APC status, de-anonymization, and Digital Library metadata for SIGKDD.ScienceNo warnings★ 1.4K↓ —
- ndss-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when performing the final pre-upload audit of an NDSS submission — HotCRP fields, the AoE deadline, NDSS template and 13-page compliance, double-blind sweep, ethics readiness, the six-per-author cap, overlap rules, and desk-reject triage in the last week.LegalNo warnings★ 1.4K↓ —
- sci-abstractbrycewang-stanford/Awesome-Journal-SkillsUse when writing the two front-matter artifacts Science (AAAS) demands — the one-sentence summary for the table of contents and the ≤125-word single-paragraph abstract — both readable by any scientist and both leading with the quantified advance rather than the method. Late-stage polish skill for the flagship AAAS weekly.ScienceNo warnings★ 1.4K↓ —
- podc-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when auditing an ACM PODC submission for HotCRP readiness, covering the two-step abstract-registration then full-paper deadline, the ACM Master template with the 10-page-merits budget and unbounded full version, lightweight double-blind anonymization, the regular-paper-vs-Brief-Announcement choice, and desk-risk triage before the AoE cutoff.ScienceNo warnings★ 1.4K↓ —
