Influence And Negotiationsamber/cc-skillsInfluence and negotiation toolkit for any interaction needing another person's agreement, even when the user never says 'negotiation'. Covers B2B sales, salary reviews and raise asks, collective bargaining and unions, hard 1:1s, recruitment closes, cross-cultural deals, mediation, and diplomatic messages — declining, pushing back on scope, justifying a delay, raising a concern, getting alignment. Use when the user says 'they just said X, what do I say' or 'draft a reply', or mentions a buyer, champion, procurement, RFP, sponsor, HR, union, or candidate, or a pushback, refusal, ghosting, no-decision, escalation, fixed budget, counter-offer, comp band, strike, BATNA, anchor, or concession.013Linkedin Ghostwritingsamber/cc-skillsB2B LinkedIn ghostwriting — hooks, post structures, and copywriting frameworks for conversion-focused posts. Use when the user wants to write LinkedIn content, create ghostwritten posts, ghostwrite for a founder or executive, or develop a B2B social strategy. Apply when the user shares a story, result, or insight and wants it turned into a post. Do NOT use for newsletter or Substack issues — use samber/cc-skills@substack-ghostwriting instead.04Press Release Writersamber/cc-skillsWrite professional press releases for any occasion, media type, and region. Use when the user wants to write, draft, or improve a press release, communiqué de presse, media announcement, or news release — including product launches, funding rounds, partnerships, crisis communications, executive hires, events, M&A, and open source milestones. Covers media targets (print, digital/wire, broadcast, social/SMPR, trade press) and region-specific conventions worldwide. Also trigger on 'I need to announce something' or 'how do I tell the press about X'. Do NOT use for blog posts or technical articles — use samber/cc-skills@technical-article-writer instead; for newsletter issues, use samber/cc-skills@substack-ghostwriting.08Promql CLIsamber/cc-skillsCLI for querying Prometheus and PromQL-compatible engines (Thanos, Cortex, VictoriaMetrics, Grafana Mimir, Grafana Tempo...) — instant queries, range queries, metric discovery (metrics/labels/meta subcommands), output formats (table/csv/json/graph). Apply when executing PromQL queries, troubleshooting performance issues on a software having observability, investigating latency/error rates/saturation, or analyzing time series data.07Site Launch Checklistsamber/cc-skillsPre-launch checklist for shipping a new website or web app. Scope: analytics (GA4, PostHog, Google Search Console, Ahrefs), DNS, TLS and backups, legal and CNIL/GDPR compliance, security headers, SEO and GEO (robots.txt, sitemaps, llms.txt, hreflang, schema markup, keyword research), copywriting voice via TONE.md and a humanizer pass, OpenGraph and social previews, favicons and web manifest, Lighthouse, Core Web Vitals and WCAG quality gates, directory submissions, Product Hunt, G2/Capterra reviews, post-launch monitoring. Use when the user says 'checklist for the site', 'ready to ship', 'before I go live', 'ready for prod', 'audit before launch', or asks for a site review, pre-launch audit, or help launching a site or app, deploying a domain to production, or shipping a marketing, docs, SaaS, or lead-magnet site.015Skill Progressive Disclosure Designsamber/cc-skillsDecide how to split skill content between SKILL.md and reference files for context efficiency and reliable triggering. Use this whenever creating a new Claude skill, refactoring an existing one, or when a SKILL.md is growing past 300-400 lines. Also trigger when the user mentions "progressive disclosure", "reference files", "splitting skills", "skill bundling", "context window for skills", "SKILL.md too long", "what goes in references/", "skill structure", or expresses any uncertainty about where to put content within a skill. Use this even if the user phrases the question as a triggering problem ("how do I make my skill trigger better"), because that question is often confused with the splitting question and needs to be disentangled first.02Snyk Agent Scan Compliancesamber/cc-skillsCompliance expert for snyk-agent-scan — the agent skill file scanner — NOT for other Snyk CLI tools (snyk test, snyk code SAST, snyk iac, snyk container). Fixes alerts through content restructuring, never by suppressing or deleting information. Covers every file in a skill directory: SKILL.md, references/, assets/, and any secondary markdown. Apply when authoring a new skill, editing an existing one, triaging a failed snyk-agent-scan run locally or in CI, or unblocking a PR held by agent scanner failures. Not applicable to dependency vulnerabilities, code security findings, or infrastructure misconfigurations — those are out of scope.05Substack Ghostwritingsamber/cc-skillsWrite, optimize, and grow Substack content — newsletter issues (email-first) and web posts (web-first essays). Covers voice matching, Substack algorithm and Notes strategy, email formatting, SEO, growth tactics, and paid-subscriber monetization. Use when the user mentions Substack, a newsletter issue, a Substack post or article, evergreen content, newsletter growth, Notes, paid subscribers, 'ghostwrite for', or 'write in the style of' — and for newsletter or essay writing even when Substack is not named, or when adapting a blog post, talk, or thread into newsletter format. Do NOT use for generic blog post writing without a newsletter context — use samber/cc-skills@technical-article-writer instead.08Technical Article Writersamber/cc-skillsWrite technical articles and blog posts for developer audiences — tutorials, explainers, benchmarks, bug hunts, postmortems, and 'we rewrote it in X' posts — with title variants and developer-grade article structure. Use whenever the user asks to write a blog post, technical article, dev.to or Medium post, or any long-form technical content, including 'write about [technical topic]', 'turn this into a blog post', or 'I want to publish something about X', even without naming a format. Do NOT use for newsletter or Substack issues — use samber/cc-skills@substack-ghostwriting instead. Do NOT use for codifying an author's voice — use samber/cc-skills@copywriting-prose-creator instead.04Training Reportsamber/cc-skillsProduce a professional training/workshop report as a .docx file. Use this skill whenever the user mentions "training report", "workshop report", "compte rendu", "compte rendu de formation", "formation report", "debriefing a workshop", "write up a training session", "résumé de formation", or any request to document a training session, workshop, or onboarding event with individual participant feedback and recommendations. Also trigger when the user says things like "I just ran a workshop and need to write it up", "help me summarize what happened in my training session", or "I need to report back to management about a session I ran". Always use this skill — for short or long sessions, across any discipline (technical, soft skills, creative, compliance, onboarding, etc.) — whenever a structured written deliverable about a training event is needed.05
