Obsidian Markdownkepano/obsidian-skillsCreate and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax. Use when working with .md files in Obsidian, or when the user mentions wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes.4274Playwright Best Practicescurrents-dev/playwright-best-practices-skillUse when writing Playwright tests, fixing flaky tests, debugging failures, implementing Page Object Model, configuring CI/CD, optimizing performance, mocking APIs, handling authentication or OAuth, testing accessibility (axe-core), file uploads/downloads, date/time mocking, WebSockets, geolocation, permissions, multi-tab/popup flows, mobile/responsive layouts, touch gestures, GraphQL, error handling, offline mode, multi-user collaboration, third-party services (payments, email verification), console error monitoring, global setup/teardown, test annotations (skip, fixme, slow), test tags (@smoke, @fast, @critical, filtering with --grep), project dependencies, security testing (XSS, CSRF, auth), performance budgets (Web Vitals, Lighthouse), iframes, component testing, canvas/WebGL, service workers/PWA, test coverage, i18n/localization, Electron apps, or browser extension testing. Covers E2E, component, API, visual, accessibility, security, Electron, and extension testing.42759Oss Launchsamber/developer-relations-skillsPlans and runs an open-source project launch end to end - name and license clearance, the readiness gate, positioning and one-liner, channel sequencing, the launch-day war room, star-velocity and GitHub Trending mechanics, and post-launch measurement. Use whenever someone is about to release, announce, open-source or "Show HN" a repository, asks how to reach GitHub Trending, wants the first real users or stars for a new library, is planning a Product Hunt post or a multi-day launch week, or asks why a launch fell flat (even if they only say they are pushing a repo public). Covers individual-developer and company adoption. Not ongoing distribution afterwards - use samber/developer-relations-skills@oss-distribution-strategy instead.4268AI Video Generationprime-skills/runcomfy-agent-skills>4251Developer Community Launchsamber/developer-relations-skillsDecides whether, where and when to launch a developer community, then plans its seeding and first 90 days - venue selection, founding-member seeding, go/no-go criteria, the cheaper no-community alternatives, and shutdown criteria. Use whenever someone asks whether to start a Discord, Slack or forum for their users, which community platform to pick, how to launch or seed a developer community from zero, or how to reach critical mass - even if they only say "we should have a Discord". Do NOT use for a community that already exists; measurement is samber/developer-relations-skills@developer-community-health and moderation is samber/developer-relations-skills@developer-community-moderation.4255Developer Meetup Programsamber/developer-relations-skillsDesigns and runs a recurring developer meetup or user group - purpose and host model, format menu, cadence, a standing speaker pipeline, in-kind venue and food sponsors with their conduct limits, no-show planning, the attendee-to-co-organizer ladder, and a health scorecard. Use whenever someone mentions starting a developer meetup or user group, dying meetup attendance, finding meetup speakers, getting a venue or pizza sponsor, how often to meet, RSVPs who never show, or handing the meetup over - even if they only say "we want to do local events". Covers independent, vendor-backed and company-staffed groups. Not for speaking at a conference - use samber/developer-relations-skills@conference-cfp-submission.4259Devrel Budget Allocationsamber/developer-relations-skillsSplits a developer relations budget across pillars - events, content, community, tooling, education, OSS sponsorship - into line items that each carry a cash cost, an hours cost, a pre-set return threshold, a review date and a reallocation rule, plus a ranked cut list. Use whenever someone asks how to plan or split a devrel budget, how much to spend on events versus content versus community, whether a line item is worth its money, how to defend a devrel budget at review, or what to cut first when the budget shrinks - even if they only say "we spend too much on conferences". Not the metrics framework (samber/developer-relations-skills@devrel-metrics) or one event's ROI (samber/developer-relations-skills@developer-event-sponsorship).4256Face Swapprime-skills/runcomfy-agent-skills>4251Image To Videoprime-skills/runcomfy-agent-skills>4251Video Editprime-skills/runcomfy-agent-skills>4251Devrel Metricssamber/developer-relations-skillsBuilds a developer relations measurement framework - a handful of metrics tiered from reach to product and business impact, each with a written attribution rule, a baseline-derived target, an owner and an action, and vanity metrics cut. Use whenever someone asks how to measure DevRel, which devrel KPIs matter, how to prove devrel value or ROI to an exec, what belongs in a devrel scorecard or quarterly report, why their numbers look good but leadership stays unconvinced, or reports only stars, impressions and event counts - even if they never say "metrics". Do NOT use for tracking instrumentation and dashboards - use samber/developer-relations-skills@devrel-analytics. Not community-only health metrics, not a single event's ROI.4245Gpt Image 2prime-skills/runcomfy-agent-skills>4241Image Editprime-skills/runcomfy-agent-skills>4241Image Inpaintingprime-skills/runcomfy-agent-skills>4241Runcomfy CLIprime-skills/runcomfy-agent-skills>4241Seedance V2prime-skills/runcomfy-agent-skills>4241AI Avatar Videoprime-skills/runcomfy-agent-skills>4231Developer Quickstart Guidesamber/developer-relations-skillsWrites or audits a developer quickstart that carries a reader from zero to one verified success - minimal path, copy-paste commands, expected output at every step, fail branches, and a cold-run time budget. Use whenever the user mentions a quickstart, a getting-started page, a hello-world doc, "time to first success" or "time to first value", onboarding docs for an API, SDK, CLI or self-hosted tool, or complains nobody finishes their getting-started page - even if they only say "our setup is too hard". Do NOT use for a teaching tutorial (samber/developer-relations-skills@developer-tutorial) or a README rewrite (samber/developer-relations-skills@readme-optimization).4236Devrel Strategysamber/developer-relations-skillsDesigns a company's developer relations program from the top - the business driver that funds it, the two goals it is allowed to serve, the pillar mix (advocacy, marketing, enablement, community) for its stage, audience priority, build-vs-buy per bet, staffing sequence, and a written refused list. Use whenever someone asks whether to start doing DevRel, what a new devrel program should do first, why devrel work is busy but not landing, how to justify the program to an exec, which pillar deserves the next investment, who to hire next, or whether to outsource content, events or community - even if they never say "strategy". Not the first-90-days plan - use samber/developer-relations-skills@developer-relations-kickoff. Not metrics, org chart or budget math.4235Lipsyncprime-skills/runcomfy-agent-skills>4231Nano Banana 2prime-skills/runcomfy-agent-skills>4231Open Source Company Strategysamber/developer-relations-skillsDecides what a company open-sources and what stays proprietary, names the strategic motive for each side of the line, says who owns the decision, and states what the company commits never to close. Use whenever someone asks "should we open source this?", "what should we open source", "where do we draw the open-core line", "which features stay paid", "who signs off on open sourcing this", or wants a company-level open source strategy rather than a plan for one project - even if they frame it as a licensing question. Produces an asset-by-asset open/closed verdict, a value-capture and irreversibility check, a public non-reversal commitment and a re-evaluation trigger. Not license selection - use samber/developer-relations-skills@oss-license-strategy.4237Ace Stepprime-skills/runcomfy-agent-skills>4221AI Musicprime-skills/runcomfy-agent-skills>4221Developer Ecosystem Strategysamber/developer-relations-skillsDecides whether, when and how far a developer product should open into a platform other companies build on - extension points, partner-built integrations, third-party apps, a complement ecosystem - and what that permanently obliges you to. Use whenever someone asks if the product should become a platform, whether to open extension points or an app model to third parties, how to start an integration ecosystem, why nobody builds on the API, whether partners should build the connectors, or how much value complementors must keep - even if they only say "we want an integrations story". Not marketplace operations or API design. Do NOT use for the revenue model - use samber/developer-relations-skills@devtools-business-model.4225Elevenlabs Music Generationprime-skills/runcomfy-agent-skills>4221Gpt Image Editprime-skills/runcomfy-agent-skills>4221Image Outpaintingprime-skills/runcomfy-agent-skills>4221Kling 3 0prime-skills/runcomfy-agent-skills>4221Nano Banana Editprime-skills/runcomfy-agent-skills>4221Relightprime-skills/runcomfy-agent-skills>4221Video Extendprime-skills/runcomfy-agent-skills>4221Codex Petprime-skills/runcomfy-agent-skills>4211Controlnet Poseprime-skills/runcomfy-agent-skills>4211Developer Championssamber/developer-relations-skillsDesigns an unpaid, perks-only developer champions or ambassador program end to end - readiness check, intake model, published selection criteria, behaviour-based obligations, an access-first perk ladder, fixed terms with renewal and alumni status, and a cohort scorecard. Use whenever the user mentions an ambassador or champions program, MVP-style recognition, community heroes, "how do we recognise our top community members", what perks ambassadors should get, an ambassador program that went quiet, or removing an inactive champion - even if they never say "champion". Not for paid creator, affiliate or revenue-share partnerships. For measuring the community itself use samber/developer-relations-skills@developer-community-health.4215Devrel Radarsamber/developer-relations-skillsBuilds a personalised, time-budgeted watch list of developer-relations information sources - DevRel podcasts, newsletters, practice hubs, peer communities, conference calendars, ecosystem data reports and practitioners worth following - plus the routine that keeps it verified and fresh. Use whenever a developer advocate, community manager, DevRel lead or OSS maintainer asks for a DevRel radar, how to stay current on developer relations, which DevRel podcasts, newsletters or Slack communities deserve their time, which developer conferences to attend or speak at, who to follow in DevRel, or to refresh a radar built earlier - even if they only say they feel out of the loop. Not for tracking a rival vendor - use samber/developer-relations-skills@devrel-competitor-analysis.4215Flux 2 Kleinprime-skills/runcomfy-agent-skills>4211Flux Kontextprime-skills/runcomfy-agent-skills>4211Happyhorse 1 0prime-skills/runcomfy-agent-skills>4211Oss Governancesamber/developer-relations-skillsChooses and documents an open-source project's governance model - decision rights, maintainer roles and promotion, voting and consensus rules, conflict escalation, succession, trademark and asset control, and whether to join a foundation or fiscal host. Use whenever someone asks who decides in their project, wants to write or fix a GOVERNANCE.md, is adding or removing maintainers, worries about bus factor or a single-vendor-controlled project, faces a deadlocked or contested decision, or is preparing a foundation donation - even if they only say the project has no rules. Covers solo, company-backed and multi-vendor projects. Not license, CLA or DCO choice - use samber/developer-relations-skills@oss-license-strategy. Never legal advice.4219Video Inpaintingprime-skills/runcomfy-agent-skills>4211Video Outpaintingprime-skills/runcomfy-agent-skills>4211Wan 2 7prime-skills/runcomfy-agent-skills>4211Developer Community Moderationsamber/developer-relations-skillsWrites a developer community's code of conduct and the moderation playbook behind it - scope, enforcement ladder, reporting channels, incident-response runbook, moderator roster, platform controls. Use whenever the user mentions a code of conduct, CODE_OF_CONDUCT.md, community moderation, moderator recruitment, an escalation ladder, banning or suspending a member, harassment, trolls, brigading, spam or AI-slop floods, or a conduct report they need to handle - including vaguer phrasings like "our Discord is getting out of hand", "we need community rules", or "someone reported a maintainer". Covers company-run and volunteer open-source communities. Do NOT use to pick the platform - use samber/developer-relations-skills@developer-community-launch.4206Oss Contributor Onboardingsamber/developer-relations-skillsDesigns and verifies the path a stranger walks to their first merged contribution on an open-source project - the CONTRIBUTING file, the good-first-issue queue, a clone-to-passing-tests command that works cold, and the first-pull-request review and recognition loop, scored against a blocking-plus-weighted rubric. Use whenever someone says "nobody contributes to my project", "write a CONTRIBUTING.md", "our good first issues get no takers", "first-time contributors disappear", "contributor onboarding", "first pull request experience", or "how do we get more open-source contributors" - even if they only complain about a lonely repo. Not triage-system design - use samber/developer-relations-skills@oss-issue-triage. Not governance or CLA choice.4207Oss Sponsors Fundraisingsamber/developer-relations-skillsDesigns a maintainer-side open-source sponsorship program - the tier ladder and its pricing for individual and corporate sponsors, rewards that stay deliverable at ten times the sponsor count, funding-goal and sustainability framing, and the invoice-and-entity path a company needs before it can pay. Use whenever a maintainer asks how to get sponsors or funding for a project, sets up or fixes GitHub Sponsors, Open Collective or FUNDING.yml, writes sponsor tiers, rewards or a sponsorship page, wonders why nobody sponsors a widely used project, considers sponsorware, or wants a company to fund maintenance work - even if they only say the project is unsustainable. Not the company side - use samber/developer-relations-skills@oss-sponsors-brand-strategy.4197Developer Docs Structure Auditsamber/developer-relations-skillsAudits an existing developer documentation set's structure - a page-by-page inventory classified against the Diátaxis modes (tutorial, how-to, reference, explanation), mixed-mode and misplaced pages, coverage gaps per product surface, navigation drift against the file tree, a CNCF TechDocs rubric score, and a prioritized remediation queue. Use whenever the user mentions a docs structure or content audit, docs information architecture, Diátaxis, "our documentation is a mess", a docs gap analysis, what docs are missing, where a page should live, or reorganizing a documentation site - even if they only say "our docs are hard to navigate". Not for writing pages. Do NOT use for docs search ranking - use samber/developer-relations-skills@docs-seo.4189Devrel Content Calendarsamber/developer-relations-skillsPlans a quarter of developer-relations content as a dated slot plan with named owners and reviewers - fixed anchors (releases, launches, CFP deadlines, conferences), a surface, pillar, journey and shelf-life mix, and sizing against real writing and review capacity. Use whenever the user asks for a devrel content calendar, an editorial calendar or content plan for a developer audience, what to publish next quarter, how to balance evergreen against launch-tied content, how many pieces a small team can ship, or says their content plan keeps slipping - even if they only say "we publish randomly". Plans the quarter only; individual pieces go to the per-format skills such as samber/developer-relations-skills@engineering-blog-post.4185
