- braindumphuytieu/COG-second-brainQuick capture of raw thoughts with intelligent domain classification and competitive intelligence extractionOtherNo warnings★ 1.3K↓ —Also in 1 other repo
- cmo-advisoralirezarezvani/claude-skillsMarketing leadership: positioning, product-led vs sales-led vs community-led growth, budget split across channels, marketing team design. Use whenever the user asks how to grow, which go-to-market fits or where to spend.DesignNo warnings★ 29.3K↓ —
- replay-user-flowsreticlehq/reticleTurn a user journey you just clicked through into a saved regression check that re-runs deterministically, with no model in the loop and no test code to write. Use when you have driven the same flow twice, when the user wants regression coverage without a Playwright suite, when a refactor needs proving against every existing journey, or when re-verifying by hand is costing a full drive every time.TestingNo warnings★ 1.2K↓ —
- false-green-testsreticlehq/reticleFind out why the tests pass but the app is broken. Catches false greens: a green suite over a feature that does not work, a mocked API standing in for a real one, an assertion that holds no matter what the app does, a click handler wired to nothing. Use when the suite is green and the user says it is broken, when a test never fails, when coverage looks fine but bugs still ship, or before trusting a passing run you did not watch.TestingNo warnings★ 1.2K↓ —
- shiphashgraph-online/awesome-codex-pluginsRelease-gate sequence: validate → review → push → tag. Wraps kernel:git mechanics with the pre-ship safety chain. Triggers: ship, release, push to main, ready to merge, deploy.DevOpsNo warnings★ 1.5K↓ —
- google-apps-scriptjezweb/claude-skillsBuild Google Apps Script automation for Sheets and Workspace. Custom menus, triggers (onEdit / time-driven / form submit), dialogs, sidebars, email batches, PDF export, external API. Use whenever the user wants to automate a Google Sheet, build a Sheets menu / sidebar / dialog, hit a Sheets row from email or a webhook, schedule a Sheets workflow, or asks 'how do I script this in Sheets'.DocumentsNo warnings★ 1.1K↓ —
- relay-80-100-workflowAgentWorkforce/relayUse when writing agent-relay workflows that must fully validate features end-to-end before merging. Covers the 80-to-100 pattern - going beyond "code compiles" to "feature works, tested E2E locally." Includes repair-before-failure validation gates, review-depth fresh-eyes review/fix loops with test hardening, PGlite for in-memory Postgres testing, mock sandbox patterns, test-fix-rerun loops, verify gates after every edit, and the full lifecycle from implementation through passing tests to commit.ProductivityNo warnings★ 1.1K↓ —
- product-ui-tastehuytieu/COG-second-brainAnti-slop skill for PRODUCT UI - dashboards, data tables, forms, multi-step flows, settings, list/detail, app shells. The agent reads the surface, budgets the frame first, and ships dense interfaces that are correct at every edge case (overflow, long labels, empty/error/loading states, i18n expansion, keyboard/a11y). House-system-first; maps to Carbon/Polaris/Atlaskit/Fluent/Primer/Material3/Radix-shadcn/Ant. The counterpart to taste-skill, which owns landing/portfolio/marketing.DesignNo warnings★ 1.3K↓ —
- voice-baselinehuytieu/COG-second-brainMeasure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style. Produces a counted baseline file and checks any new draft against it. Use when an agent's drafts start sounding like a caricature of you, before publishing anything written in your voice, or every ten new pieces to re-measure.WritingNo warnings★ 1.3K↓ —
- eacl-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when auditing an EACL submission before its single ACL Rolling Review cycle deadline, covering ACL-template compliance, the 8-page long / 4-page short content caps, the mandatory Limitations section, the Responsible NLP checklist, anonymization, preprint and resubmission declarations, and the no-fallback-cycle timing trap.LegalNo warnings★ 1.4K↓ —
- weekly-checkinhuytieu/COG-second-brainCross-domain pattern analysis and strategic reflection for weekly reviewEngineeringNo warnings★ 1.3K↓ —
- comprehensive-analysishuytieu/COG-second-brainDeep-dive 7-day analysis across all data sources for weekly reviews, board prep, and strategic planningPlanningNo warnings★ 1.3K↓ —Also in 1 other repo
- responsiveness-checkjezweb/claude-skillsTest website responsiveness across viewport widths using browser automation. Resizes a single session through breakpoints, screenshots each width, and detects layout transitions (column changes, nav switches, overflow). Produces comparison reports showing exactly where layouts break. Trigger with 'responsiveness check', 'check responsive', 'breakpoint test', 'viewport test', 'responsive sweep', 'check breakpoints', or 'test at mobile'.TestingNo warnings★ 1.1K↓ —
- icml-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when stress-testing ICML experimental evidence before submission or rebuttal, including strong tuned baselines, mechanism-isolating ablations, seed variance and confidence intervals, compute disclosure, data leakage and split construction, reproducibility, negative results, and fit to ICML soundness, originality, and significance scoring.TestingNo warnings★ 1.4K↓ —
- release-videohuytieu/COG-second-brainTurn a product release (the list of shipped items plus real screen recordings) into a motion recap video and one explained demo per feature, with sound effects tied to on-screen motion and a composed music bed. Use when asked for a release video, a changelog video, a feature recap reel, or demo clips for release notes and docs.MediaNo warnings★ 1.3K↓ —
- doca-dpdk-bridgeNVIDIA/skillsUse this skill when the user has an existing DPDK application and is adding DOCA capabilities in-place — most commonly DOCA Flow hardware steering — without rewriting the data-plane in DOCA-native form: binding a DPDK port id to a `doca_dev` (`doca_dpdk_port_probe` / `doca_dpdk_port_as_dev`), converting `rte_mbuf` ↔ `doca_buf`, querying `doca_dpdk_cap_is_rep_port_supported`, or debugging `DOCA_ERROR_*` from a bridge call. Trigger even without "DOCA DPDK Bridge": "how do I add DOCA Flow to my DPDK app", "make a DPDK port visible to DOCA", "the bridge loads but every operation returns errors", "pkg-config --exists doca-dpdk-bridge fails", or "DOCA_ERROR_NOT_FOUND on port registration". Route elsewhere for fresh DOCA-native packet I/O (doca-eth), flow-rule programming (doca-flow), DOCA or DPDK install (doca-setup), or RDMA data movement (doca-rdma).PlanningNo warnings★ 3.9K↓ —
- review-prfcakyon/claude-codex-settingsThis skill should be used when user asks to "review a PR", "review pull request", "review this pr", "code review this PR", "check PREngineeringNo warnings★ 1.2K↓ —
- memory-hygienehuytieu/COG-second-brainPeriodic trust sweep of persistent memory and durable knowledge notes - re-verifies environment-dependent claims against the live environment, stamps last_verified + confidence, and proposes archiving drifted entriesProductivityNo warnings★ 1.3K↓ —
- update-knowledge-basehuytieu/COG-second-brainMaintain and update product knowledge base from releases, features, and project changes with optional wiki syncOtherNo warnings★ 1.3K↓ —Also in 1 other repo
- auto-researchhuytieu/COG-second-brainDeep strategic research engine — decomposes questions into parallel research threads, spawns multiple agents, and synthesizes into actionable strategic analysisScienceNo warnings★ 1.3K↓ —
- generate-prdhuytieu/COG-second-brainGenerate product requirements documents with optional publishing to Confluence or other wiki platformsPlanningNo warnings★ 1.3K↓ —
- taste-skillhuytieu/COG-second-brainAnti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.DesignNo warnings★ 1.3K↓ —
- image-processingjezweb/claude-skillsProcess images for web development — resize, crop, trim whitespace, convert formats (PNG/WebP/JPG), optimise file size, generate thumbnails, create OG card images. Uses Pillow (Python) — no ImageMagick needed. Trigger with 'resize image', 'convert to webp', 'trim logo', 'optimise images', 'make thumbnail', 'create OG image', 'crop whitespace', 'process image', or 'image too large'.MediaNo warnings★ 1.1K↓ —
- wordpress-elementorjezweb/claude-skillsEdit Elementor pages and manage templates on WordPress sites via browser automation (for visual / structural changes) or WP-CLI (for safe text replacements). Use whenever the user wants to edit an Elementor page, update text in Elementor widgets, apply or manage Elementor templates, or make content changes to pages built with the Elementor page builder.BrowserNo warnings★ 1.1K↓ —
