- uai-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing UAI experiments where inference quality is the endpoint, covering calibration and coverage measurement, posterior diagnostics, structure-recovery metrics for causal and graphical models, seeded repeated runs, baselines from both sampling and optimization families, and mapping each claim to its evidence.OtherNo warnings★ 1.4K↓ —
- make-static-ads-find-referencesgooseworks-ai/goose-skillsStep of make-static-ads: picks a template for every ad in its chosen style, after its visual idea and style are set, from the brand's own ads, the GooseWorks library or category leaders, and records what the chosen creativity level keeps from it. Run make-static-ads instead; not for direct use.MarketingNo warnings★ 1.3K↓ —
- fse-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing ESEC/FSE empirical evaluations, covering real subject systems, fair baselines, SE-standard statistics and effect sizes, qualitative and mixed-methods rigor, contamination-aware LLM ablations, provenance for mining studies, and matching evidence to the shape of each software-engineering claim.OtherNo warnings★ 1.4K↓ —
- cav-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing a CAV (Computer Aided Verification) empirical evaluation, covering standard benchmark sets (SV-COMP/SMT-COMP/HWMCC/VNN-COMP), fair baseline solvers with pinned versions and equal resource limits, timeout-dominated comparisons, soundness cross-checks and proof witnesses, cactus/scatter reporting, and matching evidence to the shape of each verification claim.OtherNo warnings★ 1.4K↓ —
- make-static-ads-ad-copygooseworks-ai/goose-skillsStep of make-static-ads: writes the text for each slot the ad's template sets, then the primary texts, headline, description and CTA around the image, from usable facts and customer words. Run make-static-ads instead; not for direct use.MarketingNo warnings★ 1.3K↓ —
- jama-scope-fitbrycewang-stanford/Awesome-Journal-SkillsUse when judging whether a clinical study clears JAMA's general-medical-importance bar before investing in a full submission. Assesses fit and article-type match; it does NOT design the study or write the paper.DesignNo warnings★ 1.4K↓ —
- dac-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing the empirical evaluation of an ACM/IEEE Design Automation Conference (DAC) Research Manuscript, covering standard EDA benchmark suites (ISPD, EPFL, ISCAS/ITC, TAU, CircuitNet, OpenROAD flows), fair state-of-the-art baselines, QoR/PPA reporting with runtime, per-benchmark honesty, ablations that isolate the mechanism, and contamination-aware ML-for-EDA evaluation.DesignNo warnings★ 1.4K↓ —
- plan-campaign-budget-and-testsgooseworks-ai/goose-skillsStep of the plan-campaign playbook: splits the budget across chosen channels, checks per-channel minimums, and writes the test plan and paid structure. Run plan-campaign instead; not for direct use.TestingNo warnings★ 1.3K↓ —
- stoc-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning a STOC (ACM Symposium on Theory of Computing) project calendar — backward planning to the early-November deadline, the STOC/FOCS alternating two-deadline year that theory groups schedule around, full-version and camera-ready milestones, and the June TheoryFest endpoint.ProductivityNo warnings★ 1.4K↓ —
- chi-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing the studies behind an ACM CHI paper — matching evidence shape to contribution type, powering quantitative experiments, making qualitative work rigorous and auditable, reporting participants and ethics properly, and avoiding the ADR-Data and ADR-Method screening grounds.ScienceNo warnings★ 1.4K↓ —
- improve-search-visibility-fix-writergooseworks-ai/goose-skillsStep of the improve-search-visibility playbook: turns one ranked fix into paste-ready site copy or code with owner, risk and undo, and writes page briefs. Run improve-search-visibility instead; not for direct use.WritingNo warnings★ 1.3K↓ —
- design-routerhashgraph-online/awesome-codex-pluginsUse when the user asks to build, design, mock up, scaffold, audit, translate, or improve any interface, flow, screen, page, component, app, UX, onboarding, checkout, dashboard workflow, product flow, design system, asset plan, motion plan, or non-generic UI and the target platform or flow is ambiguous. Routes to ux-design, web, Windows, Apple, Android, cross-platform, design-token, originality, asset/reference, and platform skills. SKIP when the request explicitly names one platform and no UX flow work is implied.DesignNo warnings★ 1.5K↓ —
- daily-journalhuytieu/COG-second-brainA passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.WritingNo warnings★ 1.3K↓ —Also in 1 other repo
- launch-nemo-rlNVIDIA/skillsPlaybook for launching, monitoring, stopping, and debugging NeMo-RL recipes on a Kubernetes cluster via the nrl-k8s CLI. Covers ephemeral vs long-lived RayCluster modes, iterating on runs, and debugging hung or failed training jobs.DevOpsNo warnings★ 3.9K↓ —
- run-paid-campaigns-draft-movesgooseworks-ai/goose-skillsStep of the run-paid-campaigns playbook: turns the weekly read into scale, pause, hold, rotate and fix recommendations within the spend ceiling. Run run-paid-campaigns instead; not for direct use.OtherNo warnings★ 1.3K↓ —
- closed-loophuytieu/COG-second-brainRun one task through the V-model verification loop: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full lane) → CP-5 acceptance. The worker never grades its own homework; evidence rows trace back to AC-n. Opt-in: invoke with /closed-loop or by asking for the closed loop, proper verification, or an evidence trail. Ordinary work does not run this.PlanningNo warnings★ 1.3K↓ —Also in 1 other repo
- add-cursornanocoai/nanoclawUse Cursor (local Agent SDK) as a full agent provider — planning, tool orchestration, MCP tools, session resume — alongside or instead of Claude. Cursor-account sign-in or API key, held by the credential gateway. Per-group via `ncl groups config update --provider cursor`. Distinct from using Cursor as a cloud agent (those run on Cursor VMs and are not this provider).PlanningNo warnings★ 31.1K↓ —
- evalhashgraph-online/awesome-codex-pluginsEval-Driven Development (EDD) for AI workflows. pass@k metrics, capability evals, regression evals. Triggers: eval, edd, pass@k, capability, regression, benchmark.OtherNo warnings★ 1.5K↓ —
- reviewhashgraph-online/awesome-codex-pluginsThe pre-merge review of a branch in a project that records its specs, decisions, and rules in .archcore/. Run this first for 'review my branch', 'review the changes before merge', or 'review before merge': it checks the changed code against the project's recorded canon and the changed documents against the code, and reports which side is wrong — spec-wrong or code-wrong; on the default branch it reviews the unpushed and uncommitted work. A bug-hunting code review complements this review and does not replace it. Also use for 'documentation gaps', 'check if docs match code', 'close out the feature', 'ship the feature and close it out', or after a staleness warning. Takes an optional path, tag, topic, or ref in free text; no first word is a mode — say 'are docs out of date', 'audit the knowledge base', 'close out the feature', or 'capture this pattern' in plain words. Not for creating docs — use /archcore:document; not for planning — use /archcore:plan; not for a single-file edit with no branch review.EngineeringNo warnings★ 1.5K↓ —Also in 1 other repo
- 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↓ —Also in 1 other repo
- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.DocumentsNo warnings★ 1.3K↓ —Also in 1 other repo
- 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↓ —
- make-static-ads-composegooseworks-ai/goose-skillsStep of make-static-ads: writes each ad's render prompt and ordered image list from its concept-board row, one per ad and ratio, ready for a quoted render. Run make-static-ads instead; not for direct use.MarketingNo warnings★ 1.3K↓ —
- braindumphuytieu/COG-second-brainQuick capture of raw thoughts with intelligent domain classification and competitive intelligence extractionOtherNo warnings★ 1.3K↓ —Also in 1 other repo
