- elasticsearch-anomaly-detectionelastic/agent-skillsCreate and manage Elastic ML anomaly detection jobs via the API. Use when setting up jobs on an index or data stream, configuring jobs and datafeeds, or opening, starting, or stopping them.OfficialEngineeringNo warnings★ 602↓ —Also in 1 other repo
- k12-lesson-prepanthropics/k12-teacher-skillsHelps a teacher prepare to teach an existing K-12 lesson (math / ELA / science / social studies) — a prep partner that thinks through the lesson's key student task with the teacher and leaves a short teacher-only prep note. Triggers on asks to internalize, prepare for, get ready to teach, or understand a lesson, including implicit ones ("help me get ready for tomorrow's lesson"), and right after another skill built a lesson, which it can follow. Not for building or adapting a lesson, grading, rubrics, assessment feedback, or generating quizzes or student-facing material, and not for single-fact lookups a sentence would answer ("what standard is this?", "how long is this lesson?").OfficialScienceNo warnings★ 598↓ —
- ui-mockupmvschwarz/openrigCreate UI mockups at three fidelity levels — ASCII wireframes for quick iteration, standalone HTML mockups for delivery with requirements, and live prototypes for interaction testing.DesignNo warnings★ 8.3K↓ —Also in 1 other repo
- exec-summarymvschwarz/openrigGenerate a 1-2 page executive summary for a feature — orients sales, leadership, and engineering from a single document.ProductivityNo warnings★ 8.3K↓ —Also in 1 other repo
- agent-operated-workflowsmvschwarz/openrigUse when a bounded real-world procedure has a deterministic happy path but brownfield, variable, or partially knowable state; when an operation must resume from verified evidence; or when deciding whether agent judgment or ordinary code should own a procedure's control loop.EngineeringNo warnings★ 8.3K↓ —
- openrig-cmuxmvschwarz/openrigUse when opening OpenRig fleet terminals into cmux — turning a rig, pod, mission, slice, or saved view into live agent tiles via `rig terminal --provider cmux`, or driving cmux on an agent's request. Same OpenRig view semantics as openrig-herdr (the verbs, honest-partial/degrade, read-only cross-rig, scroll/copy, same-size-only duplicates); cmux is the **best-effort** provider (herdr is the default and the proof-gated one). Prefer openrig-herdr unless cmux is specifically wanted.PlanningNo warnings★ 8.3K↓ —Also in 1 other repo
- django-storages-s3Jeffallan/claude-skillsUse when configuring Django to store static and media files on AWS S3 with django-storages. Invoke when working with the STORAGES setting, S3 buckets, presigned URLs, CloudFront, or boto3-backed file storage in settings.py. Configures the Django 4.2+ STORAGES dict, public/private custom backends, presigned GET/POST URLs, IAM policies, and S3 mocking for tests. Trigger terms: django-storages, S3, boto3, S3Boto3Storage, STORAGES, presigned URL, CloudFront, media files, collectstatic, AWS_STORAGE_BUCKET_NAME.TestingNo warnings★ 12.1K↓ —
- oversight-teammvschwarz/openrigUse when you are a seat on the oversight pod (a standing monitor-mode rig that keeps OTHER rigs healthy), configuring or running the drift detectors, or choosing whether to intervene vs escalate. Covers the pull-not-poll posture, the v0 detectors (premature-park, process-drift, off-task, token-burn), the intervention ladder (orchestrator-ping -> refocus -> human escalation), and the cheap+deep model economics. NOT for orchestrating your OWN rig (orchestration-team) and NOT the intervention primitive mechanics (watchdog).ProductivityNo warnings★ 8.3K↓ —Also in 1 other repo

- requirements-writermvschwarz/openrigUse when converting PM intake into a slice SPEC.md with observable acceptance outcomes, explicit scope, and advisory sibling build dependencies.WritingNo warnings★ 8.3K↓ —Also in 1 other repo
- openrig-herdrmvschwarz/openrigUse when opening OpenRig fleet terminals as a herdr wall — turning a rig, pod, mission, slice, or saved view into live interactive agent tiles via `rig terminal`, watching another rig read-only, or driving herdr on an agent's request ("open all my rigs + a mission as views"). Covers the `rig terminal open|views|status` verbs, the honest-partial/degrade reading of the result, the read-only-by-construction rail for cross-rig views, scroll/copy out of the box, and the same-size-only duplicate-pane limit. herdr is the default, proof-gated provider.OtherNo warnings★ 8.3K↓ —Also in 1 other repo
- seo-auditRyze-AI-Adgent/open-seo-mcp-skillsFull SEO audit of a site from its real Search Console + GA4 data — indexation health, CTR anomalies, decaying pages, striking-distance keywords, quick wins. Use when asked to "audit my site", "SEO audit", "why is my organic traffic down", or "SEO health check".MarketingNo warnings★ 7.7K↓ —
- elasticsearch-query-optimizationelastic/agent-skillsDiagnose slow Elasticsearch Query DSL searches and propose measured fixes. Use when a search is slow, profile output shows an expensive clause, exact-match filters sit in scoring context, or leading wildcards dominate latency. Ground every recommendation in search profiling — move non-scoring clauses to filter context, eliminate leading wildcards, and re-profile to confirm improvement.OfficialProductivityNo warnings★ 602↓ —Also in 1 other repo
- dogfoodmvschwarz/openrigSystematically explore and test a web application to find bugs, UX issues, and other problems. Use when asked to "dogfood", "QA", "exploratory test", "find issues", "bug hunt", "test this app/site/platform", or review the quality of a web application. Produces a structured report with full reproduction evidence -- step-by-step screenshots, repro videos, and detailed repro steps for every issue -- so findings can be handed directly to the responsible teams.TestingNo warnings★ 8.3K↓ —Also in 1 other repo
- specification-systemmvschwarz/openrigUse when authoring rig specs, agent specs, workflow specs, startup/context fragments, operating-mode declarations, or designing the user spec library. Covers the 4 failure modes (spec instantiates topology but not workflow/mode; spec depends on local paths and fails on another host; agents modify specs as one-off files instead of preserving reusable intent; validation proves YAML shape but not whether topology can run) and the validation-vs-runtime-realization distinction.PlanningNo warnings★ 8.3K↓ —Also in 1 other repo
- agent-startup-and-context-ingestionmvschwarz/openrigUse when designing or auditing how an agent becomes useful after launch — AGENTS.md overlays, role files, skills, rig specs, workflow specs, startup checklists, refocus messages, "rig context" surface. Covers the 4 failure modes that make startup context fail (old rig spec misses current operating mode; current agents never told about new guidance; startup file as dumping ground; orchestrator transmits implementation without preserving product intent).ProductivityNo warnings★ 8.3K↓ —Also in 1 other repo
- openrig-usermvschwarz/openrigUse when a specific `rig` command, subcommand, or flag is already known and you need its exact syntax, JSON shape, defaults, or error meaning. NOT for natural capability discovery, open-ended how-do-I questions, or choosing which OpenRig move applies.PlanningNo warnings★ 8.3K↓ —
- agent-operated-softwaremvschwarz/openrigUse when designing, building, operating, or diagnosing an ongoing application whose live backend or control loop includes OpenRig agents, including applications with a Markdown, YAML, or JSON agent control plane or a thin surface over specialist agent roles.PlanningNo warnings★ 8.3K↓ —
- skill-creatorGentleman-Programming/gentle-aiTrigger: new skills, agent instructions, documenting AI usage patterns. Create LLM-first skills with valid frontmatter.OtherNo warnings★ 8.1K↓ —
- go-testingGentleman-Programming/gentle-aiTrigger: Go tests, go test coverage, Bubbletea teatest, golden files. Apply focused Go testing patterns.TestingNo warnings★ 8.1K↓ —
- plan-reviewmvschwarz/openrigMulti-perspective review of a feature plan or requirements doc before development begins. Evaluates from strategy, design/UX, and engineering angles to catch gaps early.PlanningNo warnings★ 8.3K↓ —Also in 1 other repo
- hf-cloud-aws-context-discoveryhuggingface/skillsDiscover the user's local AWS context (active profile, region, account ID, caller identity) at the start of any AWS task. Use this skill before any other AWS work — deploying to SageMaker, creating resources, calling AWS APIs, or anything that touches an AWS account. Use it especially when the user has not specified a region or profile explicitly, when they say things like "use my AWS account", "deploy to AWS", "use my profile", or when about to make any AWS CLI or SDK call. Never guess the region or account ID — always use this skill to read it from the local configuration first.OfficialDevOpsNo warnings★ 11.2K↓ —
- architecture-designerJeffallan/claude-skillsUse when designing new high-level system architecture, reviewing existing designs, or making architectural decisions. Invoke to create architecture diagrams, write Architecture Decision Records (ADRs), evaluate technology trade-offs, design component interactions, and plan for scalability. Use for system design, architecture review, microservices structuring, ADR authoring, scalability planning, and infrastructure pattern selection — distinct from code-level design patterns or database-only design tasks.PlanningNo warnings★ 12.1K↓ —
- elasticsearch-index-designelastic/agent-skillsDesign and review Elasticsearch index mappings for stated access patterns: correct field types, text+keyword multi-fields, doc_values tuning, mapping-explosion avoidance, and explicit shard settings. Use when creating a new index, reviewing a mapping for storage or query performance, fixing wrong field types, or when the user asks which type to use for search, filter, sort, or aggregation on a field.OfficialDesignNo warnings★ 602↓ —Also in 1 other repo
