- hive.image-generationaden-hive/hiveRequired before calling image_generate. Create and edit images from a prompt — generate an image, make a picture / logo / illustration / icon / banner / poster / thumbnail / hero image / mockup / product shot / social graphic, or edit / restyle / combine existing images from reference images. Uses OpenAI gpt-image-2 through the Hive image service, billed to the user's Hive credits like an LLM call (no API key needed). Teaches the exact call shape, the quality/cost tradeoff (quality="low" is the default and cheapest), reference-image editing, how to show the result to the user with attach_file, and the failure modes (out of credits, model unavailable, moderation).MediaNo warnings★ 11.1K↓ —

- 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
- elasticsearch-ingestUpdatedelastic/agent-skillsLoad CSV, JSON, and NDJSON files into Elasticsearch indices using the bulk API and explicit mappings when field types matter. Use when batch-importing local files, converting CSV rows or JSON arrays to NDJSON bulk format, confirming cluster connectivity with elastic es info before ingest, or verifying document counts and mappings after ingest — not for Logstash pipelines, Beats, custom scripts, or index-to-index reindex.OfficialDataNo warnings★ 602↓ —Also in 1 other repo
- 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.

- observability-csp-investigationNewelastic/agent-skillsInvestigate cloud-provider (CSP) service issues — AWS today (the reasoning applies to any AWS service; schema and failure signatures are deepest for RDS, Lambda, SQS, ALB, EC2), and in future GCP and Azure — using OTel-schema cloud metrics in Elastic. Use when diagnosing cloud-resource problems, whether alert-triggered or ad hoc: database connection/CPU/memory pressure, function error rates and throttling, queue backlog and consumer lag, load-balancer 5xx, instance saturation. Correlates the resource under investigation against its own baseline, classifies the failure mode, and rules out co-occurring but unrelated conditions.OfficialDevOpsNo warnings★ 602↓ —Also in 1 other repo

Use when working with legacy or undocumented systems, inherited projects, or old codebases with no documentation. Invoke to map code dependencies, generate API documentation from source, identify undocumented business logic, figure out what code does, or create architecture documentation from implementation. Trigger phrases: reverse engineer, old codebase, no docs, no documentation, figure out how this works, inherited project, legacy analysis, code archaeology, undocumented features.PlanningNo warnings★ 12.1K↓ —

- elasticsearch-anomaly-detection-explainerelastic/agent-skillsExplain Elasticsearch ML anomaly detection scores, model behavior, and result interpretation. Use when the user asks why a score is high or low, how the model learns, what the numbers mean, or how to troubleshoot unexpected anomaly scores.OfficialOtherNo warnings★ 602↓ —Also in 1 other repo

From the author
claude-red is a curated library of offensive security skills designed for the Claude skills system. Each skill is a structured SKILL.md file that primes Claude with expert-level methodology for a specific attack surface — from SQLi to shellcode, EDR evasion to exploit development.
The frontmatter could not be read (no frontmatter); the folder name is shown instead.
