Compact the current conversation into a handoff document for another agent to pick up. Configurable save location, redaction enforcement, SessionStart auto-load + SessionEnd reminder, self-check fidelity script, --refresh flag, mtime-guarded cleanup. Inspired by Matt Pocock's handoff (MIT).
PreToolUse security reminder hook for Claude Code. Catches 12 common security anti-patterns in Edit/Write/MultiEdit operations BEFORE they happen — command injection (exec, os.system, subprocess shell=True), XSS (innerHTML, dangerouslySetInnerHTML, document.write), SQL injection (f-string queries, .format), unsafe deserialization (pickle, yaml.unsafe_load), code injection (eval, new Function), and GitHub Actions workflow injection. Session-state caching prevents duplicate warnings; 30-day auto-cleanup. Disable per-session with ENABLE_SECURITY_REMINDER=0. Ported from David Dworken at Anthropic.
22 engineering documentation skills covering the complete software lifecycle.
documentation
Core Volcengine discovery, documentation search, CLI operations, troubleshooting, and voluntary community feedback skills.
core
Build, configure, authenticate, extend, document, operate, upgrade, and contribute to Backstage applications and the Backstage core repository with current first-party workflows, safety gates, and migration guidance.
Eight lean but firm skills, including spec-sync for durable intent and context-hygiene against stale documentation. They trigger only when their conditions match and stay strict once active. Includes a SessionStart discipline primer, passive local usage counting, and first-entry guide-doc seeding for CLAUDE.md / AGENTS.md.
Multimodal RAG, video search, image similarity search, agent memory, and embeddings stored with your data. Tables, computed columns, vector search, and video, audio, image, and document pipelines.
Author, validate, and blockwise-edit GEML documents, and navigate a project's call graph as GEML codemaps: two skills plus the geml MCP server (runs via npx @geml/geml, no separate install).
htmlify + deckify skills: agent answers become self-contained HTML documents and decks, validated by a bundled CLI. Optional Stop hook archives long answers automatically.
