4.5k stars. A Claude Code Skill that turns a single prompt into a single-file horizontal-swipe HTML presentation deck — no build step, open in any browser. Ships 10 proven page layouts (cover, chapter divider, data table, image grid, quote callout, and more), 5 curated color themes (Ink Classic, Indigo Porcelain, Forest Ink, Kraft Paper, Dune), WebGL animated hero backgrounds, and three-tier typography (serif headline, sans-serif body, monospace metadata). Optional GPT-M 2.0 image generation integration for in-slide photographs and UI mockups. Distilled from real offline conference talks; enforces a strict design system rather than free-form generation.
Launched April 30 to all Enterprise customers (Team/Max access follows). Powered by Opus 4.7, Claude Security reasons over entire codebases the way a security researcher does — tracing data flows and cross-file interactions rather than matching known patterns. Public beta adds scheduled scans, CSV/Markdown export, and webhooks to Slack and Jira. Security platform integrations ship with CrowdStrike, Palo Alto Networks, SentinelOne, Trend Micro TrendAI, and Wiz. Anthropic says hundreds of organizations found vulnerabilities in production that existing tools had missed for years. Accessible at claude.ai/security from the Claude sidebar.
Shipped today (May 1, 02:05 UTC). Five notable additions: (1) `/model` picker now lists models from any gateway's `/v1/models` endpoint — works with custom Anthropic-compatible gateways without hardcoding models; (2) `claude project purge [path]` — one command deletes all Claude Code state for a project (transcripts, tasks, file history, config); (3) `--dangerously-skip-permissions` now also bypasses prompts for protected paths (.claude/, .git/, .vscode/, shell config files); (4) `claude auth login` accepts an OAuth code pasted directly into the terminal when browser callback can't reach localhost; (5) `claude_code.skill_activated` OpenTelemetry event fires for user-typed slash commands with an `invocation_trigger` attribute. Also: auto-mode spinner turns red when a permission check stalls, and PowerShell 7 detection improves on Windows.
36.3k stars. Turns any folder of code, docs, papers, images, or videos into a queryable knowledge graph wired into Claude Code via a PreToolUse hook. v0.5.0 benchmarks: 70x fewer tokens per search vs brute-force file reads. A PreToolUse hook intercepts every search, surfaces the 5–10 most relevant nodes, and injects only those into context — Claude never sees the rest of the repo. Covered by @charlieautomates as the core of their 'replaces OpenClaw' context-management stack.

24.5k stars. Tell Claude a topic and this skill researches it simultaneously across Reddit, X, YouTube (with full transcripts), TikTok, Instagram, HN, Polymarket, GitHub, Threads, Pinterest, Bluesky, and Perplexity, then synthesizes a grounded summary with upvote-scored community reactions. v3 adds intelligent entity resolution (types 'OpenClaw' → resolves to creator @steipete, r/openclaw, relevant TikTok hashtags), cross-source cluster merging, and GitHub person-mode (track an individual's commit activity). Created by Matt Van Horn (co-founder of June, acquired by Weber; a Lyft predecessor). Works in Claude Code, OpenClaw, and claude.ai web.
185k+ stars — clean-room Rust rewrite of the Claude Code agent harness, initiated April 1 after security researcher Chaofan Shou found the complete 512K-line TypeScript source in the npm package. Sigrid Jin (world's most active Claude Code user by token count) leads the project. 109k forks; active Discord; not affiliated with Anthropic.

493 stars (launched April 14). A production-grade MCP server that gives Claude 27 security intelligence tools across 21 APIs — eliminating the need to juggle NVD, EPSS, CISA KEV, MITRE ATT&CK, Shodan, VirusTotal, AbuseIPDB, GreyNoise, OSV.dev, GitHub Security Advisories, and more in separate browser tabs. Generates a composite 0–100 risk score using CVSS, EPSS, KEV status, and PoC availability. Eight tools work without API keys; graceful degradation when keys are missing. Outbound HTTPS only — no inbound ports, no telemetry, no API keys ever logged. Pairs directly with today's Claude Security public beta launch.
4.3k stars — TUI dashboard that shows where your AI coding tokens actually go, by reading Claude Code's JSONL session transcripts from disk (no proxy, no wrapper, no API key). Classifies every turn into 13 task categories, tracks one-shot success rates vs retry-burn spirals, and surfaces cost per task type across Claude Code, Codex, Cursor, and GitHub Copilot. macOS menubar app updated April 25.
Memory for Claude Managed Agents entered public beta April 23 under the standard `managed-agents-2026-04-01` header — no waitlist. Memories are stored as a workspace-scoped folder of Markdown files that agents read, write, and update using the same tools they already use. Early adopters: Netflix, Rakuten, Wisedocs (97% reduction in first-pass errors), Ando (30% speed increase in document verification). Audit trails log every memory change per session; memories are browsable and editable in the Claude Console.
34.5k stars, updated April 28 — production-grade multi-agent system combining 184 specialized AI agents, 16 orchestrators, 150 skills, and 78 focused single-purpose plugins for Claude Code. Three-tier model strategy built in: Opus for critical reasoning, Sonnet for complex tasks, Haiku for routine operations. New this week: PluginEval quality evaluation framework, Agent Teams plugin for parallel workflows, and Conductor plugin for context-driven track-based development.
