Data analysis plugin: writes queries in each SQL dialect, explores datasets, runs statistical tests, charts with Python and builds interactive HTML dashboards, then reviews methods and conclusions before sharing. Connects to Snowflake, BigQuery and other warehouses. Official from Anthropic.

Runs commands and scripts in a sandbox, indexes large tool outputs for full-text search and returns only results to the context window to save tokens; after compaction it can retrieve edits and task state. Supports Claude Code, Codex and more. Needs Node.js 22.5+.

Processes large tool outputs in a sandbox and returns only the results to context; logs session events in SQLite with FTS5 so work continues after context compaction. Supports Claude Code, Codex and a dozen other clients. ELv2 licensed.

Anthropic's official data skill that guides agents to write, translate and optimize SQL across Snowflake, BigQuery, Databricks, PostgreSQL and other warehouse dialects, including CTEs, window functions and analytical aggregations.

Synthesizes user feedback from interview notes, surveys and support tickets into themes ranked by frequency and impact, and outputs structured insights and roadmap recommendations. Can pull data from knowledge bases or meeting transcripts. From Anthropic's official product-management plugin.

Everyday software engineering plugin: standup summaries, code review, structured debugging, architecture decision records, incident response and pre-deploy checks. Official from Anthropic, built mainly for Cowork but also usable in Claude Code.

Plugin for design teams: design critiques, design system audits, UX copy, accessibility checks, user research synthesis and developer handoff notes. Official from Anthropic; works best with Figma connected.

Official web auditing tool from the Google Chrome team: score pages on performance, accessibility, best practices and SEO from the command line and get HTML, JSON or CSV reports, so agents can iterate on a page. Needs Node 22+ and Chrome.

Gives coding agents IDE-like symbol-level code search, editing and refactoring via language servers (LSP) across 40+ languages, with cross-session memory. An optional paid JetBrains plugin backend adds breakpoint debugging. Install with uv first.

Open-source infrastructure-as-code tool and community fork of Terraform: describe cloud resources declaratively, run plan to generate an execution plan, then apply changes, creating resources in parallel by dependency graph. Community-governed, MPL-2.0.

Turns websites and Electron desktop apps into deterministic CLIs, with built-in adapters for Reddit, Hacker News, Bilibili, Zhihu, Xiaohongshu and more, and lets agents operate any page through your signed-in Chrome. Needs its companion browser extension.

Kubernetes package manager that packages, installs, upgrades and rolls back releases with Chart templates, including ready-made charts from Artifact Hub. A CNCF graduated project; needs a kubeconfig to reach your cluster.

Detects hardcoded passwords, API keys and tokens in Git repos, files and stdin, and can run as a pre-commit hook or GitHub Action to block leaks. Now feature-frozen with security fixes only, as the author has moved on to Betterleaks.

Packs a whole repository into a single AI-friendly file (XML, Markdown, JSON or plain text) with per-file token counts, automatically excludes files containing secrets, and can compress code with Tree-sitter or pack remote GitHub repos directly.

Status line plugin for Claude Code showing the model, Git branch, context usage and rate limits live below the input, optionally with running tools, active subagents and todo progress.

Terminal coding agent from Charm: switch models mid-session while keeping context, manage multiple sessions per project, pull code context via LSP, and extend with MCP and any OpenAI- or Anthropic-compatible API.

Open-source terminal coding agent from Alibaba's Qwen team with subagents, auto memory, skills and MCP. Works with Qwen, OpenAI, Anthropic, Gemini and other APIs or local models, with IDE plugins and a headless mode (qwen -p).

Finds leaked credentials in Git, GitHub, S3, filesystems and more, recognizing 800+ secret types and checking with each service whether a key is still live to cut false positives.

A collection of 380+ skills across engineering, product, marketing, compliance, finance and executive advisory roles, with many standard-library Python scripts. Claude Code can install them by domain as plugins; works with Codex, Gemini CLI and a dozen other agents.

Large multi-domain plugin marketplace: 99 plugins bundle hundreds of skills, agents and slash commands covering engineering, marketing, product, project management, regulatory and quality, finance and C-level advisory. Also offers install options for Codex, Gemini CLI and others.

Google Labs' DESIGN.md format and CLI: designers capture colors, typography and spacing in a file for agents; lint checks broken references and WCAG contrast, diff compares versions and export outputs design tokens for Tailwind and more. Needs Node.js; the format is in alpha.

Parses a PRD into a dependency-aware task list so Cursor, Claude Code and other coding agents break it down, implement it and track progress; also works as a CLI. Needs at least one model API key, or reuse a Claude Code or Codex CLI login.

Parses a PRD into a dependency-aware task list so Claude Code, Cursor and other agents pick up the next task in order, split subtasks and update progress. Offers both a CLI and an MCP server. Needs at least one model API key, or reuse a Claude Code or Codex login.

Parses a PRD into a dependency-aware task list with complexity analysis, task breakdown and research; the plugin bundles slash commands, subagents and the MCP server. Needs a model API key, or reuse a Claude Code or Codex CLI login.
