Tools

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.

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.

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.

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.

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.

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).

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.

Marketing team plugin with 40+ skills for copy and content, SEO and AI search optimization, conversion optimization, email and social, paid ads, growth strategy and competitor analysis, plus Python analysis scripts. Most need no account; a few, like YouTube transcripts, need API keys.

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.

Helps turn a fuzzy intention into a concrete, measurable goal before work starts: outcome, verification evidence, success threshold, scope and stop conditions, then creates it with the goal tool (get_goal, create_goal). From OpenAI's official skills repo.

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.

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.

Graph-based task tracking and memory for coding agents: a dependency graph replaces Markdown plans, agents claim ready work with bd ready and keep context across sessions. The plugin injects workflow instructions through hooks. Requires the bd CLI.

Graph-based task tracker CLI (bd) for coding agents: replaces Markdown plans with a dependency-aware task graph that gives long tasks persistent memory. Stored in Dolt and syncable across machines; bd init hooks it into Claude Code and Codex automatically.

Manus-style file-based planning: writes the plan, findings and progress to three Markdown files and injects them into context each turn via hooks, so the agent resumes from the current phase after /clear, compaction or a crash. Supports Claude Code, Codex and many other agents.

Keeps the plan, research findings and progress in three files (task_plan.md, findings.md, progress.md) and injects them every turn via hooks, so work resumes after /clear, context compaction or an interrupted session. A Chinese-language variant is also available.

Proofreads drafts: once you explain the text's purpose, it finds grammar, logic and flow issues and gives located suggestions with reasons, without rewriting the whole piece or changing your voice. Rules and examples target English. Part of PM Skills; no extra account needed.

The MCP server built into the Angular CLI (ng mcp): lets agents search the official angular.dev docs, get best practices, list workspace projects, start the dev server and run build and test targets. Supports read-only and offline modes. Maintained by the Angular team.

Baoyu's (JimLiu) content creation skills: infographics, covers, article illustrations, slide decks, comics and translation, plus Xiaohongshu cards and publishing to WeChat, Weibo and X. Needs Node.js, bun and an image model API key; some skills rely on Chrome automation or unofficial APIs.
