Tools

PostgreSQL command-line client with smart autocompletion and syntax highlighting. Compatible with psql environment variables, and -c runs a statement and exits, so agents can query databases non-interactively.

Customizes the Claude Code status line to show model, Git branch, token and context usage, session and weekly limits at the bottom of the terminal. Configured through an interactive TUI with Powerline styling. Claude Code only.

Runs an extremely strict maintainability review of the current branch: hunts for restructurings that make the change dramatically simpler and flags files pushed past 1,000 lines, ad-hoc conditionals, thin wrappers and needless casts. From Cursor's official plugins; invoke manually.

Simon Willison's LLM CLI and Python library: call OpenAI, Claude, Gemini and local models from the terminal, with conversations logged to SQLite automatically, plus embeddings, structured extraction, tool calling and a plugin system.

From Zilliz: indexes your codebase as vectors in Milvus or Zilliz Cloud so coding agents find relevant code by semantic search, cutting context costs in large repos. Needs an embedding model (OpenAI, VoyageAI, Ollama and others) and a vector database.

A du replacement written in Rust that shows disk usage as a directory tree with proportion bars, making large files and folders easy to spot. Filter by depth, count or regex, and output JSON with -j for agents to parse.

Lets agents call thousands of ready-made scrapers and automation Actors from Apify Store to pull data from social media, search engines, maps, e-commerce sites and more. Maintained by Apify; needs an Apify account (OAuth) or API token.

ByteDance's open-source, general software engineering agent: trae-cli edits files and runs commands from natural language, supports multiple model providers and MCP, and records full execution trajectories. Transparent design suits agent research and customization. Needs your own model API key.

MySQL terminal client with smart autocompletion and syntax highlighting, also compatible with MariaDB and TiDB. Supports --execute and batch mode with CSV or table output, so agents can run SQL directly.

Bundles 60+ full-stack specialist skills into one plugin: experts for 12 languages including Python, TypeScript, Go, Rust and Java, and frameworks like React, Django and Spring Boot, activated automatically by request. Also includes Jira and Confluence workflow commands (needs Atlassian MCP).

Connects to the Arize Phoenix observability platform so agents can query LLM traces and sessions, manage prompts, browse datasets and read experiment evaluation results. Maintained by Arize; needs a self-hosted or cloud Phoenix instance.

Lets Claude Code, Codex and other agents call Gemini, GPT, Ollama and other models to collaborate on code review, debugging, planning and multi-model consensus, and can bridge to other CLI agents. Configure at least one provider (API key or local Ollama). Formerly Zen MCP.

Reads local session files to report token usage and cost by project, model, task and branch for Claude Code, Codex, Cursor and dozens of other coding agents, no sign-up needed. Also offers config optimization tips, quota checks and spend-cap hooks. Needs Node.js 22.13+.

Publishes SQLite databases as browsable, queryable web pages and JSON APIs, with SQL queries, metadata and plugins, and deploys to Cloud Run and other platforms with datasette publish. Great for data exploration and data journalism. Needs Python 3.10+.

Scans files and directories for personal data such as names, emails and credit card numbers using Presidio Analyzer, with configurable entity types, confidence thresholds and ignore rules. Needs Python 3.10+ and a spaCy language model.

GitHub's official terminal coding agent, sharing its harness with the Copilot coding agent and shipping with the GitHub MCP built in. Work with repos, issues and PRs in natural language, approving each action before it runs. Requires a Copilot subscription.

Google's official dependency vulnerability scanner: parses project lockfiles and container images, checks them against the OSV.dev database to find affected dependencies, and can suggest upgrade fixes (experimental).

Teaches agents the Hugging Face Hub CLI hf: search and download models, manage datasets, Spaces, Buckets and repos, and run Jobs and inference endpoints. The skill content is generated from your local CLI, so install hf first. Maintained by Hugging Face.

Lets agents fine-tune language and vision models with TRL or Unsloth on Hugging Face Jobs cloud GPUs, supporting SFT, DPO, GRPO and reward models, and convert results to GGUF for local use. Requires an HF Pro or higher paid plan. Maintained by Hugging Face.

Hugging Face's official skills: manage Hub models and datasets with the hf CLI, fine-tune language and vision models, run model evaluations, and build Gradio apps deployed to Spaces. Needs an HF account; cloud training on HF Jobs requires a paid plan.

Lets agents work with the Hugging Face Hub through the hf CLI: search and download models and datasets, manage repos and Spaces, and run training and evaluation jobs on cloud GPUs, with more workflow skills installable as needed. Maintained by Hugging Face.

OpenAI's official security CLI and TypeScript SDK: scans codebases to find, validate and fix security vulnerabilities, and can draft a SECURITY.md policy. Needs Node.js 22.13+, Python 3.10+, and a ChatGPT sign-in or API key.

The official MCP debugging tool: connect to any MCP server through a web UI, CLI or terminal UI to list and call its tools, resources and prompts. CLI mode outputs JSON, suited to scripts and CI smoke tests.

Spec-driven development and context engineering framework (formerly Get Shit Done): a five-step loop of discuss, plan, execute, verify and ship, handing heavy work to subagents with fresh context to avoid degradation in long sessions. Supports Claude Code, Codex and more.
