Tools

Universal psql-style SQL command line: one tool to connect to PostgreSQL, MySQL, SQLite, SQL Server, Oracle and dozens of other SQL and NoSQL databases, with support for copying data between databases.

Open-source research agent: one command runs literature reviews, deep research, paper reviews, paper-code consistency checks and replication plans, searching arXiv, PubMed and more with sources recorded. Good for grad students writing reviews. Run feynman setup to sign in to a model provider.

Processes CSV, TSV, JSON and other structured data like awk, sed, cut, join and sort, but by field name, for cleaning, aggregation, format conversion and pretty-printing. The command is mlr; written in Go with no runtime dependencies.

Linter and formatter for 20+ SQL dialects that auto-fixes most issues and handles Jinja templating and dbt projects (dbt needs a plugin), suited to warehouse code review and CI.

NVIDIA's open-source LLM vulnerability scanner that probes for prompt injection, jailbreaks, data leakage, hallucination and harmful content, supporting OpenAI, Hugging Face, Bedrock and most REST-accessible models. Scanning cloud models needs their API keys.

Anthropic's official AI governance plugin: tiers AI use cases against your internal register, runs impact assessments across applicable laws such as the EU AI Act, reviews vendor AI terms for training-data and liability risk, and periodically checks for drift between AI policy and practice.

Privacy compliance plugin: decides whether processing activities need a PIA or DPIA, generates privacy impact assessments, reviews DPAs from the controller or processor side, and drafts DSAR responses within statutory deadlines. Official from Anthropic.

Anthropic's official product counsel plugin: learns your risk calibration from past launch reviews, then reviews launches, checks marketing copy for claims needing substantiation and quickly answers is-this-OK questions. Connects to Jira, Linear and Slack; outputs are drafts for attorney review.

Official skill for Anarlog (formerly Hyprnote), an open-source, local-first meeting notes app: lets agents query notes, summaries, transcripts, attendees and action items from local data, with no meeting bot needed. Requires the Anarlog desktop app and CLI; remote cloud access needs Pro.

High-accuracy retrieval-augmented Q&A over paper PDFs, text and Office documents, filling in citation metadata, checking retractions and attaching traceable sources to answers. Provides the pqa CLI and a Python library. Needs an LLM API key by default; local models can be configured.

Terminal tool for exploring and wrangling tabular data: opens dozens of formats including CSV, JSON, Excel and SQLite for filtering, sorting, pivots and frequency counts. --batch mode replays actions headlessly or converts file formats.

Say build a harness for this project and it designs a domain-specific agent team, generating subagent definitions, companion skills and orchestration, validates them and keeps evolving them from feedback. Supports workflow orchestration, persistent agent teams and subagent delegation.

Static scanner for security and compliance issues in Terraform, CloudFormation, Kubernetes, Helm, Dockerfiles and CI pipeline configs, with over a thousand built-in policies and hard-coded secret detection. Outputs SARIF, JSON and more. Maintained by Prisma Cloud.

Companion skills for Google Stitch: generate UIs from text or images, extract DESIGN.md from code, and turn designs into React or React Native components. From Google Labs but not an officially supported Google product; set up the Stitch MCP first.

Spec-driven project management for software: guides brainstorming into a PRD, breaks it into epics and dependent tasks synced as GitHub Issues, answers standup, next-step and blocker questions, and can dispatch several agents to code in parallel. Needs Git, an authenticated gh CLI and a GitHub repo.

Turns Peng Sida's public research-writing notes into a skill: revises abstracts, introductions, methods and experiments of ML/CV/NLP papers from a reviewer's view, checks that each claim has experimental evidence, and runs a pre-submission self-check. Pure methodology, no API key.

Offline speech toolkit for Apple Silicon Macs: CLI text-to-speech (including Chinese and voice cloning) and speech-to-text, for voicing lessons and explainer videos or transcribing lectures and interviews, with data staying local. Needs an M-series Mac and Python 3.10+; MP3 export needs ffmpeg.

From Trail of Bits: starts from one confirmed vulnerability, distills its root cause, then writes and progressively generalizes CodeQL/Semgrep queries to find similar variants across the codebase and report them by severity.

Trail of Bits skill that audits npm, PyPI and Go supply-chain risk: known advisories across direct deps and the whole lockfile tree, deprecated or archived upstreams, npm publisher concentration and install-time scripts. Needs uv; a logged-in gh is recommended.

Trail of Bits skill that audits GitHub Actions workflows wired to AI coding agents (Claude Code Action, Codex, Gemini CLI and others) for prompt injection, env-variable relays, dangerous sandbox settings, wildcard allowlists and other privilege risks.

Plugin marketplace from security firm Trail of Bits with 40+ plugins for code auditing, CodeQL/Semgrep static analysis, variant analysis, supply-chain risk, smart contract security and reverse engineering. Codex can load it directly too.

From Trail of Bits: reviews PRs, commits or diffs from a security angle, tracing history with git blame, estimating blast radius by caller count and checking test coverage gaps, then writes a Markdown review report.

Trail of Bits static analysis skills: CodeQL for interprocedural taint tracking and data-flow analysis, Semgrep for rule-based scanning, plus parsing and deduplicating SARIF results. Requires CodeQL or Semgrep installed locally.

Plugin marketplace of 77 product management skills based on JTBD, opportunity solution trees, RICE and other proven methods, covering user interviews, PRDs, roadmaps, prioritization, market sizing and product sunsets. A Codex skill pack is also available.
