Tools

Rendering engine that lays out HTML and CSS and exports PDF, supporting paged media and other print style standards, ideal for generating reports, invoices and receipts in bulk. Written in Python; depends on the system Pango library.

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.

Manage database schemas as code: declare the desired schema in SQL, HCL or your ORM and Atlas plans, lints and applies migrations, and can export existing databases as HCL, SQL or Mermaid ER diagrams. Supports PostgreSQL, MySQL and a dozen other databases.

Manages multiple Claude Code, Codex, Gemini and Aider sessions in parallel from one terminal: each task gets its own git worktree, can run in the background, and changes are reviewed before merging. Requires tmux and gh.

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.

Converts the output of 100+ commands such as dig, ps, ls and ifconfig, plus common file formats, into JSON so agents can parse it reliably with jq or scripts. Also usable as a Python library.

Free remote MCP service that turns any GitHub repo or GitHub Pages site into a docs endpoint, so agents can read up-to-date docs and search code on demand and hallucinate fewer APIs. No sign-up or install; self-hosting is also possible.

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.

Moonshot AI's official terminal coding agent: reads and edits code, runs commands, searches files and fetches web pages, with video input, MCP, plugins, subagents and hooks, plus Zed and JetBrains integration via ACP. Needs a Kimi sign-in or Moonshot API key. Replaces the archived Kimi CLI.

HTTP client CLI that reimplements HTTPie's syntax in Rust with a focus on performance; key-value pairs on the command line are sent as JSON by default, making it quick to debug REST APIs.

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 plugin for Culture Index assessments: profiles individual traits, checks team balance (gas, brake, glue), compares people with job profiles to flag burnout and attrition risk, and helps draft hiring profiles. Needs your own reports (JSON or PDF); PDFs need uv.

Query, modify and convert JSON, YAML, TOML, XML, CSV, HCL, INI and more with one selector syntax, editing config files in place or converting between formats, handy for agents handling structured data in scripts. A single dependency-free binary that works much like jq or yq.

Diffusion model inference in pure C/C++: one sd-cli command runs SD, FLUX, Qwen Image, Wan and more locally to create or edit images and short videos, with Metal acceleration on Mac. No cloud needed; bring your own model weights and use a release binary or build from source.

77 product management skills built on JTBD, opportunity solution trees, RICE, Working Backwards and other proven methods: user interviews, PRDs, roadmaps, prioritization, competitive intel, market sizing and sunsetting, explaining the frameworks as they go. CC BY-NC-SA licensed.

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.

Builds, refactors and debugs ChatGPT apps with the OpenAI Apps SDK: plans tools, scaffolds the MCP server and UI widgets, and checks the work against official docs. Maintained by OpenAI; formerly chatgpt-apps in openai/skills.

OpenAI's official Codex plugin marketplace (openai-curated) with 60+ plugins such as Figma, Notion, GitHub, Stripe and Vercel, each bundling skills, MCP servers and app connections into one install.

Turns conversations and notes into structured Notion pages such as team wikis, how-to guides, decision records and FAQs, linked to related pages. From OpenAI's official plugin repo (developer: Notion); needs the Notion MCP.

Granola's official plugin in OpenAI's Codex marketplace: search past Granola meeting notes by topic, person, company or date, and cite the discussions and decisions when writing proposals, reports or analyses. Codex only; needs a Granola account already recording meetings.
