Builds editable Excel line and bar charts in a fixed house style with distributed labels.
Project overview
excel-house-charts creates native Excel line and bar chart objects with a fixed style for fonts, country colors, axes, legends, gridlines, and labels. Its helper distributes line-chart end labels and adds leader lines, while bar charts use a defined gap width and rotated value labels. openpyxl is required, and Gotham plus actual Excel are recommended because LibreOffice may not render manual label placement correctly.
Help LangGraph agents retrieve relevant tools from very large registries.
Project overview
langgraph-bigtool stores tool names, descriptions, namespaces, and other metadata in a LangGraph Store so an agent can search for relevant tools before calling them. It is designed for registries containing hundreds or thousands of tools, supports in-memory and PostgreSQL backends, and lets developers replace the default retrieval logic with a custom function.
Convert documents into legible, fax-ready 1-bit PDF or TIFF files.
Project overview
Use this skill or CLI to turn PDFs, office files, and images into fax-native 1-bit CCITT-G4 PDF or multipage TIFF while protecting small text, signatures, forms, and scans. It can produce comparison sheets and per-page reports so you can inspect readability before transmission. Office inputs require LibreOffice, while optional OCR improves text embedded in images at a substantial processing-time cost.
Give coding agents persistent memory through local Markdown files.
Project overview
pi-mem stores durable facts, daily logs, notes, and a scratchpad as plain Markdown, with tools for reading, writing, and keyword search. It can inject long-term memory, open tasks, and the latest daily logs into each agent turn while leaving older material available on demand. Installation targets the pi coding agent.
Generate and heal Playwright tests for SAP UI5 and Fiori applications.
Project overview
Praman turns a business-process description into planned, generated, and repaired Playwright tests for SAP GUI, UI5, WebGUI, and Fiori applications. For UI5-based interfaces, it queries controls through the runtime registry rather than relying only on fragile DOM selectors, while also offering typed fixtures for manual test authoring. It requires Node.js 22 and a compatible Playwright release.
Turn images into triangulated or polygonal art with an iterative algorithm.
Project overview
Triangula uses an iterative evolutionary algorithm to approximate an image with triangles or other polygons. Users can work through the separate graphical application or the companion CLI, which generates an intermediate JSON result and later renders it to SVG or PNG. The number of points and optimization settings can be adjusted for different styles and detail levels. Unlike instant geometric filters, the algorithm improves over repeated iterations and may need meaningful processing time before the result reaches the desired fitness.

ToolRAG
@antl3x·TypeScript
Retrieve only the most relevant tools for an LLM query
Project overview
ToolRAG registers tools from MCP servers, embeds their descriptions, and uses semantic retrieval to select the functions relevant to a user query. The selected definitions can be passed in an OpenAI-compatible format and executed against the corresponding servers, while LibSQL stores the tool index and embeddings. It is aimed at assistants that need access to many APIs without sending every tool definition on every request.
Build HTML and JavaScript desktop interfaces backed by Nim code.
Project overview
Neel helps Nim developers create desktop tools with a web frontend while retaining access to Nim on the backend. It handles routing, JSON conversion, and two-way calls between JavaScript and Nim, and release builds can embed the frontend assets. The library has been tested on macOS, Windows, and Linux, but it currently opens Chrome in app mode by default and is described as too early for large commercial applications.
Make HTML artifacts themeable with a shared, persistent color contract.
Project overview
Chameleon replaces hardcoded colors with a small semantic CSS contract that can be reused across HTML artifacts. Its Claude Code skill can create themed pages or propose a dry-run conversion for existing files, while a Chrome extension applies the reader's saved theme across compatible pages. For durable or offline artifacts, the theme can be baked into the HTML and pinned to a contract version.
Generate hierarchical drill-down tables for Excel, Word, and PowerPoint.
Project overview
Provide hierarchical data and drilldown-table renders the same corner-header report layout to XLSX, DOCX, or PPTX from one shared engine. It supports row, column, and two-dimensional drill-downs, uneven two-to-four-level branches, automatic totals, and three visual themes. Users can run it as a Claude or Codex skill, a Windows desktop app, a browser tool, or a Python library.
Build and verify interactive explanatory figures in plain HTML.
Project overview
Distill Figure helps developers build interactive explanations with plain HTML and ES modules. Its reusable components cover linked graphs, matrices, plots, controls, and chart wrappers, while the render and probe tools check multiple widths and real pointer or keyboard interactions. It is useful when visual polish must be accompanied by working interactions, without a bundler or framework.
Run SAP tabular classification and regression without model training
Project overview
SAP-RPT-1-OSS Predictor helps prepare SAP extracts and run classification or regression with SAP’s open-source tabular foundation model using in-context learning. It includes local prediction and batch-processing helpers, with an optional playground API path. A Hugging Face account is required, and a 24–80 GB GPU is recommended for the intended workloads.
Build restrained, data-led presentations with reusable HTML, CSS, and React pieces.
Project overview
Peg helps you create consistent slide decks and data-heavy presentations without starting in a design tool. It supplies opinionated HTML templates, CSS design tokens, React components, and entrance or transition animations built around typography, restrained color, and flat layouts. Chinese typography and reduced-motion preferences are handled explicitly, while static exports preserve the completed visual state.
Require independent review for high-impact agent decisions that demand hard correctness.
Project overview
Not So Fast checks whether an agentic decision was verified with enough independence for its difficulty and material impact. A self-only critic cannot approve a high-materiality, hard-correctness call; the guard instead requires an independent check or escalates when none is available. It ships as a Claude Code plugin, a SKILL.md folder, and a dependency-free Python guard with deterministic verdicts. The project presents this as a reference contract, not an empirically validated performance mechanism.

Decodes Solana transactions offline and gates them as SIGN, HOLD, or REJECT.
Project overview
sign-safe decodes an opaque Solana transaction before signing, classifies dangerous instruction shapes from the signer's perspective, and emits a SIGN, HOLD, or REJECT verdict plus machine-readable JSON. Its core requires no key, RPC, or broadcast; optional simulation and RPC enrichment are separate, and SIGN only means the transaction passed the current static policy.
Inspect Kleinanzeigen listings for seller, damage, duplicate, and vehicle warning signals.
Project overview
kleinanzeigen-reader parses a kleinanzeigen.de URL into structured listing details and highlights signals such as commercial sellers, declared damage, missing inspection dates, unusually high mileage, or duplicate ads. It can compare listings, export JSON reports, and download listing images from either the CLI or a Claude skill. The Python 3.8+ package has no third-party dependencies.
Use one ordered key-value database API in Node.js and browsers
Project overview
level is a convenience package that exposes a common abstract-level interface while selecting classic-level in Node.js and browser-level in web applications. It supports lexicographically ordered keys, batch writes, asynchronous iteration, encodings, and TypeScript declarations. Browser projects normally use it through a bundler such as Browserify, Webpack, or Rollup, while Node.js stores the database in a local directory.
Build extensible C++17 component systems behind stable interfaces.
Project overview
Velk helps C++ applications define components through interfaces with typed properties, events, functions, and metadata. Runtime implementations live in a shared library while consumers depend on stable public contracts, allowing internals to evolve without rebuilding every client. Its registries, plugin loading, object factory, and dense storage suit modular systems that need runtime extension and introspection.
