KCC is a cross-platform comic and manga converter for Kindle, Kobo, reMarkable, and other E Ink readers. It processes image folders, comic archives such as CBZ and EPUB, and PDFs, then resizes pages to device profiles, crops margins and page numbers, adjusts contrast and black levels, supports manga and webtoon layouts, and detects or splits two-page spreads. It can produce MOBI/AZW3, EPUB/KEPUB, CBZ, PDF, or image-folder output, with GUI and command-line tools for Windows, macOS, and Linux. The project also includes processing intended to reduce the rainbow effect on Kaleido 3 displays using a 2D discrete Fourier transform. KCC is released under the ISC license and is maintained in the ciromattia/kcc GitHub repository.

Hallmark is an open-source design skill for Claude Code, Cursor, and Codex that applies anti-AI-slop rules to generated interfaces. It selects a macrostructure and one of twenty-one themes for a brief, applies its design rule set, runs fifty-seven anti-pattern gates and a pre-emit self-critique, and returns self-contained HTML and CSS. Its four operations build new UI, audit existing code without editing it, redesign an interface while retaining its copy, information architecture, and brand, or study a screenshot or URL to extract macrostructure, type pairing, and a color anchor; the study operation can also emit a portable design.md file. Custom briefs can receive a made-to-measure palette, typography, and layout rather than a catalog theme. Hallmark is made by Together AI and distributed under the MIT license.

Krbn, pronounced “Carbon,” is an open-source TypeScript web engine for non-photorealistic, pencil-style rendering of 3D scenes to SVG. It is intended for abstract and technical scenes, with medical and organic illustration described as a future direction. Rather than rendering surfaces as pixels, Krbn derives, classifies, and styles strokes from geometry. Its analytic primitives produce exact silhouettes such as conics and the true quartic of a torus; hidden lines are split into visible and ghosted runs; intersections are solved using low-degree polynomial roots; and triangle meshes pass through the same rendering pipeline. Hatching provides shading and transparency through stroke density and direction, including curvature-following patterns such as sphere parallels and meridians, torus loops, and streamlines on arbitrary meshes. Scene semantics such as importance, focus, and role guide what the engine draws, ghosts, or abstracts. The pipeline includes hidden-line visibility, suggestive contours, hand-drawn wobble, and variable-width strokes. Wobble is seeded from stable stroke identities so animated camera movements do not cause the lines to boil between frames, and the project aims to emit deterministic, byte-identical SVG on a given platform. It supports scene and animation construction through an API, with examples including STL and OBJ imports and an animated camera orbit. Krbn is MIT-licensed.

Kool Brushez is a p5.js drawing app with six independent brushes: Score draws flowing musical-staff ribbons, Schematic creates drafting diagrams, Balloon reveals airbrushed shapes, Subway generates branching transit lines, Crowd draws animated people, and Gunpla grows model-kit sprues. All brushes use one shared canvas, so users can switch between them without reloading or losing existing marks; each brush has its own JavaScript drawing algorithm, settings, preview, and registry entry. The app provides brush-specific controls, auto-fill and variation modes, undo and redo, erasing across brushes, aspect-ratio fitting, keyboard shortcuts, touch and pen input, and PNG export. It is built with Vite, plain JavaScript and CSS, and is released under the MIT License.

text-to-cad is a library of agent skills for creating, inspecting, sourcing, slicing, previewing, and handing off CAD, CAE, CAM, robotics, and hardware-design artifacts from local project files. Its skills generate and edit CAD models from plain-language or image requests, primarily producing STEP files with optional STL, 3MF, and GLB exports; preview local CAD and robot files in a browser; source off-the-shelf STEP parts; and create DXF drawings from Python sources or CAD geometry. Additional skills write URDF robot structures, SRDF/MoveIt2 planning and collision data, and SDF simulator models and worlds; check DXF and STEP files for SendCutSend; measure mesh printability by wall thickness, overhangs, support volume, and build orientation; slice supported meshes into validated, printer-profiled FDM G-code using slicer command-line tools; and dry-run, upload, and cautiously start local Bambu Lab print jobs. An experimental implicit-CAD skill creates browser-native models with GLSL signed-distance fields and CAD Viewer raymarch rendering. The library is installed with the Skills CLI, including `npx skills add earthtojake/text-to-cad`, or through provider-native plugins for Codex, Claude Code, and Grok Build.
