mono-color-skill

# Technical Review: mono-color-skill (v1.2.0) `mono-color-skill` is a structured visual design system packaged as an open-source `SKILL.md` configuration for AI agents such as Anthropic's Claude Code. Built to translate raw themes, text prompts, or photographic inputs into print aesthetics (such as zines, packaging, and posters), it constrains generative output using defined mechanical print parameters rather than loose visual prompt descriptions. ### Architectural Logic & Rendering System Instead of allowing an image generator to drift stylistic decisions, the skill embeds a strict visual system under the hood: * Plate Mechanics: The rendering engine defaults to a controlled two-ink setup composed of one dominant ink plate paired with a single, narrowly assigned accent plate (e.g., cobalt and terracotta or violet and orange). When monochrome or single-ink outputs are explicitly requested, the system bypasses the accent layer entirely to enforce a pure one-ink plate. * Substrate Dynamic: Background stock selection is tied directly to the source image and selected color palette, picking strictly between stark white, cool gray, or pale-beige paper substrates. * Aesthetic Rules: Contemporary editorial layout serves as the default visual mode. Vintage treatments are sandboxed and will only apply if explicitly called out in the prompt context. * Compositional Reconstruction: Rather than performing a straight filter pass or simple image copy, the system evaluates the subject, intent, text, and image role to rebuild the layout around active negative space, halftone photographic processing, and restrained typography. ### Repository Structure & Workflow Validation The repository maintains a lightweight footprint focused on agent-level deployment: * `SKILL.md`: The core rule-definition file consumed by the AI agent. * `CHANGELOG.md`: Tracks release versions (currently at version `1.2.0`). * `README.zh.md`: Provides Chinese localization alongside the main English documentation. * `examples/`: Contains benchmark renders across various utility domains, including packaging design (sardine tins, headphone boxes, sunscreen), visual field notes, and editorial posters. Continuous integration is handled via GitHub Actions. The repository includes a validation pipeline (`.github/workflows/validate.yml`) designed to check and validate the skill definition against expected structural rules. ### Setup and Agent Integration To run `mono-color-skill` within Claude Code or any compatible `SKILL.md`-compliant agent setup: 1. Clone or copy the `SKILL.md` file into your project or agent skill directory. 2. Ensure your execution workflow references `SKILL.md` when initiating prompt tasks. 3. Supply a raw topic, photograph, or design concept (e.g., brand merchandise, leaf photography, or radio zine layouts). Once loaded, the agent automatically maps your input against the ink plate constraints, halftone rules, and substrate guidelines defined in the skill file, outputting production-style print concepts without needing manual styling flags.
