ASD-STE100 Skill

SimpleEnglish is an open-source agent skill that makes large language models write technical documentation in ASD-STE100 Simplified Technical English, a controlled language used in aerospace. Its rules enforce short sentences, active voice, explicit instructions, simple tenses, and consistent terminology when rewriting READMEs, error messages, incident reports, runbooks, and release notes. The skill is distributed as a dependency-free folder for tools that support the Agent Skills standard, including Claude Code, Cursor, VS Code Copilot, OpenAI Codex, Gemini CLI, Goose, and OpenCode. It can also be installed as a Claude Code plugin and output style, or used by adding its prompt to a system prompt, AGENTS.md, or .cursorrules file. The repository is licensed under MIT.

sepia is a portable Agent Skill for Claude Code, Codex, Grok Build, and Antigravity that revises AI-assisted fiction and professional prose at the narrative-architecture and discourse levels, rather than only changing word choice. For fiction, its three-pass protocol addresses narrative architecture, discourse flow, and surface style; its rules cover issues such as overly tidy causality, explained themes, linear time, sparse character networks, uniform emotional rendering, templated paragraph flow, and predictable endings. Professional-writing rules are matched to document venues including release notes, pull-request and issue replies, postmortems, tickets, and technical articles. The package provides write, review, refactor, and recreate operations, plus a general router. Review diagnoses without editing, refactor makes minimal in-place changes, and recreate rewrites from source facts and intent. It includes a 30-feature diagnosis rubric, model-specific fingerprint corrections, shared professional-prose checks, and research references. The repository distributes the skill as a plugin package with native installation paths for the supported tools and an alternative Skills CLI installation. It is licensed under the MIT License.

self-learning-skills is a meta-skill for AI coding agents, including Claude Code, Cursor, Codex, and agents that read AGENTS.md or similar standing-instruction files. It recognizes hard-won, reusable procedures such as non-obvious commands and recurring operational workflows, then captures them as skills, rules, or project instructions for later sessions. The capture includes known dead ends and excludes one-off details and secret values. The project stores learned procedures as new skills/<name>/SKILL.md files for Claude Code, Codex, and Agent Skills clients; as .cursor/rules/learned/<name>.mdc files for Cursor; or in AGENTS.md or project notes for other agents. It can be installed with the community skills CLI, as a Claude Code plugin, or manually by copying the relevant files.

AI Design Skills is an MIT-licensed collection of Markdown design skills for AI coding tools such as Claude Code, Cursor, Codex, Windsurf, and Cline. Its skills provide coding agents with guidance for landing-page strategy, page structure, conversion copy, typography, spacing, visual systems, border radius, and motion. Each skill is stored as a self-contained folder with a SKILL.md file that can be copied into an agent's project-rules directory, added to a system prompt, or uploaded to a Claude.ai project. The repository currently documents a landing-page-design skill that asks intake questions, builds the page structure and copy, and defines the visual system; its design values are grouped in an editable section so users can change fonts, colors, spacing, and motion. The collection can be forked and used, modified, distributed, or used in commercial work under the MIT license.

i-have-adhd is an open-source skill/plugin for coding assistants that formats responses as ADHD-friendly output. It leads with the next action, numbers multi-step tasks, suppresses tangents, restates state, gives specific time estimates, uses matter-of-fact errors, limits lists to five items, and ends with one concrete next step. The skill is installed through a coding assistant's CLI and can be customized by editing its SKILL.md file. It is licensed under the MIT License and does not require an ADHD diagnosis.
