skill-creator skillA
skill-creator is agent-read markdown (skill) from starchild-ai-agent/official-skills: Scaffold new skills with valid frontmatter, directory layout, and a starter SKILL.md. Use when building a new reusable workflow or wrapping a new API (e.g. create a kalshi skill, scaffold an API helper, start a charting skill)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
## Core Principles **Concise is key.** The context window is a shared resource between the system prompt, skills, conversation history, and your reasoning. Every line in a SKILL.md competes with everything else. Only add what you don't already know — don't document tool parameters visible in the system prompt, don't prescribe step-by-step workflows for things you can figure out. Focus on domain knowledge, interpretation guides, decision frameworks, and gotchas. **Progressive disclosure.** Skills load in three levels: 1. **Always in context** — name, emoji, and description appear in `<available_skills>` in every conversation. This is how you decide which skill to activate. The description must be a strong trigger. 2. **On activation** — the full SKILL.md body is loaded via `read_file` when you decide the skill is relevant. This is where workflow, guidelines, and decision trees live. 3. **On demand** — scripts/, references/, and assets/ are only loaded when explicitly needed. Heavy content goes here, not in the body. …
