Create and iterate on Agent Skills with proper structure, frontmatter, and progressive disclosure. Make sure to use this skill whenever the user asks to build a new skill, create an agentic instruction, generate a SKILL.md, or automate a workflow into a reusable package, even if they don't explicitly use the word "skill".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Skill Creator
## 1. Capture Intent
Start by understanding the user's exact intent. The current conversation might already contain a workflow the user wants to capture (e.g., they say "turn this into a skill"). If so, extract answers from the conversation history first:
* **Workflow Elements:** Identify the tools used, the sequence of steps, corrections the user made, and input/output formats observed.
* **Environment & Scope:** Determine the target context (e.g., Firebase edge functions, Supabase RLS policies, or Cursor IDE environments) and whether the skill is global or isolated to a specific project boundary (e.g., AuraDocs or Energise).
* **Test Cases:** Skills with objectively verifiable outputs (code generation, data extraction, file transforms) benefit from test cases. Skills with subjective outputs often don't need them. Suggest the appropriate default, but let the user decide.
## 2. Interview and Research
Proactively ask questions about edge cases, input/output formats, example files, and success criteria.

The line at the top of this page pins the label v1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
