Extend standard agentskills.io skills with Claude Code-specific features. Invocation control, subagent execution, dynamic context injection, string substitutions, model/effort overrides, and deployment scoping. Use when adapting a portable skill for Claude Code, adding Claude-specific frontmatter, setting up subagent delegation, or configuring skill permissions.
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.
What the file says
# Extend OSS Skills to Claude Code > **Prerequisite:** read `create-oss-skill` first. That skill owns the base agentskills.io format and shared reference material (description optimization, eval workflow). This skill contains only the Claude Code-specific deltas (invocation control, subagent execution, dynamic context injection, model/effort overrides, deployment scoping). Take a standard [agentskills.io](https://agentskills.io/specification) skill and layer on Claude Code execution features. The base spec defines a portable file format; Claude Code turns it into an execution framework. ## What the Standard Covers The open standard defines: `name` (required), `description` (required), `license`, `compatibility`, `metadata`, `allowed-tools` (space-delimited). These fields work across all compatible agents (Cursor, Gemini CLI, OpenCode, Goose, etc.). Start with `create-oss-skill` for the base format. ## Claude Code Extended Frontmatter These fields are Claude Code-specific. Other agents ignore them. | Field | Type | Default | Purpose | |-------|------|---------|---------| | `argument-hint` | string | none | Autocomplete hint: `[issue-number]`, `[filename] [format]` | …

How to install
mdr add urmzd/dotfiles/extend-oss-skills-to-claude@sha256:efa1040960c9511cThe line at the top of this page pins the label git:20260530.d3be4dd, 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.
