Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Scored across 5 tools
Each tool has a clearly distinct purpose: get_skill retrieves files, install_skill downloads to local, list_repositories shows configured repos, search_skills finds matches by query, and suggest_skill_scaffold creates new skill templates. There is no overlap in functionality, making tool selection straightforward for an agent.
All tools follow a consistent 'github_skills_verb_noun' pattern, using snake_case throughout. The verbs (get, install, list, search, suggest) are distinct and appropriate for their actions, creating a predictable and readable naming scheme across the toolset.
With 5 tools, this server is well-scoped for managing GitHub-based skills. Each tool serves a unique and necessary function in the skill lifecycle, from discovery to installation and creation, without being overly sparse or bloated.
The toolset provides complete coverage for the domain of GitHub skill management: list and search for discovery, get and install for retrieval, and suggest for creation. There are no obvious gaps, enabling agents to handle the full workflow from finding to implementing skills.
