Three tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (get_user, create_repo, push_to_repo), which is good. However, descriptions are minimal (10-40 chars), parameter descriptions lack detail about constraints and formats, and output schemas are not documented. Error handling returns structured responses but lacks recovery guidance. No tool annotations (readOnlyHint/destructiveHint) despite clear risk differences between tools.

• Expand tool descriptions to 100-200 chars. Example: 'get_user: Retrieve GitHub user profile including login, name, bio, followers, and public repos. Use this to verify user existence or gather profile info before creating repos. Returns user_id, username, and profile_url for chaining to other tools.'
• Document output schemas for each tool. Specify which fields are returned (e.g., create_repo returns {repo_id, repo_url, repo_name, private, created_at}) so LLMs know what to extract.
• Add tool annotations: readOnlyHint=true for get_user; destructiveHint=true for create_repo and push_to_repo. This signals to agents which tools have side effects.
• Enhance parameter descriptions with constraints. Example: 'repo_name: Repository name (3-39 chars, alphanumeric + hyphens/underscores only, must be unique under authenticated user).'
• Improve error messages with recovery hints. Example: 'User not found. Try search_users() with a partial name, or verify the username spelling.' instead of raw API error.
