Server has 9 tools with basic descriptions and parameter schemas, but significant gaps limit production readiness. All tools have descriptions (10-50 chars baseline), but most are terse and lack context for LLM selection. Parameter schemas are present with type and description fields, meeting minimum JSON Schema requirements. However, no output schemas are documented, error handling is absent, and security concerns around shell command execution are unaddressed. GitHub tools lack pagination support despite returning lists. No tool annotations (readOnlyHint/destructiveHint) despite clear risk stratification. run_command is particularly dangerous, accepts arbitrary shell input with no validation, sanitization, or confirmation pattern.

• Add tool annotations: mark read-only tools with readOnlyHint=true (get_repo, get_file, list_pull_requests, list_issues); mark destructive tools with destructiveHint=true (create_branch, create_pull_request, create_issue, create_fork, run_command); mark idempotent tools with idempotentHint=true where applicable.
• Document output schemas for all tools. Example for get_repo: {type: 'object', properties: {full_name: {type: 'string'}, description: {type: 'string'}, default_branch: {type: 'string'}, stars: {type: 'integer'}, url: {type: 'string'}}}.
• Add pagination to list_pull_requests and list_issues: accept limit (1-100, default 20) and offset parameters; return total_count and has_more fields. Cap results at 20 by default per mxe:enforce-result-limits.
• Expand run_command description to 100+ chars explaining it executes shell commands with full output capture. Add critical security note: 'Validate and sanitize all command input to prevent injection attacks. Consider requiring confirmation for destructive operations (rm, kill, etc.)'
• Enhance GitHub tool descriptions (50→150 chars): explain when to use each (e.g., 'Use get_repo to fetch metadata before creating branches. Use create_branch to prepare a feature branch for commits.'). Add dependency hints: 'Requires valid GitHub PAT in environment.'
