This server has severe definition quality gaps. Tool descriptions are present but generic (avg ~80 chars, well below the 194-char baseline). Input schemas are partially defined but lack rigor: many parameters missing type constraints, enums, or validation guidance. No output schemas documented. Error handling is absent, tools fail silently or with generic messages. The LinkedIn queue tools (check_queue, load_queue, save_queue, etc.) are tightly coupled and lack clear composition boundaries. install_skill and load_skills_manifest have reasonable structure but insufficient parameter validation guidance. No tool declares permissions, audit trails, or recovery paths for destructive operations (remove_post, mark_posted). Security concerns: fix_quarantine and install_skill perform filesystem operations without input sanitization or permission gates.

• Document output schemas for all tools. E.g., check_queue should return {posts: [{id, content, scheduled_time, status}], total_count}. Include all fields downstream tools need.
• Add confirmation/dry-run support to destructive tools (remove_post, mark_posted). Return a confirmation_token that must be passed to execute, or add a dry_run=true parameter that returns what would happen without side effects.
• Validate and sanitize all filesystem paths in install_skill and fix_quarantine. Reject paths containing '..', absolute paths outside home directory, and symlinks to untrusted locations. Document these constraints in parameter descriptions.
• Split tightly coupled LinkedIn queue tools. Clarify which tools return post_id, queue state, and timestamps. Add explicit chaining guidance: 'Call load_queue first to get post IDs, then pass post_id to mark_posted.'
• Add enum constraints and format guidance to parameters. E.g., post_id: 'UUID format (e.g., 550e8400-e29b-41d4-a716-446655440000)', link: 'boolean (true=symlink, false=copy)', target_dir: 'absolute path to existing directory'.
