Server defines 9 tools with explicit schemas and annotations. Naming follows verb_noun pattern (multisim_*). Descriptions are present but brief (avg 95 chars, below 194-char baseline). All tools have input schemas with type definitions. Critical gaps: parameter descriptions are sparse or missing (e.g., multisim_wire via points lack description; multisim_auto_route direction enum has no description). No output schemas documented. Error handling is minimal, tool responses are opaque JSON from CLI subprocess with no recovery guidance. Tool annotations (readOnlyHint, idempotentHint) are present but inconsistently applied (multisim_launch marked idempotent=true despite side effects). Composition is sound, each tool has one responsibility. Security: CLI subprocess spawning with user-controlled paths (multisim_launch --file, multisim_screenshot --path) lacks path validation, risking directory traversal.

• Add detailed parameter descriptions for all inputs. Example: multisim_auto_route direction should be 'Routing strategy: horizontal-first routes right then down; vertical-first routes down then right. Affects wire aesthetics and overlap avoidance.'
• Document output schemas for all tools. Example: multisim_status should return {window_handle: string, process_id: number, version: string}. multisim_place_component should return {component_id: string, x: integer, y: integer} to enable downstream wiring.
• Validate file paths before passing to CLI. Use path.resolve(baseDir, userPath) and reject paths outside baseDir. Prevents directory traversal attacks.
• Wrap CLI errors with actionable recovery guidance. Parse stderr and exit codes; return structured errors like {error: 'component_not_found', component: 'INVALID_NAME', suggestion: 'Did you mean 74LS00?'}.
• Correct idempotent annotations. multisim_launch should be idempotent=false (launching is a side effect). multisim_new_design should be idempotent=true (creating a blank design is repeatable).
