Critical gaps across naming, descriptions, and schemas. Tool names lack consistent verb prefixes (health, getTabs, snapshot lack action clarity). Descriptions are present but minimal (10-50 chars for most tools), providing insufficient context for LLM selection. Input schemas exist but lack depth: most parameters have only type and description, no enums for constrained inputs (e.g., 'direction' in scroll, 'format' in cloak-fetch). Output schemas are entirely undocumented. Error handling guidance is absent. The cloak-fetch tool has rich parameter documentation but stands alone; 18 other tools are under-specified. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk classifications. Parameter descriptions are generic ('Tab identifier', 'URL to navigate to') without format constraints or examples. No pagination guidance for tools returning lists.

• Rename tools to start with action verbs: 'health' → 'check_health', 'getTabs' → 'list_tabs', 'snapshot' → 'get_snapshot', 'screenshotRaw' → 'take_screenshot'. Follow verb_noun convention consistently.
• Expand all descriptions to 50-200 chars. Include WHAT the tool does, WHEN to use it, and any prerequisites. E.g., 'Check Camofox browser health status' → 'Check if the Camofox browser is running and responsive. Call this before other operations to verify the browser is ready. Returns health status and any error details.'
• Document output schemas for all tools. Specify field names, types, and structure. E.g., getTabs should return {tabs: [{id: string, url: string, title: string}], total: number}. This enables LLMs to chain calls and extract required IDs.
• Add tool annotations to all tools. Use readOnlyHint: true for read-only tools (health, getTabs, snapshot, extract, wait, screenshotRaw, readability, cloak-fetch, detectChallenge). Use destructiveHint: true for write tools (start, stop, createTab, closeTab, evaluate, click, type, scroll, navigate, destroySession).
• Add enums and format constraints to parameters. E.g., scroll direction: enum ['up', 'down', 'left', 'right']. Element ref format: 'CSS selector or accessibility tree reference'. Timeout: number (1-60000 ms). This prevents invalid LLM inputs and reduces errors.
