Cloud Browser MCP defines 14 tools with complete input schemas and descriptions. Naming follows verb_noun convention (browser_*). However, descriptions are inconsistent in depth, some are terse (browser_list_tabs: 47 chars) while others are detailed (browser_observe: 120+ chars). Parameter descriptions are present but often lack constraint details (e.g., max_chars range 256-100000 is documented, but many enum values lack explanation). Output schemas are not documented in the source. Error handling exists (BrowserError class) but recovery guidance is minimal. Security patterns (lease_id, confirmation_token) are present but not explained in tool descriptions. Tool composition is sound, each tool has a single responsibility and output IDs chain to downstream tools.

• Document output schemas for all tools. For browser_observe, specify: {rendered_text: string, elements: [{selector: string, text: string, ...}], image?: {data: string, format: string}, cursor: string, revision: integer}. For browser_status, specify: {sessions: [{id: string, tabs: integer, memory_mb: number, ...}], total_memory_mb: number}.
• Expand parameter descriptions for complex objects. For browser_act.action, document: {type: 'click'|'type'|'scroll'|..., selector?: string, text?: string, ...}. For browser_configure.configuration, document: {viewport?: {width: number, height: number}, capture_mode?: 'text'|'visual'|'semantic', ...}.
• Add recovery guidance to error responses. When browser_page_tools fails with UNSUPPORTED_OPERATION, return: 'This Chromium does not expose WebMCP. Try browser_act with manual selectors instead.' When browser_observe times out, suggest: 'Page may be loading. Call browser_wait with a condition before retrying.'
• Clarify security parameters in descriptions. For lease_id, add: 'Optional lease identifier for resource cleanup. Obtained from browser_open response.' For confirmation_token, add: 'Required for destructive actions when approval is enabled. Obtained from a prior browser_act response with approval_required=true.'
• Standardize description length to 80 - 150 characters. Expand browser_list_tabs from 'List existing tabs without selecting or refreshing them' to 'List all open tabs in a session with their IDs and URLs. Does not change focus or reload. Use before browser_act to verify target tab exists.'
