Server has 17 tools with basic naming (verb_noun pattern) and descriptions present. However, descriptions are minimal (10-50 chars), parameter descriptions lack detail, and output schemas are not documented. No tool annotations (readOnlyHint/destructiveHint). Error handling exists but is generic. Parameter validation is weak, no enums, ranges, or format constraints visible. Tools like gcloud_set_traffic accept 'revisions' as object without schema definition. No pagination support despite list tools. Follows basic MCP structure but falls short of production quality.

• Expand all tool descriptions to 100-200 chars. Include WHAT it does, WHEN to use it (vs similar tools), and what it returns. Example: 'List Cloud Build builds in the project. Returns build IDs, status, and timestamps. Use this to discover recent builds before calling get_build for details.'
• Document output schemas for all tools. For list_* tools, specify returned fields (e.g., build_id: string, status: enum[SUCCESS|FAILURE|QUEUED], created_time: ISO8601). For get_* tools, list all returned fields.
• Add pagination parameters (limit: 1-100, offset: 0+) to all list_* tools. Cap default results at 20-50 items. Update descriptions to state the limit.
• Add tool annotations: mark gcloud_run_trigger, gcloud_deploy_service, gcloud_set_traffic with destructiveHint=true. Mark all read-only tools with readOnlyHint=true.
• Replace 'revisions' object parameter in gcloud_set_traffic with explicit schema: {type: 'object', properties: {revision_name: {type: 'string'}, traffic_percent: {type: 'integer', minimum: 0, maximum: 100}}, required: ['revision_name', 'traffic_percent']}. Add description: 'Map of revision names to traffic percentages (0-100). Percentages must sum to 100.'
