Subscribr CLI exposes 38 tools with minimal schema and description quality. Most tools have descriptions under 50 chars (well below the 194-char baseline for A+ tools). Input schemas are present but extremely sparse: 28 tools have empty object schemas ({}), and only 10 tools declare any parameters at all. No parameter descriptions are visible in the schema definitions. Output schemas are completely undocumented. Error handling and recovery guidance are absent. The tool naming follows verb_noun convention (get_, list_, create_, update_, remove_) which is good, but descriptions lack actionable context about when to use each tool, what it returns, or dependencies between tools.

• Expand all tool descriptions to 100-200 characters. Include: (1) what the tool does, (2) when to use it vs similar tools, (3) what it returns. Example: 'Get the authenticated team's information including name, plan tier, and member count. Call this first to verify API access and determine available features.'
• Add complete input schemas for all 28 tools with empty schemas. For list_* tools, add pagination params (limit, offset/cursor) with ranges (e.g., limit 1-100). For get_* tools, add required ID params with descriptions (e.g., 'project_id: string, the unique project identifier').
• Document output schemas for all tools. Specify returned fields, types, and whether results are paginated. Example: 'Returns {project_id: string, name: string, status: enum[draft|active|archived], created_at: ISO8601, total_items: number}'.
• Add parameter descriptions to all 10 tools with parameters. Describe what each parameter controls, valid ranges, and format constraints. Example: 'operation_id: string, the unique operation identifier returned by start-script-agent-run. Required to poll status.'
• Implement error handling guidance. Document common errors (e.g., 'operation_id not found', 'insufficient credits') and recovery steps. Example: 'If operation_id not found, call list-projects to find valid project IDs, then retry.'
