This is a 28-tool Paystack integration server with mixed quality. Strengths: all tools have non-empty descriptions (10 - 200 chars, within baseline range); input schemas are present with type declarations for most parameters; tool names follow verb_noun pattern consistently. Weaknesses: descriptions are often generic and lack context about WHEN to use a tool or what happens next; parameter descriptions are minimal (many just repeat the name or value type without actionable guidance); output schemas are not documented anywhere in the visible code; error handling is not evident from the tool definitions; several tools accept ambiguous parameter types (string|number) without guidance on which to use; no pagination guidance documented despite list_* tools; no mention of idempotence, retryability, or side effects in tool descriptions. Example: create_product has description 'Create a new product on your Paystack integration', this is 48 chars, acceptable length, but lacks guidance on when to call it vs update_product, what fields are required, or what the response looks like. Example: validate_customer accepts both 'code' and multiple validation parameters but does not explain the relationship between them. Example: list_products accepts page and perPage but does not specify min/max or total count behavior. The server falls into the 'fair but needs work' category with some foundational quality but missing critical LLM-optimization details.

• Document output schemas for all 28 tools. For each tool, publish the JSON structure returned: field names, types, and which fields are IDs/references needed by downstream tools. Example: create_product should document that it returns {product_id, name, price, currency, created_at} so agents can use product_id in follow-up calls.
• Expand tool descriptions from 35 - 50 chars to 100 - 200 chars (baseline 194 chars). Include WHAT the tool does, WHEN to use it (vs similar tools), and prerequisites. Example: 'Create a new customer in Paystack. Use this before initialize_transaction to associate a payment with a customer record. Requires valid email. If email already exists, use update_customer instead.'
• Add min/max constraints to pagination parameters. Example: 'Page number (1 - ∞, default=1)' and 'Items per page (1 - 100, default=20). Response includes total_count and next_cursor for safe iteration.'
• Replace free-form parameter descriptions with formal constraints (enums, patterns, ranges). Example for validate_customer: 'country': {type: 'string', enum: ['NG', 'US', 'ZA', ...], description: 'ISO 3166-1 alpha-2 country code'} and 'type': {type: 'string', enum: ['account_number', 'bvn', 'nuban'], description: 'Validation method'}.
• Add error recovery hints to tool descriptions. Example for get_customer: 'If customer not found by code, try searching by email using search_customers(). Returns HTTP 404 if not found.'
• Explicitly document side effects and idempotence. Add to charge_authorization: 'WARNING: This tool initiates a real financial transaction. Charges are final and non-idempotent, do not retry on network errors without confirming the charge did not go through first.'
