Agent readability score

Strengths

• Tool names are action-oriented and indicate purpose (e.g., 'generate_paint_intent' implies strategic execution).
• Descriptions include usage context (e.g., 'use for broad scanning') and warnings (e.g., 'heavy payload').

Weaknesses

• Parameter schemas are not explicitly defined (e.g., 'coordinate' type or 'USDC amount' precision).
• Error handling is inconsistent (e.g., 'generate_paint_intent' checks balance, but 'get_user_balance' lacks failure scenarios).

• get_pixel_info — Lacks explicit parameter definition for 'coordinate' input.
• deposit_usdc — Does not specify required 'USDC amount' parameter format.
• get_user_balance — No mention of handling zero-balance edge cases.

Verdict

Tools are generally well-structured with clear intent and contextual guidance, but missing parameter schemas and inconsistent error handling may hinder agent reliability. The 85/100 score reflects strong clarity with room for improvement in technical specificity.

Event narrative

Server transitioned from 'auth-gated' to 'legacy' era with compliance score rising to 100.

Risk: medium

• 2026-09-10T21:16:35.016Z — era changed from 'auth-gated' to 'legacy' · transition to legacy configuration may indicate reduced security controls
• 2026-09-11T01:59:45.474Z — compliance score improved from null to 100 · full compliance achieved in legacy era

Advice

Monitor legacy era security implications while maintaining 100% compliance. Verify if era transition was intentional and document configuration changes.
