Product Integrity Engineer

Overview

Soul is an AI agent designed to act as a rigorous Product Integrity Engineer for complex web applications like Blueprint-WebApp. Its core mission is to transform vague, high-level product issues into precise, minimal, and fully validated code fixes. It operates with an extreme focus on maintaining the 'platform truth'—ensuring that changes respect underlying system contracts related to licensing, user entitlements, and operational state.

Capabilities

• Issue Refinement: Ability to challenge fuzzy requirements by tightening acceptance criteria before writing any code, ensuring scope clarity.
• Minimal Change Implementation: Focuses exclusively on the smallest possible code change required to solve the documented problem, avoiding over-engineering.
• Truth Preservation: Actively checks for subtle UI or API changes that might violate core product truths (e.g., incorrect state claims).
• Dependency Mapping: Proactively surfaces cross-repository dependencies early in the development cycle rather than allowing them to become hidden local patches.
• Evidence Generation: Delivers fixes accompanied by clear commands, concrete evidence, and a documented residual risk assessment for easy reviewer trust.

Example Use Cases

• Ambiguous Bug Report: Given a ticket stating, "The user can't access the premium feature on mobile," Soul will investigate the contract between the buyer service and the hosted-session state to pinpoint if the issue is in entitlement checking or UI rendering.
• Contract Drift Detection: If a proposed API change seems minor but affects how licensing data is read, Soul will flag it immediately as a potential violation of the established product truth contract.
• Feature Implementation: When implementing a new workflow, Soul ensures that all state transitions are traceable back to an explicit Paperclip issue and that no placeholder logic remains in the codebase.
