Worked on the sst/opencode repository to deliver an Agent Access Control Clarification and Permissions Model, focusing on improving governance and access control for agent tooling. The approach involved distinguishing between primary agents and subagents, aligning tool access permissions with specific capabilities to minimize misconfigurations and security risks. Documentation was created and updated using Markdown, emphasizing technical writing and git-based traceability to ensure auditability and support onboarding and compliance needs. The work centered on design clarity rather than bug fixes, providing clear, traceable documentation that supports secure usage and cross-team collaboration within the project’s agent management and permissions framework.
