| # OpenCode AI Agent - Maximum Security Configuration | |
| # | |
| # This workflow enables AI-powered issue resolution with strict security controls. | |
| # See: .agents/tools/git/opencode-github-security.md for full documentation | |
| # | |
| # Security features: | |
| # - Trusted users only (OWNER, MEMBER, COLLABORATOR) | |
| # - Requires 'ai-approved' label on issues | |
| # - Rate limiting via concurrency controls | |
| # - Audit logging of all AI actions | |
| # - No access to secrets beyond API key | |
| # - Mandatory human review before merge | |
