adapter-development — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited adapter-development (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

AIDB debug adapters provide language-agnostic debugging capabilities through the Debug Adapter Protocol (DAP). The architecture is component-based - adapters delegate to specialized components rather than implementing everything in monolithic classes.
For comprehensive architecture details, see docs/developer-guide/overview.md for the complete system architecture and data flow diagrams.
