The Agent Skills Directory

[Methodology and Operational Controls]: The skill defines a rigorous four-phase lifecycle (Prepare, Execute, Validate, Handoff) for development milestones. It incorporates explicit "Gate: STOP" instructions at each phase transition, ensuring that the agent remains under user control and does not perform autonomous actions without verification.
[State Management and Persistence]: Technical state is maintained across sessions through a local .porting/ directory within the project root. While the skill involves reading and writing configuration files (e.g., porting-memory.md), these are used strictly for context preservation and are managed within the local development environment.
[Integrated Development Tools]: The instructions utilize standard system utilities such as git, grep, killall, and lldb. These tools are employed in a manner consistent with software porting and debugging workflows, with guidance provided to avoid destructive operations.
[Collaboration and Escalation]: The skill explicitly instructs the agent to surface uncertainties and visual findings to the user. This collaborative approach, combined with the requirement for user-driven phase transitions, serves as a significant safeguard against unintended behavior.
