openfasttrace

Support spec-driven development in projects that use OpenFastTrace, a system-requirements document in `doc/system_requirements.md`, an arc42-style design in `doc/design.md`, and per-issue task plans in `doc/changesets/`. Use when AI agent must turn a new GitHub issue or Jira ticket into a changeset plan, update traced requirements and design before or alongside code, and keep all implementation and verification work aligned with the project's quality requirements.

Reverse-engineer missing or incomplete OpenFastTrace system requirements and arc42-style design documentation from a project's user guide, existing documentation, tests, and code. Use when the agent must draft or repair `doc/system_requirements.md`, `doc/design.md`, and `doc/design/` chapters; infer features, requirements, scenarios, and design items; align design coverage with requirements; and report contradictions or open issues found during reverse engineering.
