 | Team Assign | Assign tasks.md items to human engineers, split into subtasks, and generate a per-engineer workboard | `process` | Read+Write | [spec-kit-team-assign](https://github.com/tarunkumarbhati/spec-kit-team-assign) |
 | Test Coverage Drift Control | Generate incremental coverage drift reports and planned remediation tasks after implementation | `code` | Read+Write | [spec-kit-test-coverage-drift-control](https://github.com/benizzio/spec-kit-test-coverage-drift-control) |
+| ThreatSpec | STRIDE and AI/ML threat modeling with threat-to-test traceability and security convergence | `process` | Read+Write | [spec-kit-threatspec](https://github.com/hupe1980/spec-kit-threatspec) |
 | Time Machine | Retroactively apply the full SDD workflow to existing codebases — analyse, spec, and ship feature-by-feature | `process` | Read+Write | [spec-kit-time-machine](https://github.com/teeyo/spec-kit-time-machine) |
 | TinySpec | Lightweight single-file workflow for small tasks — skip the heavy multi-step SDD process | `process` | Read+Write | [spec-kit-tinyspec](https://github.com/Quratulain-bilal/spec-kit-tinyspec) |
