 | Spec Kit Figma | Grounds SpecKit spec/plan/tasks in Figma design context via REST or MCP, on macOS/Linux/Windows. | `integration` | Read+Write | [spec-kit-figma](https://github.com/Fyloss/spec-kit-figma) |
 | Spec Kit Memory | Recalls prior specs and decisions from configurable memory tools (e.g. memsearch) before SDLC stages, so planning and specification start from what the project already knows | `docs` | Read+Write | [spec-kit-memory](https://github.com/zaytsevand/spec-kit-memory) |
 | Spec Kit Preview | Generate evidence-backed low, mid, or high fidelity previews from Spec Kit artifacts as Markdown or self-contained HTML | `docs` | Read+Write | [spec-kit-preview](https://github.com/bigsmartben/spec-kit-preview) |
-| Spec Kit Schedule | Optimal multi-agent task scheduling via CP-SAT — DAG precedence, hallucination-aware caps, file-conflict avoidance, stochastic durations, replanning, and interactive HTML output | `process` | Read+Write | [spec-kit-schedule](https://github.com/jfranc38/spec-kit-schedule) |
+| Spec Kit Schedule — parallel subagent rounds | Zero-config planner that turns tasks.md into optimal parallel rounds for subagents (CP-SAT, critical-path aware, file-conflict safe) and an implement command that runs them round by round with tasks.md checkboxes as the single source of progress. | `process` | Read+Write | [spec-kit-schedule](https://github.com/jfranc38/spec-kit-schedule) |
 | Spec Kit TLDR | Render a feature's spec.md / plan.md into a review-oriented TLDR (self-contained HTML dashboard + PR-native Markdown) that surfaces risks for faster PR review. | `visibility` | Read+Write | [speckit-tldr](https://github.com/qurore/speckit-tldr) |
 | Spec Orchestrator | Cross-feature orchestration — track state, select tasks, and detect conflicts across parallel specs | `process` | Read-only | [spec-kit-orchestrator](https://github.com/Quratulain-bilal/spec-kit-orchestrator) |
 | Spec Reference Loader | Reads the ## References section from the feature spec and loads only the listed docs into context | `docs` | Read-only | [spec-kit-spec-reference-loader](https://github.com/KevinBrown5280/spec-kit-spec-reference-loader) |
