Add vetted SDD agent/tool repositories to awesome list

[Copilot]

The issue asked which candidate repositories from a provided list should be included in this awesome list, then requested adding the applicable ones. This PR curates and adds only the entries that are materially aligned with spec-driven development workflows.

• What was added

  • Development Frameworks
    • agent-skills (addyosmani)
    • skills (mattpocock)
    • superpowers
  • Workflow Management
    • taskmaster (claude-task-master)

• What was intentionally not added

  • andrej-karpathy-skills, gstack, and ecc were left out because they are broader agent-operating/guideline ecosystems and not clearly SDD-focused for this list’s scope.

• README delta shape

  • Added new bullet entries with star badges and concise scope descriptions in existing sections (no section reshuffle).

- [taskmaster](https://github.com/eyaltoledano/claude-task-master) ![](https://img.shields.io/github/stars/eyaltoledano/claude-task-master.svg?cacheSeconds=86400) - Task management system for AI-driven development that parses PRDs and orchestrates implementation workflows.
