Each prompt walks Copilot through a specific ECC workflow (plan → TDD → review → ship). + +The **`.vscode/settings.json`** adds per-task instruction overlays so Copilot receives the right context depending on whether you are generating code, writing tests, reviewing a selection, or drafting a commit message. + +### Feature Coverage + +| ECC Feature | Copilot equivalent | +|-------------|-------------------| +| Coding standards | Always-on via `copilot-instructions.md` | +| Security checklist | Always-on + `security-review` prompt | +| Testing / TDD | Always-on + `tdd` prompt | +| Implementation planning | `plan` prompt | +| Code review | `code-review` prompt | +| Build error resolution | `build-fix` prompt | +| Refactoring | `refactor` prompt | +| Commit message format | Per-task instruction in `settings.json` | +| Hooks / automation | Not supported (Copilot has no hook system) | +| Agents / delegation | Not supported (Copilot has no subagent API) | + +### Limitations + +GitHub Copilot does not have a hook system or a subagent API, so ECC's hook automations (auto-format, TypeScript check, session persistence, dev-server guard) and agent delegation are unavailable. The instruction and prompt layer still brings the full ECC coding philosophy — standards, security, TDD, and workflow — into every Copilot Chat session. + +--- + ## Cross-Tool Feature Parity ECC is the **first plugin to maximize every major AI coding tool**.
