+## [1.3.0] — 2026-06-16
+
+### Added
+
+**Platform: GitHub Copilot CLI** (4 → 5 supported platforms):
+
+- New `.copilot-plugin/plugin.json` declaring A Team's agents (`../.claude/agents/`)
+ and skills (`../skills/`) for Copilot CLI auto-install.
+- New `.copilot-plugin/hooks/hooks.json` carrying `SessionStart`, `PreToolUse`,
+ `PostToolUse`, and `SessionEnd` hooks — full enforcement parity with Claude Code's
+ `.claude/settings.json` (not just SessionStart like Codex CLI today).
+- Install command: `copilot plugin install RBraga01/a-team:.copilot-plugin`.
+- No new agents, skills, or rules — purely additive platform plumbing.
+
+### Changed
+
+- `README.md`, `CLAUDE.md`, `AGENTS.md`, `CONTRIBUTING.md`, and the PR template
+ updated to reference Copilot CLI as a supported platform.
+- Version bumped to `1.3.0` across all plugin manifests for consistency.

with a lead orchestrator, hard quality gates, and a Pipeline Auditor that verifies work was done,
not just reported. Drop this folder into any project and it's operational from the first keystroke.

Yes. All platforms share the same .agent-sync/ directory (DAILY.md, ROUTING.md, TEAM.md), so orchestrator state is visible regardless of which CLI triggered it.
Important: session-start hooks are not propagated between platforms. Each platform's plugin manifest configures its own onSessionStart hook independently — the files are already pre-configured for Claude Code, Codex, and Cursor.

Yes. A Team is platform-agnostic — it's markdown files and JSON, with no compiled code or OS-specific scripts. The path normalisation for git worktrees uses standard POSIX-style paths that work across all systems via the git CLI.
