[ca] CLI Updates: Copilot SDK 1.0.2→1.0.3, Gemini CLI 0.39.1→0.47.0 #40748

Overview

Daily CLI version check found 2 updates. Both applied to pkg/constants/version_constants.go and lock files regenerated via two make recompile passes (249/249 compiled, 0 errors).

All other monitored tools already at latest: Claude Code 2.1.185, Copilot CLI 1.0.63, Codex 0.141.0, Pi 0.79.9, GitHub MCP Server v1.4.0, MCP Gateway v0.3.27, Playwright MCP 0.0.76, Playwright CLI 0.1.14, Playwright Browser v1.61.0.

Update Copilot SDK

• Previous: 1.0.2 → New: 1.0.3
• Released: 2026-06-22 (4 days after 1.0.2)
• Package: TypeScript SDK for programmatic control of GitHub Copilot CLI via JSON-RPC

Patch release. Used as DefaultCopilotSDKVersion for the Copilot headless SDK sidecar (copilot-sdk: true).

Impact Assessment

• Risk: Low (patch bump, paired with already-current Copilot CLI 1.0.63)

Package Links

• NPM Package: https://www.npmjs.com/package/`@github/copilot-sdk`
• Repository: https://github.com/github/copilot-sdk

Update Gemini CLI

• Previous: 0.39.1 (2026-04-24) → New: 0.47.0 (2026-06-18)
• Timeline: 8 stable minor releases over ~8 weeks
• Intermediate stable versions: 0.40.0, 0.40.1, 0.41.0–0.41.2, 0.42.0, 0.43.0, 0.44.0, 0.44.1, 0.45.0–0.45.3, 0.46.0, 0.47.0

Key Features / Changes (from v0.47.0 release notes)

• Backend definitions respected for 3.5 flash; auto mode uses 3.5 flash when flag enabled (Respect backend definitions for 3.5 flash and Update auto mode to use 3.5 flash when the flag is enabled. google-gemini/gemini-cli#27645)
• Policy: EBUSY fallback and TOML parse recovery (fix(policy): add EBUSY fallback and TOML parse recovery (#19919) google-gemini/gemini-cli#21541)
• Core: atomic update in MCP tool discovery (fix(core): implement atomic update in MCP tool discovery google-gemini/gemini-cli#27619)
• Vertex AI model mapping fix (Vertex ai model mapping fix google-gemini/gemini-cli#27749)
• Antigravity CLI migration commands + docs (Add documentation and migration commands for Antigravity CLI google-gemini/gemini-cli#27765)
• Avoid persisting empty resume sessions (Avoid persisting empty resume sessions google-gemini/gemini-cli#27770)

Impact Assessment

• Risk: Medium — large multi-version jump (8 minor releases). Gemini is a supported engine in gh-aw; lock files regenerated cleanly with no compile errors. The Antigravity transition messaging is worth monitoring since gh-aw also pins a separate Antigravity CLI version.

Recommendations

• Update priority: Normal. Patch (SDK) is low-risk; Gemini jump is large but compiled cleanly across all 249 workflows.
• Validate a Gemini-engine workflow end-to-end before relying on the new default.
