Upgrade Gemini CLI to v0.54.0 for session-ID rotation on model fallback
v0.54.0 rotates the session ID on model fallback, enforces HTTPS for GoogleCredentialsAuthProvider, filters thought parts when context management is disabled, skips merged function-response turns in the active loop, and tightens file keychain tag validation.
Why this loop
Stateful API errors after model fallback and cleartext credential leakage are fixed in this release. Upgrading picks up session-ID rotation on fallback, HTTPS-only Google credential auth, safer history when context management is off (thought parts filtered), more reliable active-loop detection (merged function-response turns skipped), and explicit tag length/validation in the file keychain. Teams using Gemini CLI with auth, multi-model fallback, or a2a content proposals should move to v0.54.0 so these core fixes apply without workarounds.
Proposed actions
- npm install -g @google/gemini-cli@0.54.0 && gemini --version
- In your Gemini CLI auth/config path, remove any http:// credential or token endpoint overrides so GoogleCredentialsAuthProvider only uses HTTPS endpoints
- Reproduce a model-fallback path once (force a primary-model failure or switch models mid-session) and confirm the CLI rotates the session ID and no longer returns stateful API errors from the prior session
- If context management is disabled in your config, start a fresh session and confirm thought parts no longer appear in history turns used for context
- For a2a-server workflows, re-run getProposedContent on a CRLF-sourced patch and confirm proposed content is normalized to LF before apply

# DevAgentRadar → Google Antigravity Goal: turn this release signal into a safe pilot plan for my stack. ## Context Assistant: Gemini CLI Proposal: Upgrade Gemini CLI to v0.54.0 for session-ID rotation on model fallback Summary: v0.54.0 rotates the session ID on model fallback, enforces HTTPS for GoogleCredentialsAuthProvider, filters thought parts when context management is disabled, skips merged function-response turns in the active loop, and tightens file keychain tag validation.

Flag security / permission implications 3. Keep the pilot reversible
