# Check SDK Updates Compare the versions of `@anthropic-ai/claude-code`, `@anthropic-ai/claude-agent-sdk`, and `@openai/codex-sdk` declared in `package.json` against the latest published version on npm. ## Steps 1. Read the `dependencies` block of `package.json` and extract the current declared range for each of: - `@anthropic-ai/claude-code` - `@anthropic-ai/claude-agent-sdk` - `@openai/codex-sdk` 2. Run the following command (single Bash call) to fetch latest versions in parallel: ```bash npm view @anthropic-ai/claude-code version & \ npm view @anthropic-ai/claude-agent-sdk version & \ npm view @openai/codex-sdk version & \ wait ``` Map the three lines of output back to the three packages in the order requested. 3. For each package, compare the declared version (strip leading `^`/`~`) with the latest. Report a compact table: ``` Package Current Latest Status @anthropic-ai/claude-code 2.1.119 2.1.120 ⬆ update @anthropic-ai/claude-agent-sdk 0.2.119 0.2.119 ✓ up to date @openai/codex-sdk 0.125.0 0.126.0 ⬆ update ``` 4. **For each outdated package, analyze the gap between current and latest** so the user can decide how to implement the update. For each one: a. Get the list of versions in between with: ```bash npm view <pkg> versions --json ``` Filter to versions strictly greater than current and ≤ latest. No...
