[a5c-ai]

Upstream version update: Claude Agent SDK TypeScript

• Previous graph version: 0.3.199
• Latest upstream version: 0.3.201
• Package checked: @anthropic-ai/claude-agent-sdk
• Install method/package: unchanged for SDK consumers, npm install @anthropic-ai/claude-agent-sdk@0.3.201 or equivalent yarn/pnpm/bun commands

Sources read:

• Release notes: https://github.com/anthropics/claude-agent-sdk-typescript/releases/tag/v0.3.201
• npm latest check: npm view @anthropic-ai/claude-agent-sdk@latest version returned 0.3.201

Research summary:
The SDK v0.3.201 release notes state that it was updated to parity with Claude Code v2.1.201 and provide versioned npm/yarn/pnpm/bun install commands. The relevant upstream behavior inherited from Claude Code v2.1.201 is that Claude Sonnet 5 sessions no longer use mid-conversation system-role harness reminders.

Likely system impact:

• SDK adapter prompt/harness integration should align with the Claude Code 2.1.201 reminder-role behavior.
• No SDK transport/API breaking change was called out beyond parity.
• Package name and install method remain unchanged.

Migration notes:
The release notes mention upgrading to @anthropic-ai/claude-agent-sdk@0.3.201 via npm/yarn/pnpm/bun.

Assimilation checklist:

• Update Claude Agent SDK AgentVersion to note Claude Code v2.1.201 parity.
• Verify SDK prompt adapter assumptions around Sonnet 5 harness reminders and system-role messages.
• Leave package and install metadata unchanged except for the version number.
