v0.1.63

pip install claude-agent-sdk==0.1.63

v0.1.62

New Features

• Top-level skills option: Added skills parameter to ClaudeAgentOptions for enabling skills on the main session without manually configuring allowed_tools and setting_sources. Supports "all" for every discovered skill, a list of named skills, or [] to suppress all skills (#804)

Internal/Other Changes

• Updated bundled Claude CLI to version 2.1.113

v0.1.61

Internal/Other Changes

PyPI: https://pypi.org/project/claude-agent-sdk/0.1.61/

pip install claude-agent-sdk==0.1.61

v0.1.60

New Features

• Subagent transcript helpers: Added list_subagents() and get_subagent_messages() session helpers for reading subagent transcripts, enabling inspection of subagent message chains spawned during a session (#825)
• Distributed tracing: Propagate W3C trace context (TRACEPARENT/TRACESTATE) to the CLI subprocess when an OpenTelemetry span is active, connecting SDK and CLI traces end-to-end. Install with pip install claude-agent-sdk[otel] for optional OpenTelemetry support (#821)
• Cascading session deletion: delete_session() now removes the sibling subagent transcript directory alongside the session file, matching TypeScript SDK behavior (#805)

Bug Fixes

• Empty setting sources: Fixed setting_sources=[] being silently dropped (treated as falsy), which caused the CLI to load default settings instead of disabling all filesystem settings. An empty list now correctly passes --setting-sources= to disable all sources (#822)

Internal/Other Changes

• Updated bundled Claude CLI to version 2.1.111

v0.1.57

New Features

• Cross-user prompt caching: Added exclude_dynamic_sections option to SystemPromptPreset, enabling cross-user prompt cache hits by moving per-user dynamic sections (working directory, memory, git status) out of the system prompt (#797)
• Auto permission mode: Added "auto" to the PermissionMode type, bringing parity with the TypeScript SDK and CLI v2.1.90+ (#785)

Bug Fixes

• Thinking configuration: Fixed thinking={"type": "adaptive"} incorrectly mapping to --max-thinking-tokens 32000 instead of --thinking adaptive. The disabled type similarly now uses --thinking disabled instead of --max-thinking-tokens 0, matching the TypeScript SDK behavior (#796)
