summary
Claude Code stable release with no user-facing changes in 2.1.159; recent 2.1.x line added Opus 4.8 workflows, local skills plugins, agent dispatch metadata, and auto mode provider coverage.
assimilationNotes
- 2.1.159 itself is documented as internal infrastructure improvements with no user-facing changes.
- Recent 2.1.x releases added dynamic workflows surfaced by /workflows; workflow/session orchestration metadata should be watched by launch and session mappers.
- Plugins in .claude/skills are automatically loaded and `claude plugin init <name>` scaffolds a local plugin, affecting plugin discovery assumptions.
- `claude agents` now honors the `agent` field in settings.json and adds `--agent <name>` override behavior for dispatched sessions.
- `tool_decision` telemetry events include `tool_parameters` when OTEL_LOG_TOOL_DETAILS=1, exposing bash commands and MCP/skill names for observability mapping.
- Auto mode is available on Bedrock, Vertex, and Foundry for Opus 4.7 and Opus 4.8 behind CLAUDE_CODE_ENABLE_AUTO_MODE=1.
- No package rename, install method change, or migration step was published for 2.1.159; installation remains npm install -g @anthropic-ai/claude-code.
releaseHighlights
- Internal infrastructure improvements in v2.1.159.
- Recent v2.1.x: Opus 4.8, dynamic workflows, .claude/skills plugin loading, plugin init, settings.json agent dispatch, telemetry tool_parameters, and auto mode provider support.

Local .claude/skills plugin auto-loading means plugin discovery should not require marketplace installation.
