v1.83.0

This release adds an opt-in sudo askpass flow for shell commands, a headless embedded chat session API, and several bug fixes for cost accounting, session handling, and custom provider model resolution.

What's New

• Adds opt-in sudo_askpass: true flag to the shell toolset, bridging sudo password prompts to the agent's elicitation flow instead of hanging until timeout
• Adds pkg/embeddedchat, a headless chat session API for embedding docker-agent runtime conversations in non-docker-agent UIs, with support for streaming events, tool call confirmation, conversation restart, and cancellation
• Makes OpenAI, Anthropic, Google, and Amazon Bedrock providers optional via build tags, allowing embedders to drop unneeded providers and reduce binary size

Improvements

• Replaces the bleve full-text search library with a lightweight pure-Go BM25 matcher for model routing, removing a large transitive dependency tree and enabling WebAssembly cross-compilation

Bug Fixes

• Fixes duplicate tool_result blocks for the same tool_call_id being passed to strict providers such as AWS Bedrock
• Fixes custom providers (defined with base_url + token_key) triggering a blocking fetch of the full models.dev catalog (~3.4 MB) on every turn in internet-restricted environments
• Fixes reasoning tokens from streaming usage not being recorded for Anthropic extended-thinking models
• Fixes run_background_agent sub-sessions not being persisted to the store
• Adds a warning when an uncatalogued model bills $0 with token usage
• Fixes the Shift+Tab thinking-level cycle in the TUI not offering the max effort tier on Claude models that support it (Opus 4.7/4.8, Sonnet 4.6, Fable 5)

Technical Changes

• Replaces external go-memoize and go-cache libraries with a new internal pkg/memoize package built on golang.org/x/sync/singleflight
• Makes the RAG toolset opt-in to remove the cgo dependency on go-tree-sitter from the default build
• Documents YAML anchors, aliases, and merge keys support in the configuration overview
• Documents the 10-second per-toolset tool-listing timeout for wedged MCP servers in the troubleshooting guide
