ECA 0.160.0 Release Notes — What's New

Fix context usage counting only output tokens on anthropic-compatible providers that report input usage in message_delta (e.g. Z.AI). #604
Accept unescaped square brackets, non-ASCII and other reserved chars in workspace file URI paths. #594 #605
Fix inflated costs for OpenAI-compatible providers (e.g. Synthetic); count usage once per request before completion and retain received usage on stream errors.
Tool prompts: push, git config, shell search/read and sub-agents run on explicit request; rule headings are tool-scoped.
Recover Anthropic streaming responses interrupted by transient TLS bad_record_mac failures.
BREAKING: plugins.install now appends across config layers. Set plugins.installMode to replace beside the list to exclude inherited plugins as before.
Add mcpToolSearch config to keep MCP tool schemas out of context until the LLM loads them with the new eca__search_tools tool.
Fix /compact steered while the chat is running: compact with its instructions at the next turn boundary and resume the task, instead of sending it to the LLM as text. #600
Hide GitHub Copilot models the account can't use (model_picker_enabled: false or a disabled policy) instead of listing the whole catalog, and don't fall back to models.dev when none is usable. #601
Pick the GitHub Copilot default model from the account's catalog (versatile, then powerful, then lightweight category) instead of hardcoding gpt-5.5, which some plans don't include.
Fix remote MCP servers whose SSE events omit the space after event: (e.g. Z.AI) hanging on initialize; bump plumcp to 0.2.3. #586
