v18.1.2

@oh-my-pi/pi-agent-core

Fixed

• Fixed preservation of Claude thinking/reasoning context when conversations are compacted or tool results are pruned.

@oh-my-pi/pi-ai

Added

• Added thinking controls for Amazon Bedrock models.
• Added dynamic mid-conversation updates for Anthropic system prompts, tools, and reasoning effort.
• Added deferred tool loading and prompt caching for Anthropic models.
• Added configurable handling for invalid Anthropic thinking blocks through anthropicPrefixMismatchBehavior.

Fixed

• Fixed compatibility issues with Anthropic thinking and prompt-cache breakpoints across deployments, preserving valid reasoning context while preventing invalid-signature errors.
• Fixed incorrect operating-system information reported in request headers on non-Linux systems.
• Fixed Google Antigravity quota handling so requests rotate to another account with available usage instead of unnecessarily switching models.
• Fixed Anthropic authentication for newer models by updating the Claude Code request fingerprint.

@oh-my-pi/pi-catalog

Added

• Added support for turn-scoped system messages, changing tools during a conversation, and setting effort on individual messages.
• Added support for Claude Fable 5.1 models, with improved thinking-prefix handling across supported Claude models.
• Added DeepSeek V4 Flash Vision Exp, Mercury 2.5 Preview, and Xiaomi MiMo V2.5 Pro UltraSpeed models.

Changed

• Updated model pricing and context-window limits.

@oh-my-pi/pi-coding-agent

Added

• Recover stray SM:EDIT payloads emitted as plain text into real edit tool calls, with support for disabling this behavior through the edit.recoverInlineEdits setting.
• Advisors now receive context from the active memory backend, including project decisions and recalled instructions; advisors also gain the recall tool when supported by the backend.

Changed

• Replaced the sloppy edit format's symbolic markers with a clearer XML-based format using SM:EDIT, SM:FIND, and SM:PUT tags. Edit errors now include copy-ready XML payloads.
• Increased the default input delay for the trace CLI to 3 seconds.

Fixed

• Improved chat history stability in long-running sessions by avoiding unnecessary updates when date or directory context changes.
• Fixed the trace CLI hanging during proxy connections and added support for forward HTTP proxies.
• Fixed newly started sessions using stale model context-window limits after background model discovery completes; the active model now refreshes automatically so context usage and compaction thresholds match the model catalog.

What's Changed

• fix(coding-agent): rebind active model after background discovery by @roboomp in #10491
• fix(mcp): expand Claude plugin stdio env placeholders by @mrexodia in #10481
