- Restructured system prompt with coordinator-specific guidance for parallel task delegation.
- Extracted process management utilities from coding-agent shell module into dedicated procmgr module in utils package.
- Migrated shell configuration retrieval to SettingsManager class with new getGlobalShellConfig() static method.
- Replaced custom killProcessTree() implementation with new terminate() function supporting graceful shutdown with timeout and AbortSignal.
- Updated ptree.ChildProcess to use generic type parameter for input stream masking and delegated process termination to procmgr.terminate().
- Centralized process management across coding-agent modules to use SettingsManager and procmgr utilities instead of standalone shell functions.
- Simplified ptree API by removing spawnGroup and spawnAttached variants, consolidating into single spawn function.
- Replaced AsyncQueue class with simpler pushStream utility function for stream management.
- Refactored ChildProcess class to use AbortController instead of callback-based signal handling.
- Renamed captureText method to wait and execText function to exec for clearer API semantics.
- Removed mode parameter from exec function, eliminating distinction between spawn modes.
- Updated all call sites across coding-agent to use simplified ptree API.
- Added ToolChoice type and toolChoice parameter support across all AI providers (OpenAI, Azure OpenAI, Anthropic, Google) enabling fine-grained control over tool/function selection during LLM calls.
- Added toolChoice override capability to Agent.prompt() method and session prompt options allowing callers to control tool selection behavior per request.
- Added provider-specific tool choice mapping functions (mapAnthropicToolChoice, mapGoogleToolChoice, mapOpenAiToolChoice) to normalize tool choice formats across different LLM APIs.
- Removed kernel heartbeat/ping mechanism from PythonKernel, simplifying health monitoring by relying on direct isAlive() checks instead of periodic HTTP requests.
- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome.
- Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'.
- Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock.
- Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters.
- Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.
- Fixed autocomplete race condition in editor by tracking request ID to discard stale results.
- Added guard clause in plugin-settings to prevent null reference when settings list is undefined.
- Added branch change callbacks in footer to update state after git head resolution.
- Added timing instrumentation to Python kernel startup and gateway acquisition.
- Improved error logging in settings manager for config file access failures.
- Fixed model discovery to re-check file existence after JSON to YAML migration and improved file access error handling.
- Converted readdirSync, readFileSync, and statSync to async readdir, readFile, stat across skills and agent discovery.
- Made scanDirectoryForSkills async and refactored custom directory scanning to use Promise.all for concurrent processing.
- Updated agent discovery to use fs/promises for async file reading and refactored helper patterns.
- Added AgentParsingError exception class for better error handling during agent parsing.
- Added filesystem error type guards (isEnoent, isEacces, isPerm, etc.) to pi-utils for safe error checking.
