- Replaced SettingsManager class with new Settings singleton providing synchronous get/set API and background persistence.
- Introduced settings-schema.ts as single source of truth for all configuration definitions with 100+ settings organized into logical groups.
- Migrated from method-based settings access (getTheme(), setTheme()) to path-based access using dot notation (settings.get('theme'), settings.set('theme', value)).
- Removed 2035-line settings-manager.ts file and replaced with modular settings.ts (693 lines) and settings-schema.ts (836 lines) for improved maintainability.
- Unified settings schema into single source of truth eliminating duplicate definitions across settings-defs.ts and settings-manager.ts.
- Implemented caching in table and cell results renderers to avoid redundant recalculations when width or cell data hasn't changed.
- Added cache invalidation logic to clear cached render results when cell data or spinner state changes.

- Added `context` as optional alias for the `c` parameter in grep.
- Made hidden files inclusion configurable in find with `hidden` parameter.

- Updated plan mode documentation for self-contained plan files.
- 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.
- 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.
- Added color manipulation utilities to pi-utils for accessibility features.
- Added color-blind mode setting to settings manager.
- Migrated plugins, settings, and config modules from sync to async file operations.
- Updated error handling to use new pi-utils type guards for type-safe checking.
- Removed WASM generation script; use Bun `wasm?raw` loader for imports.
- Added bunfig.toml with loaders for `.md`, `.py`, and `.wasm?raw` text imports.
- Added types/assets/index.d.ts for global TypeScript module declarations.
- Unified TypeScript configuration with tsgo-based checking across monorepo.
- Removed build and WASM steps from install and publish pipelines.
- Added tsconfig.publish.json files to all packages with optimized publish-time configuration.
- Updated all package.json scripts with prepublishOnly hooks for correct type checking during publish.
- Added @oh-my-pi/omp-stats path mappings to root tsconfig.json for consistent imports.
- Added WASM generation script for photon module and integrated into install:dev script.
- Fixed indentation and line breaks in nested code blocks (lsp/render.ts, patch/shared.ts).
- Collapsed overlong function arguments and ternary expressions to standard line length.
- Reorganized import statements for consistency (ask.ts).
- Improved readability of conditional expressions (output-block.ts, web/search/render.ts, python.ts).
- Output block border color now reflects state (error, success, warning) for visual feedback.
- Tools use renderStatusLine, renderTreeList, renderFileList, renderCodeCell for unified formatting.
- Write tool shows streaming preview of content being written with syntax highlighting.
- Read tool displays resolved path information when reading from URLs or symlinks.
- Calculator shows expression and output (e.g., `2+2 = 4`) instead of just the result.
- Empty and error states render consistently with status headers across Find, Grep, Ls, Notebook, Ask.
- Created new TUI component library with renderStatusLine, renderOutputBlock, renderCodeCell, renderFileList, and renderTreeList utilities for consistent tool output rendering.
- Refactored 13+ tools to use centralized TUI components, replacing inline theme formatting and ToolUIKit class usage with declarative component APIs.
- Moved tree rendering utilities (getTreeBranch, getTreeContinuePrefix) from tool render-utils to TUI module for improved code organization.
- Streamlined render function return types across tools from Text to Component objects with render/invalidate methods for better state management.
