- Added sync truncation helpers to recursively prepare session entries and externalize image data.
- Reworked session persistence to use synchronous preparation plus `writeSync` with close-state checks.
- Added synchronous session-storage APIs and rerouted write paths to `writeLineSync`/`readTextSync`.
- Added `BlobStore.putSync`, migrated hashing to `Bun.SHA256`, and updated hash tests accordingly.
/drop works like /new but permanently deletes the current session file
and artifacts instead of flushing (saving) it. Useful when the session
should not be kept.
- add drop?: boolean to NewSessionOptions
- branch in AgentSession.newSession(): skip flush, delete via
FileSessionStorage.deleteSessionWithArtifacts when drop=true;
deletion failure is non-fatal (logged, new session still starts)
- wire handleDropCommand() through InteractiveModeContext interface,
InteractiveMode delegation, and CommandController implementation
- guard: shows error if session has not been saved yet (no file to drop)
- register /drop in builtin-registry adjacent to /new
- Added `onAssistantMessageEvent` callback to Agent API for inspecting and aborting assistant streaming events.
- Added `setAssistantMessageEventInterceptor()` method to dynamically update assistant message event handlers.
- Converted `checkAutoGeneratedFileContent()` from async to synchronous for improved streaming edit abort detection performance.
- Implemented LRU caching in auto-generated file detection with early path-based checks to prevent unnecessary edits.
- Refactored streaming edit pre-caching to use assistant message event interception for real-time abort capability.
- Extracted `peekFile()` utility for efficient file prefix reading with pooled buffer reuse strategy.
- Extracted stream parsing utilities into reusable functions in pi-utils package (readLines, readJsonl, parseJsonlLenient, readSseJson).
- Replaced manual buffer management with ConcatSink class for efficient stream handling across multiple modules.
- Simplified SSE stream parsing in google-gemini-cli provider by using readSseJson utility instead of manual reader setup.
- Refactored MCP stdio transport to use readLines utility for cleaner line-based stream processing.
- Updated RPC client and mode to use readJsonl utility, removing duplicate JSONL parsing logic.
- Optimized buffer allocations by using allocUnsafe where data is immediately populated and reusing empty buffer instances.
- 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.
