- Added topP, topK, minP, presencePenalty, and repetitionPenalty sampling control options to StreamOptions and AgentOptions interfaces.
- Implemented getter and setter properties on Agent class for runtime configuration of model sampling parameters.
- Added UI configuration and preset value providers for five new sampling parameters in coding-agent settings schema and components.
- Integrated sampling control parameters through proxy layer and agent session configuration for end-to-end provider support.
- Added fallback empty string for undefined tool descriptions across all AI providers to prevent runtime errors.
- Made `description` field required in CustomTool interface and normalized tool descriptions in agent-loop.
- Refactored tool normalization in agent-loop by renaming `injectIntentIntoTools()` to `normalizeTools()` with conditional intent injection.
- Added comprehensive description metadata to todo-write tool schema fields for improved clarity.
Move agent__intent description from per-tool JSON schema injection (repeated
once per tool) into a single conditional block in the system prompt template.
Token savings scale with tool count.
- agent-loop: remove description from intent schema injection
- system-prompt.md: add intentTracing/intentField template block
- sdk: compute intentField once, pass through to prompt builder
- system-prompt.ts: thread intentField option into template context
- Renamed `file` parameter to `path` in edit tool schemas and all test cases for consistency.
- Removed `file` property fallback from EditRenderArgs interface and path resolution methods.
- Refactored browser viewport schema to use snake_case `device_scale_factor` with explicit camelCase mapping for Puppeteer API.
- Added hashline edit rule requiring `end` tag to include closing braces/brackets when replacing blocks.
- Refactored INTENT_FIELD injection logic to conditionally reorder schema properties and update required array.
- Updated tool result messages to include error details when tool execution fails.
- Modified createAbortedToolResult() to accept optional errorMessage parameter for enhanced error reporting.
- Updated package.json files arrays across multiple packages to include CHANGELOG.md and README.md for distribution.
- Expanded natives package description and keywords to document Rust bindings for clipboard, image, PTY, shell, and syntax-highlighting functionality.
- Added sync-exports npm script to root package.json for managing package export synchronization.
- Removed public directory from stats package and README.md from utils package distribution files.
- Added sync-exports.ts script to enforce canonical package.json field ordering and auto-generate exports from filesystem structure.
- Expanded subpath exports across 11 packages (ai, agent, coding-agent, natives, stats, utils, tui, swarm-extension) to enable flexible module imports.
- Reorganized package.json field ordering to follow standard conventions with metadata before main/exports and files/exports at end.
- Consolidated wildcard export patterns to simplify import paths while maintaining backward compatibility with explicit subpath exports.
- Exported `finalizeSubprocessOutput()` function and `SubmitResultItem` interface for subprocess output finalization with submit_result validation.
- Added automatic reminders (up to 3) when subagent stops without calling submit_result tool, aborting with exit code 1 after final reminder.
- Extracted subprocess output finalization logic into dedicated `finalizeSubprocessOutput()` function for improved testability and reusability.
- Added comprehensive test coverage for subagent warning injection, reminder behavior, and abort handling in executor module.
- Changed hashline format separator from pipe (|) to colon (:) for improved readability across all tools and output formats.
- Refactored hashline edit API with operation-based structure: renamed delete->rm, rename->mv, set->target/new_content, and added explicit op field for operation types.
- Updated hashline hash encoding from 4-character base36 to 2-character hexadecimal for more compact representation.
- Replaced anchor terminology with tags throughout hashline documentation and API for clearer semantics.
- Added streamed tool intent display in working message to show real-time intent tracking during agent execution.
- Changed intent tracing field name from `$intent` to `_intent` across tool schemas and agent core for consistency.
- Added support for file deletion and renaming operations in hashline edit mode.
- Renamed hashline edit operation fields: `set` to `target`/`new_content`, `set_range` to `first`/`last`/`new_content`, `insert` to `inserted_lines`.
- Added optional `intent` field to `ToolCall` interface for capturing harness-level intent metadata.
- Added `intentTracing` configuration option to enable intent goal extraction from tool calls with automatic `$intent` field injection and argument stripping.
- Implemented intent injection and extraction logic in agent-loop to populate tool call intent metadata when intentTracing is enabled.
- Added `tools.intentTracing` setting to coding-agent configuration schema with environment variable override support.
