- Added `listWorkspace` native binding and API types, exporting bounded workspace trees with AGENTS.md candidates.
- Reworked `buildWorkspaceTree` and `buildDirectoryTree` to call `listWorkspace` with 5s timeout defaults.
- Replaced startup AGENTS.md discovery with workspace-tree-only scanning and removed legacy AgentsMdSearch session plumbing.
- Updated `WorkspaceTree` and system prompt context to expose `agentsMdFiles` and aligned tests/changelog expectations.
- BuildWorkspaceTree now attempts to list files via `git ls-files` and builds a child index for tree rendering, avoiding native recursion when git output is available.
- `buildDirectoryTree` gained an optional `childIndex` path map, `tryListGitFiles` now applies a 3s timeout and falls back to existing native scan on failure or timeout.
- Added a workspace-tree test that verifies git-backed listing skips gitignored entries while including tracked workspace files.
- Refactored directory tree child discovery into a dedicated direct-name helper.
- Used fs.readdir for non-gitignore directories instead of globbing.
- Kept child-name filtering for excluded and hidden entries in the same selection flow.
- Added DirectoryTree, DirectoryTreeOptions, and buildDirectoryTree exports for configurable tree rendering.
- Changed read tool directory output to use buildDirectoryTree with depth and exclusion limits.
- Added read.summarize settings and summary-mode parseable read output behavior when no selector is used.
- Added tests for truncated root/child listings and hidden or excluded entry filtering.
- Added `WorkspaceTree` and `buildWorkspaceTree` APIs for working-directory tree rendering with limits.
- Extended `buildSystemPrompt` and `createAgentSession` to resolve and pass workspace tree context for system prompts.
- Updated the system prompt template to include a `<workspace-tree>` section with truncation notices before append output.
- Added workspace-tree and system-prompt tests covering sorting, truncation, exclusions, and prompt ordering.
