v0.4.0

LocalAgent v0.4.0 Release Notes

Release date: 2026-03-03

Highlights

• Completed Tool Call Accuracy delivery through PR12 with stricter runtime/tool contracts and deterministic behaviors.
• Added native glob and grep builtins for safe, non-shell file discovery/search workflows.
• Improved shell-call robustness with better compatibility handling and one-shot auto-repair for common program not found failures.
• Upgraded TUI runtime flow with improved approvals behavior and a dedicated Reasoning side pane (Ctrl+4).
• Added a dedicated manual TUI testing pack and archived historical planning/spec docs for cleaner ongoing documentation.

Included Changes

Tool Runtime and Contract Accuracy (PR2-PR12)

• Added tool-call repair gating and repeat-loop guardrails.
• Added runtime record persistence and versioned runtime tool contract prompting.
• Added deterministic tool-call-accuracy CI harness.
• Normalized provider sampling/controls (temperature, top_p, max_tokens, and seed handling).
• Implemented agent-mode build/plan runtime semantics.
• Implemented JSON run-output event projection mode.

New Builtin Tools and Safe Defaults

• Added glob builtin with scoped path behavior and deterministic match handling.
• Added grep builtin with bounded, deterministic text-search behavior.
• Enabled safer default trust policy posture for tool execution.

Shell and Approval Flow Improvements

• Improved shell tool compatibility and error classification for clearer fallback behavior.
• Added one-shot shell auto-repair for command-not-found style failures.
• Improved approvals UX with auto-refresh behavior, pending indicators, and auto-open refinements.

TUI UX

• Added a dedicated right-side Reasoning pane for live/last-run model reasoning visibility.
• Added global Ctrl+4 pane toggle handling (including terminal control-character fallback).
• Reasoning pane is hidden on banner and auto-shows after first prompt submission.

Documentation and Testing Assets

• Added PR8-PR12 spec docs and a manual TUI testing pack.
• Archived historical tool-call accuracy specs (PR2-PR12) under docs/archive/.
• Aligned docs index and references after archive/reorg.

Compatibility Notes

• glob/grep are additive builtins and do not remove existing tooling paths.
• Tool-call runtime behavior is stricter/more deterministic; integrations should continue ignoring unknown JSON fields for forward compatibility.
• Shell execution behavior may differ by trust mode and environment policy; blocked or unavailable shell runs now provide clearer error semantics.
