Changelog

All notable changes to LocalCode will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

3.1.0 - 2026-03-16

Added

  • Persistent input history — last 200 entries saved to ~/.localcode/history.json; survives restarts and is navigable with arrow keys
  • Braille spinner animation — displayed during streaming responses and tool calls for clear visual feedback
  • Theme system — four built-in themes (dark, nord, monokai, light) switchable at any time with /theme
  • Template system — save and reuse prompt templates with /template add, /template use, /template list, /template delete; stored in ~/.localcode/templates.json
  • Alias system — define custom command shortcuts with /alias <name> <command>; stored in ~/.localcode/aliases.json
  • /explain — stream an AI explanation of any file or the last code snippet in the conversation
  • /test — auto-detects and runs jest, vitest, pytest, cargo test, or go test; on failure, offers an AI-generated fix
  • /share — exports the full conversation as a self-contained HTML file
  • Session history browser — /history [n] lists and restores past sessions archived in ~/.localcode/sessions/
  • /git panel — interactive git panel with status, log, stash, and branch views; raw git commands also pass through
  • /watch — watches a file with fs.watch and re-runs the last message automatically on every change
  • Auto-context injection — on startup, automatically injects git log and git status into context when no .nyx.md project file is found
  • Multi-file diff summary — after the agent edits multiple files, a grouped diff summary is shown
  • Collapsible tool output — long tool outputs are truncated and expandable to keep the UI clean
  • Syntax highlighting — code blocks receive keyword, string, number, and comment highlighting
  • Plugin system — drop any .js file into ~/.localcode/plugins/ to register custom slash commands; manage with /plugins
  • /image — vision input via base64 encoding, compatible with Claude, GPT-4o, and Ollama llava
  • Streaming token counter — live +N▌ token display in the header updates during streaming
  • TF-IDF semantic search — /index builds a local search index of project files; /search <query> queries it
  • New QoL commands — /cd, /ls, /find, /ping added for quick filesystem and network tasks
  • Dynamic version in header — version number is read directly from package.json at runtime
  • Token progress bar — visual progress bar in the header shows context window utilization
  • Message timestamps — system messages and tool call messages now display a timestamp
  • Auto-save — session is automatically saved to disk after every AI response
  • Input character counter — footer displays a live character count while typing
  • Windows + Wayland clipboard support — /copy now works on Windows (clip.exe) and Wayland (wl-copy)
  • Revamped website — tabbed command browser, feature comparison table, plugin showcase, and terminal demo

Changed

  • Word wrap applied to all message text for improved readability on narrow terminals

3.0.0 - 2026-03-16

Added

  • Markdown renderer (MarkdownText component) — renders fenced code blocks, headers (#–###), ordered and unordered lists, bold text, and inline code in the terminal
  • Hooks system — run shell scripts automatically on PreToolUse, PostToolUse, and Notification events; configured via ~/.localcode/hooks.json
  • Three-tier approval mode — suggest (default), auto-edit, and full-auto; switch at runtime with /mode or grant blanket approval with /allowall
  • AbortController integration — pressing Escape cancels the current in-flight streaming request immediately
  • Memory hierarchy — global memory in ~/.nyx.md plus per-project memory in <project>/.nyx.md; manage with /memory
  • MCP (Model Context Protocol) — connect external tool servers over stdio or HTTP transport; manage with /mcp
  • Multiline input — toggle multiline editing mode with Ctrl+E; lines are numbered, submit with Ctrl+D
  • Unified diff — /diff now shows a proper unified diff computed with a pure-JS LCS algorithm
  • New file tools — delete_file, move_file, search_files, find_files added to the agent tool set
  • New slash commands — /review, /init, /doctor, /memory, /hooks, /mode, /steps, /sys, /persona, /pin, /unpin, /web, /export, /undo, /todo, /cost, /mcp
  • Per-model cost table — token cost estimates for Claude 4.6, GPT-4.1, and o3 shown via /cost
  • Configurable max steps — /steps <n> sets the agent loop step limit; default is 20
  • Auto-checkpoint — session checkpointed automatically every 20 messages
  • Polished NyxHeader — dynamic mood-based colors and a v3.0 version badge

Security

  • Shell injection prevention — all exec() calls replaced with execFile() to eliminate shell injection vectors
  • Path traversal protection — tool executor now validates and rejects paths that escape the working directory

2.3.0 - 2025-01-01

Added

  • Real multi-step agent loop — the agent now executes tools across multiple reasoning steps rather than a single-shot response
  • MCP server support — connect to MCP servers over stdio transport
  • Ollama provider — local model support via Ollama
  • Claude SSE provider — streaming support for Anthropic Claude models
  • OpenAI-compatible provider — works with any OpenAI-compatible API endpoint
  • Tool set — read_file, write_file, patch_file, list_dir, run_shell, git_operation
  • Session persistence — sessions are saved to disk with checkpoint and restore support
  • /commit — generates a conventional commit message using AI and commits staged changes
  • /diff — shows a diff of all files modified during the current session
  • /context — adds a file or folder to the active context window
  • Inline context injection — @file and @dir syntax in any message injects file or directory contents inline

2.2.0 - 2024-12-01

Added

  • Custom system prompt — set a persistent system-level instruction with /sys
  • Personas — five built-in personas: pair-programmer, senior-engineer, rubber-duck, code-reviewer, minimal; switch with /persona
