All notable changes to CodeAgent are documented in this file.

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

Unreleased

Added

  • design/ directory with comprehensive architectural documentation
    • C4 model diagrams (Context, Container, Component, Code) using Mermaid.js
    • 8 Architecture Decision Records covering Ollama backend, zero dependencies, dual tool-call parsing, safety model, context windowing, DuckDuckGo search, tool registry, and cross-platform shell execution

1.0.0 - 2026-02-11

Added

  • Core agent engine with multi-turn LLM-tool loop (max 50 turns, configurable)
  • Ollama integration via REST API — zero API keys, fully local inference
  • 11 built-in tools:
    • File operations: read_file, write_file, edit_file, list_directory
    • Code search: grep (regex), glob (pattern matching)
    • Shell execution: bash (cross-platform with safety checks)
    • Git operations: git (with safety rails for destructive commands)
    • Web: web_search (DuckDuckGo), web_fetch (URL content extraction)
    • Discovery: scan_agents (GitHub-based coding agent scanner)
  • Safety system with three tiers: blocked commands, warned commands, and auto-approved read-only operations
  • Secret detection for API keys, passwords, private keys, and sensitive files
  • Conversation management with context windowing (200 messages / 100K chars) and JSON persistence (/save, /load)
  • Configuration system with layered defaults: dataclass defaults → config file (~/.codeagent/config.json) → CLI overrides
  • Interactive REPL with slash commands: /help, /status, /model, /models, /scan, /config, /cd, /verbose, /save, /load, /version
  • Single-prompt mode for one-shot execution (codeagent "prompt")
  • Cross-platform support for Windows, Linux, and macOS
  • Zero external dependencies — built entirely on Python 3.10+ standard library
  • Windows launchers:
    • CodeAgent.bat — double-click launcher with auto Ollama startup
    • CreateDesktopShortcut.bat / make_shortcut.ps1 — desktop shortcut creators
  • Installers: install.bat (Windows), install.sh (Linux/macOS)
  • Documentation: README.md, docs/ARCHITECTURE.md, docs/CONFIGURATION.md, docs/QUICKSTART.md, docs/TOOLS.md, docs/AGENT_SCANNER.md
  • Test suite: 50 tests (17 integration, 33 unit) covering engine and all tools
