v1.13.0 — LSP Multi-Language + Tests + Clean Config

Highlights

• LSP multi-language — Default support for Python (pyright), Rust (rust-analyzer), Go (gopls) + TypeScript/JavaScript
• Configurable LSP servers — Add custom LSP servers via lspServers in .coding-agent.json
• Full test coverage — 181 unit tests for MCP, LSP, persistence, toolRegistry, models
• Better MCP error messages — stderr captured in close errors
• Clean defaults — Empty mcpServers/lspServers in .coding-agent.json to avoid startup failures

Changes

• src/lsp/config.ts: LSP server config loader
• DEFAULT_LSP_SERVERS extended with pyright, rust-analyzer, gopls
• loadLSPConfig wired into agent.ts and server.ts startup
• StdioTransport: stderr captured and included in close errors
• 5 new test files (mcp, lsp, persistence, toolRegistry, models)
• transport.ts: fixed pending response resolution in readline handler
• Fixed config loaders: findProjectRoot returns dir path, not file path

Test suite

• 181 unit tests (previously 138)
• 12 test files covering all modules

v1.12.0 — Standalone Binary + MCP HTTP Transport

Highlights

• Standalone binary — compile with pkg (no Node.js required)
• MCP HTTP/SSE transport — connect to remote MCP servers via HTTP+SSE
• Build scripts — npm run build:binary, build:binary:win, build:binary:web

Changes

• pkg configuration with Windows/Linux/macOS targets
• scripts/build-binary.js helper
• HTTPTransport for SSE-based MCP connections

• Persistence: sessions/ directory with auto-title & modelPreset metadata
• Models: anthropic, together, perplexity, xai, cohere providers added
• Tool registry: central registry combining built-in + MCP + LSP tools

v1.10.0 — Web UI: Diff Viewer, Session Manager, Slash Commands

Web UI Enhancements

• Diff Viewer — when files are written, replaced, or appended, the UI shows a line-level LCS diff (green + / red -) so you can see exactly what changed.
• Session Manager — create multiple sessions, switch between them, see auto-generated titles from the first message, model used, and message count.
• Slash Commands — type /active, /model 2, /safe, /allow, /reset, /models, /exit\ directly in the web input.
• Help Modal — click the ?\ button for a complete usage guide including model switching, commands reference, and diff viewer explanation.
• SSE streaming — uses \etch\ + \ReadableStream\ (no \EventSource\ dependency) for reliable streaming.

Server

• Diff events sent as SSE between \ ool_call\ and \ ool_result\ for \write_file,
  eplace_in_file, \�ppend_file\
• Session endpoints: \GET /api/sessions, \GET /api/sessions/:id\
• Session metadata tracking (auto-title, model label, message count, creation time)
• \sessions\ map exported for test access

Tests

• 137 unit tests passing (+8 new: session endpoints + diff event integration)

v1.9.0 — AGENTS.md + Comprehensive Test Suite

v1.9.0 — AGENTS.md + Comprehensive Tests

New

• AGENTS.md support: Drop \AGENTS.md\ or .coding-agent.md\ in your project root. Auto-loaded and injected into system prompt for both CLI and Web.

• Sample \AGENTS.md\ included for the project itself

Tests: 41 → 84 unit tests (+ 35 integration = 119 total)

• \CodingAgent.test.ts\ (11 tests): execute loop, stream parsing, stuck detection, retry/timeout, HTTP 429/500 error handling
• \loadProjectContext.test.ts\ (7 tests): file lookup, directory walk, empty file, both naming conventions
• \ileManager.test.ts\ (26 tests): all 13 tools (write, read, list, copy, move, delete, search, replace, run, append, folder ops, file_info) + safe mode + unknown tool

Fixes

• \withRetryAndTimeout\ preserves original error properties (fixes 429 status detection during auto-fallback)
• \deleteFolder\ handles Windows \ERR_FS_EISDIR\ (was only checking \ENOTEMPTY)

Changed

• v1.8.0 → v1.9.0
