0.1.0 - 2026-02-28

Initial release.

Added

Core infrastructure

  • Daemon architecture: one long-lived process per project root over a Unix domain socket
  • Auto-start: daemon spawned on first use, shuts down after inactivity
  • Auto-install language servers to ~/.krait/servers/ (vtsls, gopls, rust-analyzer)
  • SQLite symbol index with BLAKE3 file hashing and file-watcher-based cache invalidation
  • Dynamic multi-root LSP: one language server process per language, workspace folders attached dynamically via workspace/didChangeWorkspaceFolders
  • Monorepo support: auto-detect all workspace roots recursively (tested up to 76 workspaces)
  • Output formats: compact (LLM-optimized), json, human

Navigation commands

  • krait find symbol <name> — locate symbol definition via LSP workspace/symbol
  • krait find refs <name> — find all references via textDocument/references
  • krait list symbols <path> — semantic file outline via textDocument/documentSymbol
  • krait read file <path> — file contents with line numbers, binary detection
  • krait read symbol <name> — extract symbol body, --signature-only flag

Editing commands

  • krait edit replace <symbol> — replace symbol body from stdin
  • krait edit insert-after <symbol> — insert code after a symbol from stdin
  • krait edit insert-before <symbol> — insert code before a symbol from stdin
  • Atomic file writes via temp-file-then-rename (no partial file corruption)

Agent commands

  • krait hover <symbol> — type info and documentation via textDocument/hover
  • krait format <path> — LSP formatter via textDocument/formatting
  • krait rename <symbol> <new-name> — cross-file rename via textDocument/rename
  • krait fix [path] — apply LSP quick fixes via textDocument/codeAction

Diagnostics

  • krait check [path] — LSP diagnostics, --errors-only flag, exit code 1 on errors (CI-friendly)
  • krait status — daemon health, LSP state, cache stats, index dirty file count

Configuration

  • krait init — auto-detect workspaces and generate .krait/krait.toml
  • krait init --dry-run — preview config without writing
  • krait daemon start|stop|status — daemon lifecycle management

Language support (v0.1)

  • TypeScript / JavaScript via vtsls
  • Go via gopls
  • Rust via rust-analyzer
  • C/C++ via clangd

Performance (benchmarked on open-source projects, warm daemon)

  • Warm find symbol: 32–59ms across TypeScript and Go projects
  • Warm hover: 40–70ms (excluding one-time LSP type-load on first call)
  • Warm check: 37–50ms
  • Cold start (daemon off, index cached): 146–586ms depending on workspace size
