 - **Environment-aware**: system prompt includes OS, shell, working directory, and git branch for context
 - **Semantic code tools** (tree-sitter): list_symbols, get_symbol_body, find_definition, find_callers, find_callees — supports TypeScript/TSX and Python

 ### Tool result caching
 
-Read-only tool calls (`read`, `grep`, `find_files`, `list_dir`) are cached per agent turn. Repeated calls with identical arguments within the same turn return cached results, avoiding redundant filesystem I/O. The cache clears automatically before each new prompt, and after `write`/`edit`/`bash` so a re-read sees fresh content.
