Extract path traversal and symlink validation from kajet-writer into reusable module in kajet-core. Security features: - Blocks .. components (path traversal) - Blocks absolute paths - Verifies canonical paths after symlink resolution - Handles non-existent paths (for creation workflows) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Remove duplicate validation functions and use the shared utilities from kajet-core::path_validation module. All writer tests pass without regression. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Move path validation utilities to kajet-parser to avoid cyclic dependencies. Add security tests and make vault_tree async to enable validation. Security fixes: - Block .. components (path traversal) - Block absolute paths - Verify canonical paths after symlink resolution Breaking change: vault_tree() is now async and requires .await Also update kajet-mcp to call async vault_tree correctly. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add explicit validation for tree tool parameters: - Reject depth=0 with clear error message - Reject size=0 with clear error message - Reject invalid show values (only 'folders' or 'files' allowed) - None/missing show defaults to 'folders' Previously invalid parameters would silently fallback or produce confusing behavior. Now they return explicit errors. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add internationalized error messages for tree tool parameter validation: - tree_invalid_show: Invalid show mode error - tree_depth_zero: Depth must be at least 1 - tree_size_zero: Size must be at least 1 Available in English and Polish. MCP handler now uses t!() macro for all validation errors. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
