hash

BLAKE3 checksum computation for files. Standalone BLAKE3 checksum computation for one or more files. Workload: CPU-bound (BLAKE3 hashing).

list

Directory listing with metadata. Directory listing with metadata, gitignore support, and depth control. Workload: I/O-bound (directory walk + stat per entry).

move

Atomic file move and rename. Atomic file move with cross-device fallback to copy-then-delete. Workload: I/O-bound (rename syscall + fsync).

outline

v14 Tier 3 (v0.1.12): tree-sitter S-expression query against a file. v14 Tier 3 subcommand (v0.1.12): outline — extract the high-level structure of a source file (functions, classes, structs, enums, traits, modules, top-level consts) as NDJSON. Uses tree-sitter-language-pack.

query

v14 Tier 3 (v0.1.12): tree-sitter S-expression query against a file. v14 Tier 3 subcommand (v0.1.12): query — walk a source file’s tree-sitter parse tree and emit AST nodes as NDJSON. Uses tree-sitter-language-pack for parser provisioning (305 languages; downloads on first use; cache local).

read
