Linux File Search Query Formatter Model

Model Overview

• Converts NL queries → structured tag–value pairs
• Supports all schema attributes from the Linux File Search NLI dataset:
  • File attributes (file_type, extension, size_kb, owner, group, permissions)
  • Temporal attributes (created_year, modified_year)
  • Semantic attributes (language, purpose, contains_text, is_executable, hidden)
  • Path scope and generic tags (path_scope, important, autogenerated, obsolete, archived)
• Outputs deterministic JSON suitable for safe post-processing into find commands or other Linux search engines

Intended Use

• Formatting natural language queries into structured representations
• Query-to-Structure pipelines for semantic file search
• Integration with safe Linux CLI search tools (find, grep, fd)
• Training downstream Q2I or NLI models

• Direct command execution without validation
• General-purpose conversation
• Use outside Linux file systems without adaptation

Model Architecture

• Type: Decoder-only (seq2seq transformer)
• Input: Natural language query
• Output: JSON-like structured representation (tag:value pairs)
• Precision: bf16
• Training Dataset: Linux File Search NLI (~3500 synthetic examples)
• Training Objective: Map NL queries → structured schema attributes

Limitations

• English-only queries
• Linux-centric file system abstraction
• Temporal reasoning limited to years
• Logical operators may require post-processing
• Does not execute commands

Safety Considerations

• Outputs are structured representations, not shell commands
• Any conversion to executable commands should be validated and sandboxed
• Prevent execution of arbitrary system commands from model output
