The Forge file walker selects files by applying hierarchical filters—depth limits, breadth caps, size constraints, and binary detection—starting from a configured directory, where max_walker_depth corresponds to the max_depth field that defaults to 5 levels.

The Forge file walker is a Rust-based filesystem traversal engine found in the antinomyhq/forgecode repository. When the LLM needs context from a codebase, the walker returns a filtered Vec<File> containing only the entries that satisfy multiple safety and performance constraints. Understanding these filters and
