Full File Reads

GitAuto forces the model to read entire files rather than partial snippets. For files under 2,000 lines, any attempt by the model to read only a portion is overridden, ensuring it always sees the complete file content.

Why This Exists

Partial file reads cause a cascade of problems: missing import statements, unknown type definitions, invisible class fields, and incomplete understanding of function signatures that appeared earlier or later in the file. The result is diffs that look reasonable in isolation but break when applied. The model adds an import that already exists, misses a required field in a data structure, or duplicates a function that was defined outside the truncated window. Full file reads eliminate this entire class of errors by forcing complete context regardless of what the model requests.

Why Models Read Partial Files

When given a tool with offset and limit parameters, models default to reading just 20-50 lines around the area they think is relevant, rather than loading the full file. This is a learned behavior from training data where partial file reads are common - and it is reinforced by instruction-following training that teaches models to be "efficient." But for code generation, partial context leads to duplicate imports, missing fields, and broken diffs. The model ends up optimizing for smaller requests instead of maximizing code correctness.

How It Works

When the model requests to read a file, GitAuto intercepts the request. If the file is under 2,000 lines, GitAuto overrides any partial-read request and returns the entire file content. This happens transparently - the model receives the full file as if it had requested it that way.

The 2,000-line threshold exists because extremely large files would consume too much of the context window. For files above this threshold, truncation parameters are respected to avoid token budget exhaustion.
