A three-pass 'Context Compiler' built with Python's standard library addresses this by tracing only what a target file actually imports and calls (Pass 1: symbol resolution), stripping dependency files down to function signatures and docstrings (Pass 2: interface extraction), and assembling a tiered context with exact token costs (Pass 3). Benchmarked on two real Python repos, it reduced prompt sizes by 69–74% with compile times under 75 ms. The tool explicitly flags dynamic dispatch, event-driven decorators, and name collisions rather than guessing, and is tunable via a max_hops parameter. Source code and runnable demos are available on GitHub. ## Full article daily.dev links to this article rather than hosting it.
