When Projects Grow, Context Breaks

Have you ever worked tirelessly on a detailed software project, only to find yourself lost as it grows more complex? It's like trying to follow a story with missing pages, the more you progress, the more context you lose.

LLMs face the same struggle. They have a memory cap, the context window. Every extra token costs money and risks drift or hallucination. As projects expand, essential context becomes fragmented or compressed multiple times, causing inaccuracies and frustrating misinterpretations.

Think of it like this:

Imagine copying a long recipe onto sticky notes. One note says "fold in the egg whites," but the note that told you to separate the eggs sits in another stack. Another says "bake for 12 minutes," but as the stack grows, the note that says "preheat oven" goes missing.

When the model can only see a handful of notes at a time, it loses the thread that ties steps together. Small gaps become misunderstandings, and sometimes turn into confident hallucinations.

# contextus-example.py
from contextus import compile_context
# Simple guardrails
policy = {drop_if_matches: [
r"rm\s+-rf\s+/(?!tmp)", # destructive shell
r"DROP\s+TABLE\s+\w+", # DB wipe
]}
result = compile_context(
messages=[ ... ], # your chat/code/doc blocks
policy=policy,
strategy="structure-aware",
scoring="query-aware"
