Context Mode Review 2026 - The Missing Half of the AI Agent Context Problem

The Problem

Every AI agent developer knows this: your agent runs a browser tool, dumps a 300KB DOM snapshot into context, and suddenly your $200/month token budget evaporates. Compression tools like Headroom help after the fact. Context Mode stops it at the source.

Four Pillars

• Sandboxed tool execution - intercepts output, strips structural noise
• Session continuity - SQLite FTS5, context survives restarts
• Code-thinking paradigm - one batch query instead of 47 individual Read() calls
• Non-intervention routing - controls input without modifying model tone

Real Results

Headroom vs tokdiet vs Context Mode

They don't overlap. They layer:

• Headroom → passive compression proxy
• tokdiet → CLI transport savings
• Context Mode → behavioral orchestration + session persistence

Stack all three for maximum savings.
