Preview — sketch editorial system (hand-drawn annotations + notebook diagrams)
Context engineering for agency delivery
Most agency listicles stop at logos and case studies. The operators hiring AI-native shops in 2026 need proof of delivery stack — how context, skills, and workflows survive the handoff from strategist to executor.
How we picked these agencies
We shortlist agencies on publicly verifiable signals: case studies, service positioning, pricing transparency, and documented workflows. A shop with strong creative but no agent inheritance caps out on margin — every engagement restarts from zero.
Why this matters for listicles
Sketch annotations mark framework terms readers should remember. Notebook diagrams explain flows without sacrificing crawlable body text. Stats, citations, and Sources stay in real prose — the pen marks are emphasis, not the evidence.
