Two Papers Argue the Constraint on Coding Agents Is Now Specification and Memory, Not Model Capability
One proposes a spec-driven development lifecycle for million-token coding agents, the other spawns Claude Code instances pre-loaded with prior work instead of starting each session from an empty context.
Coding agents backed by context windows running from hundreds of thousands to millions of tokens are restructuring the software development lifecycle, argue the authors of SDAD, posted to arXiv on 24 August. Their proposal, spec-driven agen…

Part of a tracked trend
Context and Memory Become the Agent Bottleneck
As agent context windows grow past the size of the codebases they work on, the limiting factor keeps shifting from model capability toward specification quality and persistent memory, moving competitive advantage and margin toward the harness layer rather than the model.
