Synaptic 1.0 Introduces Change Contracts to Recover Implicit Requirements

Texbobcat · reddit · 2026-08-28

Synaptic 1.0 introduces "Change Contracts" to address the bottleneck where coding agents fail because they miss implicit requirements scattered across codebases. Citing SWE-RPG and RACE-Bench research showing 31.5% resolution rates and frequent requirement gaps, Synaptic analyzes code graphs, dependencies, and tests to generate a contract defining scope, evidence, and unknowns. The contract is cryptographically sealed and verified post-implementation to ensure public symbols remain intact and tests pass, preventing unrecorded assumptions. This workflow stabilizes the definition of success for both developers and tools, particularly useful for legacy or interconnected repositories.
