# [Agent Readability Spec \(ARS 0.2\)](https://rebilder.com/spec/ars)

> The published, versioned standard behind every Rebilder score: 100 points across seven dimensions, with measured checks separated from heuristic ones and every check carrying its evidence. The full specification text renders at /spec/ars.

## Principles

The scoring function is pure over a content-addressed evidence bundle: no LLM, no randomness, and no clock in the scoring path. A heuristic value never renders without its label. Ruleset ars-0.2 ships with a public conformance corpus.
