From 699ae9a6cca3736ffe0b0c7cb6ee8dac12e0279b Mon Sep 17 00:00:00 2001 From: CTO Hermes Date: Wed, 3 Jun 2026 00:56:38 +0700 Subject: [PATCH 1/4] feat: inject static analysis context into review prompt (#140) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add optional clippy output injection to reduce false positives: - New config: review.static_analysis.auto_clippy (run cargo clippy) - New config: review.static_analysis.clippy_output_file (read pre-computed) - New module: engine/static_analysis.rs with clippy runner + 5 tests - Prompt injects context between file paths and diff Zero-config — no behavior change when not configured. 229 tests pass, clippy clean, fmt clean.
