From fa97abf0c383bd94c85431dce9c4fc658aa3790e Mon Sep 17 00:00:00 2001 From: "K. Hodges" Date: Sun, 17 May 2026 15:24:10 -0700 Subject: [PATCH] Implemented deterministic diff generation via a new file_writer stage. What changed: - Added file_writer stage support in nightshift/config.py:93, nightshift/agents.py:446, and nightshift/pipeline.py:374. - Added file-block parsing and deterministic patch generation in nightshift/patches.py:65. - file_writer agents now return complete file blocks: ```file:relative/path.py ``` NightShift reads current files and generates the unified diff itself. - Existing patch_validator, patch_normalizer, and patch_apply still run after that. - Switched tiny-lisp-nightshift/nightshift.yaml:51 to type: file_writer. - Updated tiny-lisp-nightshift/agents/implementer.md:1 to request file blocks instead of diffs. - Updated README, tutorial, config reference, and design doc. Also added tests for parsing file blocks, generating multi-file diffs, validating those diffs, and running a full file_writer -> normalize -> validate pipeline. Verification: python -m unittest discover -v passes, 101 tests. --- .nightshift/project-context-chart.md | 84 ++ .nightshift/project-context.md | 2 + .../config.snapshot.yaml | 89 ++
