From 2f81da0becf920d3ee344ef62721c3f1709cdca4 Mon Sep 17 00:00:00 2001 From: can1357 Date: Tue, 10 Feb 2026 17:03:46 +0100 Subject: [PATCH] feat(coding-agent/patch): enhanced hashline edits to strip prefixes and preserve whitespace-only changes - Added automatic stripping of `LINE:HASH|` display prefixes and unified-diff `+` markers from replacement content in hashline edits. - Enhanced replace edits to preserve original whitespace on lines where only whitespace differs, preventing spurious formatting diffs when models reformat code. - Added helper functions `stripNewLinePrefixes()`, `preserveWhitespaceOnlyLines()`, and `equalsIgnoringWhitespace()` to improve edit robustness. --- packages/coding-agent/CHANGELOG.md | 3 +- packages/coding-agent/src/patch/hashline.ts | 90 +- .../src/prompts/tools/hashline.md | 4 +- .../coding-agent/src/prompts/tools/patch.md | 2 +- .../coding-agent/src/prompts/tools/replace.md | 2 +- ...-haiku-4-5_hashline_2026-02-10T15-12-24.md | 2283 +++ ...ude-haiku-4-5_patch_2026-02-10T15-13-20.md | 2682 ++++ ...sonnet-4-5_hashline_2026-02-10T15-06-31.md | 942 ++ ...sonnet-4-5_hashline_2026-02-10T16-10-42.md | 691 + ...de-sonnet-4-5_patch_2026-02-10T15-03-14.md | 749 + ...flash-lite_hashline_2026-02-10T15-39-27.md | 5853 ++++++++ ...flash-lite_hashline_2026-02-10T15-58-18.md | 4223 ++++++ ..._5-flash-lite_patch_2026-02-10T15-39-13.md | 5440 +++++++ ..._1-codex-mini_patch_2026-02-10T16-05-12.md | 1234 ++ ...-reasoning_hashline_2026-02-10T15-20-00.md | 2262 +++ ...non-reasoning_patch_2026-02-10T15-29-33.md | 12248 ++++++++++++++++ 16 files changed, 38697 insertions(+), 11 deletions(-) create mode 100644 packages/react-edit-benchmark/runs/claude-haiku-4-5_hashline_2026-02-10T15-12-24.md create mode 100644 packages/react-edit-benchmark/runs/claude-haiku-4-5_patch_2026-02-10T15-13-20.md create mode 100644 packages/react-edit-benchmark/runs/claude-sonnet-4-5_hashline_2026-02-10T15-06-31.md create mode 100644 packages/react-edit-benchmark/runs/claude-sonnet-4-5_hashline_2026-02-10T16-10-42.md create mode 100644 packages/react-edit-benchmark/runs/claude-sonnet-4-5_patch_2026-02-10T15-03-14.md create mode 100644 packages/react-edit-benchmark/runs/gemini-2_5-flash-lite_hashline_2026-02-10T15-39-27.md create mode 100644 packages/react-edit-benchmark/runs/gemini-2_5-flash-lite_hashline_2026-02-10T15-58-18.md create mode 100644 packages/react-edit-benchmark/runs/gemini-2_5-flash-lite_patch_2026-02-10T15-39-13.md create mode 100644 packages/react-edit-benchmark/runs/gpt-5_1-codex-mini_patch_2026-02-10T16-05-12.md create mode 100644 packages/react-edit-benchmark/runs/grok-4-fast-non-reasoning_hashline_2026-02-10T15-20-00.md create mode 100644 packages/react-edit-benchmark/runs/grok-4-fast-non-reasoning_patch_2026-02-10T15-29-33.md diff --git a/packages/coding-agent/CHANGELOG.md b/packages/coding-agent/CHANGELOG.md index dc82b7527..7f07e9fb6 100644 --- a/packages/coding-agent/CHANGELOG.md +++ b/packages/coding-agent/CHANGELOG.md @@ -1,7 +1,6 @@ # Changelog ## [Unreleased] - ### Breaking Changes - Replaced `edit.patchMode` boolean setting with `edit.mode` enum;

I've restored the missing guard clause after line 38. The 3-line pattern checks if `state` is falsy and returns `null` early if it is, which prevents accessing properties on an undefined or null `state` object.
