From a28a565ead655180dc5af229e31fb7a5d3c779b4 Mon Sep 17 00:00:00 2001 From: can1357 Date: Wed, 11 Feb 2026 09:03:48 +0100 Subject: [PATCH] feat(coding-agent/patch): enhanced hashline edit validation and error recovery with deduplication and format checking - Added noopEdits array to applyHashlineEdits return type to track edits that produce no changes. - Added validation to reject edits with wrong-format fields (old_text/new_text from replace mode, diff from patch mode) that indicate model confusion. - Added additionalProperties tolerance to hashline edit schemas to allow flexible field handling. - Added deduplication logic to remove duplicate edits targeting the same line(s) with identical destination content. - Improved error handling for missing end fields in edit ranges by returning single-line specs instead of requiring both start and end. - Enhanced no-op error recovery guidance in prompts with detailed instructions to re-read file and function context after consecutive no-op errors. --- packages/coding-agent/CHANGELOG.md | 19 ++- packages/coding-agent/src/patch/hashline.ts | 88 +++++++++- packages/coding-agent/src/patch/index.ts | 150 ++++++++++-------- .../src/prompts/tools/hashline.md | 6 +- .../coding-agent/test/core/hashline.test.ts | 1 -

### Added +- Added `noopEdits` array to `applyHashlineEdits` return value to report edits that produced no changes, including edit index, location, and current content for diagnostics +- Added validation to detect and reject hashline edits using wrong-format fields (`old_text`/`new_text` from replace mode, `diff` from patch mode) with helpful error messages +- Added `additionalProperties: true` to all hashline edit schemas (`single`, `range`, `insertAfter`, and root) to tolerate extra fields from models - Added whitespace normalization in line reference parsing to tolerate spaces around colons (e.g., `5 : ab` now parses as `5:ab`) - Added `remaps` property to `HashlineMismatchError` providing quick-fix mapping of stale line references to corrected hashes - Added warnings detection in `applyHashlineEdits` to alert users when edits affect significantly more lines than expected, indicating possible unintended reformatting - Added diagnostic output showing target line content when an edit produces no changes, helping users identify hash mismatches or incorrect replacement content - Added `{{hashline}}` Handlebars helper to compute accurate `LINE:HASH` references for prompt examples and documentation +- Added deduplication of identical hashline edits targeting the same line(s) in a single call +- Added `replacement` as accepted alias for `content` in `insertAfter` operations +- Added graceful degradation of `range` edits with missing `end` field to single-line edits +- Added `additionalProperties: true` to hashline edit schemas to tolerate extra fields from models ### Changed +- Improved no-op edit diagnostics to use `noopEdits` array from `applyHashlineEdits`, providing precise line-by-line comparison when replacements match current content +- Enhanced error messages for wrong-format hashline edits to guide users toward correct operation syntax +- Strengthened hashline prompt guidance to emphasize that `replacement` must differ from current line content and clarify no-op error recovery procedures +- Improved hashline prompt to clarify atomicity: all edits in one call are validated against the original file state, with line numbers and hashes referring to the pre-edit state +- Added explicit instruction in hashline prompt to preserve exact whitespace and formatting when replacing lines, changing only the targeted token/expression +- Added guidance in hashline prompt for swap operations: use two `single` operations in one call rather than attempting to account for line number shifts +- Strengthened anti-reformatting instructions in hashline prompt to reduce formatting-only failures +- Improved no-op error recovery guidance in hashline prompt to prevent infinite retry loops - Renamed hashline edit operation keys from `replaceLine`/`replaceLines` to `single`/`range` for clearer semantics - Renamed hashline edit field `content` to `replacement` in `single` and `range` operations to distinguish from `insertAfter.content` - Improved no-op edit diagnostics to show specific line-by-line comparisons when replacements match current content, helping users identify hash mismatches or formatting issues @@ -39,6 +53,9 @@ ### Fixed +- Fixed `range` edits with missing `end` field to gracefully degrade to single-line edits instead of crashing +- Fixed `insertAfter` operations to accept both `content` and `replacement` field names for consistency with other edit types +- Fixed deduplication logic to correctly identify and remove identical hashline edits targeting the same line(s) in a single call - Fixed range-based edits to prevent invalid mutations when hash relocation changes the number of lines in the target range - Fixed multi-edit application to use original file state for all anchor references, preventing incorrect line numbers when earlier edits change file length diff --git a/packages/coding-agent/src/patch/hashline.ts b/packages/coding-agent/src/patch/hashline.ts index b9c29e131..3aa819a70 100644 --- a/packages/coding-agent/src/patch/hashline.ts +++ b/packages/coding-agent/src/patch/hashline.ts @@ -28,16 +28,23 @@ function parseHashlineEdit(edit: HashlineEdit): { spec: ParsedRefs; dst: string }; } if ("range" in edit) { -
