-
Explanation
The prior content-exposure path is addressed.
MultiSearchReplaceDiffStrategyno longer places search text, best-match text, or original-file excerpts in failure errors; it reports only lengths, scores, locations, and fixed guidance.ApplyDiffToolnever rendersDiffResult.details, and both failure and partial-apply paths format only failed error strings. The new regression tests inject file, search, and detail secrets and assert that model, UI, recorded-error, and partial-apply outputs exclude them. No changed path bypasses access validation, approval, or executes unvalidated input. Prior failure addressed: The current strategy removes Search Content, Best Match Found, and Original Content from failPart.error. ApplyDiffTool omits details on fallback, failure, and partial-apply paths. Added tests verify secret-like values are absent from all relevant outputs.
Full details: Persistence Integrity
-
Explanation
No changed persistence path meets the failure condition. In
ApplyDiffTool, the PR does not alter the awaited persistence calls:saveDirectlyandsaveChangesremain awaited at lines 180 and 225. The new partial-apply logic runs after those calls and reportsApplied X of Y diff blocks, with retry guidance.MultiSearchReplaceDiffStrategyonly returns in-memory content andblockCount; it does not write state. ExistingDiffViewProvider.saveDirectlyfile writing is outside the PR diff.
Full details: Lifecycle Resource Cleanup
-
Explanation
No changed lifecycle path can leak a resource or duplicate work. The PR changes diagnostic formatting, marker hints, failure counting, and the
DiffResult.blockCounttype. The changedApplyDiffTool.executepath adds string formatting only; itsreset()andprocessQueuedMessages()calls remain on the existing success, error, and catch paths. No added listener, watcher, timer, task, provider subscription, cancellation, disposal, or restart operation appears in the changed files.

Full details: Regression Evidence
-
Explanation
The PR changes durable chat content shown to users, but it adds no Playwright component snapshot.
ApplyDiffToolnow sends new multi-failure and truncated diagnostics throughtask.say("diff_error", formattedError)(src/core/tools/ApplyDiffTool.ts:95-117).Task.saypersists that message (src/core/task/Task.ts:2843-2858), andChatRowrenders it throughErrorRow(webview-ui/src/components/chat/ChatRow.tsx:1037-1047). The new tests assert mocked tool results andtask.saycalls (src/core/tools/__tests__/applyDiffTool.failureReporting.spec.ts:166-176,357-375), but no Playwright visual test or snapshot covers the changeddiff_errorrendering.Resolution
Add a Playwright component visual test for the
diff_errorchat state with representative multi-block, abbreviated, and truncated diagnostics. Commit the generated snapshots and verify the persisted message renders without clipping or layout regressions.

Addressed the outside-diff finding in 5884f8c: the strategy now returns the parsed block count, and ApplyDiffTool uses it, falling back to raw marker lines only when the count is absent. Added a parser regression test for an inline marker that repair splits into a second block, plus a tool test. 135 focused tests, eslint, and tsc pass; CI is green. @coderabbitai review |

- Around line 122-123: Update the test around the multi-search-replace
marker-hint result to assert that `result.content` is `ALPHA x\nbeta`,
confirming the first repaired block changed `alpha` to `ALPHA x`; keep the
existing block-count and failure-count assertions.
After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Re the Security Boundaries pre-merge error: this PR does not create that exposure. On origin/main, ApplyDiffTool.ts:90-107 already forwards failPart.error plus JSON details inside error_details, and multi-search-replace.ts:544-580 already builds Search Content, Best Match Found and Original Content. This PR changes how many failures are reported and how they are formatted, not what diagnostics exist. The content is the user's workspace file that the model can already read with read_file; it is the tool's core retry diagnostic. Redacting it would be a separate behavior change outside this PR's scope. Per .coderabbit.yaml, a defect this PR does not create belongs in follow-up candidates, not changes requested. A maintainer needs to decide whether to use the reviewers-only override or open a follow-up issue. The Description check is only a warning. |
…ly reports Only the first failed block keeps Search/Best Match/Original Content sections (main parity); later blocks and the partial-apply result keep diagnostics only.

Stop echoing search, best-match and original file content from failed SEARCH blocks and never forward DiffResult details. Failures now carry numeric scores, line locations and constant hints for single, multi-block, partial-success and fallback paths.

Addressed in 02db12b. Security Boundaries: `MultiSearchReplaceDiffStrategy` no longer emits Search Content / Best Match Found / Original Content; failures carry only numeric scores, lengths, best-match line location and constant hints. `ApplyDiffTool` never renders `DiffResult.details` on single, multi, partial-success or fallback paths. Regression tests in applyDiffTool.failureReporting.spec.ts use the real strategy with synthetic markers in file/search/details fields and assert absence in the tool result, diff_error UI message and recorded error. Description: no approved, assigned issue exists for this change; the PR body now states this instead of claiming a link, pending maintainer assignment. @coderabbitai review |
