Detect when write_file / patch calls fail during a turn and are never superseded by a successful write to the same path. When the final text response is delivered, append an advisory footer listing the files that did NOT change — so models that over-claim 'patched 5 files' after 4 silent failures can't hide the lie. Catches the failure mode reported in Ben Eng's llm-wiki session: grok-4.1-fast issued batches of parallel patches, half failed with 'Could not find old_string', and the agent summarised the turn claiming every file was edited. The user had to manually run 'git status' each turn to catch it. The verifier is a pure post-hoc check on tool results — no new LLM calls, no synthetic messages injected into history (prompt cache preserved), no changes to tool argument dispatch. Per-turn state is keyed by path; a later successful write to the same path clears the failure entry so single-file retry recovery is not flagged. Wired into both _execute_tool_calls_concurrent and _execute_tool_calls_sequential, so batched parallel patches and one-at- a-time edits are both covered. Footer emission happens after the agent loop exits, before transform_llm_output / post_llm_call plugin hooks run, so plugins still see (and can modify) the augmented text. Config: display.file_mutation_verifier (bool, default true) + HERMES_FILE_MUTATION_VERIFIER env override. 31 unit tests in tests/run_agent/test_file_mutation_verifier.py cover target extraction (write_file, patch-replace, patch-v4a single and multi-file), error-preview extraction (JSON .error field and plain string), per-turn state transitions (first-error-wins on repeated failure, success supersedes failure), footer rendering (truncation at 10 entries, user-actionable hint), and env/config precedence. Companion docs updated: user-guide/configuration.md + reference/environment-variables.md. |
