Closes the gap where write_file skipped the post-edit syntax check that patch already ran, so silent file corruption (bad quote escaping, truncated writes, etc.) would persist on disk until a later read. ## Changes tools/file_operations.py: - Add in-process linters for .py, .json, .yaml, .toml (LINTERS_INPROC). Python uses ast.parse, JSON/YAML/TOML use stdlib/PyYAML parsers. Zero subprocess overhead; preferred over shell linters when both apply. - _check_lint() now accepts optional content and routes to in-process linter first. Shell linter (py_compile, node --check, tsc, go vet, rustfmt) remains the fallback for languages without an in-process equivalent. - New _check_lint_delta() implements the post-first/pre-lazy pattern borrowed from Cline and OpenCode: lint post-write state first; only if errors are found AND pre-content was captured does it lint the pre-state and diff. If the pre-existing file had the SAME errors the edit didn't introduce anything new, so the file is reported as 'still broken, pre-existing' with success=False but a message explaining the errors were pre-existing. If the edit introduced genuinely new errors, those are surfaced and pre-existing ones are filtered out. - WriteResult gains a lint field. - write_file() captures pre-content for in-process-lintable extensions and calls _check_lint_delta after a successful write. - patch_replace() switches from _check_lint to _check_lint_delta, reusing the pre-edit content it already has in scope. tools/file_tools.py: - Update write_file schema description to mention the post-write lint. tests/tools/test_file_operations_edge_cases.py: - Update existing brace-path tests to use .js (shell linter) now that .py is in-process. - Add TestCheckLintInproc (9 tests) covering Python/JSON/YAML/TOML in-process linters. - Add TestCheckLintDelta (5 tests) covering the post-first/pre-lazy short-circuit, new-file path, and the single-error-parser caveat. ## Performance In-process linters are microseconds per call (ast.parse, json.loads). The hot path (clean write) runs exactly one lint — matches main's cost for patch. Pre-state capture is skipped when the file has no applicable linter. Measured 4.89ms/write average over 100 .py writes including lint. ## Inspiration - Cline's DiffViewProvider.getNewDiagnosticProblems() — filters pre-write diagnostics from post-write diagnostics (src/integrations/editor/DiffViewProvider.ts). - OpenCode's WriteTool — runs lsp.diagnostics() after write and appends errors to tool output (packages/opencode/src/tool/write.ts). - Claude Code's DiagnosticTrackingService — captures baseline via beforeFileEdited() and returns new-diagnostics-only from getNewDiagnostics() (src/services/diagnosticTracking.ts). ## Validation - tests/tools/test_file_operations.py + test_file_operations_edge_cases.py + test_file_tools.py + test_file_tools_live.py + test_file_write_safety.py + test_write_deny.py + test_patch_parser.py + test_file_ops_cwd_tracking.py: 228 passed locally. - Live E2E reproduction of the tips.py corruption incident: broken content written; lint field surfaces 'SyntaxError: invalid syntax. Perhaps you forgot a comma? (line 6, column 5)' — the exact error that would have self-corrected the bug on the next turn. |
