Optional optimizations run: - - incremental filtering, - - parallel file processing, - - AST cache usage, - - metrics and memory profiling hooks -5. For each file, `_analyze_file()`: - - reads source, - - computes base metrics (LOC/comments/blanks), - - runs each enabled analyzer, - - aggregates `CodeIssue` entries -6. Results aggregate into `AnalysisResult` -7. CLI prints summary, optionally detailed issues, and exits non-zero if critical issues exist - -Default analyzers enabled: - -- complexity -- code_smells -- security -- dependency -- dead_code -- type_hints -- performance - -## 4.2 Report Generation Flow - -Command path: - -1. User runs `refactron report --format <...> -o ` -2. CLI runs the same analysis engine (`Refactron.analyze()`) -3. CLI calls `AnalysisResult.report(detailed=True)` and writes content to output path - -Current behavior note: - -- `--format` is accepted by CLI and set in config, but `AnalysisResult.report()` currently generates text output only. -- So JSON/HTML report formats are not yet implemented in the core report renderer. - -## 4.3 Refactor Flow - -Command path: - -1. User runs `refactron refactor --preview` or `--apply` -2. CLI optionally creates a backup session before apply mode (`BackupRollbackSystem`) -3. `Refactron.refactor()` runs enabled refactorers on each file and returns `RefactorResult` -4.

Orchestrator builds prompt (issue + code + retrieved context) -5. LLM returns a structured response -6. `SafetyGate` validates response and assigns safety score/status -7.

Install editable package and verify CLI. -2. Run `refactron init` in your project. -3. Run `refactron analyze . --detailed`. -4. Run `refactron refactor . --preview` and inspect suggestions. -5. Apply on a small subset first: `refactron refactor --apply`. -6. Use backups/rollback for safety validation. -7. If using AI: - - run `refactron rag index` in connected workspace, - - run `refactron suggest --line `, - - apply only after tests pass. - ---- - -## 9) Suggested Engineering KPIs for Stabilization - -- CLI command success rate (by command and platform) -- report generation correctness (format validation pass rate) -- refactor apply success rate (no manual repair needed) -- rollback success rate -- AI suggestion acceptance rate and safety reject rate -- median analyze runtime per KLOC -- backend dependency failure rate (auth + llm endpoints) - ---- - -## 10) Immediate Action Plan for Your Team (Next 7 Days) - -1. Implement JSON/HTML report renderers and tests. -2. Add integration tests for login and API key verification path. -3. Add refactor apply conflict detection tests. -4. Update docs to match credential storage and current feature reality. -5. Create a single "developer onboarding script" for Windows and Linux/macOS. -6. Run a real repo pilot (at least 10k LOC) and log all failures in a stabilization board. - -If you want, the next step can be a follow-up implementation pass where we directly build: - -- JSON/HTML report generation, -- a safer refactor apply engine, -- and a "production readiness checklist" command in CLI.
