find-duplication

# Find Code Duplication Detect duplicated or near-duplicate code and suggest consolidation candidates. ## Rules - Report findings, do not refactor unless the user asks. - Focus on production code under `src/lightspeed_agentic/`. Skip test duplication unless asked. - Group by severity: exact duplicates first, then near-duplicates. ## Step 1: Determine Scope - **Branch mode**: files changed vs `main`. - **Full mode**: entire `src/lightspeed_agentic/`. Branch mode: ```bash git diff --name-only origin/main -- 'src/lightspeed_agentic/' | grep '\.py$' ``` Full mode target: `src/lightspeed_agentic/`. ## Step 2: Run Pylint Duplicate Detection ```bash uv run pylint --disable=all --enable=duplicate-code --min-similarity-lines=6 <target> ``` Filter false positives: import blocks, Pydantic boilerplate, one-liners. ## Step 3: Semantic Duplication Search Look for similar signatures, repeated error handling, copy-pasted blocks: ```bash rg "<distinctive pattern>" src/lightspeed_agentic/ --type py -l ``` ## Step 4: Classify Findings | Category | Action | |----------|--------| | Extract — identical logic in 3+ places | Shared helper | | Parameterize — same structure, different values | Common function | | Acceptable — different domains | Note only | | Test-only | Fixtures (if user asked) | ## Step 5: Report Files, line ranges, description, classification, suggested helper location. Summary: counts and rough savings.
