name	review-duplicates
description	Duplicate code detection using similarity-rs. Identifies refactoring candidates based on semantic similarity.
user-invocable	true
context	fork
agent	code-refactor-agent

When subagents are enabled in Codex, prefer delegating this workflow to the code-refactor-agent custom agent.

Detect duplicate code in the ccswarm codebase using similarity-rs.

similarity-rs crates/ --threshold 0.80

For Rust code, also consult cargo coupling so duplicate cleanup is prioritized by architectural impact, not only by textual similarity.

cargo coupling . --summary --exclude-tests
cargo coupling . --hotspots=12 --exclude-tests

If a duplicate cluster is located in a coupling hotspot, high-risk boundary, or cycle-related module, raise its refactoring priority accordingly.

Classify results by priority:

Priority	Condition	Action
High	95%+ similarity, 10+ lines	Extract to common function
Medium	90-95% similarity, 5+ lines	Consider trait or macro
Low	85-90% similarity	Evaluate structural similarity
Skip	Test code, config structs	Allow intentional duplication

Output a JSON report with high_priority, medium_priority, low_priority, and ignored sections.
