similar-code

使用向量搜索（armyknife searchx）在代码库中查找语义相似的代码。在寻找相似实现、重复代码或现有模式时使用。需要symbols.db。

Always use actual code as query input, not natural language descriptions
Prerequisite: symbols.db must exist at project root (built via armyknife searchx index)

Workflow

User provides code as argument (e.g., /similar-code <pasted code>)
Run the search command:

armyknife searchx query '<code>' --limit 10 --database symbols.db

Present results as a table (symbol, kind, file, line, similarity)
Read top matches to show code context

Interpreting Results

| Similarity | Meaning | |------------|---------| | 0.8+ | Very similar (likely same pattern or implementation) | | 0.6-0.8 | Related (similar structure or purpose) | | <0.6 | Weak match |

Limitations

| Input Type | Result Quality | |------------|----------------| | Actual code | Good (designed for code-to-code similarity) | | Natural language | Poor (embedding model is code-focused) |

Code is embedded using embeddinggemma:300m (768-dim) via Ollama.
