Incremental Analysis

Algorilla caches analysis results per file using content hashing. On subsequent runs, only files whose content has changed are re-analyzed.

How It Works

1. First run: all files are parsed and analyzed. Results are cached to .algorilla/analysis-cache.json
2. Subsequent runs: file content hashes are compared. Only changed files are re-parsed
3. Cached findings from unchanged files are included in the output without re-analysis

Cache Location

The cache is stored at .algorilla/analysis-cache.json relative to the scan root directory.

Disabling the Cache

algorilla --no-cache .

Performance Impact

Typical improvement on a ~1500-file codebase:

Run	Time
First (no cache)	~1.4s
Second (cached)	~0.1s

Cache Invalidation

The cache is automatically invalidated when:

• A file's content changes (SHA-256 hash mismatch)
• The cache file is corrupted or from an incompatible version
• --no-cache is specified

To manually clear the cache, delete the .algorilla/ directory.
