What is cached where
~/.frisk/cache/ (set FRISK_CACHE_DIR to move it) holds:
labels/<session-id>.<hash>.json: one label per session.groups/<hash>.json: the intent grouping.skills/<hash>.json: skill drafts.pii-ner/<hash>.json: with--pii-model, the masked entities found in each chunk of text (type, masked value, fingerprint).
Each entry is keyed by a hash of exactly what was sent, plus the analyzer, model and prompt version. A re-run therefore only labels new or changed sessions. The cache holds model outputs only, never transcript text and never a raw sensitive value.
To delete it:
friskme cache clear # or: rm -rf ~/.frisk
friskme models remove # the PII model, if you downloaded it
