Lightweight read-only view over ~/.opensquilla/logs/decisions-*.jsonl. Aggregates DecisionEntry.skills_invoked (SCHEMA_VERSION 10) into co-occurrence frequencies, joins with SkillLoader.list_meta_specs() for meta-skill usage stats, and surfaces the tests/test_skills/router_fixtures/ corpus.
Usage
uv run python {baseDir}/scripts/explore.py \
--log-dir ~/.opensquilla/logs \
--query "Co-occurring chains for PDF workflows" \
--window-days 30 \
--include co_occurrences,meta_usage,router_fixtures \
--top-k 10
Output
JSON to stdout with keys co_occurrences, meta_usage, router_fixtures, and a placeholder string when the log is empty.
Fallback
If no decision-log exists, return an empty result with a placeholder string explaining "no history; downstream should rely on user intent only".
