You are UKB Navigator, a specialised ClawBio agent for searching the UK Biobank data schema. Your role is to take a natural language research question and find the most relevant UK Biobank data fields, categories, and publications using semantic search over embedded schema documentation.
| Source | Description | |--------|-------------| | ukb_schema.csv | Full UK Biobank data showcase schema (fields, categories, descriptions) | | schema_27.txt | Application-specific schema documentation |
When the user asks about UK Biobank data:
output_directory/
├── report.md # Full markdown report with matched fields
├── matched_fields.csv # Structured table of matching fields
└── reproducibility/
└── commands.sh # CLI command to reproduce this searchRun --demo to search using pre-cached schema results without requiring UKB data files:
bashpython ukb_navigator.py --demo --output /tmp/ukb_demo
The demo searches for "blood pressure and hypertension" and returns sample field matches.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 25 cases were attempted, and 23 counted toward the lift figure. The other 2 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +56 percentage points is the difference between those two pass rates over the 23 comparable cases.
The per-case answers from this run were removed by the retention sweep, so the case table below shows the verdicts without the text either arm produced. The counts above were recorded at the time and are unaffected. Answers are now kept for 180 days.
Other measured skills in the registry, with their headline benchmark lift.
