For URL templates, parsing expectations, and examples, read references/endpoints.md.

Workflow

Fetch manager index from home.php via defuddle.
Resolve the requested manager and extract the m= code from the holdings link.
Fetch holdings for that manager.
Fetch activity with typ=a, and optionally typ=b or typ=s if user asks specifically.
Return a concise markdown report prioritizing holdings quality and recent moves.

Output Contract

Use this structure by default:

Manager Snapshot
- Manager name
- Period
- Portfolio date
- Number of stocks
- Portfolio value
Top Holdings
- 8-15 rows prioritized by % of Portfolio
- Columns: Ticker | Company | % Portfolio | Recent Activity | Shares | Reported Price | Value
Recent Movements
- Group notable rows by Add, Reduce, Buy, Sell
- Include share change and % change to portfolio when available
Quick Take
- 2-5 bullets with actionable interpretation (concentration, largest adds/reduces, unusual moves)
Sources
- Include DataRoma original URLs and the defuddle URL used

Data Quality and Fallback Rules

If manager name is ambiguous or not found, offer 3-5 close candidates from the index and ask user to choose.
If activity markdown is noisy or incomplete, prioritize holdings and state the limitation explicitly.
Preserve original DataRoma links for traceability.
Treat this as informational market data; avoid financial advice language.
If a field is missing, show N/A instead of inferring values.
