### Tools

- `lookup` - Everyday query. q= a borrower, ticker, CIK, or phrase. Short card plus next. full=true is the deep card. Prefer this for a name.
- `get_coverage` - This compile's universe. funds = AG filers (BDCs + interval) plus CLO CEF tape. bdcs / interval / clo split. credits = peeled issuer_id count. total_fv_bn is $ billions; line fv_m is $ millions. meta.compile_id is the snapshot to cite. dictionary[] defines each field.
- `get_issuer` - issuer_id (or q= with one hit, or an exact name) opens the credit card: same-loan marks, family, history. q= matches whole tokens, not substrings. Many hits: thin list. No q: most-held names (thin). preset=disagreement = widest same-loan screen. Do not merge family ids. Do not crawl every issuer_id.
- `get_filer` - Exact ticker or cik= opens the fund card. q= with many hits is a thin list. sort=fv limit=4 is the Allocator starter. get_sector q=software view=funds ranks software books. Chips: BCRED, OCIC, HLEND, ADS, ASIF.
- `get_positions` - Line lookup on one fund SOI. Pass cik from get_filer and q= a borrower. No q: 15 sample lines (limit honors 1-15). Max 100 with q. n is the full tape. Do not sum fv_m.
- `get_disagreement` - The disagreement screen: widest same-loan issuer spreads on the latest common period (4+ holders, 15pt+, vintage hidden). n is issuers, not facilities. Stale interval marks do not rank. Pass issuer_id to get_issuer for the card. cursor pages.
- `get_non_accrual` - Lines the funds footnoted as non-accrual. Optional cik or q=credit name. Default 50. cursor pages.
- `get_sector` - Sectors page. No q: universe mix with denominator_fv_m. q=software|healthcare|industrials. view=credits|funds. Software fund ranking uses membership software_pct. Other sectors use printed mix. sort=fv|pct. cursor pages. cik= one fund's mix.
- `get_software` - Same as get_sector for software. Default q=software. view=funds ranks by membership software_pct.
- `get_clo_tranche` - CLO note holder graph. q= or tranche_key= opens one deal|class (holders, marks, vehicles). No q: cross-vehicle connections (BDC / interval / loan_cef sleeves that share a CEF tranche). view=books is per-CEF field fill vs the canonical standard. Off Find Credit. Not collateral, WAS, or OC/IC.

```
