sec-13f-analysis SKILL.md skillA
sec-13f-analysis from cxcscmu/skilllearnbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cxcscmu/skilllearnbench/sec-13f-analysis@git:20260424.d50cf5aPins git:20260424.d50cf5a in mdr.lock. Pin the fingerprint instead.

Parse and analyze SEC 13-F filing TSV datasets to extract AUM, holdings count, and fund details by accession number.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SEC 13-F Analysis Skill
## Overview
SEC Form 13-F datasets consist of TSV files downloaded from EDGAR. Each quarter has the same file structure.
## Key Files
| File | Purpose |
|------|---------|
| `COVERPAGE.tsv` | Fund identity: `FILINGMANAGER_NAME`, `ACCESSION_NUMBER`, `REPORTCALENDARORQUARTER` |
| `SUMMARYPAGE.tsv` | Aggregated stats: `TABLEVALUETOTAL` (AUM in thousands), `TABLEENTRYTOTAL` (number of holdings) |
| `INFOTABLE.tsv` | Individual holdings: `CUSIP`, `NAMEOFISSUER`, `VALUE` (thousands), `SSHPRNAMT` (shares) |
| `SUBMISSION.tsv` | Filer metadata |
## Common Tasks
### Load data with pandas
```python
import pandas as pd
q3_dir = "/root/2025-q3"
coverpage = pd.read_csv(f"{q3_dir}/COVERPAGE.tsv", sep="\t", dtype=str)
summarypage = pd.read_csv(f"{q3_dir}/SUMMARYPAGE.tsv", sep="\t", dtype=str)
infotable = pd.read_csv(f"{q3_dir}/INFOTABLE.tsv", sep="\t", dtype=str)
```
### Get AUM for a fund (by accession_number)
```python
row = summarypage[summarypage["ACCESSION_NUMBER"] == accession_number]
aum_thousands = int(row["TABLEVALUETOTAL"].iloc[0])
aum_dollars = aum_thousands * 1000
```
### Get holdings count
```python
…Read the whole file at its exact version.
How to install
mdr add cxcscmu/skilllearnbench/sec-13f-analysis@sha256:7ad06635e1d810feThe line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
