The Stock Screener. Checks a list of companies against the user's own rules (revenue growth, margins, EPS, P/E, earnings yield, sector, anything in the metrics file), says exactly which rule each company passes or fails and by how much, and ranks the ones that pass into a shortlist. Reads the metrics /trader-analyst writes from SEC filings, or any CSV. Use when the user says "screen for stocks", "find me companies that", "filter my watchlist", "which of these pass my rules…
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
# trader-screener
A screen turns "I want profitable companies that are still growing and not
too expensive" into rules a computer can check, and shows its work: every
pass and every fail comes with the number and the threshold.
Tool in this folder (standard library Python, no network):
```bash
python3 "${CLAUDE_SKILL_DIR}/screen.py" --help
```
## What it reads and writes
- Metrics: `trader/metrics.json` from `/trader-analyst` (`facts.py --metrics`),
or any JSON list or CSV with a `ticker` column. CSV numbers may carry `$`,
`%` and commas.
- Prices (optional): `trader/prices.json` (`{"prices": {"AAPL": 341.27}}`,
any source; `/trader-alerts` writes it). With prices it adds `price`, `pe`
(price / trailing EPS, only when EPS is positive) and `earnings_yield`.
- Rules: a JSON file, `rules.example.json` in this folder to start from.
- Writes `trader/shortlist.json` with `--out`: who passed, their score and
why, who failed and why.
## The rules file
```json
{"name": "Growing, profitable, not priced for perfection",
"rules": [{"metric": "revenue_growth_yoy", "op": ">=", "value": 10},
{"metric": "operating_margin", "op": ">=", "value": 25},

How to install
mdr add jakeschincariol/trader-skill/trader-screener@sha256:058e1167d494bc19The line at the top of this page pins the label git:20261014.5189e79, 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.
