financial-data-collector

An agent skill by daymade, from daymade/claude-code-skills. Tags: analytics, api, data, finance, sql.

What it does

Collect real financial data for any US publicly traded company from free public sources (yfinance). Output structured JSON consumable by downstream financial skills (DCF modeling, comps analysis, earnings review). Handles market data (price, shares, beta), historical financials (income statement, cash flow, balance sheet), WACC inputs, and analyst estimates. Use when users request collect data for ticker, get financials for company, pull market data, gather DCF inputs, or any task requiring structured financial data before analysis. Also triggers on financial data, company data, stock data.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add daymade/claude-code-skills --skill financial-data-collector

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/daymade/claude-code-skills
cp -r claude-code-skills/daymade-financial/financial-data-collector ~/.claude/skills/financial-data-collector

Safety box score

Grade B, low risk: 14 of 100 risk points, rated 2026-10-20. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This skill collects live US equity data from yfinance and the 10Y Treasury proxy, then writes one JSON file for downstream financial analysis. The main risks are outbound network access to third-party financial APIs and a writable output path; it does not touch secrets, privileges, or hidden/opaque components.

Category levels, from 0 (none) to 3 (high)
Category	Level	Why
Code & shell execution	1 (low)	It runs local Python scripts (`python scripts/collect_data.py ...` and `python scripts/validate_data.py ...`) with third-party dependencies declared in the script header, but there is no eval, shell pipeline, or downloaded code execution.
Network access	2 (moderate)	It makes live outbound requests to yfinance for market/financial data and to `^TNX` for the risk-free rate (`ticker_obj.info`, `ticker_obj.financials`, `tnx.history(period="5d")`).
Filesystem reach	1 (low)	It writes a JSON file to the chosen path via `Path(output_path).write_text(...)`; the write is limited to a single output file and the skill says not to create auxiliary files.
Secrets & credentials	0 (none)	There is no code or instruction to read, request, or transmit tokens, passwords, `.env` files, keychains, or browser sessions.
Privilege & persistence	0 (none)	Nothing requires sudo, global installs, services, scheduled tasks, or shell/OS configuration changes.
Instruction hijack surface	0 (none)	The files do not instruct the agent to ignore safeguards, hide actions, or follow remote instructions; they only describe data-collection behavior and validation rules.
Irreversible actions	0 (none)	The skill does not publish, send, deploy, book, pay, or delete anything; its only side effect is producing the JSON output file.
Transparency	0 (none)	All shipped files are readable text (`SKILL.md`, markdown references, and Python scripts); there are no binaries, base64 blobs, or unpinned remote installers.

Before installing

Review `scripts/collect_data.py` and confirm you are okay with live outbound requests to yfinance and `^TNX`.
Run it in a scratch environment or account if you do not want financial data collection to use your normal network/session context.
Choose an explicit `--output` path so you do not overwrite an existing file by accident.
