Skill

What to consider before installing: - Functionality: The code and instructions match the advertised M&A/valuation purpose (fetch EDINET filings, parse PDFs, calculate metrics, export Excel). - EDINET API key: If you want the skill to auto-download filings, you must provide an EDINET_API_KEY in your environment. The skill metadata did not declare this requirement — expect the fetch script to fail if the key is missing. Only provide that key if you trust the skill and run it in a controlled environment. - Packages/install: The skill installs standard Python libraries (httpx, pdfplumber, openpyxl). The installer uses 'uv' by default but pip3 is an alternative; if you prefer, install dependencies yourself with pip3 in a virtualenv. - Data handling & network: The scripts will access the network (EDINET API and download URLs) and will read any PDFs you supply. Do not upload sensitive non-public documents you don't want processed or stored. The code prints downloaded file paths and writes files to the specified output directory. - Safety steps: Inspect the three Python scripts yourself (they are short and readable). Run them in an isolated environment (Python venv or container) and avoid giving unrelated credentials. If you need automatic EDINET fetches, consider creating a restricted API key and monitor network activity. - If unsure: If you want to avoid any external network calls, use Option A/B (paste data or upload PDFs) rather than enabling the EDINET auto-fetch path. Overall: the skill appears coherent for its purpose but has a notable metadata/instruction mismatch (undeclared EDINET_API_KEY) and uses an uncommon installer wrapper; verify these items and run in a sandbox if you have security concerns.
