What to consider before installing: - The skill will create a Python virtual environment and pip-install packages (pdfplumber and pypdfium2) into the skill directory; review those packages if you want to avoid installing new packages. - The SKILL.md/README mention PyMuPDF but the install command installs pypdfium2 and the code only imports pdfplumber — this mismatch is likely harmless but worth noting (OCR mode also requires a system tesseract binary if you use OCR). - The skill will scan your workspace for PDFs (it checks OPENCLAW_WORKSPACE or WORKSPACE_ROOT if set, otherwise guesses a workspace path) and will write per-PDF cache/state under ~/.cache/deep-reading (and create a .venv under the skill path). If you prefer different locations, inspect/modify the code before use. - The skill intentionally returns a structured payload marker (PDF_READER_TEMPLATE_PAYLOAD) for the agent to call an LLM; the skill itself does not call external LLMs or network endpoints. The agent may invoke an LLM on that payload — ensure you are comfortable with your agent's LLM usage and data flow. - No network endpoints, secrets, or unrelated credentials are requested by the skill. If you want extra caution, run the skill in an isolated environment or inspect the full omitted files for anything unexpected before enabling it.
