8## Prerequisites
9 
101.  **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
11    `uv` is installed and on PATH.
122.  **User Notification**: If .licenses/literature_search_europepmc_LICENSE.txt
13    does not already exist in the workspace root directory then (1) prominently
14    notify the user to check the terms at https://europepmc.org/ and to always
15    check the license of the papers retrieved by the skill for any restrictions,
16    then (2) create the file recording the notification text and timestamp.

18## Core Rules
19 
20-   **Open Access Only**: This skill exclusively searches open-access content.
21    The script automatically appends `OPEN_ACCESS:y` to every search query. Do
22    NOT remove or override this filter.
23-   **NEVER run python3 or python3 -c directly**: the system Python does not
24    necessarily have all key dependencies. Do not attempt to pip install or
25    create new venvs.
26-   **Use the Wrapper**: ALWAYS use the provided script rather than calling the
27    API directly. The script handles rate limiting (1 req/s) and errors.
28-   **Output Files**: All subcommands require `--output` to write results to a
29    file. Read the output file separately to avoid context overflow.
