programs.codex.skills

Custom skills for Codex.

This option can be either:

An attribute set defining skills
A path to a directory containing skill folders

If an attribute set is used, the attribute name becomes the skill directory name, and the value is either:

Inline content as a string (creates a generated skill directory at <skills-dir>/<name>/)
A path to a file (creates a generated skill directory at <skills-dir>/<name>/)
A path to a directory (symlinks <skills-dir>/<name>/ to that directory)

If a path is used, it is expected to contain one folder per skill name, each containing a SKILL.md. Each top-level skill entry is symlinked into <skills-dir>/, leaving <skills-dir>/ itself as a normal directory so unmanaged skills can coexist.

Home Manager manages skills under CODEX_HOME/skills (typically ~/.codex/skills, or ~/.config/codex/skills when home.preferXdgDirectories is enabled).

    with pdfplumber.open("document.pdf") as pdf:
        text = pdf.pages[0].extract_text()
    ```
