> Configuration: Read the internal documentation path from `.prflow/config.json` using: `"${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../scripts/config-get.sh .docs.internal docs/internal/`. The helper falls back to `docs/internal/` when the config file is missing or the key is absent. Use the result as `[[INTERNAL_DOC_LOCATION]]` throughout this skill. **Portable helper anchor (single-statement).** The bundled-helper commands in this skill resolve the skill directory inline at each call site via `${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}`. When `$CLAUDE_SKILL_DIR` is set and non-empty (Claude Code), run each command exactly as written. Otherwise locate the directory yourself — this text lives in a file inside it, whose sibling `../../scripts/` directory exists — by replacing the placeholder with the skill base directory the runner reports in context (e.g. a `Base directory for this skill:` line) and accepting a candidate only once `ls <candidate>/../../scripts/` succeeds in the same shell the helper commands run in. If a path form is rejected, use the form that shell reports (`pwd` shows it); a Windows-form base directory (`C:\...`) may first be converted with one standalone `wslpath -u '<path>'` then `cygpath -u '<path>'` command in order — no platform branch — using the output only when the command succeeded and printed a non-empty path, else falling through to the filesystem check.
